Pneumatic Oil Pump Working Principle

1. Compressed air enters through the filter 14, pushing the selection valve 2 down, and then the gas enters the cylinder block through channel B to push the piston 7 down. The piston 17 connected with the piston 7 acts with the piston at the same time. The piston presses the oil in the chamber through the one-way valve R to the outlet.

2. When the plunger drops down, select valve 2 to close and prevent compressed air from entering the cylinder body, then relies on the spring 10 in the cylinder to overcome the pressure and push the piston up. The plunger also rises. At this time, the suction one-way valve 24 opens and sucks oil into the chamber. The gas is discharged from the muffler 12 through channels A and B.

3. When the plunger rises to the upstream, the selection valve opens again, and compressed air pushes the plunger to discharge oil.

4. In the absence of load, repeat the above 1-3 actions at a high frequency of about 2000 strokes per minute until the pressure and oil pressure are stable. When the pressure of both is constant, the circulation of the pump will stop automatically. If the pressure of the hydraulic circuit drops unexpectedly, the pump will operate automatically as long as the compressed air is supplied for a long time, until the oil pressure reaches a constant again.
