Description
Technical field:
The utility model relates to field of internal combustion engine, particularly a kind of engine water pump.
Background technique:
The cooling system of available engine, cooling liquid directly enters motor by water pump, common cured formula thermostat only is installed on the water pump to be controlled from the next current of radiator of water tank, and behind the engine start, cooling liquid in the cylinder body water jacket cylinder cap water jacket after heat amount of flowing through is is again scattered and disappeared, make motor just can reach operating temperature for a long time, may make that under the very low situation of external environment the temperature of motor is low excessively, start very difficulty; On the other hand, motor is when cold-starting, because cylinder temperature is lower, cylinder interior divides fuel being difficult to fire burns, fuel is incomplete at in-cylinder combustion, produces a large amount of toxic emissions, if motor is longer in the low-temperature working time, the toxic emission that produces is also more, and country's the 3rd, 4 stage emission regulation demands engine cold are carried out emission test once starting.Directly have influence on the complete machine discharging of motor.Simultaneously, engine temperature will arrive and be raised to the normal working temperature rear engine and just can carry out proper functioning, if engine warms is slower, the energy of internal consumption is also wasted very much during this period of time.
Therefore the temperature-rise period after engine cold state starts is very important, if temperature-rise period is slower, not only influences the cold starting performance of motor, has also increased the weight of the exhaust emission of motor, and has caused energy waste.
Summary of the invention:
Deficiency at above-mentioned prior art existence, the utility model provides a kind of engine water pump, it mainly is made up of belt pulley, water pump body, water pump vane, water pump cover, two-way Jie Lashiwen device, the water intake that on water pump body, is provided with sealing surface, backwater mouth and enters motor, on water pump cover, be provided with water intake, be provided with the warm braw return pipe on the pump housing, structure characteristic is:
Described two-way cured formula thermostat is made up of support, main valve, thermostat shell, spring and auxiliary-valve, in the thermostat shell refined paraffin wax is housed.
The warm-air drier water outlet of described warm braw return pipe and motor links; On the warm braw return pipe, be provided with the warm-air drier switch that control is opened.
The utility model improves the linkage structure of available engine water pump and cooling system, effectively improve cold machine and started the slower shortcoming of rear engine intensification, adopt a simple structure of cover and a control structure, making engine cold start rear engine heats up rapidly, when improving the engine cold-start performance, reduce the motor pollution on the environment, energy saving.

Fig. 2 is the right side view of Fig. 1.
Fig. 3 is the structure diagram of two-way thermostat.
Installation when Fig. 4 is pump working connects schematic diagram.
Fig. 5 is a cold machine engine water circular chart when starting.
Water cycle figure when Fig. 6 is the motor proper functioning.
Fig. 7 is operator cabin water cycle figure when needing warm braw.
Embodiment reaches embodiment in conjunction with the accompanying drawings and describes.
As Fig. 1, shown in 2, the engine water pump that the utility model proposes mainly is made up of belt pulley 1, water pump body 2, water pump vane 3, water pump cover 4, two-way Jie Lashiwen device 5, the water intake 9 that on water pump body, is provided with sealing surface 7, backwater mouth 8 and enters motor, on water pump cover, be provided with water intake 6, on the pump housing, be provided with warm braw return pipe 10.
As Fig. 3, two-way cured formula thermostat 5 mainly is made up of support 15, main valve 14, thermostat shell 13, spring 12 and auxiliary-valve 11, in the thermostat shell 13 refined paraffin wax is housed.During normal temperature, it is solid-state that paraffin wax is, and spring 12 is pushed main valve 14 direction of pump intake 6 to, close water intake 6, and auxiliary-valve 11 leaves sealing surface 11, opens backwater mouth 8.When the engine water temperature rise, paraffin is liquefy gradually, its volumetric expansion, overcome spring 12 pretightening forces promotion thermostat shell and move to sealing surface 7, main valve 14 is opened, and water intake 6 is opened, simultaneously, auxiliary-valve moves to sealing surface 7 gradually, and backwater mouth 8 is closed gradually, when temperature reaches 80～85 ℃.Main valve 14 standard-sized sheets, auxiliary-valve 11 Close Alls.
Shown in Figure 4 is that water pump connects figure with the motor water route.Water intake 6 on the engine water pump links with the water outlet of radiator of water tank 16, backwater mouth 8 links with the water intake of radiator of water tank 16, warm braw return pipe 10 links with the water outlet of warm-air drier 17, and water intake 9 links with the cylinder cap and the body water jacket 18 of motor.
As Fig. 5, when motor during at cold machine state, the paraffin waxes in the thermostat shell 13 are solid-state, the direction of pump intake 6 pushed main valve 14 to by spring 12, close water intake 6, and backwater mouth 8 is opened, the cooling liquid in the engine water jacket 18 can enter water pump from backwater mouth 8.When engine start, because water intake 6 is closed, can not enter water pump from the cooling liquid of radiator 16, and the cooling liquids in the engine water jacket 18 have only cooling liquid in the cylinder cap to do to enter engine water jacket 18 again by pump intake 9 in the suction of water pump to carry out inner loop.The heat that the engine cylinder-body internal combustion produces passes to cooling liquid in cylinder cap and the cylinder body by water jacket, and the cooling liquid in engine cylinder-body, the cylinder cap can be heated rapidly, reaches operating temperature fast.
As Fig. 6, when engine temperature raises gradually, paraffin in the thermostat shell 13 is liquefy gradually, its volumetric expansion, overcoming spring 12 pretightening forces promotion thermostat shell moves to sealing surface 7, two-way cured formula thermostat is opened, water intake 6 is opened, cooling liquid in the radiator of water tank 16 is drawn into motor by water pump and participates in the circulation cooled engine, valve 11 moves to sealing surface 7 simultaneously, close backwater mouth 8 gradually, after motor enters proper functioning (80～85 ℃), when thermostat reaches maximum position, valve 11 is fitted with sealing surface 7, backwater mouth 8 is closed, and the cooling liquid of coming in from radiator is all got back to the radiator of water tank cooling after by motor, and cooling liquid can be cooled off motor fully.
As Fig. 7, when operator cabin needs warm braw, open warm-air drier switch 19, warm water enters 17 pairs of operator cabin heating of warm-air drier from motor, gets back to return pipe 10 then and enters water pump again, participates in the circulation of engine coolant.
