Pneumatic Pressure Testing Equipment

The pneumatic pressure testing equipment uses compressed air as power source for the pneumatic pump which supplies hydraulic pressure for hydraulic pump tester, with the hydraulic output pressure of the pump proportional to the compressed air pressure. By adjusting air source pressure, corresponding hydraulic pressure is obtained. When a balance is reached between compressed air pressure and hydraulic pressure, the air powered pump stops pressure charging and the output hydraulic pressure is stabilized at the preset level.

 

The Important of Pneumatic Pressure Testing Equipment


The pneumatic pressure testing equipment we provide plays an important in the high pressure testing device, which can effectively help engineers find equipment problems and improve the reliability and safety of the equipment. High pressure test unit equipment usually includes transformers, switchgear, circuit breakers, etc. These equipment will generate high voltage and high current during operation, so they need to undergo strict testing and inspection to ensure their reliability and safety. In these tests, air pressure testing equipment is mainly used to test the sealing performance and pressure resistance of the equipment.

Oil drilling application scenarios

 

​Pipe and valve testing: In oil drilling, drilling pipes and valves must be able to withstand high-pressure environments. Pneumatic pressure testing devices are used to test these critical components to ensure they can safely and reliably withstand high pressures in actual operation.

Wellhead equipment testing: Wellhead equipment, such as wellhead valves and blowout preventers, need to work under high-pressure conditions. By using pneumatic pressure testing devices, operators can verify the performance of these devices in high-pressure environments and detect potential problems.

Downhole piping systems: Pneumatic pressure testing devices can be used to test the tightness and stability of downhole piping systems. This is critical to ensuring that the piping system from the bottom of the well to the surface does not leak during drilling operations.

Blowout prevention system testing: To address the risk of blowout, blowout prevention systems are often used in oil drilling. Pneumatic pressure testing devices are used to verify the performance of blowout prevention systems to ensure that eruptions can be stopped quickly and effectively when needed.
