Mechanical processing friends to buy precision tube, do not map cheap.

Now the precision tube process is complicated and the precision is higher. Some manufacturers use the two grade tube to pull out to be good, a penny of the goods, and introduce the standard production process of the precision tube to you.

Precision bright seamless steel tube is a kind of high precision steel pipe material after finishing or cold rolling. Because the inner and outer wall of the precision light tube has no oxidation layer, high pressure and no leakage, high precision, high smoothness, cold bending, no deformation, expansion, and flat crushing, all kinds of complex deformation and mechanical processing can be made. Steel tube color: bright white medium with high metallic luster.
The chemical composition of the precision tube is carbon C, silicon Si, manganese Mn, sulfur S, phosphorus P, chromium Cr. Precision light tube process introduction: high quality carbon steel, finishing rolling, non oxidation bright heat treatment (NBK state), nondestructive testing, steel pipe inner wall with special equipment brushing and high pressure washing, rust proof oil on steel pipe as antirust treatment, both ends sealing as dust control.
The main purpose of the precision tube is to produce pneumatic or hydraulic components, such as cylinders or cylinders, which can be seamless and welded. Automobile, machinery fittings and so on have high requirements for the accuracy and smoothness of the steel tube.
Now the precision steel pipe users are not only the users with higher precision and smoothness, because the precision of the precision bright seamless steel pipe is high, the tolerance can be kept in the 2–8 wire, so many machining users are slowly changing the seamless steel pipe or steel steel to the precision seamless steel tube in order to save the loss of work, material and time. .

The big truth of small stories

wo travelling angels lodge at a wealthy family. The family was not friendly to them, and refused to let them spend the night in the comfortable guest bedroom. Instead, they found a corner in the cold basement. When they made the bed, the older angel found a hole in the wall and repaired it by hand. The young angel asked why. The old angel replied, “something is not what it looks like.”
Second nights, two people went to a very poor farm to stay overnight. The host and his wife were very enthusiastic about them, took out the only little food they had, entertained the guests, and then gave up their beds to two angels. Second early in the morning, two angels found that the farmer and his wife were crying. Their only source of life – a cow died. The young angel was very angry, and he asked the old Angel why, the first family had everything, the old Angel helped them mend the wall, and the second families, though so poor, entertained the guests, and the old angels did not stop the cow’s death.
“Some things don’t look like that. The old angel replied, “when we spent the night in the basement, I saw from the wall hole that the walls were full of gold bullion. Because the owner was confused by greed and unwilling to share his wealth, I filled the hole in the wall. Last night, the God of death came to call the farmer’s wife, and I replaced the cow with her. So there’s something that doesn’t look like it looks like.
Small story: sometimes the surface of things is not what they really should be. If you have faith, you only need to believe that giving is always rewarded. You may not find it until later…

How much do you do about old customer marketing

On the topic of old customers, it makes many shopkeeper and operators worried. Why, because they all know that old customers are important, but they can not start. Some stores, drilling in the short message group, how to sell SMS how to chase the tide, how to improve the ROI SMS, and even the software of a group of SMS is an old customer marketing solution, also drunk. Regarding the misunderstanding of old passenger marketing, I sum up three crimes:
1, bought is the old customer?
Be sober. Those who have disappeared before buying are flying geese flying across the sky. To put it plainly, those who buy less than 3 times are not old customers, and the number of purchases is about 5 times. Regular consumption is the real old customers.
2, group information to maintain old customers?
In recent years, advertising messages instead of psoriasis on wire poles have become the most annoying advertisements. If you do not classify your customers behind your customers and do not match customers’ needs with products, the information you send will not only play a role, but will also be disgusted with you.
3, price clearance to find old customers?
Are there any coupons with discounts every time? You will think of sending news to old customers quickly. Therefore, customers love small and cheap, low price per passenger, are caused by your own. Still blame you!

