Abstract

The invention discloses an oil pollution monitoring and cleaning and filtering device of an embedded hydraulic power system, which comprises a main oil way A of the hydraulic system, a second electronic-magnetic or electronic-liquid steering valve which is arranged between the inlet and the outlet of the main oil way A of the hydraulic system. The device is characterized in that a branch oil way B is parallelly arranged on the inlet and the outlet of main oil way A of the hydraulic system, a branch oil way B is provided with a first electronic-magnetic or electric-liquid steering valve, a filter or a one-way valve and the filter is parallelly connected with a pressure gradient oil pollution monitoring and display device. The filtering device aims at not influencing the normal operation of the system when the attachment as the hydraulic equipment is embedded into the design of the hydraulic power system, monitoring results can better show the practical operation of oil.

Description

technical field [0001] The invention relates to a pollution monitoring and filtering and cleaning device for hydraulic equipment, in particular to an oil pollution monitoring and cleaning and filtering device for an embedded hydraulic power system. Background technique [0002] In modern hydraulic equipment, the pollution control and recycling of oil are very important. The failure rate of hydraulic equipment due to oil pollution accounts for more than 80% of the total failures. Many factories, enterprises or construction units have not carried out pollution monitoring on the oil used in hydraulic equipment, which makes the contaminated oil seriously affect the system. The service performance and life of each hydraulic component in the machine. Moreover, the oil used by factories and enterprises will be replaced with new hydraulic oil or oil after a certain period of time, and the used oil will be discarded, causing waste and environmental pollution, and increasing the prod...
