ABOUT US

Under normal circumstances, the inlet and outlet pressure difference of the oil-water cooler should be measured and checked to determine whether the tube housing is available. When there is a tube leak, it is likely to be rushed to check whether the tube is damaged, and once found, it is necessary to repair.
Due to the formation of tube leakage caused by the intense sensation of the heat exchange tube during operation, it should be necessary to stop to check and repair in time.
In the process of ordinary use, it is probably possible to regularly open the head and pipe box at both ends of the cooler, and timely clean the shell foreign matter in the tube and the stolen goods on the surface of the tube.
Check the two heads of the oil water cooler, the official box is not corrosion, rust, cracks and sand holes and other conditions, once found and timely repair.
Regularly test the pressure and leakage of the oil-water cooler control and shell, check the tightness of the bolts, and do a good job of heat preservation and anti-corrosion measures (part of the test should be carried out when necessary).
The control should also be arranged regularly to check whether the heat exchange tube is deformed and tortuous.
Check the corrosion of partitions and baffles and tie rod bolts.
Check the sealing surface of the oil water cooler to ensure that the sealing surface is free of scratches and pits.
In the normal operation of the oil-water cooler, the tube plate and pipe welding should be checked for color.
