Industri Injap Kawalan Automatik Wuxi Xinming akan memperkenalkan kepada anda bagaimana kami harus menilai kualiti penggerak pneumatik.
Biasanya, apabila kita memilih penggerak pneumatik, kita lebih mementingkan harga dan kualiti. Jika harganya sesuai, kami akan ingin mengetahui lebih lanjut tentang kualitinya. Jika ia memenuhi syarat, kami akan memilih untuk membelinya. Lagipun, penggerak pneumatik Sama ada kualiti penggerak itu layak atau tidak menentukan sama ada pengeluaran itu selamat dan sama ada ia akan menyebabkan bahaya tersembunyi, jadi bagaimana untuk menilai kualiti penggerak pneumatik.
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".
Dengan peningkatan berterusan penggerak pneumatik, penggerak pneumatik mempunyai prestasi yang sangat menonjol. Sebagai penggerak pneumatik dengan reka bentuk-silinder tunggal, ia sudah pasti separuh saiz reka bentuk dua-silinder bagi rak-dan-penggerak pinion. Kedua, apabila penggerak pneumatik sedang beroperasi, tork keluaran boleh berubah dengan perubahan sudut, dan apabila injap dibuka atau ditutup, nilai tork adalah besar, yang betul-betul selaras dengan undang-undang injap. Berbanding dengan penggerak rak dan pinion, penggerak pneumatik boleh menjimatkan lebih banyak tork kerana tork penggerak rak dan pinion adalah malar. Badan silinder diperbuat daripada aloi aluminium tersemperit dan dirawat dengan anodisasi keras. Permukaan dalam adalah tekstur yang keras, kekuatan dan kekerasan yang tinggi. Galas gelongsor yang diperbuat daripada bahan geseran-rendah mengelakkan sentuhan terus antara logam, mempunyai hayat perkhidmatan yang panjang, pekali geseran rendah dan putaran fleksibel.
