He aha ngā mowhiti piston
Ko ngā mowhiti piston he mowhiti whakarewa kua whakauruhia ki roto i ngā awaawa piston. Hei wāhanga matua o te miihini, ko ā rātou mahi matua he hiri, he whakawhiti wera, he waru hinu. E rua ngā momo: ngā mowhiti hau me ngā mowhiti hinu.
Youdaoplaceholder0 Te whakamāramatanga me te mahi a ngā mowhiti piston
Ko ngā mowhiti piston he wāhanga porowhita whakarewa e tāuta ana ki roto i ngā awaawa piston. Ko ā rātou mahi matua ko:
Youdaoplaceholder0 Mahi hiri : Hei ārai i te turuturu o te hau pēhanga teitei i roto i te rūma mura ki roto i te pouaka crank, kia pai ai te mahi a te miihini.
Pānga whakawhiti wera Youdaoplaceholder0 : Ko te wera e mimitihia ana e te tihi o te piston ka tukuna ki te pakitara rango ka marara mā te pūnaha whakamatao.
Youdaoplaceholder0 Te waru hinu me te tohatoha hinu : Ko te mowhiti hinu te kawenga mō te waru i te hinu taikaha i runga i te pakitara rango me te hanga i tētahi kiriata hinu ōrite hei whakaiti i te waku me te kakahu.
Youdaoplaceholder0 Hanganga me te whakarōpūtanga
Mowhiti hau (mowhiti hiri) :
Kei roto i ngā awaawa mowhiti tuatahi me te tuarua o te piston te nuinga o te wā, ā, ko te nuinga o te wā ka hiritia te hau mura.
Me ātete ngā rauemi ki te pāmahana teitei, me te kaha teitei hoki, pērā i te rino whakarewa, te rino ngāwari rānei.
Mowhiti hinu Youdaoplaceholder0 :
Kei roto i te awaawa mowhiti tuatoru, ka kohia te hinu miihini taikaha mā roto i te kōhao waru hinu hei ārai i te āhuatanga "tahu hinu".
Te taiao mahi me ngā āhuatanga rauemi
Ka mahi ngā mowhiti piston i raro i ngā āhuatanga pāmahana teitei, pēhanga teitei me te waku tere teitei, ā, me tutuki i ēnei whakaritenga e whai ake nei:
He pai tōna ngāwari, ā, ka piri pai ki te pakitara o te rango.
He tino ātete ki te pakaru, ā, ka taea te tu atu ki te waku reti mō te wā roa.
He kaha tōna ātete ki te wera, ā, ka taea te ārai i te rerekētanga me te pakaru i ngā pāmahana tiketike.
Ko ngā mahi matua o te mowhiti piston ko te hiri i te hau mura, te whakahaere i te kiriata hinu whakahinuhinu, te kawe i te wera me te tautoko i te nekehanga o te piston. He wāhanga matua tēnei mō te mahi pumau o ngā miihini mura ā-roto.
Ko te mahi matua o te mowhiti piston ko
Pānga hiri Youdaoplaceholder0 .
Hei ārai i te turuturu o te hau pāmahana teitei me te pēhanga teitei i roto i te rūma mura ki roto i te pouaka whakakā, me te whakarite i te whai huatanga o te pēhanga me te whiu mana (te mahi matua o te mowhiti hau).
Āraihia te hinu miihini kei uru ki te rūma mura mā te āputa i waenganui i te piston me te rango kia uru atu ai ki te mura (he mahi āwhina te mowhiti hinu).
Youdaoplaceholder0 Pānga whakahaere hinu .
Mā te mowhiti hinu, mā roto i tētahi hanganga motuhake i hangaia, ka waruhia te hinu miihini taikaha i runga i te pakitara o te rango, ka whakaitihia te whakapaunga hinu me te hanganga o ngā putunga waro.
I taua wā anō, ka hangaia he kiriata hinu ōrite ki te pakitara o te rango hei whakarite i te pānga whakahinuhinu i waenga i te piston me te rango.
Pānga kawe wera Youdaoplaceholder0 .
Tata ki te 70% ki te 80% o te wera e mimitihia ana e te pane piston ka tukuna ki te pakitara rango ka tukuna mā roto i te pūnaha whakamatao hei ārai i te piston kei wera rawa, kei pirau rānei.
Pānga tautoko a Youdaoplaceholder0.
