But in Heilongjiang province, one of the important accomodity grain bases in our country, some problems of electical irrigation and drainage station need to solve as soon as possible. The paper analyzed the problems existed in electrical irrigation and drainage pumping station and reasons of the problems for a long period in Heilongjiang province. We have put a in depth research into practice for the two typical pumping stations among them. According to their material situation, proposed relevant reforming measures and performed the estimate on their economic benefit. It is certain to provide referable experience and a good sample for the energy saving and technology reforming of some middle and small scale electrical irrigation and drainage pumping stations.
