(1) sideshake of diesel engine piston first annular groove transfinites, and has the cylinder-barrel ellipticty of nearly 1/3 to transfinite.After collecting the carbon distribution at abrasion position, melt, filtering, dry rear discovery to the solid portion of remnants, main component is that iron is cut.By analysis, thinking that iron is cut is not cylinder sleeve abrasion things, but from diesel engine intake.
(2) pressurized machine discovery when carrying out Disintegration overhaul of diesel engine, pump impeller and turbine surfaces have obvious metal granule dust.A material dust on pump impeller surface is from air filter.
(3) intercooler finds in Disintegration overhaul process, there is a large amount of metal granule dust in air inlet section of jurisdiction, and cause air inlet not smooth, the dust in section of jurisdiction is mainly derived from air inlet.
On the other hand: industrial diesel locomotive air filter adopts cascade filtration (as shown in Figure 1), air filter system is primarily of v shape filter screen, and GE whirlwind air strainer and GE papery secondary filter form.The not filtration substantially of v shape filter screen, only prevents the foreign material blocking intake grills such as leaf.GE whirlwind air strainer is the assemblying body of 54 whirly cylinders, and this is as an independent casing, and lower box is dust collecting trough, and bottom land is provided with the dust exhaust port of 3 band rubber original papers, can regularly remove the dust collected in groove.Its working principle is: when ambient air flows through the blade passage of exterior cylinder with certain speed, and dust impurity contained in air falls into the dust collecting trough of lower box through centrifugal action.Air after dedusting enters secondary filter cleaner through inner cylinder.This mode is comparatively obvious for the larger particles effect be present in air, can reach the degree of filtration of more than 90% of regulation.But for the dust in air in smelter, the grains of sand, metal granule dust, enter the wind speed before cyclone cylinder and do not reach speed by dust a large amount of in centrifugal force separate air far away, one cyclonic filter cleaner is poor to the dust smoothing effect in air.
Papery secondary filter leans on the fibre gap that paper is intensive, and along with the increase of storage ash quantity, fibre gap is more and more less, and filtering particle is more and more thinner, and resistance is also increasing, as cleaning will block completely not in time.
When Dust Capacity runs up to a certain degree, except the blocking caused papery secondary filter, part dust is by under the pitch force of locomotive operation and the air-entry suction effect of diesel engine, come back in inlet air filtration process, downward single filter parts run, and add the filtration load of next stage filter.In the repeatedly car downforce wind purge of papery secondary filter, pore size filter will be made to become large under external force, density degree is uneven, will make like this big dust particle enter diesel engine suction tude in, reduce air quality, the improper abrasion of aggravation kinematic pair, reduce the working life of diesel engine part.
