=====================================

The circulating water pump of the closed circulating water system adopts the advanced frequency conversion control technology, which is an effective measure to change the low-efficiency operation and energy-saving of the pump. The circulating water system is in the state of non-constant current and constant pressure during its operation. The change of the flow rate and head of the circulating water system is controlled by adjusting the outlet valve of the pump, it changes the characteristic curve of the water delivery system and causes unnecessary waste. The regulating valve causes the motor power to waste the regulating valve, the pipeline system flow meets the requirements, then the pump operating efficiency is improved, but it causes the head loss on the valve, and the power provided by the motor is consumed on the valve without useful work. Flow regulation results in wasted energy flow reduction without any operation, pump efficiency is improved, there is no head loss on the valve, but the static head is improved, raising the head unnecessarily is also a waste of energy. The circulating water pump uses the frequency conversion control technology, causes the system to be in the constant pressure condition, at this time the valve on the pump completely opens, does not make the control, the system demand flow change, is through the system to return the pressure control signal, pump motor by adjusting the speed to ensure that the system pressure of a constant value to achieve flow regulation. At this time the circulating water pump is in the most economical running condition.
