There are 2 sets of waterway systems on the road sweeper truck, a set of low-pressure sprinkler spray dust reduction function, and a set of high-pressure flushing functions. When the waterway system passes through the high-pressure pump and the low-pressure electromagnetic pump, in order to avoid impurities in the waterway from damaging these two waterway systems. Set up a water filter system. The function of this water filter is very important. It can effectively avoid the damage and non-operation of the water pump caused by the blockage of the water pump, so as to better wash the road surface, clean the road, spray dust and so on. Let's take a look at the necessity of cleaning the water filter of a road sweeper and how to clean and maintain it.

Sweeper truck drivers must observe whether the filter element is clogged with impurities through the time-permeable cover of the water filter every day and clean it up in time (the place with more scale must be cleaned up in time after every tank of water is used up). If the water filter is not cleaned for a long time until the waterway system is seriously blocked, the vehicle dust reduction system will not spray water, and the water pump will be burnt due to dry running without water.

The cleaning and maintenance methods for the water filter of the road sweeper trucks are as follows:

Find the location of the water filter of the road sweeper truck, usually installed at the bottom of the water tank; if there is residual water in the water tank, please close the main water valve and unscrew the water filter cover counterclockwise. If necessary, use special tools to remove it; after removing the filter cover, Unscrew the water filter element counterclockwise; rinse the filter cover and drain valve with clean water until it is unobstructed, and rinse the water filter element with clean water until there are obvious impurities; install and tighten it in the original position after cleaning. Basically, the color of the filter will become yellowish when the filter cup is clogged, so it must be cleaned in time. If the water quality is not good, it is best to clean it every 3-7 days to avoid clogging.

The road sweeper truck water filter is an indispensable device on the pipeline of the conveying medium. It is usually installed on the pressure reducing valve, the pressure relief valve, and the fixed water level valve. The filter consists of a cylinder, a stainless steel filter screen, a sewage part, a transmission device and an electrical control part. After the water to be treated passes through the filter cartridge of the filter screen, its impurities are blocked. When cleaning is required, only the detachable filter cartridge can be taken out and reinstalled after treatment. Therefore, the use and maintenance are extremely convenient.

The filter element of the water filter can be replaced, and the service life is generally 3-6 months.
