Okureeba omu bwijwire okuteera Valve

1. Okuteera n’enki .

Ekyoma ekirimu amaizi nikishukwa omu kiina ky’ekibumbe ekiine ekishushani ekihikire aha kicweka ekyo, kandi bwanyima y’okuguma, ekicweka ekiine ekishushani, obuhango n’omutindo gw’ahaiguru nikitunga, eki barikweta okusheenya. Ebintu bishatu ebikuru: okuteerana, okukora eky’okureeberaho, okushuka n’okuhamya. Ekirungi ekikuru: ebicweka ebigumire nibibaasa kuhangwa.

2. Okutunguura eby’okuteera

Okukora kukatandika omu myaka ya 1930 barikukoresa ebyoma by’omuyaga n’emiringo y’omushenyi gw’eibumba ogukozirwe abantu.

Omushenyi gwa sementi gukareebeka omu mwaka gwa 1933

Omuri 1944, ekika ky’omushenyi gw’omushenyi oguriho obufuki obugumire gukareebeka .

CO2 egumire amaizi endabirwamu omushenyi ekibumbe kyareebeka omu 1947

Omu mwaka gwa 1955, ekika ky’omushenyi gw’okujwara ebiriisa by’okwotsya kikareebeka .

Omu mwaka gwa 1958, ekibumbe ky’omushenyi ekitari ky’okuteekamu furan resin kikareebeka .

Omu mwaka gwa 1967, ekibumbe ky’omushenyi ekirikusheesheka sementi kikareebeka .

Omu mwaka gwa 1968, endabirwamu y’amaizi erimu ekirungo ky’ebihangwa ekareebeka .

Omu myaka 50 ehweire, emiringo mirungi y’okukora ebibumbe by’okuteera ebishushani omu miringo y’omubiri, nka: okuteera ebibumbe by’amaizi g’omubiri, omuringo gw’okukora ebibumbe by’okuteera amaizi g’omubiri (vacuum sealing molding), okukora ebibumbe by’okuteera ebishushani (lost foam molding), n’ebindi Emiringo y’okuteera etari emwe n’emwe erikwegamira aha bibumbe by’ekyoma. Nk’okuteera centrifugal, okuteera pressure mpango, okuteera pressure nkye, okushohoza amaizi, n’ebindi.

3. Ebintu ebiri omu kuteera

A. Okuhindurahindura n‘okuhindurahindura omu bwijwire. Ebintu byona eby’ekyoma. Okuteera tikurikugarukira aha buremeezi, obuhango n’ekishushani ky’ekicweka. Oburemeezi nibubaasa kuruga ahari giraamu nkye kuhika ahari bikumi bya tani, obuhango bw’ekisiika nibubaasa kuruga ahari 0.3mm kuhika ahari 1m, kandi n’ekishushani nikibaasa kuba ebicweka ebigumire munonga.

B. Ebintu ebingi ebikozirwe n’ebirikuhweraho nibiruga omu myanya mingi kandi n’eby’obuguzi bukye, nk’ebyoma ebishazirwe n’omushenyi.

C. Ebicupuri nibibaasa kutunguura okuhikiirira kw’ebipimo n’omutindo gw’aha mutwe gw’ebicupuri kurabira omu tekinologiya y’okucumita ey’omurembe, kugira ngu ebicweka bibaase kusharaho bikye kandi hatariho kushara.
