Description
Technical field
The utility model relates to a kind of diesel engine of diesel locomotive air filtration unit, prevents that mainly the sand and dust material from entering diesel engine of diesel locomotive and the heavy wear diesel engine part.
Background technique
Domestic railway line many places, Xinjiang belong to typical continental climate in the Gobi desert desert.In 1 year, arranged the dust storm phase about 6 months, the wind speed height, seasonal strong, sand content is high, railway line is subjected to the infringement of dust storm often.Sandstorm weather is not rarely seen Xinjiang yet, in case arrive then be sand and dust all over the sky, even sand and dust bury individual segment with rail sometimes, dust storm often floods whole train.After locomotive goes back to locomotive depot, between operator cabin, electric equipment compartment, machinery, each one of chilling room and diesel engine air filtering internal system sand and dust bulk deposition.Because the defective in the existing east wind 4B type locomotive diesel engine air filtration unit design, sand and dust are easy to enter diesel engine frame.The main component of sand and dust is quartz sands, accounts for the 65%-95% of sand and dust total amount, and its hardness is considerably beyond the diesel engine of locomotive main parts size.Diesel engine of diesel locomotive is as power plant, and its cylinder liner, piston, piston ring, connecting rod, bent axle are main workpieces, and entering in a large number of sand and dust makes these parts be subjected to heavy wear.This has had a strong impact on stability, the power performance of diesel engine of diesel locomotive in dust storm area in vogue operation, also shortened the working life of diesel engine, cause the deterioration of diesel combustion operating mode, power to descend, the consumption of diesel oil and machine oil is significantly risen, increased locomotive operation cost, the cost of overhaul.
East wind 4B type locomotive diesel engine air filtration unit adopts three grades of depuration structures: the first order is 4 groups of steel wires or " V " shape filter screen, and effect is to remove the oarse-grained grains of sand, stops foreign material such as sleet and leaf, because mesh is bigger, acts on very limited; The second level is cyclone air cleaner, include 21 independently the whirlwind tube can remove the dirt sand and the moisture content of air inlet small particles, its dust accumulation of impurities of separating needs the labor cleaning in the ash collection slot of cyclone filter bottom; The third level is that the effect of papery filter cleaner is the above sand and dust of 10um in the filtering air, the fixing paper filter element that holds up of the shared carriage of a plurality of papery filter elements, different in size stressed yielding because of paper filter element with carriage, cause paper filter element air outlet rubber seal to press unreal and air leakage phenomena.
In sum, because the defective in the east wind 4B type locomotive diesel engine air filtration unit design, add poorly sealed, low at dust storm section filtering efficiency, air filtration unit is inner often assembles a large amount of sand and dust, causes that cleaning period is short, frequency is high, the cleaning work difficulty is big; Diesel engine critical piece serious wear, working life is short, and repair rate height, oil consumption are increased.Finally make locomotive be difficult to adapt to the service condition in dust storm area, the cost of overhaul, operating cost all significantly improve.
The model utility content
For overcoming the defective of the former air filtration unit of east wind 4B type locomotive diesel engine at project organization, improve sand and dust, contaminant filter and air filtering effect, reduce the wearing and tearing of diesel engine part, strengthen operation adaptability, the stability of locomotive in the dust storm area, reduce locomotive operation cost, maintenance workload, the utility model provides a kind of improved diesel engine of diesel locomotive air filtration unit.
The utility model diesel engine of diesel locomotive air filtration unit mainly is made of compartment airstrainer, whirlwind tube, filter core carriage, filter core, filter screen case, steel plate filter screen, intake duct, pressurizer, the husky hole of row, maintenance valve.The compartment airstrainer adopts between wire gaze and clamps the fabric nonwoven cloth structure, and is installed in outside the compartment; Filter core carriage one side is installed near the car body inner seal, and another side covers the iron plate sealing; Filter core carriage top design opening, tapped filter core fixed base, also designing on the filter core carriage has inverse inhalation type to arrange husky hole, and the below design that inverse inhalation type is arranged husky hole has vertical baffle plate, oblique baffle plate, and vertical baffle plate base is higher than oblique baffle plate base; The filter core configuration design becomes round barrel shape, the vertical vertically folding of filter paper, and the design of filter core upper end has outside thread and opening, the bottom sealing of rubber material of filter core bottom; Filter core is fixed on the filter core carriage by the outside thread on top, internal thread on the filter core fixed base; The filter screen case is installed in filter core carriage top, and design has the steel plate filter screen in the filter screen case, and the steel plate filter screen adopts the metal screen stack compacting of different size mesh to form; The filter screen case is connected by intake duct with pressurized machine; Compartment exterior bottom design has the husky hole of row, and it is connected with filter core carriage bottom flushing of sediment hole; Corresponding car body inner side with the compartment airstrainer is equipped with the whirlwind tube, and whirlwind tube bottom opening is arranged husky hole with the inverse inhalation type on the filter core carriage and is connected.
Because after locomotive operation was of long duration, being covered with dust all on the steel plate filter screen needed to clean with greasy dirt, is convenient the cleaning, and the maintenance valve of free switch is arranged near the Position Design of steel plate filter screen on the filter screen casing.Open the maintenance valve, the steel plate filter screen is just unloaded cleaning down, is changed from guide groove easily.
In addition,, reduce the shake of filter core when locomotive operation, outside filter core filter paper, twine wire gaze for gaining in strength.
The working principle of the utility model diesel engine of diesel locomotive air filtration unit is: air is gone into the whirlwind tube by compartment air-filtering net filtration is laggard, and this moment, the sand and dust of big material were filtered outside the compartment, but short grained dust still can enter.Locomotive produces whirlwind in when operation in the whirlwind tube, short grained dust under the whirlwind effect earlier after the inverse inhalation type row Sha Konghou on the whirlwind tube bottom opening, filter core carriage drops on filter core carriage bottom.In locomotive operation, " vacuum " that air flows forms incited somebody to action, and stays the sand and dust of filter core carriage bottom and take away after filtering.Air successively passes through filter core, steel plate strainer filtering again after the whirlwind tube is through purification, be pressurized by intake duct at last to enter in the diesel engine of diesel locomotive body after device pressurizes.By filtration repeatedly, the air inlet quality is greatly improved.Because the filter paper of filter core is vertical folding, dust granule also is difficult for adhering to and drops and be discharged from filter core carriage bottom.
After using the utility model diesel engine of diesel locomotive air filtration unit, strengthened air filtering effect and engine adaptability, stability in the operation of windy and dusty area, reduced operating cost, prolong diesel engine work parts working life and maintenance maintenance period, reduced maintenance workload.Simultaneously, have simple in structure, the characteristics easily of overhauling are installed.
