Abstract
The invention provides a cooling water pump for an engine. The cooling water pump for the engine comprises a volute. A water inlet and a water outlet are formed in the volute. The volute is further provided with a water return port. An independent communicating pipeline is arranged between the water return port and the water inlet. By the adoption of the technical scheme, due to the fact that a small-circulation water return pipeline is directly integrated to the volute, when the engine is in a preheating stage, the cooling water pump carries out small cooling circulation, cooling liquid passes through a thermostat and then directly flows into the water inlet through the water return port in the volute, connection of a water pump inlet with another connecting pipeline on the thermostat is not needed, the operation distance and resistance of the small cooling circulation are reduced, and insignificant power consumption of the engine in the preheating stage is reduced.
Description
Technical field
The present invention relates to a kind of cooling waterpump of motor.
Background technique
The operating temperature that motor is general is 85 ~ 95 DEG C, needs time preheating after motor just starts, and water pump can only run with motor by driving mode restriction.Therefore at warm-up phase, require that cooling liquid is without radiator, but directly get back to unit fixed on water pump suction by thermostat, this circulation is cooling short circle (see Fig. 1).There is not actual cooling meaning in the operation due to this stage water pump, therefore needs the resistance reducing this short circle as far as possible, reduces the insignificant power consumption of motor.
Summary of the invention
The technical problem to be solved in the present invention is to provide a kind of engine cooling water pump that can reduce motor partial circulation operation Distance geometry resistance.
For solving the problems of the technologies described above, technological scheme of the present invention is: a kind of engine cooling water pump, comprises volute, and described volute is provided with water intake and water outlet, described volute is also provided with backwater mouth, between described backwater mouth and water intake, is provided with independently connecting pipeline.
Preferably, described backwater mouth is positioned at the outside of described water outlet.
Preferably, the end face of described backwater mouth is mutually concordant with the end face of described water outlet.
Preferably, the bore size of described backwater mouth is less than the bore size of described water outlet.
In technique scheme, due to the water return pipeline of short circle is directly integrated on volute, like this when motor is at warm-up phase, cooling waterpump carries out cooling short circle, cooling liquid directly flows into water intake by the backwater mouth on volute after thermostat, without the need to being connected with unit fixed on water pump suction by other connecting pipeline on thermostat, decreasing range ability and the resistance of cooling short circle, reducing the meaningless power consumption in engine warming up stage.

Fig. 1 is engine-cooling system circulation schematic diagram;
Fig. 2 is turbocharger housing structure schematic diagram of the present invention;
Fig. 3 is that the A of Fig. 2 is to structural representation;
Fig. 4 is the section B-B structural representation of Fig. 2;
Reference character is:
1---volute 11---water intake 12---water outlet 13---backwater mouth.
Embodiment
As shown in Figure 2,3, 4, the preferred embodiments of the present invention are: a kind of engine cooling water pump, comprise volute 1, described volute is provided with water intake 11 and water outlet 12, described volute is also provided with backwater mouth 13, independently connecting pipeline is provided with between described backwater mouth 13 and water intake 11, described backwater mouth 13 is positioned at the outside of described water outlet 12, the end face of described backwater mouth 13 is mutually concordant with the end face of described water outlet 12, and the bore size of described backwater mouth 13 is less than the bore size of described water outlet 12.
As shown in Figure 1, due to the water return pipeline of short circle is directly integrated on volute 1, like this when motor is at warm-up phase, cooling waterpump carries out cooling short circle, cooling liquid directly flows into water intake 11 by the backwater mouth 13 on volute 1 after thermostat, without the need to being connected with unit fixed on water pump suction by other connecting pipeline on thermostat, decreasing range ability and the resistance of cooling short circle, reducing the meaningless power consumption in engine warming up stage.
Above-described embodiment is the present invention's preferably implementation, and in addition, the present invention can also realize by alternate manner, and under the prerequisite not departing from the technical program design, any apparent replacement is all within protection scope of the present invention.
The improvements of the present invention relative to prior art are understood more easily in order to allow those of ordinary skill in the art, accompanying drawings more of the present invention and description are simplified, and for the sake of clarity, present specification is omitted some other elements, and those of ordinary skill in the art it is to be appreciated that these abridged elements also can form content of the present invention.
