Ndife akatswiri pazigawo za injini zapamwamba kwambiri.
Chilankhulo
Udindo wa mpope wamafuta pamakina opaka mafuta: Ntchito ya mpope wamafuta ndikukweza mafuta kukakamiza kwina ndikukakamiza kutsika kwapansi kupita kumalo osuntha a injini.
Mapangidwe a pampu yamafuta amatha kugawidwa mumtundu wa zida ndi mtundu wa rotor.
Pampu yamafuta yamtundu wa gear imagawidwa mumtundu wa zida zamkati ndi mtundu wa zida zakunja, zomwe nthawi zambiri zimatchedwa pampu yamafuta yamafuta.
Pampu yamafuta Mu makina opangira mafuta, chipangizo chomwe chimakakamiza mafuta kuchokera ku poto kupita ku magawo a injini.
Pampu yamafuta imagwiritsidwa ntchito kukulitsa kupanikizika kwamafuta ndikuwonetsetsa kuchuluka kwamafuta, mpaka pamakangano amtundu wokakamiza wamafuta.
▶ Mtundu wa giya ndi mpope wamafuta amtundu wa rotor amagwiritsidwa ntchito kwambiri pamainjini oyatsira mkati.
▶Pampu yamafuta yamtundu wa gear ili ndi ubwino wamapangidwe osavuta, kukonza kosavuta, ntchito yodalirika, moyo wautali wautumiki komanso kuthamanga kwapampu, kotero yakhala ikugwiritsidwa ntchito kwambiri.
▶ Mawonekedwe a rotor pump rotor ndi ovuta, zitsulo zamitundu yambiri za ufa. Pampu iyi ili ndi zabwino zomwezo ngati pampu yamagetsi, koma mawonekedwe ophatikizika, voliyumu yaying'ono, ntchito yosalala, phokoso lochepa.
▶Chiwerengero cha mano ozungulira mkati ndi kunja a pampu ya cycloid rotor ndi kusiyana kumodzi kokha. Akamasuntha pang'onopang'ono, liwiro lotsetsereka la dzino ndi laling'ono, ndipo meshing point imayenda motsatira mbiri ya dzino la mkati ndi kunja kwa rotor.
▶Choncho, kuvala kofanana kwa malo awiri ozungulira mano kumakhala kochepa.
①Mapangidwe ndi mfundo zogwirira ntchito pampu yamafuta
▶Pampu yamafuta imapangidwa ndi rotor yakunja ndi rotor yamkati yomwe imapangidwa pakati pa thupi la mpope ndi chivundikiro cha mpope ndipo imakhala yofanana muutali ndi bowo la pampu.
▶Chilolezo cha radial pakati pa rotor yakunja ndi thupi la mpope nthawi zambiri chimakhala 0.09 ~ 0.12mm, chilolezo cha meshing pakati pa rotor yamkati ndi yakunja ndi 0.07 ~ 0.12mm, ndipo chilolezo pakati pa rotor yamkati ndi yakunja ndi chivundikiro cha mpope ndi 0.03 ~ 0.075 mm.
▶ Dongosolo lowongolera (lochepetsa) papampu yamafuta limapangidwa ndi pulagi, pulagi ndi pulagi. Ntchito yake ndikuwongolera kuthamanga kwa potulutsa mafuta pampu yamafuta.
②Kugawa pampu yamafuta
▶▶pompa zida zakunja
Bungwe:Magiya awiri okhala ndi nambala yofanana ya mano, nyumba, polowera mafuta, potulutsira mafuta, valavu yothandizira, ndi zina.
Njira yogwirira ntchito: Magiya awiriwa amayenda mothamanga kwambiri.
① Doko lamafuta, magiya awiri otuluka mu meshing, kuti voliyumu ya chipinda cholowera mafuta chiwonjezeke, kuyamwa, mafuta kudzera mu poto yamafuta kupita kuchipinda chamafuta.
② Kutulutsa kwamafuta, magiya awiriwa ali pafupi ndi ma meshing, komanso kuchuluka kwa chipinda chotulutsa.
▶▶Pompu ya mkati mwa meshing gear
Kapangidwe:Mano amkati, mano akunja, sitepe yooneka ngati kanyenyezi, polowera mafuta, potulutsa mafuta, chipolopolo, etc.
Njira yogwirira ntchito:Mano amkati amayendetsedwa ndi crankshaft, ndipo mano akunja ndi zida zoyendetsedwa.
