Iyo pneumatic actuator's primary accessory ndeyekudzora vharafupositioner.Inoshanda pamwe chete neiyo pneumatic actuator kuwedzera iyokurongeka kwevharuvhu, kuderedza migumisiro yesimba risina kuenzana uye kuputika kwedzinde, uye iva nechokwadi chokuti valve inopindura chiratidzo chemutongi.kuwana nzvimbo yakakodzera.

Mamiriro ezvinhu anotevera anoda kushandiswa kwelocator:
Kana iyo yepakati kudzvanywa kwakakwira uye kune yakakosha kudzvanywa musiyano;2. Kana iyo caliber yevharuvhu yekudzora yakakura (DN> 100);
3. Ivhavha inogadzirisa kupisa kwepamusoro kana kuderera;
4. Kana zvakakosha kukurumidza kuita basa revharuvhu yekudzora;
5. Kana zviratidzo zvakajairika zvichishandiswa kutyaira actuators neasina kujairika matsutso mazinga (spring siyana kunze kwe20-100KPa);
6. Pese panoshandiswa kupatsanura-renji kudzora;
7. Kana vharuvhu ichitenderedzwa, mhepo-ku-kuvhara uye mhepo-ku-ku-yakavhurika nzira inochinjana;
8. Kana iyo positioner cam inoda kuchinjwa kuitira kuti ichinje maitiro ekuyerera kwevhavha;
9. Kana chiito chakaenzana chichizoitwa, hapana piston actuator kana spring execution mechanism;
10. Magetsi-pneumatic valve positioners inofanira kugoverwa pakushandisa zviratidzo zvemagetsi kudzora pneumatic actuators.

Iyo electromagnetic valve: A valve solenoid inofanira kuiswa muhurongwa apo chirongwa chekutonga kana maviri-chinzvimbo chekutonga chinodiwa.Kudyidzana pakati pevharuvhu ye solenoid uye vheji inogadzirisa inofanira kuverengerwa pakusarudza solenoid valve kuwedzera kune AC uye DC simba sosi, voltage, uye frequency.Inogona kuve ne "kazhinji yakavhurika" kana "kazhinji yakavharwa" mashandiro.
Mavhavha maviri e-solenoid anogona kushandiswa pamwe chete kana zvakakosha kuwedzera simba revhavha kuitira kuti kuderedza nguva yekuita, kana solenoid valve inogona kushandiswa sevhavha yekufambisa pamwe chete nehombe-capacity pneumatic relay.

Pneumatic relay: A pneumatic relay imhando yemagetsi amplifier inogona kuendesa chiratidzo chemhepo yemhepo kunzvimbo iri kure kuti ibvise lag inounzwa nekurebesa kwepombi.Pakati pemutongi nevhavha yekudzora munda, kune rimwe basa rekuwedzera kana kurerutsa chiratidzo.Iyo inonyanya kushandiswa pakati peiyo munda transmitter uye yekudzora mudziyo mukamuri yepakati yekudzora.

converter:
Iyo inoshandura yakakamurwa kuita gasi-magetsi inoshandura uye yemagetsi-gasi inoshandura.Basa rayo nderekuona kutendeuka kweumwe hukama pakati pegesi nemagetsi masaini.Inonyanya kushandiswa kushandura 0 ~ 10mA kana 4 ~ 20mA yemagetsi chiratidzo chekushandura kana 0 ~ 100KPa gasi chiratidzo mu 0 ~ 10mA kana 4 ~ 20mA chiratidzo chemagetsi.

regulator yemafirita emhepo:

Chishandiso chinosungirirwa chinoshandiswa neindasitiri otomatiki michina ndiyo air filter pressure yekudzikisa vharafu.Basa rayo rekutanga ndere kudzikamisa kudzvanywa padanho raunoda uchisefa nekuchenesa mweya wakamanikidzwa unobva kumhepo compressor.Mhepo silinda, midziyo yekupfapfaidza, zvitubu zvemhepo, uye kudzvanya zvigadziriso zvezvishandiso zvidiki zvepneumatic mimwe mienzaniso yezviridzwa zvepneumatic uye solenoid mavharuvhu ayo anogona kushandiswa mukati.

Chengetedzo vharafu (self-locking valve)

The self-locking valve inzira inochengetedza valve panzvimbo.Kana sosi yemhepo ikatadza, mudziyo unogona kudzima chiratidzo chemhepo kuti uchengetedze membrane chamber kana cylinder's pressure sign pa pre-faluble level uye nzvimbo yevharuvhu pakurongeka kwayo kusati kwatadza.Kumugumisiro wekuchengetedzwa kwechigaro.

chinzvimbo transmitter yemavharuvhu
Kana iyo vheji yekudzora iri kure nekamuri yekudzora, zvinodikanwa kushongedza iyo valve chinzvimbo chinotapurirana, icho chinoshandura kutamiswa kwevhavha kuvhurika kuita chiratidzo chemagetsi uye kuchitumira kukamuri yekudzora zvinoenderana neyakatemerwa mutemo, kuti kunyatsonzwisisa kushandura chinzvimbo chevhavha pasina kuenda kunzvimbo.Chiratidzo chinogona kunge chiri chiratidzo chinoramba chichimirira chero kuvhurika kwevharuvhu kana kuti inogona kutorwa sebasa rekudzosera kumashure kwevharuvhu.

Kukurukurirana chinja paunenge uchifamba
Iyo yekumisikidza switch inhengo iyo panguva imwe chete inotumira chiratidzo chechiratidzo uye inoratidza nzvimbo mbiri dzakanyanyisa dzevharuvhu.Imba yekudzora inogona kuzivisa mamiriro ekuchinja kwevhavha zvichienderana nechiratidzo ichi uye kutora danho rakakodzera.
