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<h2 data-start=\"729\" data-end=\"767\">\u0938\u0902\u0930\u091a\u0928\u093e\u0924\u094d\u092e\u0915 \u0930\u091a\u0928\u093e \u0906\u0923\u093f

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\u20138,000 rpm frequency range. This ultra-low reading is a stand-test result obtained under controlled conditions, not a typical field-measurement figure.<\/p>\n<h3 data-start=\"2549\" data-end=\"2598\">\u091f\u092a\u094d\u092a\u093e 2 \u2013 High-Speed Flexible Rotor Balancing<\/h3>\n<p data-start=\"2600\" data-end=\"3067\">\u0926\u0941\u0938\u0931\u094d\u092f\u093e \u091f\u092a\u094d\u092a\u094d\u092f\u093e\u0924 balancing rotor \u091a\u094d\u092f\u093e operational speed \u0935\u0930 \u0915\u0947\u0932\u0947 \u091c\u093e\u0924\u0947 \u2014 pump model \u0928\u0941\u0938\u093e\u0930 42,000 \u0915\u093f\u0902\u0935\u093e 60,000 rpm. \u092f\u093e \u0935\u0947\u0917\u093e\u0935\u0930 rotor flexible \u0938\u094d\u0925\u093f\u0924\u0940\u0924 \u092a\u094d\u0930\u0935\u0947\u0936 \u0915\u0930\u0924\u094b \u0906\u0923\u093f \u0935\u093f\u0915\u0943\u0924 \u0939\u094b\u0924\u094b, \u091c\u094d\u092f\u093e\u092e\u0941\u0933\u0947 \u0905\u0924\u093f\u0930\u093f\u0915\u094d\u0924 dynamic imbalance \u0928\u093f\u0930\u094d\u092e\u093e\u0923 \u0939\u094b\u0924\u094b. \u0939\u0947 \u092a\u0930\u093f\u0923\u093e\u092e \u0915\u092e\u0940 \u0915\u0930\u0923\u094d\u092f\u093e\u0938\u093e\u0920\u0940 \u0905\u0902\u0924\u093f\u092e correction \u091a\u0940 \u0917\u0923\u0928\u093e \u0915\u0930\u0942\u0928 \u0924\u0940 \u0932\u093e\u0917\u0942 \u0915\u0947\u0932\u0940 \u091c\u093e\u0924\u0947. high-speed balancing \u0928\u0902\u0924\u0930 residual vibration \u092a\u093e\u0924\u0933\u0940 0.3 mm\/s RMS \u092a\u0947\u0915\u094d\u0937\u093e \u091c\u093e\u0938\u094d\u0924 \u0930\u093e\u0939\u0924 \u0928\u093e\u0939\u0940, \u091c\u094d\u092f\u093e\u092e\u0941\u0933\u0947 pump \u091a\u0947 \u0926\u0940\u0930\u094d\u0918\u0915\u093e\u0932\u0940\u0928 \u0938\u094d\u0925\u093f\u0930 \u0915\u093e\u0930\u094d\u092f \u0938\u0941\u0928\u093f\u0936\u094d\u091a\u093f\u0924 \u0939\u094b\u0924\u0947.<\/p>\n<h2 data-start=\"3069\" data-end=\"3099\">\u0915\u093e\u0930\u094d\u092f\u092a\u094d\u0930\u0926\u0930\u094d\u0936\u0928 \u0935\u0948\u0936\u093f\u0937\u094d\u091f\u094d\u092f\u0947<\/h2>\n<ul data-start=\"3101\" data-end=\"3309\">\n<li data-start=\"3101\" data-end=\"3170\">\n<p data-start=\"3103\" data-end=\"3170\"><strong data-start=\"3103\" data-end=\"3140\">Residual vibration (\u0915\u0920\u094b\u0930 \u091f\u092a\u094d\u092a\u093e):<\/strong> \u2264 0.01 mm\/s (3,500\u20138,000 rpm, stand-test result)<\/p>\n<\/li>\n<li data-start=\"3171\" data-end=\"3244\">\n<p data-start=\"3173\" data-end=\"3244\"><strong data-start=\"3173\" data-end=\"3213\">Residual vibration (flexible \u091f\u092a\u094d\u092a\u093e):<\/strong> \u2264 0.3 mm\/s (42,000\u201360,000 rpm)<\/p>\n<\/li>\n<li data-start=\"3245\" data-end=\"3309\">\n<p data-start=\"3247\" data-end=\"3309\"><strong data-start=\"3247\" data-end=\"3282\">Balancing \u0938\u093e\u0920\u0940 \u090f\u0915\u0942\u0923 cycle time:<\/strong> \u0938\u093e\u0927\u093e\u0930\u0923\u092a\u0923\u0947 30 \u092e\u093f\u0928\u093f\u091f\u093e\u0902\u092a\u0947\u0915\u094d\u0937\u093e \u0915\u092e\u0940<\/p>\n<\/li>\n<\/ul>\n<h2 data-start=\"3311\" data-end=\"3324\">\u0928\u093f\u0937\u094d\u0915\u0930\u094d\u0937<\/h2>\n<p data-start=\"3326\" data-end=\"3720\">Vacuum pump rotors \u0938\u093e\u0920\u0940\u091a\u093e \u0939\u093e high-speed balancing stand \u0938\u0902\u0930\u091a\u0928\u093e\u0924\u094d\u092e\u0915 stiffness, \u0905\u091a\u0942\u0915 \u092e\u093e\u092a\u0928 \u0906\u0923\u093f \u092a\u094d\u0930\u0917\u0924 \u0938\u0902\u0917\u0923\u0928 \u092f\u093e\u0902\u091a\u093e \u0938\u0902\u0917\u092e \u0906\u0939\u0947. \u0924\u094b \u092a\u094d\u0930\u0924\u094d\u092f\u0915\u094d\u0937 \u0915\u093e\u0930\u094d\u092f\u0938\u094d\u0925\u093f\u0924\u0940\u0902\u092e\u0927\u094d\u092f\u0947 \u0905\u091a\u0942\u0915 balancing \u0936\u0915\u094d\u092f \u0915\u0930\u0924\u094b \u0906\u0923\u093f static \u0924\u0938\u0947\u091a dynamic imbalances \u0926\u094b\u0928\u094d\u0939\u0940\u091a\u0940 \u092d\u0930\u092a\u093e\u0908 \u0915\u0930\u0924\u094b. \u0939\u0947 \u0938\u092e\u093e\u0927\u093e\u0928 \u0915\u0920\u094b\u0930 vibration standards \u092a\u0942\u0930\u094d\u0923 \u0915\u0930\u0924\u0947 \u0906\u0923\u093f high-speed vacuum pump systems \u091a\u0940 reliability \u0906\u0923\u093f service life \u0932\u0915\u094d\u0937\u0923\u0940\u092f\u0930\u0940\u0924\u094d\u092f\u093e \u0938\u0941\u0927\u093e\u0930\u0924\u0947.<\/p>\n<\/div>\n<\/div><\/div><\/div><\/div><\/div>","protected":false},"excerpt":{"rendered":"<p>High-Speed Rotor Balancing Stand for Vacuum Pumps Introduction Balancing of high-speed rotors in vacuum pumps requires specialized equipment capable of maintaining accuracy under extreme operational conditions.
