Generator manufacturers teach you to check the diesel generator set air intake system leakage problem
June 23, 2022
Diesel generator sets in the long-term use of the process, inevitably encounter one or more problems, including "three leaks" (oil leakage, gas leakage, water leakage) problem is extremely harmful, will make the technical state of diesel generator sets rapidly deteriorate, so users must pay attention to the diesel generator sets "three leaks Therefore, users must pay attention to the diesel generator set "three leaks" problem, this top Bo power focus on introducing you to the "gas leakage" problem, which has a direct link with the diesel generator set intake and exhaust system.
Diesel generator intake and exhaust system
The intake and exhaust system of diesel generator set is mainly composed of air filter, intake and exhaust pipe and muffler, the main role of air filter is to filter out the dust and impurities in the air, the clean air into the cylinder to reduce the piston connecting rod set, gas distribution mechanism and cylinder wear; the main role of intake and exhaust pipe is to guide the fresh air into the cylinder and exhaust gas from the cylinder, intake and exhaust pipe are bolted to the The intake and exhaust pipes are bolted to the cylinders (top-mounted gas distribution mechanism) and are equipped with sealing gaskets at their joints to prevent air leakage; the muffler is generally made of thin steel plate stamping and welding, its role is to reduce exhaust noise and eliminate the sparks in the exhaust gas.
The normal work of the diesel generator set intake and exhaust system is of great significance to the performance of the unit. Once the diesel generator set intake system leaks, it will make the air enter the diesel engine cylinder directly without filtering, and the dust and impurities in the air will enter the cylinder and cause early wear of the cylinder liner, piston and piston ring and other parts, resulting in a decrease in the power of the diesel generator set and an increase in fuel consumption, so we must To ensure that the air intake system does not leak, so how to check whether the daily user probable air intake system leaks? Top Bo power for your tips.
1、Check whether the air intake hose has cracks or perforations, whether the clamp and bolt are loose, and if abnormalities are found, they should be replaced in time, and if the clamp or bolt is loose, they should be tightened in time to ensure that the air intake pipe cannot leak.
2, check and maintain the intercooler, check with the naked eye whether there are cracks, perforations or other damage to the intake intercooler inlet and outlet chambers, tubes, heat sinks, etc.
3、Check the air filter
Check the air filter resistance value during calibration, when the value exceeds (supercharged and supercharged cold models: 6.2Kpa, naturally aspirated models: 5.0Kpa), the air filter components should be replaced.
Diesel generator set "three leaks" phenomenon will produce many hazards, the user must pay attention to, timely inspection and removal, diesel generator set of the intake and exhaust system is an important part of the unit, the technical state of its good or bad directly affects the performance and service life of the generator set, so it is very important to do a good job of diesel generator set intake and exhaust system inspection. Therefore, it is very important to do a good job of checking the diesel generator intake and exhaust system.
The most neglected inspection items of diesel generator sets: wiring harness inspection
