Things to know about hydraulic oil coolers

Hydraulic oil coolers are used widely in numerous industries like, agricultural, mobile, manufacturing. Several different types of hydraulic oil coolers are suitable for hydraulic systems.

If you have decided to buy hydraulic oil cooler, here are a few things that you should keep in mind.

  • What is a hydraulic oil cooler fan?

Hydraulic air fans is primarily a device which is used to cool down or lower the temperature of the oil used in industrial hydraulic applications.

  • Use of hydraulic oil coolers

There are two ways of cooling the oil that are:

  • One of the processes is hectic and costly; it is to use enough oil so that the heat created will never become too great during a single discharge.
    • Another process is a better one which is to cool the oil so that the heat created gets dissipated. This process allows the system to operate for unlimited periods. This process also uses less oil.
  • Components of the hydraulic oil cooler
    • oil reservoir
    • cooling fan, radiator, and a mini hydraulic motor
    • relief valve
    • filter
    • oil level sight glass
    • filter block indicator
    • suction elbow and pipe gate after mounting
  • Benefits of using a hydraulic oil cooler

With the help of a hydraulic oil cooler, you can get a stable cooling and filtration process irrespective of flow and duty cycle variations of the main hydraulic circuit. One of the biggest advantages of the hydraulic oil cooler is that the cooler is completely separated from the pressures in the return line which can potentially damage the cooler. You can perform the maintenance on the filters without having to shut down the main system.

  • Requirements before buying hydraulic oil cooler
    • Amount of oil that you need to remove from the system
    • Oil temperature desired
    • Ambient air temperature and supplied water temperature
    • The flow required
    • Oil to water flow ratio
    • The viscosity of the oil
  • Maintenance tips of hydraulic oil cooler
    • Inspect the entire heat exchanger and motor assembly for loosened bolts, or loose connections, broken components, rust spots, corrosion, coil clogging, and external leakage.
    • You should keep in mind that most low horsepower electric motors do not need extra lubrication. However, if it is a larger motor it, requires a good lubrication with good quality grease as specified by the manufacturer add at least once every six to nine months.
    • It is necessary to clean and inspect the fan blades during the regular maintenance schedule. Always avoid bending or striking any of the blades while handling a fan blade. The care must be taken. The fan blades will not work properly if they get damaged.
    • Fortunately, the coil fins become flat and can be framed back into position. You may require the removal of the coil from the cabinet.
    • Heat exchangers which work in the oily and dusty environment would need to have the coil cooling fins clean. You should clean them by brushing with water or any nonaggressive degreasing agent mixture.
