Centrifugal pump model

â…  â…¡ â…¢ â…£ The first part of the pump inlet diameter, expressed in millimeters of Arabic numerals, such as 80,100 and so on. The second part represents the pump's basic structure, features, uses and materials. Pinyin letters with Chinese prefix marked, such as S that single-stage double-suction centrifugal pump; D said multistage centrifugal pump; F said corrosion-resistant pump; Y said single-stage centrifugal oil pump; R said the hot water pump and so on. The third part, representing the lift and series of the pump, is an Arabic numeral in mH2O. The fourth part of the deformation of the product on behalf of the pump, the uppercase Chinese pinyin letters A, B, C three letters, respectively, said the Impeller after the first and second cut. For example: 250D - 60x6 said import and export of nominal diameter of 250 mm, single-stage lift of 60 meters of water column, the number of stages 6 multistage centrifugal pump. Another example: 100R - 37A said the import and export of a nominal diameter of 100mm, lift 37 meters of water column, the impeller after the first cutting of hot water centrifugal pump. Second, the IS pump model preparation: (IS pump is still a single-stage single-suction cantilever centrifugal pump) â…  â…¡ ---- III --- â…£ â…¤ Part I: on behalf of the pump's name, said IS; Part II: The diameter of the suction port on behalf of the pump, in mm, expressed in Arabic numerals. Part III: The diameter of the discharge port on behalf of the pump, in mm, expressed in Arabic numerals. Part IV: Nominal diameter of the pump impeller, in mm, expressed in Arabic numerals. Part V: Deformation of the product on behalf of the pump, with A, B, C three letters said. For example: IS65--50--160A said the inlet diameter of 65mm, the outlet diameter of 50mm, the nominal diameter of the impeller 160mm, the impeller after the first cut single-stage single suction centrifugal pump. Centrifugal pump too many models, no longer one by one, I hope you can consult the pump manual. Third, reciprocating compressors using the advantages of multi-stage compression are the following: 1: reduce power consumption to improve the economy of the compressor, the more the number, the closer the isothermal cycle, the higher the economy of the compressor. 2: to improve the utilization of cylinder volume, when the suction pressure is constant, the greater the pressure ratio, the higher the discharge pressure, due to the presence of clearance volume, the larger the volume of high-pressure gas remaining in the clearance expansion, Small, lower volumetric coefficient, thereby reducing the displacement. If the use of multi-stage compression, the more stages, the pressure ratio is smaller, the corresponding level of volume coefficient can be increased, so as to achieve the rational use of the cylinder's working volume. 3: to avoid the temperature is too high, when inhalation temperature and pressure is constant, the higher the pressure ratio, the higher the discharge pressure, the discharge temperature is higher. This will deteriorate or even undermine the performance of cylinder lubricants, speed up parts wear and reduce service life. In addition, when the gas temperature increases, the lubricating oil is easy to decompose, causing the compressor to explode when it is serious. Therefore, the final temperature is generally controlled at a lower flash point than lubricating oil 20 to 50 degrees Celsius, in the multi-stage compression, the pressure ratio is reduced, it can be avoided over-temperature. 4: reduce the role of the maximum force on the piston to improve the operation of the force uniformity.
