Direction forms dome arch.
Preferably, the circlip is equipped with draw ring arrangement far from the position of tapered thread mouth, and the draw ring arrangement is set
On the planar annular of the circlip, it is equipped with through-hole among it.
Preferably, the water pump cover is equipped with several reinforcing ribs, improves the intensity of water pump cover, extends it and uses the longevity
Life.
Compared with prior art, the utility model provides a kind of engine centrifugal water with intake tunnel strainer
Pump, have it is following the utility model has the advantages that
1. add filter device at the close impeller portion of water inlet, to ensure to will be free from the water entered in pump
Grain object impurity, then and not change the shape of water pump, and can improve the safety in utilization of water pump, it is ensured that will not be to the normal fortune of water pump
Turn to impact, to effectively play a certain protective role other equipment；
2. net-filter assembly can be taken out in the case where not destroying the strainer due to the setting of draw ring arrangement,
Easy to disassemble, cleaning net-filter assembly, to realize reuse.
Detailed description of the invention
Fig. 1 is a kind of structural representation of the engine centrifugal water pump with intake tunnel strainer provided by the utility model
Figure；
Fig. 2 is the cross-sectional view in Fig. 1 at tapered thread mouth；
Fig. 3 is the structural schematic diagram of the net-filter assembly in embodiment.
Wherein: 1- water inlet, 2- water outlet, 3- impeller portion, 4- tapered thread mouth, 5- taper screw plug, 6- annular slot, 7-
Net-filter assembly, 71- circlip, 72- strainer, 73- dome arch, 74- draw ring arrangement, 75- through-hole.
Specific embodiment
The following will be combined with the drawings in the embodiments of the present invention, carries out the technical scheme in the embodiment of the utility model
Clearly and completely describe.Obviously, the described embodiments are only a part of the embodiments of the utility model, rather than whole
Embodiment.Based on the embodiments of the present invention, those of ordinary skill in the art are without making creative work
Every other embodiment obtained, fall within the protection scope of the utility model.
As shown in Figure 1, water pump is equipped with water inlet 1, water outlet 2, impeller portion 3, tapered thread is equipped in the side of water inlet 1
Mouth 4, is mounted therein with taper screw plug 5.
As shown in Fig. 2, being the overall structure schematic diagram of the utility model.At the close impeller portion 3 of water inlet 1, along water pump
Inner wall is equipped with annular slot 6；The position of the annular slot 6 is set to the bottom level altitude range of the tapered thread mouth 4
It is interior；Net-filter assembly 7 is equipped in the annular slot 6；The net-filter assembly 7 includes circlip 71, the circlip 71
After being unfolded under natural conditions, it can be caught in the annular slot 6；Strainer 72, the strainer 72 are equipped on circlip 71
Dome arch 73 is formed along water (flow) direction, i.e., when pump working, particulate contaminant in water flow can be by the filter of the utility model
Net 72 is stopped, and with water (flow) direction, is limited in the dome arch 73.
When in use, since net-filter assembly 7 is equipped with circlip 71, and strainer 72 itself is also flexible material, to elasticity
Retaining ring 71 carries out pinching crimping contracting, can be entered in water pump by narrow tapered thread mouth 4 from outside, and due to annular slot
6 presence after circlip 71 enters in water pump, is unfolded, it is easy to will enter annular slot 6, and be limited naturally
Wherein.
The strainer 72 is flexible filter screen, is preset as dome arch, but during the installation process, is likely to be at indefinite form,
As the work of water pump is opened, water flow movement will be by the automatic band of strainer 72 to the front in water flow movement direction, to be formed pre-
If dome arch.
As shown in Figure 3, it is preferred that in direction of the circlip 71 far from tapered thread mouth 4, be equipped with draw ring arrangement 74；Institute
It states draw ring arrangement 74 to be located on the planar annular of the circlip 71, is equipped with through-hole 75 among it.
When being dismantled to net-filter assembly 7, needs first to remove taper screw plug 5 using tool, barbed tool is passed through into taper
Screw thread mouth 4 protrudes into the pump housing, in the through-hole 75 for catching on the draw ring arrangement 74, applies pulling force；At this point, 74 stress of draw ring arrangement,
It drives circlip 71 to generate deformation, and then circlip 71 is pulled out from annular slot 6, and then enter tapered thread mouth 4
In, finally take out the net-filter assembly 7.Due to the setting of draw ring arrangement 74, can in the case where not destroying strainer 72,
Net-filter assembly 7 can be taken out, easy to disassemble, cleaning net-filter assembly 7, to realize reuse.
While there has been shown and described that the embodiments of the present invention, for the ordinary skill in the art,
It is understood that these embodiments can be carried out with a variety of variations in the case where not departing from the principles of the present invention and spirit, repaired
Change, replacement and variant, the scope of the utility model is defined by the appended claims and the equivalents thereof.
