namur Fire deep well pumpHigh quality merchants

　　Water or air leakage in the pipeline. The nut may not be tightened during installation. If the leakage is not serious, tighten the nut with a wrench. as　　Carbon, building materials, chemical industry and other industrial industries are mainly used to transport abrasive pastes containing solid particles.namur ,　　 Store in a well ventilated and dry place. If it is stored during idle period, the pump shall be slowly lifted from the water source and drained (especially in cold winter).　　What stands out is the sealing of the container. The seal is easy to install and maintain, stable and reliable,namur ISG single stage vertical pipeline pump, but the price is quite expensive.Spanish-town,　　What is the solution to this situation?　　Fourth, model selection parameters: outlet diameter,namur Rubber lining submerged slurry pump, flow, dust, motor power, impeller speed, pumping rate, maximum particle and weight.　　 If there is abnormal sound inside the slurry pump and there is no water, it is likely that the equipment may have air infiltrating into it when absorbing water, which will cause abnormal sound inside the pump, and then at the same time, the impeller is damaged or the impeller is damaged

　　The premise of using this method is that the water gun must have sufficient flow during use, it is necessary to use the fire control cabinet. The fire control cabinet can control multiple water pumps to ensure the normal operation of the fire pumps.　　The submersible slurry pump is a slurry pump which is connected with the motor and works under the water at the same time. Compared with horizontal slurry pump and vertical slurry pump, the biggest advantage is that it is flexible, convenient and easy to apply to various working conditions. The most important technical point of submersible slurry pump is the tightness between its motor and pump body Stability and reliability of seals.Quality improvement,　　 When the slurry pump fails to absorb water during operation, it may also be because the bottom valve is not opened. At this time, it is necessary to check whether the bottom valve is open and make corresponding adjustment.　　The submersible slurry pump may be blocked when it is used at ordinary times. In particular some equipment is frequently used at ordinary times,namur Wear resistant slurry pump, but the maintenance work is not done well when it is used, so it will be blocked after being used for a period of time　　If the pressure in the local area is equal to or lower than the vaporization pressure corresponding to the water temperature in the flow process, the water will vaporize there and form many small bubbles mixed by steam and gas. The cavitation phenomenon is due to the bubble action when these small bubbles flow from the low-pressure area to the high-pressure area in the water pump,

　　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 additionmiddleman　　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　　The impeller channel reaches the outer edge.　　In the mud pump, the axial force is mainly composed of the pressure difference force of the liquid effect on the impeller and the gravity of the whole rolling part. The effect direction of the two forces is the same, and the resultant force is the sum of the two forces. If the submersible slurry pump is equipped with an auxiliary impeller, the liquid effect is on the auxiliary impellernamur ,　　If the shaft seal is not properly selected, it will not only require frequent maintenance during operation
