Sliding-vane pump
Technical field
The invention belongs to pump field, it is related to a kind of sliding-vane pump.
Background technology
Sliding-vane pump is called vane pump, scraping blade pump, scraper pump.Majority is by the pump housing, internal rotor, stator, pump cover and slide plate group
Into.Its operation principle is slide plate to be made to be close to eccentric stator by centrifugal force, and cavity volume increases between two slide plates of entrance, and imbibition goes out
Cavity volume reduces between connecting a slide plate at mouthful, drain.There are the incomplete problems of drain for existing sliding-vane pump.
Invention content
It is completely and smart that a kind of smooth drain of slide plate slip is provided the invention aims to overcome the deficiencies in the prior art
Accurate sliding-vane pump.
In order to achieve the above objectives, the technical solution adopted in the present invention is:A kind of sliding-vane pump including the pump housing, is installed on
Slip sheet mechanism in the pump housing and the filter assemblies for being connected to pump housing water inlet upstream, the slip sheet mechanism include turning
Axis, slide and slide plate, the slide is cylindrical and offers thereon and penetrates through its own upper and lower end face and opening and radially extend
Sliding slot, the slide plate is slidably connected in the sliding slot, it is characterised in that:The side wall spacing of the sliding slot is from notch to slot bottom
Direction is successively decreased, and the length of side wall is successively decreased by notch phase slot bottom.
Another preferred embodiment is:Accommodating chamber is formed between the sliding slot and the sliding block, profit is equipped in the accommodating chamber
Consistent lubricant.
Another preferred embodiment is:The sidewall bottom of the sliding slot is equipped with oil outlet, and the slide is internally provided with connection
The oiling channel of the oil filler point, the oil filler point of the oiling channel are located at the end face of slide.
Another preferred embodiment is:The oiling channel stage casing has shoe cream room, and the shoe cream room is substantially spherical in shape, straight
Diameter is more than the diameter of oiling channel.
Another preferred embodiment is:The inner wall that the slide is connect with the shaft is equipped with oil outlet, the oil outlet
There is oil inlet passage between the shoe cream room.
Another preferred embodiment is:The filter assemblies include screen pipe, the filtering for being installed on the screen pipe entrance
Block and cover body on the filter block is covered at, multiple inlet openings are offered on the cover body, are equipped in the cover body multiple
Overhead gage being extended downwardly by cover body inside top surface and in a ring and upwardly extended by cover body inner bottom surface and in a ring
Lower baffle plate, the overhead gage and the lower baffle plate be arranged at intervals and between form meander configuration runner, outside the lower baffle plate
Multiple sewage draining exits are offered on the cover body bottom of circle.
Another preferred embodiment is:The lateral wall of the lower baffle plate is equipped with annular filter circle or spaced filtering
Piece.
By adopting the above-described technical solution, this laser tooth washing device has the following advantages compared with the prior art:Utilize sliding slot
Storage chamber of the accommodating chamber formed between the sliding block as lubricating grease so that slide plate smooth can precisely skid off, and reach drain
Complete purpose.

Specific embodiment
The preferred embodiment of the invention is described in detail below in conjunction with attached drawing.
Sliding-vane pump including the pump housing 20, the slip sheet mechanism being installed in the pump housing 20 and is connected to pump housing water inlet upstream
Filter assemblies.
As shown in Figure 2,3, slip sheet mechanism includes shaft 21, slide 22 and slide plate 23, and slide 22 is cylindrical and opens thereon
It is slidably connected in sliding slot 24 equipped with its own upper and lower end face of perforation and the open sliding slot 24 radially extended, slide plate 23, sliding slot
24 side wall spacing is successively decreased from notch to slot bottom direction, and the length of side wall is successively decreased by notch phase slot bottom.Sliding slot 24 and sliding block it
Between form accommodating chamber, lubricating grease is equipped in accommodating chamber.The sidewall bottom of sliding slot 24 is equipped with oil outlet 25, and slide 22 is internally provided with
The oiling channel 26 of oil filler point 27 is connected, the oil filler point 27 of oiling channel 26 is located at the end face of slide 22.26 stage casing of oiling channel
With shoe cream room 28, shoe cream room 28 is substantially spherical in shape, has a diameter larger than the diameter of oiling channel 26.Slide 22 is connect with shaft 21
Inner wall be equipped with oil outlet 29, between oil outlet 29 and shoe cream room 28 have oil inlet passage 210.
As shown in figure 4, immersible pump filter assemblies include screen pipe 1, be installed on 1 entrance of screen pipe filter block 2 and
The cover body 3 on filter block 2 is covered at, multiple inlet openings are offered on the side wall of cover body 3, the region that inlet opening is distributed with is water inlet
Area 4, in cover body 3 equipped with multiple being extended downwardly by 3 inside top surface of cover body and overhead gage 5 in a ring and by cover body 3 inside
Bottom surface upwardly extends and lower baffle plate in a ring 6, overhead gage 5 and lower baffle plate 6 be arranged at intervals and between formed meander configuration runner,
Multiple sewage draining exits 7 are offered on 3 bottom of cover body of 6 outer ring of lower baffle plate.The lateral wall of lower baffle plate 6 is equipped with annular filter circle
Or spaced filter 8.
The above is only the preferred embodiment of the present invention, and protection scope of the present invention is not limited merely to above-mentioned implementation
Example, all technical solutions belonged under thinking of the present invention all belong to the scope of protection of the present invention.It should be pointed out that for the art
