Developing History of Water Hydraulic Technology and its Application in Coal Mine Production
Water hydraulic technology, an ideal green technology, attracts great attention in the field of power transmission & control technology. In this technology, natural water or sea water is used to replace mineral oil as working fluid in hydraulic circuits, with the great advantages of fireproofing, environment protection, safety, and with lower price. The paper introduces the changing process of the working fluid between water and the mineral oil after a brief review of the development of hydraulic technology, summarizes the achievements in the research of water hydraulic technology in China and other countries, analyzes the current technological problems such as friction and wear in components and the vibration noise in hydraulic systems, and it also discusses the application and prospect of the water hydraulic technology in the coal mine production systems, such as hydraulic support, gas drainage, and so on.
