3, slide plate is sliding friction with stator in rotary course, and wearing and tearing are big, and noise is big.
4, the application of the big flow of structural limitations of existing sliding vane pump, along with the increase of flow, the volume and weight of pump sharply increases.
The model utility content
The technical assignment of the technical problems to be solved in the utility model and proposition be overcome the slide plate contact position wearing and tearing of existing sliding vane pump big, be unfavorable for changing, noise is big, the defective that is not suitable for big flow, and a kind of slide plate external sliding vane pump is provided.For this reason, the utility model is by the following technical solutions:
Slide plate external sliding vane pump, comprise the pump housing, rotor, slide plate, pump shaft, the described pump housing has import, export and the pump chamber between described import and outlet in inside, described rotor places in the described pump chamber and is installed on the described pump shaft, it is characterized in that: offer one on the described pump housing and point to the chute of described rotor and mounting cover is established this chute on the pump housing slide plate lid, described slide plate is one and slides and to place in the described chute, end at the contiguous described rotor of described slide plate is installed the roller that contacts described rotor surface, by described rotor, slide plate, roller is divided into import volume that is communicated with import and the outlet volume that is communicated with outlet with described pump chamber.
As the optimization technique measure, the cross section of described rotor is ellipticity.
As the optimization technique measure, described rotor is installed on the described pump shaft by key.
As the optimization technique measure, drawing to described slide plate from described outlet volume has the pressure channel that makes described slide plate draw close to rotor.Concrete, a port of described pressure channel is opened in the outlet volume, and the another port of described pressure channel is opened in the position on the slide plate of being positioned at of described chute.
The beneficial effects of the utility model are:
1, slide plate quantity is few, has only a slice, and feasible little with the wearing and tearing of slide plate contact position, noise is also little simultaneously.
2, changing slide plate does not need to open pump cover, does not need to take apart bearing and mechanical seal, only need open the slide plate lid, extracts slide plate out and renews and get final product, and maintenance workload is little.
3, slide plate is rolling friction with rotor in rotary course, and it is little to wear and tear, and noise is little.
4, can be applied to big flow, the high viscosity operating mode.

Embodiment
Below in conjunction with Figure of description the utility model is described further.
Slide plate external sliding vane pump of the present utility model, as shown in Figure 1, it comprises the pump housing 1, rotor 2, slide plate 3, pump shaft 4, the pump housing 1 has import 5, outlet 6 and in inside between import 5 and the pump chamber that exports between 6, rotor 2 places in the pump chamber and is installed on the pump shaft 4, characteristics are: offer one on the pump housing 1 and point to the chute 7 of rotor 2 and mounting cover is established this chute 7 on the pump housing 1 slide plate lid 8, slide plate 3 is one and slides and to place in the chute 7, at an end of slide plate 7 adjacent rotor 2 roller 9 on contact rotor 2 surfaces is installed, by rotor 2, slide plate 3, roller 9 is divided into import volume 10 that is communicated with import 5 and the outlet volume 11 that is communicated with outlet 6 with pump chamber.During work, be with rotor 2 rotations by pump shaft 4, slide plate 3 does not together rotate with rotor 2, just slides in chute 7; Roller 9 is together done telescopic slide with slide plate 3, and roller 9 is done relative rolling along rotor 2 surfaces simultaneously; Flexible by slide plate 3 drives in rotors 2 rotation processes at pump shaft 4, and import volume 10 is becoming the big low pressure that forms always and from import 5 medium sucked, and outlet volume 11 is diminishing always and forming high pressure and from exporting 6 medium pumped the formation pumping capacity.And, after being opened, slide plate lid 8 can take out slide plate 3 easily, be convenient to change the direction of slide plate or transposing slide plate.
As further improving and replenishing to technique scheme, the utility model also comprises following additional technical characteristics, though Fig. 1 has comprised following all additional technical features, it is preferred embodiment of the present utility model, but the utility model is not limited to this situation, according to specifically acting on they is selected for use on the described technological scheme of epimere when implementing the utility model:
