Product advantages:
Three core parts of safety valve calibration bench equipment
- The main accessories of the equipment (gas, gas-liquid booster pump and high-pressure valve pipe fittings) are all produced by our company independently, and our company is an earlier and larger professional booster pump manufacturer in China. The quality and after-sales service are guaranteed (one year warranty, lifetime warranty), which avoids the problems of delayed after-sales service, shortage of maintenance parts, no warranty and inconvenient maintenance of imported products in some small factories and workshops in China.
- Equipment control system, introduced by our company U.S.A NI The company's data acquisition system and LabVIEW Software The operating system has professional electrical software engineers, which avoids the abuse of rough system pictures in some small factories and workshops, unreasonable design and the use of some cheap proportional valves in the acquisition system
3、 Chuck clamping device. Large clamping force can reach 30T The tightening source is the tightening of the booster pump to avoid the inconvenience of maintenance of the hydraulic station and the defects of messy site.
System characteristics
a) The highly accurate pressure regulating valve regulates the output pressure and manually controls the test process through the button switch on the control cabinet.
b) The pneumatic pressurization technology is used to stabilize and maintain the pressure without fluctuation, and the output pressure is adjustable.
c) The automatic clamping system is convenient for quick installation and positioning of valves.
d) The clamping pressure source adopts a gas-liquid booster pump, which has a large pressure and can automatically supplement pressure to ensure the pressure stability of the system during pressure test and prevent the safety valve from loosening;
e) All high-pressure valves, pipe fittings and joints are three hundred and sixteen Material product, the system adopts solderless connection and cone sealing, which is suitable for the sealing requirements of most hydraulic systems;
f) Ensure the voltage withstand level, safe and reliable, and suitable for most media;
g) The worktable adopts the form of three jaws, and the output force is stable and evenly distributed;
h) use zero point four Class pressure gauge, and provide pressure gauge distribution of different ranges to improve detection accuracy;
i) High quality pneumatic liquid booster pump and pneumatic gas booster pump jointly developed with Germany and imported P arker and SMC High quality pneumatic components, very high pressure valves, pipe fittings, joint quality products.
j) The equipment can be configured with a pressure gauge according to the customer's needs and an external interface is reserved to facilitate the customer to replace the pressure gauge according to the actual measured pressure.
Introduction to system principle
The power source of the equipment is the pneumatic booster pump developed in cooperation with Germany. The booster pump is driven by compressed air. The output pressure of the pump is proportional to the pressure of the driving air. The output pressure can be adjusted steplessly by adjusting the pressure of the driving air. In this system, the electric proportional pressure regulating valve is used to control the output pressure of the pump and the pressure rise rate, It has the advantages of high pressure control accuracy, adjustable output pressure and pressure rise rate. The whole test process can be automatically completed on the computer, and each test parameter can be set freely, such as test pressure, pressure holding time, allowable pressure drop, etc. Automatic pressure relief after test.
