Kuputsa tsika kuti uwane zvinoshamisa: Tekinoroji yekuvhara laser inogadzira "zvombo zvakaoma kwazvo" zvemapistoni

Pakati peindasitiri yemazuva ano - masisitimu ehydraulic uye fluid - plunger, sechinhu chakakosha chinofamba, chine hunhu hwepamusoro hunotarisa zvakananga kuvimbika, kushanda zvakanaka, uye hupenyu hwebasa resisitimu yese. Kwenguva yakareba, kupera, ngura, uye kuneta zvave zviri matambudziko anotarisana nemidziyo yechinyakare yeplinders. Nhasi, tinoda kukuzivisai tekinoroji yekusimbisa pamusoro inochinja-chinja: laser cladding. Nezvakanakira zvayo zvikuru zve "micrometer-level precision" uye "metallurgical-grade bonding," tekinoroji iyi iri kuvhura chitsauko chitsva mukuvandudza mashandiro eplunger.

I. Matambudziko Echinyakare: Zvikanganiso Mukusapfeka Kwenzvimbo Inopwanyika

Plunger iyi inodzokororwa ichidzokororwa munzvimbo dzine simba guru, dzinomhanya zvakanyanya, pamwe chete nepakati pezvinhu zvakaoma, zvichiita kuti pamusoro payo parambe paine kukweshana kwakanyanya uye kurovera. Kunyangwe kana yakagadzirwa nesimbi yemhando yepamusoro, nzira dzekurapa kupisa dzechinyakare kana nzira dzekugadzira chrome dzakaoma dzichiri nemiganhu yakakura.

Kupfeka kwacho kwakatetepa (kazhinji

Kuputira nechinhu chepasi zvinongobatanidzwa nemakanika chete, zvichiita kuti delamination iwanikwe nyore nyore.

Maitiro ekuisa chrome plating ari kutarisana nematambudziko makuru ekuchengetedza nharaunda.

Mutengo wekutsiva plunger zvachose wakakwira zvikuru, uye nguva yekudzima moto inoguma nekurasikirwa kukuru.

Zvipingamupinyi izvi zvave zvipingamupinyi zvakakurumbira zvinodzivisa kushanda kwenguva refu uye kwakavimbika kwemapombi eplunger.

II. Kuchinja Kwetekinoroji: Chii chinonzi laser cladding?

Kuvhara kweLaser, kunonzi "directional metallurgy," inzira yepamusoro yekugadzira pamusoro inoshandisa matanda elaser ane simba guru kunyungudutsa ipapo ipapo zvinhu zvealloy zvine simba guru nepamusoro pechinhu chepasi, zvichibvumira kusimba nekukurumidza uye kugadzirwa kwechikamu chakasimba, chisina maburi, chisina kuputika.

Maitiro aya akafanana ne "micro-sculpture welding": Pasi pekutungamirirwa kweCNC system chaiyo, danda relaser rinofamba nenzira chaiyo yakatemerwa, "richibatanidza nekusona" nanoscale tungsten carbide, cobalt-based, kana nickel-based alloy powders panzvimbo dzakatarwa dzeplunger surface. Ukobvu hwecladding layer hunogona kugadziriswa zviri nyore mukati me 0.2 kusvika 3.0 mm, zvichiita kuti mashandiro agadziriswe nemazvo - chero kupi zvako kunoda kusimbiswa, kusimbiswa kunoshandiswa nemazvo.

III. Sei kuputira nelaser kuri "sarudzo iri nani" yekusimbisa mapuruguru?

Kuomarara kwacho kwakawedzera zvakanyanya, uye kuramba kupfeka kwawedzerawo kaviri.
Kuomarara kwelaser cladding layer kunogona kusvika HRC 60–70 (inenge HV 700–1000), inova 1.5–2 yakapetwa kupfuura simbi yemhando yepamusoro yakadzima uye 2–3 yakapetwa kupfuura chromium-plated layers yechinyakare. Mumiedzo iri mumamiriro ekushanda akaomarara, akadai seaya anowanikwa muma coal hydraulic supports nemapombi ekuboorera mafuta, avhareji yehupenyu hwebasa remapiston inowedzerwa ne300%–500%.

Kubatana kwesimbi kwakasimba zvikuru, zvichiita kuti ganda risatsvedzere zvachose.
Pakupisa kwakanyanya, jira rekuvhara nechinhu chepasi zvinosangana, zvichiita nzvimbo yekuchinja kwesimbi inenge 50–100 μm muukobvu. Simba rekubatanidza rinowanikwa nenzira iyi rinogona kudarika 80% yesimba rechinhu chepasi pachacho, nokudaro zvichigadzirisa dambudziko rekuputira.

