Chemical process applications: gwara kune yakatsiga-mamiriro uye yenguva pfupi yekumanikidza nyaya

Apo 10% yepamusoro inobvumirwa kushanda kudzvinyirira (MAWP) yakapfuura, mushandisi anogona kuzarura disc rupture kana kuti valve pressure relief valve. Kana mushandisi ari kushanda pedyo neMAWP, tapota funga kuti nekuda kwekuchinja kwepombi inverter, kusagadzikana kuyerera kwemamiriro ezvinhu uye kuwedzera kwekushisa kwevhavhavha yekudzora, kuwedzera kwemhepo, pombi yekutanga kudzvinyirira, pombi yekudzivirira kuvhara kwevhavha yekuvhara uye kuchinja kwemhepo kunogona kuitika. Danho rekutanga nderekuziva kudzvanya kwepamusoro panguva yechiitiko chakasvika MAWP. Kana mushandisi akadarika MAWP, tarisa kudzvanywa kwehurongwa 200 nguva pasekondi (mapombi mazhinji uye pombi masisitimu anotarisisa kamwe pasekondi). Iyo yakajairwa dhizaini yekumanikidza sensor haizorekodha kudzvanywa kunopfuudza 4,000 tsoka pasekondi kuburikidza nepombi system. Paunenge uchitarisa kudzvanywa pamwero we200 nguva pasekondi kurekodha kudzvanywa kunopera, funga nezve system inorekodha inomhanya avhareji mune yakatsiga mamiriro ekuchengetedza manejimendi e data data. Kana kudzvinyirirwa kuri kudiki, sisitimu inonyora avhareji inomhanya yegumi data mapoinzi pasekondi. Kumanikidza kunofanira kutariswa kupi? Tanga kumusoro kwepombi, kumusoro uye kuzasi kwevhavhavha yecheki, uye kumusoro nekudzika kwevharuvhu yekudzora. Isa dhizaini yekutarisa system pane imwe nzvimbo yakadzika kurukova kuti uone kumhanya kwemafungu uye kutanga kweiyo pressure wave. Mufananidzo 1 unoratidza pombi yekuburitsa kumanikidza kutanga kuvhiya. Iyo pombi yepombi yakagadzirirwa kuita mazana matatu emapaunzi (lbs) American National Standards Institute (ANSI), iyo yakanyanya kubvumidzwa kudzvanywa i740 pounds per square inch (psi), uye pombi yekutanga-up yekusvedzera inodarika 800 psi. Mufananidzo 2 unoratidza reverse kuyerera kuburikidza cheki valve. Iyo pombi inoshanda munzvimbo yakadzikama pakumanikidzwa kwe70 psi. Kana pombi ichidzimwa, shanduko yekukurumidza inoburitsa mafungu asina kunaka, anozoratidzwa kumashure kune yakanaka wave. Kana iyo yakanaka wave ichirova cheki chevhavha disc, cheki vharafu ichiri kuvhurika, zvichiita kuti kuyerera kudzokere kumashure. Kana iyo cheki valve yakavharwa, kune imwe yekukwira kumusoro uye ipapo ine negative pressure wave. Kudzvanywa kwepombi system kunodonha kusvika -10 pounds per square inch geuge (psig). Iye zvino izvo zvinodzvinyirira zvinopera zvakarekodhwa, danho rinotevera nderekuenzanisira mapombi uye pombi masisitimu kutevedzera shanduko yekumhanya inoburitsa zvinoparadza zvinomanikidza. Surge modelling software inobvumira vashandisi kuisa pombi curve, saizi yepombi, kukwirira, dhayamita yepombi uye pombi zvinhu. Ndezvipi zvimwe zvikamu zvepombi zvinogona kuburitsa kukurumidza shanduko muhurongwa? Surge modelling software inopa akatevedzana evharuvhu maitiro anogona kutevedzerwa. Komputa yenguva pfupi yekuenzanisira software inobvumira vashandisi kutevedzera imwe-chikamu kuyerera. Funga nezve mukana wekuyerera kwezvikamu zviviri zvinogona kuzivikanwa nekukasira kudzvanywa kwekutarisa mukushandisa. Pane cavitation mupombi uye pombi system? Kana hongu, inokonzerwa nepombi yekusveta kudzvanywa kana pombi yekuburitsa kumanikidza panguva yerwendo rwepombi? Kushanda kwevharuvhu kuchaita