Wuxi Xinming avtomatik boshqaruv klapanlari sanoati sizga pnevmatik aktuatorlarning sifatini qanday baholashimiz kerakligini tanishtiradi.
Odatda, biz pnevmatik aktuatorni tanlaganimizda, biz narx va sifat haqida ko'proq tashvishlanamiz. Agar narx to'g'ri bo'lsa, biz uning sifati haqida ko'proq bilishni xohlaymiz. Agar u talablarga javob bersa, biz uni sotib olishni tanlaymiz. Axir, pnevmatik aktuator Aktuatorning sifati malakalimi yoki yo'qmi, ishlab chiqarish xavfsiz yoki yashirin xavf tug'diradimi yoki yo'qligini aniqlaydi, shuning uchun pnevmatik aktuatorning sifatini qanday baholash mumkin.
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".
Pnevmatik aktuatorlarning doimiy o'sishi bilan pnevmatik aktuatorlar juda yaxshi ko'rsatkichlarga ega. Yagona silindrli konstruksiyaga ega pnevmatik aktuator sifatida, shubhasiz, u ikki{1}}tsilindrli konstruksiya-va-raketa{2}}va{3}}tsilindrli konstruksiyaning yarmiga teng. Ikkinchidan, pnevmatik aktuator ishlayotganida, chiqish momenti burchakning o'zgarishi bilan o'zgarishi mumkin va valf ochilganda yoki yopilganda, moment qiymati katta bo'lib, bu valf qonuniga to'liq mos keladi. Rafli va pinionli aktuatorlar bilan solishtirganda, pnevmatik aktuatorlar ko'proq momentni tejashlari mumkin, chunki torkli va pinionli aktuatorlarning momenti doimiydir. Silindr korpusi ekstrudirovka qilingan alyuminiy qotishmasidan qilingan va qattiq anodizatsiya bilan ishlov beriladi. Ichki yuzasi qattiq tuzilishga ega, yuqori quvvat va qattiqlikdir. Kam ishqalanadigan materialdan yasalgan toymasin podshipniklar metallar orasidagi toʻgʻridan-toʻgʻri aloqani oldini oladi, uzoq xizmat muddati, past ishqalanish koeffitsienti va moslashuvchan aylanishga ega.
