Gore rapfuura, bhazi remagetsi rakangoerekana rakundikana kushandisa brake assist pachikamu chinodzika cheYunnan-Guizhou Plateau. Ongororo yakawana kuti chikonzero chikuru chaive kutadza kwevacuum controller imwe chete kwakaita kuti vacuum pomp imire, uye tangi diki revacuum rakanga risina kuchengetwa kwesimba kwakakwana, izvo zvakapotsa zvakonzera tsaona huru1. Nyaya iyi yakaratidza njodzi dzekugadzira masisitimu echinyakare evacuum assist uye yakaitawo kuti indasitiri itange kuongorora zvakare basa guru rema micro DC vacuum pumps mumasisitimu emagetsi emotokari.

Sei mota dzemagetsi dzichifanira kushandisa mapombi evacuum cleaner madiki?

Mumotokari dzekare dzinoshandisa mafuta, injini intake manifold inogadzira kumanikidzwa kusina kunaka, zvichipa mukana wekuti brake assist system ishande zvakanaka. Zvisinei, mota dzemagetsi hadzina injini, uye kana dzisina injini, brake pedal inorema zvakanyanya - simba rebraking rekushandisa manual braking chete harina kukwana zvinodiwa zvekuchengetedza.

Panguva ino, apombi yekuchenesa yeDC dikip inova mhinduro chete:

Kutyaira kwemagetsi: shandisa zvakananga magetsi emotokari e12V/24V, tyaira piston kana diaphragm kuti ufambe nekumhanya kwakanyanya mumota, uye bvisa vacuum3 nesimba;

Mhinduro pfupi:Semuenzaniso, HD-PC3025N inogona kuunza kumanikidzwa kusina kunaka kwe -70kPa mukati mesekondi imwe chete kuti ikwanise kuzadzisa zvinodiwa zvekumisa mabhureki panguva yekukurumidza3;

Kupa simba kwakazvimirira:haigumiri pakushanda kweinjini, inogona kushanda kunyangwe mota yacho isina kumira zvakanaka

Mapombi evacuum cleaner anokunda sei zvipingamupinyi uye anozadzisa sei zvinodiwa nemotokari?

1. Zviratidzo zvekushanda: kuenzana pakati pe vacuum nekuyerera kwemvura

Dambudziko rePlateau:Pakukwirira kwemamita 3,000, kumanikidzwa kwemhepo kunoderera kusvika pa70kPa (101kPa panzvimbo isina chinhu). Kana vacuum yepombi iri -50kPa chete, kumanikidzwa kwesimba remagetsi kunoora kusvika pa -20kPa, zvichikonzera kushomeka kwakanyanya kwekubatsira mabhureki. Saka, zvakakosha kusarudza modhi ine vacuum ye ≥-70kPa (yakadai sePC3025N) kuti usiye mukana wekuchengetedza.

Kuderedza kuyerera kwemvura:Papombi ine kuyerera kwe25L/min, kuyerera chaiko kunogona kuderera kusvika 15L/min mushure mekubatanidza pombi yemita imwe + magokora maviri. Munguva yekubhureka nguva dzose (senge kudzika kwenguva refu), kana kuyerera kusina kukwana uye kumanikidzwa kwetangi revacuum kusingagone kuchengetwa, alarm yebhureki ichatanga.

 

2.Kuvimbika: Inishuwarenzi mbiri yekudzivirira kugara kwenguva refu uye kutadza

Bvunzo rekutsungirira kwemaawa 1500:Ruhaizhibo iEVP Pro yakagadziriswa nemarotor egraphite, uye hupenyu hwayo hunopfuura hwevanokwikwidza pasi rose

Danho rechipiri: Kuenzanisa vacuum & flow

Tafura yekutarisa nekukurumidza (tichitora mienzaniso yakajairika yePincheng semuenzaniso)

 

Dhizaini yemutongi maviri isina kudzorwa:Sisitimu itsva inoshandisa ma vacuum controller maviri akafanana. Kana imwe ikakundikana, imwe inogona kudzora pombi kuti ishande, zvichibvisa kukanganisa kwepoinzi imwe chete

Nzira yekuderedza mutoro ine hungwaru:Kana vacuum leak (kubuda kwemhepo isina kujairika) yaonekwa, inochinja yega kuenda ku intermittent operation mode kudzivirira mota kuti isatsve

Kuchinjika kwezvakatipoteredza: kubva pakutonhora zvakanyanya kusvika pakunyorova kwakanyanya

Kushivirira mhute yemvura:Sisitimu yemabhureki inogona kufema mhepo ine hunyoro, uye mapombi akajairwa anogona kuita ngura. Zvisinei, pombi yePC mini vacuum inobvumira kuti medium ive "yakapfuma muutsi hwemvura" uye inoshandisa fluororubber seals mukati.

