HITORK Pneumatic control valve chinhu chakajairika chehungwaru mukuita kwekugadzira.Mune iyo control system, pneumatic control valve ichaita senge ichiita kunge kupokana.Saka chii chinokonzeresa kupokana pamavharuvhu ekudzora pneumatic?
Kukunda kupokana ndeimwe yemabasa ekutanga evhavha chinzvimbo.Iko kukweshera kwevharuvhu yekudzora kunowanzobva muzvikamu zviviri: kurongedza uye sleeve valve seal ring.Kana dzinde risina kutsvedzerera kana kurongedza kwakanyanyisa, kupokana pakati pehunde nekurongedza kunogona kuve kwakanyanya.Muzviitiko zvekushisa kwepamusoro, kupindirana kwe graphite ring uye sleeve kunowanzo shandiswa kuita kuti valve inogadzirisa isangane nedhizaini yekuisa chisimbiso zvinodiwa.Kana kukanganisa kwakakurisa kana kuti sleeve ellipse yakakurisa, kupesana pakati pe spool uye sleeve yakakura zvikuru.Nekuda kwekuti iyo static friction force yakakura kudarika kukwenya kwesimba, munhambwe yemhando yakakura yekuita, vharuvhu inosvetuka, inozivikanwawo se peristalsis.Kuchinja kwayo kuita seizvi: kana telesignal mutation (kureva nhanho chiratidzo) paitika, kutsauka kwakashata kunokonzerwa nekukwesha kwakakurisa, uye mhedzisiro yese yenzvimbo inoramba ichiwedzera kuburitsa.Kana iyo static friction simba ichiwedzera zvakakwana kukunda, valve inoita.Nekuti kukwenya kwakamira kwakakura kudarika kukweshana, valve overshoot, negative kutsauka kunova positive kutsauka.Iyo sisitimu yakaoma kudzikamisa nekuda kwekudzokororwa overshoots.Tichifunga nezvedambudziko rekukweshana, vamwe vanogadzira vanochinja vanogadzira yakakwira friction algorithm, iyo inoderedza zvakanyanya kuitika kwekushanduka kwevharuvhu.
