Specific analysis of the filter element function of the mini excavator:

The function test of the filter element has the following four aspects: 1 Flow resistance test, which measures the pressure loss of air activity. In the two original filter power experiments, you can calculate the dust collection capacity of the filter element. The dust removal rate of the conventional filter element should be above 99%. Can accumulate dust and accumulate output experiment. The accumulation of extra dust in the filter element forms a blockage and the air intake resistance increases. The air intake resistance that reduces engine output to 5% or fuel consumption to 5% is the limit required to clean or replace the filter element. ④In the original inhalation resistance test, the increased intake air volume must not exceed 3.2 kPa, otherwise the filter cartridge (the air intake volume, the additional filter element is the air intake volume required by the engine) will pass through the filter and pressure engine requirements of the intake port. The exit. There is a connection close to the barrier along with the orientation and cabin intake temperature and intake temperature, away from the barrier, intake manifold and intake demand and high-temperature components or as many as possible, but also avoid high-temperature gas from entering the cabin air inlet. The hot air is discharged smoothly, so the cabin temperature can be kept as low as possible. In addition to the engine itself, the ability to ensure the normal operation of the engine and ensure the quality of production is the power source of the hydraulic excavator. It protects the engine during the application of scientific and reasonable maintenance.

Scientific and reasonable maintenance is to estimate preventive inspection and preventive maintenance based on the actual operating conditions of the engine. After the engine intake, exhaust, and maintenance of the four smooth profile system thermal interaction analysis elements, the interaction of these four aspects is judged to be repaired or other parts have not been replaced. The original refuge restores performance and extends the life of the engine.
