Chithunzi cha Priciple cha Pampu ya Magiya
ThePampu ya hydraulic ya VGndi pampu yamkati yolumikizira kumbuyo yokhala ndikusamutsidwa kosasinthikaKapangidwe kake koyambira ndi: chivundikiro chakutsogolo chachikulu (1), thupi la pampu (2), chivundikiro chakumbuyo (3), shaft ya giya lakunja (4), mphete yamkati ya giya (5), chotengera chotsetsereka (6), mbale yogawa mafuta (7), ndi ndodo yoyikira (8), ndipo imakhala ndi bolodi laling'ono (9), bolodi lalikulu la crescent (10) ndi ndodo yotsekera (11).
Njira yoyamwitsa ndi kutayira
Shaft yakunja ya giya (4) yomwe imayikidwa motsatira mphamvu yamadzimadzi imayendetsa mphete yamkati ya giya (5) molunjika komwe yawonetsedwa. Dzazani mafuta kudzera m'malo otseguka a dzino m'malo opopera mafuta. Mafutawo amasamutsidwa kuchokera kudera lopopera mafuta (S) kupita kudera lopanikizika (P) kudzera m'mbali mwa msewu pakati pa shaft yakunja ya giya ndi mphete yapakati pa giya. Zotsatira zake, mafutawo amatulutsidwa kuchokera ku malo otsekedwa a dzino ndikuperekedwa ku doko lamafuta opanikizika (P). Malo opopera mafuta ndi malo otulutsira mafuta amalekanitsidwa ndi radial compensation element (9 mpaka 11) ndi maukonde a giya pakati pa giya yamkati yamkati ndi giya yakunja.
Kulipira kwa Axial
Chipinda chotulutsira mafuta m'dera lopanikizika chimatsekedwa ndi mbale yogawa ya tge iuk (7). Chipinda chotulutsira mafuta chimayang'ana kutali ndi malo otulutsira mafuta ndipo mbali imodzi kumbuyo kwake imakakamizidwa ndi mphamvu yoperekedwa (12). Malo opanikizika awa amapangitsa mbale yotulutsira mafuta ndi malo otulutsira mafuta kufika pamlingo woyenera, chifukwa cha kutseka koyenera kumachitika ndi kutayika kochepa kwa makina.
Kubwezera kwa radial
Chinthu cholumikizira ma radial chimaphatikizapo mbale yaing'ono ya crescent (9), mbale yayikulu ya crescent (10) ndi ndodo yotsekera (11). Mbale yayikulu ya crescent (10) yomwe ili pamwamba pa nsonga ya booth ya shaft yakunja ya gear, mbale yaing'ono ya crescent (9) imalumikizidwa kwambiri ndi nsonga yozungulira ya nsonga ya dzino la mphete yamkati ya gear, ndipo ndodo yoyikira imagwiritsidwa ntchito kuletsa kuyenda kwa mbale ya crescent munjira yozungulira.
Mwanjira imeneyi, dera lopanikizika limatha kulekanitsidwa ndi dera loyamwitsa pogwiritsa ntchito njira yodziyimira yokha. Ichi ndi chofunikira kuti pakhale mphamvu zambiri zogwiritsa ntchito nthawi zonse panthawi yonse yogwira ntchito.
Kudula mano
Kudula mano komwe kuli ndi mbali zosasinthika kumakhala ndi utali wautali wa maukonde kuti madzi aziyenda pang'onopang'ono komanso kuti kuthamanga kwa mpweya kusamayende bwino, motero kumatsimikizira kuti phokoso likugwira ntchito pang'ono.

Kugwiritsa ntchito
Itha kugwiritsidwa ntchito kwambiri m'makampani, monga makina apulasitiki, makina a nsapato, makina oponyera ndi forklift ndi mafakitale ena, makamaka makina osungira mphamvu a servo variable frequency drive.
Mfundo zofunika kuziganizira
1. Kuyika pampu yamafuta
- Momwe zingathere, cholumikizira chosinthasintha chimagwiritsidwa ntchito polumikiza pakati pa shaft ya pampu ndi shaft ya mota kuti tipewe kupindika kwa mphindi kapena kugwedezeka kwa axial. Cholakwika chachikulu chovomerezeka cha coaxiality pakati pa shaft ya pampu ndi shaft ya mota ndi 0.15mm.
