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.　　 In addition, the use of ° and S-shaped bends should be reduced as much as possible during the installation and design of pipelines.Semnan,　　If the flow exceeds QD, cavitation and vibration will occur which will seriously affect the service life of the pump. Therefore, the pump head shall not be too conservative when selecting the pump. It shall be as close to the actual head of the pipeline as possible. Generally speaking, it shall not exceed times of the actual head of the pipeline.　　 When stopping the operation of the submersible slurry pump, close the cock of the vacuum gauge and pressure gauge and the gate valve on the water outlet pipeline, and After that, cut off the power supply of the motor. If the temperature of the environment is low, open the square plug at the lower part of the pump body to remove the remaining water to avoid frost cracking. During operation, the maximum temperature of the bearing shall not exceed ℃, and the quantity of calcium base grease used for lubricating oil bearing shall be the same as that of the bearing bodyAd Dindar,　　The type selection planning of submersible slurry pump has a great impact on its service life and operation stability. A scientific and reasonable type selection plan will affect whether the slurry pump can achieve efficient operation. The operating power of the slurry pump is very high and the loss is small. Service life of flow passage parts of pump　　Most of the time, we don&#;t know how to choose the pump when we buy it. In fact,SemnanVertical centrifugal slurry pump, when we use it, the flow is small　　 Why does the demand for submersible slurry pumps increase greatly? From the perspective of market demand, although the number of submersible slurry pumps has not exceeded that of vertical slurry pumps, the application market of submersible slurry pump is also better than that of vertical pump

　　With the continuous development of slurry pump technology, submersible slurry pump has also responded to the market demand. At the same time, this type of pump is especially suitable for the depth where the vertical slurry pump cannot operate. Pay attention when using the equipment. The submersible slurry pump can operate if its depth is less than m, but it exceeds　　In the process of daily use, the s of these two sewage pumps are actually the same. The biggest difference between the two is that one is fixed and the other is mobile. WQ series submersible sewage pumps are generally equipped with an auto coupling device, which we call a fixed type. It is fixed in one place to cooperate with the pipeline discharge　　Rate.Test conclusion,　　 If there is no corresponding water leakage sensor, it is necessary to regularly maintain the submersible slurry pump and replace the seals.　　 We must choose to consider the actual use situation when making the selection,SemnanVertical multistage centrifugal pipeline pump, because there will be some difference between the marked head when using and the head when using. This is because the pipe itself　　The higher the specific speed of submersible slurry pump, the smaller the allowable cutting amount of impeller diameter. In addition to the sealing effect the auxiliary impeller of the submersible slurry pump can also reduce the axial force.

　　Its main features are as follows: the whole machine is a dry-type motor pump structure. The motor is protected by mechanical seal, which can effectively prevent high-pressure water and impurities from entering the motor cavity. In addition to the main impeller, it is also equipped with a mixing impeller, the cut impeller is usually used. The cut is　　Pumps　　It is longer and saves production cost. The whole industrial and mining system operates stably and will not affect the work of the whole industrial and mining system due to the operation of the pump. When the rotating speed of the submersible slurry pump cannot be changed and the lift is higher than the required equipment lift, self-priming pumps, sewage pumps, chemical pumps and other pumps can also be called pipeline booster pumps.　　The high-pressure water flows to the space occupied by the original bubble at a very high speed, forming an impact force. The metal surface of the pump was fatigued and damaged by these impacts. Cavitation is caused by air bubble rupture and material stamping due to the difference in air temperature and pressureSemnan,　　When using the submersible slurry pump, we should do a good job in all aspects of commissioning and precautions. We also need to do a good job in protecting the equipment parts and some parts of the motor. Only in this way can we avoid the impact of water and other impurities entering the motor　　 The slurry pump mainly aims at conveying flow, so the flow meter (meter) shall be installed in the operation monitoring system as far as possible to monitor whether the flow meets the requirements at any time; In the pipeline system, slag flushing system and pressure filtration dehydration system equipped with hydrocyclone, certain　　For example, in the market,SemnanSubmersible pump can pump sewage, for example, the sweeping pump, some of which have a depth of more than meters, it is not suitable to use a vertical slurry pump under such a working condition, but it is extremely easy to use a submersible slurry pump.
