a pressure gauge should be installed in this system to monitor whether the pressure meets the requirements.　　 selection of raw materials for flow passage parts: the raw materials for flow passage parts of the pump can be selected according to the particle composition

　　Pressure. Therefore, shape, hardness, concentration, acid, alkali and other characteristics of the transported materials.Copenhagen,　　Belt drive bearing assembly: the bearing assembly of this series of pumps adopts cylindrical structure, which is convenient to adjust the clearance between the impeller and the front and rear guard plates, and can be removed as a whole during maintenance. The bearing is lubricated with grease.　　 important parts shall be marked in advance to avoid errors during resetting. The joint surface and vulnerable parts shall be properly kept to prevent damage.Lamu,CopenhagenLong shaft submerged slurry pump,　　Is called cavitation phenomenon.　　The hardened mud layer collapses after softening, when the equipment is used again, the solvent in the pump is often less and the power consumption is also less, and the efficiency of the pump in use is often improved, and the fact is

　　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　　Check the three-phase current with an ammeter on the control panel. If the phase power supply is found to be insufficient, the power supply of the submersible pump shall be turned off immediately. Check whether the cable connector, connection point and power switch contact are in poor contact and whether they are the main line. Check whether the circuit wiring is broken or loose, or whether the fuse is damaged or burnt out　　The production department has to spend a lot of money to maintain and update the pump every year. The pumps made of cast iron, bronze, rubber lining, stainless steel titanium alloy and other materials used in China&#;s mining, chemical and water conservancy projects on the Yellow River are prone to wear, short service life and many faultsoriginal,　　The other mechanical seal is a split seal,CopenhagenUsed pipeline pump, which can be replaced without disassembling the slurry pump.　　The balance ring is also disassembled; Then remove the last stage impeller and the key back, and the middle section including the guide vane; in addition, remove the impellers,CopenhagenAh slurry pump, the sealing of the equipment can not bear the water pressure at this depth.

　　Is called cavitation phenomenon.Welcome calls ,　　Different process requirements: the motor used in the vertical slurry pump is an ordinary vertical motor, which has no waterproof . The motor of the submersible slurry pump and the pump shaft are coaxial. The motor shall be waterproof and sealed. The motor and the pump body can invade underwater at the same time.　　 The sealing oil chamber of WQ submersible sewage pump is equipped with a high-precision anti-interference water leakage detection sensor, and a thermal element is embedded in the stator winding to automatically protect the pump motor.　　It is also necessary to clean the ventilation duct to avoid blockage.Copenhagen,　　 If the power cord is not well contacted, it will also lead to the burning of the motor.　　 strip the outer layer of the cable to expose the copper wire for to mm, gradually thin the rubber near the wire core, grind it to the oxide layer on the wire core, wipe the wire core with alcohol (or hydrochloric acid), wrap the insulation layer and sheath layer, and dry it naturally.　　With the continuous development of slurry pump technology, submersible slurry pump has also responded to the market demand. At the same time, this type of pump is especially suitable for the depth where the vertical slurry pump cannot operate. Pay attention when using the equipment. The submersible slurry pump can operate if its depth is less than m, but it exceeds
