Submersible sewage pump used in the process of five "can not"

Submersible sewage pump in the course of the failure may be caused by the use of improper maintenance, such failures can be completely avoided, which requires you to use the process of diving axial flow pump to grasp the basic knowledge of the use of submersible sewage pump, as far as possible Reduce the human problem caused by the fault. Summed up the use of diving sewage pump in the five "no", I hope to help you.
    First, the submersible sewage pump can not be dehydrated operation. Submersible sewage pump in the anhydrous test run, the time shall not exceed 5 minutes. In the pumping process, if the water level is declining should pay attention to not let the pump body exposed to work.
    Second, the submersible sewage pump can not start immediately after shutdown. After the shutdown can not start immediately, you must wait for the tube after the return of water to start before starting. If the start diving axial pump can not be water, should immediately stop to identify the cause.
    Third, into the water or put forward the water can not pull the cable. Submersible sewage pump into the water or put forward the water, you must pull the rope, absolutely can not pull the cable. If you want to carry, disassemble or carry out maintenance should first cut off the power.
    Fourth, into the water when not lying. Diving sewage pump diving depth is generally 0.5 to 3.0 meters, when diving into the water should be vertical lifting, can not lie, but can not fall into the mud.
    Fifth, submersible sewage pump can not be used for irrigation and drainage of high water content. Submersible sewage pump should not be frequent start, not for drainage of sediment concentration Diving Axial pump higher water or mud water. Pumps can be used outside the bamboo mesh to prevent the water weeds plug the pump grid or catch the pump impeller.
