China is vast in territory, the weather conditions difference of each department, and the temperature difference is very big.Require internal combustion locomotive in ± 40 ℃ ambient temperature range, normally to move in the NBS " internal combustion locomotive general technical specifications ".But want internal combustion locomotive should be under+40 ℃ sweltering hot weather normally operation, normally move at-40 ℃ severe cold weather again, this is to " heart " of internal combustion locomotive---the power usefulness of diesel engine has caused very big difficulty.Diesel engine full power operation is no problem in severe cold weather, but is higher than in ambient temperature+summer of 30 ℃, if the operation of diesel engine full power will be shortened the mechanical working life of diesel engine greatly.
On the present internal combustion locomotive in order to solve the operation difficult problem of diesel engine under various ambient temperatures, the method that adopts is to be that standard is set limit value to diesel engine power with high ambient temperature, this makes diesel engine power can not get abundant utilization, and the hauling ability of locomotive is also had a greatly reduced quality.
The model utility content
The purpose of this utility model is: the diesel engine that solves existing internal combustion locomotive is not because of there being the correction of power temperature, cause diesel engine when ambient temperature is low " low load with strong power ", the difficult problem that hauling ability is not good, a kind of diesel engine of locomotive output power temperature update the system that can regulate the diesel engine output power according to ambient temperature is provided, not only guarantee the working life of diesel engine but also improved the effect of diesel engine, promoted the hauling ability of locomotive simultaneously.
For realizing the purpose of this utility model, in vent external environment temperature sensor is set, according to its detection and pass to the ambient temperature signal of microprocessor, microprocessor is given the main generator excitation controlling device according to power correction formula output regulation signal, regulate the exciting voltage or the electric current of main generator, thereby the regulator generator output power is regulated the output power of diesel engine with this.
Concrete technological scheme is as follows:
Diesel engine of locomotive output power temperature update the system comprises the microprocessor and the connected main generator excitation controlling device that are arranged in the diesel engine power regulating system, also comprises being arranged on the outer environment temperature sensor one that is connected with microprocessor of locomotive.
Described temperature correcting device also comprises and is arranged on the outer environment temperature sensor two that is connected with microprocessor of locomotive.
Described environment temperature sensor one is arranged on vehicle frame place, locomotive cab below.
Described environment temperature sensor two is arranged on vehicle frame place, locomotive cab below.
Be arranged on vehicle frame place, locomotive cab below, the direct ambient temperature in the perception external world, environment temperature sensor one and environment temperature sensor two backup each other, and improve the reliability of ambient temperature detection.
Described microprocessor also is connected with intercooler entering water temp sensor.
Described microprocessor also is connected with display screen.
The utility model is provided with environment temperature sensor outside locomotive, the temperature of direct testing environment, detected ambient temperature signal is delivered to microprocessor, microprocessor is regulated formula according to power correction and is regulated the power that export, and the relation of this power being pressed main generator output power and its exciting voltage or electric current, be converted to exciting voltage or current controling signal, pass to the main generator excitation controlling device by microprocessor, excitation system by regulating main generator is regulating the output power of main generator, thus the output power of regulating diesel engine.
As seen, adopt the utility model of said structure, compared with prior art, can revise diesel engine power output automatically according to ambient temperature, make diesel engine under high temperature, low temperature, carry out power adjustments, both guaranteed the working life of diesel engine, improved the effect of diesel engine again, the waste of having avoided its " low load with strong power " to cause has also promoted the hauling ability of locomotive simultaneously.
Description of drawings
Fig. 1 is a structured flowchart of the present utility model.
Embodiment
Below in conjunction with specific embodiments and the drawings the utility model is further described.
As shown in Figure 1, diesel engine of locomotive output power temperature update the system comprises environment temperature sensor one and the environment temperature sensor two that is arranged on vehicle frame place, locomotive cab below, these two sensors all are connected with the microprocessor of diesel engine power regulating system, and these two sensors backup each other, to improve the reliability of testing environment temperature.
Above-mentioned microprocessor also is connected with intercooler entering water temp sensor, display screen, main generator excitation controlling device respectively.
In microprocessor, also store CIMAC power correction formula.Formula is
P
x＝α×P
r
α＝1.105×K-0.105
In the formula: P
x---locomotive should send power, kW under Environmental Conditions
P
r---entrucking power, kW
α---power correction system
K---indicated power ratio
t
x---locomotive Environmental Conditions temperature, ℃
Modified basis:
1, power correction is by above-mentioned CIMAC formula;
2, the basic power of power correction (being calibration power) is the entrucking power of diesel engine.Standard environment is height above sea level 700m, and ambient temperature is+30 ℃;
When 3, ambient temperature surpasses+30 ℃, the beginning power correction;
4, according to service condition, formula is not considered the pressure change factor;
When 5, calculating, the intercooler water temperature is by ambient temperature+25 ℃, and mechanical efficiency elects 0.87 as;
6, power only considers to be adapted to ambient temperature+40 ℃, when ambient temperature surpasses+40 ℃, by+40 ℃ of corrections.
If environment temperature sensor one and environment temperature sensor two all lost efficacy, simultaneously the intercooler entering water temp reach+60 ℃ the time, diesel engine power is by ambient temperature+40 ℃ correction.
The working principle of diesel engine of locomotive output power temperature update the system is as follows:
Environment temperature sensor one detects ambient temperature, be converted to electrical signal transfer and give microprocessor, if ambient temperature is above+30 ℃, microprocessor begins the starting power correction, and press the CIMAC formula, calculate locomotive and under this ambient temperature, should send power, and according to the relation between main generator excitation electric current and the power, be scaled the field current that it needs, the field current control signal that should send power passes to the main generator excitation controlling device to regulate the field current of main generator, thereby regulate the output power of main generator, and then regulate the output power of diesel engine, reach purpose according to temperature correction diesel engine output power.
