Company website: www.henanhongjifengji.com company sales: 0394-7892627 15518086290 QQ: 445528270 future will vigorously carry out energy-blower development work. As Japan's spiral shape of the flow path and impeller made appropriate improvements, effectively preventing the generation of eddy currents and flow separation, the adiabatic efficiency increased by 5% to 10% higher than the original blower; large flow centrifugal Switzerland blowers, each level has inlet guide vanes, which also reached 82 percent efficiency varied; manufactured by Japan multistage centrifugal blowers, using inlet guide vane after continuous automatic adjustment, energy-saving rate of 20%; high-speed single-stage centrifugal blower High circumferential speed, pressure ratio, semi-open radial Impeller, its efficiency can be increased by 10%; and at the other end of the spindle is provided with exhaust turbine blower, exhaust emissions when the expansion work recovery to achieve energy saving purposes.
