Uruhare rw'Impeta Ishyigikira mu Miterere y'Ifunga ry'Ivalufu n'Ibintu Bikenewe Kwitabwaho

Impeta yo gushyigikira ibice nk'ibi, mu miterere yose y'impeta, ni iy'ibice by'ingenzi 'bihishe'. Abakoresha benshi ntibabyitaho cyane, ariko mu by'ukuri, iyo igishushanyo cyangwa uburyo bwo kuyitunganya bitarashyirwa mu bikorwa, imbaraga zo gukandagirana kw'impeta y'intebe ya valve, PTFE, bizagira ingaruka zikomeye, cyane cyane mu ihindagurika ry'umuvuduko mwinshi cyangwa ubushyuhe mu bidukikije rigaragara neza.

Twari twarigeze dukemura ikibazo cy’umushinga w’umukiriya wo muri Afurika y’Amajyaruguru, intebe ya valve ikoresha imiterere y’icyuma gihuza imiterere ibiri + imiterere y’ipfundo ihindagurika, impeta ya PTFE mu ishyirwaho rya mbere nta kibazo kirimo, ariko gukora nyuma y’amezi make habonetse kwangirika kw’imikorere yo gufunga, ndetse no guhinduka kw’ipfundo ry’ipfundo. Nyuma yo gusubira mu ruganda kugira ngo hasuzumwe umurambo, byagaragaye ko ikibazo cyari ukugabanuka k’ubunini bw’ipfundo ry’ipfundo + imbere mu gice cy’ipfundo cyari kinini cyane, bigatuma imbaraga zitangana.

Kuri iki kibazo, dutanga inama zikurikira: Icya mbere, gutunganya impeta yo gushyigikira ntibishobora 'gukurikije igishushanyo cy'uruziga' gusa, ahubwo icy'ingenzi ni uburyo bwo kugenzura ubushobozi bwo kwihanganira no gufunga; Icya kabiri, dukurikije uburyo ibikoresho bifunga bihagaze kugira ngo habeho umwanya wo gukanda, cyane cyane mu gice cy'icyuma cy'umuyoboro hamwe no kwaguka kenshi no gufunga impeta yo gushyigikira iyo ubuso bwo guhuza bumaze kurekura, biroroshye. Igitutu kizava ku gice cyoroshye cyo gufunga.

Mu cyiciro cyo gutunganya, impeta yo gushyigikira isabwa guhindurwa neza uhereye ku biti byarangiye cyangwa ku byuma bikomeye, kandi uruziga rw'inyuma, umwobo w'imbere n'intambwe bigomba kurangizwa mu buryo bumwe bwo gufunga kugira ngo bigenzure inzira n'uburyo ibintu bizenguruka. Iyo tuzungurutse bene ubu bwoko bw'ibice, muri rusange tugenzura ubukana bw'ubuso buri muri Ra 1.6, ubuso bw'urufunguzo Ra 0.8, tugahuza icyerekezo hakurikijwe icyerekezo cyo guteranya kugira ngo wirinde kwangirika ku nkengero z'impeta yo gufunga.

Nubwo igiciro cy'impeta yo gushyigikira kitari hejuru, ariko bigira ingaruka zikomeye ku buryo ipfundo ryose rya valve rihagaze neza. Ni byiza ko umukiriya uri mu cyiciro cyo gushushanya asobanura neza uko icyuma giteranywa, uburyo gishyirwamo ingufu n'aho giherereye, nibiba ngombwa, guha icyicaro cya valve cyangwa umubiri wa valve imiterere y'igishushanyo, kugira ngo duhuze isuzuma ry'imiterere rusange. Uruhande rwacu rushobora kandi gufasha mu kwigana imiterere y'ubushyuhe, mbere y'igihe kugira ngo hamenyekane ibyago byo kwimuka kwa valve mu gihe cy'umuvuduko mwinshi cyangwa ubushyuhe bwinshi.
