Abstract
The utility model relates to a large air volume distributor vacuum pump has the distributor plate, sets up the installation through-hole at eccentric distributor plate center on the distributor plate, and installation through-hole both sides are seted up respectively and are the exhaust hole, the inlet port of narrow wide form down, the exhaust hole include the outer arc that uses the distributor plate center to form as the centre of a circle, use the installation through-hole center as the interior arc that the centre of a circle formed, outer arc and the equal circular arc in interior arc both ends are connected. The utility model discloses changed the structure that traditional exhaust hole adds the waist shape hole that a plurality of diameter direction are long, the narrow waist shape hole of circumferencial direction constitutes by the last exhaust hole of a waist drum form, on the last exhaust hole basis of original waist drum form, the interior outer circular arc that extends the upper exhaust hole ends in original lower extreme waist shape hole place position, form the upper narrow wide exhaust hole down of an integral form, when pressurizeing under conventional atmospheric pressure like this, can realize whole exhaust without the fender, exhaust continuity is good, reduced because do useless work and the extravagant energy that causes more.
Description
Technical Field
The utility model belongs to the technical field of the vacuum pump technique and specifically relates to a large air distributor vacuum pump.
Background
During operation of the vacuum pump, gas is sucked and discharged through a distributor, which is an important component of the vacuum pump, from suction to compression and finally discharged through rotation of an impeller. The structure of the exhaust hole formed in the existing vacuum pump distributor is that a plurality of waist-shaped holes with long diameter direction and narrow circumferential direction are arranged below an upper exhaust hole in a waist drum shape, and when the exhaust hole with the structure is pressurized under the conventional air pressure, the continuity in the exhaust process is poor, so that the phenomenon of wasting energy by applying more work is easily generated.
Disclosure of Invention
The to-be-solved technical problem of the utility model is: in order to overcome the defects in the prior art, the utility model provides an improve big air volume distributor vacuum pump of exhaust continuity.
The utility model provides a technical scheme that its technical problem adopted is: a vacuum pump of a large-air-volume distributor is provided with a distributor plate, wherein a mounting through hole at the center of an upper eccentric distributor plate is formed in the distributor plate, an air exhaust hole and an air inlet hole are formed in two sides of the mounting through hole respectively, the air exhaust hole and the air inlet hole are narrow in upper part and wide in lower part, the air exhaust hole comprises an outer arc formed by taking the center of the distributor plate as the center of a circle and an inner arc formed by taking the center of the mounting through hole as the center of a circle, and two ends of the outer arc and two ends of the inner arc are connected in an arc mode.
Preferably, the center of the mounting through hole is eccentric to the center of the distributor plate by 77 mm.
Further, the radius of the outer arc of the exhaust hole is 298mm, and the radius of the inner arc of the exhaust hole is 212 mm.
The utility model has the advantages that: the utility model discloses changed the structure that traditional exhaust hole adds the waist shape hole that a plurality of diameter direction are long, the narrow waist shape hole of circumferencial direction constitutes by the last exhaust hole of a waist drum form, on the last exhaust hole basis of original waist drum form, the interior outer circular arc that extends the upper exhaust hole ends in original lower extreme waist shape hole place position, form the upper narrow wide exhaust hole down of an integral form, when pressurizeing under conventional atmospheric pressure like this, can realize whole exhaust without the fender, exhaust continuity is good, reduced because do useless work and the extravagant energy that causes more.
Drawings
The present invention will be further described with reference to the accompanying drawings and embodiments.
Fig. 1 is a schematic structural diagram of the present invention.
In the figure: 1. the distributor comprises a distributor plate, 2 parts of installation through holes, 3 parts of exhaust holes, 3-1 parts of outer arcs, 3-1 parts of inner arcs and 4 parts of air inlet holes.
Detailed Description
The present invention will now be described in further detail with reference to the accompanying drawings. These drawings are simplified schematic drawings and illustrate the basic structure of the present invention only in a schematic manner, and thus show only the components related to the present invention.
The large-air-volume distributor vacuum pump shown in fig. 1 is provided with a distributor plate 1 with the diameter of 1278mm, wherein a mounting through hole 2 is formed in the distributor plate 1, and the center of the mounting through hole 2 is upwards eccentric 77mm from the center of the distributor plate 1.
The two sides of the installation through hole 2 are respectively provided with an exhaust hole 3 and an air inlet hole 4, the exhaust hole 3 and the air inlet hole 4 are narrow at the top and wide at the bottom, the exhaust hole 3 comprises an outer arc 3-1 formed by taking the center of the distributor plate 1 as the center of a circle and an inner arc 3-2 formed by taking the center of the installation through hole 2 as the center of a circle, the radius of the outer arc 3-1 of the exhaust hole 3 is 298mm, the radius of the inner arc 3-2 is 212mm, and the two ends of the outer arc 3-1 and the two ends of the inner arc 3-2 are connected in an arc shape.
The utility model discloses changed the structure that traditional exhaust hole adds the waist shape hole that a plurality of diameter direction are long, the narrow waist shape hole of circumferencial direction constitutes by the last exhaust hole of a waist drum form, on the last exhaust hole basis of original waist drum form, the interior outer circular arc that extends the last exhaust hole ends in original lower extreme waist shape hole place position, form the upper narrow wide exhaust hole 3 down of an integral form, when pressurizeing under conventional atmospheric pressure like this, can realize whole exhaust without the fender, exhaust continuity is good, the waste energy that has reduced owing to do useless work more and cause has been reduced.
In light of the foregoing, it will be apparent to those skilled in the art from this disclosure that various changes and modifications can be made without departing from the spirit and scope of the invention. The technical scope of the present invention is not limited to the content of the specification, and must be determined according to the scope of the claims.
