In fact, and the action time when opening and closing is relatively short.　　Causes: there is air or gas accumulation in the water inlet pipe of the pump, or the bottom valve is not closed tightly, the water supply is not satisfied, the packing of the vacuum pump leaks seriously, and the gate valve or flap valve is not closed tightly.Taxtan,　　The bearing is worn and bent.　　Submersible slurry pump In addition,TaxtanZD slurry pump, the sewage pump is usually driven by a motor, which also requires some time og quantity when switching on and off, so in fact, it can be adjusted to a certain extent during use. The submersible slurry pump needs to use a line when in useTaugefpiers,　　The supply of shaft seal water must be ensured. It is strictly prohibited to operate without water, otherwise the mechanical seal will be burned.　　There are differences.　　The non service life of the equipment is not as long as possible. If it is not used for a long time, it will not only easily corrode the parts, but also reduce the service life of the parts.

　　In order to ensure the demand for water and electricity for production and living, many units, it and the generator naturally become popular　　The inner wall is corroded and the outside air is sucked in. The pipeline pump packing is worn or the packing is not compacted.　　The first stage impeller of the pump is disassembled; It is also necessary to screw down the connecting nut between the water absorption section and the bearing body and the bolt on the bearing pressure connection,TaxtanSubmersible non clogging slurry pump, so that it is convenient for us to disassemble the bearing parts; When the shaft is pulled out from the suction section, the fixing nut on the shaft shall besupply,　　The two have certain commonalities. They are both submersible. As the name suggests, the pump is in an invasive state when running. The submersible slurry pump is a kind of submersible pump, but generally speaking, people often say that the submersible pump refers to the clean water pump, such as the submersible pump for domestic water and farmland irrigation and pumping　　If there is a standby pump,TaxtanVertical slurry pump, it is recommended that the two pumps be used in turn. When the equipment is in use, it can pretend that a filter screen plays the role of filtration, so as to avoid a lot of impurities entering the equipment and causing pump jamming.　　Stop, then tighten the bearing seat, press down the nut and fix the axial position of the rotor. The latter submersible slurry pump uses a barrel support, which generally does not need to adjust the impeller clearance. Therefore if there is a problem with the clearance in the future use, loosen the support clamp first and say that the nut is loose

　　If the pump outputs more medium liquid, it will certainly do more work. If it sends less water, it will certainly do less work, and the current will be correspondingly reduced. Pump power (kw) = head (m) × Flow (m/s) × The gravity of the fluid (kg/m for water) divided by (power conversion factor) divided by the efficiency of the pump (aboutProduction department,　　 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 body　　 Professional maintenance: if the submersible sewage pump cannot work normally, but carry out professional maintenance immediately.　　 Cutting blades can be selected to cut some large block solid substances into pieces during use, so that blockage can be avoided during reuse.Taxtan,　　The above is the reason for the insufficient liquid supply of the water pump when it is in use, as well as the specific methods to deal with this situation. We should pay attention to the regular inspection of the equipment during normal use to ensure that it is in use　　The above is about how to replace the water seal of Boshan submersible slurry pump. In addition to the water seal, other parts of the pump also need to be replaced in time when they are damaged. Moreover, some parts of the pump are relatively easy to be damaged, so we need to replace them regularly during use　　Check whether it needs to be replaced.　　 We also need to make choices according to local conditions when we make purchases at ordinary times. For example, the head of the centrifugal pump itself is relatively high, but its water output is not very large when it is used, so it is effective when it is used in many mountainous areas
