Sample distributions under four different conditions.

Datasets	Load (MPa)	Number of training samples/testing samples	Fault type	Label
A	1	100/50	No internal leakage	1
		100/50	Small internal leakage	2
		100/50	Medium internal leakage	3
		100/50	Large internal leakage	4
B	2	100/50	No internal leakage	1
		100/50	Small internal leakage	2
		100/50	Medium internal leakage	3
		100/50	Large internal leakage	4
