2.3.8. Blade adjustment

叶片调节

The rotor blades are adjusted during operation (pitch control) by an oil hydraulic servomotor which is flan ged

to the impeller and rotates with same. The servomotor mainly con sists of cyli nder, pist on, guide spin dle and

con trol eleme nts.

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 adjusti ng the blades the axial moveme nt of the servomotor pist on is con verted into rotation via the

adjusting levers of the pivoted blade shafts. The blades can thus be adjusted variably. The respective blade an

gle can be see n 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 mini mal. This adjusti ng moveme nt is activated from outside by the con trol

system via rods (assy. actuator). The adjust ing pist on and thus the adjusti ng disc follow each con trol bush

moveme nt. The adjust ing disc tran sfers the adjusti ng pist on moveme nt as rotati on to the blade shafts via

slid ing 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 con trol system such that there is no con sta nt ope ning and clos ing of the blades around a load

point set at the fan. Badly damped con trol systems cause con sta ntly small moveme nts of the blade adjust

ing system, which should be avoided as they affect the service life of the blade beari ngs.

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 con trol oil supplied by the oil supply unit is supplied via the con trol slide at a con sta nt 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 adjust ing device and the oil supply un it form a closed system. When the oil supply is in

terrupted the blade an gle set before the in terruptio n is maintained if the adjust ing pulse is in terlocked by

the con trol oil pressure. The adjust ing 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!

要

The blades may only be actuated whe n a con trol oil pressure has built up.

仅当控制油压已经建立后，才能开

启叶片。

grooved ball-beari ng race to absorb the adjustme nt force. These bearings are permanently lubricated with oil

and sealed with O-rings.

叶片轴承的轴向推力球轴承可承受叶片离心力，径向球轴承可承受叶片调节力，叶片轴承注油后可持久润滑，由
