       润滑油温(wen)(wen)度(du)(du)(du)(du)一般(ban)(ban)控制(zhi)在(zai)(zai)35℃－45℃，回油(you)(you)(you)(you)温(wen)(wen)度(du)(du)(du)(du)一般(ban)(ban)要(yao)求65报警(jing)、70停机，通常(chang)(chang)在(zai)(zai)实践中，有(you)(you)些操作手册标准会规定(ding)润(run)(run)滑(hua)(hua)油(you)(you)(you)(you)回油(you)(you)(you)(you)温(wen)(wen)度(du)(du)(du)(du)不超过(guo)65℃。润(run)(run)滑(hua)(hua)油(you)(you)(you)(you)主(zhu)要(yao)有(you)(you)三个(ge)作用(yong)(yong)：一、向各(ge)轴承供油(you)(you)(you)(you)，以(yi)润(run)(run)滑(hua)(hua)和(he)冷(leng)(leng)却(que)(que)轴承各(ge)轴瓦(wa)和(he)推力瓦(wa)，防止烧瓦(wa)；二(er)、供给调节系(xi)(xi)统和(he)保(bao)护装置稳定(ding)充足的(de)(de)(de)(de)压力油(you)(you)(you)(you)；三、供应(ying)各(ge)传动(dong)机构润(run)(run)滑(hua)(hua)用(yong)(yong)油(you)(you)(you)(you)。根据油(you)(you)(you)(you)系(xi)(xi)统的(de)(de)(de)(de)这(zhei)(zhei)个(ge)作用(yong)(yong)，一般(ban)(ban)油(you)(you)(you)(you)系(xi)(xi)统分为润(run)(run)滑(hua)(hua)油(you)(you)(you)(you)系(xi)(xi)统和(he)调节油(you)(you)(you)(you)系(xi)(xi)统两个(ge)部分。所以(yi)对(dui)润(run)(run)滑(hua)(hua)油(you)(you)(you)(you)的(de)(de)(de)(de)压力和(he)温(wen)(wen)度(du)(du)(du)(du)有(you)(you)着严(yan)(yan)(yan)格的(de)(de)(de)(de)规定(ding)和(he)要(yao)求。就润(run)(run)滑(hua)(hua)油(you)(you)(you)(you)的(de)(de)(de)(de)温(wen)(wen)度(du)(du)(du)(du)来说，因为油(you)(you)(you)(you)膜的(de)(de)(de)(de)形成与润(run)(run)滑(hua)(hua)油(you)(you)(you)(you)良(liang)好的(de)(de)(de)(de)粘附(fu)性、一定(ding)的(de)(de)(de)(de)分子(zi)(zi)凝聚力有(you)(you)很大的(de)(de)(de)(de)关系(xi)(xi)，而这(zhei)(zhei)种(zhong)特性由于温(wen)(wen)度(du)(du)(du)(du)有(you)(you)着直接的(de)(de)(de)(de)关系(xi)(xi)，所以(yi)汽轮机在(zai)(zai)选择润(run)(run)滑(hua)(hua)油(you)(you)(you)(you)的(de)(de)(de)(de)时(shi)候要(yao)求也必(bi)须严(yan)(yan)(yan)格，同(tong)样的(de)(de)(de)(de)，运(yun)(yun)行(xing)中对(dui)润(run)(run)滑(hua)(hua)油(you)(you)(you)(you)的(de)(de)(de)(de)温(wen)(wen)度(du)(du)(du)(du)控制(zhi)也有(you)(you)严(yan)(yan)(yan)格要(yao)求。