Boiler chubu hydrostatic test

Machubu a boilerndi chinthu chofunikira pakupanga ma boilers, chikhala chokhudzana mwachindunji ndi momwe ma boiler amapangidwira bwino kuti azitha kuyika ndikugwiritsa ntchito bwino.Ubwino wa chubu cha boiler uyenera kupangidwa ndi zitsulo zokhala ndi zitsulo kuti zitsimikizire, koma pakachepa, zomwe zimaperekedwa ku chitoliro cha boiler chomwe chimagwiritsidwa ntchito ndi wopanga boiler nthawi zonse zimakhala ndi zovuta zina, makamaka zimagwiritsa ntchito zida zopopera za boiler monga chubu lamadzi, machubu otenthetsera, machubu otenthetsera, machubu otenthetsera akuwotchera kapena kuphulika kwa mapaipi achitika, chakhala vuto lalikulu lomwe lasokoneza mtundu wa boiler, opanga boiler ndi ogwiritsa ntchito ndi malingaliro.Pankhani ya msika wogulitsa, wopanga zowotchera pafupifupi amakhala ndi udindo wonse pazakudya, kuphatikiza;momwe mungayang'anire mtundu wa boiler tube boiler opanga akukhudzidwa kwambiri ndi vutoli tsopano lakhala lolemera kwambiri pamayeso a boiler chubu hydrostatic.

China dziko muyezo GB3087-82 otsika kuthamanga kukatentha kukatentha opanda zitsulo chitoliro: zitsulo chitoliro kwa kuyezetsa hydrostatic ayenera kukhala kunja ndi muzu, ndondomeko ntchito zofunika zofunika luso, osati kutayikira kapena thukuta chodabwitsa.20 chitsulo pazipita mayeso kuthamanga 9.8MPa, kupirira voteji sadzakhala zosakwana 5 masekondi.Kuthamanga kwa hydrostatic test kumawerengedwa motere: P = 2 * S * T / D

Njira: P - kuthamanga kwa mayeso, mu MPa;s - makulidwe a khoma la chitoliro chachitsulo, mm;D - m'mimba mwake kunja kwa chitoliro chachitsulo, mm;T - Steel No. adakonzeratu zokolola za 60%, MPa

Nthawi zambiri amakhulupirira kuti cholinga cha kuyesa kwa hydrostatic mitundu iwiri: imodzi ndi kuyesa kwa hydrostatic ya luso, cholinga chake ndikuyesa zida (kapena zigawo) za kutulutsa, kusindikiza kusindikiza kwa zinthu zoyeserera;wina testatory hydrostatic test Cholinga ndikuyesa mphamvu ya zinthu (kapena membala) ngati zokwanira.Kuchokera apa tikutha kuwona, kuyesa kwa hydrostatic kwa chubu chowotchera ndi njira yoyeserera ya hydrostatic, kuyesa kachulukidwe kazinthu, zoyeserera zimapitilira komanso ngati wandiweyani;sikutsimikizira kuyesa mphamvu.Kuwoneka kuchokera ku mphamvu ya chiphunzitso cha makina azinthu, machubu achitsulo osasunthika ndi opyapyala komanso aatali gawo, m'mimba mwake yaying'ono, makulidwe ochepera a chubu chocheperako pansi pamavuto ambiri.
