我厂锅炉房有两台9L250型多斗式提升机,使用中故障频繁。经常发生调节螺杆或轴弯曲,有时断链甚至造成停炉。经分析原因与寻找对策,使问题得以解决。现介绍如下。一、故障原因 1.送料过多人工送料,容易造成给料过量,积聚在提升机下部(有时堆积高度达1m),积料挤压、摩擦料斗,造成超载而拉弯调节螺杆或轴。 2.煤湿遇雨雪天气时,湿煤粘附在料斗和下料管上,使输送量减少。但给料并未减少,故造成堵塞料管、拉坏设备。 Our boiler room has two 9L250 multi-bucket elevator, frequent use of the fault. Frequent adjustment screw or shaft bending, and sometimes even broken chain caused shutdown. After analyzing the reasons and finding countermeasures, the problems can be solved. Now introduced as follows. First, the cause of the malfunction 1. Feed too much artificial feeding, easily lead to overdose, accumulated in the lower part of the hoist (sometimes stacking height of 1m), the material extrusion, friction hopper, causing overload and bending adjustment screw or shaft. 2. Coal wet rainy weather, the wet coal sticking in the hopper and the lower tube, so that the delivery volume reduced. However, the feed did not reduce, it caused blockage tube, pull bad equipment.
