<Processing procedure of the seal construction training>

21 has shown the processing procedure of the seal construction training. This processing procedure is an example of a seal construction training program or a seal construction training method.

In the processing procedure of the seal construction training, it is determined whether or not it is training as a confirmation of the intention to the trainee from the training screen of the PC (S401). When transitioning to training (YES in S401), it is checked whether the importance of selecting a seal material has been recognized (S402). If the importance of selecting a seal material is not recognized (NO in S402), the number of years for selecting a seal material is imposed (S403). The training for this selection of seal materials can be carried out by re-learning the sit-school. In this way, the intention of the recognition confirmation of the selection of the seal material is to recognize the seal material used in the actual seal construction, to train the seal construction on the premise of the recognition, and to increase the training effect. When the training (S403) of selection of a sealing material is finished, the process returns to S402.

If the importance of selecting a seal material is recognized (YES in S402), the skill of the trainee is determined (S404). This skill determination is performed according to the processing procedure of skill determination (FIG. 22).

After skill determination, training course is selected (S405). This course selection is performed in accordance with the course selection process (Fig. 23).

After selecting a course, the intention of training is confirmed (S406), and training of the sit-study program is first performed by starting the training (YES in S406) (S407). This sitting study program is implemented by the sitting study system 34-1, and ends at a predetermined subject and time. In that case, re-learning is required depending on the evaluation.

When this sitting study program is ended (YES in S408), the process proceeds to the training program S409. This training program is implemented by the training system 34-2, equipment is selected according to a predetermined subject and time, and necessary training is performed. In that case, evaluation is performed based on sensor output and input information based on training, and relearning is required depending on the evaluation.

When this training program is ended (YES in S410), the training program for seal construction is ended, and a completion indication is presented (S411).

<Processing procedure of skill judgment>

22 shows the procedure of skill determination. When the process shifts to the procedure of skill determination, it is determined whether it is a rookie or a general person (S501). This processing may be performed based on the trainee's input information. “Rookie” is a person who is in charge of seal construction, but has the same experience as the managing director or managing director. “General” means a general public who wants to be enlightened in the future, such as students.

If it is a rookie or a general person (YES in S501), skill 1 is selected (S502), and the process returns to S404 in the seal construction training program (FIG. 21).

If it is not a rookie or a general person (NO in S501), the process proceeds to inputting skill information (S503). As skill information input, information necessary for skill determination is input, and skill determination is performed based on this information input (S504). By this skill determination, from a plurality of skills, skill 2, skill 3, ... It is allocated to any of skill N (S505). In this example, the trainee is divided into N stages from the lowest skill 1 to the highest skill N, and returns to S404 of the seal construction training program (FIG. 21). This skill level can be any of the 2nd level, 3rd level, 4th level, 5th level, etc.

<Process of course judgment>

23 shows the procedure of course selection. When shifting to the course selection processing sequence, it is determined whether it is a new person or a general person (S601). As already described, this process may be performed based on the trainee's input information.

If it is a rookie or a general person (YES in S601), the basic course is selected (S602), and the process returns to S405 in the seal construction training program (FIG. 21).

If it is not a rookie or a general person (NO in S601), it is determined whether it is a custom course (S603). If it is not a custom course (NO in S603), the trainee's job type is determined (S604). Based on the job type determination, from multiple advanced courses, advanced course 1, advanced course 2… Any of the advanced courses N is selected (S605).

If it is a custom course (YES in S603), the trainee's job type is determined (S606). Based on the job type determination, custom course 1, custom course 2… from multiple custom courses. Any of the custom courses N is selected (S607).

At the site of sealing construction, as shown in A of FIG. 29, when the distance between each flange 226 of the pipes 240-11 and 240-12 to be connected is wide, as shown in B of FIG. 29, the pipe When the distance between the flanges 226 of (240-11, 240-12) is narrow, as shown in C of FIG. 29, the inclination between the flanges 226 of the pipes (240-11, 240-12) Because there is, when parallelism is not obtained, as shown in D of FIG. 29, when there is a seam shift between the flanges 226 of the pipes 240-11 and 240-12, it encounters. In such a situation, even if tightened with a uniform clamping force, an appropriate clamping force cannot be transmitted to the gasket 228. In this piping alignment training apparatus 80-5, the actual misalignment is reproduced by freely setting gaps, inclinations, and seam misalignment, and the trainees practice sealing construction to resolve the misalignment. For these situations, the situation of tightening (surface pressure) by the trainee is evaluated.

Example 6

The structure of the heat exchanger is more complicated than that of a general pipe connection flange, and the seal construction is required to be performed from understanding the structure. In the fixed pipe plate, since two gaskets are sandwiched between flanges and tightened, tightening bias is likely to occur. In a large-diameter flange, the number of bolts is large, and the decrease in tightening force between adjacent bolts during tightening due to elastic interaction between the flanges cannot be ignored. In addition, with respect to the partition plate, when a seam shift occurs in the tube flange/shell flange, a problem such as the partition plate does not enter the groove and sits up occurs. Such a special structure, optimum clamping force, selection of an appropriate construction tool, and tightening sequence are required.

In this heat exchanger training apparatus, the heat exchanger is disassembled, and the trainee is trained to practice tightening the bolts of the fixed pipe plate and shim fitting of the tube flange and shell flange necessary for sealing construction.

Example 7

In the compression fracture training apparatus, the trainee learns about compression fracture of the gasket due to excessive tightening or the like. Compression fracture reproduces a situation in which compression fracture is likely to occur for the type of gasket, paste application, small diameter flange, and the like, and learns the cause of leakage and its prevention. For example, the expanded graphite sheet gasket has a lower compression fracture surface pressure than other gaskets, improves sealing properties when applied with a paste, but is prone to compression fracture, and has a small gasket area for the number of bolts in a small diameter flange. , The surface pressure is liable to be high, and thus compression fracture is liable to occur.

Therefore, in this compression fracture training apparatus, the type of gasket, the presence or absence of a paste, and the relationship between crack deformation and cracking, which are factors of compression fracture, can be learned from the trainee for compression fracture as a cause of leakage.

Example 8

As other embodiments, a torque sensory training device, a ground packing training device for a practical machine rotary pump, and a ground packing training device for a practical machine valve are used. In the torque sensory training apparatus, it is possible to make the trainee sense the change of tightening torque and axial force for a plurality of bolts and nuts having different tightening conditions.
