Kusanthula ndi kuthetsa zovuta zavuto la excavator lubrication system

Nkhaniyi mwachidule imayambitsa kusanthula zolakwika ndi njira zothetsera mavuto kudzera muzochitika zenizeni za kulephera pang'ono mu dongosolo lapakati lopaka mafuta ofufutira panthawi ya ntchito, ndikuyembekeza kukhala lothandiza kwa abwenzi omwe ali ndi mavuto.

Cholakwika 1:
Pakugwira ntchito kwa fosholo yamagetsi, alamu yolakwika idamveka mwadzidzidzi, ndipo chiwonetsero chazithunzi chowonetsera zidawonetsa: kutsika kwapaipi yamafuta ndi kulephera kwamafuta owuma kumtunda. Pitani kuchipinda chopaka mafuta kuti muyang'ane makina amafuta owuma apamwamba pogwiritsa ntchito kuwongolera pamanja. Yang'anani poyamba ngati thanki yamafuta ili ndi mafuta ochepa, kenaka tembenuzirani kowuni yamafuta owuma kuchokera pamalo odziyimira pawokha kupita pamanja, kenako yang'anani kuthamanga kwa gwero la mpweya komwe kumapereka mpope wa pneumatic. Kupanikizika ndi kwachibadwa, valavu ya solenoid imakhala ndi mphamvu, ndipo pampu ya pneumatic imayamba kugwira ntchito (pampu ndi yachibadwa), pamene kupanikizika kwa payipi kumafika pamtengo wokhazikitsidwa, valve yobwerera kumbuyo imabwerera mwakale, koma mpope wa pneumatic ukugwirabe ntchito. Pambuyo pakuwunikiridwa, vuto la kutuluka kwa mafuta mu payipi yayikulu idachotsedwa koyamba, koma pampu ya pneumatic idapitilirabe kugwira ntchito pambuyo poti valavu yobwerera idasinthidwa (kuwongolera pulogalamu yamagetsi ya PLC ndi: panthawi yogwira ntchito pamanja, valavu yobwerera imabwerera pambuyo pa kukakamizidwa mu payipi imafika pamtengo wokhazikitsidwa, kusintha kwake koyenda kumapereka chizindikiro chamagetsi, valavu ya solenoid yazimitsidwa, ndipo pampu imasiya kugwira ntchito). Zitha kutsimikiziridwa kuti pali vuto penapake mu valve yobwerera. Yang'anani choyamba chosinthira maulendo. Pamene valavu yobwerera ikugwira ntchito, chosinthira choyendayenda chimagwira ntchito bwino. Kenako yang'anani chipangizo chotumizira chizindikiro chosinthira maulendo ndikutsegula chivundikiro cha bokosi. Zikuoneka kuti imodzi mwa mawaya akunja a chipangizo chotumizira chagwa. Mukachilumikiza, yesaninso, zonse zili bwino.

Chifukwa cha kuchepa kwapaipi ya gasi kunachitika. Pambuyo pakuwunika mosamalitsa, zidapezeka kuti valavu yobwerera m'malo owuma owuma amafuta atalephera, valavu ya solenoid idapitilirabe kupatsa mphamvu ndipo pampu ya pneumatic idapitilira kugwira ntchito, zomwe zidapangitsa kuti kupanikizika kwapaipi yayikulu kukhala yotsika kuposa Mtengo wotsika kwambiri wokhazikitsidwa ndi kuponderezana. kwa kuyang'anira kuthamanga kwa mpweya. Kuthamanga kocheperako koyambira kwa kompresa ya mpweya ndi 0.8MPa, ndipo kuthamanga kwanthawi zonse komwe kumayikidwa pa mita yowonetsera mpweya wa thanki yosungiramo mpweya ndi 0.8MPa (mzere waukulu wowunikira kuthamanga kwa mpweya ndiye mtengo wotsika kwambiri wa kuthamanga kwa mpweya wabwinobwino) . Popeza pampu ya pneumatic ikugwirabe ntchito ndikuwononga mpweya, komanso mpweya wa compressor umakhalanso ndi njira yothira madzi potsegulanso, imayeneranso kudya mpweya wina. Mwanjira iyi, kuthamanga kwa mpweya wa chitoliro chachikulu kumakhala kotsika kuposa 0.8MPa, ndipo chipangizo chodziwira kuthamanga kwa mpweya Alamu yapaipi yotsika imamveka.

kusaka zolakwika:
Sinthani kutsitsa koyambira koyambira kwa kompresa ya mpweya kukhala 0.85MPa, ndipo kuthamanga kwanthawi zonse komwe kumayikidwa pa mita yowonetsera mpweya wa thanki yosungiramo mpweya sikunasinthe, komwe kudakali 0.8MPa. Pa opaleshoni yotsatira, panalibe kulephera kwa alamu kwa kuthamanga kwa mzere wochepa.

