3. Reduce the influence from mechanical impurities
Mechanical impurity refers to the nonmetallic substance like outside dust, soil, and the metal filing, wear debris and other impurity that caused by machine self. Once the impurities enter into the machine, they will cause big hazard. Not only impede the relative movement, accelerate the parts abrasion, but also scratch the matching surface, destroy the lubrication oil film, enhance the spare parts temperature, and spoil the lubrication oil.
For the mining machinery that used in bad working environment and complex working site, we shoule use high quality and associated spare parts and lubrication oil and grease; Secondly, does good mechanical protection work to make sure the corresponding mechanism can work normally, and prevent various kinds of impurities enter into the machine.
4. Reduce the influence from temperature
Each spare part has its working temperature scope. Normally, the temperature of cooling water is 80-90℃, the temperature of hydraulic oil at hydraulic system is 30-60℃.If the temperature is lower or exceed this scope, it will accelerate the wear of spare parts, deteriorate the lubrication oil, change the materials performance and so on.
In the process of operating mining machinery, one is to prevent overload operation under low temperature, ensure the effective operation in preheat stage with low speed, and then start the machine until the machine reach the required temperature; The other is to prevent the machine working at high temperature. Should often check the thermometer, if found the problem stop for inspection and solve it immediately.
During daily working, should pay attention to the cooling system. For the water-cooled machinery, should check before work and add cooling water; for the air-cooled machinery, regularly clean the dust on the air cooling system to make sure there is no obstacle in the heat dissipation channel.
Right maintenance and repair is the precondition of prolonging the service life of mining machinery. Luoyang Dahua wishes each customer can take good care of the machine to prolong the service life and bring more benefits.
