What Is A Hydraulic Oil Cooler?

During the working process of the hydraulic press, most of the energy loss is converted into heat energy, which causes the temperature of the hydraulic oil to rise. If the oil temperature is too high, the viscosity of the hydraulic oil, the volumetric efficiency, and the working efficiency of the hydraulic system will be reduced, and even the hydraulic press will not work normally; the aging of the rubber seal will be accelerated, the service life will be shortened, and even the sealing will be lost, causing the hydraulic press system to leak seriously. Therefore, hydraulic presses often need to be equipped with industrial hydraulic oil coolers.

What Is A Hydraulic Oil Cooler?

There are many types of industrial hydraulic oil coolers, including industrial air coolers, industrial water coolers, oil/water air coolers, industrial oil coolers, tube coolers, plate coolers, etc. The cooling capacity of the hydraulic oil cooler is expressed in a variety of unit systems, such as W/℃, Kcal/h, W, cal/s, m2, etc.

The normal working temperature of the hydraulic oil of the hydraulic press is generally 15℃~55℃. If it exceeds 55℃, it will automatically alarm to remind the user to turn on the cooler of the hydraulic press. If it exceeds 60℃ and lasts for more than 5 minutes, it will automatically stop.

Small and medium-sized hydraulic presses mostly use plate oil coolers, which are more cost-effective. Small hydraulic presses or hydraulic systems with low system power use air oil coolers or tube oil coolers. Large hydraulic presses have high power consumption, fast working speed, long pressurization stroke, and high system calorific value. They are generally equipped with industrial oil coolers, which have a good cooling effect but high costs.
