L-Industrija tal-Valv ta 'Kontroll Awtomatiku ta' Wuxi Xinming se tintroduċi lilek kif għandna niġġudikaw il-kwalità ta 'attwaturi pnewmatiċi.
Normalment, meta nagħżlu attwatur pnewmatiku, aħna aktar imħassba dwar il-prezz u l-kwalità. Jekk il-prezz huwa tajjeb, irridu nkunu nafu aktar dwar il-kwalità tiegħu. Jekk tissodisfa r-rekwiżiti, aħna nagħżlu li nixtruha. Wara kollox, attwatur pnewmatiku Jekk il-kwalità tal-attwatur hijiex kwalifikata jew le tiddetermina jekk il-produzzjoni hijiex sigura u jekk hix se tikkawża perikli moħbija, allura kif tiġġudika l-kwalità tal-attwatur pnewmatiku.
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".
Biż-żieda kontinwa ta 'attwaturi pnewmatiċi, attwaturi pnewmatiċi għandhom prestazzjoni prominenti ħafna. Bħala attwatur pnewmatiku b'disinn ta'-ċilindru wieħed, huwa bla dubju nofs id-daqs tad-disinn ta'-ċilindru doppju ta' attwatur ta' rack-u-pinion. It-tieni nett, meta l-attwatur pnewmatiku jkun qed jaħdem, it-torque tal-ħruġ jista 'jinbidel bil-bidla tal-angolu, u meta l-valv jinfetaħ jew jingħalaq, il-valur tat-torque huwa kbir, li huwa eżattament konformi mal-liġi tal-valv. Meta mqabbla ma ' l-attwaturi rack u pinion, attwaturi pnewmatiċi jistgħu jiffrankaw aktar torque minħabba li t-torque ta ' l-attwaturi rack u pinion huwa kostanti. Il-korp taċ-ċilindru huwa magħmul minn liga ta 'aluminju estruż u huwa ttrattat b'anodizzar iebes. Il-wiċċ ta 'ġewwa huwa iebes fin-nisġa, għoli fis-saħħa u l-ebusija. Il-bearing li jiżżerżaq magħmul minn materjal ta 'frizzjoni baxx-jevita l-kuntatt dirett bejn il-metalli, għandu ħajja twila ta' servizz, koeffiċjent ta 'frizzjoni baxx u rotazzjoni flessibbli.
