Q: What’s the difference between the returning cooling and the separating cooling?
A: The returning cooling is only often used inChinaandTaiwan, Separating cooling is usually in Europe and American where the air cooler is more popular than water cooler.
The reason why this situation occurs is the hydraulic manufacturer were the water cooler user before and bring the air cooler to their system directly without any consideration about the difference of 2 kind of coolers. This may cause troubles and failure of cooling.
The shortcoming of Returning Cooling is:
1. By pass. The cooler will be destroyed if without by pass or wrong by pass assembly.
2. When mount a correct by pass, the spring will be broken probably because the spring compressed whenever the check valve runs through the oil returning. This leads a bad cooling efficiency.
3. The heat oil to the cooler is not steady and constant and it also causes a bad cooling.
4. In case of the cooler failure (destroyed or leakage), The machine have to be stopped to fit The production line is broken.
There is no shortcoming above in Separating Cooling, The oil is steady and constant as well the performance of cooler is on a top grade. The system works always even though the failure comes since it runs in a separated cycle.
Q: I have to decide to use the air cooler, How can I assembly?
A: The separating Cooling is strong commanded because of its best cooling capacity, The by pass is necessary if you use Returning Cooling which causes cooler broken easily as long as a wrong by pass configuration.
Separating Cooling is popular in Europe and American. The way to it is just a small pump which pumps the hot oil to the cooler and return back to the tank after cooling. It is separated from the working cycle, more safety and efficiency. A cutting cooling water pump is available for the separated pump sometimes. Please confirm with your customer and make sure of a correct by pass assembly if you insist on Returning Cooling
