Explosion pressure test stand, its pressure test system, in doing airtight test what matters need to pay attention to the following explosion test rig manufacturers Xiaobian to introduce in detail.
Blasting pressure test stand pressure test system
It consists of a compression system and a control and display system. The system is mainly composed of super pressure liquid booster pump and other components, mainly completes the system pressure and pressure, pressure and pressure to ensure long time test. The parameters such as test pressure and step up rate can be set in the test program. After setting the machine can automatically complete, the equipment used for medium water, can the pressure hose, expansion deformation, performance testing, all functions can be tested independently can also be carried out comprehensive test, improve the efficiency of the equipment, and the equipment has the advantages of stable performance, simple operation, convenient maintenance.
Two, gas pressurization system and other air tightness testing device in the test of air tightness matters needing attention
1. for the protection of non pressure monitoring pressure gauge, before the boost, the gas tightness test stand, instrument pressure pipe should be closed.
2. flanges inserted into blind plates for the separation of the system shall be tested with a working medium during the commissioning phase.
3., the pressure should be slow, airtight pressure shall not exceed the specified limit.
4., when the pressure should be as low as possible or low angle of the inverted pour discharge, to avoid effusion.
5. atmospheric pressure system does not do airtight test.
6. the tightness test shall be divided into proper system according to the pressure grade of equipment and pipeline.
7. the pipeline between the system and the system is separated by valves, and separated by blind plates when necessary. The pump bodies are separated by blind plates.
8. the pipeline of the material inlet and outlet device must also be airtight tested.
9. the utility system can conduct airtight test as much as possible by using medium in the pipeline.
