【Q&A Question 089】July 18, 2016: What are the reasons for poor cooling performance of oil coolers? The answer key will be available after responding; scoring is based on answering the key points. The temperature of the cooling water entering the system is too high, and the tube side gets blocked due to the accumulation of sediment.
Tube bundle scaling, high circulating water temperature
1. High circulating water temperature, resulting in poor cooling effect. 2. Scale buildup inside the oil cooler. 3. High ambient temperature. 4. The circulating water flow is not at full capacity!
Oil deterioration, carbonization, scale buildup, pipe blockages, and air resistance. 、
Low cooling water volume, scaling of the cooling water, excessive oil impurities that clog the cooler, high oil temperature, internal leakage in the bypass valve
The pressure and flow rate of the circulating water, as well as its water quality, are poor, which makes scaling more likely to occur
Reasons: The temperature of the cooling water entering the system is too high, and the tube side is blocked by accumulated sediment, etc.
Circulating water pressure and temperature effects, internal leakage or short circuits in the water cooler, excessive opening of the water cooler’s auxiliary lines, oil emulsification, or too many impurities, and so on
1. The pressure in the cooling water system is too low； 2. Blockage in the oil cooler water system ； 3. The oil cooler is designed with a small heat exchange area ； 4. High temperature of cooling water ； 5. The opening degree of the oil cooler water valve is too small
