Automatic cleaning device of cylinder oil way

Abstract

The invention relates to an automatic cleaning device of a cylinder oil way, belonging to the technical field of vehicle product remanufacture. The automatic cleaning device of the cylinder oil way comprises a stream generating device, a backwater pipe, a closed water storage device, a control device and a connection device, wherein the stream generating device comprises a variable-frequency motor, a water pump, a pressure regulator, a pressure gauge and a brake valve, wherein the control device comprises a PLC (Programmable Logic Controller) and a plurality of two-position two-way electromagnetic valve for water, the connection device comprises a plurality of rapid joints, a plurality of water pipes, a planar oil way closing plate and a main bearing hole oil way closed plate. The invention improves the cleaning efficiency, reduces the labor intensity, decreases the cleaning cost, reduces the environmental pollution, ensures the cleaning effect and better satisfies the need for cleaning the oil way of a remanufactured cylinder.

Description

technical field [0001] The invention relates to a device in the technical field of automobile product remanufacturing, in particular to a cylinder oil channel automatic cleaning device. Background technique [0002] At present, more than 2 million cars need to be scrapped every year in our country, and a large number of waste cylinders are produced. Remanufacturing is to make the waste cylinders have a (Even exceeding) the quality and performance of the new cylinder, to achieve the purpose of turning waste into treasure. Cleaning is the most important and critical process in the cylinder remanufacturing process. The quality of cleaning directly affects the quality of cylinder remanufacturing. The cleaning of the oil passage is the top priority of cylinder cleaning. If the oil passage is not cleaned thoroughly, the impurities remaining in the oil passage will enter the friction pair with the flow of lubricating oil when the engine is working, causing early wear of the engine...

Problems solved by technology

The cleaning of the oil passage is the top priority of cylinder cleaning. If the oil passage is not cleaned thoroughly, the impurities remaining in the oil passage will enter the friction pair with the flow of lubricating oil when the engine is working, causing early wear of the engine. Seriously affect the performance and service life of remanufactured engines

[0003] The structure of the cylinder oil passage is complex, with many branches, and it is difficult to clean. There are two main traditional cleaning methods: one is to use a long and thin brush to dip diesel or engine oil into the oil passage for repeated scrubbing. This method is expensive to clean. , low efficiency, high labor intensity, it is difficult to achieve mass production, and cannot meet the requirements of cylinder remanufacturing; the other is to use high-pressure water jets to flush the cylinder oil passages, but because the high-pressure water jets enter the cylinder oil passages The speed and pressure attenuation is too fast, the water flow into each branch of the oil passage is very small, and the scouring effect on the inner wall of the oil passage is also sharply reduced. Therefore, this method cannot thoroughly clean the oil passage of the used cylinder body with serious pollution, and cannot meet the requirements of remanufacturing. Cylinder block oil passage cleaning requirements

[0004] After searching the prior art literature, it is found that there is no public literature report related to the automatic cleaning of the cylinder oil passage
