Iyo pneumatic actuator'syekutanga chishongedzo ndiyo inogadzirisa vharafu chinzvimbo. Inoshanda pamwe chete nepneumatic actuator kuti iwedzere kurongeka kwevharuvhu, kudzikamisa mhedzisiro yesimba repakati kusaenzana uye kukweshera kwedzinde, uye ita shuwa kuti vharafu inopindura chiratidzo chemutongi. kuwana nzvimbo yakakodzera.

Mamiriro ezvinhu anotevera anoda kushandiswa kwelocator:

1. Kana paine mutsauko wakakosha wekumanikidza uye kudzvanywa kwepakati;

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 chakaenzanirana chichidiwa, hapana chikonzero chechitubu kana piston actuator;

10. Magetsi-pneumatic valve positioners inofanira kugoverwa pakushandisa zviratidzo zvemagetsi kudzora pneumatic actuators.

Iyo electromagnetic valve:
A solenoid valve 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 revhavhavha kuitira kuderedza nguva yekuita, kana solenoid valve inogona kushandiswa sevhavha yekufambisa pamwe chete nehombe-capacity pneumatic relay.
Pneumatic relay:
A pneumatic relay imhando yesimba amplifier inogona kufambisa chiratidzo chemhepo kure kure kuderedza lag nguva inounzwa nechiratidzo pombi inotambanudza. 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:
Kune marudzi maviri evashanduri: magetsi-gasi anoshandura uye gasi-magetsi anoshandura. Kuona kudzokororwa kwechinjo chehukama pakati pegesi nemagetsi masaini ndizvo zvazvinoita. Inonyanya kushandiswa kushandura 0 100KPa gasi zviratidzo mu 0 10 mA kana 0 4 mA masaini emagetsi, kana 0 10 mA kana 4 mA masaini emagetsi mu 0 10 mA kana 4 mA zviratidzo zvemagetsi.

Air filter regulator:
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 kudzikamisa zvigadziriso zvezvishandiso zvidiki zvepneumatic mimwe mienzaniso yezviridzwa zvepneumatic uye solenoid mavharuvhu ayo anogona kushandiswa mukati.

Kuzvivharira vharuvhu (vharuvhu yekuchengetedza):
The self-locking valve inzira inoita kuti valve irambe iripo. 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.

vharafu chinzvimbo transmitter
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 chinja chinzvimbo chevhavha pasina kuenda kunzvimbo. Chiratidzo chinogona kunge chiri chiratidzo chinoramba chichimirira chero kuvhurika kwevharuvhu kana kuti inogona kutorwa sebasa rekudzosera kumashure kwevharuvhu.

Kuchinja kwekufamba (mutauriri)
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.
