How to prevent bubbling in the oil tank of the diesel generator set is because the high-pressure gas in the oil cylinder intrudes into the cooling waterway. The causes and methods of gas channeling are as follows.
1. The head nut is not fastened according to the specified torque. If the torque is too small, the cylinder head cannot be pressed, and the high-pressure gas will escape into the waterway. Tighten top nut at specified torque and retighten regularly.
2. If the cylinder washer is used for too long, it will be washed away or burned out, and the sealing will become worse, resulting in air leakage. Replace the cylinder washer with a new one.
3. The surface processing of the outer cover is uneven or deformed, resulting in air leakage. Grind the cover flat or replace the cover.
4. Due to improper assembly, the shoulder of the cylinder bore was broken and the air leaked. Replace the cylinder bore in accordance with the prescribed method.
5. The shoulder height of the cylinder bore is not enough, or the depth of the body into the shoulder hole is too large. After the cylinder bore enters the body, the protruding plane height of the body is not enough, and the body further sinks, and the gas escapes from the shoulder into the waterway. Therefore, before assembly should be tested to check the protrusion, to ensure that the allowable range.
