Service life detection device and detection method for filter screen of oil pump

Abstract

The invention discloses a service life detection device and detection method for a filter screen of an oil pump. The filter screen is arranged at an oil inlet of the oil pump. The detection device ischaracterized by comprising an ECU control unit, a flow meter and an alarm unit, the flow meter is arranged on an oil inlet way of the oil pump and detects oil inlet flow signals of the oil pump, an output end of the flow meter is connected with a flow signal input end of the ECU control unit, and the ECU control unit is connected with the alarm unit. When the flow signals acquired by the flow meter are larger than a flow threshold set in the ECU control unit, the ECU control unit controls the alarm unit to alarm. Automatic detection of utilization conditions of the filter screen is realized,optimal replacement or cleaning time of the filter screen can be judged, reasonability in use of the filter screen is improved, reasonable suggestions can be provided for a user to replace the filterscreen, and serious pollution of the filter screen can be avoided.

Description

technical field [0001] The invention relates to a detection device and method, in particular to a life detection device and method of an oil pump filter net. Background technique [0002] Most of the existing oil pump filter screens on the market have a filtration accuracy of 15-30 microns. During use, the filter screen filters impurities in the fuel. When used to a certain extent, a new filter screen needs to be replaced. Due to the different countries or regions that produce fuel pump filters, the oil products used in vehicles vary greatly, resulting in different service life of filters, which brings great troubles to customers and manufacturers, and cannot determine the life cycle and replacement time of fuel pump filters. If the replacement is in advance, the after-sales cost will increase. If the replacement is delayed, the filter will be damaged and the filtration efficiency will decrease. Different types of damage such as unstable oil pressure. If there is a problem...

Problems solved by technology

Due to the different countries or regions that produce fuel pump filters, the oil products used in vehicles vary greatly, resulting in different service life of filters, which brings great troubles to customers and manufacturers, and cannot determine the life cycle and replacement time of fuel pump filters.

If the replacement is in advance, the after-sales cost will increase. If the replacement is delayed, the filter will be damaged and the filtration efficiency will decrease. Different types of damage such as unstable oil pressure

If there is a problem with the oil pump, it will also cause the fuel injector to be blocked and the performance of the whole vehicle to be abnormal
