1, high efficiency and energy saving water curtain cooling system is the use of the combination of fan and water curtain to reproduce the natural water evaporation cooling in the physical process, the power consumption is only 1/10 of the traditional air conditioning.
2, ventilation and ventilation in the whole system in combination with the ventilation fan quickly exhausts indoor personnel, the heat produced by the machine, exhaust gas, odor to avoid the exhaust and odor to the human body. The whole indoor air can be updated at the fastest speed in one minute. This is the effect that ordinary air conditioning can not achieve.
3, improve work efficiency to solve the problem of attentional decline due to stuffiness and lack of oxygen. The use of water curtain can not only solve the problem of plant muggy, but also produce the negative ion oxygen to increase the oxygen content in the air and reduce the fatigue to improve the working efficiency.
4. The health and environmental protection system uses water as a refrigerant. In the process of manufacture and use, there is no pollution to the environment. In addition to reducing air humidity, the water curtain can also purify the dust and particles carried by foreign air. Efficient recycling of fresh air can effectively prevent occupational diseases and spread of infectious diseases.
5, applicable strong water curtain factory air conditioning system applicable to a wide variety of crowd intensive heat source, or easy to produce pollution, ventilated places can play a significant effect. Such as textile workshop, clothing workshop, injection workshop, hardware factory, shoe factory, electronic factory, etc., the corresponding water curtain cooling system can be designed according to its different environment and the wind speed and air volume are very flexible with the specific conditions of the room. 05
Advantages of cooling water curtain
Secret of e-commerce details page
For the baby master map, the Title Optimization, the selling point expression, the details of the introduction, I believe that these are not strange to us, because they really affect the transformation of our shops. Today, Xiaobian wants to discuss with you the optimization of shop details page.
There is no doubt that the details page is the most important page in a shop, because every detail page is the landing page of the flow entrance. It is not only responsible for answering questions and puzzles, but also changing the list, and also playing the role of deep browsing. The details page consists of three parts, namely, visual, copywriting and layout, and the three are indivisible.
One: Everything starts from the vision
The importance of vision is self-evident. On the one hand, the appearance of the products and brands can not be separated from the vision. On the one hand, the electric business can not see the object, and all depends on the vision. So the vision is almost the most important part of the e-commerce marketing means. It is often said that the biggest disadvantage of online versus offline is the inability to perceive products. This is not false, but in the visual presentation, the line has a bigger advantage than the line. Using the flat design of the sky and the sky, and the model with beautiful personality, the visual sense of the line can show the beauty of the product, and it can attract the eyeballs of the consumers. Therefore, we must grasp this advantage and create a completely different feeling and effect through visual design, style presentation or value creation.
For visual design, all efforts are for the purpose of “conveying” two words. Vision is not equal to vision itself. The task of vision is to convey things to users: why should we choose this product? What are the benefits of the product? How to make users feel intuitively? How do you affect the user’s decision? No matter what visual plan we want to build, we must grasp the core of “communication” so that we will not deviate from the direction.
The elements of vision to be conveyed:
1, aesthetic feeling: man is a visual animal, and vision is related to aesthetics. And the aesthetic is top-down, even if the pursuit of cheap low price customers, do not mind the brand shop page to create a more beautiful point. People’s eyeballs are always attracted by the “beautiful” vision first. Although everyone’s aesthetic is subjective, the aesthetic of the masses has a unified standard, for example, the arrangement of words, alignment, gathering, white, noise reduction, contrast and other arrangement principles, if not to follow, will destroy the overall aesthetic.
2, brand temperament: brand in the visual creation, in addition to the aesthetic, but also the image of the brand positioning, such as brand VI, positioning perception, and so on, the basic elements of these brands, through fine planning and design, and adhere to a long and consistent delivery, so that more users can get the cognition, the second is deepened Brand influence gives consumers a brand image.
Two: the plan of copywriting
Because the mobile phone screen is small, if we use a screen to display the information content of a PC page through the mobile end, the information will be crowded and the text will become less clear. That is, the mobile terminal directly copies the PC picture vision, the biggest problem – the copywriting is invalid. To solve this problem, we need to make different designs for mobile visual copy. In particular, the following principles should be followed:
1, enlarge the title, enlarge the title text on the picture, play a clear role, and summarize the total information with fewer words. This can increase the attractiveness of users, even if users glance at it hastily, and know what you want to express.
2, reduce the content of the copywriting, the copywriting is not much in essence, the copywriting of the mobile end is especially so, the text is too many, in a small screen, either it appears too small, not easy to read, or too many words, affecting the display of the picture.
