我县是一个丘陵山区,除一些小山塘。小坝、小水库的水利设施外,为了保证农田灌溉,小型内燃提水机占有一定的比重,据1983年统计数,已有小型排灌动力656台,计8450马力。根据我们的经验:平皮带轮的中心距应该适当简易计算,是否以皮带盘直径的和再乘以5为宜,再按此计算皮带长度。如柴油机或汽油机的转速是1500转/分,但必须选用皮带盘使水泵转速为1400转/分至1450转/分,不得超过1500转/分。这是因为皮带传动中,皮带有一个打滑系数值,一定要考虑一个打滑系数进去。
My county is a hilly mountain area, except for some small ponds. Small dams, small reservoirs of water conservancy facilities, in order to ensure farmland irrigation, small internal combustion water purifier occupies a certain proportion, according to 1983 statistics, there are 656 small-scale irrigation and drainage power, total 8450 horsepower. According to our experience, the center distance of the flat pulley should be properly and simply calculated. Whether the sum of the diameter of the belt pulley is multiplied by 5 is more appropriate. Then calculate the belt length. Such as the diesel engine or gasoline engine speed is 1500 rev / min, but must choose the pulley so that the pump speed of 1400 rev / min to 1450 rev / min, shall not exceed 1500 rev / min. This is because the belt drive, the belt has a value of slip factor, we must consider a slip factor into it.
