Description

Integrated gear pump
Technical Field
The invention relates to a hydraulic gear pump. Belongs to the technical field of hydraulic transmission.
Background
In a conventional hydraulic system, a gear pump is separately installed on an engine, a hydraulic oil tank, a filter, the gear pump and a hydraulic valve are connected through a system pipeline, a joint and an integrated valve block, and all hydraulic elements are distributed at different positions of a mechanism. According to the applicant, the pressure loss of the conventional hydraulic system pipeline and the sealing leakage of the interface are problems which are difficult to avoid, and meanwhile, the hydraulic system with the scattered layout is inconvenient to install and maintain and high in manufacturing cost and management cost. Thus reducing the pressure loss of the hydraulic system pipeline; the manufacturing cost is reduced; reducing leakage from the interface; miniaturization and portability; the installation and maintenance are convenient; the reduction of the installation space is the innovative research and development direction of the patent.
Disclosure of Invention
The technical problem to be solved by the invention is as follows: the hydraulic system aims at the problems of pressure loss of the conventional hydraulic system pipeline and sealing leakage of the interface mentioned in the background art and the defects of inconvenient installation and maintenance, high manufacturing cost and high management cost of the dispersed layout.
In order to solve the technical problems, the hydraulic component is organically integrated into a compact system component according to the performance level of the existing hydraulic component and the manufacturing process level of the hydraulic system, so that the hydraulic system is more compact, the manufacturing cost and the management cost of the hydraulic system are reduced, and the total efficiency of the hydraulic system is improved on the premise of meeting the functional requirements.
The hydraulic oil pump comprises a hydraulic gear pump, an oil duct arranged in a gear pump shell, an oil tank sealing structure on the gear pump shell, a cartridge valve jack on the gear pump shell, a hydraulic oil tank, a filter, a cartridge valve, a sealing piece, a fastening piece and the like. A built-in oil passage, an oil tank sealing structure and a plug-in valve jack are designed on a gear pump shell.
The hydraulic oil tank is fixed on the shell of the gear pump by a sealing piece and a fastening piece, the gear pump is connected with an oil path of the hydraulic oil tank by an oil passage arranged in the shell of the gear pump, and the filter is arranged in the hydraulic oil tank.
The threaded cartridge valve is inserted into the valve mounting jack, and the threaded cartridge valve is connected with an oil path of the gear pump through an oil path designed in the gear pump shell.
By adopting the technology, the dispersed hydraulic elements are integrated into an organic system component whole, so that the structure of the hydraulic system is more compact, the total efficiency and the sealing performance of the hydraulic system are improved, and the manufacturing cost and the management cost of the hydraulic system are reduced.
