The single-stage sliding vane rotary vacuum pump comprises a pump shell and a motor, wherein the pump shell and the motor are connected and fixed by virtue of a support, a cylinder body and an end cover are arranged in the pump shell, the end cover is fixed on the cylinder body, the pump shell is internally provided with a pump rotator which is eccentrically arranged relatively to the cylinder body, the pump rotor is internally provided with a rotary vane, the pump rotor is fixedly connected with an output shaft of the motor, and the pump rotor is fixed on the support by virtue of a bearing. The single-stage sliding vane rotary vacuum pump has the advantages of compact structure, small size and light weight.
Description
Technical field
The utility model belongs to field of mechanical technique, has related to a kind of single-stage sliding vane rotary vacuum pump.
Background technique
Sliding vane rotary vacuum pump (abbreviation sliding vane rotary pump) is a kind of oil seal type oil-sealed rotary pump, belongs to Roughing pump.It can use separately, also can be used as the fore pump of other high vacuum pump or ultrahigh vacuum pump.It has been widely used in metallurgy, machinery, military project, electronics, chemical industry, light industry, oil and medicine etc. and has produced and scientific research department.Sliding vane rotary pump can extract the dry gas in the seal container, if with the gas ballasting device, can also extract a certain amount of condensable gas.
The single-stage sliding vane rotary vacuum pump comprises motor and pump housing two-part, makes vacuum environment by the work of the motor driving pump housing.Pump body structure complexity, the volume of the single-stage sliding vane rotary vacuum pump that uses are big at present, quality is heavy, and it is very inconvenient to use.
Summary of the invention
There are the problems referred to above in the utility model at existing technology, has proposed a kind of compact structure, little, the lightweight single-stage sliding vane rotary vacuum pump of volume.
The utility model is realized by following technical proposal: a kind of single-stage sliding vane rotary vacuum pump, comprise pump case and motor, be connected and fixed by support between pump case and the motor, it is characterized in that, be provided with cylinder body and end cap in the described pump case, described end cap is fixed on the described cylinder body, have in the described pump case with respect to the eccentric pump rotor that arranges of cylinder body, be provided with blade in the described pump rotor, described pump rotor is fixedlyed connected with the output shaft of described motor, described pump rotor by bearing fixing on described support.
When machine operation, rotor was done eccentric rotary before the output shaft of motor drove in front-bank rotor housing, the centrifugal action that produces when rotating in front-bank rotor housing because of rotor before being subjected to, before blade can adherent rotation in front-bank rotor housing, and then preceding blade changes the gas pressure intensity in the front-bank rotor housing, thereby constantly ambient atmos is sucked in the front-bank rotor housing and discharge, finish the vacuum of equipment.
In above-mentioned a kind of single-stage sliding vane rotary vacuum pump, described pump case top has suction port, and described pump case sidepiece has dial.
Compared with prior art, this single-stage sliding vane rotary vacuum pump has compact structure, little, the lightweight advantage of volume.
Description of drawings
Fig. 1 is the structural representation of this single-stage sliding vane rotary vacuum pump.
Among the figure, 1, motor; 2, output shaft; 3, pump case; 4, cylinder body; 5, pump rotor; 6, blade; 7, bearing; 8, support; 9, end cap; 10, suction port; 11, dial.
Embodiment
Below be specific embodiment of the utility model, and by reference to the accompanying drawings the technical solution of the utility model be further described, but the utility model is not limited to these embodiments.
A kind of single-stage sliding vane rotary vacuum pump as shown in Figure 1, comprise pump case 3 and motor 1, be connected and fixed by support 8 between pump case 3 and the motor 1, described pump case 3 tops have suction port 10, described pump case 3 sidepieces have dial 11, be provided with cylinder body 4 and end cap 9 in the described pump case 3, described end cap 9 is fixed on the described cylinder body 4, have in the described pump case 3 with respect to the cylinder body 4 eccentric pump rotors 5 that arrange, be provided with blade 6 in the described pump rotor 5, described pump rotor 5 is fixedlyed connected with the output shaft 2 of described motor 1, and described pump rotor 5 is fixed on the described support 8 by bearing 7.
When motor 1 work, the output shaft 2 of motor 1 drives pump rotor 5 and do eccentric rotary in cylinder body 4, the centrifugal action that produces when rotating in cylinder body 4 because being subjected to pump rotor 5, blade 6 meeting adherent rotations in cylinder body 4, and then the gas pressure intensity in the blade 6 change cylinder bodies 4, thereby constantly ambient atmos is sucked in the cylinder body 4 and discharge, finish the vacuum of equipment.This single-stage sliding vane rotary vacuum pump has compact structure, little, the lightweight advantage of volume.
Specific embodiment described herein only is that the utility model spirit is illustrated.The utility model person of ordinary skill in the field can make various modifications or replenishes or adopt similar mode to substitute described specific embodiment, but can't depart from spirit of the present utility model or surmount the defined scope of appended claims.
Although this paper has used terms such as motor 1, output shaft 2, pump case 3, cylinder body 4, pump rotor 5, blade 6, bearing 7, support 8, end cap 9, suction port 10, dial 11 morely, do not get rid of the possibility of using other term.Using these terms only is in order to describe and explain essence of the present utility model more easily; They are construed to any additional restriction all is contrary with the utility model spirit.
