Water flow into the bearing damages the bearing.　　 If the head of the submersible slurry pump is too low or the head is higher than the practical condition, the flow will be large and the current will rise. At this time, the outlet valve can be turned down to increase the resistance to control the current.Zakapa,　　 other requirements (cable, control box, liquid level control, etc.)　　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.Xining,　　 for screws that are too tight or rusted for a long time, the nut can be lubricated with kerosene prepared in advance,ZakapaPipeline pump, or the nut can be gently knocked with a wooden hammer and then removed. This method can also be used in slurry pumps and other places.　　The fruit is also bad; When the axial flow pump is used, its water output is relatively large, but the head is not too high,ZakapaFire deep well pump, so the effect of using the submersible slurry pump in many plain areas is also relatively good; The water output and head of the mixed flow pump are actually derived from one　　In fact it can only be opened or closed, and the action time when opening and closing is relatively short.

　　 Protective packing of shaft seal the shaft seal pump shall regularly check the sealing water pressure and water volume, check the packing and regularly replace the packing. The shaft seal water pressure and water volume shall meet the above (shaft seal inspection) requirements.　　Submersible sewage pumps are classified as one kind of centrifugal impurities and have many forms: such as submersible and dry-type. At present, the commonly used submersible sewage pumps are WQ submersible sewage pumps, and the common dry-type sewage pumps are W-type horizontal sewage pumps and WL type vertical sewage pumps. It is mainly used to transport urban sewage and feces　　Stop, then tighten the bearing seat, press down the nut,ZakapaWQ submersible pump parameters, and fix the axial position of the rotor. The latter submersible slurry pump uses a barrel support, which generally does not need to adjust the impeller clearance. Therefore, if there is a problem with the clearance in the future use, loosen the support clamp first, and say that the nut is looseTest conclusion,　　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　　Submersible slurry pump is a kind of pump used in mines. Do you know the effect and form of its shaft seal? Let&#;s have a look.　　Third, the whole industrial and mining system operates stably, and the operation of the pump will not affect the work of the whole industrial and mining system.

　　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.Respect for customers, if the pipeline can not absorb water normally you can refer to the following reasons.　　If there is a gap in the actual work, it is necessary to find out whether the model of the pipeline pump can have the self-priming , and then check the cause of the abnormal suction range of the pipeline pump and solve it.　　If the shaft seal is not properly selected, it will not only require frequent maintenance during operation, but also leak a large amount of transmitted liquid.Zakapa,　　There is no need to equip auxiliary mixing or spraying equipment, and the operation is simpler. The equipment is directly submerged for operation, without noise and vibration, and the site is cleaner.　　Ordinary vertical motor can be used without waterproof, while the motor shaft and pump shaft of submersible slurry pump are coaxial, so the motor must be waterproof and sealed, and the motor and pump can be immersed in liquid at the same time; The vertical slurry pump is an early product, and the submersible slurry pump is a newly developed product according to the market demand　　 Next, it is necessary to check the water seal. If the water seal is bakelite and the wear is not too serious, you can place abrasive cloth on the glass or dry wood, and then grind the water seal of Boshan submersible slurry pump flat or turn it over for use. However, if the thrust rubber water seal is used, when
