Common fault repair methods for hydraulic oil radiators

hydraulic oil cooler

The upper and lower ends of the hydraulic oil radiator are two terminal boxes made of aluminum products. A part of the two terminal boxes is called a core part, which is mainly used for heat dissipation. The two terminal boxes are where the hydraulic oil and oil are exchanged for each other. The inlet and outlet of the hydraulic oil are above the previous terminal box. Do not mix water into the hydraulic oil, so that it will freeze in winter. In the process of using the machine, the fins on the radiator will accumulate a lot of dust, and it should be clear once every 100 hours to ensure that its heat dissipation performance can be fully realized. The machine is normally mounted above the flywheel housing.


When the machine fails, how should we eliminate it? Let's take a look at how to repair it. The hydraulic oil radiator does not need to be removed for inspection, and it can be checked directly in the vehicle. First check if there is any oil leakage at the joint between the radiator and each tubing. If there is oil leakage, the O-ring seal at the joint should be replaced in time. Next, there may be a radiator or tubing rupture, then the machine needs to be removed and welded before being installed. It is necessary to use a professional cleaning agent to clean the inside of the radiator, or directly blow compressed air from the oil pipe at the inlet and outlet of the radiator, clean up the old hydraulic oil remaining in the previous use, and then add a certain amount in the oil pipe. Hydraulic oil, again blown into the compressed air for cleaning.
