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.　　 Then unscrew the nut at the front end of the pump shaft,ChittagongWear resistant slurry pump, remove the cover plate, and press out the middle impeller and water seal.Chittagong,　　 Assembly of water pump: fix the shaft and water inlet joint on the mounting base, fix the impeller and conical sleeve on the shaft with the disassembly cylinder, and then install the guide housing and impeller In this way, the upstream casing and check valve are installed in turn.　　The disc friction loss of the slurry pump impeller will decrease with the decrease of the impeller diameter, so that the pump efficiency of most low specific speed pumps will improve slightly after the impeller is cut. After cutting, keep the blades overlapped to a certain extent, and the degree of blade overlap will decrease with the addition of specific speedSanta-Ana,　　Screw it down and then remove the bearing inner race, O-ring shaft sleeve and retaining sleeve in turn.　　Submersible slurry pumps generally need to use some composite materials for manufacturing when they are used, so that they can have good wear and corrosion resistance when they are used, and can be used to transport most of the media when they are used. Phreatic slurry　　Discount. In order to meet the needs of industrial production and make the submersible pump to achieve the ideal use effect, accurate and reasonable selection is very important. In order to select the pump reasonably and correctly, the water consumption will increase. Therefore, it is necessary for us to choose a suitable water pump.　　Distance from the dynamic water level of the pool to the center of the water outlet of the pump base (m)　　In the application of pumps, the first thing we think of is water. Whether it is drinking water or coefficient water,ChittagongVertical multistage centrifugal pipeline pump,ChittagongZD slurry pump,　　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.　　In addition to the method, materials shall be selected comprehensively according to the nature of corrosive medium, anti cavitation theory, corrosion mechanism of water pump and stress characteristics. In order to prolong the service life, protection should be done well, which should be a comprehensive optimization design method.　　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.

　　 First, screw down the bolts on the side bearing pressure cap, and then remove the nuts used for the connection between the three parts: discharge section, stuffing box body and bearing body; Then screw off the round nut on the shaft, and successively install the bearing inner race, bearing gland and retaining sleeveConvenient and efficient,　　 the front and rear bearing glands are equipped with oil seals, which are padded with green paper or asbestos. There is a gap of .- mm between the rear gland and the bearing.　　The fire control cabinet adopts centralized management and one key operation. The startup procedure is simple and convenient. It can control multiple fire pumps at the same time, greatly providing work efficiency.　　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.Chittagong,　　 Cutting blades can be selected to cut some large block solid substances into pieces during use so that blockage can be avoided during reuse.　　Generally, the diving depth of the submersible slurry pump is not more than meters, 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　　There will be no insufficient liquid supply or other problems.
