Umbhobho wehydraulicisixhobo yiprojekthi ephambili yofakelo lwezixhobo zoxinzelelo lwamanzi.Umgangatho wesixhobo sombhobho yenye yezitshixo kumsebenzi oqhelekileyo wokusebenza kwenkqubo ye-hydraulic.
1. Xa kucwangciswa kunye nemibhobho, ingqwalasela ebanzi kufuneka inikwe amacandelo, amacandelo e-hydraulic, i-joint joints, kunye ne-flanges ekufuneka idibaniswe ngokusekelwe kumzobo we-hydraulic schematic diagram.
2. Ukubekwa, ukucwangciswa, kunye nesalathiso semibhobho kufuneka icoceke kwaye ixhaphake, ibe nemigangatho ecacileyo.Zama ukukhetha ukwakheka kombhobho othe tye okanye othe tye, kwaye ukungalingani kwemibhobho ethe tye kufuneka kube ≤ 2/1000;Ukungahambi ngokuthe tye kombhobho othe tye kufuneka kube ≤ 2/400.Jonga ngegeyiji yomgangatho.
3. Kufuneka kubekho umsantsa ongaphezu kwe-10mm phakathi kweenkqubo zemibhobho enxuseneyo okanye ehlanganayo.
4. Izixhobo zemibhobho ziyimfuneko ukuze kube lula ukulayishwa, ukothula, kunye nokulungiswa kwemibhobho, iivalvu zehydraulic, kunye namanye amacandelo.Naliphi na icandelo lombhobho okanye inxalenye yesistim kufuneka ikwazi ukuchithwa kwaye idityaniswe ngokukhululekileyo kangangoko ngaphandle kokuchaphazela amanye amacandelo.
5. Xa ubhobhoza inkqubo ye-hydraulic, kuyimfuneko ukuqinisekisa ukuba umbhobho unomlinganiselo othile wokuqina kunye nekhono lokuchasana ne-oscillation.Izixhaso zemibhobho kunye neeclamps kufuneka zixhotyiswe ngokufanelekileyo.Imibhobho ephothiweyo kufuneka ifakwe izibiyeli okanye iziqhoboshi ezikufutshane nendawo yokugoba.Umbhobho awusayi kudityaniswa ngokuthe ngqo kwisibiyeli okanye kwisibambiso sombhobho.
6. Icandelo lombhobho akufanele lamkelwe ngeevalvu, iimpompo, kunye namanye amacandelo e-hydraulic kunye nezixhobo;Amacandelo amacandelo anzima akufanele axhaswe yimibhobho.
7. Kuyimfuneko ukuba kuqwalaselwe iindlela eziluncedo kwimibhobho emide ukukhusela uxinzelelo olubangelwa kukutshintsha kobushushu obubangela ukwandiswa kombhobho nokuncipha.
8. Kuyimfuneko ukuba ube nesiseko esicacileyo sokuqala sombhobho osetyenziswayo, kwaye imibhobho enezixhobo ezingaziwayo ayivumelekanga ukuba isetyenziswe.
9. Imibhobho ye-hydraulic system enobubanzi obungaphantsi kwe-50mm inokusikwa ngevili lokusila.Imibhobho enobubanzi obuyi-50mm okanye ngaphezulu kufuneka iqhele ukunqunyulwa ngokwenziwa ngoomatshini.Ukuba ukusika igesi kusetyenziswa, kuyimfuneko ukusebenzisa iindlela zokucubungula ngoomatshini ukususa iindawo ezitshintshileyo ngenxa yokucwangciswa kwegesi yokusika, kwaye ngelo xesha, i-welding groove inokuguqulwa.Ngaphandle kombhobho we-oyile yokubuyisela, akuvumelekanga ukusebenzisa i-roller yohlobo lokuxova i-cutter ukusika uxinzelelo kumbhobho.Kuyimfuneko ukusika umphezulu wecala lombhobho kwaye ususe i-burrs, isikhumba se-oxide, i-slag, njl.
10. Xa umbhobho uqulunqwe ngamacandelo amaninzi ombhobho kunye nezinto ezixhasayo, kufuneka zifumaneke enye enye, igqitywe icandelo elinye, lihlanganiswe, kwaye lixhotyiswe kunye necandelo elilandelayo ukukhusela iimpazamo eziqokelelweyo emva kwe-welding enye.
