Umwaka ushize, bisi y'amashanyarazi yahuye n'ikibazo gitunguranye cy'ubufasha bwo gufunga feri ku gice cyo kumanuka gikomeza kumanuka cya Yunnan-Guizhou Plateau. Iperereza ryagaragaje ko impamvu nyamukuru ari ukunanirwa gupima amashanyarazi byatumye pompe y'amashanyarazi ihagarara, kandi ikigega gito cy'amashanyarazi cyari gifite ubushobozi bwo kubika ingufu buhagije, byaje guteza impanuka ikomeye1. Uru rubanza rwagaragaje ingaruka mbi z'imiterere ya sisitemu zisanzwe zo gufasha amashanyarazi ndetse bituma inganda zitangira kongera gusuzuma uruhare rw'ingenzi rwa pompe z'amashanyarazi za micro DC mu sisitemu zifasha amashanyarazi mu modoka.

Kuki imodoka zikoresha amashanyarazi zigomba kwishingikiriza ku pompe nto zikoresha amashanyarazi?

Mu modoka zisanzwe zikoresha lisansi, moteri ifata moteri itera umuvuduko mubi, bigatuma habaho uburyo bwo gufasha feri4. Ariko, imodoka zikoresha amashanyarazi ntizigira moteri, kandi iyo zidafite aho zikoresha feri, pedali ya feri iraremereye cyane - imbaraga zo gufunga feri zonyine ntizuzuza ibisabwa mu mutekano.

Muri iki gihe, haripomo y'icyuma gisukura umwuka (vacuum pum) ya micro DCp iba igisubizo cyonyine:

Imodoka y'amashanyarazi: koresha neza amashanyarazi ya 12V/24V y'imodoka, shyira piston cyangwa diaphragm mu modoka kugira ngo binyure muri moteri ku muvuduko mwinshi, kandi ukuremo imashini ikoresha umwuka mubi3;

Igisubizo cyihuse:Urugero, HD-PC3025N ishobora gushyiraho umuvuduko mubi wa -70kPa mu isegonda 1 kugira ngo ihuze n'ibikenewe mu gihe cyihutirwa cyo gufunga feri3;

Ingufu zitangwa mu buryo bwigenga:idashingiye ku mikorere ya moteri, ishobora gukora nubwo imodoka yaba ihagaze

Ni gute pompe nto zikoresha amashanyarazi zitsinda inzitizi kandi zigakurikiza ibisabwa bikomeye by'imodoka?

1. Ibipimo by'imikorere: kuringaniza hagati y'ingufu n'amazi

Irushanwa ryo mu gace ka Plateau:Ku butumburuke bwa metero 3.000, umuvuduko w'ikirere ugabanuka ukagera kuri 70kPa (101kPa ku kibaya). Niba icyuma gishyuha cy'ipompo ari -50kPa gusa, umuvuduko nyawo ugaragara neza uzagabanuka ukagera kuri -20kPa, bigatuma habura ubufasha bukomeye bwo gufunga feri. Kubwibyo, ni ngombwa guhitamo icyitegererezo gifite icyuma gishyuha cy'imvura cya ≥-70kPa (nka PC3025N) kugira ngo habeho urwego rw'umutekano.

Kugabanya umuvuduko w'amazi:Ku ipompe ifite umuvuduko wa litiro 25 ku munota, umuvuduko nyawo ushobora kugabanuka ukagera kuri litiro 15 ku munota nyuma yo guhuza umuyoboro wa metero 1 + inkokora 2. Mu gihe cyo gufunga feri (nk'aho kumanuka umusozi muremure), niba umuvuduko udahagije kandi umuvuduko wa tanki idafite umwuka uhagije ntushobora gukomeza, inzogera ya feri izatangira gukoreshwa.

 

2.Kwizerwa: Ubwishingizi bubiri bwo kuramba no gukumira gutsindwa

Ikizamini cyo kwihangana cy'amasaha 1500:Ruhaizhibo iEVP Pro yatunganyijwe hakoreshejwe rotors za grafiti, kandi igihe cyo kubaho cyayo kirenze igihe cy'abanywanyi mpuzamahanga.

Intambwe ya 2: Huza imikorere y'ingufu n'imiyoboro y'amazi

Imbonerahamwe y'igenzura ryihuse (dufashe urugero rwa Pincheng common models)

 

Igishushanyo mbonera cy’ibikoresho bibiri bigenzura:Sisitemu nshya ikoresha uburyo bubiri bwo kugenzura imashini zikoresha umwuka. Iyo imwe inaniwe, indi ishobora kugenzura ipompo kugira ngo ikore, bigakuraho ikibazo cy'ingingo imwe

Ingamba zo kugabanya umutwaro mu buryo bw'ubwenge:Iyo hagaragaye ko hari aho umwuka uva mu cyuma (umuvuduko udasanzwe), ihita ihindura uburyo bwo gukora buri gihe kugira ngo irinde moteri kuzimya umuriro.

Guhuza ibidukikije: kuva ku bukonje bukabije kugeza ku bushyuhe bwinshi

Kwihanganira umwuka w'amazi:Sisitemu yo gufunga feri ishobora guhumeka umwuka utose, kandi pompe zisanzwe zishobora kwangirika. Ariko, pompe nto ya PC mini vacuum yemerera icyuma kuba "gikungahaye ku mwuka w'amazi" kandi gikoresha imitako ya fluororubber imbere.

