Embodiment Construction

[0018] The present invention will be described in detail below in conjunction with the accompanying drawings.

[0019] refer to figure 1 , a fully balanced double-row radial piston pump, including a pump body 7, a front end cover 3 on the left side of the pump body 7, and a rolling bearing 15 pressed inside the front end cover 3, the rolling bearing 15 is installed on the eccentric shaft 14, and the positioning sleeve 1. It is located inside the rolling bearing and close to the side of the eccentric part of the eccentric shaft 14. A rolling bearing 12 is installed outside the eccentric part of the eccentric shaft 14. The rolling bearing 12 is connected with the uniformly distributed plungers 8 through a coupling mechanism. The plungers 8 are arranged in double rows. There is a suction system in the middle of the row of plungers, and a discharge system on the other side of each row of plungers. The plunger 8 is located in the plunger chamber 30. The pump body 7 is equipped with...

Abstract

The invention discloses a fully-balanced type double-row radial plunger pump. A rolling bearing is arranged on the outer part of an eccentric part of the plunger pump; a pentagonal wear resistant sleeve is arranged on an outer ring of the rolling bearing; a groove is formed on the side face of the pentagonal wear resistant sleeve; a cylindrical roller is arranged in the groove; the outer side of the roller is contacted with the end of a plunger; a plunger cavity is communicated with a suction valve and a discharge valve respectively; the suction valve is designed by an external structure of areturn spring, so that the internal space of the plunger pump is saved; suction cavities are communicated with one another and discharge cavities are communicated with one another through inclined straight holes respectively to form internal flow channels; the suction cavities and the discharge cavities are communicated with the outside through a single suction inlet and a single discharge outlet; an eccentric shaft is directly driven to rotate through an alternating current servo motor; and fluctuation-free adjustment of output pressure and flow are realized through the servo motor. By the plunger pump, clutches and speed variable gear mechanisms are reduced, the volume and the mass of the pump are reduced, the performance of equipment is improved, and the service life of the equipment is prolonged simultaneously.

Description

technical field [0001] The invention relates to a plunger pump in the technical field of geological drilling, in particular to a fully balanced double-row radial plunger pump. Background technique [0002] At present, the mud pump used in the geological exploration industry is usually driven by a three-phase AC asynchronous motor to drive the clutch, and then the clutch drives the crankshaft to rotate. In order to realize the output of different pressures and flows, a speed change gear mechanism is usually installed between the clutch and the pump body to adjust the speed, which makes the overall structure of the equipment complex, the stability is reduced, the mass and volume are large, and the maintenance is also changed. It's complicated. Contents of the invention [0003] In order to overcome the above-mentioned shortcomings of the prior art, the present invention provides a fully balanced double-row radial piston pump, which reduces the volume and mass of the mud pum...
