Ukukhethwa kwepompo ye-servo enoxinzelelo oluphezulu sisigqibo senkqubo, asikuko ukuthengwa kwento enye. Kwiinkqubo ze-hydraulic zoshishino, ulawulo loxinzelelo, impendulo eguquguqukayo, kunye nokusebenza kakuhle kufuneka kusebenze kunye, kwaye isiseko sobugcisa sichazwa yimigangatho efana naleI-ISO 4406ucoceko lolwelo kunyeIiyunithi ze-NIST SIukuze kwenziwe umlinganiselo ohambelanayo. Kwiiprojekthi zokwenyani zokulungisa izinto, abathengi badla ngokuthelekisaisisombululo senkqubo ye-servokunye nelifaimpompo ye-vane or imoto ye-hydrauliciphakheji yokugcina umatshini usebenza ngokusetyenziswa kwamandla aphantsi kunye nokuzinza okungcono koxinzelelo.
Indlela yokukhetha ipompo ye-servo enoxinzelelo oluphezulu kwiinkqubo ze-hydraulic zemizi-mveliso
Impompo ye-servo efanelekileyo enoxinzelelo oluphezulu yileyo ihlangabezana neprofayili yomthwalo wokwenyani womatshini.
Iinkqubo ze-hydraulic zoshishino azisoloko zisebenza ngoxinzelelo olupheleleyo imini yonke, yiyo loo nto ukukhetha ipompo yeoyile ye-servo kufuneka kuqale nge-duty curve, kungekhona i-nameplate rating. Ipompo enokuhambisa i-21 MPa kwisiganeko esifutshane isenokuba lukhetho olungalunganga ukuba umatshini uchitha uninzi lomjikelo wawo kumanzi aphantsi kwaye ufuna ulawulo oluqinileyo loxinzelelo. Ngenxa yesi sizathu, iinjineli ezininzi zivavanya iphakheji epheleleyo ye-servo: ipompo, i-servo motor, i-drive, impendulo, kunye nesekethe yeoyile.
Ngokwendlela eqhelekileyo yokusebenza nge-hydraulic, amandla oxinzelelo lulwahlulo olunye kuphela lweenkcukacha. Uzinzo lokuhamba kwamanzi, ukusebenza kakuhle kwevolumu, kunye nokuziphatha kobushushu kuba yinto ebalulekileyo xa umatshini usebenzisa imijikelo ephindaphindayo. Kubathengi abatshintsha izixhobo ezindala, umbuzo obaluleke kakhulu uhlala ungowokuba ingaba iyunithi entsha ingafanelana nemvulophu yokufakela endala ngelixa iphucula impendulo kwaye inciphisa ilahleko.
Iikhrayitheriya zokukhetha ipompo ye-servo yoxinzelelo oluphezulu ezibaluleke kakhulu
Uxinzelelo, ukuhamba, ukuxinana, kunye nexesha lokuphendula kufuneka zivavanywe kunye.
Impompo ye-servo enoxinzelelo oluphezulu kufuneka ihlolwe ngokwemigangatho emihlanu esebenzayo: uxinzelelo olulinganisiweyo, uxinzelelo oluphezulu, uluhlu lokufuduka, ukunyamezela ukucoceka kweoyile, kunye nempendulo yolawulo. Ukuba isicelo sisixhobo sokucinezela i-injection molding okanye umatshini wokwenza, impompo yeoyile ye-servo kufuneka ibambe uxinzelelo ngaphandle kokuzingela, kuba uxinzelelo olungagungqiyo luguqulela kwi-flash, dimensional drift, okanye amandla okubamba angaguqukiyo.

Ukuba usetyenziso lulungelelaniswe kakuhle, kunokuba luncedo ukuphononongaUthotho lwe-SQPokanyeUthotho lwe-PV2Ruyilo lokuqonda ukuhambelana kweenyawo kunye nengqiqo yokutshintsha ngaphambi kokuba uzibophelele ekuphuculeni i-servo.
