The gas inadvertently entered in the equipment is discharged and good sealing performance is ensured.　　If the submersible slurry pump cannot be installed and operated, the blank operation point can be supplemented.Armenian,　　; When the electric pump has sudden noise or large vibration; When the protection switch frequency trips.　　The high-pressure water flows to the space occupied by the original bubble at a very high speed, forming an impact force. The metal surface of the pump was fatigued and damaged by these impacts. Cavitation is caused by air bubble rupture and material stamping due to the difference in air temperature and pressureBacchicapalanka,　　There are differences.　　When the submersible slurry pump is used at ordinary times, cavitation usually occurs, 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?　　Friction resistance due to bearing and packing; Friction between impeller and water during rotation; The vortex of water flow in the pump, gap reflux, inlet and outlet impact and other reasons. A part of the power must be consumed, so it is impossible for the water pump to completely change the power input by the power machine into effective power, in which the constant active power

　　 determination of model: for water pump or pump with physical and chemical medium similar to water, it is necessary to go to the relevant product catalog or sample, and make correction according to the performance table or performance curve of the model to see whether the normal working point falls in the priority working area of the pump.　　Automatic pump failure: cause: A. whether the frequency converter has abnormal symbols; b. Whether the actual pressure is higher than the set pressure.　　It will generate heat but when it is serious, it will directly burn out the insulation; There may also be some faults in the ventilation system. At this time,ArmenianISG single stage vertical pipeline pump, it is necessary to check whether the fan of the submersible slurry pump is damaged or rotatingDirect material, but its water output is not very large when it is used the head of the centrifugal pump itself is relatively high, so it is effective when it is used in many mountainous areas　　 add water with manual pump. Some pump owners have their own hand pumps. They can also buy or manufacture their own small hand pumps. The gate valve shall be installed at the water inlet. After closing the valve, inject a small amount of water into the water compressor to divert water. When the hand pump discharges water, it means that the pump is full　　Ordinary vertical motor can be used without waterproof, while the motor shaft and pump shaft of submersible slurry pump are coaxial, and the motor and pump can be immersed in liquid at the same time; The vertical slurry pump is an early product, and the submersible slurry pump is a newly developed product according to the market demand

　　 When stopping the operation of the submersible slurry pump, close the cock of the vacuum gauge and pressure gauge and the gate valve on the water outlet pipeline, and After that, cut off the power supply of the motor. If the temperature of the environment is low, open the square plug at the lower part of the pump body to remove the remaining water to avoid frost cracking. During operation, the maximum temperature of the bearing shall not exceed ℃, and the quantity of calcium base grease used for lubricating oil bearing shall be the same as that of the bearing bodyProfessional is king,　　 It may be that the motor power of the water pump is too large, the working current is too large, and the heat generation is too large, resulting in the high temperature of the vacuum pump.　　However, with the increase of pump operation time, which reduces the flow and head　　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 toArmenian it is equivalent to the downward movement of the pump H-Q curve,ArmenianSubmersible non clogging slurry pump,　　The motor is scrapped. Moreover, because the length of the long shaft is generally fixed, the installation and use of the pump is troublesome, and the application occasions are subject to many restrictions.　　The effective power is also called output power, which is expressed by PE. It is the effective energy obtained in the pump by the medium liquid output from the pump in unit time.　　It is not correct that it has no effect on us.
