400 meters high pressure water pump head head 400 - metre high pressure water pump type selection

head and the pressure is proportional to the pressure and hm, hm 1 mpa pressure equal to 100 meters. Lift 400 m water pump belongs to high lift high pressure water pump, through the special online intelligent pump selection system selection, head of 400 meters high pressure centrifugal pump type are many, the diagram below:

400 meters high pressure water pump head is the main type of pump type selection type D horizontal multi-stage centrifugal pump and the balance of multi-stage pump, has the same performance parameters, for conveying solids 2% or less, particle 1 or less. 3 mm, solid concentration less than 5% wt, temperature of 105 ℃ or less water or similar physical and chemical property Yu Qingshui other liquid. to allow inlet pressure 0 or less. 6MPa。 Can also be by changing the material of pump ( Or the material of pump flow components) , seal form and increase the cooling system is used to transfer temperature 210 ℃ or less hot water, oil, corrosive or containing abrasive medium, etc.

D type horizontal multi-stage centrifugal pump and DP type self balancing multistage pump efficiency is higher, can meet the needs of the working condition of high head, high flow rate, are horizontal, single-suction multi-stage, sectional structure, use the recommended hydraulic model, countries with high efficiency, low operating noise, good resistance to cavitation performance, reasonable structure, long service life etc. Is a significant difference is that if there is any balance device balance ring type D horizontal pump adopts the balancing disc or drum to balance the axial force and the balance of multistage pump will reform the structure of traditional innovation, cancel the multistage centrifugal pump axial force balance mechanism, cancelled the balance device, became the balancing disk or balance drum structure D, DG multistage centrifugal pump updated products, pump efficiency than multistage water pump with category 5 - 14%.
