Kuyera kumanikidzwa uye kutarisa chikamu chakakosha chemaitiro emazuva ano emaindasitiri. Kumanikidzwa kunofanira kuyerwa kunogona kutsanangurwa sezvikamu zvakasiyana zvichienderana nekutarisa kwekuyera. Kunyange zvazvo kuyera kumanikidzwa kuchigona kukwana kumashandisirwo mazhinji emaindasitiri, dzimwe nguva shandisa chishandiso chinoratidza kumanikidzwa kwakakwana.
Kumanikidzwa Kwakazara uye Kumanikidzwa Kwegeji
Mhepo yepasi rose ine huremu uye inogadzira kumanikidzwa kwayo. Huwandu hwekumanikidzwa kwemhepo hunonziwo ambient pressure, iyo inosiyana-siyana inosvika 101.325kPa (mamiriro ekunze akajairwa) zvichienderana nekukwirira nemamiriro ekunze. Musiyano mukuru wekumanikidzwa kwemhepo negeji uri pakuti kumanikidzwa kwemhepo kwakabatanidzwa here. Nzvimbo yekunongedzera kumanikidzwa kwegeji idzvinyiriro yemhepo nepo kudzvinyiriro yemhepo imhepo isina chinhu uko kudzvinyirirwa kwemhepo kusina zvachose. Saka kuverenga kudzvinyirirwa kwemhepo kunoratidza huwandu hwekudzvinyirirwa kwemhepo negeji.
Kumanikidzwa kunowanzo kuyerwa nekuyerwa kwekushanduka kwechinhu chinonzwa, uko rimwe divi rechinhu rinosangana nereferensi uye rimwe divi rinosangana ne process medium. Kune gauge pressure sensor, divi re diaphragm risingabatane ne medium rinoburitswa nemhepo kuti rienderane ne ambient pressure, zvichipa gauge pressure reading inova musiyano wekumanikidzwa pakati pe process ne atmospheric pressure. Ne absolute pressure sensor, diaphragm inosanganisirwa ne absolute vacuum chamber iyo yakavharwa zvachose. Sezvo sealed vacuum ichishandiswa se reference point, diaphragm deformation haikanganisirwi ne atmosphere.
Sezvo zvivako zvemaindasitiri zvichiwanzova nekukwira kwakafanana uye mashandisirwo azvo ekumanikidzwa asingakanganiswi nekuchinja kwekumanikidzwa kwemhepo, chiyero chechiyero chekumanikidzwa chakarurama zvakakwana kune akawanda maitiro. Zvisinei, mamiriro akasiyana anoda kumanikidzwa kwakazara, uko kusingaenderane nekuchinja kwekumanikidzwa kwemhepo. Matransmita ekumanikidzwa kwakazara anowanzoonekwa muminda yekugadzira makemikari, yendege, yeHVAC, kazhinji nekuda kwezvikonzero zvinotevera:
- ✦ Maitiro acho anoda kuchengetedza vacuum kana pressure yakaderera zvakanyanya, zvichiita kuti pave nekuyera kumanikidzwa kwakakwana kuti pave nechinhu chakakodzera.
- ✦ Maitiro acho anoshandiswa pakubvisa mweya kubva mumhepo (sublimation) kana kuti kuburitsa mweya kunze kwemhepo uye anoda kuziva simba rakazara rinosara mukamuri kuti aone kana maitiro acho apera.
- ✦ Ngarava iyi inoshandiswa pasi pemuchina wekuchenesa mvura kuti ideredze kufashaira kuri pakati nepakati uye kudzora kumanikidzwa kwakakosha.
- ✦ Munguva yekuedzwa kweinjini, kumanikidzwa kuri mu intake manifold kunowanzova pasi pekumanikidzwa kwemhepo uye kunodiwa pakuverenga huwandu hwemhepo.
Shanghai Wangyuaninyanzvi yekugadzira uye mutengesi wezvishandiso zvekuyera kwemakore anopfuura makumi maviri. Wangyuan inopa mhando dzakasiyana dzezvinotumira zvinodzvinyirirakuti muwane mhinduro dzekuyera dzinosanganisira absolute, gauge pamwe nekusiyana kwekumanikidza. Kana muine mubvunzo nezvesarudzo yematransmitter ekumanikidza aabsolute, ndapota inzwa wakasununguka kutibata nesu.