11. Ukuze kuncitshiswe ilahleko yoxinzelelo oluyinxenye, icandelo ngalinye lombhobho kufuneka lithintele ukwandiswa ngokukhawuleza okanye ukunciphisa i-cross-section kunye nokujika okubukhali kunye nokujika.
12. Umbhobho oxhunywe kumbhobho odibeneyo okanye i-flange kufuneka ibe yicandelo elichanekileyo, oko kukuthi, i-axis yeli candelo lombhobho kufuneka ihambelane kwaye ihambelane ne-axis yombhobho okanye i-flange.Ubude beli candelo lomgca othe ngqo kufuneka libe likhulu okanye lilingane namaxesha ama-2 ububanzi bombhobho.
13. Indlela yokugoba ebandayo ingasetyenziselwa imibhobho enobubanzi obungaphandle obungaphantsi kwe-30mm.Xa ububanzi bangaphandle bombhobho buphakathi kwe-30-50mm, ukugoba okubandayo okanye iindlela zokugoba ezishushu zingasetyenziswa.Xa ububanzi bangaphandle bombhobho bukhulu kune-50mm, indlela yokugoba eshushu idla ngokusetyenziswa.
14. Abaweldi abawelda imibhobho esebenza ngoxinzelelo oluphezulu kufuneka babe nesiqinisekiso sesiqinisekiso sokufaneleka sokuwelda kwimibhobho yoxinzelelo oluphezulu.
15. Ukukhethwa kweteknoloji ye-welding: I-acetylene i-welding yegesi isetyenziselwa kakhulu iipayipi ezinodonga oluqhelekileyo lwe-2mm okanye ngaphantsi kwimibhobho ye-carbon steel.I-arc welding isetyenziswa ikakhulu kwimibhobho enekhabhoni yentsimbi yombhobho wodonga ubukhulu obungaphezulu kwe-2mm.Kungcono ukusebenzisa i-argon arc welding yokudibanisa imibhobho.Kwimibhobho enobunzima bodonga obungaphezulu kwe-5mm, i-argon arc welding iya kusetyenziselwa ukucoca kunye ne-Arc welding iya kusetyenziselwa ukugcwalisa.Xa kuyimfuneko, i-welding kufuneka iqhutywe ngokugcwalisa umngxuma wombhobho ngegesi yokulungisa.
16. Iintonga ze-welding kunye ne-fluxes kufuneka zihambelane kunye nempahla yombhobho odibeneyo, kwaye iimpawu zabo zorhwebo kufuneka zisekelwe ngokucacileyo kwizinto eziphathekayo, zibe nesiqinisekiso sokufaneleka kwemveliso, kwaye zibe ngaphakathi kwexesha elisebenzisekayo.Iintsimbi ze-welding kunye ne-fluxes kufuneka zomiswe ngokwemigaqo yencwadana yabo yemveliso ngaphambi kokusetyenziswa, kwaye kufuneka zigcinwe zomile ngexesha lokusetyenziswa kwaye zisetyenziswe kwangolo suku.Ingubo ye-electrode kufuneka ikhululeke ekuweni kunye nokuqhekeka okucacileyo.
17. Ukuwelda kwempundu kufuneka kusetyenziswe ukuwelda kwemibhobho eqhutywa ngamanzi.Ngaphambi kwe-welding, ukungcola, amabala e-oyile, umswakama, kunye namabala e-rust ebusweni be-groove kunye neendawo ezikufutshane kunye nobubanzi be-10-20mm kufuneka zisuswe kwaye zicocwe.
18. Iiflange zokuwelda iimpundu kufuneka zisetyenziselwe ukuwelda phakathi kwemibhobho kunye neeflange, kwaye iiflange zokugqobhoza akufanele zisetyenziswe.
19. I-butt welding kufuneka isetyenziswe kwi-welding yeepayipi kunye nokudibanisa imibhobho, kwaye i-welding yokungena akufanele isetyenziswe.
20. I-butt welding kufuneka isetyenziswe kwi-welding phakathi kwemibhobho, kwaye i-welding yokungena ayivumelekanga.