Ukutshintshwa kwempompo ye-hydraulic ye-Servo kwiinkqubo zakudala zeVickers, Denison, Yuken, Tokimec, kunye neRexroth
Ukuhambelana kudla ngokuba yinto ebalulekileyo xa kusenziwa utshintsho.
Kwimisebenzi yokulungisa, abathengi abafane baqale ukusuka ku-zero. Badla ngokufuna ipompo ye-servo enokuthatha indawo yeyunithi ye-OEM endala ngaphandle kokungasebenzi ixesha elide, umatshini ofihliweyo, okanye utshintsho lolawulo. Yingakho ukuhambelana kwinqanaba lochungechunge kubalulekile. Eyona mfuneko ixhaphakileyo yokulungisa ayikokuphucula okuqikelelweyo kodwa kukusebenza: ukugcina umatshini usebenza kakuhle ngelixa uphucula ukusebenza kakuhle, ingxolo, kunye nempendulo.
Kwizixhobo ezindala, ukulingana kwekhathalogu kufuneka kuhlolwe ngokweeleya ezintathu: ukusebenza kwe-hydraulic, ujongano lwe-mechanical, kunye nokuhlanganiswa kolawulo. Impompo yeoyile ye-servo inokuba ngcono ngobuchwephesha kodwa isahluleke kwintsimi ukuba isitshixo se-shaft, i-flange, i-port orientation, okanye ujongano lwe-wiring ayilunganga. Kumsebenzi wokutshintsha, kulapho i-matrix yemveliso ehleliweyo iba luncedo khona.
- Qinisekisa uthotho lokuqala kunye nobukhulu befreyimu ngaphambi kokukhetha enye.
- Ukuhanjiswa komtya, ukujikeleza, uhlobo lomngxuma, kunye nobuso bokuxhoma.

Xa injongo ikukuhanjiswa ngokukhawuleza kunye nenkxaso endala, abathengi badla ngokuthelekisa iintsapho ezininzi zemveliso ngaxeshanye, kubandakanyaUthotho lwe-Vukhetho lokuqhubeka kwenkqubo kunyeUthotho lwe-V10ukhetho lokufaka indawo ebanzi.
Indlela imigangatho ye-ISO kunye nococeko lolwelo oluchaphazela ngayo ubomi bepompo ye-servo yoxinzelelo oluphezulu
Ioyile ecocekileyo yenye yezona zinto zibalaseleyo ezibonisa ukuthembeka kwepompo ye-servo.
Iinkqubo zeServo zinovelwano kakhulu kungcoliseko kuba iindawo ezivulekileyo eziqinileyo kunye nee-loops zokuphendula ngokukhawuleza azivumeli kangako iinxalenye ezigugileyo.I-ISO 4406isetyenziswa kakhulu ukuchaza amanqanaba okungcoliswa kolwelo lwe-hydraulic, kwaye ulawulo olungcono lokungcoliswa luxhasa ngokuthe ngqo ubomi obude bezinto. Kubathengi, oku kuthetha ukuba ukuhluza yinxalenye yokukhetha ipompo, kungekhona into ecingelwa emva koko.
Ngokwenyani, ulawulo longcoliseko kufuneka luchazwe ecaleni kwepompo. Ukuba umatshini usebenza kwindawo erhabaxa okanye esebenza kakhulu, umlinganiselo we-filter beta, ukuphefumla kwereservoir, kunye nexesha lokugcinwa kunokubaluleka njengepompo ngokwayo. Kumaqela asentsimini, imeko yeoyile ezinzileyo inciphisa ukuguguleka kwekhatriji, ukushukuma koxinzelelo, kunye nexesha lokungasebenzi kakuhle.
| Into yococeko | Kutheni kubalulekile | Inqaku lokukhetha |
|---|---|---|
| Ungcoliseko lwamasuntswana | Ikhawulezisa ukuguguleka kwepompo kunye neevalvu | Cacisa ukuhluza kwinqanaba lenkqubo |
