Description

Technical Field

[0001] The present application relates to the field of installation of a dynamic traction drum and a turbine rotor, and more specifically, to an optimized pairing method, an installation method, and a storage medium for a turbine rotor and a traction stage. Background Art

[0002] As described in CN103244438A, a compound molecular pump is a high-vacuum pump that combines a turbine stage and a traction stage. It features high pumping speeds and a high compression ratio, making it widely used in fields such as semiconductors, scientific research, and vacuum coating. The traction stage operates based on the principle of gas viscosity, maintaining the compound molecular pump's key high compression ratio through the external friction of a moving rigid body on gas molecules.

[0003] For molecular pumps, the dynamic traction cylinder and turbine rotor must meet clearance requirements. Therefore, before installing the dynamic traction cylinder and turbine rotor, the existing dynamic traction cylinder and turbine rotor need to be matched. The current matching method is to match the dynamic traction cylinders one by one when the turbine rotor is installed. If there is no suitable dynamic traction cylinder to match, the next batch of dynamic traction cylinders must be waited for. This leads to the following problems:

[0004] (1) The pairing of turbine rotors and dynamic traction cylinders is relatively random. That is, for m dynamic traction cylinders and n turbine rotors, if the number of pairs between the two can be maximized, the production progress of the molecular pump can be guaranteed.

[0005] (2) The inventory of turbine rotors and dynamic traction cylinders increased. Summary of the Invention

[0084] A storage medium stores a computer program, which, when executed by a processor, implements the steps of the aforementioned optimized pairing method.

[0085] The beneficial effects of this application are:

[0086] (1) When optimizing the pairing of the turbine rotor and the dynamic traction drum, the turbine rotor is used as the judgment standard. When optimizing the pairing, the following methods are required (the number of turbine rotor pairings is optimal):

[0087] 1.1, the concept of pairing parameter set is introduced, that is, the number set of the pairing dynamic traction cylinders of each turbine rotor is given in advance. Figure 1 As shown, the turbine rotor numbered 1 can be paired with the dynamic traction cylinders numbered 1, 5, 7, and 8.

[0088] 1.2, a preliminary determination of the pairing results must be given. Directly pairing m dynamic traction cylinders and n turbine rotors is not a direct way to determine the optimal number of pairings. Because each turbine rotor and each dynamic traction cylinder has many optional pairing methods, it is very difficult to directly analyze the various possibilities. The goal of the preliminary determination of the pairing results is to determine the unpaired dynamic traction cylinder number dataset and the unpaired turbine rotor number dataset W. 不配对1 ~W 不配对L .

[0089] 1.3. Based on the preliminary pairing results, optimize the pairing.

[0090] The core solution for optimizing pairing lies in reverse analysis, from the first level of reverse analysis to the Nth level of reverse analysis.

[0091] The above reverse analysis process can also be summarized as: "Reverse analysis: query number W b-j Whether the turbine rotors can be optimally paired;

[0092] Check whether the following alternative pairing path exists: number W b-j Turbine rotor - number TA r Dynamic traction cylinder - turbine rotor numbered WC1 - dynamic traction cylinder - turbine rotor numbered TC2 - ... - numbered TC N Dynamic traction cylinder - number WC N Turbine rotor - number T b-z The dynamic traction cylinder; r is any natural number from 1 to s;

[0093] TC i It is numbered WC i-1 Data of paired parameter set of turbine rotor;TA r TC i With WC1, WC i T is the serial number of the paired dynamic traction cylinder and turbine rotor; b-z It is any number of the unmatched dynamic traction cylinder, which is numbered WC N The pairing parameters of the turbine rotor are concentrated; TAr, TC2~TC N All are different;

[0094] If the above replaceable pairing path exists, adjust the pairing relationship: numbered W b-j The turbine rotor is numbered TA r The dynamic traction cylinder pair is numbered WC i The turbine rotor is numbered TC i+1 The dynamic traction cylinder is numbered WC N The turbine rotor is numbered T b-z The paired dynamic traction cylinder is paired, and other pairing relationships remain unchanged. The paired turbine rotor and dynamic traction cylinder number data set and the unpaired dynamic traction cylinder number data set are updated; i is any natural number from 2 to N;

[0095] If the above-mentioned alternative pairing path does not exist, then the number is W b-j The turbine rotor cannot be optimally paired, so replace it with the next unpaired turbine rotor for reverse analysis."

[0096] (2) Based on Figure 2 、 Figure 4 and Figure 7It can be seen that: the initial pairing results show that only 9 turbine rotors are paired; after optimized pairing, all 10 turbine rotors can be paired.

[0097] (3) When the number of turbine rotors and dynamic traction cylinders is small (for example, the number of turbine rotors and dynamic traction cylinders is 10), a simplified method (limited triple inverse analysis) can be used. BRIEF DESCRIPTION OF THE DRAWINGS

[0115] It should be noted that the requirements for pairing test can be determined according to actual needs. For example, if the gap threshold is met at the same time: min < Q mini -W maxj and Q maxi -W minj <Gap Threshold max , then the turbine rotor numbered j and the dynamic traction cylinder numbered i can be paired and enter each other's pairing parameter set. max , gap threshold min Respectively represent the upper and lower limits of the gap threshold.

The pairing parameter set of the turbine rotor numbered 2 is: (3,4), indicating that the turbine rotor numbered 2 can be paired with the dynamic traction cylinders numbered 3 and 4.

[0124] S2021, initialize parameter a to 1;

[0125] S2022, logical reasoning:

[0126] If TP t-a There is an optional dynamic traction cylinder data set KX, then the turbine rotor numbered t and the turbine rotor numbered TP t-a The dynamic traction cylinder is the pairing result; at the same time, update the optional dynamic traction cylinder dataset KX: TP t-a delete;

[0127] If TP t-a If the optional dynamic traction cylinder does not exist in the data set KX, assign a+1 to a;

[0128] S2023, logical reasoning:

[0129] If a is greater than xt, the turbine rotor numbered t cannot be paired, and the process goes to step S203;

[0130] If a is less than or equal to yt, repeat steps S2022 to S2023;

[0135] The method of determining the pairing result in step S202 is essentially: for the turbine rotor numbered t, pair the turbine rotor numbered TP t-1 ~TP t-xt The dynamic traction cylinder is judged in turn, and if it is not selected by other turbine rotors, it is paired with it.

From left to right, the dynamic traction cylinder numbered 6 is paired with the turbine rotor numbered 4 by determining whether they are in KX. This indicates that the optional dynamic traction cylinder data set KX does not pair the dynamic traction cylinder numbered 3 with the turbine rotor numbered 4, resulting in repeated use of the dynamic traction cylinder.

[0155] (10) Pair the turbine rotor numbered 10: its pairing parameter set is 5 and 8. From left to right, determine whether it is in KX. It cannot be paired.

[0156] It should be noted that, when S200 is running, it is not necessary to follow the above method. In fact, if there is an intersection between the paired parameter set of the turbine rotor numbered t and the optional dynamic traction drum data set KX, then any data TP in the intersection is selected. t-h As the pairing result; at the same time, the optional traction cylinder dataset KX will TP t-h Delete; all of the above options are feasible.
