The packing seal, auxiliary impeller seal and mechanical seal are mainly used. Among them, the packing seal needs small leakage and is not suitable for transporting toxic, corrosive and precious liquids; The sealing of the auxiliary impeller relies on the reverse pressure of the two sealing impellers during rotation to prevent the leakage of the medium, and can also play a role in　　After that, the secondary and tertiary pumps can be started successively until the final stage pump. After all the series pumps are started, 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.Medicinhart,　　 other requirements (cable, control box, liquid level control, etc.)　　In this way, when the equipment is used again, the solvent in the pump is often less, and the power consumption is also less, and the efficiency of the pump in use is often improved, and the fact isCurepipe,　　What is the cause of pump overload.　　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　　Water pump After understanding the cause of insufficient liquid supply, we need to check whether the liquid level of the circulating liquid storage tank needs to add media to it.

　　 The rotor assembly is designed according to the actual situation,MedicinhartHH slurry pump, and the operation is more stable!　　Then start the spray pump. It is specially used for control equipment such as fire fighting, sprinkler and water curtain in high-rise and low-rise industrial and civil buildings. It is also suitable for restaurants,MedicinhartFire deep well pump, stores, warehouses, underground garages and other places. The ordinary sprinkler head can be directly installed or hung on the sprinkler pipe network　　 If the impeller of the pump is damaged after a long time of use, it will also lead to insufficient liquid supply for the pump.Respect for customers,　　Different process requirements: the motor used in the vertical slurry pump is an ordinary vertical motor, which has no waterproof . The motor of the submersible slurry pump and the pump shaft are coaxial. The motor shall be waterproof and sealed. The motor and the pump body can invade underwater at the same time.　　 The difference between the vertical slurry pump and the submersible slurry pump The working position of the vertical slurry pump is different. The vertical slurry pump is partially immersed in the pit and cannot be completely immersed in the liquid level. The submersible slurry pump can be completely immersed (including the motor part) below the liquid level; Use of motor for vertical slurry pump　　The supply of shaft seal water must be ensured. It is strictly prohibited to operate without water, otherwise the mechanical seal will be burned.

　　 If there is no corresponding water leakage sensor, the first thing we think of is water. Whether it is drinking water or coefficient water, even the polluted water in cities needs to be purified. All these require its equipment to provide services for us. Without pumps, our basic survival is a problem.　　Fire pump control cabinet generally has two control modes: one is fire hydrant control, and the other is spray pump control. The working principle of the spray pump control cabinet is that the pressure controller is designed with a normally open contact. When the pressure relay acts due to the pressure difference, the control circuit moves the main circuit　　 there is also a simple method to measure the vibration frequency of the pump by vibration method. However, when using one method, there may be some errors in the measurement results. When many equipment are used, there are other vibration sources that will affect the measurement results. Therefore, in fact, it is mainlyMedicinhart,　　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, some parts of the pump are relatively easy to be damaged, so we need to replace them regularly during use　　Check whether it needs to be replaced.　　Now you know the reason why the pump has air turbidity. In fact,MedicinhartCentrifugal slurry pump, this is a very common phenomenon. You don&#;t have to worry about it. Water pump can transport many things such as water, acid-base night and so on. It is a good means of transport.　　What stands out is the sealing of the container. The seal is easy to install and maintain liquid metal oil, stable and reliable, but the price is quite expensive.
