Product features
The NUPEX combined flexible coupling is a high-performance coupling developed and marketed by Schenck Power in 2000 for the characteristics of frequency conversion units. After the successful application of Jinxi Petrochemical Plant, more than 300 units have been used so far, which are running well and have excellent results. Its structural features are as follows:
1. The latest technical support in the United States, NUP + diaphragm combination design
2. Finite element and other strength design, lighter, more convenient and safer
3. Automatic alignment, can absorb the unit in all directions misalignment, only need to be roughly installed to find the right
4. Polyurethane rubber sleeve pressure resistance, self-lubrication, permanent elasticity, three kinds of stiffness according to the torque calculation results selected
5. Built-in spherical bearings, radial support up to 5 tons, completely eliminate the middle radial support
6. The deflection stiffness of the long middle tube is adjustable, avoiding the critical speed and improving the rotor dynamic characteristics of the unit
7. Fully absorb the frequency conversion harmonic shock, shock absorption, no noise
8. 3DH phase magnetic stripe and counterweight screw hole to correct shaft unbalance
