Kumanikidzwa (pressure) zvinoreva huwandu hwesimba rinoitwa rakatarisa pamusoro pechinhu, pachikamu chimwe nechimwe. Kureva kuti,P = F/A, izvo zviri pachena kuti nzvimbo diki yekumanikidzwa kana simba rakasimba rinosimbisa kumanikidzwa kuri kushandiswa. Mvura/Mafuta negasi zvinogonawo kushandisa kumanikidzwa pamwe nepamusoro pakasimba.
Kumanikidzwa kwemvura kunokonzerwa nemvura panguva yekuenzana panzvimbo yakatarwa nekuda kwesimba regiravhiti. Huwandu hwekumanikidzwa kwemvura hakunei nehukuru hwenzvimbo yekubata asi nekudzika kwemvura kunogona kuratidzwa ne equation.P = ρghInzira yakajairika yekushandisa musimboti wekumanikidzwa kwemvurakuyera mwero wemvura. Chero bedzi huwandu hwemvura iri mumudziyo wakavharwa huchizivikanwa, sensor iri pasi pemvura inogona kupa kukwirira kwechikamu chemvura zvichibva pakuverenga kwekumanikidzwa kwakaonekwa.
Huremu hwemhepo iri mumhepo yepasi redu hwakakura uye hunoramba huchimanikidza pasi. Izvi zvinokonzerwa nekuvapo kwekumanikidzwa kwemhepo ndiko kunoita kuti pakuyera kumanikidzwa kugovaniswe mumhando dzakasiyana.
Mayuniti ekumanikidza akasiyana zvichienderana nemasimba ekumanikidza akasiyana uye mayuniti ehuwandu hwakakodzera hwemuviri:
Pascal - Chikamu cheSI chekumanikidzwa, chinomiririra newton/㎡, umo newton iri chikamu cheSI chesimba. Huwandu hwePa imwe hudiki, zvekuti mukuita kPa neMPa zvinonyanya kushandiswa.
Atm - Huwandu hwekumanikidzwa kwemhepo yakajairika, hwakaenzana ne101.325kPa. Kumanikidzwa kwemhepo chaiyo yemunzvimbo inochinja-chinja kusvika pa1atm zvichienderana nekukwira uye mamiriro ekunze.
Bhawa - Chiyero chechiyero chekumanikidzwa. Bhawa rimwe chete rakaenzana ne0.1MPa, zvishoma pane atm. 1mabr = 0.1kPa. Zviri nyore kushandura chikamu pakati pePascal nebhawa.
Psi - Mapaundi pa sikweya inchi, avoirdupois pressure unit inonyanya kushandiswa neUSA. 1psi = 6.895kPa.
Inchi dzemvura - Zvinotsanangurwa sekumanikidzwa kuri pasi pechikamu chemvura chakakwirira che 1 inch. 1inH2O = 249Pa.
Mamita emvura - mH2O ndiyo chinhu chinowanzo shandiswa parudzi rwekunyudzwa kwemhando yemvura inotapurirana.
Mayunitsi Akasiyana Anoratidzwa Ekumanikidza (kPa/MPa/bar)
Mhando dzeDzvinyiriro
☆Kudzvanywa kwegeji: Rudzi rwakajairika rwekuyerwa kwepressure yemaitiro zvichibva pakudzvanywa chaiko kwemhepo. Kana pasina kudzvanywa kwakawedzerwa kunze kwekukosha kwemhepo kwakakomberedza, kudzvanywa kwegeji kunenge zero. Kunova kudzvanywa kusina kunaka kana chiratidzo chekuverenga chiri minus, ukoshi hwayo hwakazara husingapfuure kudzvanywa kwemhepo yemuno kwakatenderedza 101kPa.
☆Kudzvanywa kwakavharwa: Kudzvanywa kwakabatwa mukati me sensor diaphragm inoshandisa kudzvanywa kwemhepo kwakajairika senzvimbo yekutanga. Inogonawo kuva yakanaka kana yakaipa, inonzi overpressure uye partial vacuum zvakateerana.
☆Kudzvanywa kwakazara: Kudzvanywa kwakavakirwa pavacuum chaiyo kana zvese zvisina chinhu zvachose, izvo zvingasanyatsoitika pasi pemamiriro ezvinhu akajairika pasi pano asi zvinogona kunge zviri pedyo zvikuru. Kudzvanywa kwakazara kungave zero (vacuum) kana kuti kwakanaka uye hakumbofi kwakava negative.
☆Musiyano wekumanikidzwa: Musiyano uripo pakati pekumanikidzwa kwemachiteshi ekuyera. Musiyano wacho unonyanya kunaka nekuti machiteshi ekumanikidzwa kwepamusoro nepasi anowanzo sarudzwa zvichienderana nekugadzirwa kwesystem yekushanda. Kumanikidzwa kwakasiyana kunogona kushandiswa pakuyera mazinga ematangi akavharwa uye serubatsiro kune mamwe marudzi emamita ekuyerera.
ShanghaiWangYuan, nyanzvi yekudzora maitiro kwemakore anopfuura makumi maviri inogadzira zvishandiso zvekuyera kumanikidzwa zvinogamuchira marudzi ese ezvinodiwa zvakagadzirwa pamhando dzemayuniti ekumanikidza. Zvigadzirwa zvese zvinoongororwa zvizere uye zvinoongororwa zvisati zvabuda mufekitori. Mamodheru ane chiratidzo chakakosha anogona kugadzirisa yuniti inoratidzwa nemaoko. Ndapota inzwa wakasununguka kutibata nesu nezve zvaunoda nemibvunzo yako.
