Amavalvu okulawula umshayeli we-hydraulic adlala indima ebalulekile ezinhlelweni zesimanje ze-hydraulic ngokulawula ukugeleza koketshezi nokuqinisekisa ukuphepha kokusebenza. Lawa mavalvu ahlinzeka ngokugeleza okulandela indlela eyodwa futhi avimbele ukugeleza okubuyela emuva ngaphandle kokuthi kusetshenziswa ingcindezi yomshayeli. Izimboni ezifana nezimoto kanye nezindiza ziyazamukela ngokwandayo ngenxa yokusebenza kahle kwazo ezindaweni ezinomfutho ophezulu. Ukuhlanganiswa kwezinto ezithuthukisiwe kanye nobuchwepheshe kuye kwathuthukisa ukusebenza kwazo. Isibonelo, ezinhlelweni ezifanauchungechunge lwezibambo zevalvu yokulawula umshayeli wendiza yomvukuzi, la ma-valve okulawula i-hydraulic pilot aqinisekisa ukulawula okunembile nokuthembeka. Ngaphezu kwalokho, isidingo esikhulayo se-induku yokudlala yokulawula umshayeli we-hydraulicIzixazululo emikhakheni yezimboni zigcizelela ukubaluleka kwazo ekugcineni uzinzo lwesistimu.
Izinto Ezibalulekile Okufanele Uzicabangele
- Ama-valve okushayela amanzi ahamba ngendlela eyodwa kuphela. Lokhu kumisa ukugeleza kwamanzi futhi kugcina uhlelo luphephile.
- Ukunakekela la ma-valve kubalulekile njalo. Kuzisiza ukuthi zisebenze kahle futhi zihlale ziphephile isikhathi eside.
- Lawa ma-valve enza izinhlelo zisebenze kangcono ngokulawula ukugeleza koketshezi ngqo.konga amandla amaningiemafektri.
Isebenza kanjani ivalvu yokulawula umshayeli we-hydraulic?
Isimo esizenzakalelayo kanye nokugeleza kwendlela eyodwa
A i-valve yokulawula umshayeli we-hydraulicisebenza esimweni esizenzakalelayo esivumela uketshezi ukuthi lugeleze ohlangothini olulodwa kuphela. Lokhu kugeleza kwendlela eyodwa kutholakala ngendlela efakwe entwasahlobo egcina ivalvu ivaliwe ngaphandle kokuthi kuhlangatshezwane nezimo ezithile zokucindezela. Intwasahlobo isebenzisa amandla ku-poppet yangaphakathi yevalvu, ivimbela ukugeleza okuphambene ngaphansi kwezimo ezijwayelekile. Lapho ukucindezela koketshezi endaweni yokungena kudlula amandla entwasahlobo, ivalvu iyavuleka, okwenza uketshezi ludlule.
Ithebula elingezansi libonisa ukuthi isimo esizenzakalelayo kanye nokugeleza kwendlela eyodwa kusebenza kanjani ngaphansi kwezimo zokusebenza ezahlukahlukene:
| Incazelo Yobufakazi | Incazelo |
|---|---|
| I-valve yokuhlola eyisisekelo ivumela uketshezi ukuthi lugeleze ohlangothini olulodwa, kulokhu kusukela phansi kuya phezulu. | Lokhu kubonisa umsebenzi wokugeleza kwe-valve ohamba ngendlela eyodwa, okuqinisekisa isimo sayo esizenzakalelayo sokuvimbela ukugeleza okuphambene ngaphandle kokuthi kuhlangatshezwane nezimo ezithile. |
| Isiphethu sigcina uketshezi lungagelezi ngaphandle kokuthi ingcindezi engezansi esebenza ku-poppet inqobe amandla esiphethu. | Lokhu kugqamisa indlela esebenza ngayo egcina isimo esizenzakalelayo sevalvu, okuqinisekisa ukuthi ivuleka kuphela ngaphansi kwezimo ezithile zokucindezela. |
Ngaphezu kwalokho:
- Ukucindezela emuva endaweni yokungena kuphikisana ngqo nokucindezela komshayeli, okwandisa ukucindezela okudingekayo ukuvula ivalvu.
