Reciprocating plunger pump driven by plunger flow distribution double-acting linear motors
The invention discloses a reciprocating plunger pump driven by plunger flow distribution double-acting linear motors. The reciprocating plunger pump comprises a shell, two linear motors, four plungers and four cylinder barrels, wherein the two linear motors and the four cylinder barrels are fixed in the shell; the shell is provided with a pumping outlet and a pumping suction inlet; the plungers and the cylinder barrels are equal in length. During working, linear motor movers are used for driving the plungers to move circularly in a reciprocating way by pulling or pushing in order to complete liquid suction and liquid extruding actions, and the motion difference between the two linear motor movers is a quarter period; the linear motor moves move in a reciprocating way once to complete one working cycle. Compared with a linear motor reciprocating plunger pump adopting a valve flow distribution form, the reciprocating plunger pump has the advantages that plunger flow distribution is adopted, so that the influence of the lag effect of a flow distribution valve is eliminated, and pressure pulsation and flow pulsation are reduced greatly. The plungers in the reciprocating plunger pump are longer than a plunger in a plunger pump driven in a revolving way, and longer gap sealing length is designed on each plunger driven linearly in the reciprocating way, so that leakage can be reduced effectively, and the volume efficiency is increased. 1.
