Mune zvimwe zviitiko, pane musiyano pakati pekuongororwa kweplate yepamusoro. Dzimwe nguva zvinhu zvakaita sekushanduka kwenzvimbo kunokonzerwa nekusakara, kushandiswa zvisirizvo kwemidziyo yekuongorora kana kushandiswa kwemidziyo isina kugadziriswa zvinogona kukonzera kusiyana uku. Zvisinei, zvinhu zviviri zvinonyanya kuzivikanwa itembiricha nerutsigiro.

Chimwe chezvinhu zvinonyanya kukosha itembiricha. Semuenzaniso, pamusoro payo panogona kunge pakagezwa nemvura inopisa kana inotonhora isati yagadziriswa uye pasina nguva yakakwana yekuigadzirisa. Zvimwe zvinokonzera kuchinja kwetembiricha zvinosanganisira mhepo inotonhora kana inopisa, chiedza chezuva chakananga, chiedza chepamusoro kana zvimwe zvinopisa pamusoro peplate.

Panogonawo kuva nekuchinja-chinja kwekushisa kwakamira pakati pechando nezhizha. Mune zvimwe zviitiko, ndiro haibvumirwi nguva yakakwana yekuchinja mushure mekutumira. Zvakanaka kunyora tembiricha yakamira panguva iyo calibration inoitwa.

Chimwe chikonzero chinowanzoita kuti pave nekusiyana kwekuenzanisa ndiro isina kutsigirwa zvakanaka. Pfuti yepamusoro inofanira kutsigirwa panzvimbo nhatu, zviri nani kuti ive ne20% yehurefu kubva kumagumo eplate. Zvitsigiro zviviri zvinofanira kunge zviri ne20% yehupamhi kubva kumativi marefu, uye chimwe chinosara chinofanira kunge chiri pakati.

Mapoinzi matatu chete ndiwo anogona kumira zvakasimba pane chimwe chinhu kunze kwenzvimbo chaiyo. Kuedza kutsigira ndiro panzvimbo dzinopfuura nhatu kuchaita kuti ndiro iwane rutsigiro rwayo kubva mumisanganiswa yakasiyana-siyana yepoinzi nhatu, izvo zvichave zvisiri nzvimbo nhatu dzakafanana dzayaitsigirwa pairi panguva yekugadzira. Izvi zvichaunza zvikanganiso sezvo ndiro ichitsauka kuti ienderane nehurongwa hutsva hwekutsigira. Funga nezvekushandisa zvigadziko zvesimbi zvine matanda ekutsigira akagadzirirwa kuenderana nenzvimbo dzakakodzera dzekutsigira. Zvigadziko zvechinangwa ichi zvinowanzo kuwanikwa kubva kumugadziri weplate yepamusoro.

Kana ndiro yacho yakatsigirwa zvakanaka, kuyera kwakanyatsojeka kunodiwa chete kana paine chinhu chakairatidza. Kuyera kwacho hakudiwi kuti plate yacho irambe yakarurama.

Zvakakosha kuchengetedza ndiro yakachena. Guruva rinoputika nemhepo rinowanzova ndiro rinonyanya kukonzera kusakara kwendiro, sezvo richiwanzopinda muzvishandiso zvebasa uye panzvimbo dzinobata mageji. Vhara ndiro kuti dzisaparare kubva kuguruva nekukuvadzwa. Nguva yekupfeka inogona kuwedzerwa nekuvhara ndiro kana isiri kushandiswa.

Wedzera Hupenyu hwePlati
Kutevedzera mitemo mishomanana kunoderedza kupera kweplate yegranite uye pakupedzisira, kuchawedzera hupenyu hwayo.

Chekutanga, zvakakosha kuchengetedza ndiro yakachena. Guruva rinoputika nemhepo rinowanzova ndiro rinonyanya kukonzera kusakara kwendiro, sezvo richiwanzopinda muzvishandiso zvebasa uye munzvimbo dzinobata mageji.

Zvakakoshawo kufukidza ndiro kuti dzisaparare kubva muguruva nekukuvadzwa. Nguva yekupfekwa kwayo inogona kuwedzerwa nekuifukidza kana isiri kushandiswa.