Pakuwunika kwanthawi zonse, zidapezeka kuti valavu yobwerera m'malo opaka mafuta owuma apamwamba idatenga masekondi opitilira khumi kuposa nthawi zonse. Chochitika choyamba chinali ngati panali kutayikira kwamafuta papaipi yayikulu. , ndikuyang'ana papaipi yayikulu kuchokera ku valavu yobwerera kupita kwa wogawa aliyense, ndipo sanapeze kuti mafuta akutuluka. Onani tanki yamafuta. Mafutawa ndi okwanira. Pakhoza kukhala kutsekeka kwa mapaipi. Sula chitoliro chamafuta cholumikiza pampu ya pneumatic ndi valavu yobwerera. Pambuyo pa ntchito yamanja, kutulutsa mafuta kumakhala koyenera. Vuto likhoza kukhala mu valve yobwerera kumbuyo. Choyamba, masulani chipangizo chosefera pamalo olowera mafuta a valavu yobwerera, chotsani chosefera, ndikupeza kuti pali zinyalala zambiri pazosefera, ndipo gawo lonse la fyuluta latsekedwa pafupifupi theka. (Zitha kukhala zonyansa zomwe zidagwa mu thanki chifukwa cha kusasamala kwa woyendetsa pamene akuwonjezera mafuta). Mukamaliza kuyeretsa, yikani, gwirizanitsani payipi, yambani pampu ya pneumatic, ndipo imagwira ntchito bwino.

Panthawi yofukula, ma alarm omwe amalephera kutulutsa mafuta nthawi zambiri amaperekedwa, zomwe sizingayambike chifukwa cha zovuta zamapaipi kapena zida zopangira mafuta mu dongosolo lopaka mafuta. Izi zikachitika, choyamba fufuzani ngati thanki yamafuta ilibe mafuta, ndiyeno yang'anani zigawo zopangira mafuta (kuphatikizapo valavu ya solenoid yomwe imapereka mpweya ku mpope wa pneumatic) ndi mphamvu ya mpweya wa mpope wa pneumatic motsatizana. Ngati zonse zili bwino, muyenera kugwirizana ndi ogwira ntchito zamagetsi kuti mugwire ntchito limodzi. Yang'anani mawaya amagetsi pazigawo zomwe zimagwirizana ndi dongosolo lopaka mafuta. Kuphatikiza pakupeza ndi kuthana ndi mavuto munthawi yake pakapezeka cholakwika mumayendedwe opaka mafuta, kuwunika koyenera ndi kukonza makina opaka mafuta kuyenera kuchitidwa kuti azindikire ndikuchotsa zoopsa zobisika msanga kuti zitsimikizire kuti zidazo zimagwira ntchito bwino.

Dongosolo lapakati lopaka mafuta limagwiritsa ntchito mafuta apakati kuchokera pa mapampu amafuta ndi mafuta okhazikika munjira yotsekedwa, yomwe imapewa zovuta monga kuipitsidwa kwamafuta ndi kusowa kwamafuta obwera chifukwa cha kudzaza mafuta pamanja. Kugwiritsa ntchito kuwongolera pulogalamu ya PLC, kupezeka kwamafuta pafupipafupi komanso kuchuluka kwamafuta kumapewa zovuta monga kuwononga mafuta opaka mafuta komanso nthawi yothira yolakwika chifukwa cha kudzaza mafuta pamanja. Kaya zolakwika zomwe zimachitika panthawi yogwiritsira ntchito makina opangira mafuta apakati zitha kuyendetsedwa munthawi yake zitha kukhala ndi gawo lofunikira kwambiri pakuwongolera bwino kwa zida.

Ngati excavator wanu ayenera kugula zokhudzanaExcavator Chalkpakukonza ndi kukonza, mutha kulumikizana nafe. Ngati mukufuna kugula excavator yatsopano kapena achofufutira chachiwiri, mutha kulumikizana nafe. CCMIE imapereka ntchito zonse zogulitsa zofukula.
