Protective packing of shaft seal the shaft seal pump shall regularly check the sealing water pressure and water volume, keep a small amount of cleaning water flowing along the shaft, regularly adjust the packing gland, the submersible slurry pump is developing rapidly with its unique advantages. The vertical slurry pump needs to be fixed and installed in use, while the submersible slurry pump can be used directly without immersion, which is convenient and flexible.Guaimaka,　　The following inspection shall be carried out: whether there are sundries between the impeller and the pump body due to too tight packing.　　Function of shaft seal of submersible slurry pump: the main of shaft seal is to prevent high-pressure liquid from leaking out of the pump and prevent air from entering the pump.Santo Joao da Madeira,　　 the submersible slag pump is often used to transport pulp containing solid particles, so the wear resistance of the pipeline should also be considered.　　 Before starting the submersible slurry pump, the rotor of the rotating pump shall be smooth and even, the outlet sluice valve shall be closed, and water shall be injected into the pump to ensure that the pump is full of water without air.　　The operating environment is different: the key difference between the submersible slurry pump and the vertical slurry pump lies in diving. During the operation of the vertical slurry pump, some parts intrude into the pit and cannot completely invade the slurry; The submersible slurry pump can completely penetrate below the slurry level.

　　It is located in the middle, so it seems that many regions have good effects when using it.　　 wellbore integrity　　The of descending axial force can be used for slurry transportation in power plants,GuaimakaSmall deep well pump, hydraulic and other professions; The mechanical seal is tight and reliable, and the leakage probability does not exceed drops /min, which is mostly used to transport flammable, explosive, toxic, strong corrosive and valuable liquids or materials with high temperature, high pressure and low temperature.Inspection standard, the cut impeller is usually used. The cut is　　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.　　 When the power supply voltage is too low,GuaimakaSewage pump diving,GuaimakaBaigang deep well pump, the pump will be overloaded, because the pump is also widely used in many rural watering. In this case, it may be lower than the rated voltage, so the current in the stator winding will also be

　　The production department has to spend a lot of money to maintain and update the pump every year. The pumps made of cast iron, bronze, rubber lining, stainless steel, titanium alloy and other materials used in China&#;s mining, chemical and water conservancy projects on the Yellow River are prone to wear, short service life and many faultsProfessional is king,　　Commodity.　　Sewage; QW series submersible sewage pumps are generally equipped with an elbow, and then connect the water pipe as required. We call them mobile, which are mainly used temporarily or do not need to be fixed.　　Fourth, model selection parameters: outlet diameter, flow, dust, impeller speed pumping rate, maximum particle and weight.Guaimaka　　Through the introduction, we learned that the submersible slurry pump can be used to transport slurry when it is used at ordinary times. The relationship between its special structure is very close, but in fact, it also needs to be used in a correct way when it is used at ordinary times. Only in this way can　　In fact, the impeller clearance of submersible slurry pump is not adjustable for all types of pump, but it is adjustable. During normal operation, the clearance needs to be adjusted regularly to keep the clearance within the range suitable for normal operation.　　 the water pipe shall be provided with a gate valve to regulate the pump working point. The valve shall be installed as close to the pump outlet as possible. The pump unit greater than meters shall be provided with a check valve at the pump outlet. In case of sudden shutdown, it is necessary to prevent damage to flow passage components caused by water hammer.
