威海(hai)(hai)力建冶金液(ye)壓(ya)(ya)(ya)(ya)(ya)設(she)(she)備(bei)廠座落在膠東半(ban)島美麗(li)的(de)(de)海(hai)(hai)濱(bin)城市----威海(hai)(hai)，主要生(sheng)產重載液(ye)壓(ya)(ya)(ya)(ya)(ya)缸、標準液(ye)壓(ya)(ya)(ya)(ya)(ya)缸、工(gong)程(cheng)液(ye)壓(ya)(ya)(ya)(ya)(ya)缸、車(che)輛(liang)液(ye)壓(ya)(ya)(ya)(ya)(ya)缸、拉桿多液(ye)壓(ya)(ya)(ya)(ya)(ya)缸、液(ye)壓(ya)(ya)(ya)(ya)(ya)系統等系列多種(zhong)(zhong)規格(ge)設(she)(she)備(bei)及液(ye)壓(ya)(ya)(ya)(ya)(ya)元件。可以根據(ju)用(yong)(yong)戶需要設(she)(she)計制造(zao)各種(zhong)(zhong)工(gong)程(cheng)用(yong)(yong)、冶金用(yong)(yong)標準和非標準液(ye)壓(ya)(ya)(ya)(ya)(ya)（氣）缸及冶金、礦山(shan)、化工(gong)、交通等行業用(yong)(yong)液(ye)壓(ya)(ya)(ya)(ya)(ya)系統。同時還從事特種(zhong)(zhong)鑄(zhu)造(zao)設(she)(she)備(bei)（離心(xin)鑄(zhu)造(zao)機、低壓(ya)(ya)(ya)(ya)(ya)鑄(zhu)造(zao)機）的(de)(de)研發﹑設(she)(she)計、制造(zao)及安裝(zhuang)調試和咨詢(xun)服(fu)務。

(5)液(ye)壓(ya)缸(gang)初(chu)始動(dong)(dong)(dong)作緩(huan)慢(man)。在(zai)溫(wen)(wen)度較低的情(qing)況下，液(ye)壓(ya)油(you)黏度大，流動(dong)(dong)(dong)性差，導致(zhi)液(ye)壓(ya)缸(gang)動(dong)(dong)(dong)作緩(huan)慢(man)。改善(shan)方法是，更換黏溫(wen)(wen)性能較好的液(ye)壓(ya)油(you)，在(zai)低溫(wen)(wen)下可借助加(jia)熱器或用機器自(zi)身加(jia)熱以(yi)提升啟動(dong)(dong)(dong)時(shi)的油(you)溫(wen)(wen)，系統正常(chang)工作油(you)溫(wen)(wen)應保持在(zai)40℃左(zuo)右。

2、工作時(shi)不能驅動負載

主要表現為活塞桿停位不準、推力不足、速度下降、工作不穩定等,其原(yuan)因是：

一(yi)(yi)般(ban)地說(shuo)，測量(liang)(liang)(liang)時造(zao)成深(shen)度(du)不大的細長(chang)形(xing)(xing)劃傷(shang)是(shi)輕微的，不影響運行精度(du)，但如(ru)果(guo)測量(liang)(liang)(liang)桿頭(tou)(tou)尺寸調節(jie)不當(dang)，測量(liang)(liang)(liang)觸頭(tou)(tou)硬行嵌入(ru)，會造(zao)成較為重(zhong)度(du)的傷(shang)痕。解決此問題的對策，首(shou)先(xian)是(shi)測量(liang)(liang)(liang)出調節(jie)好(hao)的測量(liang)(liang)(liang)頭(tou)(tou)的長(chang)短度(du)，此外(wai)，用一(yi)(yi)張(zhang)只在(zai)測量(liang)(liang)(liang)位置上開孔的紙帶，貼在(zai)缸壁內(nei)表(biao)面，即(ji)不會產生(sheng)上述(shu)形(xing)(xing)狀劃痕。測量(liang)(liang)(liang)造(zao)成的輕微劃痕，一(yi)(yi)般(ban)用舊(jiu)砂(sha)布的反面或(huo)馬糞紙即(ji)可擦去。
