(1) Če je konektor magnetnega ventila ohlapen ali odpade, magnetni ventil pa ni vklopljen, lahko priključek privije .
(2) Tuljava magnetne ventila je izgorela . Magnetno žico lahko odstranite in izmerite z multimetrom . Če je vezje odprto, bo malenoidna tuljava izgorela .
The reasons include damp coil, poor insulation and magnetic flux leakage, resulting in excessive coil current and burn out. The solenoid valve is expensive, so it is necessary to prevent rainwater from entering the solenoid valve. In addition, if the spring is too hard, the reaction force is too large, the number of turns of the coil is too small, and the suction force is not enough, the coil will burn Out .
