Abstract

The invention discloses a gas-liquid separation type constant-pressure oil tank and a control method thereof, comprising a fuel tank body and a pressure regulation system for actively adjusting oil pressure fluctuations inside the oil tank body, and the pressure regulation system includes a pressure regulator for regulating oil pressure Regulating system, a controller for controlling the pressure regulating system, and a supercharger connected to the fuel tank body and the pressure regulating system to transmit pressure regulation. Connected with the oil tank body, the invention can effectively solve the pressure fluctuation problem of the pressure oil tank under the working condition of motion, realize oil and gas separation at the same time, and effectively prevent oil oxidation.

Description

technical field [0001] The invention relates to a pressure oil tank, in particular to a gas-liquid separation type constant pressure pressure oil tank and a control method, belonging to the technical field of hydraulic transmission and control. Background technique [0002] Closed oil tanks are divided into isolated oil tanks and pressurized oil tanks, which are widely used in hydraulic systems such as walking machinery, underwater machinery, turning equipment, ships, and aircraft, which greatly improves the ability of equipment to adapt to complex environments and complex working conditions, and improves the hydraulic system. control performance. The pressure oil tank is also called the air-filled oil tank. The compressed gas with a pressure higher than the atmospheric pressure is filled in the oil tank, which improves the self-priming ability of the oil pump in the hydraulic system and effectively prevents the phenomenon of cavitation. According to whether the liquid is i...
