Notes on cooler use

(1) When the cooler is put into use, the vent valve on the cooling line should be opened to exhaust air, and closed after water is seen to prevent air blockage from affecting the cooling effect.
(2) When the cooler is shut down for line sweeping, stop the cooling water and open the cooling water vent valve at the same time to avoid pressure buildup and damage to the equipment.
(3) When adjusting the temperature of the oil after cooling, the cooling water outlet valve should be controlled first. Because the use of the inlet valve to control the water volume can save cold water, it will cause a short circuit or slow down of the water flow in the cooler, resulting in heat on the top and cold on the bottom, affecting the heat exchange effect. Therefore, it is not suitable to use inlet control.
