Hydraulic pump with long service life

Abstract

The invention provides a hydraulic pump with long service life, and belongs to the technical field of hydraulic pumps. The hydraulic pump with long service life solves the problems that a bottom plate of an existing hydraulic pump is extremely prone to vibrating in the operation process, so that a fastening bolt on the bottom plate is loosened, and the stability of the hydraulic pump in use is reduced. The hydraulic pump with long service life comprises a main body, wherein a double-head driving motor is installed on the rear side of the upper end surface of the main body, and a pressure gauge is arranged on the front side of the upper part of the main body; and an auxiliary mechanism is arranged on the front end surface of the pressure gauge. According to the hydraulic pump with long service life, a triangular limiting block at the head end of a first limiting sliding block is matched with a circular bead limiting tooth at the upper end of the fastening bolt, due to the fact that the circular bead surface of the circular bead limiting tooth on the outer circumferential surface of the upper end of the fastening bolt is distributed in a clockwise direction, the fastening bolt cannot rotate anticlockwise at the moment, so that even if the bottom plate of the hydraulic pump vibrates in the operation process, the fastening bolt on the bottom plate of the hydraulic pump cannot be loosened, and then the stability of the hydraulic pump in use is improved.

Description

technical field [0001] The invention belongs to the technical field of hydraulic pumps, and more specifically relates to a hydraulic pump with long service life. Background technique [0002] The hydraulic pump is the power component of the hydraulic system. It is driven by an engine or an electric motor. It sucks oil from the hydraulic oil tank, forms pressure oil and discharges it, and sends it to the actuator. Hydraulic pumps are divided into gear pumps, plunger pumps, vane pumps and screw pumps according to their structure. The hydraulic pump is a hydraulic component that provides pressurized liquid for hydraulic transmission and is a type of pump. [0003] For example, application number: CN201811441270.0 The present invention relates to the technical field of hydraulic pumps, and discloses a hydraulic pump with a long service life, including a hydraulic pump book. The oil discharge is fixedly installed, the fixed external thread is connected with a filter, the interna...

Problems solved by technology

[0005] In order to solve the above technical problems, the present invention provides a hydraulic pump with a long service life to solve the following deficiencies in the actual use of the existing hydraulic pumps, such as: 1. When the existing hydraulic pumps are fixedly installed, generally The bottom bottom plate is fixed by fastening bolts, and the bottom bottom plate of the hydraulic pump lacks an effective anti-loosening structure, so that the bottom bottom plate of the hydraulic pump is prone to vibration during operation, and the bottom bottom plate of the hydraulic pump is in a state of vibration for a long time, thus It will cause the fastening bolts on the bottom floor to loosen, thereby reducing the stability of the hydraulic pump when in use; 2. The pressure gauge on the existing hydraulic pump lacks an effective auxiliary structure. When the light is dark, it is very difficult for people to It is difficult to see the value on the pressure gauge, which reduces the intuitiveness of the pressure gauge on the hydraulic pump; 3. Due to the lack of an effective energy-saving blowing structure outside the existing hydraulic pump, it is difficult to quickly dissipate heat from the outside of the hydraulic pump only through external wind operation, which in turn reduces the service life of the hydraulic pump