3, the text is clearly displayed, writing is an important part of the vision. It is both an explanation and a supplement. It is also very important to make a clear display of the copywriting. First, the picture background, the background of the text must be simple and clean, and the presentation of the text. Secondly, when long text descriptions are required, row spacing should be arranged as much as possible to increase the row spacing, so as to facilitate the clear display of the text.
In fact, no matter how we present the product at the mobile end, the details that we see through the product are not compared to the PC end, so the details of the product and the detail close-up can make up for this shortcoming. Of course, we must follow the principle of vertical screen when designing.
Three: detail page arrangement
The details page is an important place to convey information, so understand the core issue of the details page:
1, who you are: let the customer know what you sell and convey the location of the store.
2, what is the use of your product to users? That is, knowing the pain points of customers, and highlighting product selling points accordingly. But no matter what any product can bring to the user, that is, the selling point is impossible only one, if there are many selling points, we should understand the choice and focus, because “too many selling points, equal to no selling point”.
3, why choose you: when you encounter homogeneity or similar style, users will always be faced with the problem of choice, that is, why do users choose you? In addition to shaping the excellent sense of the product itself, it can also be analyzed from the perspective of “competing products contrast”, to foster strengths and circumvent weaknesses, and to highlight itself.
Cause and solution of abnormal pressure difference of bag filter equipment
The cause of abnormal pressure difference of bag filter and its solution. The dust cleaning system of the bag dust collector has 3 kinds of cleaning methods: timing, constant pressure and manual cleaning. The basic purpose of dust removing bag cleaning is to control and stabilize the pressure difference. How to find out the reasons and solutions if the pressure difference is abnormal in the bag filter equipment? .
The reason for the control of pressure difference by the equipment of the bag dust collector:
First, timing control differential pressure is simple, but not the most economical way.
Two, artificial timing does not ensure that every time the filter bag needs cleaning, it will be cleaned.
Three, usually, the pressure difference of the bag filter can be controlled, how much is it good, how much is it more scientific? The working experience of the company’s factory for many years, the running resistance of the common bag dust collector will be adjusted and controlled above 1000Pa, and the high is only 2500~3000Pa, if it is as high as 6000Pa, It is not normal, at this time we can judge that it is the problem that the dust bag or the dust collector equipment has a high resistance, or the problem of the burning of the cloth bag.
Four. When the boiler coal industry used the bag filter in our country, the running resistance is also under 1000Pa, which can reduce the energy consumption of the dust collector, but this control reduces the efficiency of the dust removal, shortens the life of the filter bag, and the economic burden is also aggravated.
Biomass boiler dust collector (2)
Bag filter
A solution to the abnormal pressure difference of the bag dust collector
Reason check: (1) the dust of the dust bag is too much, it can be more troublesome through multiple vibration cleaning, cloth bag blockage (the import humidity is too large or the ignition oil does not burn out the adhesive bag), it may reduce the load operation or lead to the stop of the furnace according to the load of the fan.
Treatment measures: temporarily remove a filter chamber and then speed up ash transportation, and use the ash conveying power to carry out the reverse blow filter chamber.
(2) the dust removal device of bag filter has lost its proper function, making the dust layer adhered to the surface of cloth bag thicker and thicker resulting in sudden increase of pressure difference.
The cause of abnormal pressure difference of bag filter and its solution. More about the product knowledge of bag filter can contact us.

Advantages and disadvantages of hydraulic press sensors
Advantages and disadvantages of hydraulic press sensors
As we all know, there are sensors on the hydraulic press, but most people do not know how many kinds of sensors exist in the hydraulic press. What are their advantages and disadvantages? The following is a brief introduction to you.
Semiconductor gas sensor: semiconductor gas sensor has become the most common and practical gas sensor. He has the advantages of low cost, simple manufacturing, high sensitivity, fast response, long life, low humidity sensitivity and simple circuit. The disadvantage is that it must work at high temperature, poor selectivity to gas or odor, dispersed component parameters, unstable stability and high power.
Electrochemical gas sensor: the electrochemical gas sensor detects the concentration of the gas by detecting the current, and divides it into a primary battery without power supply and a controlled potential electrolysis that needs power supply. At present, many toxic gases and oxygen can be detected, and the latter can also detect the oxygen concentration in the blood. The main advantages of electrochemical sensors are high sensitivity and good selectivity of gas, and short life.
Solid electrolyte gas sensor: solid electrolyte, which is a chemical cell with solid ion conduction as electrolyte. It is between semiconductors and electrochemistry. Selectivity, sensitivity is higher than semiconductor and life is longer than electrochemistry, so there are many applications. The drawback is that the response time is too long.