Tenderedza ndiro nguva nenguva kuitira kuti nzvimbo imwe chete isanyanya kushandiswa. Zvakare, zvinokurudzirwa kutsiva mapedhi esimbi ekubatanidza simbi pakushandisa mapedhi ecarbide.

Dzivisa kuisa chikafu kana zvinwiwa zvisina kupfava mundiro. Zvinwiwa zvakawanda zvine carbonic kana phosphoric acid, iyo inogona kunyungudutsa zvicherwa zvakapfava zvosiya maburi madiki pamusoro.

Kwekudzokera Pamwe Chete
Kana plate yegranite ichida kugadziriswazve, funga kana basa iri richiitwa panzvimbo yacho kana panzvimbo yekuenzanisa. Nguva dzose zviri nani kuti plate yacho idzokororwezve kufekitori kana kune imwe nzvimbo yakatsaurirwa. Zvisinei, kana plate yacho isina kunyanya kukuvara zvakanyanya, kazhinji iri mukati me 0.001 inch yekutsungirira kunodiwa, inogona kugadziriswazve panzvimbo yacho. Kana plate yakapfekwa kusvika padanho rekuti inopfuura 0.001 inch kubva pakushivirira kunodiwa, kana kuti yakakuvara zvakanyanya kana kuti yakakuvara, saka inofanira kutumirwa kufekitori kuti igayiwe isati yadzokororwazve.

Nzvimbo yekuyeresa ine michina nefekitori zvinopa mamiriro akakodzera ekuyeresa maplate uye kugadzirisa patsva kana zvichidikanwa.

Kungwarira kukuru kunofanira kuitwa pakusarudza nyanzvi yekuongorora nekugadziridza nzvimbo yacho. Kumbira mvumo uye tarisa kuti michina ichashandiswa nenyanzvi ine nzira yekuongorora inoteverwa neNIST. Ruzivo rwakakoshawo, sezvo zvichitora makore akawanda kudzidza kurovera granite nemazvo.

Kuyera kwakakosha kunotanga neplate yegranite chaiyo senzira yekutanga. Nekuona kuti pepa repamusoro rakavimbika nekushandisa plate yepamusoro rakagadziriswa zvakanaka, vagadziri vane chimwe chezvishandiso zvakakosha zvekuyera kwakavimbika uye zvikamu zvemhando yepamusoro.

Rondedzero yeKuchinja kweCalibration

1. Pamusoro payo pakagezwa nemushonga unopisa kana unotonhora usati wagadziriswa uye hapaipiwa nguva yakakwana yekuzviita zviri nyore.
2. Ndiro yacho haina kutsigirwa zvakanaka.
3. Kuchinja kwekupisa.
4. Madhirowa.
5. Zuva rakananga kana kumwe kupisa kunopenya pamusoro peplate. Iva nechokwadi chekuti mwenje wepamusoro hausi kupisa pamusoro.
6. Kusiyana kwemamiriro ekunze pakati pechando nezhizha. Kana zvichibvira, zivai mamiriro ekunze panguva iyo kucheneswa kunoitwa.
7. Plate haina kubvumidzwa nguva yakakwana yekudzoreredza mushure mekutumirwa.
8. Kushandisa zvisina kunaka michina yekuongorora kana kushandisa michina isina kurongwa.
9. Kuchinja kwemusoro kunokonzerwa nekupfekwa.

Mazano eTekinoroji
Nekuti kuyerwa kwese kwemutsara kunoenderana nepamusoro pekutarisa kwakarurama uko zviyero zvekupedzisira zvinotorwa, mapurati epamusoro anopa nzvimbo yakanakisa yekutarisa uye kuronga basa risati raitwa.

Kudzora kuenzana kwenzvimbo kusvika pakusimba kupfuura kuenzana kwese kunovimbisa kuchinja zvishoma nezvishoma kwechimiro chekuenzana kwenzvimbo, nokudaro zvichideredza zvikanganiso zvenzvimbo.
