Ukusetyenziswa kweVortex Flowmeter kuMlinganiselo weBiogas

2020-10-17
I-vortex flowmeterisekelwe kumgaqo we-karman vortex. Ibonakaliswa ikakhulu njenge-non-streamline vortex generator (i-bluff body) isetilwe kulwelo oluqukuqelayo, kwaye imiqolo emibini ye-vortices eqhelekileyo yenziwa ngokutshintshana ukusuka kumacala omabini ejeneretha ye-vortex. Isetyenziswa kakhulu kwi-petroleum, ikhemikhali, i-metallurgical, i-thermal, i-textile, iphepha kunye namanye amashishini obushushu obuphezulu, umphunga ogcweleyo, umoya ocinezelweyo kunye neegesi eziqhelekileyo (ioksijini, initrogen, ihydrogen, igesi yendalo, igesi yamalahle, njl.njl.), amanzi kunye ulwelo (njengamanzi, ipetroli, njl.njl.) Utywala, benzene, njalo njalo) umlinganiselo kunye nolawulo.

Ngokubanzi, umyinge wokuhamba kombhobho wegesi yebhayoloji umncinci, kwaye ulinganiswa ngokubanzi ngokunciphisa ubukhulu. Sinokukhetha iintlobo ezimbini zesakhiwo, uhlobo lwekhadi le-flange kunye nohlobo lwe-flange. Xa ukhetha uhlobo, kufuneka sikhethe ukuqonda isantya esincinci sokuhamba, izinga lokuhamba okuqhelekileyo kunye nesantya esikhulu sokuhamba kwe-biogas. Uninzi lweendawo zokulinganisa i-biogas azinawo umthombo wamandla, ngoko ke sinokukhetha i-vortex flowmeters enebhetri. Ukuba umsebenzisi ufuna ukwazisa umboniso wemitha ngaphakathi, i-vortex flowmeter edibeneyo ingasetyenziswa, kwaye umqondiso wokuphuma ukhokelwa kwi-totalizer ehambayo efakwe kwigumbi ngentambo. I-Vortex flowmeter inokubonisa ukuhamba okukhawulezileyo kunye nokuhamba okunyukayo kwe-biogas.
Xa ufaka i-vortex flowmeter ukulinganisa i-biogas, ukuba i-valve ifakwe kufuphi nomphezulu wendawo yokufakela, kwaye i-valve ivuliwe rhoqo kwaye ivaliwe, iya kuba nefuthe elikhulu kubomi benkonzo yenzwa. Kulula kakhulu ukwenza umonakalo osisigxina kwinzwa. Kuphephe ukufaka imibhobho engaphezulu kakhulu emide kakhulu. Emva kwexesha elide, ukuthoba kwenzwa kuya kubangela ukuvuza kokutywinwa phakathi kwenzwa kunye neflange. Ukuba kufuneka uyifake, kufuneka ufakele umbhobho kumsinga onyukayo kunye nosezantsi kwe-2D yenzwa. Isixhobo sokuqinisa.

Ukuqinisekisa ukusebenza okupheleleyo, iphethini yokuhamba emnyango akufanele iphazamiseke. Ubude becandelo lombhobho othe ngqo onyukayo kufuneka bube malunga namaxesha ali-15 kwi-flowmeter idayamitha (D), kwaye ubude becandelo lombhobho othe tye osezantsi kufuneka bube malunga nokuphindwe ka-5 kwi-flowmeter diameter (D). Xa isandi se-vortex esingeyo-streamline sisetwa kulwelo, imiqolo emibini yee-vortices eziqhelekileyo zenziwe ngokutshintshanayo ukusuka kumacala omabini e-vortex. Le vortex ibizwa ngokuba sisitalato saseKarman vortex. Kuluhlu oluthile lokuhamba, i-vortex yokwahlula i-frequency ilingana nomyinge wesantya sokuhamba kumbhobho. I-capacitance probe okanye i-piezoelectric probe (i-detector) ifakwe kwi-vortex generator kwaye isiphaluka esihambelanayo siqulunqwe ukuba senze ukufunyanwa kwe-capacitance.I-vortex flowmeterokanye Piezoelectric ubhaqo uhlobo lokuqukuqela isivamvo vortex.
