What Should I Do If The Oil Cooler Fails?
In plastic machinery, engineering machinery, mining machinery, automotive, steel, wind power and aerospace industries, there is one important element is that they have in common, that is oil cooler, hydraulic system and lubrication system, oil cooler is as a kind of widely used oil cooling equipment plays a huge role.
There are many types of oil cooler, air cooled oil cooler is divided into tube type oil cooler, oil cooler and fin type it for plastic machinery, engineering machinery, mining machinery, automobile, steel, wind power and space industries such as relevant equipment are particularly important.
So, what impact will the oil cooler have on the equipment? In terms of hydraulic system, high oil temperature rise after long time work will release a lot of calories, if not timely take the heat out, can lead to aging, damage the sealing system, oil and oil viscosity will be as high and low temperature, oil pressure and to meet the work demand, may eventually make the whole hydraulic system paralyzed.
The main reason for this failure is that the blockage and sediment are trapped in the cooling pipe wall, which makes the heat transfer function less. In addition, the cooling water content is not sufficient, the cooling water chamber gas can also cause the cooling performance.
The solution to this problem is to start by designing structures that are difficult to block and easy to clean, as well as to increase the amount of water or cool it with cooler water. Unscrew and exhaust the screw; Cleaning the inner and outer surface of the surface.
Due to the temperature difference of the two fluids, the thermal expansion of the oil cooler material can produce thermal stress, or the inflow of oil pressure is too high. May incur damage to the parts; In addition, in cold regions or winter, when the night stops, the ice expansion in the tube will crack the cooling water pipe. Therefore, it is necessary to select the materials that are affected by the thermal expansion and adopt the deformation compensation structure such as floating head. Dry the water in the cooler every night during the cold season.
Water leakage, oil leakage occurs in the oil cooler of the end cover with the cylinder body, or because of the welding poor, the cooling water pipe rupture and other causes of oil leakage, water leakage. At this time, it can be solved by means of replacing seal and welding. When replacing seals, wash the combined face and apply a layer of adhesive.
In the cooling loop, the overflow flow of the overflow valve varies with the load flow of the system, so the heat released will also change, sometimes resulting in a waste of cooling. In order to ensure the proper oil temperature of the system, the temperature control system can be used to adjust the cooling water. If it is lower than normal oil temperature, then stop the cooler's work, or turn on the heater directly.

At this time can wash oil cooler, hose high-speed clean water rinse water cover, back cover the lining and the surface of the cooling tube, at the same time using the washing cleaning cleaning rod, finally use compressed air to blow dry. After cleaning, water pressure test can be used.