Contact combustion gas sensor: contact combustion gas sensor can only measure combustible gas. It is also divided into direct contact combustion and catalytic contact combustion. The principle is that the gas sensitive material is burned on the surface or under the action of catalyst under the state of electricity. Because the temperature of the gas sensitive material increases, the resistance of the gas sensitive material is changed. The latter is widely applied because of its broad spectrum relationship.
The above mentioned sensors on the hydraulic press have their own advantages and disadvantages. I hope you will have a good understanding of them.
6 tips on the success of the 3 months
An industry has been doing it for several years, and suddenly it is very difficult to change it. Many people tell me that freelancers are so cool. I also want to be. Can you tell me how to succeed in transition?
For transformation, the biggest difficulty is that it is economically difficult and risky.
But it’s not all the same. Chris once said, “natural talent will help you move forward, but it can’t protect you forever. You need entrepreneurship, but at the same time you need experience and patience to get things done. “
The specific recommendations are as follows:
01, upgrading skills
The cost of acquiring skills is now very low. You are sure of your new industry, so go to the class, or you can go to other relevant companies, and if you have an economic basis, go directly to the training class.
02, now start saving some money
Because in the transition period, you have to eat and drink, and you have to spend money on your studies. Now that you still have your salary, you can save a little bit every month. Maybe take money to make money, interest is also OK, the key is not to spend.
03, learn the knowledge of advertising marketing
What’s the usage? It’s very useful. You have to learn to sell yourself. Do you know why there are many talented poor people in the world? Because they don’t know how to sell themselves, they always feel that they are talented. They should be looking for him.
But the smell of wine is really afraid of the alley because the price of storefront is always higher than that of the alley.
So learn a point of marketing positioning knowledge, no matter what you do in the future, or as a freelancer, in the shortest possible time, let the interviewer clear your advantage, let customers find your personality characteristics.
04, reading, writing records
I suggest that you have the lowest cost, but the most effective thing, perhaps you do not love reading, and do not love writing, but for the future, insist on 6 months, enough.
Because after 6 months of persistence, you will find that you have fallen in love with these two things.
05, reduce the cost of life and temporarily reduce the living standard
In a difficult period, a difficult way is to be used. Why do you say you want to be wronged yourself? If you don’t feel wronged, then you can continue to feel wronged and do something you don’t like.
06, learning to change anxiety
There may be a blank period, you will be anxious, do not know if you can persist in this way, can you succeed? What do you do when you are sick and have no money to see a doctor? I’m not self disciplined enough to learn how to do it?
Try to learn to meditate. The first thing that many millionaires get up in the morning is meditation and reading. Now you think you’ve lived a millionaire’s life, and you can turn your anxiety well.
It is true that hard work and diligence are right, but the farther you can go, the spiritual driving force. After all, the body, we are still young now, and can survive.
The number of drawings in the machining of a lathe
1. Under no ready-made processing surface, the plane is divided into four sides, the center is opposite to the original point, the top face zero, and the top face is not normally (copper) to stay 0.1, that is, when the touch number is, the actual pair is 0 (z), and the figure is 0.1 lower.
2, when there is a ready-made processing surface, the ready-made image on the map faces 0 (z), and the plane can be divided into the middle. Otherwise, the actual side touch number (Dan Bian) processing surface should check the actual height, the width, the difference between the length and the drawing, and program according to the actual material. In general, the shape is first processed into the size of the graph and the shape of the graph is reprocessed.
3, when more than one position is needed, the first position (standard position) will be good for the other benchmarks and the gongs are all long and wide. All the next processing benchmarks should be based on the above processed surface.
4. Position the insert: put it in the whole, place the underneath a certain height, and then the drawing will also raise this height. The plane is locked in the whole partition, the height is locked with the silk under the map; the square is straight, the rough one can be divided into the maximum shape; cut a fixture, according to the fixture, the relative of the insert drawing and fixture. Position determination and place the origin of the drawing at the center point of the fixture.
Cutting path selection in CNC processing
1. Surface dredging
The key is the choice and face of the scope.
The area of tool path processing is based on the principle that the selected surface of the selected area is the terminating surface and the highest point to the lowest point where the tool can go down. The best surface is the whole body, and the boundary is only the area to be processed. The distance is less than half the diameter of the knife, because the other side has enough allowance to protect it automatically. It is best to extend the lowest line because there is a R gong at the lowest point.
The choice of knives: if the tool can not be helical or slash feed, or the area where the machining area can not enter the knife area, it will be closed for two times.
