keep a small amount of cleaning water flowing along the shaft

　　 Protective packing of shaft seal the shaft seal pump shall regularly check the sealing water pressure and water volume, regularly adjust the packing gland, check the packing and regularly replace the packing. The shaft seal water pressure and water volume shall meet the above (shaft seal inspection) requirements.　　In addition to the method, materials shall be selected comprehensively according to the nature of corrosive medium, anti cavitation theory, corrosion mechanism of water pump and stress characteristics. In order to prolong the service life, which should be a comprehensive optimization design method.The Diwaniyah ,　　 Long term dehydration operation of submersible sewage pump: since the submersible sewage pump uses water as cooling water, the motor may overheat and burn due to long-term dehydration.　　 Then reinstall the equipment on the engine and install the rubber hose.Calceta,　　Turn on the power supply type fool operation; It has a wide range of applications. In many cases, it belongs to a portable workstation, which can be brought wherever it is needed, because it does not need too many auxiliary facilities.　　In fact the impeller clearance of submersible slurry pump is not adjustable for all types of pump, the clearance needs to be adjusted regularly to keep the clearance within the range suitable for normal operation.　　 repair and level the welding part of the submersible slurry pump with a file,The Diwaniyah WQ submersible sewage pump, clean the part to be bound with alcohol again and wipe it dry.

　　 The secondary pump shaft seal of the two-stage series pump is (packing seal), and the startup of the series pump also follows the above method. Only after the first stage pump is started, the submersible slurry pump can open the outlet valve of the last stage pump (the opening size is based on the motor current of the first stage pump as the rated power　　 design flow m/h　When using the submersible slurry pump, the equipment may be burned out. The main reason for this phenomenon is improper operation. How should we prevent the burning out?Let's see,　　When the slurry pump is working, the pump needs to be placed on land, the suction pipe in water, 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, the motor will fall into the water　　 One frequency converter with one slurry pump is adopted for installation. The specific transformation method is as follows: close the return valve, adopt the water level closed-loop control mode, install the liquid level sensor on the inner wall of the tank by the manufacturer of the slurry pump, and use the PID adjustment of the frequency converter. When　　The type selection planning of submersible slurry pump has a great impact on its service life and operation stability. A scientific and reasonable type selection plan will affect whether the slurry pump can achieve efficient operation. The operating power of the slurry pump is very high and the loss is small. Service life of flow passage parts of pump

　　It will burn out. If there is a heating problem in use, you can refer to the following reasons.assets,　　When this type of pump is used at ordinary times, the pump and motor operate in a coaxial whole. When it runs, the motor shaft will drive the impeller of the pump to rotate, and then at this time, the rotating force can be brought to the medium, so that　　 If the deep well pump is not used continuously after running in the well, it should be started up once a week and run for - minutes to prevent the electric pump from being started due to corrosion.　　 Next, the water seal, lock ring and other parts need to be installed.The Diwaniyah ,　　Normal operation. The submersible slurry pump can transport the slurry with corrosive or solid particles, coal slurry heavy medium transportation and dredging the river. When the equipment is pumping sand, some sand layers around the equipment will make the equipment covered by a large amount of sediment, and the current will slowly increase during use. Well, we should choose　　It will generate heat,The Diwaniyah Rubber lining submerged slurry pump, but when it is serious,The Diwaniyah Fire deep well pump, it will directly burn out the insulation; There may also be some faults in the ventilation system. At this time, it is necessary to check whether the fan of the submersible slurry pump is damaged or rotating　　Water pump After understanding the cause of insufficient liquid supply, we can solve the problem: First we need to check whether the liquid level of the circulating liquid storage tank needs to add media to it.
