MuSteam Turbine Dhijitari Electro-Hydraulic Control System (Deh), Electro-hydraulicservo vharuvhuG771K208 ndiyo chikamu chepakati chekuzadzisa kudzora chaiko. Inopa vhivha vhesi mhinduro kuburikidza neLVDT kuti ive nechokwadi chekuti kurongeka uye kugadzikana kweiyo turbine vheji kugadzirisa. Chinyorwa ichi chichaongorora kuti sei servo vhairi g771k208 inogona kuwana yakakwira-chaiyo Valve chinzvimbo kubva pamaonero emhando yehunyanzvi, chiratidzo chekutapurirana, zvevhu rakavharwa, etc.

1. Chimiro uye basa rekushanda reServo Valve G771K208

Iyo servo vhezhve g771k208 inotora mota torque + maviri-stage hydraulic amplization gadziriso. Izvo zvikamu zvepakati zvinosanganisira Electromagnetic Coil, Armature, Baffle, Nozle uye Slide Valve. Kana Deh Controller anotumira nzvimbo yepasi pevhu, iyo Electromagnic Coil inogadzira munda wemagineti, anodhonzera Armature kuti atsanangure uye anotyaira bhaini kuti afambe. Shanduko iri mushe pakati peiyo baffle uye mhou pamativi ese maviri ichaumba musiyano wekumanikidza, sundidzira iyo yekufambisa yekufambisa, uye nekudaro inodzora kuyerera kwemvura inodzivirira moto mumotokari.

Key maficha:

1. Torque mota inonzwa: Iyo Armature deflection angle inoenderana neyakaenderana neyakaisa mari, uye kugadzirisa kunogona kusvika 0,1%, kunoita kuti isimbe zvakanaka-tuning kugona.

2.

2. Kuita maitiro eLVDT Valve Position mhinduro

1. Kuisa mumuviri uye chiratidzo cheLVDT

Iyo yemota yemotokari pistoni yeiyo servo vhezhve g771k208 yakabatana neyekudzora vharuvhu kuburikidza neyechina inobatanidza tsvimbo. Iyo LVDT yakarongedzwa zvakananga pamhepo dzedzimba dzekugara, uye musimboti waro waro wakabatanidzwa netsvimbo ye piston. Kana pistoni inofamba, chinzvimbo cheLVDT Iron Core shanduko, zvichikonzerwa nekushanduka kwemagineti pakati peiyo Chous

Kuisa mapoinzi:

- Iyo LVDT ZERO chinzvimbo inoda kuwiriranwa nenzvimbo yakavharwa zvakakwana yemota yekuyera, uye kutsauka kunoda kudzorwa mukati me11.1m.

- Iyo bracket stiffness inoda kusangana neVibration Frequency> 100HZ kudzivirira michina yekukanganiswa yekuvhiringidza chiratidzo.

2. Signal mamiriro uye yakavharwa-loop kutonga

Iyo AC Yakasiyanisa Signal Sign Africa neLVDT inoda kuitwa neiyo Serto Kadhi:

1. Moduline

2..

3. Yakavharwa-loop kuenzanisa kweiyo Valve Positi Command Signcal neLVDT Mhinduro chiratidzo, uye mutsauko unofambiswa neiyo pid kushanda kuti iite mutsara wakavharwa-loop.

Chaizvoizvo paramita:

- Mhinduro chiratidzo chekuvandudza frequency: 1khz, kupindura kunonoka <1ms.

- Resolution: Kana iyo izere stroke iri 100mm, iyo nzvimbo yekuona yekuona inosvika ku0.01mm.

3. Anti-kukanganiswa uye kuvimbika dhizaini

1. Electromagnetic kuenzanisa kwehurongwa

Servo Valve G771K208 inoshandisa kaviri-deloped tambo kuendesa lVDT LVDT Signs:

- Iyo yemukati mivanhi yekuchengetera yakadzika kune iyo servo kadhi yekudzvinyirira kuwanda-maitiro ekukanganisa;

- Iyo yekunze yekunyepedzera showa yakabatana nekabati pasi kuti iparadzanise iyo yekunze emagetsi emagetsignnet.

Kuedza kunoratidza kuti iyi dhizaini inogona kuvandudza chiratidzo-kune-ruzha ratio ne20db uye chengetedza kugadzikana kwechiratidzo mune yakasimba electromagnetic nharaunda yakasimba.

2. Redundancy uye kukanganisa kuongororwa

- Dual Lvdt Redundancy: Zvimwe zvikamu zvakashongedzerwa nemisangano miviri yeLvdts, uye chiratidzo chinotora kukosha kana kwakakwana kukosha, uye nekukasira kana chikanganiso chenzvimbo imwe chinoitika.

- Online Kuzvibvunza

4.

1. Zvakajairika Zvikwereti

- Signal Drift: Pfeke of the Lvdt Core kana Mafuta Andersion anotungamira kuwedzerwa isingaravirire kukanganisa, izvo zvinoda kucheneswa kana kutsiviwa.

- Zero Offset: Mechancal vibration inosunungura bracket, inoda kudzoreredzwa uye kusimbiswa.

- Kuparara kwemagetsi: Cable connector oxidation kana coil break, inoratidzwa seyakangoerekana yadonha mukupa mhinduro kune zero, inoda kutarisa mutsara kuenderera mberi.

2. Kugadzirisa zano

-Kunonoka kukaita: ita zvakakwana stroke calibration yega yega mwedzi mitanhatu, shandura servo kadhi zero zero uye zviyero zvizere paramita.

- OIL YEMAHARA Management: Chengetedza Mafuta Eh Akachena paNAS 1638 Level 5 Kuti udzivise zvidimbu kubva pakuvhara vharuvhu kana kupfeka yeLVDT Core.

Servo Valve G771K208 inoshandisa LVDT yekuzadzisa Valve Position yakavharwa-loop mhinduro. Zvakanakira izvo zvakaringana zvakakwirira-chairo chiratidzo chekushandura, yakasimba anti-yekukanganisika kugona uye redundant dhizaini. Kugadziriswa zvine musoro uye calibration inogona kuve nechokwadi chekugadzikana kwenguva refu kweiyo mhinduro yekupa mhinduro uye inopa kuchengetedzwa kwakavimbika kweiyo turbine mutemo.

Paunenge uchitsvaga yakakwirira-mhando, yakavimbika deh servo mavhavha mavhiri, yoyik pasina mubvunzo sarudzo yakakodzera kufunga nezvayo. Iyo kambani inokatyamadza mukupa mhando yemidziyo yemasimba inosanganisira steam turbine accessories, uye yakawedzera kukwikwidza kune zvigadzirwa zvemhando yepamusoro uye masevhisi.
