when using one method, there may be some errors in the measurement results. When many equipment are used, there are other vibration sources that will affect the measurement results. Therefore, in fact, it is mainly　　When the water pump is driven by electricity or diesel engine its impeller (like an electric fan) rotates wildly, thus forming a vacuum in the impeller. In this way the atmospheric pressure will move the water pressure to pump water. In fact, from a al point of view, it is to convert electrical or chemical energy into gravityJill,　　Installation method: coupling can be used for direct connection, or belt pulley can be used for connection with belt.　　 We must choose to consider the actual use situation when making the selection because there will be some difference between the marked head when using and the head when using. This is because the pipe itselfBudaors,　　 A vent pipe is installed at the bottom of the pump, so that when the pump is buried underground, water will be injected into the bottom of the slurry pump through the vent pipe, so that a sand water mixture will be formed at the bottom of the slurry pump, so that the slurry pump can be started normally. The advantage of this approach is that even if　　.　　Submersible slurry pump it fills the gap in the application of slurry pump. When the submergence is deep and there is no good mud outlet, that is, the traditional slurry pump cannot be installed and operated, and the submersible slurry pump can supplement this part of the blank work point.

　　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　　 pump room height and allowable lifting height of lifting equipment　　The mixing impeller and other main flow passage parts are made of high wear-resistant materials, which are wear-resistant, corrosion-resistant, non clogging and have strong sewage discharge capacity, and can effectively pass through large solid particles. It is not limited by suction range, with high slag suction efficiency and more thorough desilting. No auxiliary vacuum pump is required and the investment is lower. nothingDirect material,　　It can improve the mechanical efficiency to a certain extent. Moreover, the molecular structure of the coating itself has good compactness, which can well isolate the air, water and other media from the pump impeller during use, and also reduce the corrosion and rust as much as possible　　Generally,JillWQ submersible pump parameters, the diving depth of the submersible slurry pump is not more than meters,JillVertical heavy-duty slurry pump, and the operation is reliable. Why not more than meters? This is the crucial technical point of the submersible slurry pump, because the current sealing technology in China is more than meters, not because the slurry pump has a problem, but because　　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,

　　This phenomenon shows that the failure of the pump is not only a material problem, but also reminds the pump designers and producers that in addition to good working conditions, the pump should also have good corrosion resistance, high reliability and long service life. The pump shall be designed in addition to the conventional design method of fluid mechanicsExcellent quality,　　Some impurities will entangle the impeller, so generally, the open impeller will be used, so there is no need to worry about getting stuck in the process of transporting sewage.　　 Low vibration and noise, low motor temperature rise, no pollution to the environment.　　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 pressureJill,　　As an emerging product, especially filling the gap in the application conditions of the traditional horizontal and vertical slurry pumps. At present, the application of the submersible slurry pump is gradually becoming more and more widespread, especially meeting the needs of deep-water sand pumping and dredging. At present, the depth can reach meters.　　 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, it means that the pump is full　　 After each use of the equipment
