Problems solved by technology

[0003] The electronic components in its drive circuit do not dissipate heat well and are easily damaged by heat
[0004] The heat dissipation of the coil is not good, and it is easy to age due to overheating
Its heat dissipation is mainly carried out through heat conduction to the air around the coil, the heat dissipation effect is not good, and the temperature rise of the coil is very high, which can reach above 120°C
Excessive temperature aggravates the aging of the coil, and at the same time heat is transferred to the electronic components of the drive circuit board, and the electronic components are damaged by heat

Abstract

The invention discloses a plunger pump comprising a pump casing assembly, a moving assembly, a magnetic path assembly, a drive circuit and a connecting screw. The plunger pump is characterized in that an oil inlet cavity (1) of the pump casing assembly, a valve (2), a runner of a valve seat (6), an inner hole and a valve of a plunger (7) of the moving assembly, a runner of a magnetic path end cover (13), a coil gap and an oil outlet cavity (8) of the pump casing assembly form a one-way path by pushing the valve under the hydraulic action; the coil and other power devices are soaked in a medium to be conveyed; and the effect for cooling on the coil and other power devices can be generated by using the flowing of the medium to be conveyed to take away the heat. Compared with the other plunger pumps, the plunger pump has the advantages of favorable heat dissipation and high reliability.

Description

1. Technical field [0001] The patent of the present invention relates to a device for transporting insulating fluid using direct current as a power source, in particular to a plunger pump for transporting fuel oil which has high requirements on reliability. 2. Background technology [0002] At present, plunger pumps are widely used in pumps that use direct current as a power source, and pulses are generally used to drive coils, so that the coils generate pulsed magnetic fields to attract "working pieces" to produce actions. It has the advantages of small size, light weight, and convenient installation, but it has the following disadvantages: [0003] The electronic components in its drive circuit do not dissipate heat well and are easily damaged by heat. [0004] The heat dissipation of the coil is not good, and it is easy to age due to overheating. Its heat dissipation is mainly carried out through heat conduction to the air around the coil, the heat dissipation effect is...
