Daim ntawv thov thiab qhov zoo ntawm tooj dag raj hauv engineering machinery
Brass tubes yog siv los ua cua sov coils rau condensers thiab coolers thiab raj rau kev siv dav. Cov raj tooj dag yog ua los ntawm cov qib tooj dag hauv qab no (raws li POGT 1019-47): 68 thiab 70 tooj dag rau cov condensers, thiab 62 tooj dag rau kev siv cov raj txias txias nrog ib txoj kab uas hla ntawm 3 mus rau 100 cm. Lub raj ntev yog 1-6 meters.
Cov raj rau condensers-coolers thiab lwm yam khoom siv hluav taws xob hloov pauv yuav tsum raug ntsuas hydraulic siab ntawm 50 kg / cm2 rau lub sijhawm sim tsis pub tsawg tshaj 10 vib nas this.
Hom kev sib hloov hluav taws xob no, uas tau siv tsis ntev los no, muaj qhov zoo hauv qab no piv rau lub plhaub thiab lub raj cua kub exchangers:
1. High heat transfer coefficient, uas yog vim qhov siab khiav ceev, turbulence thiab tiav countercurrent;
2. Cov khoom hnyav uas yuav tsum tau rau chav tsev hloov hluav taws xob yog me me;
3. Kev them nyiaj zoo rau qhov kub thiab txias deformation;
