The invention provides an automatic dormancy control system of a one-frequency one-pump constant-pressure secondary water supply device, and aims to solve the problems in the prior art that in the dormancy control technology of the one-frequency one-pump constant-pressure secondary water supply device, water supply pressure of the municipal water supply network is not considered and the power consumption is increased. According to the invention, a water inlet pressure sensor is arranged at the connection part of the municipal water supply network and the constant-pressure secondary water supply device, a detection value is delivered to a control unit, and the control unit automatically regulates the dormancy frequency value of the constant-pressure secondary water supply device; when the water pressure value of the municipal water supply network is lowered, the dormancy frequency value of the constant-pressure secondary water supply device is increased, and when the water pressure value of the municipal water supply network is increased, the dormancy frequency value of the constant-pressure secondary water supply device is lowered. The system has the beneficial technical effects that when the pressure of the municipal water supply network changes, the dormancy frequency value is regulated automatically to enable a water pump to start or stop reasonably to lower power consumption.
Description
[0001] field of invention [0002] The invention relates to dormancy control technology for urban constant-pressure secondary water supply equipment, in particular to an automatic dormancy control system for one-frequency-one-pump constant-pressure secondary water supply equipment. Background technique [0003] In order to ensure that the water supply of urban high-rise buildings has a pressure that meets the requirements of use, a secondary water supply system is usually used to ensure that users on different floors have approximately the same tap water pressure. The so-called secondary water supply means that after the municipal water supply pipe network is connected to the high-rise building, a secondary water supply storage tank is set on the roof, and the municipal water supply is raised to the roof storage tank through a water pump, and then connected to users on different floors through the pipe network; Or use the water pump to pressurize, and then connect to users o...
