維控plc在恒壓供暖系統(tǒng)的應用
一、簡介
供暖系統(tǒng)主要用于北方冬季暖氣系統(tǒng)供暖，控制兩電機對供暖系統(tǒng)水壓控制在恒定范圍內(nèi)，用plc控制減小了工作人員工作量，無需值班人員看守。
二、特點
1、使用維控的PLC，PLC型號為20MT。
2、PLC程序內(nèi)置算法，通過modbus通訊讀取水壓值以及變頻器當前頻率值，當水壓不夠使plc控制變頻器讓補水泵開始工作，一定時間內(nèi)，啟動1#補水泵變頻啟動，變頻一定時間即變頻達到50hz，水壓仍然達不到值，1#補水泵切換到工頻，2#變頻啟動，直到水壓保持在設定值內(nèi)，當水壓恒定在設定值內(nèi)，即1#工頻2#變頻運行，此時如果變頻器頻率低于設定的頻率運行超過設定時間，將自動切換到1#變頻啟動狀態(tài)。2#電機停止運行。
3、系統(tǒng)中還包含無水信號、變頻器故障報警信號。水箱中無水信號、變頻器故障報警信號送達plc，系統(tǒng)停止工作。
三、組成部分
1、PLC負責動作的直接控制和外界反饋的信息的采集，實現(xiàn)供水系統(tǒng)的自動運作和故障檢測。
