The utility model content
The purpose of this utility model is, overcome the defective of above-mentioned prior art and a kind of total system flow that can improve is provided, and guarantee the Vehicular electric water pump that the vehicle driver can keep in repair vehicle home, James or maintenance station and the unitized construction of dynamoelectric water valve when vehicle electric water valve or electric water pump lost efficacy.
For achieving the above object, the utility model is taked following design plan:
The unitized construction of a kind of Vehicular electric water pump of the present utility model and dynamoelectric water valve, comprise at least the first dynamoelectric water valve, second dynamoelectric water valve and at least the first electric water pump, second electric water pump, described first dynamoelectric water valve is connected mutually with first electric water pump, described second dynamoelectric water valve and second electric water pump are connected mutually, and between the two ends of described first dynamoelectric water valve, second dynamoelectric water valve and parallel with one another by at least one communicating pipe between the two ends of described first electric water pump, second electric water pump.
Preferably, need the part of cooling or heating to link to each other on described first electric water pump and the vehicle.
Preferably, described second electric water pump links to each other with another part that need cool off or heat on the vehicle.
Preferably, described unitized construction also comprises the Failure Alarm system, described first dynamoelectric water valve, second dynamoelectric water valve, first electric water pump, and second electric water pump all links to each other with described Failure Alarm system.
The utility model has the advantages that: the utility model is by at least two cover electric water pumps in parallel and the unitized construction of dynamoelectric water valve, can improve the flow of total system, and at the electric water pump of vehicle or dynamoelectric water valve et out of order and when losing efficacy, guarantee that chaufeur can or reach maintenance station and keep in repair the vehicle home, James.
