Gufunga A-Urwego: A-urwego rwo kurwanya ubujura rusanzwe rukoresha urufunguzo rwa A-rufunguye.Imiterere yimbere ya A-urwego rwo gufunga silinderi iroroshye, hamwe nibitandukaniro bike muri pin tumbler hamwe ninzira ntoya.Izi funga zirashobora gufungurwa byoroshye muminota umwe ukoresheje tekinoroji.Imiterere yumupira wa A-gufunga igizwe numurongo umwe cyangwa umusaraba wimipira yuzuye imipira.

Ifungwa rya B-Urwego: B-urwego rufunguye rugaragaza urufunguzo ruringaniye hamwe na pinhole ebyiri.Bitandukanye na A-gufunga, urufunguzo rwibanze rwa B-urwego rufite gahunda idasanzwe yimirongo igororotse.Hariho ubwoko butatu bwingenzi bwa B-urwego rwo gufunga silinderi: mudasobwa ebyiri-imirongo ya silinderi, imirongo ibiri ya dimple silinderi, hamwe na silinderi yibibabi bibiri.Izi funga zirashobora gufungurwa ukoresheje ibikoresho byo kugoreka muminota itanu, kandi akenshi zisangira ibipimo bihanitse.

Gufunga C-Grade (B + Grade): C-urwego rufunguye, ruzwi kandi nka B + urwego rufunze, rufite imiterere yurufunguzo rurimo icyuma kimwe cyuruhande rumwe hamwe n’ahantu ho gusya imbere, ahantu ho gusya hanze, cyangwa urufunguzo rw'imirongo ibiri hamwe icyuma.Ubwoko bwa silinderi yo gufunga ni silindari yo kuruhande, kandi pin imiterere igizwe nimirongo ibiri yumurongo hamwe na V.Niba igikoresho gikomeye cya torsion gikoreshwa muguhatira gufungura silinderi yo gufunga, uburyo bwimbere buzangirika, bitera gufunga kwiyangiza bidashobora gukingurwa.

A-Urwego rwo Kurwanya Ubujura:

Gusa urufunguzo rufite umurongo umwe wumupira ufatwa nka A-urwego rwo kurwanya ubujura, hamwe nurufunguzo ruciriritse nurufunguzo rwambukiranya ni ingero zisanzwe.Inkweto ziri ku rufunguzo, nubwo zidafite uruziga mu isura, zihuye n'imiterere yaigikumwe cyubwenge gifunga ubwenge'pin tumbler.Imiterere yimbere ya A-urwego rwo gufunga silinderi iroroshye, hamwe nibitandukaniro bike muri pin tumbler hamwe ninzira ntoya.

B-Urwego rwo Kurwanya Ubujura:

B-urwego rufunze rufite ubwoko bubiri bwinzira nyamukuru, imipira yumupira, hamwe no gusya.Ibiumuryango wumutekano ufunze amazuBisanzwe Byahujwe nurufunguzo ruringaniye rufite impande ebyiri-zishushanyije.Ubwoko bwibanze kuri B-urwego rufunguye rurimo urufunguzo rumwe rwimfunguzo nurufunguzo rumwe.Imiterere yimbere ya B-urwego rwo gufunga silinderi iraruhije ugereranije no gufunga A-urwego, rutanga urwego rwo hejuru rwumutekano urwanya ubujura.

(C-Grade Ifunga) B + Urwego rwo Kurwanya Ubujura:

Gufunga B + urwego, nanone byitwa C-gufunga, kuri ubu bifatwa nkumutekano.Uhereye ku rufunguzo rw'ibisobanuro, mubisanzwe bafite ibice bibiri-byerekeranye n'imirongo ibiri hamwe n'ibice byegeranye.Gufunga silinderi yimbere imbere bisaba iminota irenga 270 kugirango abatekinisiye babishoboye bafungure, bitanga umutekano wizewe.

Ubugenzuzi bwo Kurwanya Ubujura:

1. Reba urwego rwumutekano rwo gufunga: Mugihe uhisemo urugi rwo kurwanya ubujura, ni ngombwa guhitamo imwe ifite silinderi ya B + cyangwa C yo mu rwego rwa C.

2. Kugenzura Urugi rwo Kurwanya Ubujura: Theurugi rwubwenge urugi rukinzeigomba kugira isahani yicyuma ifite uburebure bwa byibura 3mm kugirango hongerweho uburinzi.

3. Reba Uburebure bw'ururimi nyamukuru rufunga: Uburebure bukomeye bwururimi nyamukuru rufunga kumuryango urwanya ubujura ntibugomba kuba munsi ya 16mm, kandi bugomba kugira ururimi rufunga.Niba iyi mikorere idahari, gufunga bifatwa nkutujuje ubuziranenge.
