I-hydraulici-valve elinganayo enekhadi le-amplifieriyingxenye ebalulekile ohlelweni lwe-hydraulic ukulawula ngokunembile ukugeleza koketshezi kanye nokucindezela.Lesi sihloko sihlose ukufunda kabanzi mayelana nokuthi iyini i-proportional valve amplifier nokuthi isebenza kanjani ngokuhambisana ne-hydraulic proportional valve.
Amasistimu we-hydraulic adlala indima ebalulekile ezimbonini ezahlukahlukene ezihlanganisa ezokukhiqiza, ezezimoto kanye ne-aerospace.Lezi zinhlelo zisebenzisa ama-valve angama-hydraulic ukulawula ukugeleza nokuqondiswa koketshezi futhi ekugcineni ukunyakaza kwezingxenye zemishini.Ama-valve alinganiselayo aklanyelwe ukunikeza ukulawula okunembile nokushelelayo kokugeleza koketshezi nokucindezela.
Njengoba igama lisho, i-proportional valve amplifier ikhulisa isignali yokulawula etholwe kudivayisi yomyalo noma inzwa futhi inquma ukusebenza kwe-valve yokulinganisa.Isebenza njengebhuloho phakathi kwesignali yomyalo kanye ne-valve ye-proportional, iqinisekisa ukulawulwa kokulingana okunembile kwesistimu.Ikhadi le-amplifier ibhodi lesekethe ye-elekthronikhi elithatha isignali yokufaka futhi likhiqize isignali ephumayo ekhulisiwe ukuze ishayele i-valve yokulingana.
Umgomo wokusebenza we-hydraulici-valve elinganayo enekhadi le-amplifierukushintsha usayizi wokuvula we-valve ngokusho kwesignali yokulawula kagesi.Ikhadi le-amplifier lithatha isignali yomyalo (imvamisa isesimweni se-voltage noma yamanje) futhi iyiguqule ibe isignali yamanje ekhulisiwe eshayela i-valve elinganayo.Le signali ekhulisiwe ilawula indawo ye-spool ye-valve, yona elawula ukugeleza koketshezi.
Ama-valve amplifiers alinganiselayo anika amandla ukulawula okunembile ngokunikeza ubudlelwano bomugqa phakathi kwesignali yomyalo nokuphuma kwe-valve.Isibonelo, ukukhuphuka okungu-50% kusiginali yomyalo kubangela ukwanda okungama-50% kokugeleza koketshezi.Leli zinga lokulawula libalulekile ezinhlelweni zokusebenza ezidinga ukulawulwa okunembile kokulingana kokugeleza koketshezi noma ukucindezela, okufana nezimboni ezishintshayo kanye nezinhlelo zokulawula ukunyakaza.
Njengesisetshenziswa se-elekthronikhi, ikhadi le-amplifier nalo linezinzuzo eziningi kunezinhlelo zokulawula ze-analog zendabuko.Inikeza ukwethembeka okuthuthukisiwe, ukuphindaphinda kanye nokuguquguquka ekucubunguleni isignali.Amakhadi esikhulisi sesimanje ngokuvamile aqukethe ama-microprocessors wemisebenzi ethuthukisiwe efana nesimo sesignali, ukuxilonga, nemisebenzi yokuxhumana.
Inhlanganisela yama-hydraulic proportional valves kanye namakhadi we-amplifier inikeza izinzuzo eziningana kumasistimu asebenza ngamanzi.Okokuqala, inika amandla ukulawulwa okunembile kokugeleza kwamanzi nokucindezela, ukuthuthukisa ukusebenza kwesistimu nokusebenza kahle.Okwesibili, inika amandla ukusebenza okushelelayo, okuphendulayo ngokuphazanyiswa okuncane nokudlidliza.Okokugcina, kusiza ukulawula okude kanye ne-automation, ikwenze ifanele izinhlelo eziyinkimbinkimbi noma izinhlelo zokusebenza ezidinga ukusebenza okukude.
Ngamafuphi, i-hydraulici-valve elinganayo enekhadi le-amplifieriyingxenye eyinhloko ohlelweni lwe-hydraulic olunikeza ukulawula okunembayo kokugeleza koketshezi nokucindezela.Ama-valve amplifier adlala indima ebalulekile ekuguquleni amasiginali womyalo abe yi-proportional actuation yama-valve.Inikeza ukulawula okunembile, ukwethembeka kanye nemisebenzi eyengeziwe ngokusebenzisa amasekethe kagesi.Ukuhlanganiswa kwalezi zingxenye kuletha izinzuzo eziningi ohlelweni lwamanzi, okulwenza lufanelekele uhla olubanzi lwezinhlelo zokusebenza kuzo zonke izimboni ezihlukahlukene.
