PSIG vs PSI: Musiyano Chii: Tsananguro Iri Nyore

Munyika yeinjiniya, kugadzira, uye kudzora mvura, mazwi chaiwo ndiwo hwaro hwekuchengetedza uye kushanda zvakanaka. Kana ukashanda nehurongwa hwekumanikidza, mavharuvhu, kana mageji, ungangove wakasangana nemashoko aya.PSIuyePSIGKunyange zvazvo dzichitaridzika zvakafanana, kudzishandisa zvakafanana kunogona kukonzera zvikanganiso zvakakomba mukugadzirwa uye mashandiro ehurongwa.

Mugwaro rino, tichatsanangura musiyano uripo pakati pePSI nePSI, toongorora mashandisirwo azvo, uye totsanangura kuti sei kunzwisisa musiyano uyu kwakakosha kune chero munhu anoshanda nemasisitimu ane pressurized.

Chii chinonzi PSI?

PSIinomiriraMapaundi paSquare InchIchi chinhu chikuru chekumanikidzwa chinoshandiswa kuyera huwandu hwesimba (mumapaundi) rinoshandiswa panzvimbo imwe chete yesimbi.

Zvisinei, izwi rekuti "PSI" pacharo rinowanzo shandiswa. Nekuti kumanikidzwa kunowanzo enzanisa zvinhu zviviri, kutaura kuti "PSI" chete kunogona kusanzwisisika. Kazhinji, vanhu pavanoshandisa "PSI" muhurukuro dzisina kurongeka, vanenge vachireva kumanikidzwa kwakabatana nekumanikidzwa kwemhepo iri mumhepo—asi zviri pachena kuti iyi ingori hafu yenyaya yacho. Kuti tinyatsojeka, tinofanira kutaura kana tiri kuyera kubva mumhepo yakakwana kana kuti kubva mumhepo yakatipoteredza.

Chii chinonzi PSIG?

PSIGinomiriraMapaundi paSquare Inch GaugeUku ndiko kuverenga kwepressure kwaunoona pa standard pressure gauge.

"G" ndiyo inonyanya kukosha muchidimbu ichi. Inotsanangura kuti chiyero chacho chinoenderana nekumanikidzwa kwemhepo. Nemashoko akareruka, PSIG inokuudza kuti *kumanikidzwa* kwakawanda sei musystem kupfuura mhepo iri kusunda pairi kubva kunze.

- Nzvimbo yeZero:Pachikero chePSIG, "0 PSIG" hazvirevi kuti hapana kumanikidzwa zvachose. Asi, zvinoreva kuti kumanikidzwa kuri mukati mehurongwa kwakaenzana nekumanikidzwa kwemhepo iri kunze (inenge 14.7 PSI padanho regungwa).

- Kufananidza Kwenyika Chaiyo:Kana ukafuridza vhiri remotokari uye gauge ichiita kunge 32 PSIG, zvinoreva kuti mweya uri mukati une makirogiramu 32 pa sikweya inch *pamusoro* pesimba remhepo.

Kusiyana Kukuru Pakati pePSI nePSI

Musiyano mukuru pakati pemashoko maviri aya uri munzvimbo yekunongedzera.

> *Cherechedza: Kunyange hazvo "PSI" ichiwanzo shandiswa pakutaura, mune zvesainzi zvakanyanya, kumanikidzwa kunosanganisira mhepo yepasi kunonzi PSIA (Absolute).*

Kuti ufungidzire izvi, fungidzira pombi yakavharwa. Kana ukabvisa mamorekuru ese emhepo kuti ugadzire vacuum yakakwana, une0 PSIA(Zvechokwadi). Kana ukavhura pombi iyoyo mumhepo padanho regungwa, kumanikidzwa kuri mukati kunokwira kusvika14.7 PSIA, iyo inoverengwa se0 PSIG.

Mashandisirwo ePSI mumaindasitiri akasiyana-siyana

Kana ikashandiswa muchimiro chayo chose (chinowanzo tsanangurwa sePSIA), chiyero ichi chakakosha mukushandiswa uko shanduko mukukwirira kana mamiriro ekunze zvinogona kukanganisa maitiro acho.

