Abstract

The invention relates to a hydraulic oil tank breather with a pre-compression type centrifugal separation mechanism. The hydraulic oil tank breather comprises an installation base, a shell body, a connecting base, a top cover and a cotton net filtering core. The installation base is provided with an exhaust valve assembly and an air inlet valve assembly. The exhaust valve assembly comprises an exhaust valve core, an exhaust spring and an exhaust screw plug. The air inlet valve assembly comprises an air inlet valve core, an air inlet spring and an air inlet screw plug. The hydraulic oil tank breather further comprises the centrifugal separation mechanism arranged between the shell body and the connecting base. According to the hydraulic oil tank breather with the pre-compression type centrifugal separation mechanism, the purposes are achieved, specifically, the exhaust valve assembly and the air inlet valve assembly are arranged on the installation base, a certain positive pressure in an oil tank can be maintained, and the normal air inlet effect can be ensured; oil particles in exhaust can be effectively adsorbed on the inner wall of a centrifugal separation barrel by arranging the centrifugal separation mechanism, and the concentration of the oil particles reaching the cotton net filtering core is reduced; and the cotton net filtering core is arranged in the top cover, the oil particles in the exhaust can be effectively absorbed, and thus the situation that the appearance of the hydraulic oil tank is affected due to the fact that the oil particles flow out from an air outlet hole of the breather and pollute the environment is avoided.

Description

technical field

[0001] The invention belongs to the technical field of oil tanks, and relates to a hydraulic oil tank respirator with a precompression centrifugal separation mechanism. Background technique

[0002] The hydraulic oil tank is an essential oil storage container for hydraulic equipment. When the piston rod of the hydraulic cylinder is stretched out, the hydraulic pump sends the hydraulic oil to the hydraulic cylinder, and when the piston rod of the hydraulic cylinder retracts, the hydraulic oil returns. The hydraulic oil tank, so the hydraulic oil tank needs to be provided with a breathing port to communicate with the outside, so that the air in the tank can flow in and out with the hydraulic oil in and out. After the equipment works for a long time, there are many hydraulic oil particles floating in the air in the hydraulic oil tank. When the hydraulic oil returns to the hydraulic oil tank, the hydraulic oil in the hydraulic oil tank increases, and the air is d...
