NiljihasaSubmersible sewage pumpIf you don’t take good care of it, something will happen

　　 Protective packing of shaft seal the shaft seal pump shall regularly check the sealing water pressure and water volume, keep a small amount of cleaning water flowing along the shaft, regularly adjust the packing gland, check the packing and regularly replace the packing. The shaft seal water pressure and water volume shall meet the above (shaft seal inspection) requirements.　　The submersible slurry pump shall be shut down for inspection in time in case of machine problems during operation and regular maintenance shall be done. The equipment will not be used after burning out, which will cause certain economic losses to us.Niljihasa, the liquid level in the storage tank can be increased by adjusting the floating ball in the liquid tank. After the liquid level in the storage tank is increased, the he QE curve of the device must move to the right. At this time, the head at the intersection of the two curves becomes smaller and the flow remains　　It should be /-/ between. When the packing is worn, the packing gland can be properly pressed. If it is worn too much, it should be replaced. The whole commissioning process of the submersible slurry pump mainly includes the above five tasks, which are mainly to pay attention to the details and the phenomena occurred during the operation, and timely deal with the problems in time to avoid being on duty Accidents during operation cause losses.Trani, and pay attention to the temperature rise outside the packing chamber.　　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,　　The solution to the excessive temperature of the water pump: when selecting the motor, it is necessary to select one that matches its power and speed. In addition, the cooling fan should be installed on the main shaft. It is also possible to appropriately increase the number of fan blades, but pay attention to adjusting the vacuum pump

　　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.　　And multi-stage slurry pump; Fourth, the types of slurry pump can be divided from the pump shell of slurry pump: single shell slurry pump and lecture slurry pump; Let&#;s talk more about the model classification of slurry pumps: such as ah, HH,NiljihasaWQ submersible pump parameters, m slurry pumps. These series of slurry pumps can be collectively referred to as fractional series slurry pumps because these types　　Limited. According to relevant materials, the diameter of the impeller after cutting shall not be less than % of the diameter of the standard impeller, otherwise the of the pump will have a very adverse change. After the impeller of the slurry pump is cut, the flow area in the pump body increases, which makes the flow increase after the impeller is cut.technical service,　　 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　　A large amount of lubricating oil is stored.　　 important parts shall be marked in advance to avoid errors during resetting. The joint surface and vulnerable parts shall be properly kept to prevent damage.

　　 Next, you can place abrasive cloth on the glass or dry wood, if the thrust rubber water seal is used, whenHow much is it,　　The balance ring is also disassembled; Then remove the last stage impeller and the key back, and the middle section including the guide vane; in addition, remove the impellers, middle sections and guide vanes at other levels in the same way until the submerged slag slurry　　 whether pre lubrication water tank is required　　Pump sewage submersible pump and seawater submersible pump.Niljihasa,　　During adjustment, firstly loosen the support cover, then compress the nut, and then loosen the bearing seat. After adjusting the screw,NiljihasaQuotation slurry pump, tighten the compression nut of the bearing seat evenly to make the assembly move towards the pump head. It is necessary to turn the trolley while tightening until the plate does not move. Rotate according to the pump operation　　 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.　　Moreover, because the length of the long shaft is generally fixed, it is often troublesome to install it. Therefore, when it is used later, the place where it operates will also be limited. If the equipment will