Kugadzirisa zvinhu nemazvo uye kugadzirisa zvinhu kunogonesa kugadzira zvinhu nekuchenjera.

Kusimbisa kwenzvimbo: Kusimbisa kunongoshandiswa chete munzvimbo dzakakosha dzakadai sezvisungo zvekuvhara nezvikamu zvinotakura kumanikidzwa, nokudaro zvichichengetedza mari.

Dhizaini yeGradient: Inoita kuti gradient ishande zvakanaka iyo inofambira mberi kubva pachigadziko kusvika pamusoro, ine zvikamu zvekusimba, kuomarara, uye kuramba kupfeka.

Kudzokorodza zvikamu zvakamboshandiswa: Maoko eplunger akasakara anogadziriswa nekusunga, kudzoreredza saizi yawo yepakutanga uye kuvandudza mashandiro awo. Mutengo wekuita izvi i30% kusvika 40% chete yemutengo wekutenga zvikamu zvitsva.

Maitiro ekugadzira zvinhu zvakasvibira: kuenda kubudiriro inochengetedza magariro
Maitiro ese haana kusvibiswa nesimbi inorema uye mvura yakasviba, uye mwero wekushandiswa kwezvinhu unodarika 95%. Iyi tekinoroji yekugadzira patsva inoratidza zvechokwadi pfungwa yekugadzira zvinhu zvakasvibira.

IV. Mhinduro dzeSisitimu: Kuchinja zvakanakira zvehunyanzvi kuita kukosha kwevatengi

KuGreen Laser Tech, hatingopi chete michina yepamusoro asiwo tinoedza kupa vatengi mhinduro dzakakwana dzekusimbisa nzvimbo dzemapistoni.

Sisitimu yekugadzirira nekuchenjera: Sisitimu iyi inoshandisa musanganiswa we micro-sandblasting uye kuchenesa ne laser kuti ive nechokwadi chekuti pamusoro pe substrate pakachena zvakakwana, nokudaro ichiisa hwaro hwe cladding yemhando yepamusoro.

Chishandiso chemuchina wekuvhara jira chine mativi akawanda: Chakagadzirirwa zvinhu zvinotenderera zvakaita semapistoni, chine sisitimu yekudyisa hupfu inopindirana uye sisitimu yekuyera tembiricha panguva chaiyo, zvichiita kuti nzvimbo dzakaoma dzipfekerwe zvakaenzana.

Dhatabhesi yezvinhu izvi inopa rutsigiro nekupa mafomura ezvinhu anodarika makumi matatu ane zvitupa, akaiswa muzvikamu zvisere zvikuru, kuti agadzirire mamiriro akasiyana-siyana ekushanda akadai sekukuya kwakanyorova, kukuya kwakaoma, uye kupera kwengura.

Sisitimu yeNyanzvi yeMaitiro: Inosanganisira mazana emapakeji ekugadzirisa akagadziriswa kare ekubatanidza mapombi, achifukidza zvigadzirwa zvakasiyana-siyana - kubva kumavharuvhu akanyatsogadzirwa ane dhayamita ye20 mm kusvika kumapombi makuru ehydraulic cylinder ane dhayamita ye500 mm.

Kudzora hunhu hwese kwakavharwa: Nekubatanidza masisitimu ekutarisa online uye ekuyedza pasina internet, zvinova nechokwadi chekuti kutsauka kwekuoma kwechigadzirwa kuri ≤3%, kutsauka kwekukora kuri ≤5%, uye kushata kwepamusoro kweRa kuri ≤0.8μm.

V. Chidzidzo cheEmpirical Case: Mashandisirwo Anoitwa Nhamba Nesimba reKuchinja

Purojekiti yekugadzirisa rutsigiro rwemvura mumugodhi wemarasha

Kune boka guru remichina yemarasha yemumba, mapistoni esimbi e φ360mm akagadziriswa. Mutengo wekufukidza chikamu chimwe nechimwe waive mayuan angangoita 12,000. Nekuda kweizvozvo, hupenyu hwebasa rezvikamu izvi hwakawedzerwa kubva pamwedzi misere kusvika kumakore anopfuura matatu, zvichiita kuti mutengi akwanise kuchengetedza mari inodarika mamiriyoni mana eyuan mumari yekutsiva nekufamba kwenguva.
