Embodiment
Need to prove that under the situation of not conflicting, embodiment and the characteristic among the embodiment among the present invention can make up each other.Below with reference to accompanying drawing and combine embodiment that technological scheme of the present invention is described.
Basic thought of the present invention is: will be installed in the filter cleaner that engine coolant filters on the water pump, and promptly make things convenient for cooling liquid is filtered, and have and be convenient to arrange filtration water channel, the arrangement space of saving motor.
Below in conjunction with accompanying drawing; Each preferred embodiment of the present invention is described further: extremely shown in Figure 5 like Fig. 1; The invention provides a kind of engine water pump; Comprise impeller 1, pump case 2, water-inlet cavity 3, water chamber 4; Wherein also comprise the filter cleaner 5 that is installed on the pump case 2, be communicated with the filtering backwater road 6 of filter cleaner 5 and water-inlet cavity 3 and be communicated with the filtering inlet channel 7 of filter cleaner 5 and water chamber 4, after the part cooling liquid in the water chamber 4 is filtered in impeller 1 rotates under the pressure effect that produces through filtering inlet channel 7 entering filter cleaners 5, through filtering backwater road 6 entering water-inlet cavitys 4.
Water pump be cooling liquid at engine interior circuit power, the impeller 2 of cooling liquid in water chamber 4 rotates under the active force that produces and is implemented in the circulation in the motor.Therefore filter cleaner 5 is installed on water pump, can be guaranteed the cooling liquid in the water pump is filtered, and can arrange easily that filtering inlet channel 7 and filtering backwater road 6 saved the peripheral space of motor.The cooling liquid work principle of filter figure of Fig. 6 one embodiment of the present of invention; Arrow is represented the flow direction of cooling liquid among the figure; The water inlet of filter cleaner 5 is communicated with the water chamber 4 of water pump through filter cleaner inlet channel 7, and the water outlet of filter cleaner 5 is communicated with the water-inlet cavity 3 of water pump through filter cleaner backwater road 6, and the part cooling liquid in the water chamber 4 is rotated under the pressure effect that produces at impeller 1 and got into filter cleaner 5 through filtering inlet channel 7; After filtering; Get into water-inlet cavity 4 through filtering backwater road 7 again, the cooling liquid in the water-inlet cavity 4 returns backwater cavity 3, and the cooling liquid part in the backwater cavity 3 gets in the engine water jacket and carries out cool cycles; Another part gets in the filter cleaner 5 and filters, so circulation.
Filtering backwater road 6 can set up pipeline in the water pump periphery with filtering inlet channel 7 and form.
In a kind of preferably mode of execution, as shown in Figure 4, filtering inlet channel 7 is one section cooling passage with a bend 8 that on pump case 2 housings, is processed to form; As shown in Figure 5, filtering backwater road 6 be one section at the cooling passage that is processed to form on pump case 2 housings under the bend 8 that is positioned on the filtering inlet channel 7.Through on pump case 2 housings, processing cooling passage, can increase sealing reliability, reduce extra pipe fitting cost, beautify outward appearance.
Because filter cleaner 5 needs to change in use for some time; In another embodiment, as shown in Figure 6, filtering inlet channel 7 is provided with first check valve 9 with filtering backwater road 6; Be used for opening or closing filtering inlet channel 7 and backwater road 6, be convenient to maintenance and maintenance.When changing filter cleaner 5, close first check valve 9 earlier, pull down filter cleaner 5 again and change, the outflow of a large amount of cooling liquids when preventing to change filter cleaner 5, waste, environmental pollution that cost is caused.First check valve 9 can be set to two, controls filtering inlet channel 7 and filtering backwater road 6 respectively.
In another preferred implementation; As shown in Figure 4; The open and close in filtering inlet channel 7 and filtering backwater road 6 are controlled by tubular second check valve 10 that is nested in pump case 2 housings simultaneously, and this second check valve 10 passes bend 8, the filtering backwater road 6 on pump case 2, the filtering inlet channel 7 successively; Fig. 7 is the structural drawing of second check valve 10, and the position that second check valve 10 passes bend 8 is provided with first through hole 11 that adapts with bend 8, and the position of passing filtering backwater road 6 is provided with second through hole 12 that adapts with filtering backwater road 6.When second check valve 10 was positioned at the enable possition, first through hole 11 was connected with bend 8, and second through hole 12 is connected with filtering backwater road 6, and filtering inlet channel 7 is opened with filtering backwater road 6; When second check valve 10 axially rotated to an angle, first through hole 11 staggered with bend 8, and second through hole 12 staggers with filtering backwater road 6, and second check valve 10 is positioned at closed condition, and filtering inlet channel 7 is closed with filtering backwater road 6.
So only one second check valve 10 need be set, just can realize the control that filtering inlet channel 7 and filtering backwater road 6 open and close simultaneously, the flow process that simplifies the operation has increased the sealing reliability of water pump, is beneficial to processing, reduces cost.
In a kind of embodiment, as shown in Figure 3, the top of second check valve 10 is provided with groove, and the sign of the opening and closing position of second check valve 10 is set in the relevant position of pump case 2, opens like " 1 " representative, and " 0 " representative is closed; Identify " 1 " when groove faces toward, second check valve 10 is opened, and identifies " 0 " when groove faces toward, and second check valve 10 is closed, and is convenient to like this operate.
As shown in Figure 7, the top of second check valve 10 is provided with grooved ring 13, and pump case 2 is provided with the positioning device 14 of fixing second check valve, 10 positions with grooved ring 13 corresponding positions.Positioning device 14 can be locating stud or holding down bolt.When needing the state position of conversion second check valve 10, unscrew positioning device 14 earlier, second check valve 10 is rotated to open or closed position, again positioning device is tightened, like this, can prevent that second check valve 10 from axially or radially moving.
In order to improve sealing, can also be provided with the O type circle of seal action on second check valve 10.
In sum, the engine water pump that provides of the embodiment of the invention has following advantage:
Install filter cleaner on the water pump, can guarantee the cooling liquid in the water pump is filtered, can arrange cooling passage easily, can save the peripheral space of motor;
On the pump case housing, be processed to form cooling passage, the outside no additional pipe of water pump has improved sealing, has practiced thrift the space;
The pain relieving valve is set on cooling passage, is convenient for changing filter cleaner.
