Dalilin Binciken Lalacewar Piston

Game da na'ura mai ba da hanya tsakanin hanyoyin sadarwa, kamar yadda muka sani, tasirin piston yana da mahimmanci a cikin jerin abubuwan da suka fi mahimmanci. Dangane da gazawar fistan, galibi shine ya fi yawa, kuma gabaɗaya yana haifar da gazawa mai tsanani, kuma nau'ikan gazawar suna fitowa ba tare da ƙarewa ba.Saboda haka, HMB ya taƙaita dalilai da yawa na gazawar piston.

1.Scratches a kan aiki surface, Piston iri crack

Dalili:

● ƙananan taurin ƙasa

Yi amfani da na'urar gwaji don auna taurin ainihin (35 ≥ 45 shine ƙimar tazarar da aka yarda da ita) musamman mai saurin lalacewa ④ Bayan fashewar ya bayyana, haƙuri a gefe ɗaya zai faɗaɗa a cikin dubun na wayoyi, ta haka zai lalata gibin al'ada. tsakanin fistan da silinda, yana haifar da matsala mai tsanani.

● Abubuwan da aka haɗe a cikin man hydraulic

● Tazarar da ke tsakanin hannun rigar sandar rawar soja (dutse na sama da na ƙasa) ya yi girma da yawa, kuma hannun rigar ya gaza.

Lokacin da sandar rawar soja ke aiki, axis yana karkata. Lokacin da fistan ya bugi sandar rawar soja, yana karɓar ƙarfin amsawa, wanda zai iya lalata ƙarfin axial da ƙarfin radial, kuma ƙarfin radial na iya tura piston zuwa gefe ɗaya, rata ta asali ta ɓace, fim ɗin mai ya lalace, bushewa. an samu gogayya tsakanin silinda da saman fistan, kuma an tarar da saman piston a sakamakon haka.

2.katse fistan

Dalili:

① Matsalar kayan aiki

The carburized low-alloy karfe piston ne na ciki dalilin da tasiri karshen fuska ciki ciki da fasa.

Bambancin taurin da ke tsakanin ɓangaren bugun fistan da taurin sandar rawar soja ya kamata ya dace.

②Matsalar maganin zafi

A lokacin ƙirƙira ko magani mai zafi, kayan piston suna samar da tsagewa, wanda ke faɗaɗa ƙwanƙwasa har sai sun karye a ƙarƙashin aikin musanyawa.

3.The piston yana da rami mai zurfi, kuma jikin silinda yana da ma'ana mai ma'ana mai tsayi mai tsayi;

Dalili:

① Shigar da ƙazanta, yana haifar da piston don rasa daidaito a gaba da baya, tare da tunanin karkatar da kai, yana haifar da damuwa.

② Cavitation, cavitation gabaɗaya yana faruwa a cikin silinda, ba akan fistan ba. Cavitation zai haifar da rami mai zurfi na baki, kuma abubuwan da suka wuce gona da iri a cikinsa za su lalace a cikin saurin tasirin mai na hydraulic, kuma dukkanin silinda za su kasance masu rauni.

③Ramin tsatsa, kamar yadda aka nuna a hoto ba ramukan tsatsa ba ne. Tushen tsatsa galibi ana haifar da su ta hanyar kayan piston (misali, wasu masana'antun suna amfani da 42CRMO ko kawai suna amfani da 40CR da sauran kayan saboda matsin kasuwa) ko kuma lokacin adanawa, ba su kula da tura piston cikin silinda ba. A cikin kwanakin damina, Lalata yana haifar da dogon lokaci, kuma tsatsawar rawaya ta juya zuwa baƙar fata kuma a ƙarshe ta zama rami. Gabaɗaya, wannan al'amari ya zama ruwan dare ga ƙanana da ƙananan ƙwayoyin cuta waɗanda ke fara zubar da mai kafin lokacin kulawa.

IDAN kuna da wani abu, don Allah ku ji daɗin tuntuɓar mu! Mu magance matsalar tare, ku zo!!
