Drainage and irrigation machinery use and maintenance

With the continuous development of rural economy, advanced irrigation and drainage machinery has been widely used. However, due to the general lack of basic knowledge about users of irrigation and drainage machinery, there are often problems such as inaccurate selection, low efficiency, and difficulty in troubleshooting. In order to improve the technical level of users of irrigation and drainage machinery and efficiently use machinery, we have combined the production practices and extensively consulted literature on drainage and irrigation machinery to compile a book entitled “Usage and Maintenance of Drainage and Irrigation Machinery”. This book explains the profound things in a simple and easy-to-understand way and introduces the structure, performance, installation, maintenance and common fault elimination methods of centrifugal pumps, long shaft deep well pumps, and submersible pumps that are commonly used in rural areas. At the same time, taking into account the serious lack of water resources in China, water-saving irrigation has become the development trend of agricultural irrigation, we have introduced the contents of sprinkler irrigation, micro-irrigation and underground irrigation.
