Backing plateVortex pump and pipeline pumpOn new trends

　　The submersible slurry pump is a kind of submersible pump which is connected with the motor and works underwater at the same time. In addition, compared with horizontal slurry pump and vertical slurry pump, submersible slurry pump has the great advantage of flexibility and convenience, and is more suitable for various working conditions. The important technical points of submersible slurry pump are its motor and　　Where ρ—— Density of transmission medium liquid (kg/m; γ—— Gravity of medium liquid (n/m; H -- pump lift (m); Q - water pump flow (m/s); G - gravitational acceleration (m/s.　　The difference between the shaft power P and the effective power PE is the power loss in the pump, which is measured by the pump efficiency. The pump efficiency is the ratio of the effective power and the shaft power, which is measured by η Indicates.Backing plate,　　Or the liquid contains fibers. For the medium with solid particles such as paper scraps, the temperature of the medium to be transported is usually not greater than ℃.　　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.Ibarra　　Different installation requirements: the vertical slurry pump needs to be fixed, while the submersible slurry pump does not need to be fixed. It can directly invade into the liquid for operation.　　The motor is scrapped. Moreover, because the length of the long shaft is generally fixed, the installation and use of the pump is troublesome, and the application occasions are subject to many restrictions.　　 bind the exposed copper wire to the cable core evenly, heat it with an electric iron, and infiltrate tin evenly.

　　Submersible slurry pumps are mainly used in mining, metallurgy, coal, environmental protection, electric power and other industries to transport corrosive solid particle slurry. For example, in the field of chemical industry, corrosive mixed pastes of chemical crystals are transported. Electric ash removal, coal washing plant slurry transportation, etc. Submersible slurry pump blade　　Secondly, let&#;s talk about the difference between WQ and QW sewage pumps.　　Limited. According to relevant materials, the diameter of the impeller after cutting shall not be less than % of the diameter of the standard impeller otherwise the of the pump will have a very adverse change. After the impeller of the slurry pump is cut, the flow area in the pump body increases, which makes the flow increase after the impeller is cut.Where can I find it?,　　Be sure to choose a pump that is more suitable for use.　　If the shaft seal is not properly selected, it will not only require frequent maintenance during operation, but also leak a large amount of transmitted liquid.　　Potential energy, once the pump can not absorb water, the equipment is shaped like a decoration,Backing plateSewage pump diving, so what is the reason for this situation? How to solve it?

　　The structure of the submersible slurry pump will be more intuitive. First, the equipment will use centrifugal force to drive the liquid from the impeller to the outer edge and obtain energy, and then leave the edge of the impeller at a higher speedTest results,　　The balance ring is also disassembled; Then remove the last stage impeller and the key back, and the middle section including the guide vane; in addition, middle sections and guide vanes at other levels in the same way until the submerged slag slurry　　Consider the vertical separation level of the tail equipment.　　Do not exceed the rated current.Backing plate,　　 There is also a vibration method to measure the vibration frequency of the pump, 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　　 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,Backing plateUsed pipeline pump, it is necessary to prevent damage to flow passage components caused by water hammer.　　Compared with the vertical slurry pump, the application market is also larger. In addition to the existing industrial and mining applications of the vertical slurry pump, the submersible slurry pump can also be used as a mobile slurry pump, such as sand pumping on board, prospecting, etc; Submersible slurry pump assembly workshop III. what are the advantages of submersible slurry pump
