2SK series two water ring vacuum pump

Introduction 2SK series two water ring vacuum pump the equivalent of 2 SK Series ring vacuum pumps used in tandem. Product Details 2SK series two water ring vacuum pump the equivalent of 2 SK Series ring vacuum pumps used in tandem. SK series water ring vacuum pump because only reach ultimate vacuum -700mmHg, in order to achieve a high vacuum and high vacuum pumping speed large, and in the 1980s the country has developed a series of vacuum pumps 2SK. With the advent of a new generation of 2BV and 2BE1 series of energy-saving products, 2SK series will gradually be replaced. 2SK-P1 series of two water ring vacuum pump - Air injection pump unit mainly work in absolute pressure 10 ~ 50mmHg lower, but it is less efficient at high vacuum region, for the long run can be used Roots water ring vacuum unit, so get optimum efficiency high vacuum pumping region. Main features: ? Compare SK series single-stage water ring vacuum pump, high vacuum, high vacuum pumping speed zones Features * same pumping speed, the shaft power was significantly higher than 2BV, 2BE1 series * due to structural dual impeller construction, manufacturing, maintenance is more complex, more wearing parts. Model exhaust volume (m3 / min) limit pressure power (kw) Speed ??(rpm) Water quantity (L / min) maximum diameter intake and exhaust -0.093MPa when suction pressure of not less than mmHg MPa 2SK-1.5 1.5 0.9 -730 - 0.097 4 1440 10 ~ 15 φ40 2SK-3 3 2 -735 -0.098 7.5 1440 15 ~ 20 φ40 2SK-6 6 4 -735 -0.098 15 1460 25 ~ 35 φ70 2SK-12 12 8 -735 -0.098 22 970 40 ~ 50 φ100 Note: 1, the table values ??are obtained under the following conditions: ① atmospheric pressure 0.1013MPa (760mmHg); ② water temperature 15 ℃; ③ intake air temperature 20 ℃; ④ air relative humidity of 70%. 2, the water supply of the suction pressure value -0.05MPa (-400mmHg) when the vacuum when the limit 3 can be greater than this value, performance tolerance of ± 10%.