Gutangira gukonjesha -30℃:Pompe za moteri zitagira uburoso (nk'uruhererekane rwa VML) zishobora kongera gukora vuba mu bushyuhe buke, zikirinda ibyago byo gukomera kwa sisitemu zisanzwe za hydraulic

 

3. Imbogamizi Nyazo: Imbogamizi n'Ibisubizo bya Microimashini ikoresha umwuka udafite umwukapompe

Nubwo ikoranabuhanga rimaze igihe kinini, pompe nto ziracyahura n'ibibazo bitatu bikomeye mu ikoreshwa ryazo:

Ikoreshwa ry'ingufu n'amakimbirane ya NVH (urusaku n'ihindagurika ry'ikirere)

Pompe zikoresha amazi menshi akenshi ziba zifite imbaraga zirenga 40W, kandi imikorere ihoraho itwara ingufu nyinshi (zingana na 0.5% by'ingano y'imodoka zikoresha amashanyarazi). Muri icyo gihe, urusaku rwa moteri rushobora koherezwa mu cyumba cy'abashinzwe umutekano. Ibisubizo:

Moteri idafite uburoso + igenzura ry’impinduka zihindagurika: Urugero, uruhererekane rwa VML rugabanya ikoreshwa ry’ingufu zidakora hakoreshejwe uburyo bwo kugenzura umuvuduko7;

Igipfukisho kidakoresha amajwi + kugabanya umuvuduko w'imiyoboro: igisubizo gisanzwe kuri OEMs.

Ingaruka z'ubushyuhe bukabije mu bice bito n'ibitonyanga

Mu bice by'ubutaka cyangwa iyo ikiziriko cyabuze, pompe ishobora gushyuha cyane bitewe n'igihe kirekire ikora. Umugenzuzi mushya uhagarika pompe neza binyuze mu kugenzura umuvuduko w'amashanyarazi:

Iyo umuvuduko ugabanuka uri munsi ya 8mbar/s mu masegonda 10 uhereye igihe utangiye gukora, sisitemu ifatwa nk'aho isanzwe kandi pompe igahita ihagarara;

Iyo imiterere y'amazi idasanzwe (isohoka), izinjira mu "kazi amasegonda 15 + guhagarara amasegonda 10"4.

Umukino w'umwanya n'ikiguzi

Pompe nini zikoresha amazi menshi (nka PC3025N) zipima kilogarama 1 kandi zifata umwanya wa chassis. Nubwo uburyo bwo kugenzura bubiri hamwe n'uburyo bwo gusohora amazi menshi butuma habaho ubwizerwe, ikiguzi cyiyongeraho hafi 30%15. Icyerekezo cy'inganda ni igishushanyo mbonera cyuzuye: Haizhibo ishyira icyuma gikoresha amazi mu gice cy'ipompe kugira ngo igabanye imigozi n'imirongo ihuza insinga6.

 

Icyerekezo cy'ejo hazaza: si "uruhare rw'inyongera" gusa

Bitewe no kuvugurura uburyo bwo gutwara ibintu mu buryo bw’ubwenge, imikorere ya pompe nto zikoresha amashanyarazi irimo kwaguka:

Ingoboka idahagije yo gutwara imodoka yigenga hejuru y'urwego rwa L3:Iyo feri y'amashanyarazi inaniwe, sisitemu yo kongera imbaraga ifata umwanya nk'iy'ubufasha bwa mekanike7;

Ingufu zitanga umwuka wo guhagarika:Hari ubwoko bumwe bukoresha pompe imwe y'umwuka mu gutanga ingufu ku isoko ry'umwuka, bigatuma "pompe imwe ikoreshwa kenshi"6;

Izenguruka rya hydrogen mu modoka ikoresha lisansi ya hydrogen:Pompe nto zirwanya ingese zikoreshwa muri sisitemu yo gutemberamo hifashishijwe hydrogen kugira ngo zirusheho gukoresha lisansi3.

 

Umwanzuro: Ibice by'ingenzi, ariko kunoza urwego rwa sisitemu birakenewe

Pompe za Micro DC zikoresha vacuum cleaner zihuye neza n'ibikenewe mu bufasha bw'amashanyarazi bw'imodoka zigezweho zikoresha amashanyarazi, ariko zigomba "gutoranywa hakurikijwe ibimenyetso":

Imodoka z'umuryango:Urwego rwa PC3025N (-70kPa, 25L/min) rufite agakoresho kamwe ko kugenzura + tanki ya 8L yo gusukura irahagije8;

Ibinyabiziga by'ubucuruzi/ubwoko bw'ibinyabiziga byo mu misozi miremire: bisaba ipompo zirengeje -80kPa + ibikoresho bibiri byo kugenzura + tanki nini za 15L, kandi bigashyiraho uburyo bwo kugenzura umuvuduko w'amashanyarazi14;

Imodoka zigezweho mu gihe kizaza:Pompe za moteri zitagira uburoso (nka VML) zizaba ingenzi, hashingiwe ku mikorere myiza, ituze n'ubuyobozi bw'ubwenge67.

Nk’uko injeniyeri zibyemeza: Uko imikorere ya pompe imwe yaba ikomeye kose, ntabwo ari nziza nk’uko sisitemu ihuza "pompe-tank-controller-sensor". Mu guhitamo, ntugomba kureba gusa ibipimo bya pompe, ahubwo ugomba no kugenzura ubushobozi bwayo bwo gutwara n’uburyo bwo gusubiza amakosa muri sisitemu yose y’imodoka - nyuma ya byose, milisegonda hagati ya feri ni zo zigena igihe cy’umutekano.

Shenzhen Pincheng Motorafite uburambe bw'imyaka myinshi mu bushakashatsi no mu ikorwa ryapompe ntoya zo mu bwoko bwa "vacuum", kandi yatsinze icyemezo cya IATF 16949 cy’imodoka, gishobora gutanga ibisubizo byiza byo gukora ibice by’imodoka.
