How to maintain the cleaning and suction truck in winter?
Cleaning and suction truck
With the gradual cooling of the weather, people who buy cleaning and sucking vehicles should know about the maintenance of cleaning and sucking vehicles in winter. The four positions of cleaning and sucking vehicles should be well maintained, so as to ensure that the cleaning and sucking vehicles can work safely and efficiently in winter
1、tyre
In winter, vulcanized rubber becomes hard and brittle, its friction resistance will be reduced, and the standard pressure of tire can not be too high or too low. The temperature outside is too low, and the standard pressure of tire is too low, and the soft tire will accelerate the embrittlement of tire. In winter, buyers often remove the waste and dirt in the tread. If the tires are damaged, they can replace the new tires as much as possible, and the tyres with simple level of wear and different famous brands of patterns. They can keep pace with the parts of the tires on time, so as to ensure safety and reduce the wear of tires

2、Battery
Maintain electrolyte ratio and liquid level regularly. After the battery is fully charged, adjust the concentration of hydrochloric acid in the electrolyte. If the concentration of concentrated acid is too high, the service life of the battery will be reduced. The liquid level of electrolyte should be higher than 10-15 cm above the electrode. If the height is not up to the standard, the battery can be filled with liquid or pure water, and the electrolyte and drinking water need not be added immediately, which will lead to the damage of the battery
3、Automobile engine oil
Before the beginning of winter, replace with high-quality and high-efficiency automobile antifreeze and grease. The low viscosity automobile oil can reduce the wear level of mechanical equipment. Note: in the case of adding automotive antifreeze, the refrigeration system of diesel engine should be removed.
4、Suction system software

In winter, the air is cold. Pay attention to the clean water after each work to prevent the pipeline and pump shell from freezing and damaging.
