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.　　Submersible slurry pump In addition, the sewage pump is usually driven by a motor, which also requires some time og quantity when switching on and off, so in fact,　　The actual operating flow is too large, resulting in the following results: when the flow increases, the shaft power of the pump increases, while the efficiency of the motor remains unchanged, so the power of the input motor must increase. Excessive power makes the motor in an overloaded operation state, which may cause heating or even burn out the motor　　During the process, the equipment must be regularly maintained and overhauled to avoid blockage. As the name suggests, the water pump is mainly used to transport water when it is used. The effect of normal pumps is often better when it is used, but in fact, we use it at ordinary timesBarahani,　　 The rotor assembly is designed according to the actual situation,BrasiaSubmersible pump can pump sewage, the nut can be lubricated with kerosene prepared in advance,BrasiaVertical multistage centrifugal pipeline pump, or the nut can be gently knocked with a wooden hammer and then removed. This method can also be used in slurry pumps and other places.　　 If the hot water within ℃ is recommended, and the external tap water shall be connected for cooling during operation, otherwise the motor will not be burned due to too high medium temperature.

　　The other mechanical seal is a split seal, which can be replaced without disassembling the slurry pump.　　 Use a V insulation resistance meter to measure the insulation resistance between phases and phase to ground of the electric pump motor, and the value shall not be less than m Ω. Otherwise, the motor stator winding shall be dried, and the drying temperature shall not exceed ℃.　　 Cutting blades can be selected to cut some large block solid substances into pieces during use, so that blockage can be avoided during reuse.knowledge,BrasiaVortex pump and pipeline pump,　　 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, it is necessary to prevent damage to flow passage components caused by water hammer.　　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 input quantity is related to many factors such as the rotating speed of the submersible slurry pump, the bearing standard, the continuous working time, the number of stops and starts of the pump the surrounding environment and the working temperature. Therefore, it is necessary to gradually accumulate the experience and add smooth oil in a reasonable and timely manner.

　　Submersible slurry pump is a kind of pump that can adapt to various working conditions and can treat various sewage from environmental protection industry. Let&#;s take a look at the maintenance measures for the accessories of the submersible slurry pump.Latest quotation,　　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　　Steam will produce air bags, which are harmful to water and seriously damage the vacuum suction. In order to immediately empty the pipe, avoid balloon accumulation. The suction pipe shall be a steep slope rising to the direction of water flow, rather than an immediate vertical rise, generally exceeding ., which should be the height of the top water pipe along the pump inlet　　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.Brasia,　　The hardened mud layer collapses after softening, avoiding the phenomenon of burying the pump during use.　　There are differences.　　The two have certain commonalities. They are both submersible. As the name suggests, the pump is in an invasive state when running. The submersible slurry pump is a kind of submersible pump but generally speaking, people often say that the submersible pump refers to the clean water pump, such as the submersible pump for domestic water and farmland irrigation and pumping
