Okwetantara n'okujanjaba okusheeshasheesha kw'ekihuguhugu

Okusheenya ni kiza valvu z'ekihuguhugu?

Okusheenyagura kwa valvu z‘ebinyonyi nikukira kwetegyerezibwa nk‘okushiisha kw‘ekintu ky‘ekyoma kya valvu ahansi y‘ebikorwa by‘eby‘obuhangwa nari eby‘amashanyarazi. Ahabw‘okugira ngu ekikorwa kya “okusheenya” nikibaho omu kukwatiraine kw‘okwetunguura ahagati y‘ekyoma n‘ebintu ebirikwehinguririza, oku orikubaasa kutaanisa ekyoma kuruga omu by‘obuhangwa ebikyehinguririize nari okukoresa ebintu bingi ebitari by‘ekyoma eby‘obuhangwa nikyo kirikuteebwaho omutima omu kwerinda okusheenya. Omubiri gw’omuntu .valvu y'ekihuguhugu(obariiremu n‘ekifundikizo kya valvu) nikitwara oburemeezi bwingi bwa valvu kandi nikikira kukwatagana n‘omugati, n‘ahabw‘ekyo valvu y‘ebinyonyi neekira kutooranwa kuruga omu bintu by‘omubiri.

Hariho emiringo ebiri yonka ey’okusheeshasheesha kw’omubiri gwa valve ogwa .za valvu z'ekihuguhugu, nikwo kugira ngu okusheenya kw’eby’obuhangwa n’okusheenya kw’eby’amashanyarazi. Omubaro gwayo gw’okusheenya nigumanyirwa aha bwire bw’obutagatsi, oburemeezi, emibazi y’omugati, n’okusheenya kw’ekintu ky’omubiri gwa valve. Omubaro gw’okusheenya nigubaasa kugabwa omu mitwe mukaaga:

1. Okuzibira okusheeshasheesha okuhikire: omubaro gw’okusheeshasheesha guri ahansi ya 0.001 mm/omwaka;

2. Okuzibira okusheenya munonga: omubaro gw’okusheenya 0.001-0.01 mm/omwaka;

3. Okuzibira okusheenya: omubaro gw’okusheenya 0.01-0.1 mm/omwaka;

4. Okuzibira okusheenya kw’amaani: omubaro gw’okusheenya 0.1-1.0 mm/omwaka;

5. Okuzibira okusheenya kubi: omubaro gw’okusheenya 1.0-10 mm/omwaka;

6. Okutazibira okusheenya: omubaro gw’okusheenya nigukira ahari mm 10/omwaka.

Oku orikubaasa kuzibira okusheeshasheesha kw’za valvu z'ekihuguhugu?

Okurwanisa okusheeshasheesha kw’omubiri gwa valve ya valve y’ekinyonyi nikikira kubaho ahabw’okutoorana gye ebintu. N’obu amakuru agarikukwata aha kukyebera garaabe gari maingi munonga, tikyorobi kutoorana ekihikire, ahabw’okuba ekizibu ky’okukyebera kigumire munonga, eky’okureeberaho, sulfuric acid neesheenya munonga eby’ekyoma byaba biri bikye, kandi byaba biri bingi, nikireetera ekyoma kureetaho ekishushani ky’okukyebera (passivation film), ekirikubaasa kuzibira okukyendeera; Hydrogen neeyorekwa kwonka ngu neebaasa kusheenya munonga ebyoma aha bwire bw’obutagatsi bwingi n’okugyemeserezibwa, kandi obushoboorozi bw’okusheenya bwa gaasi ya chlorine tiburi bwingi ku buraabe bwomire, kwonka obushoboorozi bw’okusheenya nibuba buri bw’amaani munonga haaba hariho obutagatsi obumwe, kandi ebintu bingi tibirikubaasa kukoresibwa. Oburemeezi bw‘okutoorana ebikwato by‘omubiri gwa valvu n‘okugira ngu titurikubaasa kuteekateeka aha bizibu by‘okusheeshasheesha byonka, kureka n‘okuteekateeka aha bintu nk‘okuzibira okugyemeserezibwa n‘obutagatsi, yaaba nibihikaana n‘eby‘entaasya, n‘obu biraabe kyorobi kugura. N’ahabw’ekyo oine kufayo.

1. Ekyakabiri n’okutwara emiringo y’okukingiraho, nk’ekyoma ky’okuteeraho, aluminiyamu, obuveera bw’eby’obuhangwa, emipiira y’obuhangwa n’emipiira etari emwe n’emwe ey’obuhangwa. Embeera z‘ahagati zaaba niziikiriza, ogu n‘omuringo gw‘okubiika.

2. Ekyakashatu, pressure n’obutagatsi byaba bitari bingi, ekintu kikuru eky’ekipande ky’ebinyonyi ekirimu fluorine nikibaasa kukora gye munonga omu kuzibira okusheenya.

3. Okwongyera ahari ekyo, orubaju rw’aheeru rw’omubiri gwa valve narwo nirusheenyagurika ahabw’omuyaga, kandi ekintu ky’ekyoma ekirikuhindukahinduka okutwarira hamwe nikirindwa okukiteekaho nickel.

TWS juba neija kutandikaho omubaro musya gw’ebintu ebirikurwanisa okusheeshasheesha, ebirikukwata aha miringo yoona ey’okushoboorora enshonga za valve nk’za valvu z'ekihuguhugu, za valvu z'omuryango, kyebera za valvuna valvu z'omupiira, nebindi. Omubaro ogu gw’ebintu nigukoresa tekinologiya y’omurembe ey’okuzibira okusheenya n’emiringo y’omutaano ey’okujanjaba ebintu kubaasa kuguma n’okukora gye omu kukinga n’okuguma omu mirimo omu mbeera z’okukora ezigumire munonga. Twehaireyo kuha abashuubuzi ebintu by’amakorero ebigumire, kwongyera munonga aha myaka y’obuheereza bw’ebikwato, okukyendeeza aha sente z’okubiboneza omu magara goona .okuhindukaomuzingo, n‘okuhwera abashuubuzi kuhikiiriza ensharamu z‘okugura ez‘omuhendo gw‘ahaiguru.
