无底阀水泵是煤炭部1978年至1980年重点推广的节能先进技术之一。水泵是一种通用机械,据有关单位统计,全国各行各业拥有各种水泵300万台。它又是煤炭工业生产矿井四大关键设备之一。全国统配煤矿拥有主排水泵5000多台。水泵是一种高能耗的设备,煤矿生产排水用电约占整个矿井生产用电的27％,这样全国统配煤矿每年用于排水的电量将近30亿度。广东省煤矿是地方煤矿,矿井规模和产量都比较小,全省原煤年产量只有七、八百万吨。但就拥有水泵473台,装机容量59362kW。
Bottomless valve pump is one of the advanced energy-saving technologies promoted by the Ministry of Coal Industry from 1978 to 1980. Pump is a kind of general machinery, according to the relevant statistics, all walks of life in the country has a variety of pumps 3000000. It is also one of the four key equipment for the coal industry to produce mines. National coal mine has the main drainage pump more than 5,000 units. Pump is a high energy consumption equipment, coal mine drainage electricity production accounts for about 27% of the electricity production of the entire mine, so that the country’s coal mines for drainage every year, nearly 3 billion degrees. Coal mines in Guangdong Province are local coal mines with relatively small-scale mines and output. The province’s annual output of raw coal is only about seven or eight million tons. But it has 473 pumps, installed capacity 59362kW.
