1. Aging or damage of the cylinder liner seal: During long-term use, the cylinder liner seal will be eroded by high temperature, high pressure, engine oil and coolant, and gradually lose its elasticity and sealing performance.
2. There are cracks or sand holes in the engine body: This may be due to defects in the manufacturing process, or severe vibration, impact, etc. during use.
3. The cylinder head bolts are not tightened or the tightening torque is uneven: This will cause the seal between the cylinder head and the engine body to be loose, resulting in coolant leakage.
4. Radiator failure: For example, the radiator core tube is broken, the water tank cover is poorly sealed, etc.
5. Damage to the water pump seal: This will cause the coolant to leak from the water pump, and then may flow to the engine body.
6. Improper operation: If seawater or highly corrosive antifreeze is used, the waterway components of the diesel engine will be damaged.
Methods for dealing with diesel generator set leakage include:
1. Adhesive patching: If the water tank or water pipe is broken or there is a pore causing a small leak, you can clean the leaking part and apply adhesive patching.
2. Padding leak treatment method: If the leak is at the joint, you can add a thin plastic pad on both sides of the leak-proof ring and tighten it.
3. Liquid sealant leak treatment method: If the leak is caused by a defect in the solid gasket, you can apply liquid sealant to the cleaned solid gasket joint surface. After curing, it can form a uniform, stable, and continuously adhered peelable film gasket.
4. Paint flake liquid leak treatment method: If the leak is at the joint, you can soak the paint flakes in alcohol and apply them to the cleaned joint.
5. Anaerobic glue leak treatment method: If the leak is at the bolt, thread or screw hole, you can apply anaerobic glue to the cleaned part, which can quickly cure to form a film and fill the gap between the parts.
6. Dimension recovery glue leak treatment method: If the leakage is caused by wear of the mating parts, you can apply dimension recovery glue on the worn parts, wait for it to solidify and then perform mechanical processing to restore the geometric shape and matching accuracy of the parts.
