How to prevent bubbles in the diesel generator set water tank

Air bubbles in the fuel tank of the Diesel Generator set are generally caused by the high pressure gas in the cylinder entering the cooling water channel. The causes and troubleshooting of hernia are as follows.

1. The cylinder head nut is not tightened according to the specified torque. If the torque is too small, the cylinder head is not pressed and the high pressure gas will break into the water channel. Tighten the cylinder head nut to the specified torque and retighten it periodically.

2. The cylinder gasket is used for too long, and it is washed out or burned, and the sealing performance is deteriorated, resulting in air leakage. Replace the new cylinder head gasket.

3. The flat surface of the cylinder head is not flat or deformed, resulting in air leakage. The cylinder head should be ground or replaced.

4. Improper assembly causes the cylinder shoulder to break and suffocate. Replace the cylinder liner with the specified method.

5. The height of the shoulder of the cylinder liner is not enough or the depth of the shoulder hole on the body is too large. After the cylinder is set into the body, the plane height of the protruding body is not enough, or even subsided, and the gas will break into the waterway from the shoulder. Therefore, it should be tested before assembly, check the amount of protrusion, and ensure that it is within the allowable range.
