Malinga ndi zofunikira ndi zikhalidwe zogwirira ntchito, sankhani bwino mtundu wa silinda. Ngati silinda ikufunika kuti ifike kumapeto kwa sitiroko popanda kukhudzidwa ndi phokoso lamphamvu, silinda yachitetezo iyenera kusankhidwa; ngati pakufunika kulemera kwake, silinda yowala iyenera kusankhidwa; ngati pakufunika kukhala ndi malo ochepetsetsa oyikapo ndi kukwapula kochepa, silinda yopyapyala ikhoza kusankhidwa; ngati pali katundu wotsatira, silinda yokhala ndi ndodo yotsogolera ikhoza kusankhidwa; Ngati kulondola kwa braking ndikwapamwamba, silinda yotsekera iyenera kusankhidwa; ngati ndodo ya pisitoni siloledwa kuzungulira, silinda yokhala ndi ntchito yosasinthasintha ya ndodo ingasankhidwe; m'malo otentha kwambiri, silinda yosagwira kutentha iyenera kusankhidwa; m'malo owononga, silinda yolimbana ndi dzimbiri iyenera kusankhidwa. M'malo ovuta monga fumbi, ndikofunikira kukhazikitsa chivundikiro chafumbi kumapeto kwa ndodo ya pistoni. Ngati palibe kuipitsa komwe kumafunikira, ndikofunikira kusankha masilinda amafuta opanda mafuta kapena opanda mafuta, ndi zina zambiri.

2. Fomu yoyika

Zimatengera zinthu monga malo oyika ndi cholinga chogwiritsa ntchito. Kawirikawiri, silinda yokhazikika imagwiritsidwa ntchito. Pamene kuli kofunikira kusinthasintha mosalekeza ndi makina ogwirira ntchito (monga lathes, grinders, etc.), silinda yozungulira iyenera kusankhidwa. Pamene ndodo ya pistoni ikufunika kuti ipange arc swing kuwonjezera pakuyenda kwa mzere, pivot pini silinda imasankhidwa. Pakakhala zofunikira zapadera, silinda yapadera yofananira iyenera kusankhidwa. Nkhani ya anthu "Mechanical Engineering Literature", malo opangira mafuta a injiniya!

3. Kukula kwa mphamvu

Ndiko kuti, kusankha anaboola awiri. Tsimikizirani kukankhira ndi kukoka mphamvu yotulutsa ndi silinda molingana ndi mphamvu ya katundu. Kawirikawiri, mphamvu ya silinda yofunikira ndi chikhalidwe cha kulingalira kwa katundu wakunja imagwiritsidwa ntchito, ndipo mitengo yolemetsa yosiyana imasankhidwa molingana ndi liwiro losiyana, kotero kuti mphamvu yotulutsa ya silinda imakhala ndi malire pang'ono. Ngati m'mimba mwake ya silinda ndi yaying'ono kwambiri, mphamvu yotulutsa sikwanira, koma ngati m'mimba mwake ya silinda ndi yayikulu kwambiri, zidazo zidzakhala zochulukirapo, mtengo wake udzawonjezeka, ndipo kugwiritsa ntchito mpweya kudzawonjezeka, zomwe zidzawononga mphamvu. Popanga mawonekedwe, njira yowonjezera iyenera kugwiritsidwa ntchito momwe mungathere kuti muchepetse kukula kwa silinda.

4. Piston sitiroko

Zimakhudzana ndi nthawi yogwiritsira ntchito komanso kugunda kwa makinawo, koma nthawi zambiri sitiroko yonse siyimasankhidwa kuti pisitoni isagundane ndi mutu wa silinda. Ngati agwiritsidwa ntchito pa clamping limagwirira, etc., malire a 10-20mm ayenera kuonjezedwa malinga ndi sitiroko zofunika kuwerengera.

5. Kuthamanga kwa pisitoni

Zimatengera kuchuluka kwa mpweya woponderezedwa wa silinda, kukula kwa madoko olowera ndi utsi wa silinda ndi m'mimba mwake mkati mwa ngalande. Zimafunika kutenga mtengo waukulu wothamanga kwambiri. Kuthamanga kwa silinda nthawi zambiri kumakhala 50-800mm /s. Kwa ma cylinders othamanga kwambiri, chitoliro cholowetsa chokhala ndi mainchesi amkati chiyenera kusankhidwa; pakusintha kwa katundu, kuti mupeze liwiro loyenda pang'onopang'ono komanso lokhazikika, chipangizo chowongolera kapena silinda yamadzimadzi yamadzimadzi ingagwiritsidwe ntchito, zomwe zimakhala zosavuta kukwaniritsa liwiro. Posankha valavu ya throttle kuti muwongolere liwiro la silinda, chisamaliro chiyenera kuperekedwa kwa: pamene silinda yokhazikika yokhazikika ikukankhira katundu, tikulimbikitsidwa kugwiritsa ntchito mpweya wotulutsa mpweya kuti musinthe liwiro; pamene silinda yoikidwa yoyimilira imakweza katunduyo, tikulimbikitsidwa kugwiritsa ntchito mpweya wolowetsa mpweya kuti musinthe liwiro; kusuntha kumapeto kwa sitiroko kumafunika kuti kukhale kosalala Popewa kukhudzidwa, silinda yokhala ndi chipangizo cholumikizira iyenera kusankhidwa.
