一般生產(chǎn)的U型螺栓材質(zhì)有:Q235鋼、45#鋼、4硼鋼、2錳鈦硼鋼。其中9%以上的都是以Q235鋼為原材料生產(chǎn)的。Q235鋼為原材料生產(chǎn)出來(lái)的等級(jí)是4.8級(jí),這種材質(zhì)的特點(diǎn)是耐高溫。Q345b料就是16猛,特點(diǎn)是粘度大,有韌性45#它的等級(jí)是8.8級(jí),耐高溫,45#做螺栓的話,它調(diào)不到1.9級(jí),如何45#做螺母的話,能調(diào)到1.9級(jí)(調(diào)質(zhì)就是用火燒)35Crmoa它的等級(jí)是1.9級(jí)到12.9級(jí),耐高溫,有耐性粘度大Q345b就是16錳材質(zhì),它的特點(diǎn)是耐低溫1°,有彈性4Cr材質(zhì)(讀法是4洛)要比45#好,能調(diào)質(zhì)到1.9級(jí),調(diào)質(zhì)的目的是為了有韌性。
IKO軸承溫度升高的原因：軸承冷卻水中斷。油質(zhì)劣化，油自身不清潔或運(yùn)行中油劣化，如油中的水分增加會(huì)引起油的酸性增大，會(huì)降低油的潤(rùn)滑作用，使軸瓦遭到腐蝕，造成軸承溫度升高?，F(xiàn)象：有警報(bào)電鈴響.機(jī)旁盤(pán)水輪機(jī)械故障光字牌亮，指示IKO軸承溫度的儀表溫度升高，信號(hào)繼電器動(dòng)作。溫度計(jì)盤(pán)（膨脹型溫度計(jì)）黑針與黃針重合或超過(guò)黃針。發(fā)出軸承溫度升高的故障信號(hào)。處理當(dāng)IKO軸承溫度升高時(shí)，首先判斷是否誤動(dòng)作，如確實(shí)升高，應(yīng)做如下處理：檢查冷卻水水壓，水流及管路系統(tǒng)是否正常。

PLC
處理器(CPU)由控制器、運(yùn)算器和寄存器組成并集成在一個(gè)芯片內(nèi)。CPU通過(guò)數(shù)據(jù)總線總線、地址總線、控制總線和電源總線與存儲(chǔ)器、輸入輸出接口、編程器和電源相連接。
小型PLC的CPU采用8位或16位微處理器或單片機(jī)，如8031、M68000等，這類(lèi)芯片價(jià)格很低；中型PLC的CPU采用16位或32位微處理器或單片機(jī)，如8086、96系列單片機(jī)等，這類(lèi)芯片主要特點(diǎn)是集成度高、運(yùn)算速度快且可靠性高；而大型PLC則需采用高速位片式微處理器。
CPU按照PLC內(nèi)系統(tǒng)程序賦予的功能指揮PLC控制系統(tǒng)完成各項(xiàng)工作任務(wù)