① doko lamafuta; Mano amkati ndi akunja alibe ma meshing, ndipo kuchuluka kwa chipinda chamafuta kumawonjezeka, kutulutsa kuyamwa, ndipo mafuta amalowetsedwa muchipinda chamafuta kudzera mupoto wamafuta.
② mafuta; Magiya amkati ndi akunja ali pafupi ndi ma meshing, kuchuluka kwa chipinda chotulutsira mafuta kumachepa, kupanikizika kumawonjezeka, ndipo mafuta amatuluka m'chipinda chotulutsira mafuta.
▶▶Pompu yamafuta a rotor
Kapangidwe; Rotor yamkati ndi yakunja, polowera mafuta, potulutsira mafuta, kapangidwe ka zipolopolo.
Ø khalidwe;Rotor yamkati imagwira ntchito, rotor yakunja imayendetsedwa, yamkati yamkati imakhala yochepa kuposa yakunja ya dzino, mkati ndi kunja kwa rotor eccentric install.
Njira yogwirira ntchito;
1.Kulowetsa mafuta; Rotor yamkati ndi yakunja yotuluka mu meshing, kuchuluka kwa chipinda chamafuta kumawonjezeka, kuyamwa, mafuta kudzera mu poto yamafuta kulowa mchipinda chamafuta.
2.kutulutsa mafuta; Ma meshes amkati ndi akunja a rotor, kuchuluka kwa chipinda chotulutsira mafuta kumachepa, kupanikizika kumawonjezeka, ndipo mafuta amatuluka m'chipinda chotulutsira mafuta.
③Kusanthula kosafala kwa pampu yamafuta
▶▶Kuthamanga kwamafuta ochepa, kusakwanira kwamafuta, kumveka kwa injini yachilendo, komanso kumapangitsa kuti matailosi ndi shaft kulephera.
1.Chifukwa chake ndi chakuti kutuluka kwa mpope wamafuta kumakhala kochepa, komwe kungayambitsidwe ndi kutsegulira koyambirira kwa valve yochepetsera kuthamanga kapena mkati ndi kunja kwa rotor, rotor ndi pampu thupi, ndi kusiyana pakati pa chivundikiro cha mpope ndi rotor ndi yayikulu kwambiri.
2.Nthawi zina rotor yamkati sichimangirizidwa mwamphamvu ndi shaft, ndipo shaft sichimatembenuka ikatembenukira ku rotor yamkati, yomwe imakhalanso chifukwa cha kuchepa kwa pampu ya mafuta.
▶▶Kukwera kwamafuta kumapangitsa kuti injiniyo izitaya mphamvu, kusokoneza kutulutsa kwamafuta osindikiza.
1.Pamene kupanikizika kuli kwakukulu, kudzawononga chinthu cha fyuluta ya mafuta, kotero kuti mafuta sangathe kusefedwa.
2.Chomwe chimapangitsa kuti mafuta azithamanga kwambiri ndi chakuti valavu yochepetsera mphamvu ya pampu ya mafuta imatsegulidwa mochedwa kapena osatsegulidwa, yomwe imalephera kusintha kupanikizika kwa mafuta.
3.Chifukwa chachikulu chotsegulira mochedwa kapena kusatsegula kwa valve yochepetsera mphamvu ndikuti kuyenda kwa plunger mu dzenje sikusinthika.
4. Kusiyana pakati pa plunger ndi dzenje ndi kakang'ono, kuuma kwapamwamba kumakhala kochepa, kapena dzenje la plunger liri ndi taper, ndi zina zotero, zingakhudze kutsegula kwa valve yochepetsera kupanikizika, zomwe zimapangitsa kuti mafuta azithamanga kwambiri.
5.Block mafuta ndimeyi blockage, kutsekereza fyuluta adzachititsanso mkulu mafuta.
Kuchokera ku zolakwika zomwe zimachitika pampu ya mafuta, zikhoza kuwoneka kuti zolakwika za pampu ya mafuta zimagwirizana ndi valavu yochepetsera mphamvu, choncho chidwi chapadera chiyenera kuperekedwa ku kuvomereza.
Ndizofunikira kudziwa kuti kusinthasintha kwa plunger mu valavu yochepetsera kuthamanga kumakhala ndi ubale wachindunji ndi dzenje la plunger. Povomereza, tiyenera kuyang'ana pa kuyang'ana roughness ya plunger ndi chilolezo cha dzenje kuti titsimikizire kusinthasintha kwa kayendetsedwe ka plunger mu dzenje.
