How to solve the noise of hydraulic oil pump?
Once the hydraulic pump fails, it will immediately affect the normal operation of the hydraulic system. Noise is a common failure of hydraulic pumps, but how to detect and eliminate them? With the big LAN hydraulic small editor to see to understand.
There are 10 reasons for the noise and abnormal noise of hydraulic pumps.
(1) the filter or suction pipe part is blocked or through a small area. At this point, what we need to do is to clean the filter element or suction pipe, and replace the appropriate filter or suction pipe.
(2) the gas hole of the tank is blocked. This requires us to clean the air holes.
(3) the oil suction position is too high or the oil level of the tank is too low. At this time, we should reduce the installation height of the hydraulic pump or fuel to the oil level line.
(4) the hydraulic oil pump or suction pipe is not well sealed. At this time, we should check the tightness of the joint and the joint surface and tighten it.
(5) inhalation of bubbles. The oil pump on the new installation is more common. We have to carry out the empty operation and exclude the air; the oil suction pipe is separated from the oil pipe in a certain distance, so that the back of the oil pipe is inserted under the oil surface to a certain depth, and the oil pipe can not be placed above the oil surface.
Undefined
(6) the viscosity of the oil is too high. This requires us to check the oil quality and select the viscosity of the oil according to the requirements.
(7) the suction cavity of the hydraulic oil pump is not smooth. At this time, we have to dismantle the pump and carry out the cleaning and inspection.
(8) the internal parts of the bearing parts of the hydraulic oil pump wear seriously. At this time we have to dismantle the pump and repair or replace it.
(9) the structure design of the hydraulic oil pump is not good, and the oil trapped is serious. This can only improve the design and improve the unloading capacity.
(10) bad installation of hydraulic pump and poor coaxality between pump and motor. This time there will be some abnormal noise. We have to re install the pump to meet the technical requirements.
From the above analysis, we can see that the noise of hydraulic pump is caused by many reasons. The small hydraulic editor of Da LAN reminds us that we need to conduct detailed investigation to identify and determine the real cause.
Structure and design of hydraulic system for mobile crushing station

A few things that a successful businessman must do every day
Products, lack of sales, the Internet has become the only way we start.
If we are not the Internet, we will not be able to get home. We are making products, but for whom? Before the big company work too easy Amateur Open Taobao store, then why do we not also put our products on the network sales, so the cost is greatly reduced, think of the second days I found the network platform to find the same day, Ali registered the good faith, has been on the online transaction so to now all my guests All households are online, and some online customers will bring customers who are not Internet users in their area. But slowly, there are some bottlenecks.
The first thing: close attention to the change of data
The word “big data” is very popular now. In fact, the small data in Ali is also important. The first thing to go to work every day is to go to Ali Wangwang, click on the “daily focus” that pops up automatically, and see the “seller’s growth” plate, which has a “business staff”. I will arrange a day’s work based on the data provided by this plate so that I can get the remedy, because the data is the most true response to your website.
Undefined
From this data perspective, some people may think that such a display is not high, 5A business does not seem to be difficult. Here we need to explain, because our company mainly produces pressure riveting screws, car car charging hardware, plastic screws, machine meter fasteners and other kinds of electronic products. And the customers of search electronic products are very strong in terms of purpose, and the probability of transaction is relatively high. Yesterday, clicking 94 times showed that 94 people visited our shop.
Second things: a new product on a daily basis
Uploading a new product every day will bring a lot of traffic to the store. This is not the secret, the emphasis on insistence, if you and I, insist on adding new products to the shop every day, the flow of shops will gradually increase, insist on continuous optimization and promotion, I believe you will see the return soon. Sometimes, what you lack is the insistence of a new product every day.
The third thing: insist on optimizing the title of the product
In addition to clearly expressing product attributes, I also suggest that you should think more about the key words they may search for when the title is optimized. And some words, such as “good quality” “XX”, “good back” and “good word of mouth”, don’t have much to write, because customers rarely search for them. Too much useless keyword accumulation will only take up space, and the gains will not pay.
At the same time, you can also compare your key words with your peers and combine your own characteristics.
Diamond is the hardest, why can it be processed?
Diamond is the hardest material found so far. If the tool material must be hardened to the machined part, it is a necessary condition for the cutting process, so the diamond can not be machined. But if we expand our minds. Do not use solid cutting tools to process, so the problem of diamond processing may be solved.
In recent years, many special processing methods have been created in the world, such as electric spark, electron beam, ultrasonic wave and laser processing. These machining methods are not processed by solid cutting tools, so the hardness of machined parts is not limited. For example, the principle of laser drilling is to focus the high-energy laser beam on the surface of the component, and this small area produces extremely high temperature. As a result, the surface material is rapidly melted, the well is vaporized rapidly, and holes are formed on the surface of the parts.
Therefore, most materials, including diamond, can be perforated by laser. Therefore, the application of laser drilling is becoming more and more extensive. For example, the spray head used in the chemical fiber industry, the fuel nozzle of the rocket, the cemented carbide or the diamond, and the gemstone bearings in the table all have to be processed with laser to produce small holes on very hard materials.
