1,Inlet guide vane device
Compsed of nine vanes, the inlet guide vane device is installed before impeller and its open degree is controlled by an electric operator. When the electric operator receives 4-20mA signal from control panel, it adjusts the vanes' open degree(the value of open degree is both shown on the panel of electric operator and on the control screen) so that the inlet guide vane device can work before gas flows into the impeller aand realize the function of airflow adjustment of 45-100%.

2,Volute
The most suitable volute runner is adopted for reliable pneumatic performance, high efficiency and for achieving all the multivariate efficiency to 85%.

3,Step-up box
Helical type step-up gear is equipped.The gare is diffusion hardened and of excellent performance under high-speed rotation and long service life.

Bearing of sliding type with Babbitt metal surface is adopted.The bearing takes lubricant film for supporting its shaft and cooling.It is featured with low friction,high antiknock characteristic,reliable performance and longevity.



4,High efficiency impeller
The impeller, which is ternary mixed semi-open type, is designed by the three-dimensional theory . The curve for the impeller is selected recurring to simulate

working condition on computer, and better fitting for the actual flowage of gas. Meanwhile, it reduces the vane deformation caused by centrifugal force and improves the efficiency reliability.
The advances connection type is adopted for the impeller and high-speed shaft.Before delivery ,impeller over-speed and dynamic balance tests are taken for ensuring the high performance of blower.
The material of the impeller is optional, aero-metal or stainless steel or other materials available according to the custom's requests.

Blower structure

Gs series centrifugal blower features single-stage cantilever,axial inlet and radical discharge structure. Air comes into the suction pipe and the

inlet guide vane device from the inlet filter setting.Main driving motor is connected with the coupling and the step-up box.When start,
the step-up gear drive the ternary mixed semi-open impeller to make gas for power,and the gas discharge out through vane-less diffuser and

volute chamber.

High grade automation,and reliable

Using self-turing intelligent instrument or programmable logic control (PLC) and man-machine conversation interface for the whole runing process, which can realize adjusting airflow automatic/ manual.GS series blower control system includes: blower,step-up box,motor,lubricant station,inlet

filter,air relief adjustable valve,shaft vibration ,anti-surge system,etc.It takes didital display touch screen control panel,and can process the full control and regulation through the corresponding software.Meanwhile, it can record various failures and dagnose the failures intelligently as well as

suggesting the cause of failures.

The pivotal components for the automatic control system are imported ones for ensuring the accuracy, reliability and easy maintenance of the control system.

Remote monitor

Control system can transmit the measured data through internet or GPRS emitter. Customers can login in our website(Http://www.bk.com.cn) to monitor the running condition; meanwhile, our company will monitor it periodically and send the important monitor point or abnormal information to

customers via short message or mail. This remote monitor system is a further guarantee for the safe running of blower.
