Constant pressure control for water supply in high-rise buildings, domestic water, fire fighting water, and closed-loop industrial process water.
Automatic control of boiler feed pumps and thermal heating circulation pumps.
Farmland irrigation and fountain control.
Air conditioning system and cooling circulating water control.
Secondary pressure control for flow systems in water plants, pump stations and petrochemical industry.
TSLB frequency conversion cabinets can be used as motor control cabinets for various production lines requiring energy-saving renovation or zero-speed starting.
High efficiency and energy saving.According to motor theory, the power consumption of a motor is in cubic relation to its rotational speed. Under constant pressure, the water output of a pump is proportional to the motor speed.
This equipment operates on a constant pressure and flow mode. When water demand decreases, the system maintains constant pipe network pressure and reduces water supply by lowering pump speed, resulting in cubic reduction of power consumption.
For example, when water supply is 80% of the rated value, motor energy consumption is 51.2% (0.8³) of the rated value, saving 48.8% energy. Although the actual energy-saving rate of the system is slightly lower than the theoretical value, it is still considerable.
