Description
Technical field
This utility model relates to the gas handling system of a kind of oilless air compressor, the gas handling system of a kind of oilless air compressor for track traffic.
Background technology
Oilless air compressor serves a vital effect in track traffic, it typically is rail traffic vehicles and provides pneumatic system, is operated the brake of rail vehicle by pneumatic system.The structure of the gas handling system of current oilless air compressor is to arrange air filter in the suction end front of head, middle by breathing manifold connection crankcase with balance crankshaft case pressure, the air inlet of oilless air compressor is directly entered cylinder by air filter, air inlet after filtering can effectively reduce the wear intensity of air compressor, extends its service life.But this air intake structure there is also certain defect: owing to the gas phenomenon of piston type air compressor itself is obvious, air inflow is produced certain impact；Oilless air compressor does not has lubricating oil to cool down bearing, if there is no airflow in crankcase again, then the parts such as connecting rod, link pin and crankshaft bearing within crankcase can due to high temperature service life reduction；The air filter in rail traffic vehicles oilless air compressor gas handling system is applied typically to use cylindrical empty air filter at present, need when installing this cylindrical empty air filter to reserve bigger service clearance, cause air compressor structure the compactest, the small size space of rail traffic vehicles uses inconvenience.
Utility model content
The purpose of this utility model is just to provide the gas handling system of a kind of oilless air compressor for track traffic, with solve charge air flow pulsation present in the gas handling system of existing track traffic oilless air compressor substantially, the cooling effect that produces the parts in crankcase is poor and the bigger problem that takes up room.
This utility model is achieved in that
A kind of gas handling system of the oilless air compressor for track traffic, including:
Crankcase, is used for accommodating bent axle；
Air filter, for the air entered in cylinder is filtered, it is arranged on the side of described crankcase, connect with described crankcase, including housing and the filter element for crossing air filtering being arranged at described enclosure interior, the side connected with described crankcase of described housing is provided with the gas outlet connected with described crankcase, and the couple positioned opposite in described gas outlet has air inlet；
Air inlet pipe group, for being incorporated in cylinder by the clean gas entered in described crankcase, including two air inlet pipelines, the two ends of every described air inlet pipeline connect with cylinder and described crankcase respectively；
Inlet flange, is used for connecting described air filter and described crankcase, is arranged between described air filter and described crankcase, and its two ends connect with described air filter and described crankcase respectively.
The described filter element of described air filter uses multilayer planar formula filter element.
The described housing of described air filter is rectangular-shaped housing.
Surrounding in the described gas outlet of described housing is provided with some connecting holes for connecting described inlet flange.
Surrounding in the side of the side connected with described crankcase of described housing is provided with some installing holes for fixing described air filter position.
Two described air inlet pipelines are that diagonal is oppositely arranged.
The height residing for described air inlet of described air filter is less than the height residing for described gas outlet.
This utility model includes air filter, air inlet pipeline and inlet flange, air filter is connected with crankcase by suction flange, arranging of air inlet pipeline has connected crankcase and cylinder, so two-way can be divided to flow in cylinder by crankcase after air inlet being filtered by air filter, give the function of crankcase a kind of air inlet surge tank.When oilless air compressor group operates, each parts in crankcase can produce substantial amounts of heat due to friction, it cannot be cooled by traditional gas handling system, and air filter connects with crankcase in the gas handling system in this utility model, parts in crankcase can be cooled by clean gas after filtering, entering cylinder by air inlet pipeline the most again to do work, the whole process of circulation of such gas is more unobstructed, makes charge air flow ratio shallower.Additionally, the filter element of air filter is set to multi-layer plate-type filter element, reduce the space shared by air filter, enable air filter to be combined with crankcase dexterously.
Air filter is arranged on the lateral surface of crankcase by this utility model, instead of traditional cartridge filter, make use of the position of crankcase lateral surface cleverly, saved space, enhances the compactedness of air compressor structure.Meanwhile, by the connection of air filter and crankcase using crankcase as air inlet surge tank, the parts in crankcase can either be cooled, the pulsation phenomenon of charge air flow can be smoothed again to a certain extent.
