🔹 Application of Pumps for Oil Cooler (Heat Exchanger)
1. Utilize the same pump as the Main Hydraulic Pump
- Oil from the main pump supplying the cylinders/valves is partially bypassed (return line) through the heat exchanger before returning to the tank.
- This is the most common configuration as it eliminates the need for an additional pump investment.
- Disadvantage: If the machine operates at low speeds or with intermittent loads, the oil flow may be insufficient, leading to inadequate cooling.
2. Utilize a Dedicated Cooling Pump
- A separate cooling pump is installed to continuously circulate oil through the cooler.
- This is typically a small gear pump (0.5–2 kW) that draws oil from the tank, sends it to the cooler, and returns it to the tank.
- Suitable for applications with heavy and continuous operation (e.g., CNC machines, injection molding machines, hydraulic presses) that require stable temperature control.
- Disadvantage: Involves additional costs for the pump, motor, and maintenance.
🔹 Summary
- General machinery: Utilizes the main pump for the cooling circuit.
- Machinery requiring precise temperature control or heavy-duty operation: Employs a dedicated cooling circuit pump to ensure constant oil flow.
