Energy-saving no-negative-pressure direct-connected water supply equipment
The invention discloses energy-saving no-negative-pressure direct-connected water supply equipment. The energy-saving no-negative-pressure direct-connected water supply equipment mainly comprises a steady-flow compensator, a no-negative-pressure controller, a low-flow pump, main pumps, a flow detection device, a surge tank and a control cabinet. During normal operation, the main pumps supply water through frequency conversion and speed regulation; at the low flow of water using low cycle, when the flow detection device detects that the flow rate is lower than the set low flow rate value and the condition lasts for 5-30 s, the main pumps are stopped, and automatic switching to the low-flow pump is realized for variable-frequency water supply; and after the low flow passes, when frequency conversion of the low-flow pump cannot meet the water supply demand for increased water consumption, automatic switching to the main pumps is realized for the variable-frequency and speed-regulating water supply state, and the low-flow pump stops. The energy-saving no-negative-pressure direct-connected water supply equipment has the benefits that the advantages of compact structure, small occupied area, convenient installation and maintenance, energy-saving operation, sanitary water supply and the like are achieved, the degree of automation is high, the protection functions are complete, and the energy-saving no-negative-pressure direct-connected water supply equipment has a very good development prospect and economical effects when applied to secondary water supply in residence, offices, hotels and the like.
