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,Selin Water well pipeline pump,Selin Pipeline pump, it is necessary to prevent damage to flow passage components caused by water hammer.　　 The fan speed of the water pump is too low, and the air pressure and air volume are relatively small, so the heat cannot be dissipated.Selin ,　　 The motor output of the large flow submersible pump is too high there are other electric equipment on the user&#;s site, and the user&#;s Transformer composition capacity is too small to start the submersible pump. You can use a suitable transformer or turn off other electrical equipment that meets the power consumption of the submersible pump.　　It is longer and saves production cost. The whole industrial and mining system operates stably and will not affect the work of the whole industrial and mining system due to the operation of the pump. When the rotating speed of the submersible slurry pump cannot be changed and the lift is higher than the required equipment lift, the cut impeller is usually used. The cut isTargoviste,　　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.　　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　　For example, for example,Selin Baigang deep well 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.

　　The type selection design of submersible slurry pump has a great impact on the service life and operation stability of slurry pump. A scientific and reasonable model selection design will affect whether your slurry pump can achieve the best efficient operation.　　 water　　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 powerRespect for customers,　　Extend service life. In fact, the submersible slurry pump is widely used in many lives, so it mainly plays a role in use　　With the arrival of midsummer and the intensification of the contradiction between supply and demand of kerosene which can separate the pump body from the motor, the power supply across the country has been tense again, in the second half of the year, there is still a large gap after China&#;s power balance.　　Therefore, when the pump temperature is too high, you don&#;t need to panic. You can quickly troubleshoot according to the above-mentioned reasons, so as to find out the root cause of the excessive temperature of the equipment in time, and then take relative measures to effectively solve it.

　　 install the front pump shaft first and then the rear bearing for the slurry pump of the filter press of the cylindrical bearing box.Direct labor,　　It is an auxiliary means for some on-site monitoring.　　. Check and solve the problems such as power line disconnection, cable connection, motor winding not burnt, etc.　　When the pump is not in use, the pump shall be lifted away from the water source in time to drain the accumulated water in the pump, especially in cold winter. Then put it in a dry place. Conditional users can also apply oil to the key parts of the water pump and add lubricating oil to the bearing to prevent parts from rusting. in additionSelin ,　　 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 itself　　Now you know the reason why the pump has air turbidity. In fact, this is a very common phenomenon. You don&#;t have to worry about it. Water pump can transport many things, such as water, oil, liquid metal, acid-base night and so on. It is a good means of transport.　　 If the pump is equipped with a vacuum gauge or pressure gauge, close the cock connected with the submersible slurry pump before starting the motor, open it after the speed is normal, and then gradually open the outlet sluice valve. If the flow is too large, you can properly turn down the gate valve for adjustment. Otherwise, if the flow is too small,Open the gate valve.
