K, DK series of mining and energy-saving fan impeller Direct structure, fan host body with steel, welded steel set the price of gas pressure fan, motor and impeller place where pressurized gas turbine maintenance, compact structure, the overall stability Okay. The main body has a steady flow loop device BMJ30 gas pressure fan, so the fan characteristic curve without hump and avoid dangerous surge. DK series fan of Ⅰ, Ⅱ two-stage impeller mounted near Ⅰ, Ⅱ levels of gas pressure on the fan motor, forming mutually reverse rotation of rotating structure. Fan by collectors, grade Ⅰ host Parking: pressurized blower door stop all gas users, the excess gas from pressurized gas blower vent pipe emission. Gradually reduce the fan speed, and gradually open end of the gas emission (keep the machine before the gas pressure 3500 ~ 4500 Pa). When the gas pressure drops after pressure fan 5000Pa, open pressure fan circulation pipe valve. BMJ gas pressure fan, Korla gas pressure fan, Zibo Blower Factory Co., Ltd. provided by Zibo Blower. Zibo Blower Factory Co., Ltd. (www.zibo-fengji.com) strong, credible, Shandong Zibo fan, ventilation equipment industry has accumulated a large number of loyal customers. The company better work attitude and constantly improving innovative ideas will lead Zibo Blower and you hand into the brilliant, for a better future!
