摘　　要：针对某采区供水系统末端负荷用水量不能确定的问题,提出了一种多台水泵自动恒压供水系统的设计方案。该系统采用PLC及变频器控制水泵,确保在末端负荷变化大时,自动调节水泵功率和数量,从而实现恒压供水。实际应用结果表明,该系统既保证了设备冷却水系统及防尘水系统所需要的水压,又避免了水压大幅波动问题,降低了采掘工作面设备故障率。In view of problem that terminal water consumption of water supply system in a mining area cannot be determined, a design scheme of automatic constant-pressure water supply system was put forward. The system uses PLC and frequency converter to control water pump to ensure that the pump power and quantity can be automatically adjusted when terminal loads change greatly, so as to achieve constant pressure water supply. The practical application result shows that the system not only ensures the water pressure required by equipment cooling water system and dustproof water system, but also avoids sharp fluctuation of water pressure and reduces failure rate of equipments on working face.
