Rifle RFP: imithetho Ukukhetha, umlando futhi abanye izincomo

Ngokubukeka, entwasahlobo-piston indlela kule isikhali kubonakala yisikhathi futhi ungasizi. Rifle IFR, nakuba has a isakhiwo eyinkimbinkimbi uma ziqhathaniswa nezinye izinhlobo izikhali womoya, kodwa ingenye zezinhlobo unomphela kubalandeli kwezemidlalo ukuqeqeshwa sokudubula. Kunezici eziningi ezithinta izinga kanye nomthamo indlela entwasahlobo-piston, ngakho ukuthola kukho efanelekayo kuthatha isikhathi eside.

Beginners abalandeli ngokuvamile kakhulu RFP is ngezibhamu womoya atholwe njengoba amakhono ayisisekelo, futhi kuphela ngemva kokuba ucwaningo enemininingwane wabo udlulela ezinye izinhlobo ezemidlalo izikhali.

Ukuthembeka entwasahlobo-piston iyunithi wukuthi akukho simiso dlula valve kanye amadamu equkethe emoyeni onomfutho. Ngaphakathi uMbhalo kukhona inqubo ukunyakazisa piston ngoba ukugxisha isiphethu. Nale zikhali cocked futhi isesikhundleni labadubuli inhlamvu. Lapho entwasahlobo ikhishwe futhi badutshulwa nge force ngokugcwele ushukumisela piston, okuyinto licindezele emoyeni futhi usebenzisa umfutho ophakeme odlulela inhlamvu. I isibhamu ifakwe IFR iyunithi akancike ngokuphelele, ngakho ukusebenzisa kwayo Akudingi-add. Engingakusho nje ukuhlanekezela icala indlela bese ufaka igobolondo ku izikhali breech.

IFR isibhamu imali yesondlo elula futhi kulula. Small ngokwanele ukuba babe namakhono obuchwepheshe ukuqaqa futhi gcoba izingxenye zangaphakathi. Spring-piston indlela muhle ngoba sekunesikhathi eside ngokunembile kakhulu isibhamu. Isizathu esiyinhloko ushintsho ijubane inhlamvu - a bafake mainspring metal.

Ukuze uthole inombolo ethile isibhamu lucetu sikhubazekile. Buthaka nomthelela zonke izindlela kudivayisi. Ephansi okusalungiswa entwasahlobo ayinikeze kunesidingo umfutho womoya kwesigubhu, kanjalo ngokuphawulekayo eziwohlokayo ijubane inhlamvu. Kodwa-PPP sokuzingela wabuthela kusuka izingxenye eziningi, okuvumela esikhundleni kuyashesha futhi kulula izingxenye ezigugile.

Izici ngokudubula isibhamu ne indlela entwasahlobo-piston itholakala lokuthi ukuthi umphumela kanye nekhwalithi isibhamu bathembele ngokuphelele isikhundla nokudubula. Ithonya nezindlela eliyifa, izingubo kanye iziphi izici zangaphandle. Ezenye amandla ezahlukene inhlamvu nezinhlobo ezahlukene izinhlamvu zingase zishintshe kakhulu futhi uphica imfundamakhwela nokudubula. Ngezikhathi ezinjalo, lezi zifiki aqale ukulungisa nokuzwa eyiphutha futhi liqalise kabusha sextant. Kodwa lezi zenzo ezingalungile. Ngemva ushintsho izinhlamvu izoshintsha futhi. Empeleni, konke kuncike izinga, isisindo kanye ububanzi we izinhlamvu esetshenziswa.

Nge yesondlo efanele, ukukhanda esifike ngesikhathi futhi kunakekelwa kahle izikhali ezinjalo izothatha iminyaka eminingi. Kuze kube manje, kukhona DVP-1905 ngezibhamu, okuyinto zisasetshenziswa futhi abe nezimfanelo usesemuhle lobuchwepheshe. Ngakho-ke, lesi sikhali lokuqala womoya ngokudubula ukuqeqeshwa kahle isampula bufaneleke spring-piston indlela.
