Harm of Dust Entering Cummins Diesel Generator

Since the dust in the air of Cummins diesel generator is the main reason for the wear of moving parts such as cylinder head, piston, piston ring, valve and valve guide of the diesel engine, the more dust in the intake air of Cummins diesel generator, the faster the wear of Cummins diesel generator parts. The wear test of Cummins diesel generator shows that dust particles less than 1um have little impact on the engine, 99.5% of the dust particles will be discharged through the exhaust of Cummins diesel generator, and 1-10 μ The dust particles of m have obvious influence on the life of Cummins diesel generator.

If the size of dust particles in the air inlet of Cummins diesel generator is larger than the oil film thickness, it will seriously affect the life of Cummins diesel generator bearings, piston rings, etc. Carefully selecting the air filter of Cummins diesel generator is critical to the service life of Cummins diesel generator. According to different uses, the air filters of Cummins diesel generator can be divided into light air filters and heavy air filters. The filtration efficiency of light air filters is 99.5%, and the dirt absorption capacity is 6.4h/1.s. They are applicable to Cummins diesel generator and marine propulsion Cummins diesel generator working under low ambient air dust content, mainly composed of air filter cover, housing and filter element. The air of Cummins diesel generator enters each vortex tube tangentially from the small holes around the shell of vortex tube group, and the vortex tube generates strong vortex through the guide vane in the tube.

In the process of vortex and reversal of Cummins diesel generator, due to the centrifugal force of Cummins diesel generator, the air is empty, and the impurity particles mixed with water and dust are thrown to the vortex tube wall and below, fall into the dust collection disk of the air filter, and then discharge the dust from the disk gap or periodically. The airflow of Cummins diesel generator flows back from the bottom of the vortex tube, through its vent tube, and then into the shell of the air filter. The remaining light dust enters the inner filter element after being filtered by the microporous outer filter element or the main filter element, and the clean air from the safety filter element enters the combustion chamber of Cummins diesel generator after being cooled by the supercharger and Intercooler. For heavy-duty air filters, the air outlet should be frequently opened during use, and dust trays can be removed to release accumulated dust.
