【摘要】：对南水北调东线一期工程中不同结构型式的灯泡贯流泵,按照工况调节方式和传动方式及总体结构的组合,归纳为变频调节整体紧凑结构型(I型)、变频调节现场可拆装结构型(II型)、齿轮箱传动机械全调节现场可拆装结构型(III型)和液压全调节现场可拆装结构型(IV型)等4种结构型式.根据机械和液压式叶片全调节以及变频变速调节等工况调节方式,以及直接传动和通过减速齿轮箱的间接传动的不同传动方式,对4种不同结构型式的主要特点进行了定性和定量分析.研究结果表明:不同结构的灯泡贯流泵均安全、可靠,其中IV型结构机组在最大水推力及反向推力等不利工况下,最大变形值约为0.2 mm,不同部位的变形差小于0.1 mm,但在结构特性方面有明显差异.IV型机组的重量达225 t,约为I型结构的3倍;与叶片调节相比,采用变频变速调节时,不仅能够简化机组的结构,而且水泵可以采用柱形轮毂,提高效率1.6%以上.
[Abstract]:According to the combination of working mode, transmission mode and overall structure, the bulb tubular pump with different structure in the first phase project of South-to-North Water transfer Project is summed up as the integral compact structure type of frequency conversion regulation. Frequency conversion regulation field detachable structure type II). Gear box transmission machinery fully regulated field detachable structure type III) and hydraulic fully regulated field detachable structure type IV). According to mechanical and hydraulic vane full regulation and variable speed variable frequency adjustment and other working conditions. And different transmission modes of direct transmission and indirect transmission through deceleration gearbox. The main characteristics of four different structure types are analyzed qualitatively and quantitatively. The results show that the bulb tubular pumps with different structures are safe and reliable. The maximum deformation value of type IV unit is about 0.2 mm under unfavorable working conditions such as maximum water thrust and reverse thrust, and the deformation difference of different parts is less than 0.1 mm. However, there are obvious differences in structural characteristics. The weight of type IV unit is 225 t, which is about 3 times of that of type I structure. Compared with vane regulation, the variable frequency variable speed regulation can not only simplify the structure of the unit, but also use the cylindrical wheel hub to increase the efficiency of the pump by more than 1.6%.
