How to Deal With Cracks in Perkins Diesel Generator Set?

Mar. 13, 2023

Since the cylinder block of the Perkins diesel generator set is cast, and the generator set will produce certain vibration during operation, the cylinder block may crack to some extent after the unit has been used for a long time. So, how should users handle this situation?

During the use of the Perkins diesel generator set body, cracks are likely to occur between the two cylinder liner seat holes, about 1cm below the body inspection hole and the inner wall of the body, and the upper plane of the body is also prone to deformation due to improper use of lubricating oil.

If the engine body of Perkins diesel generating set is cracked, it will lead to air leakage of the diesel engine, water ingress or oil leakage of the lubricating oil in the oil pan, and the Perkins diesel engine will not work normally. If the machine body is deformed, it will damage the relative position of the surface of the machine parts, the concentricity of the main bearing block hole, the parallelism of the main bearing block hole and the center line of the camshaft bearing block hole, the perpendicularity of the cylinder center line and the center line of the main bearing block hole, etc.

Cracks in the body of Perkins diesel genset are generally caused by improper use and maintenance of operators. For example, in cold areas, the cooling liquid of Perkins diesel engine was forgotten to be discharged during storage, and excessive scale accumulation caused local poor heat dissipation. Perkins diesel engine operates at high load for a long time, resulting in excessive thermal stress in the body. The operator suddenly added cold water into the water tank under the high temperature condition of the diesel engine. The body is impacted by a large external force.

Starlight will teach you several emergency handling methods:

First, use epoxy resin adhesive to bond the Perkins generator set. This process is relatively simple and easy to operate, but it is not resistant to high temperature. It will fall off after a long time, and the cylinder block will crack.

Secondly, the screw repair is applicable to the situation that the Perkins generator unit is not stressed, the strength requirement is small and the crack range is short. The quality is good, but it takes a long time to handle.

Third, use a patch plate for sealing, and add a patch plate for sealing at the position with little stress.

Fourth, weld repair. Repair with different welding processes according to size.

Fifthly, plugging agents are commonly used for plugging, such as water glass and inorganic coagulant.

If your Perkins generating set has cracks after a long time of use, Starlight recommends that you contact the manufacturer's technical personnel first, and use the most appropriate repair method according to the actual use situation. Do not disassemble it blindly to avoid waste or unnecessary damage.

Starlight Power was founded in 1974 and is one of the earliest manufacturers of generators and diesel generator sets in China. If you want get more information, please feel free to send email to sales@dieselgeneratortech.com we will pay highly attention on your question.
