So that you can apply mixed flow pumps more strongly, our company will bring you some professional knowledge about maintenance and repair of mixed flow pumps.
In the first place, how to maintain a mixed flow pump that is not used. When your mixed-flow pump is at the end of its service life, you should immediately protect the mixed-flow pump from water resources. The price of the mixed-flow pump exhausts the water stored in the pump, especially in winter, and then place it in a dry area. If there is a standard, it is best to coat the key parts of the mixed flow pump with unsalted butter, and add grease to the rolling bearings to prevent the parts from rusting. On the other hand, if the mixed-flow pump is not used for a long time, it will actually cause necessary damage to it, which will cause rusting of parts and accessories, and the price of the mixed-flow pump will shorten the life of the centrifugal pump.
For the usual maintenance of mixed-flow pumps, manufacturers of mixed-flow pumps should click here to do the following procedures: 1. The inspection basis must be supplemented with filling materials; 2. Clean the external environment of the mixed-flow pumps, check the rolling bearings and properly lubricate; 3. Check the company Shaft device, air release valve and external tightening conditions. Some areas that must be adjusted are generally: centrifugal impeller clearance (0.37-0.78); parallelism of pump shaft and motor; coupling clearance.
Some areas that must be replaced are generally: 1. fillers; 2. rolling bearings; 3. pump shafts; 4. buffer blocks.
Aiming at the maintenance level of the mixed-flow pump, the manufacturer of the mixed-flow pump is concerned that if the mixed-flow pump has a common fault, do not disassemble it by hand. When self-assembling and disassembling, it is very easy to cause the following two problems: First, if you do n’t know where the common faults are, you may blindly follow the trend; second, there are no tools and thus harm the original intact parts. The effective method is to go to the after-sales service center with working experience and business scale for overhaul, and immediately replace the over-age parts and some parts. Under normal circumstances, the centrifugal pump should be overhauled for six months to avoid working with "illness".
After the mixed-flow pump is put into practice, press the pump seat in place, and finely adjust the level of the three pump seats so that they are on the same level surface. (3) Mechanical and electrical engineering installation: First, remove the mechanical and electrical engineering coupling pin on the pump, and place them on the mechanical and electrical engineering bearing end cover. Centrifugal water pump according to place: Connect the centrifugal water pump that the manufacturer has set according to its place in the pump base. Put the water inlet and the inlet flange of the pump well, and put a layer of eraser pad in the middle of the delicate flange.
Submersible axial flow pump research plan and standard value model. CFD explained that it can be used in the deep submersible mixed flow pump hydropower generation scheme to reduce the cycle time principal of the scheme. Through the entire process of simulating flow patterns and statistical data interpretation, select a good hydropower generation model. ) The larger the number of deep submersible mixed flow pump leaves, the higher the total flow at the solution point and the higher the pump lift, the greater the speed of the centrifugal impeller outlet value, the lack of hydropower generation, and obedience. According to two centrifugal impellers and four guide vane schemes, 8 hydropower schemes were obtained.
