Wuxi Xinming Automatic Control Valve Industry predstavit će vam kako bismo trebali ocjenjivati kvalitetu pneumatskih aktuatora.
Obično, kada biramo pneumatski aktuator, više smo zabrinuti za cijenu i kvalitetu. Ako je cijena ispravna, željet ćemo znati više o njegovoj kvaliteti. Ako udovoljava zahtjevima, odlučit ćemo ga kupiti. Uostalom, pneumatski aktuator Od toga je li kvaliteta aktuatora kvalificirana ili ne određuje je li proizvodnja sigurna i hoće li prouzročiti skrivene opasnosti, pa kako procijeniti kvalitetu pneumatskog aktuatora.
The first, and most important, is tightness. The sealing performance of a pneumatic actuator directly determines whether it will leak. The current pneumatic actuator seals are mainly hard seals and soft seals. have their own suitable medium. The second is action sensitivity and reliability, which refers to the sensitivity of the pneumatic actuator to respond to changes in medium parameters. For throttle valves, pressure reducing valves, regulating valves and other actuators used to adjust medium parameters, as well as safety valves, pigging valves and other pneumatic actuators with specific functions, their functional sensitivity and reliability are very important technical performances index.
The third is the opening and closing speed of the switch. The opening and closing speed is expressed by the time required for the actuator to complete an opening or closing action. Generally, there are no strict requirements on the opening and closing speed of pneumatic actuators, but some working conditions have special requirements on the opening and closing speed. Some require rapid opening or closing to prevent accidents, and some require slow closing to prevent water hammer. etc., which should be taken into account when choosing the actuator type. The fourth is the problem of medium circulation. The suitability of medium recirculation will affect the product pressure. Therefore, when designing a pneumatic actuator, it is necessary to reduce its resistance to the medium as much as possible. Pneumatic actuators are produced according to the high requirements of working conditions. In the future, it will be an era of major leadership. The appearance and structure of the pneumatic actuator not only meets the requirements of explosion-proof, but also small in size, light in weight and large in torque, because it adopts the transmission structure design of "single-cylinder double-piston-variable torque".
Uz kontinuirano povećanje pneumatskih aktuatora, pneumatski aktuatori imaju vrlo istaknute performanse. Kao pneumatski aktuator s jednom-izvedbom cilindra, nedvojbeno je upola manji od dizajna dvostrukog-konstrukcije zupčanika-i-zupčanika. Drugo, kada je pneumatski aktuator u radu, izlazni moment se može mijenjati s promjenom kuta, a kada je ventil otvoren ili zatvoren, vrijednost momenta je velika, što je točno u skladu sa zakonom ventila. U usporedbi s aktuatorima zupčanika i zupčanika, pneumatski aktuatori mogu uštedjeti više zakretnog momenta jer je zakretni moment aktuatora zupčanika i zupčanika konstantan. Tijelo cilindra izrađeno je od ekstrudirane aluminijske legure i obrađeno je tvrdom anodiziranjem. Unutarnja površina je tvrda teksture, visoke čvrstoće i tvrdoće. Klizni ležaj izrađen od materijala niskog{4}}trenja izbjegava izravan kontakt između metala, ima dug vijek trajanja, nizak koeficijent trenja i fleksibilnu rotaciju.
