Hydraulic system of hydraulic waste paper baler
Author : admin Time : 2020-11-10 AllPageView : 211
Hydraulic system of hydraulic waste paper baler The hydraulic waste paper baler is specially used for the recovery and compression of waste paper, waste cardboard, carton factory scraps, waste books, waste magazines, plastic film, straw and other loose materials.
During the maintenance of a NKW60Q hydraulic waste paper baler, Nick Machinery’s after-sales service found that the cylinder liner of the diesel engine, especially its thrust side, had honeycomb-shaped holes.

When the hydraulic valve was in the distribution room,it was found that the mating surface became black with scratches and small pits,which is a phenomenon of cavitation.

Cavitation occurs because when the oil pressure is lower than the oil-gas separation pressure,the gas dissolved in the oil will form a ‘cavity’ in the oil.When the pressure reaches a certain value again,These bubbles burst immediately under the action of pressure,resulting in high temperature and high pressure.When they act on the surface of the part,the part will be damaged.Due to the high precision of the hydraulic components of the hydraulic waste paper baler and the small fit gap between the relative moving parts,the mating surface will become black and even small pits will appear after the cavitation occurs,which will cause the Min core to jam and the pressure will be out of adjustment.
When the cavitation of the cylinder liner is heavier,the damaged area will appear deep and irregularly shaped dents,as if the surface of the cylinder liner has been corroded by strong acid;when the cavitation is more serious,four points will penetrate the cylinder liner wall.
The cooling liquid in the machine body enters the cylinder,causing serious engine accidents.When cavitation is combined with other types of corrosion,the damage rate will increase exponentially or even dozens of times.
