Blower Fan Centrifugal
Series B Single-stage High-speed Centrifugal Blower is the new product which designed by Shandong Zhangqiu BlowerCo., Ltd and Xi'an Jiao Tong University .The pneumatic performance and structural design of the series of products hasreached the advanced level of similar products at home and abroad. The blowers are widely used in sewage water treatment,metallurgy, fluidization of circulating fluidized bed boiler in power station, exhaust gas desulphurization, pharmacy, gasbooster and so on.
The blowers are adopted axial air-inlet guide vane, flow capacity control range is the rated flow capacity of 60% to 110%so operating efficiency of blower is also high at non-rated condition. And the blowers are adopted anti-surge device, it canavoid the blower surge effectively.
The blowers are adopted integrated structure of assembly-type, in details, the blower body is assembled on the casing ofgear accelerating box, the lubricating oil system distributed ,the motor and gear accelerating box are installed on the commonpedestal compactly;the pedestal doubles as a oil tank.
The Moment of inertia of rotor is small, the startup and stop time has been decreased and the oil box with high oil leveland accumulator has been abrogated. Compared with the multistage centrifugal blower of same flow capacity and pressurethis product enjoys low energy consumption, light weight and small size.
The parameters (such as bearing vibration of whole machine, temperature rise, inlet and outlet pressure and temperatureanti-surge control; start of the interlock protection; failure alarm; oil pressure of lubricating system, oil temperature controland so on) are controlled by programmable logic controller that can be get real-time control. The whole machine has no easyworn parts and the daily maintenance is convenient.
The lubrication system is consists of the oil tank and the oil pipeline.The pedestal doubles as a oil tank, the immersion-type electric heater and temperature control switch are both included in the oil tank. The oil pipeline is composed of the mainoil pump, the electric pump,the double cylinder oil filter etc. The main oil pump would be driven by the low-speed gear andit supplies the pre-lubrication to gear and bearing with certain pressure when the units operate normally, The electric pumpwould supply the pre-lubrication before the units start and keep the oil pressure still under the emergency and downtimeThe electric pump also plays a role of stand-by oil pump. The oil filter with double cylinder is high-precision. The pressuredifference alarm device on filter is also equipped.
Shandong Zhangqiu Blower Co., Ltd is one of the most important blower manufacturers in China with 50 years of experience inR&D and production of Roots type blower, it has become the largest manufacturer and seller of Roots type blower. it has invested to set yp two Chinese-Japanese joint ventures, one sub-company in USA which is the first oversea organization in domestic blowersindustry. Now the company has become a large-scale modern producing and design enterprise with products of blowers, heavy-duty equipments, pneumatic conveying systems, industrial pumps and electric equipments, etc.
Geared Turbo Blower is developed by technical authority of Beijing University of Aeronautics and Astronautics. Integrating all resources those representing the highest level of aerospace field in China in the Research, Technology, Production, Manufacturing. This Geared Turbo Blower’s aerodynamic performance and structure design achieves the worldwide advanced technology level.
Features:
1.Applying ternary theory design with high efficiency of 82%
2.Applying axial inlet guide vanes and a diffuser regulating device, flow regulation range can be the 45% to 110% of the rated flow, and get the higher efficiency in the off-rating operation conditions.
3.Applying integral structure design, blower body is assembled on the casing of the gear box, lubricating system, motor, and gear box are assembled on a common base which is also used as oil tank.
4.Applying strict dynamic balance to get low vibration, low noise, and high reliability.
5.Applying advanced blower structure design to make an easy installation, operation and maintenance. PLC to realize real time monitoring for the blower running, the vibration and temperature of the bearings, anti-surge control, the start of interlock protection, trouble alarm, lubricating oil pressure, and oil temperature control.
