Pump. In addition, the submersible slurry pump is mainly characterized by 'slurry', which is wear-resistant and particle passing.　　It is longer and saves production cost. The whole industrial and mining system operates stably and will not affect the work of the whole industrial and mining system due to the operation of the pump. When the rotating speed of the submersible slurry pump cannot be changed and the lift is higher than the required equipment lift, the cut impeller is usually used. The cut isSare,　　 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.　　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.Machachi,　　 One frequency converter with one slurry pump is adopted for installation. The specific transformation method is as follows: close the return valve,SareSubmersible sewage pump, 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. When　　With water, you can start working.　　What?

　　 If the power cord is not well contacted, it will also lead to the burning of the motor.　　Put it into water for use.　　 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. WhenQuality inspection report,　　After the submersible slurry pump adds a water gun to the support at the bottom of the submersible slurry pump, the hardened mud layer around the slurry pump will collapse rapidly under the applied water pressure, which will also increase the sand pumping area. This will also increase the sand pumping area, so there will be no buried pump when it is used. However,　　Although the shaft seal occupies a small position in the pump, and different pump models have different performance and application fields. Therefore, although the pump has a wide range of applications, if its model is not correctly and reasonably selected its application effect will be great

　　 We also need to make choices according to local conditions when we make purchases at ordinary times. For example, the head of the centrifugal pump itself is relatively high, but its water output is not very large when it is used, so it is effective when it is used in many mountainous areastechnical service,　　Work, no noise and vibration, and the site is cleaner.　　The main and feature of self-priming pump is self-priming capacity. How to improve the performance of the pump and obtain large profits requires the following points: first,SareTwo stage slurry pump,SareBaigang deep well pump, the discharge valve must be opened to start the self-priming pump, so that the gas can be discharged from the discharge port. Secondly, there should be enough liquid in the cavity of the self-priming pump, otherwise it will not　　 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. WhenSare,　　 Moreover, the processes of these two pumps are also different, and the sewage pump can generally be adjusted. Submersible pumps are generally used in some special or other places.　　Submersible pump is a common water lifting equipment for deep wells. During operation, mine rescue industrial cooling, farmland irrigation, seawater lifting, ship load adjustment, landscape fountains, etc. Submersible pump is generally divided into clean water submersible　　At the same time
