Musiyano pakati peKuyerera kweMisa uye Kuyerera kweVolumetric

Kuyerwa kwekuyerera kwemvura muzvinhu zvakaringana mumainjiniya akasiyana uye maindasitiri mashandisirwo, ayo anovimbisa kuita kwakakwana uye kushanda nesimba. Pane mabhenefiti ari pachena kubva pakuyera kuyerera kwehuwandu kupfuura kuyerera kwevhoriyamu, kunyanya kumhepo yakamanikidzwa uye gasi rehunyanzvi senge argon, co2 nenitrogen. Verenga chinyorwa uye ugoona ruzivo rwehunyanzvi mune zvese kuyerwa.

Chii chinonzi mass flow?

Kuyerera (mass flow) zvinoreva mwero wehuwandu hunopfuura panguva imwe chete. Misa inomiririra huwandu hwese hwemamorekuru anofamba nepakati pemidziyo chaiyo, isingakanganisike nekuchinja kwetembiricha nekumanikidza. Yakasiyana nehuremu, huremu hwegasi hunoramba huri mukati kunyangwe kushanduka kwemamiriro ekunze. Kuyerera kwehuwandu hunotsanangurwa muzvikamu semakirogiramu paawa (kg/hr) kana mapaundi paminiti (lb/min); magasi anotsanangurwa muyakajairwa cubic metres paawa (Nm³/hr) kana yakajairwa cubic tsoka paminiti (SCFM).

Chii chinonzi Volumetric Flow?

Kuyerera kweVolumetric kunoreva kuyerera chaiko, kuyera vhoriyamu inofamba panguva yeyuniti. m3/hr, m3/min, CFM kana ACFM zvikamu zvakajairika zvekuyerera kwevhoriyamu, zvinoiswa kutsanangura kukura kwayakaita munzvimbo ine mativi matatu. Kuwanda kwemagasi kunoenderana zvakananga netembiricha uye kumanikidza. Huwandu hwegasi hunowedzera nekuwedzera tembiricha uye kumanikidza; pane zvinopesana, inoderera nekuderera kwekushisa uye kudzvinyirira. Mune mamwe mazwi, tembiricha uye kudzvanywa kunofanirwa kutariswa pakuyera kuyerera kwevolumetric.

Mass flow rate vs volumetric flow rate

Ruzivo rwakadzama rwehuwandu hwekuyerera uye volumetric kuyerera kweyero inobatsira kusarudza nzira yekuyera yakakodzera. Misa yekuyerera mwero ndeyechokwadi uye yakavimbika mumaitiro, umo density yemvura inogona kushanduka neiyo yekushisa nekumanikidza. Iyi tekinoroji yakakurumbira mumaindasitiri anoisa kukosha kwakawanda kune chaiyo kutonga pamusoro pezvinhu zvinoyerera, semishonga uye petrochemicals.

Pane zvinopesana, volumetric kuyerera kuyerwa kune simba rakakwana mumaindasitiri uko kurongeka kusinganyanyi kukosha. Semuenzaniso, iyo nzira inovimbika zvakakwana mukutarisa nekudzora kuyerera mune yekurima yekudiridza uye network yekugovera mvura, tisingarevi miripo yakaoma inodiwa mukugadzirisa. Volumetric iri nyore uye inodhura-inoshanda sarudzo mune chaiwo maindasitiri. Kusarurama kunogona kuitika kana mamiriro ezvakatipoteredza akasagadziriswa nemazvo.

Zvakanakira Misa Flow Measurement

Kubatsira kwekutanga kwekushandisa kuyerwa kwekuyerera kunoenderana nekurongeka kwayo uye kuvimbika, kuderedza kutsamira pane tembiricha uye kudzvanywa kwekugadzirisa. Iko kuwirirana kwakananga pakati pekuyerera kwehuwandu uye maitiro emvura inobvumira kutarisa-nguva chaiyo pasina kuoma kwekuverenga kwekubhadhara.

