Detailed Description
In order to make the objects, technical solutions and advantages of the present invention more apparent, the technical solutions of the present invention will be clearly and completely described below with reference to specific embodiments and corresponding drawings. It will be apparent that the described embodiments are only some, but not all, embodiments of the invention. All other embodiments, which can be made by those skilled in the art based on the embodiments of the invention without making any inventive effort, are intended to be within the scope of the invention.
As shown in fig. 1, an embodiment of the present invention provides a method for adjusting and controlling an injector, which at least includes steps 101 to 105 as follows:
step 101, obtaining initial working condition parameters corresponding to the types of parameters affecting the energy saving performance of the injector, and calculating the injection coefficient and the working efficiency parameters of the injector.
Specifically, the parameter types include, but are not limited to, at least two of an operating pressure, an injection pressure, and an outlet pressure of the injector.
In some service scenarios, when other indicators (for example, the working flow rate) of the injector are also required to be used as important indicators for evaluating the energy-saving performance of the injector, other indicators corresponding to the injector (for example, the working flow rate corresponding to the injector) may be calculated according to initial operating condition parameters corresponding to the types of parameters affecting the energy-saving performance of the injector.
It should be further noted that, the initial working condition parameters corresponding to the parameter types are not directly used as the basis for regulating the injector, but the initial working condition parameters corresponding to the parameter types are correspondingly processed through a series of subsequent processing steps to obtain the optimal working condition parameters with higher precision corresponding to the parameter types; therefore, the accuracy of the initial working condition parameters corresponding to the parameter types respectively can only influence the calculated amount of the technical scheme provided by the invention, and in order to reduce the calculated amount, the parameter types and the initial working condition parameters corresponding to the parameter types respectively can be determined by combining the working experience of the staff.
Step 102, determining the influence degree of the parameter type on the injection coefficient and the working efficiency parameter, and determining a target parameter type from the parameter types according to the influence degree corresponding to the parameter type.
For convenience of description, specific parameter types include working pressure, injection pressure and outlet pressure of the injector, and specific initial working condition parameters corresponding to the foregoing parameter types are a1, b1 and c 1; after important indexes such as injection coefficient and working efficiency parameters of the injector are calculated according to a1, b1 and c1, each initial working condition parameter can be transformed according to a certain rule, for example, under the condition that b1 and c1 are certain, taking the product of a1 and a preset numerical value as an increment of a1 to obtain a transformed working condition parameter a2 corresponding to working pressure, then calculating the injection coefficient and the working efficiency parameters of the injector under the working condition parameter combination according to a2, b1 and c1, and further calculating the injection coefficient variation T1 and the working efficiency parameter variation L1 of the injector under the working condition parameter combination relative to the injector under the working condition that a1, b1 and c1 are combined; then taking the product of b1 and a preset value as the increment of b1 under the condition that a1 and c1 are certain, obtaining a converted working condition parameter b2 corresponding to the injection pressure, calculating the injection coefficient and the working efficiency parameter of the injector under the working condition parameter combination according to a1, b2 and c1, and further calculating the injection coefficient variation T2 and the working efficiency parameter variation L2 of the injector under the combination of a1, b2 and c1 relative to the injector under the combination of a1, b1 and c 1; based on the similarity transformation flow, the injection coefficient variation T3 and the working efficiency parameter variation L3 of the injector under the combination of a1, b1 and c2 relative to the injector under the combination of a1, b1 and c1 can be obtained; it is easy to understand that, for each current parameter type, when the initial working condition parameters corresponding to other parameter types respectively remain unchanged, the initial working condition parameters corresponding to the current parameter types are converted according to a certain conversion rule, and the subsequent processing is performed to calculate the obtained injection coefficient variation and the working efficiency parameter variation, so that the influence degree of the current parameter type on important indexes such as the injection coefficient and the working efficiency parameter can be measured to a certain extent, and therefore, the influence degree of the working pressure, the injection pressure and the outlet pressure on the injection coefficient and the working efficiency parameter can be measured according to the variation combination [ T1, L1], [ T2, L2], [ T3, L3 ].
Obviously, in an actual service scene, for each parameter type, under the condition that initial working condition parameters corresponding to other parameter types are unchanged, iterative transformation is performed on the initial working condition parameters under the parameter type for a plurality of groups of injection coefficient variable quantities and working efficiency parameter variable quantities, and then the plurality of groups of injection coefficient variable quantities and working efficiency parameter variable quantities corresponding to each parameter type are comprehensively considered to obtain more accurate influence degrees corresponding to the parameter types.
