Hydraulic pneumatic valve working principle of the test bed

pneumatic valve testboard is pneumatic valve testing equipment technology according to the country on the basis of GB/T - The general pneumatic valve pressure test and ZBJl - The pneumatic valve testing and detection of standard specification requirements, designed to improve the new generation JWZ type hydraulic pneumatic valve test bed. Set of mechanical and electrical, hydraulic, pressure and liquid medium storage cycle use, with perfect functions, stable performance, high degree of automation, etc. The following is a hydraulic pneumatic valve working principle of the test bed is introduced.
hydraulic pneumatic valve hydraulic, mechanical, electrical, hydraulic test bed set for water pump, the hydraulic oil cylinder pressure. Performance test on subjects of pneumatic valve.
the hydraulic system is the power of this test rig the main source, used for the hydraulic oil cylinder driving and liquid pump function to perform.
the hydraulic oil cylinder compression pressure is adjusted according to the grades of pneumatic valve test pressure different pressure ( The highest hydraulic pressure boost. Mpa。 Compact and reliable, functions meet the size test of pneumatic valve size and class.
for hydraulic pump device with micro pressure and high pressure second gear, in accordance with the test sequence of operation, under the control of the appliances and reduced pressure regulating pneumatic valve, pneumatic valve medium pressure test, for the pump pressure range is. - 。 Mpa for the pressure medium for rust water or oil. Set at the bottom of the storage tank to ensure liquid medium circulation use.