There are so many problems, of course, there are a number of reasons. We need to analyze them. Short message, micro-blog, public number are all the way to deliver information to old people. If there is a lack of the most fundamental way to study the way, it is at the end of the day. In our view, there are more important things to do before sending short messages and sending news.
We sum up three major points:
One is the customer’s accurate analysis. This analysis is based on the portrait of the customer. It is a comprehensive insight into the customer’s buying behavior, consumption habits, consumption ability and consumption preference.
Then we divide the value space of customers, then carry out group management, and accurately match products for different customers. At this stage, we also need to predict customer churn, and the next step will be much easier.
The first two steps are well done, and now we will develop targeted maintenance and marketing programs to accurately grasp the marketing rhythm. With the work behind these, is it more accurate to send text messages and send messages again?

Do not say that I do not practice, these seemingly simple things, we are through many service experience summed up.

What is a double head stud

The diameter, length and quantity of the stud studs should meet the requirements. The type and material of the stud studs should be determined by grade. There are two commonly used stud studs (also called full threaded studs), two kinds of thread and fine teeth. The common thread of the rough teeth is expressed by M and nominal diameter. The common thread of the fine teeth is expressed by M and the nominal diameter of the screw. The fasteners standard stipulates that the bolts for M36 are coarse teeth, and M36 and above diameters can be made of fine thread, with pitch of 3.
Bm=1d double head stud is generally used for the connection between two steel joints; bm=1.25d and bm=1.5d stud studs are generally used for the connection between cast iron and steel connected parts; bm=2d double head studs are generally used for connection between aluminum alloy and steel connected parts. The preceding connector has an inner threaded hole, and the latter connector has a through hole. The two ends of the equal length stud stud should be matched with nuts and washers for two connecting pieces with through holes.
Double headed stud
One end of the welded stud is welded on the surface of the connector, the other end (threaded end) passes through the connecting piece with the through hole, then the gasket is put on, and the nut is wrung, so that the two connected parts are connected to a whole.

A man has gone through the rain to see the Guanyin umbrella. Guanyin said, “in the rain you are under the eaves, there is no rain under the eaves, you do not need it.” The man jumped out of the eaves and stood in the rain: “now I am in the rain, Bodhisattva”, “Guanyin said,” I am not caught in an umbrella because I am not myself, but I am an umbrella. You should find your own umbrella! “
Life is not always the eight or nine. If you live in this world, you will inevitably encounter some big or small ones. In the difficult position, how to get rid of, the most critical point is to have a heart of self.
Think carefully about how many times you once thought of a desperate situation as if you had gone through the clouds and gone with the wind. Life can’t be as good as you think, but it will not be as bad as you think. In your lifetime, your weakness and strength often exceed your imagination. Sometimes, you may be vulnerable to tears. Sometimes, I found myself walking a long way through my teeth.
See the rainbow after the wind and rain
Life is not about falling down, but running up and running. In the face of frustrations, the best way to live is to wait for the time to let nature take its course and to surpass yourself in quietness. As Zeng Guofan said, “knowing the sky is long and I am short of experience, I will turn my back on it, and I will wait for it.”
The real practice of life is to be honest and true, not to drift along or rely on others. Asking for help is better than asking yourself. You can only measure yourself when you are in trouble. Remember: before giving you the crown of success, luck will test you with adversity and see if your endurance and courage are enough.

Qualitative changes in the emergence of liquid nitrogen freezers

With the advancement of urbanization, people’s lives are becoming more and more fast. Frozen food is one of the products that are heated and ready to eat, and its market share is increasing year by year. At the same time, the development of refrigeration equipment such as liquid nitrogen quick freezing machine for frozen food production is also particularly important.

Frozen food is not only a single product, such as dumplings, dumplings, steamed bun, steamed bun, hot pot food and so on, but also a variety of frozen semi-finished snacks such as hand grab cake and egg tart. In addition, fast frozen meat products, seafood and fruits and vegetables are also an indispensable part of frozen food.

In the Tenth China frozen food industry conference, experts predict that in the next 5 years, China’s frozen food sales will usher in a blowout period. The output value of quick-frozen flour products is about 40 billion yuan in 2013, and the compound annual growth rate of production and sales is expected to be over 13% in the next 5 years. Chen Zhenjie, the chief engineer of the Henan provincial industry and information office, said, “when the urbanization rate of a place exceeds 50%, the frozen food in the region will increase.”

