Detailed description of the invention
As Fig. 1, be applicable to a high efficiency fuel burner for plateau plain, the present invention is characterised in that, this burner employs corresponding different altitude height atmospheric density correction chart, when being in differing heights, the oil pump of burner can control fuel feeding by the optimization fuel delivery corresponding according to altimeter; And when burner operation is under condition of different temperatures, burner, by built-in sensor air density information, adopts intake corresponding with it and fuel delivery reduced parameter to calculate, and determines the fuel feeding information that oil pump is corresponding with it;
Described intake, for motor often revolve turn around air inflow and motor speed long-pending;
Described fuel delivery is the long-pending fuel delivery be in the unit interval of operating frequency in every pulse oil inlet quantity of oil pump and time per unit; Wherein, every pulse oil inlet quantity of oil pump is basic fixing.
Use of the present invention corresponding different altitude height atmospheric density correction chart is that the numerical value of atmospheric density under Different Altitude and temperature conditions is made data query table, namely inquire about in advance when the burner is in operation and correction air density values, after environment height above sea level and temperature are determined, the density of air then according to height above sea level and the temperature conditions of correspondence, with the most similar Query Result for reference to carrying out calculating and revising.
As Fig. 2, this burner adopts electromagnetic wave detecting rotational speed system, measures the rotating speed of motor.This system is medium with electromagnetic wave, fixed support configures electromagnetic wave transmitter, motor shaft configures reflector plate, and when motor shaft rotates a circle, namely reflection electromagnetic wave once; Configure one piece of electromagnetic wave receiver in place, when reflection of electromagnetic wave is on receiver, namely count once, thus the rotation number of turns of perception motor, and then record diesel fuel burner motor speed measurement device.
Specific features of the present invention is:
conversion relation between blower fan intake and blower motor rotating speed, explains the compensation method that altitude change and variations in temperature are revised
The motor speed of blower fan intake and blower fan is directly proportional, and flabellum blade profile and the air channel back pressure of the intake that blower motor often turns around and blower fan are closely related, and is exactly briefly relevant with blower fan and blower fan applied environment, this be by blower fan and environment for use determined.Because environment for use is determined, blower fan is determined, the air quantity that the motor of blower fan often turns around also is determined, so the linear relationship under just can being based upon certain density conditions between intake and the motor speed of blower fan.
Be it can also be seen that by above-mentioned explanation link, if atmospheric density there occurs change, then still likely cause actual intake to change, so need to consider the changing factor of density.And cause the principal element of air density change to be pressure and temperature, when pressure reduces or temperature raises, all cause atmospheric density to decline; Contrary then cause atmospheric density to rise.Air pressure variations maximum effect factor under atmospheric environment is height above sea level, so for the numerical value of atmospheric density under certain height above sea level and temperature conditions, can work out a form according to the empirical data of environment temperature and height above sea level, for inquiring about and providing reference.After environment height above sea level and temperature are determined, the density of air then according to height above sea level and the temperature conditions of correspondence, with the most similar Query Result for reference to carrying out calculating and revising.This concrete calculating and modification method a lot, can the calculating such as cross-correlation method be adopted.
Can also fitting process be adopted, namely adopt the linear curve fit atmospheric density of multistage with the complex nonlinear rule of height above sea level and variations in temperature.After environment height above sea level and temperature parameter are determined, height above sea level and temperature parameter can be substituted in corresponding applicable linearity curve computing formula, thus the atmospheric density correction value under trying to achieve respective conditions.
The total wind supply quantity of blower fan calculates, and amasss with blower motor rotating speed is for motor often revolves the intake that turns around.
about the computational methods of oil pump feed amount
About the calculating of fuel delivery, every pulse oil inlet quantity of oil pump is again basic fixing, the long-pending pump oil mass that be unit interval in operating frequency in time per unit.
about the guideline of the matching relationship between wind-oil match ratio
About the basis of fuel delivery, can be 1.2 ~ 1.4 to allocate with reference to the best actual wind oil equivalent proportioning of diesel combustion.When real work excess air ratio is less than 1.2, then reduces fuel delivery or strengthen wind supply quantity; When real work excess air ratio is greater than 1.4, then strengthens fuel delivery or reduce wind supply quantity.
about the explanation of polyline fitting process or look-up table
As previously mentioned, atmospheric density, by various factors, presents non-linear rule.Use a complicated algorithm accurately to describe the density of air, engineering there is no need.Conventional following two kinds of algorithms carry out the engineering calculation numerical value of approximate calculation atmospheric density.
Polyline fitting algorithm, namely adopts the linear curve fit atmospheric density of multistage with the complex nonlinear rule of height above sea level and variations in temperature.After environment height above sea level and temperature parameter are determined, above-mentioned two parameters can be substituted in corresponding applicable linearity curve computing formula, thus the atmospheric density corrected Calculation value under trying to achieve respective conditions.
Look-up table is the method for another kind of estimation atmospheric density, namely in memory, the numerical value of atmospheric density under Different Altitude and temperature conditions is made data query table, namely inquire about in advance when the burner is in operation and correction air density values, after environment height above sea level and temperature are determined, the density of air then according to height above sea level and the temperature conditions of correspondence, with the most similar Query Result for reference to carrying out calculating and revising.This concrete calculating and modification method a lot, the estimations such as contiguous point value cross-correlation method can be adopted.
conversion relation between rotation speed of fan and operation of oil pump frequency
By noted earlier, we can obtain such concept, under the system namely determined and environment for use condition, can know definite blower fan intake information by the rotating speed of blower motor.According to wind, oily matching relationship, the best pump oil mass of oil pump is also determined.
In the every pulse of known oil pump under oil condition, only need the operating frequency determining oil pump.
Namely the numerical relation between blower motor rotating speed and operation of oil pump frequency is determined.In actual engineering use procedure, namely by setting up the conversion relation that a linear relation is determined between the two, also can add some correction factor.
This relational expression is closely related with buner system and operation of oil pump characteristic, when more scavenge oil pump or blower fan, or during the use back pressure situation of adjustment burner, conversion relation formula all can be made to change.Here inconvenience provide definite equation because they and be not suitable for all situations, only can provide explanatory note here.
The elevation adaptive mode of burner is except using electromagnetic wave detecting rotational speed system, and can be that other measure the device of motor (blower fan) axle rotating speed, as the Hall effect pipe of axle tachometric survey, can also be counter of mechanical separator speed etc.
