Nekuda kwenzvimbo dzakasiyana dzekushandisa uye nekuita zvinodiwa,castings zvigadzirwa zvezvinhu zvakasiyana-siyanavangangoda kuita bvunzo dzekumanikidza kuti vaone mashandiro avo uye kuchengetedzeka pasi pemamiriro ekumanikidzwa. Kuyedzwa kweHydrostatic uye pneumatic kuyedza nzira dzakajairwa dzekumanikidza, dzinonyanya kushandiswa kutarisa kusimba uye kudzvanywa kunotakura kugona kwepombi, zvishandiso kana midziyo.
1. Hydrostatic Testing
Hydrostatic pressure test inzira yekudzvanya bvunzo inoshandisa mvura seye test medium. Inowanzo shandiswa kuyedza kuramba kumanikidza uye kuiswa chisimbiso kwemidziyo yakaita semapaipi, midziyo yekumanikidza, boilers, matangi ekuchengetedza,mavharuvhu nemapombi, nezvimwewo pasi pekumanikidzwa kwekushanda.
Working Principle:
Nekuzadza midziyo kana pombi nemvura, zvishoma nezvishoma wedzera kumanikidza kwemvura kusvika 1.5 kusvika 2 nguva yedhizaini yekushanda (kazhinji pachange paine zvinodiwa zvakajairwa), uye chengetedza kwenguva yakati (kazhinji maminitsi makumi matatu kusvika maawa mashoma) tarisa kana paine mvura inobuda, kuwedzera kana mamwe matambudziko.
Chinokosha chekuongorora hydrostatic ndechekuona kuti mvura haina mabhubhu panguva yekuyedzwa (hapana mhepo yakamanikidzwa kana gasi inoshandiswa), nekuti iyo incompressibility yemvura inoita kuti kuvuza kuve nyore kuwana.
Zvakanakira:
Mvura haiwedzere panguva yekuyedzwa, saka inogona kuburitsa imwe yechokwadi yekushushikana bvunzo maitiro.
Mvura yakagadzikana, iri nyore kuwana uye inodhura.
Unogona kuwana zvirinani mavuza madiki.
Zvakaipa:
Drainage uye kuchenesa zvinodikanwa panguva yekuyedzwa, izvo zvinogona kukonzera tsvina kana mamwe matambudziko ekushanda.
Haikodzeri zvimwe zvemidziyo zviri nyore kuita ngura kana kukanganiswa nemvura.
Mamiriro ekushandisa:
Kumanikidzwa kuyedzwa kwepombi, boilers, matangi ekuchengetedza, nezvimwe.
Kuongororwa kwemidziyo mumaindasitiri akadai seoiri, gasi, uye makemikari.
2. Pneumatic Testing
Pneumatic pressure test inzira inoshandisa gasi (kazhinji yakadzvanywa mweya kana nitrogen) seyeyedzo svikiro. Muedzo uyu unowanzo shandiswa kumidziyo isina kukodzera mvura kana inoda kuongororwa tembiricha yakaderera.
Working Principle:
Zadza midziyo kana pombi negasi, zvishoma nezvishoma wedzera kudzvanywa kwegasi, uye tarisa iyo yekumanikidza geji kuti uone kuti michina inogona kumirisana neyakafanotemerwa yakanyanya kushanda kumanikidza.
Panguva yekuyedzwa, unofanirwa kungwarira nekuti gasi rinodzvanywa zvakanyanya uye rinogona kuburitsa masimba ane njodzi (sekuyerera kwemhepo inoputika) kana ichidonha.
Zvakanakira:
Nzira yekuedza iri nyore uye midziyo iri nyore kushanda.
Zvishandiso zvisina kukodzera kuongororwa kwemvura, senge midziyo yemagetsi, midziyo yekupisa, nezvimwewo, inogona kuongororwa.
Hapana mvura inoda kuburitswa panguva yekuyedzwa, izvo zvinogona kuderedza kusvibiswa kwezvakatipoteredza.
Zvakaipa:
Gasi rinodzvanywa zvakanyanya, uye kana kuvuza kukaitika panguva yekuyedzwa, inogona kuunza njodzi huru yekuchengetedza.
Pakudonha kudiki, kuongororwa kwepneumatic kunogona kunge kusiri nyore uye nyore kuwana sekuyedzwa kwemvura.
Mamiriro ekushandisa:
Kuedzwa kwemidziyo yemagetsi uye pneumatic systems.
Zvishandiso zvisina kukodzera kuongororwa kwemvura, senge mamwe emhando yepamusoro-tembiricha kana yakaderera-tembiricha midziyo, makemikari reactor, nezvimwe.
Kuongororwa kwekuchengetedza kwemapaipi egasi kana akamanikidzwa gasi masisitimu.
