Example 2
Referring to fig. 1, for better explaining the working process of the present system, assuming that the shield has 4 shield tail brushes 150 and 16 injection holes, the shield has 3 grease injection cavities: the anterior chamber F, the middle chamber M and the tail chamber R have 48 grease injection holes 1311F 1-F16, M1-M16 and R1-R16.
The specific working process is as follows: firstly, an operator selects an automatic mode control on an operation interface of the control mechanism; then selecting an extraction component to be started, clicking automatic grease injection setting, and setting the priority injection sequence of 3 grease injection cavities and 16 grease injection holes 1311 by an operator according to the actual situation on site; and returning to the operation interface, setting injection interval time, cycle stop time, injection pressure and pressure upper limit value, clicking grease injection detailed data, setting injection time of 48 grease injection holes 1311, and clicking and starting on a control panel after the setting of the parameters is finished, so that grease injection can be performed.
Under normal conditions, the defaults are single work, namely, the circulation is repeated according to the front-back sequence of the grease filling cavities and the set sequence of the grease filling holes 1311. The specific process is as follows: injecting a first grease injection hole 1311 of a selected F cavity for a set injection time of the grease injection hole 1311, stopping injecting the grease injection hole 1311 when the time is up, injecting a second grease injection hole 1311 of the selected F cavity for a set injection time of the grease injection hole 1311, stopping injecting the grease injection hole 1311 and injecting the next grease injection hole 1311 when the time is up, and so on, injecting the grease injection hole 1311 selected by the M cavity and finally injecting the grease injection hole 1311 selected by the R cavity, stopping the set cycle stop time when the selected grease injection hole 1311 of the R cavity is completely injected, and then circulating the operations.
When the user selects linkage, the three grease injection cavities are synchronously injected according to the set sequence of the selected grease injection holes 1311 and are circularly reciprocated. The specific process is as follows: injecting the selected first F cavity grease injection hole 1311, the first M cavity grease injection hole 1311 and the first R cavity grease injection hole 1311 for the set injection time of the grease injection hole 1311, injecting the selected second F cavity grease injection hole 1311, the second M cavity grease injection hole 1311 and the second R cavity grease injection hole 1311 after the time is up, and so on, stopping the set cycle stop time after the cycle is completed, and then circulating the operation. Because the number of the grease injection holes 1311 selected by each grease injection cavity and the injection time may be different during linkage, the completion time of each grease injection cavity is different, the control mechanism defaults to preferentially complete the circulation of the injected grease injection cavity and stops the circulation, and after all the grease injection cavities complete the action, the circulation of the next period is performed.
