1. Equipment Description
Zero Dynamic’s Hard Bearing Universal Joint Drive Balance Machine for Impellers, Rollers, Shafts - YYW & HW Series (7500KG-20000KG) is suitable for the balance measurement of various workpieces like large motor rotors, wind turbines, water pumps, centrifuge impeller, rubber rollers, internal combustion engines, sieve baskets and or rotating workpieces whose outer circle is not appropriate to use belt drive or where high transmission torque is needed.
Zero Dynamic’s Hard Bearing Universal Joint Drive Balance Machine for Impellers, Rollers, Shafts - YYW & HW Series (7500KG-20000KG) adopts universal coupling drive which has advantages of smooth power transmission, fast starting, easy operation. Professionally designed support pedestals could effectively transmit mechanical force and has advantages of sturdy and reliable structure, low vibration resistance, good rigidity. The equipment uses high sensitivity piezo-electric sensors which has good linearity, durable and reliable. The equipment adopts advanced electrical measurement system with a friendly man-machine interface and full functionality. Once calibrated, permanent use, allowing very high initial unbalance.
