Mu Steam Turbine Digital Electro-Hydraulic Controls (Deh), electro-hydraulicserva valaG771k208 ndiye gawo loti mukwaniritse. Imaperekanso maumboni kudzera pa LVDT kuti muwonetsetse kulondola komanso kukhazikika kwa kusintha kwa matiki. Nkhaniyi ifotokoza momwe servo valve g771k208 imatha kugwiritsa ntchito bwino kwambiri malingaliro a mfundo za mfundo za gawo la Ndege, Kutumiza Kotseka, Zotseka Zotseka, Ndi Zina

1. Kapangidwe kake ndi ntchito ya servo vala g771k208

Servo Valve G771k208 imatengera zowotchi zolimba + ziwiri zowonjezera. Zigawo zikuluzikulu zimaphatikizapo coil yamagetsi, yabalalika, yosavuta, phokoso ndi slideve ndi slideve. Pamene oyang'anira a deh akamatumiza magetsi, chilengedwe cha electromagnetic chimatulutsa maginito, chimayendetsa chimamba kuti chiletse ndikuyendetsa bofle kuti musunthe. Kusintha kwa kusiyana pakati pa boffle ndipo nozzelles mbali zonsezi kumapanga kusiyana kwakukulu, kanikizani valavu yomwe imasamutsidwa, ndikuwongolera mafuta osakanikirana ndi mafuta.

Zofunikira:

1. Kukhuta kwa Torque: Kupanga kwa madambo ndi kogwirizana ndi zomwe zafotokozedwazi ndi zomwe zachitika pano, ndipo kusinthana kumatha kufikira 0.1%, ndikuwonetsetsa kuthekera kwabwino.

2. Njira yokhazikika ya LVDT valavu

1. Kukhazikitsa mwakuthupi ndi kuyika m'badwo wa LVDT

Piston ya Mafuta ya servo Valve g771k208 imalumikizidwa ndi valavu yowongolera kudzera mu ndodo yolumikizira. LVDT imakhazikitsidwa mwachindunji nyumba yamafuta, ndipo maziko ake achitsulo amalumikizidwa ndi ndodo ya piston. Piston ikasuntha, udindo wa LVDT Chitsulo Kusintha Kwachitsulo, zomwe zimapangitsa kuti zisinthe m'mataneti oyambira limodzi ndi zigawo ziwiri zachiwiri, ndipo K ndi zomwe zimapangitsa).

Malangizo:

- Malo a LVDT zero amayenera kukhala ogwirizana ndi malo otsekeka kwathunthu a mota, ndipo kupatuka kumayenera kulamulidwa mkati mwa ± 0.mm.

- Kuuma kwa bulangeki kumafunikira kukwaniritsa pafupipafupi> 100hz kuti mupewe kusokonekera kwamakina.

2. Kuwongolera kulembetsa ndi chotseka chotseka

Zotsatira zoyipa za AC ndi lvdt zikuyenera kuwonongedwa ndi Carvo Card:

1. Kusinthana ndi kuwononga: Khadi la servo ili ndi funreta yonyamula (nthawi zambiri imakhala ndi mafunde a LVDT) kuti ikhale ndi magetsi a DC.

2. Konzani Zosagwirizana: Kulakwitsa kwa LVDt kumalipidwa ndi pulogalamu ya Algorithm kuti iwonetsetse kuti 0-00% Valve Off

3. Kufanizira-loop-loop: Deh systems ikufanizira chingwe cha LVDT ndi chizindikiro cha LVDT chomwe chikuwonetsedwa, ndipo kusiyana kumayendetsedwa ndi ntchito yotsekera kuti apange malamulo otsekeka.

Magawo wamba:

- Zosintha Zosintha Zosintha: 1kHz, Kuchedwa Kuyankha <1ms.

- Malingaliro: Mukakhala kuthwera kwathunthu kwa 100mm, kulondola kwa malo owonetsera kufika 0.01mm.

1.

SEREO VIVE G771k208 imagwiritsa ntchito chingwe chotchinga kawiri kuti upereke zizindikiro za LVDT:

- Osanjikiza wamkati wamkati amakhazikika ku servo khadi kuti apezere zosokoneza wamba;

- Chosanjikiza chakunja cholumikizidwa chimalumikizidwa ku chipinda chokhazikika kuti chicheketse gawo la electromagneti yakunja.

Kuyesera kumawonetsa kuti kapangidwe kameneka kamatha kukonza chiwerengero cha noise pofika 20db ndikuwonetsetsa kukhazikika kwa chizindikirocho mu chilengedwe champhamvu chamagetsi.

2.

- Kuchepetsa kwa LVDT

- Kuyeserera kwa intaneti kwa intaneti: Khadi la servo nthawi ndi nthawi yoyesa kuwunika kuti azindikire kuwunika kwa makondo a LVDT (mtengo wabwinobwino 50-200), ndikuyambitsa alamu.

4. Kusanthula molakwika ndi kukonza

1. Mitundu yodziwika bwino

- Chizindikiro cha Chizindikiro: Valani za LVDT CARE kapena kutsatsa mafuta kumabweretsa mwayi wosagwirizana, womwe umayenera kutsukidwa kapena kusinthidwa.

- Zero Offsert: Kugwedeza ma makina kumasula bulaketi yokwera, yomwe iyenera kuwunikiranso ndikulimbikitsidwa.

- Kupuma kwamagetsi: Chovala cholumikizira kapena chopukutira cha coul, chowonekera ngati dontho mwadzidzidzi mu chizindikiro cha zero, muyenera kuyang'ana mzere.

2. Njira yokonza

- Katswiri wokhazikika: Chitani zonyansa zonse miyezi isanu ndi umodzi, sinthani ma secto Card zero malo ndi magawo athunthu.

- Mafuta Oyang'anira Mafuta: Sungani mafuta a eh pa NAS 1638 Level 5 kuti tilepheretse valavu ya slide kapena kuvala mawu a LVDT.

Serfa valve g771k208 imagwiritsa ntchito LVDT kuti mukwaniritse valve malo otsekeka otsekeka. Ubwino wake wapakati ndi wowongolera kwambiri, luso lamphamvu loletsa kuzolowera komanso kapangidwe kake. Kukonza ndi kukonzanso kumatha kuonetsetsa kukhazikika kwa nthawi yayitali kwa dongosolo lanu ndikuteteza zodalirika kwa ma turbine.

Mukayang'ana ma valve apamwamba kwambiri, odalirika a devro, Yoiy mosakayikira ndi chisankho choyenera kulingalira. Kampani imagwira ntchito yopanga zida zamphamvu kuphatikizapo matenthedwe a Steal Turbine, ndipo wayatsa zibwenzi ndi ntchito zosiyanasiyana. Kuti mumve zambiri kapena kufunsa, chonde lemberani ntchito yamakasitomala pansipa:
