Diesel Generator Set Intercooler Function and Cleaning Method

Do you know what is the intercooler of diesel generator set? As an important part of the supercharged engine, most of the intercooler are installed in front of the radiator of the water tank. Their appearance and structure also have a lot in common with the water tank. In supercharged diesel generator sets, the water-cooled intercooler is generally used, which is composed of a shell and an inner core. Next, Dingbo Power will introduce the function and cleaning method of the intercooler of the diesel generator in detail.

The diesel generator intercooler is used to cool the supercharged air and reduce the inlet air temperature after supercharging. The temperature drop of charge air in intercooler of diesel generator is generally 25~60 ℃. On the one hand, it can increase the inflation density, and on the other hand, it can also reduce the cylinder temperature at the end of the intake and the average temperature of the entire cycle. The supercharged diesel generator for power generation generally adopts water-cooled intercooler.

After the turbocharger and intercooler are assembled, the lubricating oil circuit and coolant circuit of the diesel generator are also changed according to the detailed conditions to meet the needs of turbocharging and intercooling.

The internal pipes of the intercooler are often attached with oil sludge, gum and other dirt, which not only narrows the air flow channel, but also weakens the cooling heat exchange capacity, so maintenance and cleaning must be carried out. Generally, the interior of the intercooler shall be cleaned and tested every year or when the diesel generator is overhauled and the water tank is welded.

When the diesel generator is rapidly loaded to high speed, some black smoke is discharged from the exhaust pipe. When there is a slight air leakage sound during idle speed operation, attention should be paid to check and repair the source of the air leakage. It is the intercooler inlet hose (supercharger intercooler) that cracked, leading to air leakage. Especially during high-speed operation, a large amount of high-pressure gas from the supercharger leaked from the hose crack, reducing the amount of air entering the cylinder from the chamber, Affects the power output of diesel generator. Causing poor loading at medium to high speeds.

Cleaning plan: Add an aqueous solution containing 2% soda ash (the temperature should be 70-80 ℃) into the intercooler, fill it up, wait for 15 minutes, and check whether there is water seepage in the intercooler. If any, it should be disassembled, inspected, and welded for repair (the same as repairing the water tank); If there is no water seepage, shake it back and forth several times, pour out the washing solution, then fill it with a clean water solution containing 2% pure alkali for flushing until it is relatively clean, and then add clean hot water (80-90 ℃) for cleaning until the discharged water is clean.
