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.　　Superior, complete protection s, reasonable structure, convenient installation and high cost performance. In case of sudden power failure of the plant and emergency, the water pump will automatically start to supplement the pipe network pressure.Betjan,　　Attachment: data sheet required for ordering deep well pump　　If the oil seal ring of the shaft is seriously worn, replace it with a new one.Stolin,　　If the water leakage is serious, the broken pipe shall be dismantled and replaced. Lower the lift and press the nozzle of the water pump into the water for .m.　　So it is called: submersible slurry pump.　　 Then reinstall the equipment on the engine and install the rubber hose.

　　Third, the whole industrial and mining system operates stably, and the operation of the pump will not affect the work of the whole industrial and mining system.　　Transmission type: direct drive, parallel belt drive, upper and lower belt drive, CV vertical belt drive, etc. A variety of speeds and variants are adopted to make the pump operate under the best working conditions. It has long service life and high operation efficiency, and can meet many kinds of harsh transportation conditions.　　Flexibility. The equipment has advanced structure, strong sewage discharge capacity, excellent material selection and strong corrosion resistance. It is suitable for conveying liquids containing solid particles, cinder and tailings. So what are the requirements for its work? Let&#;s understand briefly.Production department,　　In addition to the method materials shall be selected comprehensively according to the nature of corrosive medium, anti cavitation theory,BetjanSplit vertical pipeline pump, 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.　　 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.　　Is called cavitation phenomenon.

　　 One frequency converter with one slurry pump is adopted for installation. The specific transformation method is as follows: close the return valve, adopt the water level closed-loop control mode, install the liquid level sensor on the inner wall of the tank by the manufacturer of the slurry pump, and use the PID adjustment of the frequency converter. WhenProduct survey,　　 Move the sand pumping site frequently. When the pump pumps sand at a fixed position and drops to a certain height, lift the submersible slurry pump and move it to the adjacent position of the previous sand pumping place to continue pumping sand, so as to move the sand pumping place back and forth for sand pumping so that the sand pumping area in this area forms a honeycomb,BetjanCirculating hot water pipeline pump,　　In terms of performance parameters, optional flow range: - (m/h), lift range: - (m), power range: .- (kw), caliber range: - (mm).　　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, 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 beBetjan,　　When the submersible slurry pump works, the pump needs to be placed on land the suction pipe needs to be placed in water, and the pump needs to be started. Due to special structural requirements,BetjanAh slurry pump, the slurry pump and submerged slurry circulating pump need to be placed above the water surface, so they need to be fixed, otherwise the motor will fall into the water　　The packing seal, auxiliary impeller seal and mechanical seal are mainly used. Among them, the packing seal needs small leakage and is not suitable for transporting toxic, corrosive and precious liquids; The sealing of the auxiliary impeller relies on the reverse pressure of the two sealing impellers during rotation to prevent the leakage of the medium, and can also play a role in　　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
