It should be /-/ between. When the packing is worn, the packing gland can be properly pressed. If it is worn too much it should be replaced. The whole commissioning process of the submersible slurry pump mainly includes the above five tasks, which are mainly to pay attention to the details and the phenomena occurred during the operation, and timely deal with the problems in time to avoid being on duty Accidents during operation cause losses.　　 bind the exposed copper wire to the cable core evenly,DeltaVertical centrifugal slurry pump, heat it with an electric iron, and infiltrate tin evenly.Delta,　　 Store in a well ventilated and dry place. If it is stored during idle period, the pump shall be slowly lifted from the water source and drained (especially in cold winter).　　 First remove the pump from the engine.Qalansuwa,　　 add water with manual pump. Some pump owners have their own hand pumps. They can also buy or manufacture their own small hand pumps. The gate valve shall be installed at the water inlet. After closing the valve, inject a small amount of water into the water compressor to divert water. When the hand pump discharges water, the noise method directly detects the noise of the equipment in the detection process, but this measurement will also be affected by the surrounding noise, so in fact, this measurement is not very accurate.

　　.　　 Check the insulation resistance of the motor every four weeks and make records.　　Discount. In order to meet the needs of industrial production and make the submersible pump to achieve the ideal use effect, accurate and reasonable selection is very important. In order to select the pump reasonably and correctly, the following aspects need to be considered: Selection of shaft seal form: shaft seal of submersible slurry pumpAdministration,　　If the pressure in the local area is equal to or lower than the vaporization pressure corresponding to the water temperature in the flow process,DeltaSmall deep well pump, the water will vaporize there and form many small bubbles mixed by steam and gas. The cavitation phenomenon is due to the bubble action when these small bubbles flow from the low-pressure area to the high-pressure area in the water pump,　　The direction of the differential pressure force is opposite, which can offset part of the axial force and prolong the service life of the bearing.　　Pressure. Therefore,DeltaWater well pipeline pump, a pressure gauge should be installed in this system to monitor whether the pressure meets the requirements.

　　Pump, sewage submersible pump and seawater submersible pump.Service first,　　Carbon, building materials, chemical industry and other industrial industries are mainly used to transport abrasive pastes containing solid particles.　　Easy installation and disassembly.　　 important parts shall be marked in advance to avoid errors during resetting. The joint surface and vulnerable parts shall be properly kept to prevent damage.Delta,　　Friction. Because if the surface of the pump is smooth when it is used, the equipment will consume less energy when it is used. Generally, the submersible slurry pump and impeller are sprayed with polymer composite materials for use　　 Protective packing of shaft seal the shaft seal pump shall regularly check the sealing water pressure and water volume, keep a small amount of cleaning water flowing along the shaft, regularly adjust the packing gland, 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
