KZL2-8卧式快装锅炉的链条炉排传动是依靠液压驱动机构来实现的,并依靠溢流阀的溢流来保证液压系统具有恒定的压力。由于链条炉排是间歇动作,活塞缸的液压油进出口每隔40s就换向一次,这时压力表的指针随着起压、复位而摆动。如此频繁的工作,使压力表容易损坏。我厂自1987年安装该锅炉以来,压力表已经换了10余块。原有的缓冲盘管根本不起缓冲 KZL2-8 horizontal fast boiler chain grate drive is relying on the hydraulic drive mechanism to achieve, and rely on relief valve overflow to ensure that the hydraulic system has a constant pressure. As the chain grate is intermittent action, piston hydraulic oil import and export every 40s on the change, then the pressure gauge pointer with the starting pressure, reset and swing. Such frequent work makes the pressure gauge easy to damage. I plant since the installation of the boiler in 1987, the pressure gauge has changed more than 10 pieces. The original buffer coil can not afford to be buffered
