Abstract
The utility model relates to an air filtration system, in particular to a locomotive air filtration system. The problems that a paper filtering core of an original air filtration system of a Dongfeng 8B type locomotive is prone to being damaged and low in efficiency are solved. The locomotive air filtration system comprises an air filter and a double-layer filtering mesh fixed on a side body of a locomotive, an edge covering steel plate is arranged on the peripheral side of the double-layer filtering mesh, bolt holes are formed in the edge covering steel plate, bolts are arranged in the bolt holes, non-mesh fabric is arranged between the double-layer filtering mesh, and the double-layer filtering mesh is connected through the bolts. The locomotive air filtration system reduces economic consumption of a locomotive diesel engine and fuel consumption of the locomotive, and operating efficiency of the locomotive is improved.
Description
Technical field
The utility model relates to air filtration system, particularly a kind of locomotive air filtering system.
Background technique
Dust storm fills the air throughout the year in the dust storm area, sandstorm weather frequently appears, operating locomotive air filter filtering efficiency is low to make air short circuit occur, a large amount of sand and dust enter cylinder of diesel engine, cause cylinder jacket of diesel engine, piston heavy wear, and diesel combustion is bad, it is serious that lubricating oil participates in the burning after-burning, delivery temperature exceeds standard, and power reduces, and the problems such as increase diesel consumption often occur.
Diesel engine of locomotive is as power unit, and under high rotating speed, high mechanical load and heat load, its working condition is directly connected to the performance of locomotive power and the quality of economic performance.The heel and toe wear of cylinder, power descends, and the main cause that economic performance reduces causes owing to containing a large amount of sand and dust in the air inlet, and air-strainer plays conclusive effect to the air inlet quality.
The former air filtration system of Type DF 8B locomotive has adopted and has integrated the wall-hanging air filter structure of the separate unit of being used to formula filter cleaner and low-head air-strainer.The paper filter core cracky of this filtering system belongs to the filtering product of Single Medium, can't satisfy the requirement in strong wind sand ground district, and its not flame retarding cause easily the motorcycle safety accident.In installation process, also be prone to simultaneously because the situations such as the short circuit that causes dirty air not in place and box sealing are not tight are installed.
Summary of the invention
The utility model is the former air filtration system paper filter core of solution Type DF 8B locomotive cracky, inefficient problem, thereby a kind of locomotive air filtering system is provided.
The technological scheme that the utility model is taked is: a kind of locomotive air filtering system, comprise air-strainer, with the double-layer filtering net that is fixed in the locomotive lateral body, the all sides of double-layer filtering net are provided with the bound edge steel plate, the bound edge steel plate is provided with bolt hole, be provided with bolt in the bolt hole, be provided with between the double-layer filtering net without screen cloth, double-layer filtering net is bolted.
Without the long 52cm of screen cloth, wide 28cm, thick 2mm.
Bolt will be fixed in the double-layer filtering net on the locomotive lateral body without screen cloth, can stop effectively that without screen cloth most of sand and dust enter air-strainer, and the air quality of air system is improved effectively, thereby reduce the working load of air-strainer.
Compared with prior art, the beneficial effects of the utility model are: diesel engine piston before transforming, cylinder liner are kept the 1-2 month meeting sand and dust working life in season only, annually need to change cylinder sleeve, piston three to four times.After transforming with compare before, piston, cylinder liner increase the 3-5 month in working life, change cylinder sleeve, piston reduces to 2 times.So use the utility model to reduce the economy consumption of diesel engine of locomotive and the fuel consume of locomotive, improved the operational efficiency of locomotive.
Description of drawings
Fig. 1 is the utility model structural representation;
1-bolt among the figure, 2-double-layer filtering net, 3-be without screen cloth, 4-bound edge steel plate.
Embodiment
As shown in Figure 1, a kind of locomotive air filtering system, comprise air-strainer, with the double-layer filtering net 2 that is fixed in the locomotive lateral body, double-layer filtering net 2 all sides are provided with bound edge steel plate 4, and bound edge steel plate 4 is provided with bolt hole, is provided with bolt 1 in the bolt hole, be provided with between the double-layer filtering net 2 without screen cloth 3, double-layer filtering net 2 connects by bolt 1.
Without screen cloth 3 long 52cm, wide 28cm, thick 2mm.
Claims (2)
1. locomotive air filtering system, comprise air-strainer, it is characterized in that: also comprise the double-layer filtering net (2) that is fixed in the locomotive lateral body, the all sides of double-layer filtering net (2) are provided with bound edge steel plate (4), bound edge steel plate (4) is provided with bolt hole, be provided with bolt (1) in the bolt hole, be provided with between the double-layer filtering net (2) without screen cloth (3), double-layer filtering net (2) connects by bolt (1).
