Project Background
In automotive stamping production, the continuous operation of 2000-ton hydraulic presses generates significant heat, leading to die temperature rise. This affects forming accuracy, demolding efficiency, and die lifespan. To ensure production stability and part quality consistency, an efficient and stable cooling system was required to manage die temperature.
Chiller Equipment Configuration
A 407.9 kW water-cooled screw chiller was selected as the core refrigeration unit. Key technical advantages include:
- High energy efficiency: COP value ≥ 5.8, meeting energy-saving requirements for industrial continuous operation.
- Stable output: ±1°C water outlet temperature control precision for consistent cooling performance.
- Durability: Compressor design lifespan exceeding 100,000 hours, suitable for factory three-shift operation conditions.
- Smart control: Integrated PLC controller supports remote monitoring, fault alarms, and operation data logging.
Supporting Components
1.Cooling water circulation pumps:
- 1 fixed-frequency furnace and press circulation pump.
- 1 variable-frequency die cooling pump (energy-saving and precise temperature control).
- 1 fixed-frequency internal circulation pump.
2.Water tanks:
- 2 × 10T tanks (separate cold and hot water storage) to improve heat exchange efficiency and temperature control.
Piping System Design
- Original open cooling tower cooling circuit integrated with die cooling, press cooling, and furnace cooling backup inlet/outlet pipelines. Stainless steel globe or butterfly valves ensure manual switching of the cooling water circuit in case of chiller failure, maintaining production continuity.
- All valves (globe or butterfly) are stainless steel. Valves installed at the end of die cooling, press cooling, and furnace cooling pipelines for easy operation and maintenance, with sufficient space reserved for valve operation and repairs.
