1. Huwandu hwechigadzirwa hahufanire kudarika 25% yevhoriyamu yebhokisi remidziyo, uye sampuli base haifanirwe kudarika 50% yenzvimbo yakatwasuka yenzvimbo yebasa.

2. Kana saizi yemuenzaniso isingaenderane nechirevo chekare, zvirevo zvakakodzera zvinofanirwa kutsanangura kushandiswa kwenzira dzinotevera:

① Iyo jecha uye guruva bvunzo kamuri inoedza zvinomiririra zvikamu zvechigadzirwa, zvinosanganisira zvinhu zvakaita semagonhi, magonhi emhepo, zvitsigiro, kuvhara shafts, nezvimwe.
② Edzai masampuli madiki ane dhizaini yakafanana neyechigadzirwa chekutanga.
③ Edzai chikamu chekuisa chisimbiso chechigadzirwa zvakasiyana;

Zvikamu zvakanaka zvechigadzirwa, senge materminals uye coil coil, zvinofanirwa kuchengetwa munzvimbo panguva yekuedzwa;

Thejecha neguruva test chamberinobva pamamiriro ekushanda echigadzirwa. Chigadzirwa casing chinogona kukamurwa kuva marudzi maviri:

1: Kumanikidzwa mukati mechigadzirwa casing kunogona kusiyana nekunze kwekunze kwemhepo, semuenzaniso, nekuda kwekusiyana kwekumanikidzwa kwemhepo kunokonzerwa nekutenderera kwekupisa panguva yekushanda.
Kune masampuli ane Type 1 casing, iise mukati mebhokisi remidziyo uye uiise munzvimbo yavo yakajairika yekushandisa. Iyo jecha uye guruva rekuyedza bhokisi rakabatana kune vacuum pombi kuti ive nechokwadi chekuti kudzvanywa kwemukati kwemuenzaniso kwakadzikira pane kudzvanywa kwemhepo. Nechinangwa ichi, maburi akakodzera anofanirwa kupihwa pane casing. Kana pachitova nemakomba emvura pamadziro emuenzaniso, chubhu yevacuum inofanira kubatanidzwa negomba iroro pasina kudiwa kwekuchera patsva.

Kana pane gomba rinopfuura rimwe remvura, iyo vacuum chubhu inofanira kubatanidzwa kune imwe yegomba, uye mamwe maburi anofanira kuvharwa panguva yekuedzwa.

2: Mhepo inotsikirira mukati meiyo sampuli casing yakafanana nekumanikidza kwekunze. Kune masamples ane Type 2 shells, iise mukamuri yekuyedza uye uiise munzvimbo yavo yakajairika yekushandisa. Maburi ese akashama anoramba akavhurika. Zvinodiwa uye mhinduro dzekuiswa kwezvimedu zvebvunzo mubhokisi remidziyo.
Izvo zviri pamusoro ndizvo zvese zviri mukati mekuiswa uye zvinodiwa zvejecha uye guruva test boxyezvigadzirwa zvebvunzo.