- Ukunyakaza kwe-actuator okungajwayelekile kungase kwenzeke uma ukucindezeleka kwangemuva kuhlobene nokugeleza, okugcizelela isidingo sezimo zokusebenza eziqondile.
- Isilinganiso somshayeli osebenzayo sihlala singaphansi kwesilinganiso sendawo, okudinga ukuphathwa ngokucophelela kwengcindezi yomshayeli ukuze kusebenze kahle ivalvu.
Indima yokucindezela komshayeli ekuvuleni ivalvu
Ingcindezi yomshayeli idlala indima ebalulekileekusebenziseni ivalvu yokulawula umshayeli we-hydraulic. Uma isetshenziswa, ilwa namandla esiphethu, ivumela ivalvu ukuthi ivuleke futhi uketshezi lugeleze ngendlela ephambene uma kudingeka. Lesi sici siwusizo kakhulu ezinhlelweni ezidinga ukugeleza okulawulwayo kwezinhlangothi zombili, njengokusetshenziswa kokubamba umthwalo.
Idatha yokuhlola iqokomisa ithonya lokucindezela komshayeli ekusebenzeni kwevalvu. Isibonelo:
| Incazelo Yobufakazi | Okutholakele |
|---|---|
| Ukusebenza kwama-PRV aqhutshwa yi-pilot ngaphansi kwezimo zesidingo eziguquguqukayo | Ukucindezela komshayeli kuthonya ukusebenza kwama-valve, kuthinta ukulawulwa kwengcindezi kanye nokusabela ekushintsheni kokugeleza. |
| Ukuqhathaniswa kwesicelo sensimu phakathi kwe-PRV eqhutshwa yi-pilot kanye ne-GVS | I-GVS ikhombisa ukwehla kwezinga lokucindezela futhi igcina ingcindezi elawulwayo iseduze kakhulu nenhloso uma kuqhathaniswa ne-PRV eqhutshwa yi-pilot. |
| Ukuhlolwa kokusebenza kahle kokulawula ingcindezi | Ucwaningo luqhathanisa ukusebenza kwamavalvu okulawula azenzakalelayo ahlukene, luqokomisa indima yokucindezela komshayeli ekugcineni ingcindezi elawulwayo. |
Lokhu okutholakele kubonisa indlela ingcindezi yomshayeli eqinisekisa ngayo ukuthi ivalvu isabela kahle ezidingweni zesistimu ezahlukahlukene, okuthuthukisa ukusebenza kwayo kahle.
Indlela yokuvimbela ukugeleza emuva
Ivalvu yokulawula umshayeli we-hydraulic ifaka indlela eqinile yokuvimbela ukugeleza emuva. Le ndlela incike ku-spring-loaded poppet, evala ivalvu lapho umfutho woketshezi wehla ngaphansi kwamandla espring. Ngokwenza kanjalo, iqinisekisa ukuthi uketshezi alukwazi ukugeleza ngendlela ephambene, igcine ukuzinza kohlelo futhi ivimbele ukulimala okungenzeka ezingxenyeni.
Imibhalo yobuchwepheshe iqinisekisa le ndlela. I-hydraulic check valve isebenza njenge-valve enendlela eyodwa, ivuleka kuphela lapho umfutho woketshezi udlula amandla entwasahlobo. Lapho umfutho wehla ngaphansi kwalo mkhawulo, amandla entwasahlobo ayayivala i-valve, ivimbele ngempumelelo ukugeleza okubuyela emuva. Lo mklamo uqinisekisa ukusebenza okuthembekile ngisho nangaphansi kwezimo zokucindezela ezishintshashintshayo, okwenza kube yinto ebalulekile ezinhlelweni ze-hydraulic ezibalulekile ekuphepheni.
