Abstract

The invention discloses a method for filtering the oil sucked by a heading machine oil pump. The method comprises the steps that a device is installed in the appropriate heading machine oil pump, an oil outlet and the arranged oil outlet pipe are connected with a connecting flange before use, fixing nuts are locked at the same time, an upper layer top cover is installed by using bolts and connecting nuts in cooperation, and the device can be in use after installation is completed. When the device is in use, eight oil inlets need to be completely immersed into oil to avoid the situation that working efficiency is reduced because no oil is sucked. Oil is sucked in through the oil inlets, and because a sealing ring is arranged between a main body shell and an inner cylinder separation layer,the airtightness between the space of the upper part and the space of the lower part of the device is guaranteed. Compared with the ordinary air filter element in the prior art, the tightness betweenthe inner top cover and the inner cylinder separation layer of the device is kept by using a fixing structure, it is avoided that the inner top cover inclines or shifts, the structure becomes more stable and practical, the fluid flow is increased, and the working efficiency of using the device is effectively improved.

Description

technical field [0001] The invention relates to the technical field of an air filter element, in particular to a filtering method for oil suction of an oil pump of an excavation machine. Background technique [0002] The oil suction filter is installed at the oil suction port of the oil pump to protect the oil pump and other hydraulic components, so as to avoid the inhalation of contamination impurities, effectively control the pollution of the hydraulic system, and adjust the cleanliness of the hydraulic system. [0003] Most of the oil pump filters of existing die-casting machines use one filter element. When a part of the filter element cannot be used, the entire filter element needs to be replaced, which will increase the cost of use. Therefore, it is necessary to improve the existing filter equipment to make it The filter element can be modularized to reduce the cost of use. In view of the above situation, technical innovation is carried out on the basis of the existing...
