3. The speed of the pump shaft speed means revolutions per minute, with the "n" indicates 200SV-SPR liquid slurry pump, the unit is r / min 4. efficiency and shaft power pumping efficiency slurry is referred slurry efficiency, with "η" said pumping water efficiency and when it has the following relationship ηm = ER η% (1-6) Where:? ER- and slurry characteristics related to efficiency reduction factor, whose value HR lift reduction factor equal under 65QV-SPR liquid slurry pump, namely HR = efficiency ERη- pumping water when the% obtained by the test product features as impurities pump technology development and improvement, combined with user feedback experience, the use of modern fluid theoretical mechanics, theory of modern machinery, computer software design; I introduced EZJ series slurry pumps, slurry pumps have the whole model in the series, the performance condition covering a wide selection of convenient features. g = EN \ t ??? ?? bidi-font-size:? 10.5pt; font-family: 'Arial', 'sans-serif'; color: # 333333; mso-font-kerning: 0pt '> V type V-belt drive has CL, CV, CR, ZL, ZV, ZR drive. Overall performance: wide performance range of the pump cavitation performance, high efficiency. Tandem technology can be used to meet the long-distance transport. There are a variety of metal wetted parts are available, and increase the depth. Using a variety of speeds and various modifications under way 150SV-SPR slurry pump liquid, causing the pump to operate at optimum mining. Long life, high efficiency, to meet the many types of bad transport conditions. Rubber impeller (FIG), under 100RV-SPR liquid slurry pump, slurry pump Co. sent by Shijiazhuang-pump.