Whakaitihia te ātete waku i waenga i te piston me te pakitara rango hei pupuri i te pumau o te nekehanga raina o te piston.
Ārai i te pakaru rerekē i puta mai i te pānga tika i waenga i te piston me te pakitara rango (e mōhiotia whānuitia ana ko te "knocking").
Te tikanga whakatinanatanga o te mahi
Hoahoa taurite pēhanga Youdaoplaceholder0 : Ka tutuki te hiri hihiri mā te whakakotahitanga o te pēhanga hau me te kaha ngāwari, kia mau tonu ai te hiri whai hua ahakoa te pakaru.
Huinga mowhiti maha Youdaoplaceholder0 : Ko te hanganga noa he mowhiti hau e rua me te mowhiti hinu kotahi, e aro ana ki te hiri hau me te whakahaere kiriata hinu.
Hangarau maimoatanga mata Youdaoplaceholder0: Whakarei ake i te ātete ki te kakahu me te whakaroa i te roa o te mahi mā te whakamahi i ngā tukanga pēnei i te whakakikorua chromium me te nitriding.
Ko ngā hapa o te mowhiti piston ka kitea nuitia i roto i te tahunga o te hinu miihini (pēnei i te paoa kikorangi e puta mai ana i te paipa hau), te pikinga rerekē o te whakapaunga wahie, te hekenga o te hiko me te pakaru o te hiri o te rango, me ētahi atu. Ko te nuinga o ēnei ka puta mai i te aukati o ngā putunga waro, te pakaru, te tāutanga hē rānei. Me tautuhi ngaio me te whakahaere wawe kia kore ai e kino te miihini.
Ngā āhuatanga hapa noa
Ko te pakaru o te mowhiti piston ka arahi i ngā tohu e whai ake nei:
Youdaoplaceholder0 Te āhua o te tahunga hinu : ka puta mai te paoa kikorangi i te paipa putanga hau, ā, ka piki haere te hinu e pau ana i te huarahi rerekē (hei tauira, neke atu i te 0.5 rita ia 1,000 kiromita).
Te hekenga o te mahi: Te ngoikore o te mana o te miihini, te ngoikore o te whakaterenga, me te pikinga o te whakapaunga wahie 30%-50%.
Youdaoplaceholder0 He rerekētanga ā-mīhini : ka piki ake te pāmahana o te putanga hau i te turuturu o te rango, ka rerekē te pāmahana wai i roto i te arai rango, ka rerekē rānei te haruru me te wiri.
Te tātaritanga o ngā tino take o
Ko ngā tino take o te korenga o te angitu ko:
Youdaoplaceholder0 Te aukati i te putunga waro : Mā te whakamahinga roa o te wahie iti iho te kounga, te taraiwa poto rānei, ka piri pea ngā putunga waro ki ngā āputa o ngā mowhiti piston, e 60% ki te 70% o ngā hapa, ka taea ai te mimiti o te hinu miihini ki roto i te rūma mura, ka tahuna.
Youdaoplaceholder0 Te pakaru, te pakaru rānei o te mowhiti piston : Mā te tiaki kore tika o te tātari hau ka puta te puehu, ka pakaru te awaawa mowhiti, ka ngenge rānei te tinana mowhiti, ka whakaiti i te mahi hiri.
Youdaoplaceholder0 He hapa tāutanga, he hapa hoahoa rānei:
He iti rawa te āputa o te mowhiti piston, ā, ka mau ki roto i te rango i muri i te whakawhanuitanga wera.
Nā te piko o te tokotoko honohono ka piko te piston i te wā e whakamahia ana, ka kore e ōrite te kakahu.
Ngā tikanga tātaritanga me te whakamātautau
Ko te tautuhi mate kua whakaūtia me whakamahi i te huinga o ngā tikanga ngaio:
Youdaoplaceholder0 Tirohanga tuatahi : Tuhia te hinu e pau ana, ā, tirohia mēnā ka puta te paoa kikorangi, te hau putanga hau kino rānei i te tīmatanga makariri.
Te kimi taputapu Youdaoplaceholder0:
Te tirotiro endoscopic o ngā putunga waro i runga i te pakitara rango, i te aukati rānei o te mowhiti piston.
Inehia te pēhanga o te rango (me teitei ake i te 10bar te tikanga). Mena he iti iho, he tohu kua pakaru te hiri.
