Cylinder liner high pressure cleaner

Abstract

The invention discloses a high-pressure cleaning machine of a cylinder sleeve. The high-pressure cleaning machine comprises a rack, wherein the rack is horizontally provided with a conveying device which is provided with a cylinder-sleeve fixing position; the conveying device penetrates through five working positions on the rack in sequence from left to right: a feeding position, a rough-cleaning working position, a fine-cleaning working position, an oil-control working position, an antirust working position and a discharging position; the positions on the rack above the rough-cleaning working position, a fine-cleaning working position and the antirust working position are respectively provided with a rough-cleaning high-pressure spraying nozzle, a fine-cleaning high-pressure spraying nozzle and an antirust high-pressure spraying nozzle with downward openings; the upper parts of the rough-cleaning high-pressure spraying nozzle, the fine-cleaning high-pressure spraying nozzle and the antirust high-pressure spraying nozzle are respectively connected with a piston rod of a pneumatic device vertically arranged; the rough-cleaning high-pressure spraying nozzle is connected with a fine-cleaning oil pump; the antirust high-pressure spraying nozzle is connected with an antirust oil pump; the hydraulic pressure outputted by the rough-cleaning high-pressure spraying nozzle and the fine-cleaning high-pressure spraying nozzle is 2.0MPa-3.0MPa; and the hydraulic pressure outputted by the antirust high-pressure spraying nozzle is 1.0MPa-1.5MPa. The high-pressure cleaning machine disclosed by the invention has the advantages that the operation is simple, the labor intensity of workers is reduced and the working efficiency is improved.

Description

technical field [0001] The invention relates to a cylinder liner high-pressure cleaning machine. Background technique [0002] The cylinder liner is the heart of the engine. If the cleanliness and particle size of the cylinder liner are poor, the assembly accuracy will be affected during assembly. When the engine is working, the particles will scratch the inner hole surface of the cylinder liner and the outer surface of the piston ring, and in severe cases, cylinder scuffing will occur. The formation of blow-by gas and power reduction will seriously affect the life of the engine. Therefore, engine manufacturers have higher and higher requirements for the cleanliness of the cylinder liner. However, the cleaning device currently used in our factory requires 3 people to work together to complete it. The efficiency is very slow, and the labor intensity of the workers is high, and the cleaning effect is not ideal. OEMs often report that the cleanliness is too poor. Contents of ...

Problems solved by technology

[0002] The cylinder liner is the heart of the engine. If the cleanliness and particle size of the cylinder liner are poor, the assembly accuracy will be affected during assembly. When the engine is working, the particles will scratch the inner hole surface of the cylinder liner and the outer surface of the piston ring, and in severe cases, cylinder scuffing will occur. The formation of blow-by gas and power drop will seriously affect the life of the engine. Therefore, engine manufacturers have higher and higher requirements for the cleanliness of the cylinder liner.

However, the cleaning device currently used in our factory requires 3 people to work together to complete it. The efficiency is very slow, and the labor intensity of the workers is high, and the cleaning effect is not ideal. There are often feedbacks from OEMs that the cleanliness is too poor
