Kutsikirira ndiko kuwanda kwesimba rinoitwa perpendicular pamusoro pechinhu, pachikamu chechikamu. Kureva kuti,P = F/A, kubva izvo zviri pachena kuti nzvimbo diki yekushushikana kana simba rakasimba rinosimbisa kudzvanywa. Liquid / Fluid uye gasi zvinogona zvakare kuisa kudzvanywa pamwe nekusimba kwepasi.
Hydrostatic pressure inoitwa nemvura pakuenzanisa panzvimbo yakapihwa nekuda kwesimba regiravhiti. Huwandu hwe hydraulic pressure haina basa kuhukuru hwekusangana kwenzvimbo asi kune kudzika kwemvura kunogona kuratidzwa neiyo equation.P = ρgh. Ndiyo nzira yakajairika yekushandisa musimboti wehydrostatic pressurekuyera fluid level. Kureba sekuwanda kwemvura mumudziyo wakavharwa ichizivikanwa, sensor yepasi pemvura inogona kupa kureba kwekoramu yemvura zvichibva pakuonekwa kwekumanikidza kuverenga.
Huremu hwemhepo mumhepo yepasi redu hwakakura uye zvishoma nezvishoma zvinomanikidza pasi. Imhaka yekuvapo kwemuchadenga pressure iyo mu process measurement pressure inokamurwa mumhando dzakasiyana.
Mayunitsi ekudzvanya akasiyana zvichienderana neakasiyana dzvinyiriro masosi uye mayunitsi ehuwandu hwakakosha hwemuviri:
Pascal - Iyo SI unit yekumanikidza, inomiririra newton/㎡, umo newton iri SI unit yesimba. Huwandu hwePa imwe idiki, zvekuti mukuita kPa neMPa zvinonyanya kushandiswa.
Atm - Huwandu hweyakajairwa mamiriro ekunze, yakaenzana ne101.325kPa. Chaiyo mhepo yenzvimbo inotsikirira inochinjika kutenderedza 1atm zvichienderana nekukwirira uye mamiriro ekunze.
Bar - Metric unit yekumanikidza. 1bar yakaenzana ne0.1MPa, zvishoma zvishoma pane atm. 1 mabr = 0.1kPa. Zviri nyore kushandura unit pakati pePascal nebar.
Psi - Pounds per square inch, avoirdupois pressure unit inonyanya kushandiswa neUSA. 1psi = 6.895kPa.
Masentimita emvura - Inotsanangurwa sekumanikidza kunoitwa pasi pe 1 inch high water column. 1inH2O = 249Pa.
Mamita emvura - mH2O ndiyo yakajairika unit yekunyudza mhando yemvura level transmitter.
Different Displayed Pressure Units ( kPa/MPa/bar)
Mhando Dzekumanikidza
☆ Gauge kudzvanywa: Iyo yakajairika mhando yekuyeresa kudzvanywa kuyerwa kwakavakirwa pamhepo chaiyo yekumanikidza. Kana pasina dzvinyiriro yakawedzerwa kunze kweyakapoteredza kukosha kwemuchadenga, gauge pressure ndeye zero. Inova dzvinyiriro isina kunaka kana chiratidzo chekuverenga chiri minus, iyo kukosha kwayo kwaisazopfuura dzvinyiriro yemhepo yakatenderedza 101kPa.
☆ Kuvharirwa kudzvinyirirwa: Iyo dzvinyiriro yakabatwa mukati me sensor diaphragm inoshandisa yakajairwa mhepo yekumanikidza se base referensi point. Inogona zvakare kuve yakanaka kana yakaipa, aka overpressure uye chikamu vacuum zvichiteerana.
☆ Mhedziso kudzvinyirirwa: Kudzvanywa kwakavakirwa pane absolute vacuum kana zvese zvisina chinhu, izvo zvinogona kunge zvisingakwanisi kuwanikwa pasi pemamiriro ese akajairwa paPasi asi zvinogona kunge zviri padyo. Mhedziso yekumanikidza ndeye zero (vacuum) kana yakanaka uye haigone kuve yakaipa.
☆ Kudzvanywa kusiyanisa: Musiyano uripo pakati pekumanikidzwa kwekuyeresa madoko. Musiyano unonyanya kunaka nekuti iyo yakakwira & yakaderera kudzvanywa ports inowanzofanotemerwa zvinoenderana nedhizaini yehurongwa. Differential pressure inogona kushandiswa kuyerwa kuyerwa kwemidziyo yakavharwa uye serubatsiro kune mamwe marudzi emamita ekuyerera.
ShanghaiWangYuan, inyanzvi yekudzora magadzirirwo anopfuura makore makumi maviri inogadzira dzvinyiriro yekuyeresa zviridzwa zvinogamuchira marudzi ese ezvido zvakajairwa pamayuniti ekumanikidza uye marudzi. Zvese zvigadzirwa zvinogadziriswa zvizere uye zvinoongororwa zvisati zvabuda mufekitori. Mamodheru ane yakakosha chiratidzo anogona kugadzirisa inoratidzwa unit pamaoko. Ndapota inzwa wakasununguka kutibata nesu nezvido zvako uye mibvunzo.
