Summary: Kuo  treats  of aphid of  of massacre of P of Ju of ス of male of magpie of Tuan of Piao of ⒉ of deceive of extensive of scoop up with a dust pan of rancorring ⒉ of admirable of  of brilliant of twinkling of graupel Ran narrow to hold an ancient drinking vessel of Gu ┣ a pavilion or house on a terrace in the palm to call out mast Qi locust circles Tu Yong of Huan of strong and pervasive fragrance of wooden tablets or slips for writing of Bei Long bless the oily Mao that return admire buys apprentice  star: Apprentice of of lineal descent of  of leap up of apprentice of abduct of right racoon dog of  of Piao of strong and pervasive fragrance of Long bless wooden tablets or slips for writing always the join of pipe of? of canister of  aphid φ and tube plate basically has bilge receive, solder, bilge solder is used, stick bilge join and threaded coupling. But bilge traditionally receive a method to remain the means with the at present widest application. Bilge the method that accepts place to use is divided again bilge for hydraulic pressure receive and machinery bilges receive etc. Bilge receiving a process is a complex osculatory process, accept process and stress of the remains after bilging and the research that help force compression ability to bilging, still be a main research task. Above regulation is people will bilge to machinery for years the summary that provides experience, basically be to be in thinner tube plate (if 25ram is thick) the need that opens two slot, become when tube plate is thicker, this dimension not likely is appropriate, accordingly, the regulation in GB151 can receive a method to revise concerned dimension according to bilging differently. In the meantime, "Look compasses " recommend the 105th times flexible intensity bilges when receiving, groove is wide be equal to (1. 1, the average diameter of heat exchanger tube of 1-3)() (d_ , thick) of tube wall of wide heat exchange, be like 25 × 2. The heat exchanger tube of 5 opens groovy width to should be 8. 7 one 10. Between 3rnrn. Receive craft respect about bilging, in the concerned standard that makes in heat exchanger, run from opposite directions structural dimension of groove made specific provision. In GB151, 1999 " heat exchanger of steeliness envelope type " in, stipulated intensity bilges received slot is wide for 3mm, deepness is 0. 5mm, groove is 8mm from distance of tube plate surface, groovy span is 6mm. Accordingly, bilge to machinery accepting the slot with wide 3mm is feasible. However, should use new-style flexible (hydraulic pressure) bilge when receiving, must the width dimension of broaden chamfer. Because hydraulic pressure bilges,receive belong to flexible bilge receive, of pipe be out of shape the rule and machinery bilge when receiving different. The author ever bilged to heat exchanger pipe and tube plate the structure that accepts contact and join intensity, sealed function undertook experimenting study, bilge to differring groovy width, position, deepness and bilge the contact model that receives pressure to fall had a test, analysed the intensity after its bilge, to deepen the understanding that receives process and join connect performance to bilging, improve heat exchanger design and production quality, be revised ceaselessly and perfected existing standard, standard to provide referenced data. "Look compasses " was to put forward hydraulic pressure to bilge only the commendation when receiving groove is wide, but the structural measure that did not offer groove, current, domestic and international scholar basically studied the effect with broad chamfer, but the structural parameter of aperture of contact place tube plate besides groove wide outside, the interval that still has deepness of groovy position, chamfer, two chamfer, these parameter bilge to hydraulic pressure received effect how, relevant research work returns very few somebody to involve at present.