Before cutting the knife, it is necessary to open the rough area, especially the small angle, which includes two dimensional angle, three dimensional angle and the sealed area, otherwise the knife will be broken. Small partners who like machinery can focus on intuitive mechanical micro signals. The two time is rough: generally choose the range of 3D trenching, flat bottom knife, and can use planar trenching and shape tool path. In the case of no injury to other surfaces, the tool center to the selected boundary, generally not the boundary of repair, with a fast two-way angle as the situation, the spiral knife, the angle 1.5 degrees, 1, when the groove shape is bar, the spiral knife can not use the oblique line, generally open the filter, especially the surface of the rough surface, the plane can not be lower, the plane is not low, the plane can not be lower, the plane is not rough. In order to avoid the knife, the safety height can not be low.
Draw back: generally do not need to return the knife relatively, use absolute retreat knife, when there is no island, use the relative retracting knife.
2. Plane dredging
Milling a variety of plane, concave groove, when the milling part of the open plane, the need to set the boundary, the principle can be knife (greater than a knife diameter), the opening section is more than half a knife diameter, closed outside.
3. Shape
When the selected plane is suitable for the shape of the shape, the knife (plane shape) is raised with the shape of the shape. When the knife point and the knife point are one point, the knife z plane is not required to lift the knife, and the relative height is not used as much as possible; the correct direction is generally right (CIS).
4, the tool path setting of mechanical correction
The correction number is 21, instead of the computer correction, the feed is vertical feed, and the tool can not go beyond the R.
5, equal high shape
It is suitable for a closed surface. If the open face is four circles, it will seal the surface. If it is within four circles or not four circles, the range and height should be selected. For opening the rough condition, the machining distance in any plane is less than a knife diameter, if the diameter of a knife is larger than a knife, it will use a larger knife or two second high. Shape.
6. Surface streamline
With the best uniformity and dry brittleness, it is suitable for light knife to replace the contour.
7, radial knife Road
It is suitable for a large hole in the middle (Shao Yong). Note: the knife, the knife is not sharp, the knife is too long, the workpiece is too deep to walk around, the workpiece in the corner of the side of the surface should be divided into two knife Road, not the past, the edge of the knife when the best extension (with the arc line knife).
The clear angle of CNC processing
1, the clear angle of the clear angle here is a two-dimensional dead angle, which is not a part of the previous process, such as the light knife need to go to the place to clear the corner and then light knife, too small and big deep corner can be divided a few knives, do not use a knife to clear too many places.
2. Clear 3D corner: open some small troughs, some 3D corners.
3, easy to break the knife, we must consider such as fine knives, too long, too much processing capacity (mainly Z direction, depth direction).
4, knife Road: using two-dimensional shape, only clear the small angle (R0.8) and two-dimensional plane angle; with parallel knife Road, with the contour of the same height; a local knife can not go to the surface and the shape of the dead angle must be sealed first, the final clear corner, the small gap in the large surface generally first sealed up.
CNC processing medium light
1, medium light: steel and fine steel as curved surface.
2, principle: when the knife is thick, there are more layers and layers. It is a process to achieve better results when the light knife is used.
3, features: fast clearance, large knife flying knife can also, large feed, large spacing; no need to avoid the surface quality; the plane of the workpiece must not be light; the high shape of the workpiece does not use light, and when the high shape is open, the two processes can be put together, the surface allowance and the distance between the layer and the layer; need not light, also need not medium light, return One important factor is the working material, the harder the material is, the light is considered; the best processing direction of the medium is better than that of the light knife.
CNC machining light knife
Light knife is to meet the assembly requirements of various products and molds, so it is very prudent to provide different tool path settings and parameter settings according to different requirements.
1. The height of the knife and the final height of the light knife are changed to 0, and the tolerance design is less than 1 silk. There is no need to filter (the smaller the workpiece, the smaller the tolerance, the tolerance will affect the appearance).
2, the front mold and parting surface should achieve the best finish, and the back mold can be repeated.
3. The design of the tool path is determined by the following factors:
The specific shape (such as plane and other surfaces), steep surface and flat surface.
Whether there is a right angle between the two sides (the angle is separated).
Whether the two part requires different (whether to leave allowance, allowance, and the requirement of finish).
The problem of the protection surface in the light knife is a big problem. The error in the processed surface must be protected and protected according to the requirements of the surface. Scope protection, excluding error 0 protection, height range and plane coverage; protection surface protection.
When the knife path is extended, it is better to use arc cutter to process the edge of the blade in the light knife, otherwise the surface will be lengthened in advance.
The problem of cutting the knife in the light knife. Lift a knife to waste time, so try to avoid lifting a knife.
Method 1: set knife gap (small gap)
Method 2: cover, seal the lifting place (small gap).
Method 3: avoid the gap (large gap)
Method 4: extend to the same height when the contour is high
In the light knife, the first feed must be moved from outside the workpiece, avoiding vibration and bruising, and all light knives must be knives.
The problem of tool wear: when the workpiece is large, it needs more than one knife to finish the same workpiece.
