绿联净化Leelool黑烟净化器旁通系统

Leelool DPF Bypass System

前言

在黑烟净化器中，旁通系统承担着开/闭旁通管路从而控制废气流向的作用。黑烟净化器正常工作时，旁通系统关闭，发动机尾气通过净化器处理后排出。黑烟净化器对启动黑烟处理完成后，旁通系统自动打开，发动机尾气通过旁通管道直接排出。

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.

旁通系统不仅是确保黑烟净化器正常运行的核心部件，更是确保发动机运行和操作人员人身的关键因素。因此，在黑烟净化器的选择、安装和维护中，整个旁通系统的性能和可靠性尤为重要。

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.

旁通机构的组成

①旁通机构（阀体，阀芯/阀板，阀杆，执行器：陶瓷端子、耐高温护套信号控制线，漆包线耐高温处理）；②旁通管（等于净化器进/出口烟管直径）；③压力信号采集及传输：压力传感器要安装散热管+散热翅片；④控制系统：电控箱、控制模块、继电器、指示灯、按钮及控制线路。作用是净化器工作状态显示，采集的信号处理，输出信号给旁通系统进行开/闭。

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.
