三、进口工作(快速)门工作门孔口净面积6.5×10平米,设计工作水头(后期)60米,口门进流平均流速约为 4.2米/秒.闸门采用胶木支承,单位压力取3吨/厘米在此压力下(摩擦系数最小)。曾经考虑采用定轮支承方案,但一方面由于门槽需要的空腔很大,水力学条件会由此变坏;另一方面由于轮压高,轮径大,需用铸钢量大(定轮和轨道),相应的制造安装工艺要求也较高,经济上不合算.而且根据上述设计参数计算和布置,轮子布置不下(进口闸门总水压力达3650吨之巨,按每个轮子
Third, the import work (fast) Doors of the door The net opening area of 6.5 × 10 square meters, design work head (late) 60 meters, the average inlet flow rate of about 4.2 m / s gate with bakelite support, the unit pressure to take 3 Ton / cm at this pressure (friction coefficient minimum). Have considered the use of fixed-wheel bearing program, but on the one hand due to the door cavity needs a large cavity, hydraulic conditions will be worse; on the other hand due to high wheel pressure, wheel diameter, the need to use a large amount of steel Wheel and rail), the corresponding manufacturing and installation requirements are also higher, economically not cost-effective .According to the above design parameters and layout, wheel layout (under the gate pressure of 3650 tons of water, according to each wheel
