Problems solved by technology
When the air in the hydraulic oil tank enters and leaves the respirator with this structure, the hydraulic oil particles contained in the air adhere to the filter cotton. When the hydraulic oil adhered to the filter cotton reaches saturation, the hydraulic oil on the filter cotton is exhaled. Under the action of airflow and gravity, it flows out through the air outlet of the respirator to pollute the environment and affect the appearance of the hydraulic oil tank

Embodiment Construction
[0029] Hereinafter, the preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings.
[0030] Such as Figure 1-4 As shown, a hydraulic oil tank breather with a pre-compression centrifugal separation mechanism includes a mounting seat 1, a housing 2, a connecting seat 3 and a top cover 4. The housing 2 is arranged on the mounting seat 1, and one end of the connecting seat 3 is connected to The housing 2 is connected and provided with a first gasket 13, the other end is connected with the top cover 4, a cotton filter element 5 is provided between the connecting seat 3 and the top cover 4, and a second gasket 14 is provided at both ends, on the mounting seat 1. An exhaust valve assembly 6 and an intake valve assembly 7 are provided. The exhaust valve assembly 6 includes an exhaust valve core 61, an exhaust spring 62 and an exhaust plug 63. The intake valve assembly 7 includes an intake valve core 71 and an intake valve core...

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 pre-compression type 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 extends, 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 Hydraulic oil tank, therefore, the hydraulic oil tank needs to be provided with a breathing port to communicate with the outside, so that the air in the tank enters and exits as the hydraulic oil enters and exits. When the equipment is working 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 di...