kuti kukurumidza kwepiping system kuchinje. Paunenge uchishanda valve, kukwira kwepamusoro kuchawedzera, kuderera kwepasi kuchaderera, uye mune dzimwe nguva cavitation ichaitika. Mhinduro iri nyore yekumanikidza kuchinja inogona kunge iri kuderedza nguva yekushanda paunenge uchivhara valve. Mushandisi ari kuedza kuchengetedza chiyero chekuyerera nguva dzose kana kumanikidza? Iyo nguva yekutaurirana pakati pemutyairi nepressure transmitter inogona kuita kuti sisitimu itsvage. Pachiito chega chega, pachave nekuita, saka edza kunzwisisa mafambiro anopfuudza kuburikidza nekumhanya kwemafungu. Kana pombi ichiwedzera, kudzvanywa kunokwira, asi iyo yakanyanya kudzvanywa wave icharatidzwa kumashure seyakaipa yekumanikidza wave. Shandisa high frequency pressure monitoring kugadzirisa madhiraivha ekudzora mota uye mavharuvhu ekudzora. Mufananidzo 3 unoratidza kusagadzikana kudzvinyirira kunogadzirwa neiyo variable frequency drive (VFD). Kudzvinyirira kwekubuda kwakashanduka pakati pe204 psi uye 60 psi, uye s742 pressure fluctuation chiitiko chakaitika mukati 1 awa uye 19 maminetsi. Kudzora vharafu oscillation: The shock pressure wave inopfuura nemuvharuvhu yekudzora isati yapindura kune shock wave. Flow control, back pressure control uye pressure yekudzikisa valve zvese zvine nguva yekupindura. Kuti upe uye ugamuchire simba, pulsation uye midziyo yekuvhiya inoiswa kune buffer shock waves. Paunenge uchitarisa saizi ye pulsation damper uye tangi yekuvhiya, zvakakosha kuti unzwisise mamiriro akatsiga uye hushoma uye huwandu hwemafungu ekumanikidza. Kuchaja kwegasi uye gasi vhoriyamu inofanira kunge yakakwana kutarisana nekushanduka kwesimba. Gasi uye chiyero chemvura chiverengero chinoshandiswa kusimbisa pulsation dampers uye buffer midziyo ine multivariable constants ye1 panguva yakadzikama uye 1.2 panguva yenguva pfupi yekumanikidza zviitiko. Mavharuvhu anoshanda (akavhurika/akavhara) uye cheki mavharuvhu (padhuze) ndiwo akajairika shanduko mukumhanya kunokonzera kutarisa. Kana pombi ichidzimwa, tangi yebhafa yakaiswa pasi pemvura yevharuvhu yekutarisa ichapa simba rekumhanya kweinflation. Kana pombi ikamhanya kubva pakona, kumanikidzwa kwemusana kunoda kugadzirwa. Kana mushandisi akasangana nekudzvinyirirwa kwekuchinja kubva kumashure ekumanikidza control valve, iyo system ingangoda kuisa pulsation damper kumusoro. Kana vharuvhu yakavhara nekukasira, ita shuwa kuti gasi vhoriyamu yedhishi inodzora mudziyo inogona kugamuchira simba rakakwana. Ukuru hwevhavha yekuongorora hunofanira kugadziriswa maererano nehuwandu hwekuyerera, kudzvinyirira uye urefu hwepombi yepombi kuti ive nechokwadi chekuvhara nguva yakakodzera. Mapombi akati wandei ane cheki mavharuvhu akawandisa, akavhurika zvishoma uye oscillate mukuyerera kwerukova, izvo zvinogona kukonzera yakawandisa vibration. Kududzira zviitiko zvekudzvinyirira zvakanyanya mune yakakura process pombi network inoda akawanda ekutarisa mapoinzi. Izvi zvichabatsira kuona kunobva kudzvinyirira wave. Iyo yakaipa pressure wave inogadzirwa pazasi pemhepo yekumanikidza inogona kuve yakaoma. Iwo maviri-chikamu kuyerera kwegasi kumhanyisa kukwirisa uye kudonha kunogona kurekodhwa kuburikidza nechinguvana kudzvanywa kwekutarisa. Iko kushandiswa kweinjiniya yeforensic kuwana chikonzero chekuchinja kwekudzvanya kunotanga nekutarisa kwenguva pfupi.
