Problems solved by technology

This kind of rotary drive plunger pump has the following problems: the traditional rotary drive plunger pump has many intermediate transmission links, high friction and wear, and low system efficiency; the structure is complex, the manufacturing process is difficult, the cost is high, there are many vulnerable parts, and failures occur The probability of high risk is high, and maintenance is inconvenient; the plunger speed varies greatly, the displacement of the plunger pump fluctuates greatly, and the discharge pressure is unstable; limited by the structure of the power end of the traditional crankshaft connecting rod, it is difficult to achieve long stroke, low stroke frequency, and large discharge High-volume operation requirements; complex structure, large friction and wear, and large pressure fluctuations, resulting in low service life of wearing parts and serious vibration and noise during operation

Abstract

The invention discloses a linear motor plunger pump. The plunger pump is driven through a linear motor, the movement rule of an assembly is controlled by controlling the movement rule of the linear motor, and therefore the defects of an existing plunger pump are overcome, and the advantages of the plunger pump are furthest developed.

Description

technical field [0001] The invention relates to the technical field of plunger pumps, in particular to a linear motor plunger pump. Background technique [0002] Traditional plunger pumps generally change the rotary motion of the prime mover into linear reciprocating motion of the plunger through the crank linkage mechanism, so that the liquid is intermittently sucked into the pump cylinder and discharged from the pipeline at high pressure to achieve the purpose of conveying the liquid. This kind of rotary drive plunger pump has the following problems: the traditional rotary drive plunger pump has many intermediate transmission links, high friction and wear, and low system efficiency; the structure is complex, the manufacturing process is difficult, the cost is high, there are many vulnerable parts, and failures occur The probability of high risk is high, and maintenance is inconvenient; the plunger speed varies greatly, the displacement of the plunger pump fluctuates greatl...
