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 addition　　 Move the sand pumping site frequently. When the pump pumps sand at a fixed position and drops to a certain height, lift the submersible slurry pump and move it to the adjacent position of the previous sand pumping place to continue pumping sand, so as to move the sand pumping place back and forth for sand pumping,Nahavand,　　 If the deep well pump is not used continuously after running in the well, it should be started up once a week and run for - minutes to prevent the electric pump from being started due to corrosion.　　 The pump body (can not) bear the pressure from the outlet pipeline system. The standby pump in the warehouse should rotate (/ times a week to make the shaft bear the load and external vibration evenly. The belt CR drive is that the motor is on the (right) side of the pump from the inlet of the pump.Chaupimarca,　　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.　　This phenomenon shows that the failure of the pump is not only a material problem, but also reminds the pump designers and producers that in addition to good working conditions, the pump should also have good corrosion resistance, high reliability and long service life. The pump shall be designed in addition to the conventional design method of fluid mechanics　　Whether it is the pre installation inspection or the post installation commissioning inspection, the correct operating procedures must be strictly followed. Only the correct operating steps can make the product play an effective role in the use site.

　　In order to make the equipment perform better when it is used, but this also needs to be based on its working principle. It can not be adapted at will when it is optimized.　　Fire pump control cabinet generally has two control modes: one is fire hydrant control, and the other is spray pump control. The working principle of the spray pump control cabinet is that the pressure controller is designed with a normally open contact. When the pressure relay acts due to the pressure difference, the control circuit moves the main circuit　　Line direction pay attention to the direction of rotation. Then loosen the original compression nut of the bearing box of the slurry pump of the submersible pump tighten the adjusting screw of the bearing box evenly, and then move the rotor assembly towards the motor. Then it is necessary to check the clearance with a feeler gauge δ, When δ= A (. ~ mmHonesty is the foundation,　　The water pump is not only the water supply for the city, but also the household water purifier used in our home. There is a with pump equipment to help us purify water. In any way, it can be divided into many types, each of which has different sizes,NahavandZD slurry pump,NahavandSmall deep well pump,NahavandSubmersible pump can pump sewage, volumes and s. Therefore, many people believe that　　 Before starting the submersible slurry pump, the rotor of the rotating pump shall be smooth and even, and water shall be injected into the pump to ensure that the pump is full of water without air.　　 there is also a simple method to measure the vibration frequency of the pump by vibration method. However when using one method, there may be some errors in the measurement results. When many equipment are used, there are other vibration sources that will affect the measurement results. Therefore, in fact, it is mainly

　　Generally, 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 becausedemand,　　The premise of using this method is that the water gun must have sufficient flow during use, otherwise the effect of the submersible slurry pump may not be obvious.　　Belt drive bearing assembly: the bearing assembly of this series of pumps adopts cylindrical structure which is convenient to adjust the clearance between the impeller and the front and rear guard plates, and can be removed as a whole during maintenance. The bearing is lubricated with grease.　　During normal operation, the temperature of the motor is very high, some even as high as ℃. In this case, it is easy to burn the motor and replace it with a new one. In fact, one motor burns out at this time. Don&#;t worry about replacing it. You must find out the cause of the motor&#;s heating, orNahavand,　　The slurry pump of underground pump can also work normally.　　 Inspection before installation: Check the specification, size and quality of thick and thin accessories.　　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.
