Transmission Application Solutions for the Chemical Industry

Industry Characteristics:

1. The drive system operates continuously at full load throughout the day. Any equipment failure can cause significant impacts such as production shutdowns, which requires gearboxes to have high reliability.
2. The continuous emergence and application of new processes and new equipment necessitate more comprehensive and advanced transmission systems.
3. Transmission systems should have higher efficiency to meet energy-saving and emission-reduction requirements.
4. With a large number of equipment, wide distribution, and difficulties in inspection, online monitoring of gearboxes and intelligent equipment management are future trends.
5. To ensure long-term stable operation of equipment, spare parts must have extremely short supply cycles.
