High-sealing-performance integrated hydraulic pump station

Abstract

The invention belongs to the field of hydraulic equipment, and particularly relates to a high-sealing-performance integrated hydraulic pump station. The high-sealing-performance integrated hydraulic pump station comprises an integrated box, a ventilation part, an oil tank, a motor, an oil pump and an integrated block; the ventilation part comprises a connecting pipe, a first fixing plate and a second fixing plate; the connecting pipe penetrates through the upper end of the integrated box, a plurality of sets of vent grooves are formed in the end, located outside the integrated box, of the connecting pipe in an annular array mode, and the two side ends of each vent groove penetrate through the inner wall and the outer wall of the connecting pipe correspondingly; the first fixing plate is a circular plate, the lower end face of the first fixing plate is fixedly connected with the upper end of the connecting pipe, and the central axes of the first fixing plate and the connecting pipe coincide; and a vent groove is formed in the upper end of the connecting pipe, the first fixing plate and the second fixing plate are combined to form a sealing cover arranged above the connecting pipe, the sealing cover is used for shielding the opening of the connecting pipe, and dust and other impurities are prevented from entering the connecting pipe to affect internal pressure relief of the integrated box.

Description

technical field [0001] The invention belongs to the field of hydraulic equipment, in particular to a high-tightness integrated hydraulic pump station. Background technique [0002] The hydraulic pump station is generally composed of a motor, an oil tank, an oil pump and an integrated block, and is suitable for various devices where the driving device is separated from the hydraulic pump station. [0003] Most of the existing hydraulic pumping stations are motors, oil pumps and integrated blocks installed on the fuel tank, and the whole device is exposed to the external environment, which is easily contaminated with dust and garbage, affecting use and maintenance. [0004] On the basis of the existing hydraulic pump station, a closed shell is installed. After the hydraulic pump station has been running for a long time, the temperature and air pressure inside the shell will have a large difference with the outside world, and it will be in this abnormal environment for a long t...
