江苏省大丰县化肥厂SHL10—25/400型锅炉从1981年8月正式投入运行,总的性能是良好的,唯前轴与右轴承于当年年底不到一个月时间连续发生两次咬死事故,全厂停车2—3天。一、事故原因分析原结构(见图1)前轴与两端铸铁轴承配合,两头有端盖轴与变速箱用靠背轮联接,前轴转速分为四档为2.03转/时、2.57转/时、5.15转/时、6.72转/时轴承盖和轴承开有Φ4油孔,用黄油润滑,采用市场接头式注油杯压入。该厂第一次分析咬死的原因是失油,因原结构油孔直径太小仅4毫米,且距离长,还有
Dafeng County, Jiangsu Province, fertilizer plant SHL10-25 / 400 boiler officially put into operation in August 1981, the overall performance is good, only the front axle and the right bearing at the end of the year less than a month time occurred two consecutive deaths , The whole plant parking 2-3 days. First, the cause of the accident analysis of the original structure (see Figure 1) front axle and cast iron bearings at both ends, both ends of the cover shaft and gearbox with the back wheel coupling, the front axle speed is divided into fourth gear 2.03 rev / h, 2.57 rev / When 5.15 rev / h, 6.72 rev / h bearing cap and bearing open a hole Φ4, with butter lubrication, the use of the market connector-type injection cup into. The first analysis of the plant was killed because of oil loss, because the original structure of oil hole diameter is too small, only 4 mm, and the distance is long, and
