Description
Technical Field
The invention relates to the technical field of running and overhauling tools of hydroelectric generating sets, in particular to a system and a method for adjusting air outlet based on air supply capacity of a compressed air system.
Background
The air compressor of the existing compressed air system is mainly controlled according to the fixed value of the starting and stopping pressure, when the system pressure is reduced to the fixed value of the starting pressure of the starting air compressor, the air compressor is started to operate, and the operation is stopped until the system pressure is increased to the fixed value of the stopping air compressor or the air compressor fails, so that the air consumption of a user end does not participate in any control. When a great amount of air is used by the user end, the air compressor can continuously run for a long time because the air supply pipeline is not provided with a device for automatically adjusting the air consumption. The air compressor is overheated or overloaded and other faults can be caused by the fact that the two starting time intervals of the air compressor are too short or continuous running for a long time, and the service life of the air compressor is influenced; the system pressure may also drop to unacceptable values due to the continued greater gas usage than gas supply capacity. In order to avoid the above situation, a group of people is often required to monitor the operation condition of the compressed gas system when a great amount of gas is used at the user side, and the manual intervention is required, so that time and labor are wasted and manpower resources are wasted.