2. Kulumikiza malo olowera ndi otulutsira
- Sankhani m'mimba mwake wa payipi malinga ndi doko la mafuta la pampu yamafuta (liwiro labwino kwambiri lolowera ndi 0.6-1.2m/s);
- Miyeso ya kapangidwe ka chingwe chokokera madzi iyenera kutsatira mphamvu yolowera madzi (mtengo wake wonse ndi 0.8bar mpaka 2bar), ndipo iyenera kupewa kupinda chingwe chokokera madzi ndi kuphatikiza kwa machubu angapo okokera madzi pampu;
- Ngati flita yoyamwa mafuta ikugwiritsidwa ntchito, tikulimbikitsa kuti fyuluta yoyamwa mafuta isankhidwe malinga ndi kuchuluka kwa madzi omwe amatuluka pa pampu yamafuta, kuchulukitsidwa ndi coefficient ya nthawi 2-3, ndipo kulondola konse kwa kusefa ndi 50-180um. Ziyenera kutsimikiziridwa kuti ngakhale fyulutayo yadetsedwa, sidzapitirira mphamvu yocheperako yolowera mu makina;
- Kuzama kwa madzi mu chubu choyamwa madzi chosankhidwa kuyenera kukhala kozama momwe zingathere. Mafunde a Eddy sayenera kupangidwa ngakhale pamlingo wapamwamba kwambiri, apo ayi kudzakhala chiopsezo choyamwa ndi kutulutsidwa kwa mpweya.
- Pakupanga chitoliro chokoka mafuta, cholowera mafuta sichikulimbikitsidwa kuti chiyikidwe moyimirira pansi. Ngati thanki yamafuta ili pansi pa pampu yamafuta, cholowera mafuta chiyenera kukhala mmwamba kapena mbali zonse ziwiri zopingasa.
3. Kuphatikiza kwa pampu
- Mukaphatikiza mapampu, ndikofunikira kuonetsetsa kuti gawo lililonse likugwirizana ndi tsiku lovomerezeka la mitundu yoyenera ya mapampu;
- Njira yozungulira mapampu onse ophatikizidwa iyenera kukhala yofanana;
- Mapampu okhala ndi mphamvu yayikulu, kusinthasintha kosinthika kapena katundu wogwiritsidwa ntchito ayenera kuperekedwa ngati gawo loyamba la pampu yophatikizana;
- Wokonza polojekiti ayenera kuyang'anitsitsa mphamvu ya shaft drive torque pa ntchito zosiyanasiyana.
Mphamvu yovomerezeka yoposa mphamvu zonse (Nm)
Mphamvu yonse ya pampu yophatikizidwa siyenera kupitirira mphamvu yayikulu yoyendetsera.
Kupuma mophatikizana sikuloledwa.
Kapangidwe ka shaft ya pampu yakumbuyo kayenera kukhala "R" (spline).
4. Ntchito yoyamba
- Onetsetsani ngati dongosolo la hydraulic layikidwa bwino ndikulumikizidwa poyambira koyamba;
- Musanayambe ntchito, muyenera kudutsa mu chubu chokoka kapena flowline kuti mudzaze mkati ndi pampu yamafuta ya hydrailic, valavu yochepetsera mafuta, kutsegula makinawo pansi pa ma motors osanyamula katundu, kusunga pampu yochepetsera mafuta okwanira, ndikutulutsa mpweya mu mapaipi (mafuta sayikidwa, monga momwe makinawo angagwiritsire ntchito cholumikizira chotulutsira mpweya, njira zina, kuti mpweya wotuluka utuluke. Ngati thovu silikuwonekanso mumafuta otayikira, gawo lomasulidwa liyenera kutsekedwa malinga ndi mphamvu yomwe yatchulidwa. Dziwani: mukagwiritsa ntchito njira iyi, iyenera kutsekedwa pansi pa mphamvu yotsika ndikuwonetsetsa kuti kuthamanga sikukwera.)
- Sizingathe kuyamba kulongedza, apo ayi zidzawononga mkati mwa pampu yamafuta.
- Pambuyo pochita madontho mobwerezabwereza, phokoso loyamwa lidzasowa. Ngati phokoso losakaniza mpweya silidzatha pambuyo pochita madontho mobwerezabwereza kwa kangapo, payenera kukhala kutuluka kwa mpweya mupaipi kumbali yolowera.
5. Kukonza
- Pofuna kukonza bwino ntchito yokweza mafuta pampope, kugwedezeka kosazolowereka, phokoso, kutentha kwa mafuta, momwe mafuta alili mu dongosolo la hydraulic, ngati pali thovu mu thanki komanso ngati pali kutuluka kwa madzi ndi mavuto ena ziyenera kufufuzidwa nthawi zonse ndikusamalidwa nthawi yake;
- Mapampu onse amafuta adutsa mayeso a magwiridwe antchito asanachoke mufakitale. Kampani iliyonse kapena munthu aliyense sayenera kusokoneza, kusonkhanitsanso kapena kusintha mapampu amafuta popanda chilolezo cha kampani. Ngati asokoneza, kusonkhanitsanso kapena kusintha mapampu amafuta popanda chilolezo cha kampani, sizili mkati mwa lipoti la kukonza la kampaniyo ndipo kampaniyo sidzatenga udindo uliwonse.
