The existing scheme has the following defects:
1. personnel are required to watch in the whole process, and manpower is wasted. The on-site debugging personnel are short, and the expansion tank liquid feeding needs special arrangement personnel to observe the inside coolant liquid filling condition of expansion tank. When the expansion water tank reaches a certain liquid level, another person is arranged to close the water pump in time, so that the overflow of the cooling liquid is prevented.
2. The time consuming is a long problem. The project period is limited, the expansion water tanks are required to be filled for the first time in batch machine set installation, each expansion water tank needs at least 2-3 hours, the efficiency is low, and the project progress is seriously affected.
