Non-negative pressure frequency conversion water supply facility

Abstract

The invention discloses a non-negative pressure variable-frequency water supply device, comprising an electric frequency control cabinet, a water lifting device, a decompressor, a pressure detection device and water amount control valves. The water lifting device is composed of a submersible pump and a tank body; the submersible pump is arranged inside the tank body; both the water inlet of the tank body and the water outlet of the submersible pump are provided with water amount control valves; the water inlet of the tank body is connected with a water supply pipe network; the water outlet ofthe submersible pump is connected with a secondary pressure water supply pipe network; the pressure detection device is arranged on the tank body, and the decompressor is arranged on the water supplypipe network which is connected with the water outlet of the submersible pump; and the power output source of the electric frequency control cabinet is connected with the lifting device. Adopting a surge-less deep well submersible pump, the non-negative pressure variable-frequency water supply device can save 40-70%of electricity. Meanwhile, the non-negative pressure variable-frequency water supply device is connected with municipal water supply pipe network and unable to generate negative pressure, with water seal, water lubrication, no noise, no leakage and maintenance free, thus saving cost.

Description

technical field [0001] The invention belongs to the field of water supply for high-rise buildings, and specifically refers to a secondary pressurized water supply device applicable to high-rise buildings. Background technique [0002] The frequency conversion speed regulation technology has been applied to the secondary pressurized water supply system of high-rise buildings. It has a history of nearly 20 years, and it has entered a popular stage. (control circuit) automatic control program programming, frequency conversion speed regulation processing and application) water supply and drainage design complete set of equipment selection and design in one combination of multiple professional technologies. Due to the lack of technical communication and cooperation among industries, disciplines, and professions, there are technical blind spots among industries, disciplines, and professions. After nearly ten years of development, tens of thousands of complete sets of equipment ha...
