With the rapid development of engineering equipment in our country, more and more machines are developing.
Due to the necessity of pressure relief of machinery and equipment, the valve of screw air compressor plays an important role in the whole process of maintenance of machinery and equipment.
What is the detection method of screw air compressor valve?
1. Offline calibration of calibration platform:
It is to install the screw air compressor valve on the calibration table, and then use the calibration material to open the valve. Carefully observe the barometer to determine the open working pressure.
However, this kind of method can not fully consider the calibration of condensing valve and high temperature or ultra-low temperature material safety valve.
2. Online instrument calibration:
According to the external force, the elastic yellow interaction force on the valve can be measured to calculate the opening working pressure of the valve. Generally, this kind of method does not harm the production and manufacturing, and the working pressure of the system software does not need to be changed. The inspection speed is relatively fast and convenient, but this method can not test the sealing characteristics of the valve 。
The screw type air compressor valve is installed in the system software, and the system software changes the pressure by human factors until the valve jumps up to observe the opening working pressure of the valve. This kind of calibration method will cause great damage to the protruding surface of the valve, and the actual operation risk factors are also relatively large.
