The utility and durability of the utility model, so the polymer composite materials are generally used in production.　　 Moreover, the processes of these two pumps are also different, and the sewage pump can generally be adjusted. Submersible pumps are generally used in some special or other places.Catago,　　The microcomputer controller displays E: cause: the pressure gauge is disconnected (f= or the input signal is

　　 Cutting blades can be selected to cut some large block solid substances into pieces during use, so that blockage can be avoided during reuse.　　 The sealing oil chamber of WQ submersible sewage pump is equipped with a high-precision anti-interference water leakage detection sensor, and a thermal element is embedded in the stator winding to automatically protect the pump motor.　　Submersible slurry pump is a kind of pump that can adapt to various working conditions and can treat various sewage from environmental protection industry. Let&#;s take a look at the maintenance measures for the accessories of the submersible slurry pump.Workshop cost,　　Start the priming pump. Moreover, due to the structural limitations of the submersible slurry pump, the motor needs to be placed on the water surface for use during operation and then the pump needs to be placed in the water for use. Therefore, the submersible slurry pump must be　　Ensure that the service time will be extended when it is used. We all know that the submersible slurry pump needs to optimize its structure to meet the requirements of use because the medium it transports is relatively special. The structure has been optimized to　　We also need to limit the starting frequency and select appropriate thermal protection devices for use.

　　When the submersible slurry pump is used at ordinary times, which has a great impact on the impeller of the equipment itself. So how to detect whether there is cavitation when using the equipment at ordinary times?The cost is reasonable,　　When the slurry pump is working, the pump needs to be placed on land, the suction pipe in water,CatagoSubmersible sewage pump, and the pump needs to be started. Due to the structural limitations of the mud pump and submerged slurry pump, the motor needs to be placed on the water surface during operation, and the pump must be fixed when it is put into the water. Otherwise, the motor will fall into the water　　Stop the operation immediately under any of the following conditions: the current exceeds the rated value at the rated voltage; Under the rated head the flow rate is much lower than that under normal conditions; Insulation resistance is lower than . megohm; When the dynamic water level drops to the pump suction; When the electrical equipment and circuit are out of specification　　If the water leakage is serious, the broken pipe shall be dismantled and replaced. Lower the lift and press the nozzle of the water pump into the water for .m.Catago,　　As an emerging product, the submersible slurry pump has many advantages, the application of the submersible slurry pump is gradually becoming more and more widespread, and the market recognition is continuously improving, especially meeting the needs of deep-water sand pumping and dredging. At present, the depth can reach meters.　　What is the cause of pump overload.　　In fact, it can only be opened or closed, and the action time when opening and closing is relatively short.
