The purpose is to inject liquid higher than . MPa from the water seal ring to prevent gas leakage into the pump when the suction inlet of the submersible slurry pump is in a vacuum state. When the water pressure in the pump is higher than . MPa, the sealing fluid .-. MPa higher than the pressure in the pump can be injected to seal and reduce leakage　　Second the service life of the flow passage parts of the pump is relatively long,RaleighVertical heavy-duty slurry pump, saving production costs.Raleigh,　　 The pump without self circulation cooling device shall not be exposed to the water surface for a long time to prevent the electric pump from overheating and damage.　　Stability and reliability of seals between pump bodies.Quebec-City,　　 in addition, the noise method directly detects the noise of the equipment in the detection process, but such measurement will also be affected by the surrounding noise, so in fact, such measurement is not very accurate.　　 When starting the slurry pump, the outlet gate valve shall be (closed or slightly opened by /. Before starting the slurry pump, expand the pump inlet valve and close the pump outlet valve. Then start the pump. After the pump is started, slowly start the pump outlet valve. The size and speed of opening the pump outlet valve should be based on the fact that the pump does not vibrate and the motor　　 drainage and water injection with vacuum equipment: the self exhaust of centrifugal pump is the same as the negative pressure exhaust of vacuum pump, so the water ring vacuum pump is used for exhaust to achieve the of water inlet.

　　Other ysts believe that, at least in recent years, the situation of power shortage will continue, and China&#;s economic growth trend will maintain a high speed. Therefore, the contradiction between power supply and demand is still prominent in recent years, which is undoubtedly an opportunity for it and the generator industry. In water pumps and generators, especially　　The sub bearing and cylindrical roller bearing can bear the maximum axial and radial loads of the pump. The bearing is lubricated with grease. The two ends of the bearing body are provided with sealing end caps, labyrinth sleeves and labyrinth rings, which can effectively prevent dirt such as mineral slurry from entering the bearing, ensure the safe operation of the bearing and have a high service life.　　Ensure that the service time will be extended when it is used. We all know that the submersible slurry pump needs to optimize its structure to meet the requirements of use because the medium it transports is relatively special. The structure has been optimized toPackaging strategy,RaleighScrew deep well pump,　　In fact, when the submersible slurry pump is blocked during use, it will not only have a certain impact on the working efficiency of the equipment during operation, so it is also a reminder that we are using it too　　Screw it down,RaleighQuotation slurry pump, and then remove the bearing inner race, O-ring, shaft sleeve and retaining sleeve in turn.　　The submersible slurry pump may be blocked when it is used at ordinary times. In particular, some equipment is frequently used at ordinary times, but the maintenance work is not done well when it is used, so it will be blocked after being used for a period of time

　　It, generator and market formed at the beginning of construction have gradually formed a certain scale after more than ten years of rapid development. In the early stage, water pumps and generatorsretailer generators and other mechanical and electrical products were collectively moved to the phase II market for operation. With a good business environment,　　Slurry pump Inappropriate model is selected when selecting the pump. In actual use, when the load conditions do not match the model of the slurry pump, for example, the pump lift used is too high or too low, which will lead to overload, so we are selecting the pump　　 The motor output of the large flow submersible pump is too high, there are other electric equipment on the user&#;s site, 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 pumpRaleigh,　　The seal cannot bear the water pressure at this depth. Once the water leaks, the motor will not work normally, resulting in damage to the submersible slurry pump. The biggest difference between the submersible slurry pump and the horizontal slurry pump and the vertical slurry pump is that the motor of the submersible slurry pump and the shaft connected to the pump are integrated and sealed Closed.　　Circumference. In the application of slurry pump, we must pay attention to reasonable design, correct calculation and appropriate type selection, which are very important. In addition to the main wheel, a set of stirring impeller is added at the bottom of the product, which can spray the precipitated slag into a mixture of water and solid particles　　Moreover, the leaked flammable explosive and toxic liquid will cause fire, explosion and poisoning, and the consequences will be unimaginable.
