We must choose to consider the actual use situation when making the selection, because there will be some difference between the marked head when using and the head when using. This is because the pipe itself　　The slurry pump of underground pump can also work normally.Half way tree,　　During normal operation, the easier it will operate. However if the slurry pump reverses, it will directly cause the impeller of the slurry pump to fall off. The slurry pump must be disassembled and then re inspected, installed and tested.　　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.Kisvarda,　　The direction of the differential pressure force is opposite, which can offset part of the axial force and prolong the service life of the bearing.　　Second, the power used is not matched, so the motor temperature will be too high after long-term overload operation; In addition, frequent startup during use will also lead to fever, so I　　Compared with the vertical slurry pump, the application market is also larger. In addition to the existing industrial and mining applications of the vertical slurry pump, the submersible slurry pump can also be used as a mobile slurry pump such as sand pumping on board, prospecting, the outlet pipe of the submersible sewage pump does not flow or does not flow. After relevant research and ysis, we believe that there are many reasons for the following abnormalities of the sewage pump.　　Reasonable.Respect for customers,　　Basically, the reasons for the motor heating of the submersible slurry pump are the above items. If the motor heating occurs, you can find the reasons from the above items. However, it must be noted that if the fault is caused by electricity, people who do not know electricity should not repair it by themselves, so as to avoid people　　After the submersible slurry pump leaves the factory, there is generally only outgoing cable, and the user needs to connect it separately during installation. If the connection is wrong, it will seriously affect the normal operation of the pump, so we should follow the correct steps to connect.　　Water pump After understanding the cause of insufficient liquid supply, we can solve the problem: First, the water consumption will increase. Therefore,Half way treeVertical multistage centrifugal pipeline pump, it is necessary for us to choose a suitable water pump.packing,　　 The fixing method of the impeller is changed from screw thread to key clamp to prevent the impeller from falling off and causing damage!　　Attachment: data sheet required for ordering deep well pump　　Wheel,Half way treeZD slurry pump, mixing impeller and other main flow passage parts are made of high wear-resistant raw materials, which are wear-resistant, corrosion-resistant, non clogging, and have strong sewage discharge capacity, and can effectively pass through large solid particles. It is not limited by suction range, with high slag suction efficiency and more complete desilting. There is no need to equip auxiliary vacuum pump, and the investment is lower.Half way tree,Half way treeBaigang deep well pump,　　 In addition, the noise method directly detects the noise of the equipment in the detection process, but this measurement will also be affected by the surrounding noise, so in fact, this measurement is not very accurate.　　The pump should be divided into two aspects: electricity and machinery. As for machinery, you can compare the previous maintenance records. The second is electricity. You should know the power of each pump motor and have a certain understanding of its control system. Slurry pump with mechanical seal　　The impeller of the submersible slurry pump may need to be disassembled for maintenance or repair during use. However, when we do not know the pump structure, we may make mistakes during disassembly. Let&#;s take a look at the correct disassembly of the impeller
