As we all know, the hydraulic oil in the hydraulic station of the water chiller is generally cooled by the cooling water supplied by the cooling tower. The cost of using the cooling tower is very low. However, if the heat exchanger breaks and the cooling water enters the hydraulic oil tank, a full tank of hydraulic oil will not be used. How can we improve it?
Here are two improvement methods introduced by Amy Gao's technical editor:
① For the hydraulic station equipped with heat exchanger, screw chiller with oil tank and oil pump can be used. In this way, even if the heat exchanger leaks, the quality of hydraulic oil in the oil tank will not be affected.
② For the hydraulic station without heat exchanger, the refrigerator with its own oil pump (without oil tank) can be used. The hydraulic oil in the oil pump oil tank enters the refrigerator for direct cooling. If the refrigerator leaks
The alarm will be triggered, and the quality of hydraulic oil will not be greatly affected.
③ The closed cooling tower is used for centralized water supply. The closed cooling tower is used for brief cooling to reduce the probability of leakage. However, the centralized water pipeline connection is required. The initial investment cost is high and the use is inflexible.
