1. Pneumatic design: single-stage centrifugal blower impeller, double support;
1.1. The rotor:
Three body welding blade, wheel and wheel cover are all use high strength alloy steel make, at the same time, adopts the heat treatment process after welding, that can ensure the impeller grain size of the whole organization, and eliminate the stress after welding, so improve the safety and reliability of the impeller. After 15% above the working speed of impeller speed test, rotor precision dynamic balancing correction, ensure smooth operation.
1.2. The chassis using resin sand casting, it have a bright and clean appearance and internal organization.
1.3. Bearing:
the thrust bearing is tilting bearing , radial bearing is circular sliding bearing
1.4. With oil station and high oil tank.
1.5. Coupling: Elastic coupling.
1.6. In order to effectively remove dust accumulation on the impeller, this blower designed the water washing system, under the condition of the low speed to wash, once every 10 to 15 days.

Shaanxi Jia Hui Jia Shun Industrial Co., Ltd Was founded in 1992. It Is the centrifugal blower industry developing quickly, the strength is very strong enterprise, mainly produces sintering blower, the blast furnace blower, the gas pressure blower, converter blower, etc. Products sold throughout the country, and exported to Russia, India, Vietnam, Indonesia, Kazakhstan, Iran and other countries and regions. Main services in the industries of metallurgy, chemical industry, environmental protection etc., is China's fixed-point turbine machinery manufacturing enterprises.
We have a solid technical strength, there are 5 senior engineers, engineers, 30 people, senior technicians 26 people, technical personnel more than 40 people, currently registered more than 200 employees.
We complete processing equipment, blower industry belongs to the leading position in China. Purchases have Japanese Panasonic TA - 1400-2 sets of automatic impeller welding robot, five axis, four axis nc milling precision machining center, the impeller overall stress elimination after welding process, we built a 4.5 meters of multi-functional electric heat treatment furnace, and bought the Chinese advanced vibration suppression stress after welding equipment.
We produce sintering blower, blast furnace blower, gas booster blower, a dusting of converter blower centrifugal blower products such as more than 230 sets of annual output value in one hundred million yuan of above. In 2001 passed the ISO9001: 2000 quality system certification, in 2010 through the 2008 version of the audit.
