Description
Technical field
The present invention relates to secondary water-supply technical field, specifically a kind of variable quantity and pressure changeable water supply controller.
Background technology
At present, secondary water-supply generally adopts frequency conversion and unvarying pressure control, is characterized in water outlet constant voltage, pressure adjustable, is conducive to pump selection and automatically controls, and energy-conservation.But frequency-changing pressure stabilizing can not adapt to the pressure change that resistance of pipe system reduces with water consumption well, there is unnecessary, invalid lift waste, can not be energy-conservation to greatest extent.It is according to " flow-resistance of pipe system family curve " adaptively modifying discharge pressure that secondary water-supply variable quantity and pressure controls, make a kind of control mode that discharge pressure changes with water consumption change, thus eliminate the unnecessary lift waste that constant pressure water supply reduces at flow, reach maximum energy-saving effect.But current secondary water-supply variable quantity and pressure controls to be mostly PLC and controls, and without nonshared control unit, and adopts PLC often to need to carry out secondary expansion, by causing, installing space is large, cost is high and use inconvenient defect for this.
Summary of the invention
The object of the present invention is to provide the variable quantity and pressure changeable water supply controller that a kind of strong adaptability, cost are low, volume is little and easy to install.
The technical solution adopted for the present invention to solve the technical problems is: a kind of variable quantity and pressure changeable water supply controller comprises CPU module, and the analogue collection module to be connected respectively with CPU module, switching value acquisition module, analog output module, switching value output module and fault output module, also comprise remote pressure acquisition module and monitoring module, described CPU module is connected with described remote pressure acquisition module and monitoring module respectively, described remote pressure acquisition module and monitoring module are connected with the pipe network terminal pressure pick-up unit of outer setting and communication network more respectively, described CPU module is also provided with power interface and communication interface, and be connected to display and printer, described analogue collection module and switching value acquisition module are installed in the pressure transducer of secondary water-supply facility respectively, flow sensor, liquid level sensor, wiring connection is carried out between current sensor and frequency converter, described analog output module, switching value output module, fault output module is connected with execution unit respectively.Described pressure transducer, flow sensor, liquid level sensor, current sensor and frequency converter are 1 group, and each group at least comprises 1.
The invention has the beneficial effects as follows, the present invention has the advantages such as strong adaptability, result of use are good, easy for installation, and volume is little, cost is low, and in secondary water-supply field, application will have good energy-saving effect and prospect.
