在群众性的大搞水力站的运动中,有些地方因缺少水轮机的钢轴和推力轴承等,便停下来等待设备。没有钢轴和推力轴能不能建造水力站呢?浙江省嵊县的实践经验证明是完全可能的。他们全部用木头建造了几十座水力站,运转正常,效果良好。现将这种水力站的构造分别介绍如下。(1)木主轴木料选用檀木、樟木或其他硬木。水头小于6米,出力在50马力以下的水轮机都可采用木轴。水头小于4米者可用木轴顶车。计算木轴直径时,用公式d=(30—40)~3(N/n)~(1/2)(厘米)式中:N 为水轮机出力(马力),n 为水轮机转速(转/分)。木质坚硬良好的木头,计算时前面的系数可用较小的值。
In the mass mobilization of hydropower stations, some places stopped waiting for equipment due to the lack of steel turbines and thrust bearings. No steel shaft and thrust shaft can build hydraulic station it? Zhejiang Sheng County proven experience is entirely possible. All of them built up dozens of hydraulic stations with wood, and they worked well and worked well. Now the structure of this hydraulic station are described below. (1) wood spindle wood selection of sandalwood, camphor or other hardwood. Water head less than 6 meters, the output of 50 horsepower below the turbine can be used wooden shaft. Less than 4 meters head can be used wooden top car. Calculate the diameter of the wood shaft, using the formula d = (30-40) ~ 3 (N / n) ~ (1/2) (cm) Where: N is the turbine output (horsepower), n is the turbine speed ). Good hard wood wood, the calculation of the front coefficient can be used for smaller values.
