Intelligent constant-pressure variable-frequency water supply system and application method

Abstract

The invention relates to an intelligent constant-pressure variable-frequency water supply system. The system comprises a constant-pressure secondary water supply system body, a water tank, an air pump, a stabilized voltage supply and a storage battery A, the system is further provided with pressure acquisition and control equipment, a first control circuit and a second control circuit, the pressure acquisition and control equipment comprises a pressure switch, a storage battery, an electromagnetic valve, a trigger sub-circuit and a switching power supply which are mounted together and electrically connected, the water tank is divided into two independent parts, and the air pump, an electromagnetic valve A, an electromagnetic valve B, an electromagnetic valve C, a pressure switch A, a liquid level switch, a one-way air valve, an electromagnetic valve D, a liquid level switch A and an electromagnetic valve E are installed on the water tank and electrically connected with the storage battery, the trigger sub-circuit, the switching power supply and a booster pump which are installed in an element box. An application method of the intelligent constant-pressure variable-frequency water supply system comprises four steps. According to the system, the requirement for overhigh water pressure of the booster pump can be reduced, energy consumption of the booster pump is reduced, water consumption after power failure can be guaranteed, the cost is low, field space is not occupied, and intelligentization is achieved.

Description

Technical field [0001] The present invention relates to a secondary water supply equipment and technological application methods, in particular, an intelligent frequency constant water supply system and application methods. Background technique [0002] Secondary water supply system for the high frequency constant architectural applications, a more widely used secondary water supply devices, under voltage will work municipal network water flows into the storage tank, and constant pressure control system through the relevant secondary water supply devices the pressure booster pump water out from the tank, sent to the user pipeline for household use high-rise buildings. Operation, the control board will collect real constant frequency of the secondary water supply system and all user-side communicating pipe pressure pressure switch signal (several residential buildings in the booster pump inlet ends and separate outlet ends through a total the pipe are connected in parallel, a sepa...

Problems solved by technology

[0004] In order to overcome the structural limitation of the existing constant pressure secondary water supply system, the control circuit board collects the signal of the pressure switch installed on the side of a single main water outlet pipe of the booster pump, and cannot collect the water of each building in the residential area separately. Pressure data and control, due to the different floor heights of the residential area, the booster pump will uniformly increase the water pressure and water volume for each building when it is working, which will cause unnecessary waste of electric energy, and will cause users to be unable to use water for a period of time after a power outage Disadvantages, the present invention provides a body based on the constant pressure secondary water supply system, each building in the residential area is equipped with pressure acquisition and control equipment, and the pressure acquisition and control equipment of each building can set the water pressure and water volume according to its own floor , control and the solenoid valve connected in parallel with the total outlet of the booster pump to open or close, under the premise of meeting the water demand of its own floor, it also reduces the water pressure demand for the booster pump as much as possible (especially the advantages of low floors are more obvious), and the corresponding reduction The energy consumption of the booster pump is reduced, and it can also automatically supply water to the households through the water distribution tank when the power is cut off. Space in the water supply area (installed at the water tank, the installation space used is extremely small), and an intelligent constant pressure variable frequency water supply system and application method that achieves the purpose of lower cost
