Some common problems you may encounter in the service life of diaphragm pressure gauge.

In the service life of diaphragm pressure gauge, you may encounter some common problems of diaphragm pressure gauge. Unfortunately, no matter how you maintain it, almost every diaphragm pressure gauge needs to be repaired from time to time. Fortunately, you can take many measures to prevent problems with diaphragm pressure gauges and deal with them quickly when problems occur. One way to prevent problems is to ensure that the diaphragm pressure gauge is adjusted at least once a year. During this time, your diaphragm pressure gauge service professionals can ensure that yi is cut normally, replace the air filter, and find any problems that may occur in the production line. Like many things, yu prevention is the key in the maintenance of diaphragm pressure gauges.

Easy solution or a bigger problem?

There are many different types of diaphragm pressure gauges. Maybe the house is not cooled to the set temperature, or you are dealing with unbalanced cooling methods. To some people, this seems to be a small problem, but you won't know whether the cause is benign until the service professional looks at your machine, such as dirty air filter or worse. In fact, many common problems with diaphragm pressure gauges will have similar effects, so it is very important to check the diaphragm pressure gauges as soon as possible.

Besides, even a small problem may soon become a big problem. If the air flow is blocked or misled by the air duct system, the components in the diaphragm pressure gauge will be much more difficult than they need, and may be broken. Knowing some common problems of diaphragm pressure gauge can help you find the problems before they get worse.

So what problems may you encounter with diaphragm pressure gauges? The following are three common problems of zui:

The diaphragm pressure gauge is closed before a full cycle: For some reasons, your diaphragm pressure gauge may not be able to run for a full cycle before it is closed. Usually, this problem is caused by dirty or wet parts. This may also be a sign that you have a vibration pressure gauge with great resistance to chao. If your equipment is too big, its cooling speed will be too fast, and zui will eventually make your electricity bill expensive.

No cold air: If your equipment seems to be working, but there is no cold air flowing out, there may be something wrong with the refrigerant. You may have a refrigerant leak or just need to add more. Diaphragm pressure gauge service professionals can check for you.

Uneven cooling: If your diaphragm pressure gauge only cools some rooms or looks unbalanced, it may be caused by dirty air filter, component problems or even unbalanced diaphragm pressure gauge. Your local diaphragm pressure gauge professionals should be able to diagnose the problem and give a good solution to zui.

What is the elastic aftereffect of stainless steel shock-resistant meter?

1. Inelastic effect and elastic aftereffect of elastic elements of stainless steel seismic table. It means that when the pressure exerted on the elastic element is cancelled, the original shape and size cannot be restored immediately, but it will take some time for the elastic element to return to its original shape and size. This phenomenon is called elastic aftereffect.

2. Proportional limit and elastic limit of stainless steel seismic table. The proportional limit is illustrated by taking low carbon steel and stress-strain characteristic curve as examples. When the relative deformation inside a material increases in direct proportion to the stress, the great stress is called the proportional limit. Elastic limit, under a certain stress, the residual deformation in the material has reached a predetermined small value, then this stress is called elastic limit and expressed by elasticity.

3. The elastic deformation of the elastic element of the stainless steel seismic table, the geometric shape and size of the elastic sensitive element will change under the action of pressure. Within the elastic limit, the change is directly proportional to the pressure. When the pressure is cancelled, the element can return to its original size and shape. This phenomenon is called elastic deformation.

Relevant regulations on pressure gauge verification

1. Why do you want to check the pressure gauge?

After a period of use, the internal parts of the pressure gauge are worn and deformed, which leads to various faults or changes in the value of the pressure gauge, thus losing accuracy and producing out-of-tolerance phenomenon. In order to ensure the accuracy of the pressure gauge and achieve the purpose of correct indication, safety and reliability, the pressure gauge should be periodically verified.

2. The provisions of the pressure gauge verification cycle:

According to the regulation of pressure gauge verification regulation, the verification period of pressure gauge can be determined according to the specific use situation, but generally it should not exceed half a year.

3. What are the requirements for ambient temperature during pressure gauge verification?

Verification regulation of pressure gauge stipulates that:

A. ambient temperature during calibration of precision pressure gauge:

Grade 0.25 is (20 2)℃;

Grade 0.4 is (20 3)℃;

B the ambient temperature for general pressure gauge verification is (20 5)℃;

4. What are the requirements for working medium during pressure gauge verification?

Verification regulation of pressure gauge stipulates that:

The upper limit of measurement is not greater than 0. 25Mpa pressure gauge, the working medium must be air or other non-toxic, harmless and chemically stable gas.

The upper limit of measurement is greater than 0. 25Mpa pressure gauge, the working medium can be liquid, such as transformer oil, medicinal castor oil, glycerol mixture, etc.

5. Provisions on verification points during pressure gauge verification:

The pressure gauge takes the scale line marked with numbers as the verification point.

The pressure part of pressure vacuum gauge shall be verified according to the graduation line marked with numbers; For the vacuum part, the upper measurement limit is 0. Check 3 points at 06Mpa, and the upper limit of measurement is 0. Check 2 points at 15Mpa, and the upper limit of measurement is 0. 3~2。 Check a point at 4Mpa.
