Abstract
The utility model discloses a kind of vacuum pump distributor, comprise distributor body, distributor body is provided with kidney-shaped exhaust port, and kidney-shaped exhaust port adopts radial 3 row to arrange, between adjacent two row, kidney-shaped exhaust port staggers, and waist shaped hole is that circumferencial direction is long, diametric(al) is narrow.Vacuum pump distributor of the present utility model is when vacuum pump runs, and when vane rotary is by exhaust port position, all there is part waist shaped hole in each inswept cross section, achieves the continuity of exhaust like this, improves the efficiency of exhaust.
Description
Technical field
The utility model relates to a kind of vacuum pump distributor.
Background technique
Water ring vaccum pump operationally, carries out suction and the discharge of gas by distributor, in the process, gas is by the rotation of impeller, and from being drawn into, compression is last discharges, and distributor is a kind of vitals wherein during this period.The structure of existing vacuum pump distributor exhaust port is the waist shaped hole that diametric(al) is long, circumferencial direction is narrow, and waist shaped hole center line is in the uniform arrangement of circumferencial direction equal angles.This arrangement mode is when vane rotary, and some blades are successively by waist shaped hole region → aporate area → waist shaped hole region → aporate area, and in exhaust process, continuity is poor.The utility model provides a kind of distributor exhaust port arrangement efficiently, can improve the efficiency of exhaust.
Summary of the invention
The purpose of this utility model is to provide a kind of vacuum pump distributor efficiently, by changing exhaust port arrangement, improves the efficiency of exhaust.
For achieving the above object, the technical solution adopted in the utility model is as follows: a kind of vacuum pump distributor, comprise distributor body, distributor body is provided with kidney-shaped exhaust port, kidney-shaped exhaust port adopts radial 3 row to arrange, between adjacent two row, kidney-shaped exhaust port staggers, and described kidney-shaped exhaust port is that circumferencial direction is long, diametric(al) is narrow.
Vacuum pump distributor of the present utility model is when vacuum pump runs, and when vane rotary is by exhaust port position, all there is part waist shaped hole in each inswept cross section, achieves the continuity of exhaust like this, improves the efficiency of exhaust.
Accompanying drawing explanation
Fig. 1 is the structural representation of the utility model vacuum pump distributor.
Embodiment
As shown in Figure 1, vacuum pump distributor of the present utility model, comprises distributor body 1, distributor body is provided with kidney-shaped exhaust port 2, kidney-shaped exhaust port adopts radial 3 row to arrange, between adjacent two row, kidney-shaped exhaust port 2 staggers, and described kidney-shaped exhaust port 2 is that circumferencial direction is long, diametric(al) is narrow.
Vacuum pump distributor of the present utility model is when vacuum pump runs, and when vane rotary is by exhaust port position, all there is part kidney-shaped exhaust port in each inswept cross section, achieves the continuity of exhaust like this, improves the efficiency of exhaust.
