Crankshaft Plunger Pump QB21-47-19 | BOP Hydraulic Control Electric Pump
Description
The crankshaft piston pump is a three-plunger pump driven by the crankshaft connecting rod, and the valve is assigned with a flow distribution method. Therefore, the utility model has the advantages of simple structure, convenient maintenance and strong anti-pollution, and is suitable for on-site working conditions. Mainly used in hydraulic oil medium systems. The plunger pump relies on the reciprocating motion of the plunger in the cylinder body to change the volume of the sealed working chamber to achieve oil absorption and pressure.
