How to Prevent Cavitation of Perkins Diesel Generator Set?

May. 05, 2023

Starlight manufacturers analyze how to prevent cavitation of Perkins diesel generator sets: people's lives now have a great demand for electricity, but we often encounter short-term power outages in our lives, which may not have a great impact on our daily life, but it has a greater impact on hospitals, factories, etc., especially hospitals, so many factories and hospitals choose to purchase diesel generator sets, However, due to the low frequency of use, many knowledge is not well understood. Today, Jiangsu Starlight Power Generation Equipment Co., Ltd. will share with you the problem of Perkins diesel generator set cavitation and how to prevent it.

Cavitation is that the coolant on the surface of wet cylinder liner of Perkins diesel generator set is divided into several pinholes, and gradually expands and deepens, finally forming a deep hole or crack. Jiangsu Starlight Power Generation Equipment Co., Ltd. believes that it is caused by high-frequency vibration of cylinder liner. So, how to prevent cavitation of Perkins diesel generator set?


1. Factors of use: The temperature of the coolant is the most prone to cavitation, ranging from 40 to 60. Therefore, during operation, the coolant should be maintained at the normal operating temperature (80 ℃ -85 ℃). The coolant (liquid) provided by the manufacturer with non hardened water or cooling water contains more impurities. Experiments have shown that hard water contains salts and alkali several times faster than clean soft water. The suggestion given by Jiangsu Starlight Power Generation Equipment Co., Ltd. is to reduce idle time, overload, and overload operation time. Replenish fuel to reduce the loss of Perkins diesel generator set due to rough combustion according to regulations.


2. Maintenance factors: The need to replace the coolant, clean the cooling system in a timely manner, and maintain the cooling system in good technical condition. According to regulations, the fuel supply advance angle and fuel system components should be adjusted to maintain fuel system performance and reduce the harm caused by abnormal combustion. Jiangsu Starlight Power Generation Equipment Co., Ltd. believes in maintaining good cylinder fit clearance, crankshaft bearing clearance, and connecting rod bearing clearance to reduce cylinder knock and vibration. When installing parts such as cylinders, pistons, connecting rods, etc., try to meet the requirements of verticality and parallelism as much as possible, and reduce the impact on cylinder liner piston abnormalities.


3. Production factor: Jiangsu Starlight Power Generation Equipment Co., Ltd. suggested that the water jacket side wall of Perkins diesel generator set be coated with anti cavitation materials and damping materials. The hardness of the outer surface of the cylinder liner has been increased, and the surface roughness should be reduced as much as possible by selecting materials with strong cavitation resistance. Choose to increase the stiffness of the cylinder liner wall thickness to avoid resonance.
