Bydd Diwydiant Falf Rheoli Awtomatig Wuxi Xinming yn cyflwyno i chi sut y dylem farnu ansawdd actiwadyddion niwmatig.
Fel arfer, pan fyddwn yn dewis actuator niwmatig, rydym yn poeni mwy am bris ac ansawdd. Os yw'r pris yn iawn, byddwn am wybod mwy am ei ansawdd. Os yw'n bodloni'r gofynion, byddwn yn dewis ei brynu. Wedi'r cyfan, mae actuator niwmatig P'un a yw ansawdd yr actuator yn gymwys ai peidio yn pennu a yw'r cynhyrchiad yn ddiogel ac a fydd yn achosi peryglon cudd, felly sut i farnu ansawdd yr actuator niwmatig.
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".
Gyda chynnydd parhaus actiwadyddion niwmatig, mae gan actiwadyddion niwmatig berfformiad amlwg iawn. Fel actiwadydd niwmatig gyda-dyluniad silindr sengl, mae'n ddiamau hanner maint y -dyluniad silindr dwbl ar gyfer actiwadydd rac-a-pinion. Yn ail, pan fydd yr actuator niwmatig ar waith, gall y torque allbwn newid gyda newid yr ongl, a phan fydd y falf yn cael ei hagor neu ei chau, mae'r gwerth torque yn fawr, sy'n union yn unol â chyfraith y falf. O'i gymharu â actuators rac a phiniwn, gall actuators niwmatig arbed mwy o trorym oherwydd bod torque actuators rac a phiniwn yn gyson. Mae'r corff silindr wedi'i wneud o aloi alwminiwm allwthiol ac yn cael ei drin ag anodizing caled. Mae'r arwyneb mewnol yn galed mewn gwead, yn uchel mewn cryfder a chaledwch. Mae'r dwyn llithro wedi'i wneud o ddeunydd ffrithiant isel yn osgoi'r cyswllt uniongyrchol rhwng metelau, mae ganddo fywyd gwasanaeth hir, cyfernod ffrithiant isel a chylchdroi hyblyg.