Sarudza kuyerwa kwekuyerera kwehuwandu hwekugadzirisa kutonga. Sarudzo dzine ruzivo dzinogona kuitwa nevashandisi vane chaiyo yekuyerera zuva ravanazvo kuderedza marara uye kuwedzera kunaka kwechigadzirwa. Kugara kutariswa kwehuwandu hwekuyerera kwemazinga kunobvumira vashandisi kugadzirisa zvinoenderana nekuchinja kwemamiriro ezvinhu, zvichisiya mashandiro ako kuti arambe achibudirira uye achishanda.

Ndeipi nguva yekushandisa volumetric kuyerera mita kana misa yekuyerera mita?

Volumetric flow metres inokurudzirwa kune maapplication anonamira kushomeka kune yakanyanya kurongeka. Zvakadaro, vhoriyamu mita inoda imwe muripo kubva kune yakawedzera tembiricha uye kumanikidza. Ipo ruzivo rwekuwedzera nezve tembiricha uye kudzvanywa kwaisakwanisa kutyisidzira pane yakakwira chaiyo uye kudzokorora. Naizvozvo, kuyerera kwemamita akanyanya kuvimbika uye kwakaringana kana achienzaniswa nevolumetric kuyerera mita.

Ndeipi nguva yekushandisa volumetric kuyerera mita kana misa yekuyerera mita?

Zvakanakira zvemass flow metres zvinomanikidza vanhu vakajaira volumetric kuyerera kwemamita kuita shanduko mune yakakosha indasitiri yekugadzirisa. Sezvineiwo, zviri nyore kupa kuyerera kwevhoriyamu ine misa yekuyerera mita, kusvika kune chinangwa nekuwedzera vhoriyamu (aka iyo pombi dhayamita) kune yekuyerera mita.

Nzira yekushandura sei kuyerera kwehuwandu kune volumetric kuyerera?

Pamwe zvinodikanwa dzimwe nguva kushandura kuyerera kwehuwandu kune volumetric kuyerera. Shanduko yacho inosvikwa mushure mekushandisa fomula yakatwasuka, uchishandisa iyo yakakosha density values ​​mune inotevera equation.

Volumetric Flow Rate=Mass Flow Rate/Density

Density inoenderana nehuwandu hwekuyerera kwehuwandu kune volumetric kuyerera. Uye density iri inversely proportional kune tembiricha uye kumanikidza. Sezvineiwo, tembiricha yakakwira inokonzeresa kushomeka uye kudzvanyirira kwakanyanya kunokonzera kuderera densities, zvakare. Thevolumetric flow rateinowanikwa nekupatsanura iyokuwanda kwekuyereranekuwanda kwemvura. Avolumetric flow rateinosiyana netembiricha uye kudzvanywa, nepo akuwanda kwekuyererainoramba iripo kana tembiricha kana kumanikidza kuchichinja.

Yakabatanidzwa kuyerera kuyerwa masisitimu ane otomatiki mhinduro anosimudzira kushanda uye kunaka kwezvigadzirwa zvekupedzisira zvakanyanya. Uyezve, kunyatso-tuning mumitengo yekuyerera uye chaiyo-nguva analytics inopa mipiro kune yakanyanya kushanda pasina kukanganisa maitiro. Iyo proactive nzira inotora mhedzisiro pane ese ari maviri akagadziridzwa mashandiro uye inoenderera mberi kuvandudzwa.

Muchidimbu, kunzwisisa nuances yekuyerera kwehuwandu uye volumetric kuyerera kuyerwa kwakakosha pakugadzirisa mashandiro mune akasiyana maapplication. Nekushandisa nzira dzekuyera dzakafanira uye nekumbundikira kusimba kwenzira yega yega, nyanzvi dzinogona kusimudzira mashandiro avo uye kuwana huroyi hwakanyanya mumagadzirirwo avo emvura.
