Embodiment
It should be noted that, in the situation that not conflicting, the feature in embodiment and embodiment in the present invention can combine mutually.Technological scheme of the present invention is described below with reference to the accompanying drawings and in conjunction with the embodiments.
Basic thought of the present invention is: the filter cleaner that engine coolant is filtered is arranged on water pump, facilitates cooling liquid is filtered, 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: as shown in Figures 1 to 5, 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 being installed on 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 filtering in entering filter cleaner 5 by filtering inlet channel 7 under the pressure-acting that part cooling liquid in water chamber 4 produces in impeller 1 rotation, enter water-inlet cavity 4 by filtering backwater road 6.
Water pump is the power of cooling liquid in engine interior circulation, and the impeller 2 of cooling liquid in water chamber 4 rotates the circulation of realization in motor under the active force producing.Therefore filter cleaner 5 is installed on water pump, can be ensured the cooling liquid in water pump to filter, 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, in figure, arrow represents the flow direction of cooling liquid, the water inlet of filter cleaner 5 is communicated with the water chamber 4 of water pump by filter cleaner inlet channel 7, the water outlet of filter cleaner 5 is communicated with the water-inlet cavity 3 of water pump by filter cleaner backwater road 6, part cooling liquid in water chamber 4 is rotated under the pressure-acting producing and is entered filter cleaner 5 by filtering inlet channel 7 at impeller 1, after filtering, enter water-inlet cavity 4 by filtering backwater road 7 again, cooling liquid in water-inlet cavity 4 returns backwater cavity 3, cooling liquid part in backwater cavity 3 enters and in engine water jacket, carries out cool cycles, another part enters in filter cleaner 5 and filters, so circulation.
Filtering backwater road 6 and filtering inlet channel 7 can set up in water pump periphery pipeline and form.
In one, preferably in mode of execution, as shown in Figure 4, filtering inlet channel 7 is one section of cooling passage with a bend 8 being processed to form on pump case 2 housings; As shown in Figure 5, filtering backwater road 6 is one section of cooling passage being processed to form on pump case 2 housings under the bend 8 being positioned on filtering inlet channel 7.By process cooling passage on pump case 2 housings, 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, on filtering inlet channel 7 and filtering backwater road 6, be provided with the first check valve 9, for opening or closing filtering inlet channel 7 and backwater road 6, be convenient to maintenance and maintenance.While changing filter cleaner 5, first close the first check valve 9, then pull down filter cleaner 5 and change, the outflow of a large amount of cooling liquids while preventing from changing filter cleaner 5, the waste that cost is caused, environmental pollution.The first check valve 9 can be set to two, controls respectively filtering inlet channel 7 and filtering backwater road 6.
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 being nested in pump case 2 housings simultaneously, and this second check valve 10 is successively through bend 8, filtering backwater road 6 on pump case 2, filtering inlet channel 7; Fig. 7 is the structural drawing of the second check valve 10, and the second check valve 10 is provided with through the position of bend 8 the first through hole 11 adapting with bend 8, is provided with through the position in filtering backwater road 6 the second through hole 12 adapting with filtering backwater road 6.In the time that the second check valve 10 is positioned at enable possition, the first through hole 11 is connected with bend 8, and the second through hole 12 is connected with filtering backwater road 6, and filtering inlet channel 7 and filtering backwater road 6 are opened; In the time of the second check valve 10 axial-rotation several angle, the first through hole 11 staggers with bend 8, and the second through hole 12 staggers with filtering backwater road 6, and the second check valve 10 is positioned at closed condition, and filtering inlet channel 7 and filtering backwater road 6 are closed.
So only second check valve 10 need to 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 the second check valve 10 arranges groove, and the mark of the opening and closing position of the second check valve 10 is set in the relevant position of pump case 2, opens as " 1 " representative, and " 0 " representative is closed; When groove is facing to mark " 1 ", the second check valve 10 is opened, and when groove is facing to mark " 0 ", the second check valve 10 is closed, convenient operation like this.
As shown in Figure 7, the top of the second check valve 10 is provided with grooved ring 13, and pump case 2 is provided with the corresponding position of grooved ring 13 positioning device 14 of fixing the second check valve 10 positions.Positioning device 14 can be locating stud or holding down bolt.In the time need to converting the state position of the second check valve 10, first unscrew positioning device 14, the second check valve 10 is rotated to and opened or closed position, then positioning device is tightened, like this, can prevent that the second check valve 10 from axially or radially moving.
In order to improve sealing, on the second check valve 10, can also be provided with the O type circle of seal action.
In sum, the engine water pump tool that the embodiment of the present invention provides has the following advantages:
On water pump, install filter cleaner, can ensure the cooling liquid in water pump to filter, can arrange easily cooling passage, can save the peripheral space of motor;
On pump case housing, be processed to form cooling passage, sealing, without additional pipe, has been improved in water pump outside, has saved space;
Pain relieving valve is set on cooling passage, is convenient for changing filter cleaner.