The multiple parameter types generally interact with each other; for example, when working condition parameters corresponding to the working pressure, the injection pressure and the outlet pressure are a1, b1 and c1 in sequence, the influence degree of the injection pressure on the injection coefficient and the working efficiency parameter is Y1, and when working condition parameters corresponding to the working pressure, the injection pressure and the outlet pressure are a2, b1 and c1 in sequence, the influence degree of the injection pressure on the injection coefficient and the working efficiency parameter is Y2 different from Y1. Therefore, after the influence degree of the parameter types on the injection coefficient and the working efficiency parameter is obtained, at least two target parameter types can be further determined from the parameter types according to the influence degree corresponding to each parameter type, so that the mutual influence among a plurality of parameter types is comprehensively considered, and the fact that the optimal working condition parameters corresponding to each parameter type respectively can be obtained later is ensured to have higher precision. Specifically, the greater the influence degree of one parameter type on the injection coefficient and the working efficiency parameter, the greater the possibility that the one parameter type will affect each other with other parameter types, so in step 102, the determining, according to the influence degree corresponding to the parameter type, the target parameter type from the parameter types includes: and selecting at least two parameter types corresponding to the influence degrees respectively as target parameter types according to the order from big to small.
For example, when the working condition parameters corresponding to the working pressure, the injection pressure, the outlet pressure and other parameter types are a1, b1 and c1 in sequence, it is determined that the degrees of influence of the working pressure, the injection pressure, the outlet pressure and other parameter types on the injection coefficient and the working efficiency parameter are X1, X2 and X3 in sequence, and X2> X1> X3, then the injection pressure and the working pressure corresponding to each of X2 and X1 can be selected as the target parameter types according to the order from large to small. Obviously, the number of the target parameter types can be reasonably set according to actual service requirements.
It should be noted that, at least two target parameter types may be determined from the parameter types in other manners; for example, each parameter type greater than a preset threshold value in the calculated respective influence degrees is determined as the target parameter type.
Step 103, determining a parameter interval of the initial working condition parameter corresponding to the target parameter type.
Specifically, for each target parameter type, the parameter interval (the interval size is an empirical value) of the initial working condition parameter corresponding to the target parameter type may be determined by using the initial working condition parameter corresponding to the target parameter type as a median. For example, the initial working condition parameter corresponding to the working pressure is 0.9MPa, the initial working condition parameter corresponding to the injection pressure is 0.65MPa, the parameter interval corresponding to the working pressure with 0.9MPa as the median is determined to be 0.5 MPa-1.3 MPa by combining with the preset interval size corresponding to the working pressure of 0.8MPa, and the parameter interval with 0.65MPa as the median is determined to be 0.5 MPa-0.8 MPa by combining with the preset interval size corresponding to the injection pressure of 0.3 MPa.
Step 104, determining the optimal working condition parameters corresponding to the parameter types respectively according to the parameter intervals of the initial working condition parameters corresponding to the target parameter types.
As an embodiment, the parameter determining step 104 may include the following steps 1041 to 1043:
step 1041, extracting at least two sampling working condition parameters from the parameter interval of the initial working condition parameters corresponding to the target parameter types with a preset step length for each target parameter type.
For example, the target parameter type includes a working pressure, and the parameter interval corresponding to the working pressure is 0.5 MPa-1.3 MPa, and taking the example that the preset step length includes 0.1MPa, the 9 sampling condition parameters including 0.5MPa, 0.6MPa, 0.7MPa, 0.8MPa, 0.9MPa, 1.0MPa, 1.1MPa, 1.2MPa, 1.3MPa and the like can be extracted from the parameter interval corresponding to the working pressure; the target parameter type comprises injection pressure, the parameter interval corresponding to the injection pressure is 0.5-0.8 MPa, and taking the preset step length comprising 0.1MPa as an example, 4 sampling working condition parameters such as 0.5MPa, 0.6MPa, 0.7MPa, 0.8MPa and the like can be extracted from the parameter interval corresponding to the injection pressure.
Obviously, for each parameter type, the extraction of at least two sampling working condition parameters from the parameter interval corresponding to the target parameter type may be implemented in other manners, for example, randomly extracting a set number of sampling working condition parameters from the target parameter interval.
Step 1042, selecting a candidate working condition parameter from the at least two sampling working condition parameters corresponding to each target parameter type, and calculating a set of candidate injection coefficients and candidate working efficiency parameters of the injector according to the candidate working condition parameters corresponding to each target parameter type and the initial working condition parameters corresponding to the parameter types which are not determined to be target parameter types.
It is obvious that in the actual business scenario, step 1042 may be performed multiple times to obtain multiple sets of candidate injection coefficients and candidate working efficiency parameters.
