1.故障现象某厂SHL-10-13型链条锅炉运行时,只要软水泵投入给水自动控制,水泵就会反复产生剧烈振动,使电机与水泵联轴器上柔性胶圈严重损坏,甚至将三爪联轴器撞坏。 2.故障原因该厂锅炉给水流程是:软水箱中的软水→软水泵→热力除氧器水箱→多级泵(或蒸汽泵)→锅炉省煤器→锅筒。在热力除氧器水箱壁上装有UQK-20型 1. Symptom When a plant SHL-10-13-type chain boiler is running, as long as the soft water pump into feed water automatic control, the pump will repeatedly produce violent vibration, the motor and the pump coupling flexible rubber ring on the serious damage, and even three Claw coupling crashed. 2. The cause of the malfunction The boiler feed water process is: soft water in the soft water tank → soft water pump → thermal deaerator tank → multi-stage pump (or steam pump) → boiler economizer → drum. In the thermal deaerator tank wall with UQK-20 type
