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 faults　　Function of shaft seal of submersible slurry pump: the main of shaft seal is to prevent high-pressure liquid from leaking out of the pump and prevent air from entering the pump.Rudbar 　　 Working conditions　　 It may be that the motor power of the water pump is too large, and the heat generation is too large, resulting in the high temperature of the vacuum pump.Rustaq,　　After a certain value, water will also vaporize, which is called the vaporization pressure of water at this temperature.　　 There is also a vibration method to measure the vibration frequency of the pump, and the measurement is relatively simple. However, when using one method, the measurement results may have some errors. When using the submersible slurry pump, there are other vibration sources that will affect the measurement results, so it is actually the main　　 If the hot water within ℃ is recommended, the hot water pump must be used, and the external tap water shall be connected for cooling during operation, otherwise the motor will not be burned due to too high medium temperature.

　　Vertical slurry pump is an early product. Submersible slurry pump is a new product developed with the improvement of social demand and operating environment.　　 Shaft seal part auxiliary impeller shaft seal: through the impeller action of a reverse centrifugal force, prevent the slurry from leaking out. When the positive pressure at the inlet of the pump is not greater than % of the pressure at the outlet of the pump, the single-stage pump or the first stage pump in series can adopt the auxiliary impeller shaft seal, and the auxiliary blade shaft seal is not required　　 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,Rudbar Pipeline pump, and transmits energy to the slurry medium to generate a certain flow rate, drive the solid flow,Rudbar Self priming non clogging sewage pump, and realize the transportation of slurry.Pursuit of excellence,　　Troubleshooting: first increase the water pressure, then inject water into the pump body, and then start the pump. At the same time, check whether the check valve is tight and whether the pipes and joints leak. If air leakage is found, and tighten the screws.　　 There may also be mechanical failure of the pump, such as serious damage to the bearing of the pump, so that the bore will be 'swept' when the stator and rotor rub against each other, or the impeller will be stuck due to impurities such as water and grass when the pump pumps water　　If the submersible slurry pump cannot be installed and operated, the cut impeller is usually used. The cut issystem,　　Body. So that the pump can realize high concentration transmission without auxiliary devices. The unique sealing device can effectively balance the pressure inside and outside the oil chamber, so that the pressure at both ends of the mechanical seal can be kept balanced, which maximizes the reliable operation of the mechanical seal and greatly extends its service life　　 Drain the water filled in the motor.　　The whole packing body,Rudbar Sewage pump diving, including the packing gland, packing ring and packing, needs to be disassembled; Submersible slurry pump Disassemble the o-seal ring, shaft sleeve, balance disc and key on the shaft in turn, and then the discharge section includes the last stage guide vaneRudbar ,　　There are differences.　　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, and different pump models have different performance and application fields. Therefore so it will be blocked after being used for a period of time　　There are many types of submersible slurry pumps available in the market, although the pump has a wide range of applications, if its model is not correctly and reasonably selected, its application effect will be great