According to the author’s understanding, in the past 20 years, China’s frozen food industry has experienced a period of rapid development from scratch, from less to more, and also led to the rise of raw materials, processing machinery, refrigeration equipment and other industries. As the state supervision of environmental protection is becoming more and more strict, some of the refrigeration equipment that are not compatible with the environment are dropping out, and the emergence of the liquid nitrogen freezer has undoubtedly brought about a qualitative change to the development of the fast frozen food industry, with the necessary freezers in the production process of frozen food. In the future, in the booming development of frozen food industry, refrigeration equipment such as liquid nitrogen quick freezing machine will also usher in an opportunity for development.

As we all know, the development of aviation and military affairs has produced many high-tech products, which eventually serve the production and life of mankind. In the 50s of last century, the development of space technology was needed, which made the industrial process of air liquefaction and separation quicker, and the liquid nitrogen was also industrialized at this time, which laid the foundation for the later application of the food fast freezing industry.

In the 60s of last century, liquid nitrogen quick-frozen technology was first developed in the American frozen food industry and promoted. According to the rapid professional staff in Guangzhou, the liquid nitrogen freezer and the production line not only have small area, but also have rapid refrigeration and little damage to the food itself. It can guarantee the original flavor of frozen food to the greatest extent.

Compared with developed countries such as the United States, China’s liquid nitrogen rapid freezing technology started 10 years late. In the early 70s of last century, China has developed a liquid nitrogen quick frozen food production line. With the development of the society, the demand for the taste and nutrition of the frozen food has been improved continuously. The traditional ammonia food freezer has been unable to meet the demand of the market, and is replaced by a more dominant liquid nitrogen freezer. Indeed, the liquid nitrogen quick freezing machine has an unparalleled advantage in the food refrigeration effect. The seafood treated with liquid nitrogen quick freezing technology, the taste and color after thawing are almost the same as living, and well lock the original water of the seafood. It has high quality and low loss for the operators. In the past, seafood frozen by freezing technology not only failed to reach the requirement of high quality, but also had serious loss of water after thawing. In addition, the original freezing technology because the freezing time is too long, resulting in the further reduction of the quality of food, liquid nitrogen quick freezing technology can achieve rapid cooling in a relatively short time, the maximum degree of preservation. RDH6S0$([RNKP7F@5Q%_SNJ_ Iqiyi)
The advantage of liquid nitrogen quick freezing technology is obvious, and it is widely applied in the large demand of frozen food market in China. With the development of science and technology and the innovation and development of the refrigeration equipment enterprises, the liquid nitrogen quick freezing machine has made great progress in the development of our country, and can make the equipment more in line with the characteristics of different food. Guangzhou speed refrigeration equipment Co., Ltd. mainly deals with liquid nitrogen quick freezing equipment and liquid nitrogen frozen tunnel production line. The equipment structure is diversified, including box type, cabinet type, tunnel type and combination type. It can meet the requirements of seafood, meat products, rice noodle, fruit and other different products and different production speed, and has high safety performance, energy saving and environmental protection.

After more than 20 years of development, the frozen food industry has become the “gold industry” in China’s food industry. In the future, with the continuous growth of consumer demand, China’s fast frozen food industry will soon usher in a blowout period. The rapid development of the frozen food market has driven the demand for refrigeration equipment, especially in the liquid nitrogen quick freezing machine market of quick freezing equipment.

At present, with the efforts of absorbing foreign experience and strengthening independent innovation, the technology and equipment performance of liquid nitrogen quick freezing equipment in our country have improved to meet the basic needs of the domestic market. But in some core technologies, it also relies on foreign countries, which is not conducive to the long-term development of the industry. The refrigeration equipment enterprises should recognize the strong demand of the domestic quick frozen food market for the high quality liquid nitrogen quick freezing machine, and should also clearly understand the insufficiency of their own strength. At present, many enterprises can produce their own equipment to meet the domestic market, but the technology is stagnant. Consumers will surely choose products with better performance. WeChat picture _20180425112018_ Iqiyi
At present, the domestic food market is facing the upgrade of consumption, whether it is to buy food, or purchase equipment, consumers are less sensitive to the price, and pay more attention to quality. Guangzhou speed refrigeration equipment Co., Ltd. is a high-tech enterprise integrating R & D, production and sales.