-30℃ kutanga kutonhora:Mapombi emota asina mabhurashi (akadai seVML series) anogona kupindura nekukurumidza kana tembiricha yakaderera, achidzivirira njodzi yekuoma kwemasisitimu echinyakare ehydraulic

 

3. Matambudziko Echokwadi: Zvipingamupinyi uye Mhinduro dzeMicromuchina wekuchenesapombi

Kunyangwe tekinoroji iyi yakakura, mapombi madiki achiri kutarisana nematambudziko makuru matatu ari kushandiswa:

Kushandiswa kwesimba uye kusawirirana kweNVH (ruzha nekudengenyeka)

Mapombi anoyerera zvakanyanya anowanzova nesimba rinodarika 40W, uye kushanda nguva dzose kunotora simba rakawanda (rinoverengera inenge 0.5% yehuwandu hwemotokari yemagetsi). Panguva imwe chete, ruzha rwemotokari runogona kutumirwa kucockpit. Mhinduro:

Mota isina brushless + variable frequency control: Semuenzaniso, VML series inoderedza kushandiswa kwesimba risina kushanda nemutemo wekumhanya7;

Chifukidziro chisingapindi ruzha + kuderedza kudedera kwepombi: mhinduro yakajairika kune maOEM.

Njodzi yekupisa zvakanyanya munzvimbo dzakadzika uye dzinodonhedza mvura

Munzvimbo dzakadzika kana kuti kana chisimbiso chakundikana, pombi inogona kupisa zvakanyanya nekuda kwekushanda kwenguva refu. Mutongi mutsva anomisa pombi nekuchenjera kuburikidza nekutarisa kumanikidzwa kwemhepo:

Kana kudonha kwesimba remhepo kuri pasi pe8mbar/s mukati memasekonzi gumi ekushanda, sisitimu yacho inoonekwa seyakajairika uye pombi inomiswa ipapo ipapo;

Kana gradient isina kujairika (kubuda kwemvura), ichapinda mu "work 15 seconds + stop 10 seconds" protection cycle4.

Mutambo wenzvimbo uye mutengo

Mapombi makuru (akadai sePC3025N) anorema 1kg uye anotora nzvimbo yechassis. Kunyangwe mhinduro ye dual controller + large-volume vacuum tank ichivandudza kuvimbika, mutengo unowedzera neinenge 30%15. Mafambiro eindasitiri iyi dhizaini yakabatana: Haizhibo inoisa controller mumuviri wepombi kuderedza waya dzemagetsi uye ma interfaces6.

 

Kutungamira mune ramangwana: kwete kungova "basa rekutsigira" chete

Nekuvandudzwa kwekutyaira kwakangwara, mabasa emapombi evacuum madiki ari kuwedzera:

Backup isingawanzoitiki yekutyaira wega pamusoro pedanho reL3:Kana brake remagetsi rehydraulic rikakundikana, sisitimu yekusimbisa vacuum inotora basa rekuchengetedza maginicha7;

Mhepo inomiswa inoshanda:Mamwe mamodheru anoshandisa pombi imwechete ye vacuum kupa simba muchitubu chemhepo, zvichiita kuti "pombi imwe chete ishandiswe kakawanda"6;

Kutenderera kwehydrogen mumotokari yemafuta ehydrogen:Mapombi madiki anodzivirira ngura anoshandiswa mu hydrogen circulation system kuvandudza kushandiswa kwemafuta3.

 

Mhedziso: Zvikamu zvakakosha, asi kugadzirisa kwemazinga ehurongwa kunodiwa

Mapombi evacuum eMicro DC anonyatso zadzisa zvinodiwa zvemagetsi zvemotokari dzemazuva ano, asi anofanira "kusarudzwa zvichienderana nezviratidzo":

Mota dzemhuri:Chikamu chePC3025N (-70kPa, 25L/min) chine controller imwe chete + tangi re vacuum re8L chakakwana8;

Mota dzekutengeserana/mhando dzemakomo: dzinoda mapombi ari pamusoro pe -80kPa + ma controller maviri + matangi makuru e 15L e vacuum, uye gadzirisa pressure gradient monitoring14;

Mota dzemangwana dzakangwara:Pombi dzemota dzisina mabhurashi (dzakadai seVML) dzichava dzakakurumbira, tichifunga nezvekushanda zvakanaka, runyararo uye kutonga kwakangwara67.

Sekubvumirana kwemainjiniya: Kunyangwe kushanda kwepombi imwe chete kwakasimba sei, haina kunaka sekubatana kwesystem kwe "pombi-tank-controller-sensor". Pakusarudza, haufanirwe kungotarisa chete ma parameter epombi, asiwo kutarisa kugona kwayo mutoro uye mashandiro emhinduro yekukanganisa musystem yese yemotokari - mushure mezvose, ma milliseconds pakati pemabhureki anosarudza muganhu wekuchengetedza hupenyu.

Shenzhen Pincheng Motorane makore mazhinji eruzivo muR&D uye kugadzirwa kwepombi dzevacuum cleaner, uye yapasa chitupa chemotokari cheIATF 16949, icho chinogona kupa mhinduro dzakanaka dzekugadzira zvikamu zvemotokari.
