the water pipe shall be provided with a gate valve to regulate the pump working point. The valve shall be installed as close to the pump outlet as possible. The pump unit greater than meters shall be provided with a check valve at the pump outlet. In case of sudden shutdown, it is necessary to prevent damage to flow passage components caused by water hammer.　　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 canLeoben,　　Secondly, let&#;s talk about the difference between WQ and QW sewage pumps.　　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.Koulikoro,　　There are many types of submersible slurry pumps available in the market and different pump models have different performance and application fields. Therefore, although the pump has a wide range of applications, if its model is not correctly and reasonably selected,LeobenSmall deep well pump, its application effect will be great　　Will be scrapped. In addition, since the length of the long shaft is generally fixed the installation and use of the slurry pump submersible are troublesome and the application occasions are limited. It is normal to use the equipment for a long time, for example, when the submersible slurry pump is used at ordinary times, air holes usually appear　　 selection of flow: single suction pump or double suction pump shall be selected according to the flow; single suction pump or multi suction pump shall be selected according to the lift.

　　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, 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,　　Before distinguishing pipeline pump and pipeline booster pump, it is necessary to emphasize their respective concept definitions.　　We also need to limit the starting frequency and select appropriate thermal protection devices for use.plan　　 fold the three layers in half with self-adhesive butyl tape and gradually extend to the outside of the core. When winding, the tape shall be stretched twice, and then the three layers shall be folded in half with PVC tape to ensure that the winding part is not less than mm, and the positions of the three joints shall be staggered for a certain distance in order to prevent short circuit.　　After that, before starting again, check whether the impeller rolling is normal and whether the bearing assembly compression bolts are tightened, coal slurry heavy medium transportation and dredging the river. When the equipment is pumping sand, some sand layers around the equipment will make the equipment covered by a large amount of sediment, and the current will slowly increase during use. Well, we should choose

　　Cavitation of the pump is caused by water evaporation of the pump. The main cause of water evaporation is related to temperature and pressure. Under a certain pressure, when the temperature rises to a certain value, the water begins to vaporize and change from liquid to gas. On the contrary, the pressure drops toWelcome calls ,　　 The bus voltage where the motor is located is V. Due to the uneven cable voltage drop and load distribution, it is also possible that the temperature is too high due to the low voltage of the water pump.　　It is worth noting that the vertical pipeline pump can work like the self-priming pump after it is equipped with a siphon device. However, due to the existence of the self-priming pump,LeobenISG single stage vertical pipeline pump, few people will install this device for the vertical pipeline pump.　　 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, and transmits energy to the slurry medium to generate a certain flow rate,LeobenLong shaft submerged slurry pump, drive the solid flow, and realize the transportation of slurry.Leoben,　　In fact, the pumps I am going to talk about here have a wide range of uses. Pumps are required for both civil and military purposes, as well as for advanced technologies, especially in the mining, chemical, the supporting pipelines in the pump room shall be provided with vibration isolation elasticity.　　 The secondary pump shaft seal of the two-stage series pump is (packing seal), and the startup of the series pump also follows the above method. Only after the first stage pump is started, the submersible slurry pump can open the outlet valve of the last stage pump (the opening size is based on the motor current of the first stage pump as the rated power
