The submersible slurry pump shall be shut down for inspection in time in case of machine problems during operation, and regular maintenance shall be done. The equipment will not be used after burning out, which will cause certain economic losses to us.　　There is no need to equip auxiliary mixing or spraying equipment and the operation is simpler. The equipment is directly submerged for operation, without noise and vibration, and the site is cleaner.Payback,　　Work to prevent the electric pump from overheating and damage. The technical guidelines for laboratory construction in medical institutions (Trial Implementation) directly proposed that stainless steel should be used. Compared with the technical code for construction of biosafety laboratories (gb-, copper pipes and non-toxic plastic pipes are no longer proposed.　　The above is a brief introduction to the effect and form of shaft seal of submersible slurry pump. Users can choose the appropriate shaft seal type according to their actual needs.Jitra,　　The above four methods can be used to detect whether the submersible slurry pump has cavitation, because if the equipment is in use, it will have a great impact on the operating efficiency. Even if the cavitation time is long, it will also have a certain impact on other parts of the equipment. Sometimes submersible slurry pump　　Friction. Because if the surface of the pump is smooth when it is used, the equipment will consume less energy when it is used. Generally, the submersible slurry pump and impeller are sprayed with polymer composite materials for use　　When the pump is not in use, the pump shall be lifted away from the water source in time to drain the accumulated water in the pump, especially in cold winter. Then put it in a dry place. Conditional users can also apply oil to the key parts of the water pump and add lubricating oil to the bearing to prevent parts from rusting. in addition

　　What is the cause of pump overload.　　 Mechanical seal: mechanical seal is generally used when the sealing requirements are relatively high especially in the chemical industry. It is not only required that the slurry should not leak, but also not allowed to enter the pump body. The disadvantage of mechanical seal is high cost and difficult maintenance.　　 First of all, most of the pumps are suitable for conveying some relatively clean media, and their impellers are generally in a closed state. However, one of the media conveyed by sewage pumps maydetails,　　Whether it is the pre installation inspection or the post installation commissioning inspection, the correct operating procedures must be strictly followed. Only the correct operating steps can make the product play an effective role in the use site.　　In the mud pump,PaybackHH slurry pump, the axial force is mainly composed of the pressure difference force of the liquid effect on the impeller and the gravity of the whole rolling part. The effect direction of the two forces is the same, and the resultant force is the sum of the two forces. If the submersible slurry pump is equipped with an auxiliary impeller, the liquid effect is on the auxiliary impeller　　 When starting the slurry pump, the outlet gate valve shall be (closed or slightly opened by /. Before starting the slurry pump,PaybackWater well pipeline pump, expand the pump inlet valve and close the pump outlet valve. Then start the pump. After the pump is started, slowly start the pump outlet valve. The size and speed of opening the pump outlet valve should be based on the fact that the pump does not vibrate and the motor

　　The slurry pump of underground pump can also work normally.Which one is better,　　After that, the secondary and tertiary pumps can be started successively until the final stage pump. After all the series pumps are started, the outlet valve of the final stage pump can be gradually opened. The speed of opening the valve should be controlled by the fact that the pump does not vibrate and the motor of any stage does not exceed the rated current.　　(a) The altitude shall not exceed m.　　Moreover, because the length of the long shaft is generally fixed, when it is used later, the place where it operates will also be limited. If the equipment willPayback,　　 First of all, multiple pumps need to be used in parallel or standby pumps need to be prepared.　　Pump. In addition, the submersible slurry pump is mainly characterized by 'slurry', which is wear-resistant and particle passing.　　Although the shaft seal occupies a small position in the pump, the normal operation of the pump is closely related to the shaft seal.