1. Ndege neNdege:Ma altimeter nema cabin pressurization systems anotsigira kuverenga kwe dzvinyiriro kuti ave nechokwadi chekuti panenge pakachengeteka panzvimbo dzakakwirira.

2. Tekinoroji yeVacuum:Mumasystem akagadzirwa kugadzira vacuum, masayendisiti anoyera kuti adzika kusvika papi kubva pakumanikidzwa kwemhepo kusvika pavacuum yakakwana, iyo inoda zviyero zvekumanikidzwa zvakakwana.

3. Kurongedza Chikafu:Modified Atmosphere Packaging (MAP) inowanzo shandisa maverengero ekumanikidza akazara kuti ive nechokwadi chekuti musanganiswa wegesi wakakodzera wakavharwa mukati mepakeji pasinei nemamiriro ekunze kana kukwirira kwemiti.

4. Kuisa mufiriji yeHVAC:Nyanzvi dzemagetsi dzinoshandisa ma gauge akawanda anoverengwa muPSIG, asi kana vachiverenga kupisa kwakanyanya uye kutonhora kwepasi pesimba rekuchaja system, vanowanzo shandura kuita absolute pressure (PSIA) kuti vakwanise kufananidza thermodynamic properties nemazvo.

Mashandisirwo ePSIG mumaindasitiri akasiyana-siyana

Nekuti nyika yatinogara iri pasi pekumanikidzwa kwemhepo nguva dzose, PSIG ndiyo nzira inonyanya kushandiswa pakushandisa michina yemazuva ese. Mavharuvhu, mapombi, nemapombi zvinowanzo ongororwa muPSIG nekuti zvinofanirwa kutsungirira kumanikidzwa *kusiyana*.

1. Kugadzira Mavharuvhu:Kanavharuvhu ine kumanikidzwa kwakanyanyaSpec sheet inoratidza kumanikidzwa kwakanyanya kwe150 PSIG, zvinoreva kuti vharuvhu inogona kubata kumanikidzwa kwemukati kwe150 psi kupfuura mhepo yekunze. Dai vharuvhu iyoyo ikaendeswa pamusoro pegomo, kugona kwayo kushanda kwaizochinja, ndosaka PSIG iriyo chiyero chakajairwa.

2. Masisitimu eHydraulic:Midziyo yekuvaka, yakaita sema excavator nema lifts, inoshandisa PSIG kuyera simba re hydraulic fluid. Chiyero ichi chinoratidza kumanikidzwa kunogadzirwa ne pombi pamusoro pekumanikidzwa kwemhepo.

3. Miti Yekuchenesa Mvura:Vashandi vanoongorora PSIG kuti vaone kuti mapaipi nematangi ekusefa hazvina kumanikidzwa zvakanyanya.

4. Zvishandiso zvePneumatic:Mapanera emhepo ane simba remagetsi uye macompressor emhepo anowanikwa muPSIG. Tangi recompressor rinochengeta mweya pa100 PSIG rinochengeta mweya wakasimba ne100 psi kupfuura mweya wekunze, wakagadzirira kushanda.

Kukosha Kwekunzwisisa Kuyerwa Kwekumanikidzwa

Kune fekitori yemavharuvhu kana mutengi weindasitiri, kuvhiringa mazwi aya kunogona kudhura uye kune njodzi.

- Njodzi dzekuchengetedza:Kana vharuvhu ikapihwa 150 PSI (inodudzirwa seAbsolute), uye ukaiisa musystem inoshanda pa135 PSIG, uri kutoiisa pasi pemutemo we "roughly".149.7 PSIA(135 PSIG + 14.7 atmospheric). Unenge uchishanda zvine njodzi pedyo nenzvimbo yekukundikana.

- Kushanda Nesimba KweSisitimu:Mapombi nemacompressor anoshandisa madhigirii ekumanikidza kuti afambise mvura. Kana ukagadzira sisitimu uchishandisa manhamba akazara pawaireva manhamba ekuyera, pombi inogona kushaya simba rakakwana rekukunda kukwira kana kukweshana mumapombi.

