?液壓泵在長(zhǎng)期運(yùn)作過(guò)程中難免出現(xiàn)一些問(wèn)題,這些問(wèn)題一般是由于潤(rùn)滑油過(guò)少、油壓過(guò)低或管路泄漏等原因引起這些問(wèn)題一般都是由于潤(rùn)滑不良所引起潤(rùn)滑油的好壞直接影響液壓泵性能潤(rùn)滑油老化后不但會(huì)引起油中雜質(zhì)的沉積和潤(rùn)滑油變質(zhì),而且會(huì)產(chǎn)生許多化學(xué)變化以及金屬表面的氧化等反應(yīng)產(chǎn)生高溫污染環(huán)境。
如果長(zhǎng)期使用這種潤(rùn)滑油,液壓泵的油封便會(huì)損壞,而且液壓泵的潤(rùn)滑狀況也會(huì)發(fā)生變化這些損壞也會(huì)導(dǎo)致液壓泵出現(xiàn)故障 1、換油時(shí)注意油液溫度,在溫度高的環(huán)境下?lián)Q油要加注低粘度的潤(rùn)滑劑,因?yàn)楦哒扯葷?rùn)滑油不僅降低了潤(rùn)滑效果,而且油液在流動(dòng)過(guò)程中與空氣發(fā)生氧化作用,破壞了液壓泵的內(nèi)部機(jī)械密封,使密封件失效; 在換油時(shí)要注意檢查各部件油位是否在正常范圍內(nèi)。
因此要嚴(yán)格按設(shè)計(jì)的油位換油,并應(yīng)及時(shí)換油,保證液壓泵的正常運(yùn)轉(zhuǎn)換油時(shí)應(yīng)在油箱內(nèi)加入適量的標(biāo)號(hào)為SAF的柴油,并添加適量的液壓油但應(yīng)注意使用油量要符合要求,以免液壓油過(guò)于稠密而使摩擦副過(guò)度磨損在液壓泵機(jī)的工作中,經(jīng)常會(huì)出現(xiàn)一些故障,所以在維修和使用液壓機(jī)油時(shí)需要注意一些細(xì)節(jié)問(wèn)題。
例如:一些液壓機(jī)油如果不正確的使用便會(huì)造成機(jī)件變形、損壞,因此在使用液壓機(jī)油時(shí)需要正確操作使用方法并且保持油液暢通,同時(shí)還應(yīng)該定期地對(duì)機(jī)件進(jìn)行保養(yǎng)以及清洗那么液壓機(jī)油質(zhì)量如何才能得到保證呢? 2、換油時(shí)應(yīng)注意控制油量,當(dāng)油量過(guò)多時(shí)(或太少)會(huì)使?jié)櫥到y(tǒng)中的油液過(guò)量損耗或發(fā)生雜質(zhì)沉積堵塞油路; 還可能產(chǎn)生高溫,加速零件的腐蝕和磨損;此外,如果長(zhǎng)時(shí)間不更換潤(rùn)滑油,將導(dǎo)致潤(rùn)滑油膜厚度減少,使?jié)櫥阅芙档?,從而降低了液壓系統(tǒng)的抗磨能力.(注:因在液壓系統(tǒng)中長(zhǎng)期工作,需更換潤(rùn)滑油)對(duì)液壓裝置的損壞嚴(yán)重。
應(yīng)在每次換油時(shí)換入適當(dāng)容量的潤(rùn)滑油一般情況下,每100-120小時(shí)需換一次油用液壓泵換油時(shí),應(yīng)先將液壓泵裝上試運(yùn)轉(zhuǎn)幾次,以保證液壓系統(tǒng)得到良好的潤(rùn)滑若試運(yùn)轉(zhuǎn)后仍不能正常工作怎么辦?這時(shí)應(yīng)檢查各部件安裝是否合理、各油缸工作是否正常。
如果液壓缸工作正常而且磨損量也不大,可將試運(yùn)轉(zhuǎn)幾次后,還沒(méi)造成損壞時(shí)再進(jìn)行更換(注:試運(yùn)轉(zhuǎn)一定要由經(jīng)驗(yàn)豐富的專(zhuān)業(yè)人員完成) 90-R-075-MA-1-CD-80-S-3-S1-D-03-GBA-35-35-24 90R075MA1CD80S3S1D03GBA353524 90-R-075-MA-1-CD-80-S-3-S1-E-03-GBA-32-32-24 90R075MA1CD80S3S1E03GBA323224 90-R-075-MA-1-CD-81-P-3-S1-D-03-GBA-32-32-20 90R075MA1CD81P3S1D03GBA323220 90-R-075-MA-1-CD-81-P-3-S1-D-04-GBA-32-32-20 90R075MA1CD81P3S1D04GBA323220 