Precautions for pressure testing machine measurement

1. Precautions for pressure testing machine measurement

1. Fixture selection

Fixture selection is very important, as long as you choose the right fixture, you can do a better job. What is a fixture? Fixtures are mainly used on equipment to help equipment measure more accurately. If there is a problem with the clamp, the equipment will definitely be affected in the measurement, accurate data cannot be measured.

2. Check the part problem

When using a pressure testing machine, be sure to check the equipment parts. As long as the equipment parts are firm there are no problems, accurate measurements can be made. However, if there are parts problems during the equipment measurement, the measurement will be useless. Many operators ignore the problem of viewing parts during the measurement process, which often leads to inaccurate measurement results.

3. Pay attention to cleaning

When using a pressure testing machine, we must pay attention to cleaning. Only regular cleaning can ensure the accuracy of the equipment measurement data extend the service life of the equipment. If the operator does pay attention to the cleaning problem, then the equipment measurement will definitely have a greater error.

4. Understand the measurement specifications

Knowing the measurement specification is very important, but it is ignored by many people. For example, the pressure testing machine can only measure metal non-metal materials, while the pressure testing machine manufacturer measures the rubber material, resulting in the inability to obtain data results, at the same time it will cause damage to the equipment. Precautions for pressure testing machine measurement the key to maintenance knowledge of pressure testing machine host

2. Main engine maintenance of pressure testing machine

1. The fixtures of the pressure testing machine should be coated with anti-rust oil for storage;

2. Because the jaws of the hydraulic universal testing machine are often used, they are simply worn too much oxide scale, which will simply cause the small piston to damage leak oil. Therefore, the jaws should be cleaned frequently kept clean (it is best to clean after each test. );

3. The sliding surface of the panel the liner the dovetail groove surface of the liner should be kept clean, a thin layer of MoS2 (molybdenum disulfide) grease should be applied regularly;

4. Check the screws at the jaws regularly, tighten them in time if they are found to be loose;

5. Check the transmission of the sprocket regularly. If there is any looseness, please re-tension the tensioner.
