设计一台新型水轮机都必须进行导水机构接力器油压计算,并作出曲线。过去每个水头下选择10个开口值,共选3个水头,则计算需4～6天。现用DJS-7电子计算机计算,每个水头选20个开口值,选用6个水头,仅需10分钟。不仅计算速度快,而且提高了计算精度。现将计算介绍如下。一、基本数据DO——导叶布置圆直径(米)BO——导叶高度(米)ZU——导叶数DC——控制环连杆销布置圆直径(厘米)DY——控制环耳柄销布置圆直径(厘米)LH——导叶臂长(米)DA、DB、DD——导叶下、中、上轴颈直径(米)NO——导叶相对偏心比B——导叶全关时接触宽度(厘米)
The design of a new type of turbine must be carried out hydraulics relay hydraulic calculations, and make a curve. In the past, under the head of each choice of 10 openings, a total of three head, the calculation will take 4 to 6 days. DJS-7 computer is now used to calculate the computer, each head election 20 openings, the choice of 6 head, only 10 minutes. Not only calculating speed, but also improve the calculation accuracy. The calculation is introduced below. First, the basic data DO - guide vane layout circle diameter (m) BO - vane height (m) ZU - vane number DC - control link rod pin diameter (cm) DY - control ring ear Diameter of handle pin (cm) LH - Length of guide vane arm (m) DA, DB, DD - Diameter of lower, middle and upper journal of guide vane (m) NO - Relative eccentricity ratio of guide vane B - Guide When the leaf is fully closed contact width (cm)
