Description
Technical field
The present invention relates to a kind of electric locomotive air system defroster and application methods.
Background technique
Electric locomotive air system includes the equipment such as air compressor machine, cylinder, air-supply valve, threeway non-return valve.When compressor operation,
A certain amount of water is inherently generated, is generally released water by cylinder drain valve and air pipe line blowdown valve, it is ensured that air system
System operates normally.North of china in winter is cold, and the water that air compressor machine generates cannot be discharged immediately, and air system equipment is blocked after freezing, is made
It is unable to run at locomotive.Such as: wind path is narrow in air-supply valve, most easily freezes, and part comparison is accurate, inner body pole after icing
It is easy to damage that air-supply valve is caused to be scrapped.Every year because air-supply valve icing causes trouble of shutdown up to 10 Yu Taici, the air-supply valve of damage up to 5
~6.Blowdown valve main function is exactly to discharge air system ponding, so winter easily occurs water and freezes, after freezing, and blowdown
Valve discharging valve will be freezing.Annual winter, freezing blowdown valve was up to more than 10 because blowdown valve drains not in time.
Therefore, it is badly in need of designing a kind of method to solve this problem.
Summary of the invention
In order to overcome the deficiencies of the prior art, the object of the present invention is to provide a kind of electric locomotive air system defroster and make
With method, water in air system is reduced and because blocking caused by freezing, it is ensured that electric locomotive air system normal work.
To achieve the above object, the invention is realized by the following technical scheme:
A kind of electric locomotive air system defroster, including air compressor machine, cylinder, air pipe line, air-supply valve, the air pipe line
On be connected with blowdown valve, air-supply valve, air compressor machine is equipped with cylinder, dust arrester, which is characterized in that the dust arrester be equipped with plus
Heat cover；Cylinder, air-supply valve are covered with electric insulation cover outside blowdown valve.
The heating mantles include resistance wire one, metal mesh shell, metal mesh inner casing, metal mesh shell and metal mesh inner casing
Between be equipped with thermal insulation material, resistance wire one is equipped in thermal insulation material.
The electric insulation cover includes resistance wire two, insulating layer, is equipped with resistance wire two in insulating layer.
The metal mesh inner casing is equipped with the temperature controller being connected with resistance wire.
The application method of electric locomotive air system defroster, air compressor machine air sucks dust arrester, when air passes through, heating
The heat of vaporization part steam generated is covered, then enters cylinder through air filter, is set the electric insulation cover on cylinder
Heat preservation is heated by electric insulation cover no matter under compressor operation or stoppage in transit state, prevents water in cylinder from freezing；After pressure
Air is assigned in each equipment through air-supply valve, and the electric insulation cover on air-supply valve prevents air-supply valve inner icing；Finally by row
Water in dirty valve discharge air pipe line, keeps the temperature through electric insulation cover, prevents blowdown valve water from freezing, water is smoothly discharged.
Compared with prior art, the beneficial effects of the present invention are:
By the setting of heating mantles and electric insulation cover, caused by preventing air system (air pipe line, cylinder, air-supply valve) from freezing
Trouble of shutdown.Blocking caused by preventing air system internal cause to freeze, it is ensured that electric locomotive air system works normally, and saves
Maintenance expense reduces personnel and overhauls intensity.
Detailed description of the invention

Fig. 2 is heating mantles structural schematic diagram.
Fig. 3 is electric heat insulation cover structure schematic diagram.
In figure: one 2- metal mesh shell 3- fixing bolt 4- power supply line 5- attaching plug 6- metal mesh of 1- resistance wire
Inner casing 7- dust arrester 8- heating mantles 9- insulating layer 10- resistance wire two.
Specific embodiment
The present invention is described in detail with reference to the accompanying drawings of the specification, it should be noted that implementation of the invention is unlimited
In the following embodiments and the accompanying drawings.
See Fig. 1-Fig. 3, a kind of electric locomotive air system defroster, including air compressor machine, cylinder, air pipe line, air-supply valve, institute
Blowdown valve, air-supply valve are connected on the air pipe line stated, air compressor machine is equipped with cylinder, dust arrester 7, which is characterized in that the collection
Dirt device 7 is equipped with heating mantles 8；Cylinder, air-supply valve are covered with electric insulation cover outside blowdown valve.
Heating mantles 8 include resistance wire 1, metal mesh shell 2, metal mesh inner casing 6, metal mesh shell 2 and metal mesh inner casing 6
Between be equipped with thermal insulation material, resistance wire 1 is equipped in thermal insulation material, metal mesh shell 2 and metal mesh inner casing 6 pass through fixing bolt
3 is fixed.
Electric insulation cover includes resistance wire 2 10, insulating layer 9, is equipped with resistance wire 2 10 in insulating layer 9.Insulating layer 9 can be by glass
Glass silk flosssilk wadding is made, it is also possible to which cotton-wadded quilt replaces.Resistance wire 1, resistance wire 2 10 are powered by power supply line 4 and attaching plug 5.
Metal mesh inner casing 6 is equipped with the temperature controller being connected with resistance wire, can prevent heating from causing the accidents such as damage equipment.
The antifreeze method of electric locomotive air system, air compressor machine air sucks dust arrester 7, when air passes through, what heating mantles 8 generated
Heat of vaporization major part steam reduces the water for entering air system.Then enter cylinder through air filter, be set
Electric insulation cover heat preservation on cylinder is heated by electric insulation cover, is prevented in cylinder no matter under compressor operation or stoppage in transit state
Water freezes.It is assigned in each equipment to the air after pressure through air-supply valve, the electric insulation cover on air-supply valve prevents inside air-supply valve
It freezes.Finally by the water in blowdown valve discharge air pipe line, is kept the temperature through electric insulation cover, prevent blowdown valve water from freezing, keep water suitable
Benefit discharge.
The setting that the present invention passes through heating mantles 8 and electric insulation cover, it is therefore prevented that air system (air pipe line, cylinder, air-supply valve)
Trouble of shutdown caused by freezing.Blocking caused by preventing air system internal cause to freeze, it is ensured that electric locomotive air system is normal
Work, saves maintenance expense, reduces personnel and overhauls intensity.