How the polishing wheel is made by classification of polished materials
hat materials are used for polishing? Polishing wheel, polishing belt, cloth wheel, polishing wax and other materials, polishing is the polishing method of smoothing surface by cutting, plastic deformation of material surface and removing the bump after polishing. Generally, oil stone strip, wool wheel, sand paper, etc. are mainly used by manual operation, special parts such as the surface of rotary body, and auxiliary tools such as turntable can be used. The method of ultra precision polishing can be adopted for high surface quality. A number of polishing wheels are pressed together, and each polishing wheel is coated with a polished oil layer on the outer surface. So in the process of polishing, there is no need to add another oil. And because of its simple structure, it is very popular. So what does Han Tong lapping tell you about the classification and manufacture of the polishing wheel?
Polishing material polishing wheel material and polished wheel is different, it is made of a variety of elastic better cotton, fine felt, silk, wool wheel and other kinds of made. And in order to save cotton wool fabrics commonly used special paper made of cloth replacement is widely used. There are many classifications in the manufacture of polishing wheels. The hardness is determined by the distance between stitches. The smaller the distance, the higher the hardness. Therefore, in order to make the polishing wheel more flexible, we should pay attention to the distance between the stitch and the wheel edge.
The precision grinding should be removed from the coarse sand eye, and the polishing time should be sufficient. When the large workpiece is polished by Shenzhen Han Tong industry, the polishing material is also carried out with a special air cooling device. The polishing wheel can be divided into three ways. The first is a non sutured whole cloth wheel. It is made of fine cotton cloth, suitable for polishing complex workpiece, or for fine polishing of small workpieces. The second is suture. Most of them are made of coarse cloth, non-woven fabric and thin flat cloth. The stitches of them are concentric circular spiral type and direct radiation, which are suitable for polishing various coatings and simple work. Third is an air – cooled cloth wheel. The 45 degree angle line method is adopted, and the circular ruffle is provided with metal discs in the middle, which has the characteristics of ventilation and heat dissipation, and is suitable for polishing large workpieces.
30 year experience expert: process and points for attention in sandblasting process
30 years of experience experts: sand blasting process and the main points of attention; sandblasting Technology: sandblasting and shot blasting which is better? Today, the professional team of Han Tong Industrial Co., Ltd. 30 years professional team research and development experts to say “the key points of sand blasting processing, sand blasting processing and shot processing which is better”, let you have more understanding of the industry in addition to the prior understanding of the shot processing.
The main points of the sand blasting process are that the first sand blasting equipment is as close to the work as possible to reduce the length and pressure loss of the pipeline, avoid excessive pipe wear and facilitate the construction personnel to connect with each other; the sand hose is striving straight to reduce the pressure loss and the concentrated wear of the abrasive to the hose. In order to prevent leakage and air discharge, reduce the number of displacement, increase the use efficiency and efficiency of the abrasive, the spray position should be considered, the injection route is set up, the air pressure, the amount of sand out of the air and the surface pollution of the structure. The moving speed of the nozzle is mastered flexibly.
During the injection process, the metal injection process is adjusted in time according to the air pressure, the diameter of the nozzle, the corrosion state of the structure surface, the quality and efficiency of the treatment. After the surface pretreatment, the dust and debris are cleared with dry and oil free compressed air. The surface of the cleaned surface shall not be touched by hand; before painting, it is found to be found. The surface of the matrix metal is contaminated or rusted, and it must be retreated. After the pretreatment is completed, it needs to be sprayed as soon as possible, and the shorter the time the better. In wet or industrial atmospheric pressure and other environmental conditions, it is necessary to finish the coating in 4h, sandblasting in sunny days or when the temperature is small, and the longest interval of the processing of sand blasting in Han Tong industry is not more than 12h. This is the process of sand blasting process and the main points for attention.
What’s the deburring technology
What does the deburring technology have? A bit, drunk you and me! What’s the technology of burr technology? With the rapid development of engine manufacturing technology, such as -3C, consumer electronics, computer, mobile phone, watch, aviation, aerospace, and automobile, more and more surface deburring, three – and four – way parts are widely used.
In the process of metal surface treatment, we use the technical means to help remove burrs, and plan for the next project. Because people know more and more clearly about the harmfulness of burrs, people have explored various ways and means to eliminate burrs. Many international organizations are now exploring ways to reduce burr formation or burr free measures. It is in the process of product planning and technology planning that we think of possible burrs and minimize burrs. Manual removal of burrs is not required for burr size, burr symmetry and severity in various ways to remove burrs.
When the problem is put forward to the design of a part of the hydraulic system of the roadheader, many deburring technology reports point out the words “remove the burrs at the intersection of each hole”, but some people doubt that the processing cost is more difficult, the processing cost is increased, and the processing cost is increased. Workers often ignore the burr process, and some designers do not pay much attention to it. They often write “deburring” or “edge blunt” on the drawing. In fact, it is a very important process to go to the burr. In the hydraulic system, once the burr on the part falls off, when the component is entered, the slide valve will be stuck, the surface of the part is damaged, the hose is cut or the liquid port is blocked, which affects the performance of the main engine and even stops. If burrs fall on the positioning base surface, the machining accuracy will be affected. Burrs are also easy to scratch workers, affecting assembly quality and parts life.
With the development of science and industry, the technology of deburring technology has attracted more and more attention. In foreign countries, such as the developed industrial countries such as the United States and Japan, there are specialized research institutions, which have done a great deal of research on the mechanism of burr, deburring and testing methods, and the design of special tools. In recent years, China has also carried out practical research work and achieved gratifying achievements.
