When the power supply voltage is too low, the pump will be overloaded, it may be lower than the rated voltage, so the current in the stator winding will also be Discount. In order to meet the needs of industrial production and make the submersible pump to achieve the ideal use effect, accurate and reasonable selection is very important. In order to select the pump reasonably and correctly, the following aspects need to be considered: Selection of shaft seal form: shaft seal of submersible slurry pumpFushkruger, particle size (maximum and minimum) mm When this type of pump is used at ordinary times, the pump and motor operate in a coaxial whole. When it runs, the motor shaft will drive the impeller of the pump to rotate, and then at this time, the rotating force can be brought to the medium, so thatRankweil, In the mud pump, the axial force is mainly composed of the pressure difference force of the liquid effect on the impeller and the gravity of the whole rolling part. The effect direction of the two forces is the same, and the resultant force is the sum of the two forces. If the submersible slurry pump is equipped with an auxiliary impeller, the liquid effect is on the auxiliary impeller Submersible slurry pumps are mainly used in mining, metallurgy, coal, environmental protection, electric power and other industries to transport corrosive solid particle slurry. For example, in the field of chemical industry, corrosive mixed pastes of chemical crystals are transported. Electric ash removal, coal washing plant slurry transportation,FushkrugerBooster pipeline pump, etc. Submersible slurry pump blade 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)
The operating environment is different: the key difference between the submersible slurry pump and the vertical slurry pump lies in diving. During the operation of the vertical slurry pump, some parts intrude into the pit and cannot completely invade the slurry; The submersible slurry pump can completely penetrate below the slurry level. total depth of well or pool M The slurry pump of underground pump can also work normally.market, 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. Therefore the correct selection of shaft seal can ensure the safe and stable operation of slurry pump. 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 above is about how to replace the water seal of Boshan submersible slurry pump. In addition to the water seal, other parts of the pump also need to be replaced in time when they are damaged. Moreover, so we need to replace them regularly during use Check whether it needs to be replaced.production install a valve to inject water at the water inlet and outlet. This method is to install a valve on the water inlet pipe of the submersible slurry pump and connect the water pipe to inject water into the pump. This is a common and simple method. the experimental water shall meet the relevant process requirements. Balance of.Fushkruger, the secondary and tertiary pumps can be started successively until the final stage pump. After all the series pumps are started After that, the outlet valve of the final stage pump can be gradually opened. The speed of opening the valve should be controlled by the fact that the pump does not vibrate and the motor of any stage does not exceed the rated current. Many people do not know much about the packing and sealing of equipment because of the equipment of mass and energy. Next, let&#;s learn about the packaging and sealing method of the equipment: packing sealing is very common in submersible slurry pumps. This method has good sealing performance, and effectively reduces the wear of the host and anti vibration kinetic energy Stability and reliability of seals between pump bodies.
