Steam Turbine Eh oy System Servo Valve 072-559A

Incazelo emfushane:

I-Electrohydraulic Servo Valve 072-559A iyingxenye ebalulekile yohlelo lwe-Hydraulic Servo. Kuyi-Hydraulic control valve eqhubeka ilawula ngokuqhubekayo ukugeleza nokucindezela ngokwengeziwe ngokushintsha amasiginali wokufaka. Ubungako obuncane bokugeleza kwe-nozzle valve cishe ngo-0,2 mm, kuyilapho usayizi omncane wokugeleza kwe-nozzle anzle servo valve ngu-0.025 ~ 0.10 mm. Ngakho-ke, i-nozzle inekhono eliqinile lokulwa nokungcola, ukuthembeka okuphezulu, kanye nempilo yenkonzo ende. Ikhono lokulwa nokungcoliswa kwama-servo valves ngokuvamile linqunywa yinani elincane lokugeleza esakhiweni sabo. Kodwa-ke, emavazwini e-Multistage Servo, usayizi omncane kakhulu esifundeni samafutha esiphambili uba yinto enqumayo.

Imininingwane Yomkhiqizo

Imbuyiselo

I-ElectrohydraulicI-servo valveI-072-559A inokusebenza kahle kwengcindezi kanye nokusebenza kahle kwe-volumetric, okungakhiqiza ingcindezi yokulawula okukhulu nokugeleza, ukwenza ngcono amandla okushayela kanye nekhono lokulwa nokungcoliswa kwe-valve yamandla. Ngokombono womthelela wokugqoka kwangaphambili ekusebenzeni, ukugqokwa kobuso bokuphela kwe-nozzle kanye nobuso bokuphela kwe-electro-hydraulic servo Valve kunomthelela omncane ekusebenzeni, okuholela ekusebenzeni kwezinsizakalo, kanye nempilo yenkonzo ende.

Umgomo Wokusebenza

Isiginali ye-Electrical Command (I-Flow Rate Set Point) isetshenziswa kumakhoyili e-torque motor, futhi yakha amandla kazibuthe asebenza emaphethelweni esiteji sezindiza. Lokhu kubangela ukungcola komhlangano we-armature / weflappper ngaphakathi kweshubhu le-flexire. Ukuhlanekezelwa kwe-Flapper kuvimbela ukugeleza koketshezi ngokusebenzisa i-nozzle eyodwa ephethwe endaweni eyodwa ye-spool, okususa i-spool.

Ukuhamba kwe-spool kuvula i-Supply Pressure Port (P) kwi-Port One Control Port, ngenkathi ngasikhathi sinye ukuvula iTank Port (T) kwelinye itheku lokulawula. Ukunyakaza kwe-spool nakho kusebenza ngamandla entwasahlobo ye-cantilever, kwakha i-torque yokubuyisela kabusha emhlanganweni we-armature / Flapper. Lapho nje ukubuyiswa
UTorque ulingana ne-torque evela kumandla kazibuthe, umhlangano we-armature / we-flapper ushukumisela emuva endaweni yokungathathi hlangothi, futhi i-spool iphelelwe obala ngesimo sokulingana kuze kube yilapho kushintsha isignali esisha.

Ngamafuphi, isikhundla se-spool silingana nokufakwa kwamanje futhi ngokuthobeka kwengcindezi njaloisivalwana; Ukugeleza komthwalo kulingana nesikhundla se-spool.
