Principle is described as follows used by pump assembly of the present invention：
Compressor in actual work, between slide plate 2 and sliding vane groove 34 in the gap of exhaust outlet 31 pressure FSHy compared with
Height, and pressure FSHx is relatively low in the gap of air entry 32, due to gas force imbalance, cause slide plate 2 and sliding vane groove 34 it
Between directed force F R, lead between slide plate 2 and sliding vane groove 34 that there are frictional force FRt.
When compressor low frequency operates, slide plate 2, which is detached from roller 5 and can be happened at slide plate 2, moves downward process (towards roller 5)
In, 2 stress of slide plate is as shown in Figure 7 at this time.Active force between slide plate 2 and roller 5 is：FG=FW-FRt, wherein FW are slide plate 2
2 both ends gas load of suffered slide plate, FW determine by compressor operating operating mode, frictions of the FRt between slide plate 2 and sliding vane groove 34
Power can cause slide plate 2 to be detached from roller 5 with 2 direction of motion of slide plate on the contrary, this power.FG when slide plate 2 is detached from roller 5<0,
It can realize that increase FG, reduction frictional force are needed by reducing slide plate 2 and sliding by reducing frictional force FRt (support reaction FR causes)
Support reaction FR between film trap 34 is realized.
2 horizontal direction force of slide plate balances, and has FR+FSHx=FSHy+FH, then FR=FSHy+FH-FSHx, wherein
FSHx is the gas pressure suffered by the suction side of slide plate 2；FH, FSHy are compressed side gas load suffered by slide plate 2, by compressor
The operating mode that works determines.By the way that high pressure gas is introduced slide plate 2 with sliding vane groove 34 close to the gap of air entry 32, may be implemented to increase
Big FSHx, to realize the frictional force FRt reduced between slide plate 2 and sliding vane groove 34, increases and slides then can reduce FR accordingly
Directed force F G between piece 2 and roller 5 is detached to control slide plate 2 with roller 5.
Obviously, the above embodiments are merely examples for clarifying the description, and does not limit the embodiments.It is right
For those of ordinary skill in the art, can also make on the basis of the above description it is other it is various forms of variation or
It changes.There is no necessity and possibility to exhaust all the enbodiments.And it is extended from this it is obvious variation or
It changes still within the protection scope of the invention.
