The invasion of cold air, the weather is getting colder, so we have to think about such a problem: how to ensure the normal operation of the sand making machine in low temperature environment?

In the winter when the temperature is low, in order to ensure the normal operation of the sand making machine, pay special attention to the correct maintenance, especi y the lubrication and maintenance work of the equipment. Therefore, when choosing a lubricant, it is also very :

1. We know that the volume of the sand making machine and the capacity of the fuel tank are not large, and the oil temperature is relatively high during work. Therefore, this requires the lubricating oil to have better thermal stability and oxidation resistance, and also has better anti-rust, anti-corrosion and anti-emulsification properties, so as to ensure the normal operation of the sand making machine.

2. In addition, many sand making machines work in the open air. Therefore, it is required that the viscosity of the lubricating oil changes little with temperature. It is necessary to avoid the viscosity of the oil becoming too low when the temperature is high, so that the lubricating film cannot be formed. To achieve the lubrication, it is necessary to avoid the viscosity is too high when the temperature is low, so that starting and running are difficult.

3. Also, due to the relatively dry climate in winter, in some places where fires are likely to occur, it is required to use a lubricant with good flame resistance (anti-flammable liquid) and not to use flammable mineral oil. The lubricant is required to be adaptable to the seal to prevent damage to the seal.
