Description

Technical Field

[0001] This application relates to the field of installation of dynamic traction cylinders and turbine rotors. More specifically, it particularly relates 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, and has the characteristics of large pumping speed and high compression ratio. It is widely used in fields such as semiconductors, scientific research, and vacuum coating. The traction stage works based on the principle of gas viscosity, and maintains the key index of high compression ratio of the compound molecular pump through the external friction of a moving rigid body on gas molecules.

[0003] For a molecular pump, the dynamic traction cylinder and the turbine rotor need to meet the requirement of the clearance amount. Therefore, before installing the dynamic traction cylinder and the turbine rotor, it is necessary to pair the existing dynamic traction cylinders and turbine rotors. The existing pairing method is to pair the dynamic traction cylinders one by one when installing the turbine rotor. If there is no suitable dynamic traction cylinder for pairing, then wait for the next batch of dynamic traction cylinders. Therefore, the following problems exist: (1) The pairing and installation of the turbine rotor and the dynamic traction cylinder are relatively random. That is, for m dynamic traction cylinders and n turbine rotors, if the maximum number of pairings between the two can be achieved, it can ensure the production progress of the molecular pump.

[0004] (2) The inventory of the turbine rotor and the dynamic traction cylinder increases. Summary of the Invention

[0011] Furthermore, S100 includes the following sub-steps: S101, Obtain the diameter parameter data set Q of the dynamic traction cylinder with any number ii (Q mini , Q maxi ), Q mini 、Q maxi represent the major diameter and minor diameter of the moving traction cylinder numbered i when the roundness is optimal during installation; i is any natural number from 1 to m; Obtain the diameter parameter dataset W of the turbine rotor numbered j j (W minj , W maxj ), W minj 、W maxj represent the major diameter and minor diameter of the turbine rotor numbered j; j is any natural number from 1 to n; S102, Each turbine rotor is paired and tested with m moving traction cylinders, and the pairing parameter set of each turbine rotor is recorded; the pairing parameter set of the turbine rotor numbered j is denoted as (TP j-1 , ……, TP j-xj ).

[0015] An installation method for a turbine rotor and a traction stage, which installs the turbine rotor and the dynamic traction cylinder according to the final paired turbine rotor and dynamic traction cylinder numbers obtained by the foregoing optimized pairing method of the turbine rotor and the traction stage.

[0016] A storage medium, on which a computer program is stored, and when the computer program is executed by a processor, the steps of the foregoing optimized pairing method are implemented.

[0017] The beneficial effects of the present application are as follows: (1) When optimizing the pairing of the turbine rotor and the dynamic traction cylinder, the turbine rotor is used as the judgment criterion. When optimizing the pairing, the following method is required (the optimal number of pairings of the turbine rotor): 1.1, introduce the concept of the pairing parameter set, that is, pre-give the number set of the dynamic traction cylinders that can be paired with each turbine rotor. As Figure 1 shown, the turbine rotor numbered 1 can be paired with the dynamic traction cylinders numbered 1, 5, 7, and 8.

[0018] 1.2, a preliminary pairing result must be given. Directly pairing m dynamic traction cylinders and n turbine rotors cannot directly determine the optimal number of pairings. Because each turbine rotor and each dynamic traction cylinder have many optional pairing methods, it is very difficult to directly analyze all possibilities. The goal of the preliminary pairing result is: 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。

[0019] 1.3, on the basis of the preliminary determination of the pairing results, perform optimized pairing.

[0020] The core solution for optimized pairing lies in: reverse analysis, the first-level reverse analysis to the N-level reverse analysis.

[0021] The process of the above reverse analysis can also be summarized as: "Reverse analysis: Query whether the turbine rotor numbered W b-j can be optimized for pairing; Query whether there is the following replaceable pairing path: turbine rotor numbered W b-j - dynamic traction cylinder numbered TA r - turbine rotor numbered WC1 - dynamic traction cylinder numbered TC2 - turbine rotor numbered WC2 -... - dynamic traction cylinder numbered TC N - turbine rotor numbered WC N - turbine rotor numbered T b-z - dynamic traction cylinder; r is any natural number from 1 to s; TC i is the data in the pairing parameter set of the turbine rotor numbered WC i-1 ; TA r , TC i and WC1, WC i are the numbers of the paired dynamic traction cylinders and turbine rotors; T b-z is any number of the unpaired dynamic traction cylinders, which is in the pairing parameter set of the turbine rotor numbered WC N ; TAr, TC2 to TC N are all different; If there is the above replaceable pairing path, then adjust the pairing relationship: the turbine rotor numbered W b-j is paired with the dynamic traction cylinder numbered TA r , the turbine rotor numbered WC i is paired with the dynamic traction cylinder numbered TC i+1 , the turbine rotor numbered WC N is paired with the dynamic traction cylinder numbered T b-z ; other pairing relationships remain unchanged, and update the data sets of the paired turbine rotor and dynamic traction cylinder numbers and the data set of the unpaired dynamic traction cylinder numbers; i is any natural number from 2 to N; If there is no above replaceable pairing path, it means that: the turbine rotor numbered W b-j cannot be optimized for pairing, replace the next unpaired turbine rotor for reverse analysis".

[0022] (2) Based on Figure 2 , Figure 4 and Figure 7It can be known that: there are only 9 pairs of turbine rotors in the preliminary pairing result; after optimized pairing, all 10 turbine rotors can be paired.

[0023] (3) When the number of turbine rotors and dynamic traction cylinders is small (for example, both the number of turbine rotors and dynamic traction cylinders is 10), a simplified method (limiting triple reverse analysis) can be adopted. Description of the Drawings

S103. Each moving traction cylinder is paired with n turbine rotors for testing, and record the pairing parameter set of each moving traction cylinder; the pairing parameter set of the moving traction cylinder numbered i is denoted as (WP i-1 , ……, WP i-yi ).

[0034] It should be noted that: the requirements for pairing tests can be determined according to actual needs. For example, if both of the following conditions are met: clearance threshold min < Q mini - W maxj and Q maxi - W minj < clearance threshold max , then the turbine rotor numbered j and the moving traction cylinder numbered i can be paired and enter each other's pairing parameter sets.

Logical judgment: If a is greater than xt, then the turbine rotor numbered t cannot be paired, and proceed to step S203; If a is less than or equal to yt, then repeat steps S2022~S2023; Otherwise, the turbine rotor numbered t has no pairing result; S203. Determine whether the pairing test of the n turbine rotors is completed: S2031. Assign t + 1 to t; S2032. If t is less than or equal to n, then repeat steps S202~S203; if t is greater than n, then the initial determination of the pairing result ends, and proceed to step S300.
