📘 Product Description
The pneumatic hydraulic test bench uses pure compressed air as the driving power source, liquid booster pump as the pressure source, and water, hydraulic oil and other liquid as the pressurized medium. The output pressure is proportional to the driving gas pressure. By adjusting the pressure of the driving gas source, the corresponding pressure of the pressurized liquid can be obtained. When the pressure of the driving source is balanced with that of the pressurized liquid, the pneumatic booster pump will automatically stop and the output liquid pressure is stabilized at the preset pressure.
It features an explosion-proof design, energy saving, environmental protection, and adjustable output pressure. The equipment is assembled in a closed stainless steel cabinet or frame. The pressure gauge, valve, and pressure regulator are mounted on the panel with clear markings for easy operation.
📊 Product Parameters
Pumps feature a large air piston joint to a smaller diameter piston. The pressure ratio determines the maximum outlet pressure. The outlet pressure is easily set through a simple regulator. Principle of operation is similar to a reciprocating amplifier.
