Summary of the invention
Technical problem to be solved in the utility model be to provide a kind of can realize quick fuel feeding, again can the cool electronic control unit or the device of electronic control module.
The technological scheme that the utility model adopted is: a kind of electrically operated fuel pump system that has cooling unit, be used for one and have the diesel engine of high-pressure common-rail injection system, this electrically operated fuel pump system comprises the oiler of the extraneous fuel oil input of cooling plate, electrically operated fuel pump, reception and fuel oil is outputed to the oil outlet of high-pressure common-rail injection system that cooling plate is provided with cooling oil duct; Wherein, in an end of this cooling oil duct and the import of electrically operated fuel pump, in the outlet of the other end and the electrically operated fuel pump of this cooling oil duct, oiler is provided with an one-way valve to oil outlet to oiler by second pipeline connection by first pipeline connection.
After adopting technique scheme, the utility model can obtain following beneficial effect:
1. the utility model is integrated with the cooling unit of electrically operated fuel pump, engine electronic control unit or electronic control module etc., has realized that low pressure oil circuit fuel oil is supplied with fast and the function of cooled engine electronic control unit or electronic control module.
2. the utility model has adopted the one-way valve that has rapid pipe joint at cooling plate oiler place, effectively prevented this system inner loop when quick fuel feeding, improve fuel flow and the predetermined oil pressure of diesel engine under the low cruise situation, guaranteed the smooth starting under the diesel engine low cruise situation.
3. be provided with the fuel oil circulation loop on the cooling plate of the present utility model, this loop both can realize engine electronic control unit or electronic control module are cooled off, and can realize that fuel oil normally circulates when electrically operated fuel pump quits work again.
