Abstract

The invention discloses a linear drive plunger pump, a system and a control method. The linear drive plunger pump comprises a rack, a stator, a mover, a suction and drainage valve assembly, two hydraulic plunger type cylinders and two hydraulic plungers. The stator is fixed to the rack. The mover is contained in the stator. The mover is capable of doing linear reciprocating motion in the stator. The hydraulic plunger type cylinders are arranged on the two sides of the rack. The suction and drainage valve assembly is arranged on one of the hydraulic plunger type cylinders. The suction and drainage valve assembly communicates with inner cavities of the hydraulic plunger type cylinders. The hydraulic plungers are contained in the hydraulic plunger type cylinders. The two ends of the mover areconnected with the corresponding hydraulic plungers. According to the linear drive plunger pump, the linear drive emulsion pump system and the control method, the electromagnetic linear transmissionmethod is adopted for driving the mover, the hydraulic plungers are driven by the mover to do reciprocating motion in the inner cavities of the hydraulic plunger type cylinders, and constant-pressurelow-pulse liquid supply is achieved.

Description

technical field [0001] The invention relates to the related technical field of emulsion pumps, in particular to a linear drive plunger pump, a linear drive emulsion pump system, and a control method. Background technique [0002] At present, in the production process of fully mechanized coal mining, the hydraulic power source of the emulsion pump station, one of the main equipment, uses an electric motor to drive the crankshaft connecting rod mechanism through gear transmission, driving the slider and the plunger connected to it to reciprocate, through The suction and discharge valve supplies liquid to the hydraulic system of the fully mechanized mining face. [0003] The traditional crank-connecting rod emulsion pump, because of its intermediate kinetic energy transmission mechanism, produces a series of adverse effects such as moment of inertia, elastic deformation, backlash, movement hysteresis, friction, vibration, noise and wear, which reduces the efficiency of the emul...
