简介:摘要吹瓶机的耐腐蚀模壳,它的主要改良是将原来在铝制模壳两端的冷却水回路改在不锈钢端盖上。这是一种组合壳体并不是一体的,它由两个对半壳体组成,在外形上壳体呈半环状,壳体沿平行于轴线方向开设有若干上下贯穿的冷却孔,而且在壳体的上下两端分别安装有不锈钢上端盖和不锈钢下端盖,不锈钢上端盖开设有分别与外侧的两个冷却孔连通的进水口和出水口,不锈钢上端盖和不锈钢下端盖正对壳体一端均开设有连通相邻两个冷却孔的密封槽。本模壳在壳体的上下两端分别安装有不锈钢上端盖和不锈钢下端盖,不锈钢上端盖和不锈钢下端盖正对壳体一端均开设有密封槽,能够连通壳体上相邻两个冷却孔,从而形成一段冷却水路,能够充分冷却壳体,而且密封槽耐腐蚀。
简介:摘要:港口门机滑环箱电缆头及其他电气元件常因结露造成绝缘性能下降,发生电力故障,影响设备运行,给企业生产造成损失。因此,技术人员需要定期对进线电缆进行预防性试验,包括电力电缆绝缘电阻试验和电力电缆直流耐压试验。通过对电缆故障原因的分析,提出了相关技术措施。经长期检查发现,滑环箱内进线电缆等设备绝缘性能良好,表明提出的措施是有效可行的。
