Incwadi Yokusebenza Yesistimu Yokuhlola Ukumelana Ne-Acid Ne-Alkali Yezingubo Zokuvikela ze-YYT-T453
Leli thuluzi lisetshenziselwa ukuhlola ukumelana kwengcindezi ye-hydrostatic kwezingubo zokuvikela indwangu ngamakhemikhali e-asidi nama-alkali. Inani lengcindezi ye-hydrostatic yendwangu lisetshenziselwa ukuveza ukumelana kwe-reagent ngendwangu.
1. Umgqomo wokufaka uketshezi
2. Idivayisi yesampula yokubamba
3. Ivalvu yenaliti yokukhipha amanzi ewuketshezi
4. I-beaker yokubuyisa uketshezi olungcolile
Isithasiselo E se-"GB 24540-2009 Izingubo Zokuvikela Izekhemikhali Ezisekelwe ku-asidi"
1. Ukunemba kokuhlolwa: 1Pa
2. Ububanzi bokuhlola: 0～30KPa
3. Imininingwane yesampula: Φ32mm
4. Ukunikezwa kwamandla: AC220V 50Hz 50W
1. Ukusampula: Thatha amasampula amathathu ezingutsheni zokuzivikela eziqediwe, usayizi wesampula ungama-φ32mm.
2. Hlola ukuthi isimo sokushintsha kanye nesimo sevalvu kujwayelekile yini: inkinobho yamandla kanye nenkinobho yokucindezela kusesimweni sokungasasebenzi; ivalvu elawula ukucindezela iphendukelwe ngakwesokudla esimweni sokungasasebenzi ngokuphelele; ivalvu yokukhipha amanzi isesimweni sokuvaleka.
3. Vula isivalo sebhakede lokugcwalisa kanye nesivalo sesibambi sesampula. Vula inkinobho yokuvula.
4. Thela i-reagent elungiselelwe kusengaphambili (i-80% sulfuric acid noma i-30% sodium hydroxide) kancane emgqonyeni wokufaka uketshezi kuze kube yilapho i-reagent ivele endaweni yokubamba isampula. I-reagent emgqonyeni akumele idlule umgqomo wokufaka uketshezi. Ama-stomata amabili. Qinisa isivalo sethangi lokugcwalisa kabusha.
5. Vula iswishi yokucindezela. Lungisa kancane ivalvu yokulawula ukucindezela ukuze izinga loketshezi esibambini sesampula likhuphuke kancane kuze kube yilapho ubuso obuphezulu besibambi sesampula bulingana. Bese ubopha isampula elungisiwe esibambini sesampula. Qaphela ukuthi ubuso besampula buthintana ne-reagent. Uma ubopha, qiniseka ukuthi i-reagent ngeke ingene esampula ngenxa yokucindezela ngaphambi kokuba kuqale ukuhlolwa.
6. Sula ithuluzi: Kumodi yokubonisa, akukho ukusebenza kokhiye, uma okokufaka kuyisignali engu-zero, cindezela «/Rst imizuzwana engaphezu kwemi-2 ukuze usule iphuzu elingu-zero. Ngalesi sikhathi, isibonisi singu-0, okungukuthi, ukufundwa kokuqala kwethuluzi kungasulwa.
7. Lungisa kancane ivalvu elawula ingcindezi, cindezela isampula kancane, njalo, futhi kancane kancane, bheka isampula ngasikhathi sinye, bese uqopha inani lengcindezi ye-hydrostatic lapho kuvela ukwehla kwesithathu kusampula.
8. Isampula ngayinye kufanele ihlolwe izikhathi ezi-3, futhi kufanele kuthathwe isilinganiso sezibalo ukuze kutholakale inani lokumelana nengcindezi ye-hydrostatic yesampula.
9. Cima iswishi yokucindezela. Vala ivalvu yokulawula ingcindezi (jika ngakwesokudla ukuze uvale ngokuphelele). Susa isampula evivinyiwe.
10. Bese wenza isivivinyo sesampula yesibili.
11. Uma ungaqhubeki nokwenza isivivinyo, udinga ukuvula isembozo sebhakede lokulinganisa, uvule ivalvu yenaliti ukuze kukhishwe amanzi, ukhiphe amanzi ngokuphelele ku-reagent, bese ugeza ipayipi ngokuphindaphindiwe nge-ejenti yokuhlanza. Akuvunyelwe ukushiya insalela ye-reagent ebhakedeni lokulinganisa isikhathi eside. Isampula yedivayisi ye-clamp kanye nepayipi.
1. Kokubili i-asidi ne-alkali kuyagqwala. Abasebenzi bokuhlola kufanele bagqoke amagilavu angangenwa yi-asidi/alkali ukuze bagweme ukulimala komuntu.
2. Uma kwenzeka into engalindelekile ngesikhathi sokuhlolwa, sicela ucime amandla ethuluzi ngesikhathi, bese ulivula futhi ngemva kokususa iphutha.
3. Uma ithuluzi lingasetshenziswa isikhathi eside noma uhlobo lwe-reagent lushintshiwe, umsebenzi wokuhlanza ipayipi kumele wenziwe! Kungcono ukuphinda ukuhlanza nge-ejenti yokuhlanza ukuze uhlanze kahle ibhereli yokulinganisa, isibambi sesampula kanye nepayipi.
4. Akuvunyelwe nhlobo ukuvula inkinobho yokucindezela isikhathi eside.
5. Ukunikezwa kwamandla kwethuluzi kufanele kusekelwe ngokuqinile!
