山海關(guān)船廠800T壓機(jī)維修

所屬分類:

機(jī)械應(yīng)用與工程

一﹑設(shè)備概況

 

1.客戶名稱:山海關(guān)船舶重工有限責(zé)任公司

 

2.設(shè)備名稱:800T單臂油壓機(jī)

 

3.出廠時間及制造單位:1978年陜西壓延設(shè)備廠制造,1982年山船購置使用。

 

4.存在主要問題:此臺設(shè)備于1982年購置,使用至今相關(guān)液壓管道及部件已老化嚴(yán)重,主缸及提升缸密封圈密封性較差,導(dǎo)致主缸工作壓力不足,不能滿足工作需要,大量液壓油滲漏,造成能源浪費(fèi)和生產(chǎn)環(huán)境的污染。

                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                   

二﹑主要修理項(xiàng)目

大修包括:

1.主缸兩套、提升缸四套、懸臂吊旋轉(zhuǎn)油缸兩套;

2.整個液壓系統(tǒng)翻新;

3.外部管路更新,包括軟管和鋼管;

4.解決了現(xiàn)存故障,并恢復(fù)該油壓機(jī)原設(shè)計(jì)加工精度、加工能力;

5.整機(jī)修復(fù)各項(xiàng)功能帶負(fù)荷試車,各溫度、振動、密封效果良好,得到客戶的認(rèn)可和贊許。在要求工期內(nèi)圓滿完成任務(wù),為船體車間修船生產(chǎn)提供了有力保障。
