The following matters should be noted in the use of the oil cooler.

 

1.Check the oil cooler and the system coupling to be tight, and check all accessories and observation instruments.

2.Before using the oil cooler, to exhaust treatment, loosen the front cover (or back cover) and the screw plug on the shell, slowly pass into the water and oil, when the screw plug has water or oil overflow, respectively, and then tighten the screw plug.

3.Pass in the cold medium water first, then add the hot medium oil, otherwise it will produce thermal stress.

4.The water should be added slowly, do not put in a large amount of cooling water, so as not to form a "super-cooled layer" in the tube and reduce the heat transfer effect.

5.Adjust the cooling water intake to maintain the required temperature of the oil.

6.The oil side pressure must be greater than the water side pressure.

The temperature condition adjustment of the cooler (or switching heat exchanger) is based on the central temperature. The "middle" mentioned here does not refer to the central position of geometric dimension, but refers to the temperature on the barrel (or switching channel) near the central air extraction or the outlet of circulation. It is also related to the location where the thermometer is installed. The purpose of temperature condition adjustment is to keep the temperature difference between cold end and hot end within the specified range. Then, why should the temperature in the middle prevail? We need to take a look at the relationship between the temperature of the middle part and the temperature difference of the cold end and the temperature difference of the hot end, and what rules the temperature changes along the height direction of the cooler (or the switching heat exchanger) follow. The temperature condition change of the cooler (or switching heat exchanger) is general...
