Linear motor-driven plunger pump
InactiveCN102305203AReduce in quantityImprove anti-pollution performancePumpsPositive-displacement liquid enginesPermanent magnet rotorReciprocating motion
The invention relates to a linear motor-driven plunger pump. The mechanical part of the plunger pump comprises a cylinder body I, a cylinder body II, flow distribution valves, an in-sucking communication pipe, out-pressing communication pipes, compacting flanges, plunger rods, linear motor stators, linear motor rotors and guide rails; and the electric part mainly consists of linear motors, a controller, drivers and a position feedback device. The linear motor-driven plunger pump is characterized in that a group of coil-type stators drive a permanent magnet rotor in a combinational way, thus realizing high thrust output of the linear motors. Each flat-type linear motor drives two plungers at the two ends of one plunger rod, and while the double-action plunger rod reciprocates, one end of the double-action plunger rod sucks water and at the same time the other end of the double-action plunger rod presses water. The two cylinders realizes the effective communication between the water sucking loop and water pressing loop of the plunger pump by means of the in-sucking communication pipe and the two out-pressing communication pipes. Each plunger hole is communicated with a flow distribution valve consisting of an in-sucking valve and an out-pressing valve. The electric part controls the out-of-phase movement of the linear motors, thus ensuring the stable combinational flow output of the pump. The linear motor-driven plunger pump disclosed by the invention has the advantages of less mechanical transmission links and high system efficiency and reliability.
