1, "spindle clearance compensation" design, according to the set pressure, automatically adjust the pump displacement.
2, built-in pressure adjustment valve, the system does not need to install a regulator.
3, suitable for grinding machine, automatic lathe, masterbatch machine, shoe machinery and other mono-capable machines.
4, easy to assemble, can be directly combined with the motor oil pump.
Piston pump work, in the injection pump camshaft cam and plunger spring action, forcing the plunger for up and down reciprocating motion, so as to complete the pumping task, pumping process can be divided into the following three stages. Plunger upward oil supply, when upward to the plunger on the oblique groove (stop supply side) and the sleeve on the oil return holes connected, the pumping chamber pressure oil circuit will be with the plunger head of the center hole and radial holes and the oblique groove communication, oil pressure suddenly drop, the oil valve in the action of the spring force to close quickly, to stop supplying oil. This plunger also want to go up, when the cam's raised part of the turn over , under the action of the spring, the plunger and go down. At this point, the next cycle will begin. Piston pump service life length, and the usual maintenance, the quantity and quality of hydraulic oil, fluid cleanliness and so on. Avoid particles in the fluid on the piston pump friction vice wear, etc., is also an effective way to extend the life of the piston pump.
