Iintlobo zeHydraulic Bellows
Umbhobho we-Hydraulic corrugated pipe ngumbhobho wokutywina oguquguqukayo onokwandiswa kwaye ugobe, odla ngokwenziwa ngeeleya ezininzi zesinyithi (okanye-iipholima zokusebenza eziphezulu) ngokuchaneka kwe-welding okanye ukuqulunqwa kweenkqubo, ukwenza isheyiphu yokumila. Umsebenzi wayo ophambili kukuseka umjelo otywiniweyo ngokupheleleyo kunye nokuvuza kwasimahla phakathi kwezinto ezisisigxina nezishukumayo ukulungiselela iintshukumo ezintsonkothileyo.
Imibhobho yeHydraulic inikwa amandla ziisilinda zehydraulic kwaye ulawulo lolwelo luphunyezwa ngemivumbo okanye imisesane yokutywina. Ngokomzekelo, kuyilo lwevalve, iibhobho ezithathiweyo zisetyenziswa njengezinto zokutywina kwaye ziqhutywa ngamasilinda e-hydraulic ukufikelela kwizenzo zokutshintsha. Kuthungelwano ngoomatshini, iintsimbi zehydraulic zinokuthatha indawo yezixhobo zemveli zokuhambisa oomatshini, ukunciphisa ubunzima bokusebenza, kunye nokwandisa ubomi benkonzo.

Iiparamitha eziphambili zobugcisa (izalathi eziphambili zokukhetha)
Xa ukhetha imibhobho ye-hydraulic corrugated, ezi parameters zilandelayo kufuneka zinikwe ingqwalasela eyodwa ukuqinisekisa ukuhambelana nenkqubo ye-hydraulic:
Uxinzelelo Lokusebenza:Ibhekisa kuxinzelelo oluphezulu lwehydraulic olunokuthi imivumbo imeme ngexesha-lokusebenza kwexesha elide. Kufuneka ibe yi-1.2 ukuya ku-1.5 amaxesha amakhulu kunoxinzelelo lwangempela lokusebenza lwenkqubo (into yokhuseleko) ukukhusela ukuphulwa koxinzelelo.
Ubushushu bokusebenza:Ikhethwe ngokusekelwe kwiqondo lokushisa eliphakathi kunye nobushushu be-ambient. Intsimbi yentsimbi ikholisa ukugquma ubushushu obuphakathi kwe - 200℃ukuya 600℃(ukuya kwi 1000℃for high-temperature alloys), lo gama imivumbo yeplastiki igquma ubukhulu becala iqondo lobushushu elingama -40℃ukuya kuma 80℃.
Imali yembuyekezo yokufuduswa:Ibandakanya isixa sembuyekezo ye-axial (ubude obuninzi benguqu ye-tension / compression), isixa sembuyekezo yecala (umgama ophezulu we-lateral offset), kunye nexabiso lembuyekezo ye-angular (i-Angle ephezulu yokuphambuka), ekufuneka ibe mkhulu kuneyona mali yokufuduka eyenziwe yinkqubo.
Ukuhambelana nemidiya:Qinisekisa ukuba izinto zombhobho obhityileyo azenzeki kwiikhemikhali kunye ne-hydraulic medium (efana ne-oyile ye-mineral, i-synthetic hydraulic oil, amanzi{0}}isisombululo se-ethylene glycol), kwaye unqande ukubola okanye ukuguga kwezinto (umzekelo, i-carbon steel ayinakusetyenziswa emanzini{1}}based hydraulic fluid).
Idayamitha yoMzimba:Ihambelana nobubanzi bangaphakathi bombhobho, ngokuqhelekileyo ukusuka kwi-DN6 ukuya kwi-DN500 (ukwenziwa ngokwezifiso kuyafuneka kwii-diameters ezinkulu), kwaye kuchaphazela ukuhamba kunye nokulahlekelwa koxinzelelo.
Ubomi bokudinwa:Ibhekisela kwinani lemijikelezo yokuguqulwa kwe-deformation enokuthi i-bellows ikwazi ukumelana phantsi koxinzelelo olulinganisiweyo kunye nokufuduka (ngokuqhelekileyo kufunwa ukuba ibe Mkhulu okanye ilingane namaxesha angama-10,000, kunye nezixhobo zoshishino, Inkulu okanye ilingana namaxesha e-100,000). Ubomi obungonelanga buya kukhokelela ekuqhekekeni kwangoko.
