we don&#;t know how to choose the pump when we buy it. In fact, 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 small　　 The fixing method of the impeller is changed from screw thread to key clamp to prevent the impeller from falling off and causing damage!Perra,　　 sedimentation tanks, hydropower stations, reservoirs, rivers, power plants, open caissons,　　It is also necessary to clean the ventilation duct to avoid blockage.　　 During the installation of smooth bearing components, if the installation is correct,PerraPipeline pump body, the smooth oil is appropriate, the repair is timely, and the delivery life will be long, the repair personnel should regularly repair the bearing components, check the condition of the bearings and the smooth oil, and regularly add or replace the smooth oil during the work, and the interval and write　　Second,PerraSmall deep well pump, the service life of the flow passage parts of the pump is relatively long, saving production costs.

　　 confirm whether the pressure capacity of the pipeline meets the requirements and conduct hydrostatic test if necessary.　　Consider the vertical separation level of the tail equipment.　　Strong strength and other advantages. It is widely used as a sealing device for various pumps. Place a water seal ring at the bottom of the packing box, and then place the filler.how much　　In fact, the pumps I am going to talk about here have a wide range of uses. Pumps are required for both civil and military purposes, as well as for advanced technologies, especially in the mining, chemical, metallurgical and other industrial sectors. It is a widely used general mechanical equipment. Most pumps are corroded or severely corroded　　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　　There is a difference between submersible slurry pump and sewage pump. Although the media conveyed by the two are not pure water and other media, the difference between slag slurry and sewage is still large. Let&#;s take a look at the difference between the two.

　　 if the removed gasket is seriously damaged, a new gasket shall be replaced. The removed parts shall be cleaned with kerosene before assembly.Finance Department,　　Is called cavitation phenomenon.　　IP high power motor. The submersible pump is YQS submersible motor (water filling type).　　Some of them are OK. For irrigation and other purposes, in fact, we choose to use larger flow. Let&#;s take a look at the method of selecting pumps.Perra,　　 Then tighten the compression nut on the packing gland evenly to make the liquid leak out in drops, and pay attention to the temperature rise outside the packing chamber.　　 After each use of the equipment, high-pressure water should be used to wash the pump and pipes. The washing can be stopped until the water has no impurities.　　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.
