It is impossible to completely clear and cure. Guangxi Komatsu excavator repair Nanning repair service center Komatsu digging machine repair company anti-wear, heat dissipation, viscosity temperature and chemical stability. But due to dust, sand, air, moisture and abrasive residues or intrusion into the hydraulic oil, will lead to the hydraulic system in the work of a vicious cycle, and ultimately can not work or paralyzed.

Contaminated hydraulic oil in the use of regular inspection to maintain maintenance

Simple from two aspects of the description of the reasons for the pollution of hydraulic oil and pollution of water pollution Guangxi Komatsu excavator repair Nanning repair service center Komatsu digging machine maintenance company a Xu production YZ12 full hydraulic vibratory roller, due to damage to the tank cover gasket , By the water pollution, before the winter did not replace the hydraulic oil, resulting in winter work finished, no warm library, rear wheel motor was frozen caused more than 20,000 yuan loss. A North from the production of 8 tons of car hanging, due to the hydraulic oil by the water pollution or a long time without the replacement of hydraulic oil, causing oil emulsion to reduce the lubrication performance, resulting in hoist motor cylinder and distribution plate, cylinder and plunger stick bite dead.

Second, the debris, dust, solid impurities pollution Guangxi Komatsu excavator repair Nanning repair service center Komatsu digging machine repair company a PC220-7 excavator work when the oil temperature reaches 80 ° C above the work of weakness, Turn off for a while and can work properly, and then the main pump overhaul. Overhaul after the failure phenomenon remains the same, the parking check to its detection, the main pump, the pilot pressure are normal, then the vehicle found that the vehicle when the pilot pressure less than 2.0Mpa (normal pressure 3.2Mpa). Guangxi Komatsu excavator repair Nanning repair service center Komatsu digging machine repair company so the self-pressure relief valve for demolition, found that the main valve from the pressure relief valve wear and pull marks.

Resulting in increased pressure of the hydraulic oil, the main valve issued pressure relief, replacement of the pressure relief valve, and the owner agreed to replace the hydraulic oil and filter, cleaning the fuel tank and pipeline, installed after the normal work. This failure to see the main reason is that the owner before the replacement of hydraulic oil when there is no cleaning tank, coupled with the oil change environment is bad, dust pollution is serious, filling the process caused by pollution. Pollution of the hydraulic system on the hydraulic system caused by the harm there are many, I do not do a detailed explanation here.

So that the use of hydraulic oil, Guangxi Komatsu excavator repair Nanning repair service center Komatsu digging machine repair company to do regular inspection, regular maintenance, regular replacement in the inspection and replacement. As little as possible with the air contact, the only way to ensure that the hydraulic oil is not contaminated or less polluted. Month, truck sales and sales of 18.94 million vehicles and truck non-complete vehicle production and sales; semi-trailer production and sales of 13,400 and 16,300, the chain fell in the first half of the truck truck production and sales of non-complete vehicle production and sales of 33.53 million and 357,800 , Down 11.07% and 7.14%; semi-trailer trailer production and sales
