Abstract
The invention provides a method for controlling louvers of a cooling chamber in an internal combustion locomotive. The method comprises the following steps of: detecting the water temperatures of high and low-temperature cooling systems of the locomotive respectively; when the water temperature of the high-temperature cooling system is higher than 70 DEG C or the water temperature of the low-temperature cooling system is higher than 40 DEG C, opening a side louver; otherwise, closing the side louvers; when the water temperature of the high-temperature cooling system is higher than 74 DEG C or the water temperature of the low-temperature cooling system is higher than 42 DEG C, opening a top louver and starting a cooling fan; otherwise, closing the top louver and stopping the cooling fan. According to the method, the times when opening or closing the pneumatic top louver and the pneumatic side louver of the cooling chamber are accurately controlled, a situation that the side louver is opened or closed after or before the top louver is opened or closed is avoided, and the cooling systems of the internal combustion locomotive can be close to an optimal working state to the hilt.
Description
Technical field
The present invention relates to a kind of diesel locomotive cooling room louver control method, belong to the railway locomotive technical field.
Background technology
Diesel locomotive cooling room operated by rotary motion has top louver and the inside air-breathing side louver of outside exhaust.The top louver normally relies on cooling fan to rotate the blast that produces and blows blade open, realizes the unlatching of top louver; After cooling fan stopped operating, blade relied on gravity to close.And the side louver for adopting hydrostatic motor to drive the locomotive of cooling fan, is the mode that high pressure oil is provided by hydrostatic pressure system.Arrive the side louver by a branch road in parallel in the pipeline of hydrostatic pressure system, install a temperature control valve additional at branch road, when temperature control valve reaches open temp, temperature control valve is opened, the high pressure oil that hydrostatic pressure system provides by pipeline to the oil cylinder fuel feeding on the side louver, oil cylinder pulling louver is opened, otherwise then closes.Because the open temp scope of temperature control valve is larger, too lag or lead situation about opening in the top louver of side louver often can appear.The side louver is opened too and is lagged behind, and cooling fan is worked already, and this can make chilling room produce negative pressure, and the hot blast suction radiator with power room impacts locomotive operation; The side louver is opened too leading, and in the high and cold situation in the external world, a large amount of cold airs pour into, and can make diesel engine be difficult to reach optimum Working.
Summary of the invention
Purpose of the present invention overcomes the deficiency of above-mentioned prior art exactly, a kind of diesel locomotive cooling room louver control method is provided, accurately the switching opportunity of control cooling room pneumatic top louver and aerodynamic side louver, make diesel engine of diesel locomotive to greatest extent near optimum Working.
The object of the present invention is achieved like this: a kind of diesel locomotive cooling room louver control method is characterized in that taking the following step:
A. detect respectively locomotive high and low temperature cooling system water temperature;
B. when the High-temperature cooling system water temperature is higher than 70 ℃ or low-temperature cooling system water temperature and is higher than 40 ℃, open the side louver; Otherwise close the side louver;
C. when the High-temperature cooling system water temperature is higher than 74 ℃ or low-temperature cooling system water temperature and is higher than 42 ℃, open the top louver, cooling fan is started working simultaneously; Otherwise close the top louver, cooling fan quits work.
The solution of the present invention is accurately controlled switching opportunity of cooling room pneumatic top louver and aerodynamic side louver, avoided the side louver too lag or lead make diesel engine of diesel locomotive to greatest extent near optimum Working in the situation that the top louver opens and closes.
Description of drawings
Fig. 1 is the louver control actuating unit principle schematic of the embodiment of the invention.
Fig. 2 is the louver control principle block diagram of the embodiment of the invention.
Be labeled as among the figure: the 1-microcomputer control unit, the 2-solenoid directional control valve, 3-louver cylinder, 4-sockets cock, the 5-electromagnetic valve, the 6-sebific duct, 7-top louver, 8-sockets cock, 9-pressure sensor, 10-blast main, 11-side louver.
The specific embodiment
For the purpose, technical scheme and the advantage that make the embodiment of the invention clearer, below in conjunction with the accompanying drawing in the embodiment of the invention, technical scheme in the embodiment of the invention is clearly and completely described, obviously, described embodiment is the present invention's part embodiment, rather than whole embodiment.Based on the embodiment among the present invention, those of ordinary skills belong to the scope of protection of the invention not making the every other embodiment that obtains under the creative work prerequisite.
Referring to Fig. 1, cooling room Pneumatic shutters control actuating unit by microcomputer control unit 1, solenoid directional control valve (electromagnetic valve) 2, louver cylinder 3, socket cock 4 and connecting line etc. and form, two solenoid directional control valves 2 and an electromagnetic valve 5 are connected in parallel on the blast main 10, control respectively the unlatching of the side louver 11 of both sides and top louver 7 and close.
Referring to Fig. 2, in locomotive High-temperature cooling system, when cooling water temperature is higher than 70 ℃, 2 actions of microcomputer controlled electro magnetic change-over valve, the blast main pressurized air enters cylinder from the rear end, pushing piston, piston rod is protruding, moves towards the direction of opening the side louver, opens side louver 11.When side louver 11 is opened, behind the fan running or locomotive load reduce, if locomotive High-temperature cooling water temperature descends gradually, drop to when being lower than 70 ℃, 2 commutations of microcomputer controlled electro magnetic change-over valve, the exhaust of cylinder rear end, front end (piston rod external part) air inlet makes the piston rod indentation, move towards closing the louver direction, order about side louver 11 and close.
In the locomotive low-temperature cooling system, when cooling water temperature is higher than 40 ℃, 2 actions of microcomputer controlled electro magnetic change-over valve, the blast main pressurized air enters the cylinder rear end, and pushing piston moves to the direction of opening the side louver, opens side louver 11.When the side louver is opened, behind the fan running or locomotive load reduce, if the locomotive coolant water temperature descends gradually, drop to when being lower than 40 ℃, 2 commutations of microcomputer controlled electro magnetic change-over valve, the exhaust of cylinder rear end, front end airflow, piston is moved towards closing the louver direction, order about side louver 11 and close.
In like manner, when high-temperature water water temperature 〉=74 ℃ or water at low temperature water temperature 〉=42 ℃, the electromagnetic valve 5 of control top louver 7 is opened, otherwise then closes.A pressure sensor 9 was installed before electromagnetic valve 5 and top louver, and pressure sensor 9 is connected with microcomputer control unit 1.Can not use or pressure sensor during to driver's cab insufficient pressure signal if electromagnetic valve 5 hinders for some reason, the cock 8 that sockets can be manually opened in parallel with electromagnetic valve 5 makes top louver 7 smooth opening.
It should be noted that at last: above embodiment only in order to technical scheme of the present invention to be described, is not intended to limit; Although with reference to previous embodiment the present invention is had been described in detail, those of ordinary skill in the art is to be understood that: it still can be made amendment to the technical scheme that aforementioned each embodiment puts down in writing, and perhaps part technical characterictic wherein is equal to replacement; And these modifications or replacement do not make the essence of appropriate technical solution break away from the spirit and scope of various embodiments of the present invention technical scheme.
