Pressure test njira ya valavu ya mpira

Kuyesa kwamphamvu kwa valavu ya pneumatic mpira kuyenera kuchitidwa pansi pavuto lotseguka. ① Mayeso osindikizira a valve yoyandama: ikani valavu pamalo otseguka, yambitsani njira yoyesera kumapeto kwina ndikutsekanso; tembenuzani mpirawo kangapo, tsegulani mapeto otsekedwa pamene valavu ili mu malo otsekedwa kuti awonedwe, ndipo yang'anani ntchito yosindikiza ya kunyamula ndi gasket nthawi yomweyo, popanda kutayikira. Kenako yambitsani njira yoyesera kuchokera kumapeto ena ndikubwereza mayeso omwe ali pamwambapa. ② Mayeso osindikizira a valve yokhazikika ya mpira: musanayambe kuyesedwa, tembenuzani mpirawo kangapo popanda katundu, ndipo valve yokhazikika ya mpira imakhala yotsekedwa. Yambitsani sing'anga yoyesera kuyambira kumapeto mpaka mtengo womwe watchulidwa; yang'anani momwe ntchito yosindikizira ya kutsogolera kumapeto ndi choyezera champhamvu. Kulondola kwa kuyeza kwamphamvu ndi 0.5-1, ndipo mitunduyi ndi nthawi 1.5 ya kukakamizidwa kwa mayeso. Ngati palibe vuto la dontho la kuthamanga mkati mwa nthawi yotchulidwa, ndiloyenera; ndiye njira yoyesera imayambitsidwa kuchokera kumalekezero ena, ndipo mayeso omwe ali pamwambawa akubwerezedwa. Kenako, valavu ili mu semi yotseguka, malekezero onse atsekedwa, ndipo mkati mwake muli odzaza ndi sing'anga. Pansi pa kukakamizidwa kwa mayeso, fufuzani zonyamula ndi gasket, ndipo sipadzakhala kutayikira. ③ Mavavu a mpira wanjira zitatu ayesedwe kuti azitha kulimba pamalo onse.