For example, the parameter types determined as the target parameter types in the parameter types include a working pressure and an injection pressure, the parameter types not determined as the target parameter types include an outlet pressure, an initial working condition parameter corresponding to the outlet pressure is c1, and each sampling working condition parameter corresponding to the working pressure is specifically 0.5MPa, 0.6MPa, 0.7MPa, 0.8MPa, 0.9MPa, 1.0MPa, 1.1MPa, 1.2MPa, 1.3MPa, and each sampling working condition parameter corresponding to the injection pressure is specifically 0.5MPa, 0.6MPa, 0.7MPa, 0.8MPa; then, selecting one candidate working condition parameter from the sampling working condition parameters corresponding to the working pressure and the injection pressure respectively, and forming a working condition point by the two selected candidate working condition parameters and the initial working condition parameter c1 corresponding to the outlet pressure which is not determined as the target parameter type, so as to calculate a group of candidate injection coefficients and candidate working efficiency parameters corresponding to the injector when the injector operates under the working condition point; and executing the similar flow for multiple times, so as to obtain a group of candidate injection coefficients and candidate working efficiency parameters respectively corresponding to the injector when the injector operates at multiple different working condition points.
Step 1043, determining the optimal working condition parameters corresponding to the parameter types according to each group of candidate injection coefficients and candidate working efficiency parameters.
Specifically, for each set of the calculated candidate injection coefficient and candidate working efficiency parameter, the greater the candidate injection coefficient and candidate working efficiency parameter, the higher the energy efficiency of the injector when the injector operates with the working condition point corresponding to the set of the candidate injection coefficient and the candidate working efficiency parameter, that is, the higher the precision of the working condition parameter (candidate working condition parameter or initial working condition parameter) corresponding to each parameter type included in the working condition point corresponding to the set of the candidate injection coefficient and the candidate working efficiency parameter, and accordingly, the working condition parameter corresponding to each parameter type included in one working condition point meeting the preset standard can be determined as the optimal working condition parameter corresponding to each parameter type according to each set of the candidate injection coefficient and the candidate working efficiency parameter.
Specifically, each set of candidate injection coefficients and candidate working efficiency parameters may be calculated by a preset algorithm to obtain energy efficiency evaluation values corresponding to each set of candidate injection coefficients and candidate working efficiency parameters, a set of optimal injection coefficients and optimal working efficiency parameters corresponding to the maximum value in the energy efficiency evaluation values may be determined, or a set of candidate injection coefficients and candidate working efficiency parameters corresponding to any one energy efficiency evaluation value greater than the preset value in the energy efficiency evaluation values may be determined as a set of optimal injection coefficients and optimal working efficiency parameters, operating condition points corresponding to the set of optimal injection coefficients and the optimal working efficiency parameters may be determined as optimal operating condition points, and operating condition parameters corresponding to each parameter type included in the optimal operating condition points may be determined as optimal operating condition parameters corresponding to each parameter type.
And 105, regulating and controlling the ejector according to the optimal working condition parameters respectively corresponding to the parameter types.
Specifically, the regulating injector operates according to the optimal working condition parameters corresponding to the parameter types.
It will be appreciated by those skilled in the art that based on the same concept as previously described for determining the optimal operating condition parameters corresponding to the respective parameter types affecting the energy saving performance of the injector, it is also possible to determine the optimal structural parameters of the respective structures affecting the energy saving performance of the injector, so as to design the respective structures of the injector having the better energy saving performance according to the determined optimal structural parameters of the respective structures.
In summary, according to the technical scheme provided by the embodiment of the invention, initial working condition parameters corresponding to the types of parameters affecting the energy saving performance of the injector can be obtained, and the injection coefficient and the working efficiency parameters of the injector are calculated; then determining the influence degree of the parameter type on the injection coefficient and the working efficiency parameter, and determining the target parameter type from the parameter types according to the influence degree respectively corresponding to the parameter types; and then, determining a parameter interval of the initial working condition parameters corresponding to the target parameter types, determining the optimal working condition parameters corresponding to the parameter types respectively according to the parameter interval corresponding to the target parameter types, and regulating and controlling the injector according to the optimal working condition parameters corresponding to the parameter types respectively. In summary, the technical scheme provided by the invention does not directly regulate and control the injector according to the working condition parameters respectively corresponding to the parameter types determined by the working experience of the staff, the accuracy of the obtained optimal working condition parameters respectively corresponding to the parameter types is relatively high, and the energy saving performance of the injector can be improved when the injector is regulated and controlled according to the obtained optimal working condition parameters respectively corresponding to the parameter types.
