Mechine e lekanyang bakeng sa khatello ea ho lekanya

Khatello ea mechine e lekanyang - sesebediswa e (le disebediswa tse) bakeng sa ho lekanya entsprechen la khatello khase, mokelikeli. Devices ba classified ka mefuta e 'maloa, ho itšetlehile ka matšoao. Pele u khetha manometer bakeng sa ho lekanya khatello, o lokela ho ithuta ho specifics ea ho sebelisa ha bona.

Khetha sesebediswa ho ea ka lekanya khatello ea mefuta e fapaneng

- Khatello lekanyetsa bokhoni. Kofuto sebelisoa ho lekanya phapang positive, pakeng tsa khatello e feletseng le ho hatelloa ke barometric ka mefuta e fapaneng ho tloha 0,06 ho 1000 MPa.

- mechine e lekanyang. Mehato lephaka fihlela 40 kPa.

- na kokomba na aspirateur. Ho sebeletsa bakeng sa ho lekanya khatello tlase ambient (sepakapakeng) ho fihlela ho 100 kPa.

- mechine e lekanyang. Mehato hanyenyane feteletseng khatello e (40 kPa).

- mechine e lekanyang. Go lekanya Range tsamaisana karohano ya ho tloha - 20 ho ea ho + 20 kPa.

- manometers. Sena se akarelletsa khatello ea mechine e lekanyang bakeng sa ho lekanya khatello feteletseng (60 ho ea ho 240000 kPa), le lephaka (ho fihlela ho - 100 kPa).

- differential khatello ea lekanyetsa bokhoni. sesebediswa e etselitsoeng ho lekanya differential khatello.

Ka ho fetisisa tse neng li sebelisoa ke differential le ho hatelloa ke ho feletseng liletsa. Differential sesebediswa (mechine e lekanyang) bakeng sa ho lekanya phapang khatello e pakeng tsa melao ea boitšoaro e 'meli e bontšitsoeng. manometers feletseng bontša boleng khatello, ho sa tsotellehe hore liphetoho tse sepakapakeng.

Features, mehaho e manometers

Mechine e lekanyang bakeng sa ho lekanya khatello ea ba arotsoe ka mefuta e 'maloa, ho itšetlehile ka moralo le sebōpeho sa dihlahiswa: mokelikeli, deadweight, lera deformation, le deformation ho selemo tubular (Bourdon tube,). Dintlha tse thusang ho lekanya khatello ea phahameng tekanyo ea ho nepahala ha eona.

Diaphragm khatello ea mechine e lekanyang li sebelisoa moriana. Ba li hloekileng ho fetisisa ha ho tluoa tabeng ea tikoloho, boleng ha hobe le ho feta mercury.

Ke mechine e lekanyang tloaelehileng haholo bakeng sa ho lekanya khatello khase. Ba akarelletsa ho e le 'mele eo ho eona ho na le limithara tse. Devices hlomamisa ka compressors, lipompo, thepa khase. Khase mechine e lekanyang li nepahetse ka ho bala.

Mechine e lekanyang ea mofuta ofe kapa ofe ba classified ho latela ho nepahala ha litsupa. The nyenyane palo, sesebelisoa sa bontša ka boleng feta nepahetse. litlelase ho nepahala ke tse latelang: 0,15; 0,25; 0,4; tse 0.6; 1,0; 1.5; 2,5; 4.0.

Boholo mechine e lekanyang

Morero mechine e lekanyang tse ngata. Li kopana motlakase, kakaretso botekgeniki, litšupiso, e le motlalehi, e leng morero oa khethehileng.

- motlakase o ikopanye manometer e sebediswa ho laola le tekanyo khatello ea ka gaseous libakeng mokelikeli,, bao e seng e senyang.

- mechine e lekanyang Obshchetehnichesky sebelisoa ho lekanya khatello ea mouoane, khase, mokelikeli.

- Reference mechine e lekanyang na le palo e phahameng ka ho nepahala. Ba hlahisa liteko le lekanyetsa tsa lisebelisoa tse ling. Ka kakaretso, ba ile ba ba kenya ka deadweight tsa sesebediswa.

- Khatello mechine e lekanyang le motlalehi e tsitsitseng khatello ea ho bala ka mochine o khethehileng oa microcyteme le.

- Khatello mechine e lekanyang merero e khethehileng ho fana ka a lakatsa maemo a tikoloho. Tsena li akarelletsa: oksijene (putsoa), acetylene (tšoeu), hydrogen (putsoa-tala) le disebediswa tse. mebala e fapaneng ho hlokahala hore ba qobe liphello tse mpe. Ka mohlala, disebediswa tse oksijene tlameha ho degreased, kapa silafalitsoe ka sesebediswa kopana le oksijene e hloekileng ea phatloha.

Khatello ea lekanyetsa bokhoni ba ho lekanya khatello ea mafura a ka sebelisoa ka liindasteri tse sa tšoaneng. Ha a khetha sesebelisoa, u lokela ho tseba hore sehlahisoa sa boleng ka rekoa feela ho tswa ho le botumo bo botle moetsi le le botumo bo lefatšeng ka bophara. The moetsi lokela ho ba le lengolo la ho bothata thepa, lengolo la boleng. Sena ke 'nete ea bohlokoa haholo. Ka mor'a ho lekanya le disebediswa tse sebelisoang ka ho rarahaneng dithulaganyo theknoloji le tlhahiso. 'Me ba fumana hore na polokeho tsa tsoela pele le boleng ba sehlahisoa ho qetela.
