It is understood that the GSB series high-speed pump is a single-suction single-stage or two-stage horizontal high-speed pump, which is mainly composed of a pump unit, a speed increasing device, a lubrication and monitoring system, a base and a motor, etc., because the series of pumps adopt variable pitch induction wheels. And compound impeller technology, so it has the advantages of stable small flow working stability, high cavitation performance and high efficiency, and also has obvious advantages of compact structure, convenient maintenance, wide application range, good reliability and long service life. It is the development trend of centrifugal pumps in the future. The multi-stage centrifugal pump or the reciprocating plunger pump with the same parameters has the disadvantages of complicated structure, troublesome maintenance, many wearing parts and poor reliability, and thus will be replaced by a high-performance high-speed centrifugal pump.
This series of pumps has passed the appraisal organized by Zhejiang Science and Technology Commission, and has obtained the national patent, patent number is ZL96236783.8, in line with the national standard "G3215-82 general technical conditions for centrifugal pumps for refining, chemical and petrochemical processes" and the US API610 standard . It can not only replace multi-stage centrifugal pump, partial rolling pump and partial reciprocating pump, but also completely replace imported, filling the domestic gap and reaching the current international advanced level.
The main technical performance or technical indicators: flow Q = 0.5 ~ 50m3 / h; head H = 100 ~ 1000m; speed n = 4500 ~ 1900rpm; motor power N = 7.5 ~ 200KW; the minimum specific speed can reach 10 or less.
Application field and market prospect: According to the physical and chemical properties of the transport medium, the corresponding materials can be selected, such as cast iron, cast steel, stainless steel, alloy steel or the corresponding imported grade (316, 316L) alloy steel, etc., suitable for transporting acid and alkali. Liquids such as salts, salts, benzenes, liquids and waters which may contain a small amount of solid particles, and the temperature of the transport medium ranges from -200 to +300 °C. Can be widely used in petroleum, petrochemical, pharmaceutical, metallurgy, paper, electricity, food and light industry industries.