Pfungwa Dzisiri Dzechokwadi Pamusoro pePSI nePSIG

1. PSI yakafanana nePSIG.

Izvi hazvisi zvechokwadi. Munzvimbo dzakawanda dzemaindasitiri, "PSI" inoshandiswa senzira yekutaura zvese, asi kana nhamba ichibva pachiyero che "standard dial gauge", iPSIG. Kana iri nhamba yekuverenga inosanganisira vacuums kana gasi, ingangove PSIA.

2. Kumanikidzwa kwemhepo hakuna kukosha.

Kunyange hazvo 14.7 PSI ingaita sediki kana ichienzaniswa ne3,000 PSI hydraulic system, inokosha mumasystem ane pressure shoma (senge kufefetera kana kuburitsa gasi) uye inokosha zvikuru muinjiniya ine magadzirirwo akanyatsojeka.

Maitiro Ekushandura Pakati pePSI nePSI (Absolute)

Kuti uchinje zvakarurama pakati pesimba regeji nesimba rekunze, unofanira kufunga nezvesimba remumhepo.

Fomura:

- PSIA = PSIG + 14.7(Kumanikidzwa kwemhepo padanho regungwa)
- PSIG = PSIA – 14.7

Muenzaniso:

Kana tsinga yeropa ichiratidza kuverenga kwe50 PSIGpachiyero:
- Kumanikidzwa Kwakazara (PSIA)= 50 + 14.7 =64.7 PSIA

*Cherechedza: Pabasa rakanyatsojeka kana nzvimbo dziri pakakwirira, chiyero che14.7 psi chinofanira kugadziriswa kuti chienderane nekumanikidzwa kwenzvimbo.*

Mibvunzo Inowanzo bvunzwa NezvePSI nePSIG

PSI yakafanana nePSI here?

Kwete. PSI izwi rekuti mapaundi pa sikweya inch. PSI inoreva kumanikidzwa kunoyerwa kana tichienzanisa nekumanikidzwa kwemhepo (gauge pressure). Kana mumwe munhu akati "PSI" maererano nekuverengwa kwegeji, anenge achireva PSIG nguva dzose.

Ndingashandura sei PSIG kuita PSIA?

Wedzera kumanikidzwa kwemhepo (14.7 psi padanho regungwa) kune kukosha kwePSIG. Fomura: PSIA = PSIG + 14.7.

Sei mavharuvhu achiongororwa muPSI pachinzvimbo chePSI?

Mavharuvhu anoongororwa muPSIG nekuti anofanira kutsungirira musiyano wekumanikidzwa uripo pakati pemukati mepombi nekunze kwemhepo. Musiyano uyu ndiwo unokonzera kushushikana mumuviri wevharuvhu.

Mhedziso: Kusarudza Kuyera Kudzvanywa Kwakakodzera Zvido Zvako

Kunzwisisa musiyano uripo pakati pe **PSIG nePSI** hakusi kungori nyaya dzehunyanzvi chete—chinodiwa kuti pave nekuchengetedzeka uye kunyatsoongorora mvura.

- Kana uri kutarisa gauge iri patangi, pombi, kana vharuvhu:Uri kutarisaPSIG.

- Kana uri kuita masvomhu esainzi kana kushanda nemasystem akavharwa:UnofaniraPSIA(PSI chaiyo).

At MUGADZIRI WEVHURU YENSW, tinogadzira zvigadzirwa zvedu kuti zvikwanise kumirisana nezvinodiwa zvakanyanya zvemaindasitiri chaiwo. Mareti edu ese ekumanikidzwa akanyorwa zvakajeka muPSIG kuti akubatsire kusarudza vharuvhu yakakodzera mamiriro ako chaiwo ekushanda. Kana uine mibvunzo nezve mareti ekumanikidzwa epurojekiti yako inotevera, taura nechikwata chedu cheinjiniya nhasi.
