Abstract

The invention discloses a plunger pump driven by a linear motor. The plunger pump is driven by the linear motor, and a motion rule of an assembly is controlled by controlling a motion rule of the linear motor, so that the disadvantages of an existing plunger pump are overcome, and the advantage of the plunger pump is exerted to the maximum extent.

Description

technical field [0001] The invention relates to the technical field of plunger pumps, in particular to a plunger pump driven by a linear motor. 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 fluct...
