Winter is coming, how to protect the crusher from the cold

In recent years, my country's mining machinery industry has continued to grow and develop. Crusher plays an extremely important role in the fields of mining, machinery, construction, building materials, and mineral processing. The number of domestic crusher manufacturers has also increased, and product performance has been continuously improved. .

The temperature usually has a certain impact on the performance of the crusher. The winter of 2017 is coming, and the temperature will be getting lower and lower. How should the mining industry protect the crusher from the cold?

Hongxing Machinery believes that if jaw crushers, cone crushers, impact crushers and other crushing equipment work in a relatively low temperature environment, not only will their service life be reduced, but the water or oil in the crusher will also be damaged. Therefore, it is very necessary to conduct a thorough inspection and maintenance of the crusher before winter. Maintenance of the crusher in winter needs to start from the following aspects:

1. Crusher cleaning

Regular cleaning of the chassis, working devices and other parts of the crusher can effectively remove the dirt on the surface of the crusher. At the same time, during the cleaning process, it can also be found whether each part is worn, laying the foundation for further maintenance. When cleaning, it should be noted that it is forbidden to use high-pressure and high-temperature water guns to clean electrical appliances and other parts to avoid damage.

2. Oil selection and replacement

1. Selection of fuel oil

In a low-temperature environment, diesel oil is more prone to waxing, its viscosity increases, and its fluidity becomes worse, resulting in incomplete combustion and reducing the power of the diesel engine. In order to reduce the fuel consumption of diesel oil, it is necessary to use diesel oil with a relatively low freezing point. Moreover, it is necessary to clean the fuel system, thoroughly clean the filter screen, and check the condition of the fuel pump at the same time to eliminate hidden dangers.

2. Replacement of diesel engine oil

Diesel engines should use low-temperature engine oil with relatively low viscosity. The use of high-performance engine oil can not only make the engine oil not easy to oxidize at high temperature, but also avoid leaving deposits on the diesel engine parts, thereby prolonging the life of the diesel engine.

3. Replace lubricating oil and grease

When winter is approaching, it is best to replace the gear oil in the transmission and differential with the gear oil that can be used in winter.

3. Maintenance of spare parts

1. When maintaining the cooling system of the diesel engine, it is necessary to check the working status of the thermostat. Once mud and sand deposits are found in the water tank, they must be removed immediately.

2. Check whether the motor wiring of the battery is normal. It is necessary to charge the battery frequently in winter and maintain the preheating device.

3. The maintenance of the brake system needs to check whether the brake fluid is sufficient, whether the oil-water separator and the anti-fouling switch are normal. For abnormal phenomena such as braking weakening and deviation, it is necessary to adjust in time.
