Problems solved by technology

[0002] In the field of hydraulic transmission and control technology, the oil suction of the hydraulic pump is mainly realized by the vacuum degree generated by its oil suction port. In many cases, the hydraulic pump will generate oil suction noise, and when the speed of the hydraulic pump increases, there will be insufficient oil suction. And accompanied by greater noise, which limits the further development of the potential of the hydraulic pump
In order to solve this problem, the main pump is often forced to supply oil by a low-pressure pump, or a high-level oil tank is used, and sometimes a closed system with more complex functional components is used, which makes the structure of the system more complicated.
After searching, no relevant patents and public documents for low-pressure pressurization of fuel tank liquids were found

Embodiment Construction

[0012] The supercharging device consists of a supercharging cylinder 1, a supercharging piston 2, a piston seal ring 3, a hollow piston rod 4, a pressure setting spring 5, a pressure regulating cover 6, a leak detection scale 7, and three combinations of oil injection, pressure measurement and temperature measurement. Pass 8, pressure gauge 9, one-way valve 10, temperature gauge 11 composition.

[0013] During implementation, the supercharging device is installed on the liquid-filled oil tank, and the supercharging piston 2 isolates the oil from the atmosphere. After the oil tank and system with the supercharging device are installed, refuel the liquid-filled oil tank and the hydraulic system At this time, the maximum pressure of the oil filter truck is slightly higher than the required filling pressure of the fuel tank (it is required that the minimum oil discharge pressure of the hydraulic system and the pressure resistance of the fuel tank should be higher than the required ...

Abstract

The invention relates to hydraulic reservoir liquid low-pressure charging device. It belongs to hydraulic transmission and control technical field. The upper of the super charging cylinder is connected to oil case. The super charging piston is set at the bottom of the cylinder. And its cylinder face is set sealed groove. And piston sealed ring is set in it. Hollow piston bar is connected to the center hole of the super charging piston. Pressure setting spring is set on the hollow piston bar. And its lower end is touched with the piston surface. Its upper end is touched with the pressure regulating. The invention can improve oil supply for hydraulic pump, and has bubbling volume monitoring function.

Description

technical field [0001] The invention relates to the technical field of hydraulic transmission and control, in particular to a low-pressure supercharging device for liquid in a hydraulic system oil tank. Background technique [0002] In the field of hydraulic transmission and control technology, the oil suction of the hydraulic pump is mainly realized by the vacuum degree generated by its oil suction port. In many cases, the hydraulic pump will generate oil suction noise, and when the speed of the hydraulic pump increases, there will be insufficient oil suction. Accompanied by greater noise, the further exertion of the potential of the hydraulic pump is limited. In order to solve this problem, the main pump is often forced to supply oil by a low-pressure pump, or a high-level oil tank is used, and sometimes a closed system with more complex functional components is used, which makes the structure of the system more complicated. After searching, no relevant patents and public...
