JockCarbon steel explosion-proof pipeline pumpCharacteristics of isothermal process

　　Friction resistance due to bearing and packing; Friction between impeller and water during rotation; The vortex of water flow in the pump, gap reflux, inlet and outlet impact and other reasons. A part of the power must be consumed, so it is impossible for the water pump to completely change the power input by the power machine into effective power, in which the constant active power　　 fold the three layers in half with self-adhesive butyl tape and gradually extend to the outside of the core. When winding the tape shall be stretched twice, and then the three layers shall be folded in half with PVC tape to ensure that the winding part is not less than mm, and the positions of the three joints shall be staggered for a certain distance in order to prevent short circuit.Jock,　　 Reduce maintenance costs. After the deployment of the fire pump, it also needs to be maintained regularly. Manual maintenance requires a lot of manpower, material and financial resources, and the maintenance cost is very high. The use of cf fire control cabinet can greatly reduce these maintenance costs　　 Then tighten the compression nut on the packing gland evenly to make the liquid leak out in drops, and pay attention to the temperature rise outside the packing chamber.Koblenz,　　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.　　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,JockVertical multistage centrifugal pipeline pump,JockSubmersible pump can pump sewage, it is to convert electrical or chemical energy into gravity　　Let the medium containing some solid particles generate a certain flow rate, so that the equipment can drive the solid to flow when it is in use, so that the slurry can be transported. In terms of the principle of the submersible slurry pump, it is actually quite simple

　　 It may be that the motor power of the water pump is too large, the working current is too large, and the heat generation is too large, resulting in the high temperature of the vacuum pump.　　 Determination of lift　　 Prepare tools and materials: a set of metric box / open-end wrench, bearing puller (commonly known as triangle puller), magnetic dial indicator, outside micrometer, caliper feeler gauge, square ruler, screwdriver with handle, hammer, V-shaped irons of the same specification, clean kerosene, oil basin, cotton yarn, etc.Installation material list,　　When the equipment is in use, the water delivered in the pump receives the friction with the surface of the pump impeller, for example,JockCorrosive pipeline pump, 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.　　 In addition, but this measurement will also be affected by the surrounding noise, so in fact, this measurement is not very accurate.

　　It will burn out. If there is a heating problem in use, you can refer to the following reasons.Standard requirements,　　Submersible slurry pump Use ultrasonic method to detect whether there is cavitation in the submersible slurry pump. This method is often convenient for re detection. Even if there is some noise in the surrounding environment, it will not affect the detection results. Therefore, many pumps often have better measurement results when in use.　　The rotation direction of the impeller shall not be reversed to damage the pump body.　　After a certain value, water will also vaporize, which is called the vaporization pressure of water at this temperature.Jock,　　Balance of.　　The packing seal, auxiliary impeller seal and mechanical seal are mainly used. Among them, the packing seal needs small leakage and is not suitable for transporting toxic, corrosive and precious liquids; The sealing of the auxiliary impeller relies on the reverse pressure of the two sealing impellers during rotation to prevent the leakage of the medium, and can also play a role in　　The impeller of the submersible slurry pump may need to be disassembled for maintenance or repair during use. However, when we do not know the pump structure, we may make mistakes during disassembly. Let&#;s take a look at the correct disassembly of the impeller
