全国统配煤矿每年用电量,其中排水设备用电占27.2％,涌水量特大的矿井如焦作、涟邵,排水设备用电高达全局生产用电的65—70％。然而,目前大约有60％的排水设备运行效率低,浪费大量的电力,已引起有关部门的重视。为了提高排水设备的经济性,节约能量,煤炭部曾于78年提出推广“无底阀水泵”新技术,83年10月底又在兖州召开了“水泵经济运行座谈会”。不少局矿成立了节电办公室,制定了提高排水设备效率的规章制度。根据调查,综合各矿局的经验,有以下几
The national coal mine annual electricity consumption, of which 27.2% drain electricity equipment, large influx of mines such as Jiaozuo, Lian Shao, drainage equipment, electricity up to the global production of electricity 65-70%. However, at present, about 60% of drainage facilities are inefficient and wasting a lot of electricity, which has drawn the attention of relevant departments. In order to improve the economy of drainage equipment and save energy, the coal ministry proposed to promote the new technology of “bottomless valve pump” in 1978 and convened a “forum on economic operation of water pump” at the end of October, 83 in Yanzhou. Many Bureau mines set up a power-saving office, developed to improve the efficiency of drainage rules and regulations. According to the survey, taking into account the experience of various mines, there are the following
