Floor washing machine - how to do?
1. It may be that the purlins are worn badly and there are dirt on the squeegee. At this time, we should first clean the stains on the purlins. If the purlins are worn badly, we need to replace the purlins. After replacing the purlins, we can recover the previous suction effect. .
2. The clogging of the filter sponge or the unsuccessful placement of the sewage discharge cover may also result in insufficient suction of the floor scrubber. In this case, we have to check the filter system and the sealing performance of the floor scrubber and remove the dirt from the filter sponge. Drop it to make it clear and transparent.
Third, the seal ring is damaged, the connecting hose is damaged, and the connecting hose connector leaks or falls off. In this case we have to replace a new washer ring device. Replace the new connection hoses and the matching connection hose joints. The regular maintenance leads to a longer life and the washing machine can have a longer service life.
Four. The float can not be reset can also cause the scrubber suction is not strong enough. Then we must regularly remove the foreign objects on the float frame and the float ball to ensure that the buoyancy of the float ball can ensure the suction when scrubbing.
5. The O-pipe of the scrubber squeegee is damaged. The position of the squeegee is not adjusted to the optimal position, which may also result in insufficient suction. In this case we have to replace the new squeegee O-tube. Adjust the position of the squeegee so that the squeegee can reach the level of sewage that can clean the floor.
6. The recovery tank is damaged. Of course, the best thing is to replace the recovery tank.
