What is the effect of air leakage from the water drain valve of freight car air cylinder?

Air leakage from the auxiliary air storage tank will cause these failures.

① Insufficient air pressure in the auxiliary air cylinder causes the clutch booster pump not to work normally and the clutch does not separate, which is the most direct fault. After a long stop, starting the engine will consume a lot of fuel to supplement the air pressure.

② The shift cylinder of the transmission can't work normally, resulting in serious transmission failure.

③ The exhaust butterfly valve or air horn does not work.

● What is the reason for the air leakage of the auxiliary air storage tank?

① The components prone to frequent air leakage are firstly air horns, with thin pipes and large length span; In particular, dump trucks are prone to long-term violent bumps and air leakage.

(2) Various air solenoid valves. This kind of air leakage is often not serious and needs careful investigation.
