Parizvino, iyo valve system inonyanya kushandiswa nepneumatic actuators, magetsi actuatorsuye electro-hydraulic actuators.Zvinoenderana nehunhu hwevatatu actuators, isu tinoongorora mashandisiro avo muvharuvhu system:

Pneumatic System: Iyo pneumatic system inovimba neMhepo compressor, iyo inomanikidza mhepo, inoichenesa, inopa iyo pneumatic actuator, uye inotyaira vharafu.Iyo gasi inoburitswa yakananga kumhepo mukuita kutyaira iyo actuator, uye gasi nzira system inoda kutarisana neiyo gasi sosi nguva dzose.Nokudaro, air compressor kazhinji inoda kushandisa imwe, mugwagwa mukuru uye actuator pamberi pebazi remhepo inobata zvikamu, zvakadai seomesa, sefa decompression, mhute yemafuta, etc. Inoda nguva dzose kugadzirisa, kutsiva.Kune akawanda emhepo nzira majoini, uye kugara uchiongorora kunodiwawo kudzivirira kubuda kwemhepo uye kukanganisa system kudzvanywa.Iro basa rakaoma kudaro nderechokwadi chete kuti ive nechokwadi chekuti pneumatic actuator system inoda kuchinjira kuchiito chaicho.Iyo pneumatic actuator yehombe dhayamita vharafu, kureva, silinda, inowanzosarudzwa zvichienderana neimwe mhepo sosi kudzvanywa, asi iyo pneumatic actuator kazhinji haifambi, kana chiito hachisi panzvimbo, kana chiito chinonoka uye chiito. haina kutsvedzerera Izvi zvinowanzoitika nekuda kwezvinotevera:

Kana nzira yemhepo iine unyoro, kana tembiricha yemhepo iri pasi pe zero, mvura inotonhora, ichiomesa pneumatic actuator, kuitira kuti pneumatic actuator haigone kufamba.

Iyo gasi nzira haina kuzorwa neoiri mhute, saka actuator iri munzvimbo yakaoma kwenguva yakareba, izvo zvinoita kuti kukwesha kuwedzere zvakanyanya.Iyo actuator yakamira kana kusagona kufamba.

Iyo yekubuda kweiyo compressor yemhepo haina kukwana kana kune inodonha munzira yemhepo, izvo zvinoita kuti pneumatic actuator isawane yakakwana yekutyaira torque kuvhura vharuvhu nekukurumidza kana kuvhara vharafu zvachose.

Musiyano weiyo coefficient yekuwedzera kwekupisa kwegasi munzvimbo inotonhorera uye inopisa inotungamira kumusiyano wenguva yese yekufamba yepneumatic actuator.

Iyo gasi ine compressibility, inogona kukonzera iyo pneumatic actuator kuti imhanye mukuita kuti ive isina kutsvedzerera, iyo yakangoerekana isiriyo kufamba.

Kana chikumbiro chikakurumidza kuvharika, iyo pneumatic actuator inowanzo shongedzerwa tangi yegasi pachayo, muFast shut-off, kunyangwe gasi, simba rakadzimwa, richikwanisa kuve nechokwadi nekukasira nekudzima valve, asi nekuda kwekugumira. simba, kukurumidza kuvhara-nguva nguva haizove yakanyanya kupfupika.

Hydraulic System: Hydraulic station system uye gasi system yekushandisa yakafanana, inoda kuburitsa yakanyanya-kudzvanywa mafuta, inoda mafuta sefa, inoda kuisa mafuta.Musiyano ndiwo zvakare mukana weiyo hydraulic system, iyo hydraulic system ndeyemukati kutenderera, iyo mafuta kudzvanywa kazhinji inenge 40 ~ 120 kg, iyo hydraulic actuator idiki zvakanyanya pane pneumatic actuator, uye iyo hydraulic mafuta haina compressibility hydraulic cylinder inomhanya. zvakanaka hazvizoitike jam jitter phenomenon.Iyo hydraulic system inogona kugadzirisa zvachose kushomeka kwepneumatic system.

Kubatsira kwe hydraulic system pachayo ndeyekuita kuti vheji yakavimbika ishande yesarudzo yakanakisa, asi yakakwirira-kudzvanywa mafuta, senge kusagadziriswa kwakashata, kubuda kwemafuta kunowanzoitika.Hydraulic system components se servo valves, filters, high-pressure pipelines, zvakadai sekudhura, mari yekuchengetedza yakakwirira.

Electric actuator: electric actuator yakasiyana zvachose kubva pneumatic actuator uye hydraulic actuator, yemagetsi actuator yakasununguka zvachose kubva muhusungwa hwemhepo compressor uye hydraulic station, inongoda chete kuwana magetsi uye chiratidzo chekutyaira iyo bypass system.Kuenzaniswa nepneumatic system uye hydraulic system, iyo electric actuator inokwana, iri nyore kuisa, uye basa rekuchengetedza rakaderedzwa zvakanyanya.
