綠聯凈化Leelool黑煙凈化器旁通系統
Leelool DPF Bypass System
前言
在黑煙凈化器中，旁通系統承擔著開/閉旁通管路從而控制廢氣流向的作用。黑煙凈化器正常工作時，旁通系統關閉，發動機尾氣通過凈化器處理后排出。黑煙凈化器對啟動黑煙處理完成后，旁通系統自動打開，發動機尾氣通過旁通管道直接排出。
In DPF, the bypass system plays a role in opening or closing the bypass pipeline to control the flow of exhaust gas.When DPF is working normally, the bypass system is closed and the engine exhaust is purified by the purifier before being discharged.After the DPF completes the exhaust treatment during startup, the bypass system opens and the engine exhaust is directly discharged through the bypass pipe.
旁通系統不僅是確保黑煙凈化器正常運行的核心部件，更是確保發動機運行和操作人員人身的關鍵因素。因此，在黑煙凈化器的選擇、安裝和維護中，整個旁通系統的性能和可靠性尤為重要。
The bypass system is not only the core component for the normal operation of the exhaust purifier,but also a key factor in ensuring the safe operation of the engine and the personal safety of the operators.Therefore,in the selection, installation,and maintenance of exhaust purifiers,the performance and reliability of bypass system are particularly important.
旁通機構的組成
①旁通機構（閥體，閥芯/閥板，閥桿，執行器：陶瓷端子、耐高溫護套信號控制線，漆包線耐高溫處理）；②旁通管（等于凈化器進/出口煙管直徑）；③壓力信號采集及傳輸：壓力傳感器要安裝散熱管+散熱翅片；④控制系統：電控箱、控制模塊、繼電器、指示燈、按鈕及控制線路。作用是凈化器工作狀態顯示，采集的信號處理，輸出信號給旁通系統進行開/閉。
①Bypass mechanism (valve body, valve core and valve plate, valve stem, actuator: ceramic terminal, high temperature resistant sheath signal control wire, enameled wire with high temperature resistance treatment).②Bypass pipe (equal to the diameter of the inlet or outlet smoke pipes of the purifier).③Pressure signal acquisition and transmission: The pressure sensor should be equipped with a heat pipe and heat dissipation fins.④Control system: electrical control box, control module, relay, indicator light, button and control circuit. The function is to display the working status of the purifier, process the collected signals, and output signals to the bypass system for opening or closing.
