Pressure testing machine powered by compressed air, compressed air driven reciprocating fluid pneumatic pump discharge pressure, pneumatic and hydraulic proportional relations, can be obtained by adjusting the air pressure must be within the scope of fluid pressure. When the air force and the hydraulic force balance pneumatic pump stop, output liquid pressure is stable in the preset value.

Control the compressed air into the air would be controlled drainage quantity, and pressure testing machine with adjustable output liquid pressure, the characteristics of the pressurized speed control. At the same time with a simple direct, avoid the hydraulic impact is characteristic of the specimens.

Well control equipment used in oil drilling engineering of the bop stack, throttle manifold, casing head, pipe, valve parts, or other pressure parts of the hydraulic pressure test.

Pressure testing machine by the pressure testing machine main body and pressure pipe fittings (see test fitting table 2). Pressure testing machine main export cut-off valve hydraulic circuit by the fuel tank, fuel tank, water inlet valve, filter, pneumatic pump, single valve, safety valve, primary secondary pneumatic pump, high pressure cut-off valve, three-way cock and other components; Pneumatic circuit consists of air valve, air filter, air pressure regulating valve, oil mist device, pneumatic pump pneumatic cut-off valve components, etc.

Hydraulic test pump recorder can choose disc type, electronic, digital type main and acquisition card.
