Ways To Improve Lubrication System Cleanness II

In this last part, we introduced three ways to improve the mining machine lubrication system cleanness. In this article, we focus on the other three ways.

Irregularly Clean& Wash The Lubrication System

When there is water or some other liquids enter the lubrication system of mining machine or there is metallic material in the lubrication system, or the mining machine hasn’t been used for very long time, we all should change the lubricating oil to ensure the cleanness of the lubrication system. If the lubricating oil pipe oxidizes serious or there is oil sludge piled in the pipe, we should adopt acid pickling to clean it. But generally, we can only flush the pipe.

The flushing steps are: when the oil temperature is about 30 ℃~ 40 ℃, we can discharge the original lubricating oil as much as possible. If necessary, we can adopt compressed air to help discharge the lubricating oil. And then, adopt light oil, kerosene or spindle oil to clean the lubricating oil tank. After discharging the original oil, we can adopt turbine oil to wash the tank.

Generally, we install a filter with 20-30μm in the scavenger circuit and wash the lubricating oil tank for about 1 to 2 hours. The temperature of turbine oil should be kept at 60-70℃. In order to improve the washing efficiency, we can knock on the pipe slightly. After washing the tank, we discharge the turbine oil and then clean the oil tank by sponge material. At last, add new lubricating oil into the tank.

Strengthen Assemble System And Improve Assemble Quality

Every time we maintain the crushing& grinding equipment, the lubricating oil pipe needs to be dismantle and assembled again. So we should improve the responsibility of operators. After dismantling the oil pipe, operators should block up the two sides. And in the process and assemble process of spare parts, operators should remove and clean the burr and welding slag timely.

Improve The Sealing Of Lubrication System

Another way to improve the cleanness of lubrication system of mining machine is to improve the sealing of the lubrication system. We can adopt methods to avoid the entering of impurities, such as adding cover to the oil tank, adding air sealing device in jaw crusher etc.
