Abstract
The invention discloses an automatic dewatering device for a fuel oil filter. A water accumulation cup and an automatic dewatering device body are sequentially arranged below the fuel oil filter. An exploring electrode and a comparing electrode are arranged inside the water accumulation cup. The exploring electrode comprises a low water level electrode and a high water level electrode. An electromagnetic valve is arranged inside the automatic dewatering device body and located at the position of a dewatering outlet of the water accumulation cup. The exploring electrode, the comparing electrode and the electromagnetic valve are all connected with a control circuit board inside the automatic dewatering device body. The automatic dewatering device is simple in structure; according to the detected water level in the fuel oil filter, accumulated water can be discharged automatically and the dewatering position can be closed automatically; manual operation is needless, an engine and a diesel oil system can be well protected, and losses happening due to the fact that the filter is blocked by water are avoided.
