一、10年迈大步,“九五”期间又上新台阶 “七五”以来,国有重点煤矿响应国家号召,开展以风机水泵为重点的节电工作,装备水平不断提高,到1996年底节电29.1亿kW·h。 1982年,煤炭部系统在全面开展煤矿机电质量标准化、安全创水平、建设现代化矿井和企业升级活动中,制定了以风机水泵为重点的节电标准,普遍进行了大型设备的技术测定和电平衡测试;研制高效耐磨矿用水泵以及与之配套的机电一体化电机;普及推广了矿井主排水泵射流无底阀排水和水力清管技术,清理立井、斜井主排水管路。在推广应用高效节能风机的同时,将老旧杂风机的直风叶改为扭曲风叶;减小轴、径向间隙;匹配与风叶
First, 10 years of striding, and during the “Ninth Five-Year Plan” period in the “Ninth Five-Year Plan” period, key state-owned coal mines responded to the call of the country to carry out energy-saving work focused on fans and pumps. The level of equipment has been continuously improved, and electricity has been saved by the end of 1996. 291 million kW·h. In 1982, in the comprehensive development of coal mine electromechanical quality standardization, safety level creation, modernization of mines, and enterprise upgrade activities, the Ministry of Coal has formulated energy-saving standards focusing on fans and pumps, and has generally conducted technical measurement and electric balance of large-scale equipment. Test; development of high-efficiency and wear-resistant mineral water pumps and their associated electromechanical integrated motors; widespread promotion of mine main drainage pump jet bottomless valve drainage and hydraulic pigging technology, cleaning vertical shaft, inclined well main drainage line. While popularizing and applying energy-efficient fans, the straight blades of the old ones will be replaced with twisted blades; the shaft and radial clearance will be reduced;
