Help: Problem with poor cooling performance of the oil cooler
Thread Content
Dear experts, the oil cooler of the device is located at the farthest point from the outlet of the circulation water pump; a decrease in the amount of circulation water leads to excessively high oil temperature at the outlet. Are there any solutions? I’d like to ask the experts
Lower the temperature of the circulating water, or reduce the opening of the oil inlet valve
Hello, you can try the following methods to improve the cooling efficiency of the oil cooler: 1. Increase the flow rate of the circulation water pump to ensure that sufficient cooling water reaches the oil cooler. 2. Inspect and clear blockages in the water and oil circuits to improve heat exchange efficiency. 3. If possible, consider reconfiguring the piping so that the oil cooler is located closer to the water pump outlet. 4. Check for air entering the system, which can reduce cooling efficiency, and remove it promptly. 5. Consider adding an auxiliary cooling cycle or using a more efficient oil cooler. .
Typical water circulation systems control the total return flow to maintain the system pressure, while each cooling device is designed to regulate the flow rate of the cooling water. Each cooling device needs to be adjusted to optimal conditions; only when the control parameters meet the proper cooling requirements can the operating conditions of all devices in the system be ensured. It is recommended to check that cooling water is not used in excess at each cooling point. Also, each cooler should use a return water valve to control the amount of cooling water. The cooling points should be allocated reasonably so that all can meet the design requirements. For reference.
Since it is known that insufficient flow requires adjustments, the water temperature can be adjusted if conditions permit.
What’s wrong with the farthest end? Is the pressure difference between the supply water and return water low? It is recommended to reduce the amount of circulating water used in other areas, or to install a separate circulating water booster pump for this heat exchanger.
It’s been explained very well above; I’d like to add one more thing: check whether there is any scaling on the oil cooler Install physical scale prevention equipment to prevent scaling and improve the heat exchange efficiency of the oil cooler.
