自贡市农机技术人员,针对农用水泵耗能多、成本高等问题,作了一些技术改造,收到了很好的节能效果。 1.改进管道装置在水泵进、出口水管上各安装一个90°弯头,并将水泵斜装,使出水口正对出水池。尽量缩短管道长度,减少弯头数量;调整水泵安装高度,消灭“高射炮”式的出水管口等。 2.去掉多余的叶轮去掉叶轮的数目,由水泵额定扬程除以每个叶轮承担的扬程而定。 3.离心泵去底阀离心泵去掉底阀后,可在出水管口装拍门,利用柴油机的吸气把管路中的空气排出,实现真空抽水;还可在柴油机排气管上装引射器,把水泵进气管中的空气引出来。 4.换口环,调整轴向间隙离心泵长期使用后,叶轮口环间隙增大,容积效率下降。因此,在使用过程中,要定期检查口环间隙。对磨损的口环,要
Agricultural machinery and technical personnel in Zigong City, for agricultural pump energy consumption and high cost, made some technical transformation, received a very good energy-saving effect. 1. Improve the pipeline installation in the water inlet and outlet pipes to install a 90 ° elbow, and the water pump ramp loading, so that the outlet is right out of the pool. Try to shorten the pipe length and reduce the number of elbows. Adjust the installation height of the water pump and eliminate the “anti-aircraft” water outlet. 2. Remove the excess of the impeller to remove the number of impeller, the pump rated head divided by the impeller shoulders each bear. 3. Centrifugal pump to the end of the valve centrifugal pump to remove the end of the valve, the valve can be installed in the outlet port, the use of diesel suction pipe to the air discharge, to achieve vacuum pumping; Device, the pump inlet air leads to. 4. Change the ring, adjust the axial gap Centrifugal pump long-term use, the impeller mouth ring gap increases, the volume efficiency decreases. Therefore, during use, to regularly check the mouth ring gap. To the worn mouth ring, want
