Variable frequency constant pressure water supply system

Abstract

The invention relates to a variable frequency constant pressure water supply system. The system comprises a water tank, a pipeline, a water pump unit, an electric operation system and a sensor, wherein the sensor is mounted on the water tank; the water tank is connected with the water pump unit through the pipeline; the water pump unit is controlled through the electric operation system. The variable frequency constant pressure water supply system is scientific and reasonable in structural design, low in equipment investment, easy to maintain and good in energy-saving effect.

Description

Technical field [0001] The invention belongs to the field of water supply systems, in particular to a variable frequency constant pressure water supply system. Background technique [0002] The water supply methods in the prior art mainly include: (1) High-level water tank water supply method: This method is relatively backward, one is that the investment is large, and the other is that it is not conducive to maintenance and earthquake resistance, and the water quality is seriously polluted. (2) Air pressure water supply method: Although the air pressure water supply method is improved compared with the high-level water tank water supply method, there are still many shortcomings, such as large area, high investment in water tank and pump room, frequent start of motors, high power consumption and water supply The water pressure is unstable. (3) Frequency conversion water supply mode: The essence of the frequency conversion water supply system is the frequency conversion speed reg...
