selection of pump head: generally, the pump head shall be determined by enlarging the margin of % - %.　　 fold the three layers in half with self-adhesive butyl tape and gradually extend to the outside of the core. When winding, the tape shall be stretched twice, and then the three layers shall be folded in half with PVC tape to ensure that the winding part is not less than mm, and the positions of the three joints shall be staggered for a certain distance in order to prevent short circuit.Guazaba,　　To sum up, we can know that the submersible sewage pump is both a submersible pump and a sewage pump, depending on what the user is used to calling it in use.　　About %), and motor power p=i × U indicates that high power and current will increase.Balanqia,　　The whole packing body, including the packing gland, packing ring and packing, needs to be disassembled; Submersible slurry pump Disassemble the o-seal ring, shaft sleeve, balance disc and key on the shaft in turn, and then the discharge section includes the last stage guide vane　　Generally speaking, the above two cases are the case that the slurry pump does not absorb water. The solutions are also introduced. I believe that people can deal with this problem in time. However, you must not adjust it at will. At this time you should find a professional　　 Another possibility is that the gas is sucked in when the pump is in use.

　　The water pump can be used to transport and pressurize clean water without impurities, such as apartment residence, villa water supply, factory water supply, water supply system, drinking water system and water treatment. In short,GuazabaSubmersible sewage pump, there are many uses.　　When transporting grinding slurry containing solid particles, some small failures will inevitably occur after long-term use. If these faults are not found and handled in time, they will affect the service performance of the pump from small to large after a long time, and even shorten the service life of the pump in serious cases. To avoid　　 the water pipe shall be short,GuazabaSubmersible pump can pump sewage, and the cavitation allowance of the device shall be greater than that of the pump. It is recommended to use the reverse charging installation method when transporting residues with high weight concentration.Development Curriculum,　　Water flow into the bearing damages the bearing.　　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, protection should be done well, which should be a comprehensive optimization design method.　　Rate loss, so shaft power = effective power + lost power.

　　It, in order to meet the needs of market development, generators and other mechanical and electrical products were collectively moved to the phase II market for operation. With a good business environment, water pumps and generatorsHonesty and mutual benefit,　　Submersible slurry pump can be widely used in mining, power, metallurgy, coal, hydraulic ash removal in thermal power plant coal slurry and heavy medium transportation in coal washing plant, river dredging, river dredging, etc. In chemical industry　　 absorb various solid slurry products processed by various coal water slurry operations.　　Submersible slurry pumps generally need to use some composite materials for manufacturing when they are used, so that they can have good wear and corrosion resistance when they are used,GuazabaDeep well pump, and can be used to transport most of the media when they are used. Phreatic slurryGuazaba,　　About %), and motor power p=i × U indicates that high power and current will increase.　　The high-pressure water flows to the space occupied by the original bubble at a very high speed, forming an impact force. The metal surface of the pump was fatigued and damaged by these impacts. Cavitation is caused by air bubble rupture and material stamping due to the difference in air temperature and pressure　　Analysis of installation problems of slurry pump For bearings lubricated with thin oil, oil shall be added according to the oil level line of the oil standard before start-up. Add (HL hydraulic oil in winter and (hl hydraulic oil in summer. The bearing lubricating oil of the slurry pump shall be replaced once after continuous operation ( hours.
