Mechanical seal

Why is the remote transmission of the primary stage leakage pressure of the compressor sometimes an auxiliary value? Thank you!
Are you referring to the leakage amount of the main seal? Initially, there was already leakage from the main seal, and that initial leakage amount serves as a baseline. The leakage amount under operating conditions is calculated by subtracting the initial leakage amount from the actual leakage amount; therefore, when it’s less than the initial leakage amount, a negative value may occur, based on my personal understanding
