Causes and Solutions for Water Leakage in Diesel Generator Sets

When a diesel generator set experiences the "three leaks": oil leakage, water leakage, and air leakage, it can easily lead to problems such as increased fuel consumption, reduced power, and accelerated wear of parts. Checking for these three leaks is a necessary step in the maintenance and pre - startup inspection of diesel generators. There are numerous reasons for the three leaks, which are too many to list in a single day. Today, let's focus on water leakage among the three. Water leakage in a diesel generator set may occur in the fresh - water pump, radiator, or water pipes. Dingbo Power will now specifically explain the solutions for water leakage in each component.

Causes of Water Leakage in Diesel Generator Sets

1.The radiator is damaged and leaking.

2.The rubber hoses of the radiator's inlet and outlet pipes are cracked, or the clamp screws are loose.

3.The drain valve is not tightly closed.

4.The water seal is damaged, the pump casing is cracked, or the gasket between the pump and the cylinder block is damaged.

Solutions for Abnormal Water Leakage in Diesel Generator Sets

1.If the connecting rubber hose is damaged or the fastening clamp is loose, simply replace the damaged hose or tighten the clamp.

2.If the upper or lower water chambers of the radiator or the radiator core tubes are cracked, simply repair the cracks by welding or bonding, or replace or weld a small number of leaking radiator tubes.

3.If the water - blocking ring of the cylinder liner is damaged and water leaks into the oil pan, causing the oil level to rise and the oil to become emulsified, Dingbo Power, the generator manufacturer, recommends simply replacing the damaged water - blocking ring.

4.If the cylinder head gasket is damaged, or there are sand holes or cracks in the cylinder liner and cylinder head, and water enters the cylinder, resulting in abnormal combustion in that cylinder and phenomena such as water spraying from the exhaust. Simply replace the damaged parts of the cylinder head and cylinder block with sand holes or cracks, or use Loctite adhesive for repair. When using the adhesive, scrape off the paint at the crack of the part before applying the glue, and add filler if necessary. If the water tank leaks and the water level in the tank drops, the generator set will also be unable to operate normally.
