selection of pump head: generally, the pump head shall be determined by enlarging the margin of % - %.　　Balance of.Lalima,　　 The sealing oil chamber of WQ submersible sewage pump is equipped with a high-precision anti-interference water leakage detection sensor, and a thermal element is embedded in the stator winding to automatically protect the pump motor.　　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.Melbourne Airport,　　The vertical sand pumping pump is popular with a wide range of sand pumping pump users because it is easy to move. This equipment is made of high-tech endurance data. Its service life has been greatly improved, and the maintenance frequency has been reduced, the cost has been reduced, and the income has been increased.　　The type selection design of submersible slurry pump has a great impact on the service life and operation stability of slurry pump. A scientific and reasonable model selection design will affect whether your slurry pump can achieve the best efficient operation.　　When the pump is not in use, the pump shall be lifted away from the water source in time to drain the accumulated water in the pump, especially in cold winter. Then put it in a dry place. Conditional users can also apply oil to the key parts of the water pump and add lubricating oil to the bearing to prevent parts from rusting. in addition

　　Submersible slurry pump In addition it must be used continuously during transportation. If there is an interval in the middle, it must be avoided that the interval is relatively long, so as to avoid the solidification of slurry in the pump when the operation is stopped.　　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.　　Whether it is the pre installation inspection or the post installation commissioning inspection, the correct operating procedures must be strictly followed. Only the correct operating steps can make the product play an effective role in the use site.Workshop cost,　　The solution to the excessive temperature of the water pump: when selecting the motor it is necessary to select one that matches its power and speed. In addition, the cooling fan should be installed on the main shaft. It is also possible to appropriately increase the number of fan blades, but pay attention to adjusting the vacuum pump　　 The gas inadvertently entered in the equipment is discharged and good sealing performance is ensured.　　 It is also possible that the fan blades of the pump are few and the air volume is insufficient,LalimaWQ submersible sewage pump, resulting in poor heat dissipation effect.

　　 First of all, we need to know that submersible pumps generally operate in water. In fact, most of the pumps are suitable for conveying some relatively clean media, and their impellers are generally in a closed state. However,LalimaVertical heavy-duty slurry pump, one of the media conveyed by sewage pumps maytechnological innovation,　　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.　　In order to maintain the original treated water volume without increasing the number of water pumps, the liquid level in the storage tank can be increased by adjusting the floating ball in the liquid tank. After the liquid level in the storage tank is increased, the he QE curve of the device must move to the right. At this time, the head at the intersection of the two curves becomes smaller and the flow remains　　It is located in the middle, so it seems that many regions have good effects when using it.Lalima, it is also possible that the temperature is too high due to the low voltage of the water pump.　　Yes, summer is the peak sales season. In addition to agricultural applications, industrial pumps have also increased in recent years.　　When the equipment is in use, the water delivered in the pump receives the friction with the surface of the pump impeller, so the pump needs to consume more energy to reduce the friction and resistance caused by the surface when it is rotating. Water will slowly overcome it as it flows
