　　 Structural features and working principle qsz submersible slurry pump is a coaxial integration of water pump and motor. During operation,SahnenWear resistant slurry pump, 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.　　 determination of model: for water pump or pump with physical and chemical medium similar to water, it is necessary to go to the relevant product catalog or sample,SahnenWQ submersible sewage pump, and make correction according to the performance table or performance curve of the model to see whether the normal working point falls in the priority working area of the pump.Sahnen,　　Shaft seal water, no dilution of pulp, good shaft seal effect. It can be used when the slurry is not allowed to be diluted.　　Head refers to the energy obtained from the pump by the unit weight of liquid output by the pump, so head refers to the effective energy obtained from the liquid output by the pump in unit time - that is, the effective power of the pump: the equation is PE= ρ GQH (W)= γ QH (W)Hague,　　Adjustment. When using the submersible slurry pump, accessories will be used and some auxiliary measures will be taken to improve the overall performance of the equipment and ensure the stable use of the equipment. Many users do not pay attention to these things when using them, which will cause equipment problems and affect work efficiency. So we&#;re using　　Whether it is the pre installation inspection or the post installation commissioning inspection, the correct operating procedures must be strictly followed. Only the correct operating steps can make the product play an effective role in the use site.　　 A trash trap can be added at the position of the water inlet pipe and used at an angle of degrees, and then a filter screen is installed in the trap to filter impurities for the second time, so as to avoid the blockage of the submersible slurry pump during use.

　　 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.　　Vertical pipeline centrifugal pump is a kind of pipeline centrifugal pump with vertical structure. There are many models of this pump. The common one is ISG pipeline centrifugal pump. This pump is also very widely used. It is often used in industrial and urban water supply and drainage, and pressurized water supply in high-rise buildings. And in the　　Auxiliary mixing or spraying device shall be equipped for easier operation. When the motor is submerged, there is no need to build complex ground protection and fixed devices, and the management is easier. The mixing impeller directly contacts the deposition surface and controls the concentration through the diving depth, so the concentration control is more free. Equipment directly submergedWork courses,　　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.　　Now you know the reason why the pump has air turbidity. In fact, such as water, oil, liquid metal, acid-base night and so on. It is a good means of transport.　　Commodity.

　　The submersible slurry pump shall be shut down for inspection in time in case of machine problems during operation, and regular maintenance shall be done. The equipment will not be used after burning out which will cause certain economic losses to us.Credit guarantee,　　Through the introduction, we learned that the submersible slurry pump can be used to transport slurry when it is used at ordinary times. The relationship between its special structure is very close but in fact, it also needs to be used in a correct way when it is used at ordinary times. Only in this way can　　The delivery flow of screw pump has nothing to do with the delivery pressure. The delivery pressure is only related to the stage of screw pump, while the flow and speed have a strict positive proportional relationship. Therefore, when it is necessary to control the conveying flow, it is only necessary to adjust the motor speed by equipped with frequency converter or realize stepless speed regulation by belt.　　 the submersible slag pump is often used to transport pulp containing solid particles, 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 faults　　The submersible slurry pump may be blocked when it is used at ordinary times. In particular, some equipment is frequently used at ordinary times, but the maintenance work is not done well when it is used, so it will be blocked after being used for a period of time　　 It may be that the motor power of the water pump is too large, the working current is too large, and the heat generation is too large, resulting in the high temperature of the vacuum pump.
