2. Descriptions简介
2.1. Fluidic effect (1-stage)工作原理（单级）
On entering the direction of the flow is altered in the suction bend, accelerated by a nozzle and directed into the impeller.
气流由系统管道流入风机进气箱后改变方向，经集流器收敛加速后流向叶轮。
In the impeller the axially-directed flow becomes circumferential and is accelerated. The pitch angle of the rotor blades is infinitely variable during operation. The adjustment has the effect of changing the volume flow.
电动机带动叶轮对气流作功，动叶的工作角度与叶栅距可无级调节，由此改变风量、风压满足工况变化需求。
After the impeller the guide vanes (outlet guide-vane unit) redirect the flow in an axial direction, thus increasing the pressure (reaction-type fan).
气流由轴向运动经叶轮作功后变为螺旋运动，流出的气流经后导叶导向转为轴向流动。
In the diffusor the kinetic energy is then converted into static pressure. 再经扩压器，将部分动能转换成静压能，流至系统满足运行要求。

The rotor blades are adjusted during operation (pitch control) by an oil hydraulic servomotor which is flanged to the impeller and rotates with same. The servomotor mainly consists of cylinder, piston, guide spindle and control elements.
动叶片在运行中可通过液压伺服马达来控制调节（节距控制）。伺服马达通过法兰连接在叶轮上，跟随叶轮同步转动。伺服马达主要包括缸体、活塞、导轴及控制阀。
When adjusting the blades the axial movement of the servomotor piston is converted into rotation via the adjusting levers of the pivoted blade shafts. The blades can thus be adjusted variably. The respective blade angle can be seen locally on the graduated plate.
调节叶片角度时，伺服马达活塞的轴向运动通过曲柄带动叶片轴转动，变成旋转运动。叶片由此调节角度。叶片角度可以通过表盘读出。
To initiate the blade movement the control bush which does not rotate with the impeller is moved axially. The force required therefore is minimal. This adjusting movement is activated from outside by the control system via rods (assy. actuator). The adjusting piston and thus the adjusting disc follow each control bush movement. The adjusting disc transfers the adjusting piston movement as rotation to the blade shafts via sliding blocks and levers.
叶片动作时，未跟随叶轮转动的控制阀套作轴向移动。因此只需要较小的力量。调节移动时通过外部的执行装置（电动执行器）来操作的。控制阀套移动时活塞和调节盘跟随移动。调节盘将活塞的移动通过滑块和曲柄转换成叶片轴的旋转运动。
Adjust the control system such that there is no constant opening and closing of the blades around a load point set at the fan. Badly damped control systems cause constantly small movements of the blade adjusting system, which should be avoided as they affect the service life of the blade bearings.
由于风机运行过程中各个工况点所需的叶片开度各不相同，所以需要调节叶片角度。应避免严重阻尼的控制系统引起叶片调节系统持续的小运动，防止由此造成的轴承寿命降低。
The control oil supplied by the oil supply unit is supplied via the control slide at a constant pressure. The pressures to be set are specified by CKPF.
油站提供恒定压力的控制油，通过控制阀的滑动来实现。油压由CKPF确定。
This hydraulic adjusting device and the oil supply unit form a closed system. When the oil supply is interrupted the blade angle set before the interruption is maintained if the adjusting pulse is interlocked by the control oil pressure. The adjusting system will not be damaged.
液压调节装置和供油系统为封闭回路系统。当供油受阻时，控制油压使得控制信号互锁，叶片角度设置将维持受阻前状态。
IMPORTANT!重要
The blades may only be actuated when a control oil pressure has built up. 仅当控制油压已经建立后，才能开启叶片。
