Although the shaft seal occupies a small position in the pump, the normal operation of the pump is closely related to the shaft seal.　　Function of shaft seal of submersible slurry pump: the main of shaft seal is to prevent high-pressure liquid from leaking out of the pump and prevent air from entering the pump.Linz Airport ,　　The submersible sewage pump is a kind of pump product which is connected with the motor and works under the water at the same time. Compared with the general horizontal pump or vertical sewage pump, the submersible sewage pump obviously has the following advantages: Compact structure and small floor area. Submersible sewage pump is submerged　　Most of the time, we don&#;t know how to choose the pump when we buy it. In fact,Linz Airport Pipeline pump, we only need to choose the appropriate equipment according to our own use needs when we choose it. It&#;s more like that in a conventional family, when we use it, the flow is smallSan-Jose-de-las-Lajas,　　 determination of model: for water pump or pump with physical and chemical medium similar to water, and make correction according to the performance table or performance curve of the model to see whether the normal working point falls in the priority working area of the pump.　　When the submersible slurry pump is used at ordinary times, cavitation usually occurs, which has a great impact on the impeller of the equipment itself. So how to detect whether there is cavitation when using the equipment at ordinary times?　　Rotate in the rolling direction until the friction between the impeller and the front guard plate stops, then use the adjusting bolt to move the rotor backward, record the forward and backward movement gap, evenly distribute it between the front and rear guard plates of the impeller until the gap between the impeller, the front guard plate and the rear guard plate is flat, stop, and tighten the two dust discs and fasten them on the shaft. adjustment

　　It is also necessary to clean the ventilation duct to avoid blockage.　　Transmission type: direct drive, parallel belt drive, upper and lower belt drive,Linz Airport Single suction slurry pump, CV vertical belt drive, etc. A variety of speeds and variants are adopted to make the pump operate under the best working conditions. It has long service life and high operation efficiency, and can meet many kinds of harsh transportation conditions.　　 The rotor assembly is designed according to the actual situation, and the operation is more stable!demand,Linz Airport ZD slurry pump,　　For example, it has a great impact on the impeller of the equipment itself. So how to detect whether the equipment has cavitation during use?　　Rotate in the rolling direction until the friction between the impeller and the front guard plate stops, then use the adjusting bolt to move the rotor backward, record the forward and backward movement gap, the front guard plate and the rear guard plate is flat, stop, and tighten the two dust discs and fasten them on the shaft. adjustment　　 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.

　　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.Scheme customization,　　 When starting the slurry pump, the outlet gate valve shall be (closed or slightly opened by /. Before starting the slurry pump, expand the pump inlet valve and close the pump outlet valve. Then start the pump. After the pump is started, slowly start the pump outlet valve. The size and speed of opening the pump outlet valve should be based on the fact that the pump does not vibrate and the motor　　Fire fighting awareness is deeply rooted in the hearts of the people. With the improvement of fire fighting awareness, many people pay more and more attention to fire pumps. Some places also began to pay attention to the selection of fire pumps. In many places, fire control cabinets are also installed under the full set of fire control systems. In earlier years, complete protection s, reasonable structure, convenient installation and high cost performance. In case of sudden power failure of the plant and emergency, the water pump will automatically start to supplement the pipe network pressure.Linz Airport 　　After that, before starting again, check whether the impeller rolling is normal and whether the bearing assembly compression bolts are tightened, and then start the pump.　　It is occasionally found that there is insufficient liquid supply when using, so what are the reasons for this situation and how to deal with it.　　What is the order.
