温控阀是风电齿轮箱润滑系统中一个重要部件,由于风电齿轮箱载荷很大,转速很高,运行过程中发热严重,润滑和冷却就显得尤为重要,而温控阀就是控制整个润滑冷却系统内油温的关键部件。

在风电齿轮箱润滑冷却系统中润滑油经过滤器过滤后到达温控阀,温控阀可以根据润滑油油温来控制润滑油的流向,一般当油温低于45℃时,润滑油无需经过冷却,直接进入齿轮箱油路分配块,而当油温高于45℃时,温控阀开始工作,润滑油将先进入冷却器(常见风冷或水冷),经由冷却器冷却后,润滑油回到齿轮箱油路分配块。

温控阀工作时,工作原理如下:

⑴ 依靠密封在活塞内的空气,受热膨胀推动活塞的反作用力,以及弹簧的弹力,共同作用于阀体,使之移动,达到切换油路的目的。

⑵ 当油温过高,密封的空气受热膨胀时,推动活塞上移,由于活塞顶在温控阀盖上无法移动,迫使阀体在活塞的反作用力下,克服弹簧的阻力,推动阀体下移,从而断开直通油路,接通油冷却通道,高温润滑油进入散热器进行冷却后,再进入齿轮箱。

⑶ 当油温降低,密封的空气收缩,弹簧的弹力逐渐大于活塞的作用力时,弹簧推动阀体上移,从而断开冷却油路,接通直通油路,润滑油直接进入齿轮箱。

⑷温控阀在油温达到45℃开启,50℃时全开,在此切换过程中,油将同时在直通齿轮箱的管路和通往散热器的管路中过流,并随着切换过程2路流量大小有变化,但总流量不变。

温控阀直接决定润滑油是否得到冷却,当风机频繁出现油温过高时,不妨检查一下温控阀是否正常工作吧!
