Problems solved by technology

Since the plunger needs to move back and forth in the pump body to increase the hydraulic pressure, it is necessary to reserve enough stroke space for the plunger when designing the plunger pump, so that the hydraulic pressure value is proportional to the volume of the plunger pump. If the hydraulic pressure to be provided is greater, the volume of the plunger pump will be larger. When ultra-high pressure needs to be provided, the volume of the plunger pump will be quite large, which will increase the manufacturing cost and be extremely inconvenient to use.
In addition, the flow rate and pressure supplied by the existing plunger pumps are fixed. It is difficult to find a plunger pump with the required pressure during production and use. If the plunger pump with lower pressure is selected, it cannot be used normally. High pressure will cause waste of hydraulic power, so it is not easy to choose a plunger pump that matches the required pressure

Abstract

The invention discloses an ultrahigh pressure radial plunger pump, and belongs to the technical field of hydraulic control. The ultrahigh pressure radial plunger pump comprises a motor which is arranged on a bearing framework, an eccentric shaft is sleeved on an output shaft of the motor, multiple sets of plunger pumps are evenly distributed on the periphery of the eccentric shaft, the multiple sets of plunger pumps with the output shaft of the motor as the center, a conical roller bearing is sleeved on the eccentric shaft, and the outer ring of the conical roller bearing simultaneously contacts with the top ends of the multiple sets of plunger pumps with the output shaft of the motor as the center. The ultrahigh pressure radial plunger pump can achieve variable pressure and variable flow, the multiple plunger pumps can be in parallel connection, oil mass supply of a large-scale hydraulic pressure station is satisfied, sealing performance is good, service life is long, reliability is high, performance cost ratio is high, and the ultrahigh pressure radial plunger pump is suitable for application and popularization.

Description

technical field [0001] The invention relates to a plunger pump, in particular to an ultra-high pressure plunger pump. Background technique [0002] The plunger pump is a pump that uses the plunger to reciprocate in the pump cylinder to change the volume between the plunger and the pump wall, repeatedly sucks and discharges liquid and increases its pressure. Since the plunger needs to move back and forth in the pump body to increase the hydraulic pressure, it is necessary to reserve enough stroke space for the plunger when designing the plunger pump, so that the hydraulic pressure value is proportional to the volume of the plunger pump. If the hydraulic pressure to be provided is larger, the volume of the plunger pump will be larger. When ultra-high pressure needs to be provided, the volume of the plunger pump will be quite large, which increases the manufacturing cost and is extremely inconvenient to use. In addition, the flow rate and pressure supplied by the existing plun...
