Super-high flow return-oil defoamer

Abstract

The invention relates to a super-high flow return-oil defoamer, in particular relates to a heavy mining dumper, and belongs to the hydraulic field. The defoamer is characterized in that a base is provided with a connecting hole and is fixedly connected with one end of a shell; the other end of the shell is fixedly connected with a bottom plate, and the bottom plate is provided with a hole; and a cross-shaped partition plate is arranged in the shell and is provided with an oil hole. The super-high flow return-oil defoamer is of an integral cylindrical structure, wherein the base is connected with an oil return pipe in an oil tank through an internal 6''NPT (national pipe thread) so as to play a role in connection and ensure the airtightness of the joint; the shell, the bottom plate and the cross-shaped partition plate are provided with oil passing holes, and the flow rate of the hydraulic oil is reduced so as to prevent air bubbles from occurring when hydraulic oil passes through the oil passing holes; and a baffle is arranged at the bottom side of the hydraulic oil tank so as to prevent the high-flow hydraulic oil from washing away the dirt precipitated on the bottom of the oil tank.

Description

technical field [0001] The invention relates to a super-large flow oil return defoamer, in particular to a heavy-duty mining dump truck, which belongs to the field of hydraulic pressure. Background technique [0002] The oil return defoamer plays a very important role in the hydraulic system. It is mainly used in the non-return oil filter hydraulic system. It can prevent the large flow hydraulic oil returning to the oil tank from generating air bubbles. It is especially widely used in mobile machinery. Due to the large tonnage of heavy-duty rigid mining dump trucks, the displacement of hydraulic pumps is very large, and most of them use high-pressure filtration (that is, high-pressure filters are designed at the outlet of the pump), so it is very necessary to install an oil return defoamer on the oil return pipeline ; But at present, manufacturers rarely produce oil return defoamers with very large flow, and the connection method is complicated. The material is mostly stainl...

AI Technical Summary

Problems solved by technology

Due to the large tonnage of heavy-duty rigid mining dump trucks, the displacement of hydraulic pumps is very large, and most of them use high-pressure filtration (that is, high-pressure filters are designed at the outlet of the pump), so it is very necessary to install an oil return defoamer on the oil return pipeline ; But at present, manufacturers rarely produce oil return defoamers with very large flow, and the connection method is complicated. The material is mostly stainless steel mesh, which has large oil return resistance and poor defoaming effect; The dirt deposited at the bottom of the fuel tank will cause oil pollution; therefore, it is necessary to design a return oil defoamer suitable for heavy-duty rigid mining dump trucks
