山东省引黄济青工程王耨泵站设有6台1.6HL—50A型导叶式混流泵和与之配套的TL800—24/2150型同步电机,另外装设2台900HLB—10立式混流泵和JSL—15—10型立式异步电动机,供调节流量之用。该站自1989年10月试运行至今已10年,通过这10年的运行统计,室温在15～17℃时,各机组瓦温温升变化较大,其中1~#机组推力瓦温升为51℃,3~#机组上导、推力瓦温升为40.5℃,4~#推力瓦温升为40℃,6~#机组上导瓦温升为39℃。瓦温偏高的原因及处理方法如下:
Shandong Huangdu Jiqingzheng Wang pumping station has six sets of 1.6HL-50A guide vane type mixed flow pump and its accompanying TL800-24 / 2150-type synchronous motor, the other with 2 sets of 900HLB-10 vertical mixed flow pump and JSL-15-10-type vertical induction motor, for regulating the flow of use. The station has been in operation for 10 years since its trial operation in October 1989. According to the operation statistics of the past 10 years, the temperature rise of tile varies greatly at room temperature of 15-17 ° C, among which the temperature rise of 1 ~ 51 ℃, 3 ~ # unit on the guide, thrust tile temperature rise to 40.5 ℃, 4 ~ # thrust tile temperature rise to 40 ℃, 6 ~ # unit guide temperature rise to 39 ℃. The reason for the high temperature and the method of treatment are as follows:
