Pendirian Pengimbangan Rotor Berkelajuan Tinggi untuk Pam Vakum<\/h1>\n

Pendahuluan<\/h2>\n

Balancing of high-speed rotors in vacuum pumps requires specialized equipment capable of maintaining accuracy under extreme operational conditions. To meet these requirements, dedicated balancing stands were developed in 2002 and 2009. These systems are designed for dynamic balancing of assembled turbine rotors at actual operational speeds ranging from 42,000 to 60,000 rpm, directly in their own bearing supports. The design objective was to achieve residual imbalance values in accordance with Class 1 accuracy as per GOST 22061-76, the Soviet balance quality standard (its modern international counterpart is ISO 21940-11, formerly ISO 1940-1).<\/p>\n

Reka Bentuk dan Konfigurasi Struktur<\/h2>\n

Rajah 1 menunjukkan susun atur skema pendirian pengimbangan berkelajuan tinggi yang digunakan untuk pemutar pam vakum.<\/p>\n

Rajah 1 \u2013 Susun atur struktur dirian pengimbang pam vakum berkelajuan tinggi:<\/strong>
1 \u2013 Platform tegar
2 \u2013 Mata air pengasing getaran silinder
3 \u2013 Tapak pelekap berbentuk silinder
4 \u2013 Pam vakum seimbang
5 \u2013 Penutup pelindung
6 \u2013 Penderia sudut fasa
7 \u2013 Sensor getaran pada penutup
8 \u2013 Sensor getaran pada tapak
9 \u2013 Unit pengukur dan pengiraan<\/p>\n

Pendirian dibina pada platform segi empat tepat (1), disokong oleh empat mata air silinder (2), yang menyediakan pengasingan getaran. Platform ini diperkukuh dengan pengaku membujur dan melintang, mencapai kekukuhan tinggi sambil meminimumkan berat. Penyelesaian struktur ini memastikan kepekaan yang tinggi terhadap daya ketidakseimbangan dan menghalang ayunan resonans di seluruh julat kelajuan pam semasa pengimbangan.<\/p>\n

Tapak pelekap (3) dipasang dengan tegar pada platform dan berfungsi untuk meletakkan pam (4) dengan tepat. Pam disertakan dengan penutup khusus (5), yang juga menempatkan sensor sudut fasa (6). Dua penderia getaran (7 dan 8) dipasang pada penutup dan tapak, masing-masing. Semua penderia disambungkan kepada unit pengukur dan pengkomputeran (9), yang menjalankan analisis masa nyata dan mengira pemberat pembetulan.<\/p>\n

Prosedur Pengimbangan<\/h2>\n

Pengimbangan dijalankan dalam dua peringkat berurutan untuk memastikan ketepatan di bawah kedua-dua keadaan rotor tegar dan fleksibel.<\/p>\n

Peringkat 1 \u2013 Pengimbangan Rotor Tegar<\/h3>\n

In the initial stage, the pump rotor is balanced at rotational speeds up to 8,000 rpm, where it behaves as a rigid body. The objective here is to compensate for both static and couple imbalances. In tests on this vibration-isolated stand, the system achieves residual vibration levels below 0.01 mm\/s RMS in the 3,500\u0432\u0402\u201c8,000 rpm frequency range. This ultra-low reading is a stand-test result obtained under controlled conditions, not a typical field-measurement figure.<\/p>\n

Peringkat 2 \u2013 Pengimbangan Rotor Fleksibel Berkelajuan Tinggi<\/h3>\n

Pada peringkat kedua, pengimbangan dilakukan pada kelajuan operasi rotor\u2014sama ada 42,000 atau 60,000 rpm, bergantung pada model pam. Pada kelajuan ini, pemutar memasuki keadaan fleksibel dan mengalami ubah bentuk, yang membawa kepada ketidakseimbangan dinamik tambahan. Pembetulan akhir dikira dan digunakan untuk meminimumkan kesan ini. Tahap getaran sisa selepas pengimbangan kelajuan tinggi tidak melebihi 0.3 mm\/s RMS, memastikan operasi stabil jangka panjang pam.<\/p>\n

Ciri-ciri Prestasi<\/h2>\n
    \n
  • \n

    Getaran sisa (peringkat tegar):<\/strong> \u0432\u2030\u00a4 0.01 mm\/s (3,500\u0432\u0402\u201c8,000 rpm, stand-test result)<\/p>\n<\/li>\n

  • \n

    Getaran sisa (peringkat fleksibel):<\/strong> \u2264 0.3 mm\/s (42,000\u201360,000 rpm)<\/p>\n<\/li>\n

  • \n

    Jumlah masa kitaran untuk mengimbangi:<\/strong> Biasanya di bawah 30 minit<\/p>\n<\/li>\n<\/ul>\n

    Kesimpulan<\/h2>\n

    Pendirian pengimbangan berkelajuan tinggi untuk pemutar pam vakum menggabungkan ketegaran struktur, pengukuran ketepatan dan pengiraan lanjutan. Ia membolehkan pengimbangan yang tepat di bawah keadaan operasi sebenar, mengimbangi ketidakseimbangan statik dan dinamik. Penyelesaian ini memenuhi piawaian getaran yang ketat dan meningkatkan kebolehpercayaan dan hayat perkhidmatan sistem pam vakum berkelajuan tinggi dengan ketara.<\/p>\n<\/div>\n<\/div><\/div><\/div><\/div><\/div>","protected":false},"excerpt":{"rendered":"
