Why do excavators use hydraulic hammers and the hydraulic oil turns black?

2019-08-09

The reason of gear oil blackening of excavator:


First, there should be metal material residue;


Second, the office environment is not very good, external air pollutants into the gear oil.


The origin of iron pin and how to prevent it are discussed below


1. There will be wear debris caused by high-speed operation of the pump. You must fully consider the damage of all components related to pump rotation, such as rolling bearing, capacity chamber, etc;


2. The wear debris caused by the back and forth operation of the hydraulic cylinder and the valve core of the hydraulic solenoid valve is not easy to occur in this short period of time;


3. Because it is a new equipment, there are many iron pins in the running in period of machinery and equipment. I wonder if you will clear all the gear oil in the oil tank when you change the oil. After using the breathing system of the new oil circulation system, the hydraulic hammer manufacturer will clean the oil tank with pure cotton cloth and add new oil. If not, there will be a lot of iron pins left in the oil tank It will also cause the new oil to become black due to environmental pollution;


Look at the external environmental hazards


You should check whether your hydraulic transmission system is closed and whether the suction hole is intact; check the exposed components of the hydraulic press of the machine equipment to see whether the sealing is intact, such as the dust ring of the hydraulic cylinder, etc;


1. The gear oil is not changed neatly when changing;


2. The skeleton seal is brittle;


3. The filter element is blocked due to poor working environment of excavator;


4. There are many bubbles in the inlet gas of hydraulic oil pump;


5. The hydraulic oil tank is interconnected with the gas. The dust and residue in the gas will enter the automobile oil tank after a long time of application, and the oil will undoubtedly be dirty;


6. Diesel particle size test is in line with the cleanliness requirements. It can remove the smoke and dust pollution. There is no doubt that it is caused by the high temperature of gear oil! We can use high-quality gear oil, check the oil return filter element, heat pipe heat dissipation fuel pipe, and the most important thing is the heat pipe radiator of gear oil! Usually, maintenance should be carried out according to the regulations!