90-R-075-MA-1-NN-60-L-3-C6-E-03-GBA-29-29-20 90R075MA1NN60L3C6E03GBA292920 90-R-075-MA-1-NN-60-L-3-C6-E-03-GBA-42-42-24 90R075MA1NN60L3C6E03GBA424224 90-R-075-MA-1-NN-60-L-3-S1-D-03-GBA-32-32-24 90R075MA1NN60L3S1D03GBA323224 90R075-MA-1-NN-60-L-3-S1-D-03-GBA-32-32-24 90R075MA1NN60L3S1D03GBA323224 90-R-075-MA-1-NN-60-L-3-S1-D-03-GBA-42-42-24 90R075MA1NN60L3S1D03GBA424224 90-R-075-MA-1-NN-60-L-3-S1-D-04-GBA-42-42-24 90R075MA1NN60L3S1D04GBA424224 90-R-075-MA-1-NN-60-L-4-C6-D-04-GBA-35-35-24 90R075MA1NN60L4C6D04GBA353524 90-R-075-MA-1-NN-60-P-3-C6-D-03-GBA-35-35-24 90R075MA1NN60P3C6D03GBA353524 90-R-075-MA-1-NN-60-P-3-C7-D-03-GBA-42-42-24 90R075MA1NN60P3C7D03GBA424224 90-R-075-MA-1-NN-60-P-3-S1-D-03-GBA-35-35-20 90R075MA1NN60P3S1D03GBA353520 90-R-075-MA-1-NN-60-P-3-S1-D-03-GBA-35-35-24 90R075MA1NN60P3S1D03GBA353524 90-R-075-MA-1-NN-60-P-3-S1-D-04-GBA-35-35-20 90R075MA1NN60P3S1D04GBA353520 90-R-075-MA-1-NN-60-R-3-S1-D-03-GBA-20-20-24 90R075MA1NN60R3S1D03GBA202024 90-R-075-MA-1-NN-60-R-3-S1-D-03-GBA-35-35-24 90R075MA1NN60R3S1D03GBA353524 90-R-075-MA-1-NN-60-S-3-C6-D-03-GBA-35-35-24 90R075MA1NN60S3C6D03GBA353524 90-R-075-MA-1-NN-60-S-3-C6-E-03-GBA-42-42-24 90R075MA1NN60S3C6E03GBA424224 90R075-MA-1-NN-60-S-3-C7-D-03-GBA-26-26-24 90R075MA1NN60S3C7D03GBA262624 90-R-075-MA-1-NN-60-S-3-C7-D-03-GBA-26-26-24 90R075MA1NN60S3C7D03GBA262624 90-R-075-MA-1-NN-60-S-3-C7-D-03-GBA-29-14-20 90R075MA1NN60S3C7D03GBA291420 90-R-075-MA-1-NN-60-S-3-C7-D-03-GBA-35-35-24 90R075MA1NN60S3C7D03GBA353524 90-R-075-MA-1-NN-60-S-3-C7-D-03-GBA-42-42-20 90R075MA1NN60S3C7D03GBA424220 90R075-MA-1-NN-60-S-3-C7-D-03-GBA-42-42-24 90R075MA1NN60S3C7D03GBA424224 90-R-075-MA-1-NN-60-S-3-C7-D-03-GBA-42-42-24 90R075MA1NN60S3C7D03GBA424224 90-R-075-MA-1-NN-60-S-3-S1-D-03-GBA-14-14-24 90R075MA1NN60S3S1D03GBA141424 90-R-075-MA-1-NN-60-S-3-S1-D-03-GBA-26-26-24 90R075MA1NN60S3S1D03GBA262624 。
