“ 水泵 组 + 变频电控柜 ” 的形式。 The water supply equipment has a variety of structures and control methods. The structure of the water supply equipment mostly adopts the form of " water pump unit + variable frequency electric control cabinet " . “ 多用水、多耗电；少用水、少耗电 ” 的节能特点。 Therefore, domestic water supply equipment should have the energy-saving characteristics of " more water and more power consumption; less water and less power consumption " . The air pressure tank is a prerequisite for the water pump to go to sleep. Utilizing the extremely low compressibility of water, the water is stored in the tank with external force, and the gas is compressed by the compression pressure. When the external force disappears, the compressed gas expands to remove the water. Since the compression ratio of water is much smaller than that of gas, when the pipe network has a small flow leakage, it can cause a large drop in pressure, which can cause the pump to start frequently. If the power frequency pump supplies water directly to the user, it must be equipped with a pneumatic tank to ease the frequent start of the pump.
