Explore the reason why the brush plate of the floor scrubber can't be raised and lowered
Nowadays, there are two types of floor washing machines in the market. One is the automatic lifting brush tray rack suction grill, the other is the manual lifting rod lifting brush tray and suction grill. The two types of floor washing machines with different configurations work in the same principle, but the operation is manual and automatic. Generally speaking, the failure rate of manual lifting is low and the maintenance is simple, while the automatic and manual lifting are easy The dynamic lifting is a little more complicated, and the maintenance cost is much higher. What's the fault of the brush plate of the driving washing machine failing to lift?
The main reasons why the brush plate of the driving washing machine can not be lifted and lowered are as follows:
First, the automatic button of the brush disc of the driving type floor washer is damaged. This kind of situation is very rare. Basically, this kind of situation occurs only after the switch is filled with water. If the brush disc fails to rise and fall automatically, we can only check the start switch.
Second, the chain connecting the brush disc bracket and the lifting motor is damaged. In this case, the fixing plate of the connecting chain between the brush disc bracket and the lifting motor is damaged. Only replace the new fixing plate.
Third, the brush plate lifting motor is damaged. This kind of problem is less likely to occur. If there is such a situation, we only need to check the circuit of brush disc lifting motor, carbon brush and other aspects.
