Fluid on-line bubble-removing device

Abstract

A fluid on-line bubble-removing device aims to effectively remove bubbles from a fluid medium in a fluid transmission system, improve the system efficiency and prolong the working life, and comprisesa separator; the separator consists of a top cover (3), a separation cavity (5), an impeller (7) and a gas collecting pipe (11); the separation cavity (5) is arranged in a fuel tank (1); the top cover(3) is positioned at the top of the separation cavity (5); a bolt (2) is fixedly connected with the top cover (3), the separation cavity (5) and the fuel tank (1); a gas suction port of a vacuum pump(4) is positioned in the top cover (3); the gas collecting pipe (6) is communicated with the top cover (3); a bearing (12) is arranged at the bottom of the internal part of the separation cavity (5);the impeller (7) is arranged in the bearing (12); a motor (8) is connected with the impeller (7) through a shaft coupler (9); and the separation cavity (5) consists of an inner cavity (5-1), an outercavity (5-2) and an oil inlet (5-3).

Description

technical field [0001] The invention relates to the technical field of construction machinery, in particular to the technology of fluid on-line degassing. Background technique [0002] The fluid medium is an important part of the fluid transmission system, and its main function is to rely on its pressure to transfer energy and dissipate heat in the working system. It is unavoidable for the working system to mix air during work. The air is suspended in the medium by spherical bubbles with small diameters, and the existence of bubbles will cause problems such as cavitation and noise in the system, which seriously endangers the reliability and stability of the system. sex. [0003] The name in the prior art is "high-efficiency two-stage oil on-line debubbling device" (application number 201610778981.1). Although it is a purely mechanical structure without power and realizes the separation and filtration of air bubbles, it is not suitable for construction machinery. Under the ...

It is unavoidable for the working system to mix air during work. The air is suspended in the medium by spherical bubbles with small diameters, and the existence of air bubbles will cause problems such as cavitation and noise in the system, seriously endangering the reliability and stability of the system. sex

[0003] The name in the prior art is "high-efficiency two-stage oil on-line debubbling device" (application number 201610778981.1). Although it is a purely mechanical structure without power and realizes the separation and filtration of air bubbles, it is not suitable for construction machinery. Under the condition of large flow, the kinetic energy of the oil returned to the oil tank is small, and the oil viscosity is high, which cannot realize the rapid rotation and rapid discharge of the oil