How to do the routine cleaning of stainless steel mesh belt

No matter what products are used for a long time, there will be more or less dust or other foreign matter. In the longer use of the process, it is unavoidable to mix with some materials to transport the residue, more difficult to clean up, especially the stainless steel mesh belt in food machinery, for a long time will produce pollution to the food, so how do we do the daily cleaning of stainless steel mesh belt?
1, brush type cleaning is through the brush and the direct touch of the water material, so that the material surface of the dirt brush clean, this cleaning method is often used to produce stainless steel mesh belt of potato, radish and other root vegetables.
2, high pressure sprinkler cleaning is mainly based on the high pressure water from the sprinkler head to remove the impurities that are attached to the surface of the stainless steel mesh belt.
3, the roller conflict cleaning is to sink the lower part of the roller in the water, and the material is placed in the screen type roller. With the roller rolling, the material and the material will be clashed, so that the surface of the material is removed and clean.
4, bubble cleaning is to make air into the water, constantly stir the clean water and produce a large number of bubbles, in the appearance of the cleanser, the effect of cavitation, which will be cleaned and cleaned.
5, ultrasonic cleaning is a million small vacuum bubbles in the liquid. These bubbles burst in a large number of bubbles under the sound pressure, and they constantly explode strongly, emit strong pressure and negative pressure, and make the dirt out of the body’s appearance, and the cleaner will not have physical damage. Whether this method can be used to clean vegetables is not known, because whether ultrasonic will have adverse effects on vegetables needs further study.

Introduction of drawing machine equipment

One, model.
Commonly used plastic suction machine models are single head thick film plastic suction machine and double station plastic suction machine two kinds. According to the comprehensive cost performance and popularization rate, the double station plastic suction machine is a more choice model for luggage manufacturers.

Two. The size of the machine.

A suitable suction machine is a good sucking machine. The model of the pull rod box in the market is 20 inch, 22 inch, 24 inch, 26 inch, 28 inch, 30 inch. How do you choose the machine with so many sizes? In fact, just choose the machine according to the larger size. In conventional 28 inches, the size of the machine is 680*960 (unit: mm), and the larger luggage is 30 inches with more than 1 meters.

Three. Cost performance

The price of the draw bag machine is different according to the size of the machine, the size of the machine and the configuration. Common price range is 100 thousand -20, high price may be high, generally more than ten thousand.

The quality of the environment directly affects the efficiency and stability of industrial water chillers.

The better the working environment of chillers is, the more stable the running efficiency of the chillers is when they operate the chillers. If the enterprise wants to use the least cost to complete the operation of the chiller, it is necessary to carefully select the suitable installation environment before installing the chiller. The installation position suitable for the operation of the air-cooled cold water machine can avoid the failure of the cold water machine, endanger the normal operation of the cold water machine, and even affect the cost of the enterprise to use the cold water machine.

The safety of equipment is directly related to the location of installation and the installation environment. When installing the cold water machine, it is necessary for the enterprise to use the professional installation personnel to complete the safety process of the cold water machine, and choose the dry running environment when choosing the installation position. If the running environment of the cold water machine is too wet, it directly affects the service life of the cold water machine, causes corrosion of the equipment and so on. Barrier. The better the environment of chiller, the longer the life of the equipment.

What basic environment does the chiller need to provide for the equipment?
1, when installing chillers, you need to choose the location of clean and clean operating environment to install chillers. Because the air-cooled and water-cooled chiller has higher environmental requirements, any harsh environment will affect the operation safety and stability of chillers. It can prolong the service life of chillers and reduce the expenses of chillers.

2, good operating environment can maintain good cooling performance of the cooling water machine. Because the high temperature seriously affects the safety and stability of the operation of the chiller, it can pick up the cooling water machine with stable ventilation and can handle the heat in time. The lower the temperature of the chiller running environment, the lower the probability of equipment failure.

When the cold water machine is used daily, if it can provide the suitable operating environment for the equipment, and when the cold water machine is used, as much as possible to provide a comfortable operating environment for the cold water machine, then the chiller can maintain more stable operating performance. The better the operation environment of the industrial water chiller, the lower the maintenance cost of the later consumption, and meet the stringent requirements of the enterprise for the low temperature environment at the lowest cost.
