What is a positive displacement pump? He Weizheng displacement?
Includes a pump housing (10), a pump chamber (24), the pump chamber has an entrance channel (21) and an outlet check valve (17) export control channel (28), a displacement member (13), the definition of the pump cavity in a direction of movement in (24) and in a stroke section in the pump cavity (S) in reciprocating motion
The principle and structure of displacement pumps are similar to those of hydraulic motors. Positive displacement is the pump outward to provide flow and pressure, that is, conventional pumps. A negative displacement pump is a hydraulic motor that rotates by external pressure and flow
And includes a pump chamber (24) to open and a channel is arranged between the entrance and the pump chamber (26) in the second one-way valve (15), and one for the continuous displacement member (13) in the pump shell (10) in the travel section (S) actuating mechanism reciprocating motion.
The principle and structure of positive displacement pumps are similar to those of hydraulic motors. Positive displacement is the pump outward to provide flow and pressure, that is, conventional pumps. A negative displacement pump is a hydraulic motor that rotates by external pressure and flow.
