【摘要】：煤矿主排水泵站为标准设计配置,即多台套大型多级离心泵机组与之相适应的管系、电器装置等。这种"标配"是矿山耗能大户,占总耗能约40%左右,系统节能势在必行。然而,"系统"是"标配"的,无法改变,笔者在与研发高效泵机组同步,对"系统"附加动态能效监测和节能调控装置,经安徽省质监局的现场检测表明,单泵机组系统节能提高15%,吨水百米电耗下降至0.39k W·h。试验结果表明:高效泵机组增效空间有限,但将其用于现有系统,并对其实现动态能效监测和流量调控,就能得到大幅度的节能效果。在此基础上对系统实现对比和优化运行(即考虑多泵运行、多工况运行等)软件模拟运行预测,指导泵站运行,泵站系统节能就有更大空间。
[Abstract]:The main drainage pump station of coal mine is a standard design configuration, that is, many sets of large multistage centrifugal pump units are suitable for the pipe system, electrical equipment and so on.This "standard allocation" is a large energy consumption in mines, accounting for about 40% of the total energy consumption, so it is imperative for the system to save energy.However, the "system" is "standard" and can not be changed. The author is synchronizing with the research and development of high-efficiency pump unit, adding dynamic energy efficiency monitoring and energy saving control device to the "system", and the on-site inspection of Anhui quality Supervision Bureau shows that,The energy saving of single pump unit system is increased by 15%, and the power consumption of 100 meters per ton water is reduced to 0.39 kW / h.The experimental results show that the efficiency space of the high efficiency pump unit is limited, but if it is used in the existing system, and the dynamic energy efficiency monitoring and flow regulation can be realized, the energy saving effect can be obtained by a large margin.On this basis, the system is compared and optimized (that is, considering multi-pump operation, multi-condition operation, etc.) the software simulates the operation prediction, guiding the pumping station operation, there is more room for energy saving in the pumping station system.
