Embodiment Construction

[0032] In the existing plunger pump, the pump oil volume of the plunger assembly is very small. When a hydraulic tool needs a large flow, the motor needs to increase the speed to increase the pump oil volume. The high-speed operation of the motor makes the heat generation very large and the increase in the flow is not ideal. In view of this, the present invention provides a large-flow radial multi-piston oil pump device.

[0033] The large-flow radial multi-plunger pump oil device provided by this embodiment includes a housing 1, a drive assembly 2, a plunger valve body 3, at least five plunger assemblies 4, and a connecting part. The drive assembly 2 is fixed to the housing 1, and the drive assembly 2 includes a motor assembly 21 and an eccentric assembly 22. The plunger valve body 3 is arranged in the housing 1. The plunger valve body 3 has a mounting hole 301 in the middle, and the eccentric wheel assembly 22 extends into the mounting hole 301. The plunger valve body 3 includ...

Abstract

The invention provides a large-flow oil pumping device with multiple radial plunger pistons. The large-flow oil pumping device with the multiple radial plunger pistons comprises a shell body, a driving assembly, a plunger piston valve body, at least five plunger piston assemblies and connecting parts. The driving assembly is fixed into the shell body; the plunger piston valve body is arranged in the shell body, an installing hole is formed in the middle part of the plunger piston valve body, and an eccentric wheel assembly stretches into the installing hole; the plunger piston valve body comprises at least five plunger piston installing parts arranged in the circumferential direction and distributed uniformly, every plunger piston installing part is provided with a radial plunger piston hole, an oil inlet hole and oil outlet holes communicating with the radial plunger piston hole, and every radial plunger piston hole is internally provided with a assemble boss. At least five plunger piston assemblies are correspondingly installed in at least five radial plunger piston holes and in contact with the rotating eccentric wheel assembly, and every plunger piston assembly comprises an oilsliding switch. Each of the connecting parts is formed on the every assemble boss and protrudes towards the side which the every oil sliding switch located on, or each of the connecting parts is formed on the every oil sliding switch and protrudes towards the side which the every assemble boss located on, and the area of each of the end faces of the free ends of the connecting parts is smaller than the area of the step face of the every assemble boss.

Description

Technical field [0001] The invention relates to a hydraulic pump assembly, and in particular to a large-flow radial multi-piston oil pump device. Background technique [0002] Oil pump device refers to a device that obtains power from the power take-off of the engine or gearbox through the oil pump, and then transmits hydraulic power to the actuator through the oil pump. The operation quality of the oil pump device is related to the performance of the actuator. Once the design of the operating mechanism of the oil pump device is unreasonable, some failures will occur, such as cylinder explosion, oil leakage, pressure transmission component fracture, oil pressure generating component jam or disconnection. As an important part of the oil pump assembly, when the oil pump device fails, it is very likely to cause damage to the related supporting parts, which greatly increases maintenance costs and replacement costs. [0003] The current high pressure oil pump plunger pump has a small ...
