People usually carry out all the normal maintenance of the sand making machine in addition to the ultra-low temperature in winter, in order to ensure that all the normal work of the sand making machine, especially in the attention to proper maintenance, it is very much the polishing work of the machine and equipment.
It is understood that the volume of the sand making machine and the volume of the car fuel tank are not large, and the water temperature is relatively high when working. Therefore, this requires that the grease has good heat resistance and oxidation resistance, and it must also have good anti-rust treatment, corrosion resistance and anti-emulsification characteristics, so as to ensure that all the normal work of the sand making machine.
In addition, many sand making machines are all outdoor work, so the change of grease viscosity with temperature is required to be small, not only to prevent the temperature is high, the viscosity of the product oil is getting too low, so that it can not produce a wetting film, and it cannot achieve the wetting effect, but also to prevent the viscosity is too high when the temperature is low, so that it is difficult to start and run.
Also, because the winter weather is more dry and volatile, in some areas that are very easy to catch fire, it is stipulated that a strong flammable lubricant (anti-burning liquid) should be applied, and flammable mineral oil should not be applied. It is stipulated that the lubrication fluid has a better adaptability to the hydraulic seal to prevent the hydraulic seal from being damaged.