一般(ban)(ban)润(run)(run)滑(hua)(hua)油(you)(you)(you)(you)温(wen)(wen)度(du)(du)(du)(du)控制(zhi)在(zai)(zai)35℃－45℃之间对(dui)油(you)(you)(you)(you)膜的(de)(de)(de)(de)形成*有(you)(you)利，过(guo)高(gao)会导致油(you)(you)(you)(you)质变(bian)质、老化(hua)，影响润(run)(run)滑(hua)(hua)效果(guo)，同(tong)时(shi)轴承回油(you)(you)(you)(you)温(wen)(wen)度(du)(du)(du)(du)过(guo)高(gao)，油(you)(you)(you)(you)的(de)(de)(de)(de)粘度(du)(du)(du)(du)减少，油(you)(you)(you)(you)膜不能(neng)很好建立，影响油(you)(you)(you)(you)膜质量，严(yan)(yan)(yan)重(zhong)时(shi)造(zao)成油(you)(you)(you)(you)膜震(zhen)荡等(deng)事故，并造(zao)成推力瓦(wa)温(wen)(wen)度(du)(du)(du)(du)过(guo)高(gao)，易引(yin)起机组振动(dong)，造(zao)成转子(zi)(zi)动(dong)静摩(mo)擦，损(sun)坏(huai)汽轮机，使机组存在(zai)(zai)危险。当(dang)然，如果(guo)振动(dong)、转子(zi)(zi)晃动(dong)度(du)(du)(du)(du)没有(you)(you)增大趋势，各(ge)瓦(wa)温(wen)(wen)也在(zai)(zai)正常(chang)(chang)范围(wei)，勉强(qiang)(qiang)运(yun)(yun)行(xing)也可(ke)以(yi)，但需要(yao)加(jia)(jia)强(qiang)(qiang)对(dui)TSI各(ge)参数(shu)的(de)(de)(de)(de)监视(shi)，不过(guo)最好是(shi)想办法降油(you)(you)(you)(you)温(wen)(wen)，必(bi)竟这(zhei)(zhei)种(zhong)方式(shi)运(yun)(yun)行(xing)太危险了，建议油(you)(you)(you)(you)温(wen)(wen)不要(yao)长期处于较高(gao)的(de)(de)(de)(de)温(wen)(wen)度(du)(du)(du)(du)，应(ying)采取措(cuo)施(shi)调整(zheng)在(zai)(zai)正常(chang)(chang)范围(wei)，否则一旦出(chu)现故障后果(guo)会相(xiang)当(dang)严(yan)(yan)(yan)重(zhong)。预防冷(leng)(leng)油(you)(you)(you)(you)器(qi)(qi)(qi)润(run)(run)滑(hua)(hua)油(you)(you)(you)(you)温(wen)(wen)度(du)(du)(du)(du)过(guo)高(gao)主(zhu)要(yao)是(shi)对(dui)冷(leng)(leng)油(you)(you)(you)(you)器(qi)(qi)(qi)的(de)(de)(de)(de)清洗工作要(yao)加(jia)(jia)强(qiang)(qiang)，另外(wai)冷(leng)(leng)却(que)(que)水(shui)(shui)(shui)的(de)(de)(de)(de)滤水(shui)(shui)(shui)器(qi)(qi)(qi)滤网要(yao)加(jia)(jia)强(qiang)(qiang)反(fan)冲洗，如果(guo)冷(leng)(leng)油(you)(you)(you)(you)器(qi)(qi)(qi)的(de)(de)(de)(de)出(chu)口温(wen)(wen)度(du)(du)(du)(du)偏(pian)高(gao)，可(ke)以(yi)将(jiang)冷(leng)(leng)油(you)(you)(you)(you)器(qi)(qi)(qi)进行(xing)并列运(yun)(yun)行(xing)，当(dang)循环水(shui)(shui)(shui)水(shui)(shui)(shui)温(wen)(wen)偏(pian)高(gao)时(shi)加(jia)(jia)一些工业水(shui)(shui)(shui)也是(shi)有(you)(you)效的(de)(de)(de)(de)。如果(guo)是(shi)因为冷(leng)(leng)油(you)(you)(you)(you)器(qi)(qi)(qi)换(huan)热面积不够(gou)可(ke)以(yi)增加(jia)(jia)一台(tai)冷(leng)(leng)油(you)(you)(you)(you)器(qi)(qi)(qi)或(huo)将(jiang)其改大；想办法降低冷(leng)(leng)油(you)(you)(you)(you)器(qi)(qi)(qi)冷(leng)(leng)却(que)(que)水(shui)(shui)(shui)进水(shui)(shui)(shui)温(wen)(wen)度(du)(du)(du)(du)。
