B.基爾波申(KирпоциН)在研究鋼球硬度對(duì)磨礦指標(biāo)的影響時(shí)指出,實(shí)驗(yàn)室試驗(yàn)證明,鋼球?qū)Ω鞣N類(lèi)型的礦石都存在一個(gè)硬度的問(wèn)題。按此說(shuō)法,各種礦石的硬度值均不相同。這個(gè)說(shuō)法是有道理的,值得進(jìn)一步研究。我國(guó)首鋼大石河鐵礦的生產(chǎn)應(yīng)用有力說(shuō)明這個(gè)問(wèn)題。大石河鐵礦1981~1983年使用了4種不同硬度的鋼球,各種球磨礦時(shí)的磨機(jī)利用系數(shù)說(shuō)明:不同硬度鋼球有不同磨礦效果,但并非硬度的效果好,而是硬度恰當(dāng)時(shí)效果才,2MnV鍛鋼球生產(chǎn)率,但HRC僅3~4,硬度恰當(dāng)。

與L80-13Cr管材一樣,TP110-SUP13Cr鋼級(jí)油套管只能采用無(wú)縫鋼管生產(chǎn)。由于TP110-SUP13Cr管坯的變形抗力大,穿孔、連軋工序的軋制力均高于普通碳鋼,生產(chǎn)薄壁油管時(shí),軋制力更是超出設(shè)備設(shè)計(jì)能力,跳電停機(jī)的隱患大。同時(shí),鋼管的內(nèi)、外表面缺陷較軋制普通碳鋼產(chǎn)品時(shí)更易出現(xiàn),軋制工具壽命明顯縮短,導(dǎo)盤(pán)、頂頭、芯棒容易粘鋼、磨損,缺陷率很高。傳統(tǒng)的熱軋鋼管生產(chǎn)工藝很難保證TP110-SUP13Cr薄壁油管的軋制質(zhì)量與軋制效率。

可見(jiàn),泵的安全運(yùn)行與整個(gè)國(guó)民經(jīng)濟(jì)的發(fā)展密切相關(guān),泵的維護(hù)和檢修至關(guān)重要。維護(hù)的類(lèi)型1.1事故后維護(hù)這種維護(hù)方法允許機(jī)械工作到有明顯故障發(fā)生,采取的措施是將損壞的設(shè)備或元件拆下來(lái)進(jìn)行修理或更新。這樣維修的費(fèi)用高且浪費(fèi)時(shí)間,耽誤正常生產(chǎn)。這種方法另一個(gè)缺點(diǎn)就是維修部門(mén)一直處于“救火隊(duì)”的緊張狀態(tài),為了“快速反應(yīng)”,就必須準(zhǔn)備好各種零配件以供替換;配備更多維修工人來(lái)應(yīng)付突如其來(lái)的緊急情況。還有可能出現(xiàn)的情況是,這里的問(wèn)題還沒(méi)完全解決,那里又出現(xiàn)了更嚴(yán)重的故障,工人被迫疲于奔命。
