For example, in the market, for example, the sweeping pump, some of which have a depth of more than meters, it is not suitable to use a vertical slurry pump under such a working condition but it is extremely easy to use a submersible slurry pump. The water pump can be used to transport and pressurize clean water without impurities, such as apartment, residence, factory water supply, water supply system, drinking water system and water treatment. In short, there are many uses.Quinn , The inner wall is corroded and the outside air is sucked in. The pipeline pump packing is worn or the packing is not compacted. The slurry pump should be 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 and prospecting on board; What are the advantages of the submersible slurry pump? The advantage of the submersible slurry pump is that it is convenient and flexible, easy to operate and submergedCorovode, So it has a process of water diversion and exhaust. There are usually two ways to inject water into equipment. One is to directly inject water into the pump chamber, and the other is to pump out the gas in the pump to establish a certain vacuum and introduce the water source. 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 Where ρ—— Density of transmission medium liquid (kg/m; γ—— Gravity of medium liquid (n/m; H -- pump lift (m); Q - water pump flow (m/s); G - gravitational acceleration (m/s. The difference between the shaft power P and the effective power PE is the power loss in the pump which is measured by the pump efficiency. The pump efficiency is the ratio of the effective power and the shaft power, which is measured by η Indicates.
We also need to limit the starting frequency and select appropriate thermal protection devices for use. WQ submersible sewage pump adopts a unique single or double vane impeller structure, which greatly improves the sewage passing capacity, and can effectively pass through times the diameter of the pump and solid particles with a diameter of about % of the diameter of the pump. Then unscrew the nut at the front end of the pump shaft, remove the cover plate, and press out the middle impeller and water seal.Quality inspection report,Quinn Screw deep well pump, If the pump is equipped with a vacuum gauge or pressure gauge, close the cock connected with the submersible slurry pump before starting the motor, open it after the speed is normal,Quinn Submersible non clogging sewage pump, and then gradually open the outlet sluice valve. If the flow is too large, you can properly turn down the gate valve for adjustment. Otherwise, if the flow is too small,Open the gate valve. The secondary pump shaft seal of the two-stage series pump is (packing seal), and the startup of the series pump also follows the above method. Only after the first stage pump is started, the submersible slurry pump can open the outlet valve of the last stage pump (the opening size is based on the motor current of the first stage pump as the rated power For example, concentrate and tailings are treated in the concentrator, slime and dense medium coal are transported in the coal preparation plant, ore slurry %; It can be operated in series according to the needs of users.
In the application of pumps, the first thing we think of is water. Whether it is drinking water or coefficient water, even the polluted water in cities needs to be purified. All these require its equipment to provide services for us. Without pumps, our basic survival is a problem.Promise and keep promise, Start the priming pump. Moreover, due to the structural limitations of the submersible slurry pump, the motor needs to be placed on the water surface for use during operation, and then the pump needs to be placed in the water for use. Therefore, the submersible slurry pump must be QW (WQ) non clogging submersible sewage pump QW (WQ) non clogging submersible sewage pump IV. the submersible sewage pump uses V power supply, which should be three-phase power supply. If the submersible pump has only two-phase power supply it will not start. In this case, a professional electrician should be asked to use a clamp on ammeter or a submersible pump control Stability and reliability of seals between pump bodies.Quinn , Structural features and working principle qsz submersible slurry pump is a coaxial integration of water pump and motor. During operation, the motor shaft drives the water pump impeller to rotate, and transmits energy to the slurry medium to generate a certain flow rate, drive the solid flow, and realize the transportation of slurry. The installation of submersible slurry pump is a step that needs to be concerned. Since we all care about it, make sure that the liquid in the submersible slurry pump is completely discharged. If the rotor is disassembled, drain the lubricating oil in the rotor bearing housing. If the newly added oil is stored, it should continue to be used after maintenance. Do not dump it directly
