Real-time monitoring and maintaining system for oil filter of large hydraulic excavator

Abstract

The invention provides a real-time monitoring and maintaining system for an oil filter of a large hydraulic excavator. The real-time monitoring and maintaining system comprises an oil filter II, wherein an oil flow detection device II is mounted at the oil inlet end or the oil outlet end of the oil filter; and the oil flow detection device II is connected with an oil filter real-time monitor. The real-time monitoring and maintaining system for the oil filter of the large hydraulic excavator can monitor the service life condition of a filter element in real time and can perform visual display; according to the preferable scheme, the real-time monitoring and maintaining system comprises a main system and an auxiliary system, so that even if the filter element of the main system cannot be maintained in time due to various reasons, the auxiliary system still can replace the main system to work, and therefore, the problem that an engine is severely damaged as oil supply amount is severely affected as the filter element is blocked is prevented. A parallel system design of the real-time monitoring and maintaining system can realize non-stop maintenance.

Description

technical field [0001] The invention relates to the technical field of life detection of an excavator oil filter, in particular to a real-time monitoring and maintenance system for a large-scale hydraulic excavator oil filter. Background technique [0002] Under normal circumstances, all parts in the engine are lubricated by oil to achieve normal work. The function of the oil filter is to filter most of the impurities in the oil, keep the oil clean and prolong its normal service life. The role of the oil filter is very important. The filter element is an important part of the oil filter. However, the traditional oil filter is not equipped with a detection device for the blockage of the filter element. Once the filter element is blocked, it will seriously affect the oil supply. Serious damage to the engine. Now the life of the oil filter element is generally maintained regularly, and replaced when the maintenance mileage or time is reached. The traditional filter element ma...

AI Technical Summary

Problems solved by technology

The traditional filter element maintenance method cannot test the filter element resistance in real time. Generally, the filter element is replaced in advance, and the actual filter element still has a surplus, resulting in waste

In addition, there will be situations where the filter element has reached the replacement standard, but it has not been replaced in time

Existing filter elements cannot detect the resistance of the filter element, and it is impossible to determine whether the filter element meets the replacement standard
