Variable-frequency constant-pressure water supply device, water supply method and fault detection method
The invention discloses a variable-frequency constant-pressure water supply device, a water supply method and a fault detection method. The variable-frequency constant-pressure water supply device comprises a pressure sensor, a flow switch and a PLC. The pressure sensor is connected with the PLC and used for detecting the current water outlet pressure in real time and outputting a pressure signal to the PLC. The flow switch is connected with the PLC and used for detecting the water supply flow of the water supply device and outputting a water supply flow signal to the PLC; and the PLC is used for controlling the start and/or stop of the corresponding water pump and the fault detection of the water supply device according to the received water outlet pressure signal and water supply flow signal. Switching of the water pumps is effectively controlled by measuring the water supply flow and the water outlet pressure, fault detection is carried out on the water supply device, the whole water supply system is made to be in an efficient operation state, and the water supply device is prevented from breaking down to cause water cut-off accidents.
本发明公开了一种变频恒压供水装置、供水方法及故障检测方法，包括压力传感器、流量开关和PLC控制器；所述压力传感器与所述PLC控制器连接，用于实时检测当前的出水压力并输出压力信号至PLC控制器；所述流量开关与所述PLC控制器连接，用于检测供水装置的供水流量并输出供水流量信号至PLC控制器；所述PLC控制器用于根据接收到的所述出水压力信号和供水流量信号控制相应的水泵启动和/或停止，以及供水装置的故障检测。本发明实施例通过测量供水流量和出水压力有效的控制水泵的切换，以及对供水装置进行故障检测，使整个供水系统处于高效运行状态，以及防止供水装置出现故障造成停水的事故。
