Abstract

The utility model relates to a two-stage fluid ring type vacuum pump which belongs to a liquid ring pump. The utility model is mainly composed of a main shaft, an air pumping and an air discharging housings, an air pumping and an air discharging impellers, an air pumping and an air discharging intermediate bodies, an air pumping and an air discharging through plates, and a packing set. The air pumping and the air discharging housings are connected with the sleeve seat of the packing set into integration, the air pumping and the air discharging through plates are combined with the air pumping and the air discharging housings in a divided mode, and the air pumping intermediate body is combined with the air discharging intermediate body in a divided mode. The utility model has the advantages of simple structure, reliable performance, favorable sealing performance, high air pumping and discharging speed rate, high power, low noise, etc. Besides, no phenomenon of liquid and air leakage exists at positions from which shafts project out on a pump body, so that the product quality is enhanced further.

Description

Two-stage fluid ring type vacuum pump
A kind of two-stage liquid-ring vacuum pump belongs to a kind of water-ring pump.
Before the utility model is made, in prior art, liquid-ring vacuum pump mainly by take out, exhaust casing, take out, exhaust impeller, intermediate, packing is formed.Pump drainage gas housing separates assembling with block set, and saturating plate of housing and pump drainage gas shell combination one are taken out, the exhaust intermediate is an integral body.This structure liquid-ring vacuum pump quality instability, there are leakage and gas leak phenomenon in pump housing shaft place, and speed and vacuum pump do not reach requirement, directly influence quality of product.
The purpose of this utility model is to overcome above-mentioned deficiency, thereby a kind of simple in structure, high power, low noise, two-stage liquid-ring vacuum pump that precision is high are provided.
The utility model mainly by main shaft (1), take out, exhaust casing (2), (3), take out, exhaust impeller (4), (5), take out, exhaust intermediate (6), (7), take out, the saturating plate of exhaust (8), (9), connecting tube (12), packing (11) is formed.Take out, exhaust casing (2), (3) be connected as a single entity with packing block set (11) block set, take out, the saturating plate of exhaust casing (8), (9) with take out, exhaust casing (2), (3) split combination, intermediate of bleeding (6) and exhaust intermediate (7) split combination.
Description of drawings:
Fig. 1 is the utility model plan view:
Fig. 2 is the utility model plan view:
Embodiment during following the utility model is incited somebody to action in conjunction with the accompanying drawings is further described:
The utility model mainly is made up of extraction pump and exhaust pump.Extraction pump is made up of the housing of bleeding (2), the plate of bleeding (8), the impeller of bleeding (4), the intermediate of bleeding (6), extraction pump geosphere (15).Exhaust pump is made up of intermediate (7), exhaust impeller (5), the saturating plate of exhaust (9), exhaust casing (3), exhaust pump geosphere (16).Main shaft (1) is gone up dress and is taken out, exhaust impeller (4), (5), all fixedly connected with axle, take out, exhaust casing (2), (3) be connected as a single entity with packing (11) block set, take out, the saturating plate of exhaust (8), (9) with, take out, exhaust casing (2), (3) split combination, take out, exhaust intermediate (6), (7) split combination, take out, exhaust impeller (4), (5) locate to be equipped with and take out, exhaust pump geosphere (15), (16), antero posterior axis bearing (10) is separately fixed at takes out, exhaust casing (2), (3) outside eccentric position is taken out, exhaust casing (2), (3) seal arrangement of packing (11) all is equipped with at the shaft place.The air-flow UNICOM of extraction pump and exhaust pump by connecting tube (12) with take out, exhaust intermediate (6), (7) be connected.Take out, exhaust casing (2), (3) outside be equipped with take out, exhaust port (13), (14).
Main shaft (1) is positioned at the eccentric position of the pump housing by antero posterior axis bearing (10), then impeller with take out, the eccentric minimum distance of exhaust pump geosphere (15), (16), formed enclosed point by pendular ring, impeller turns clockwise, in the half cycle that begins from enclosed point, the pump housing is in negative pressuren zone, back half-turn just becomes zone of positive pressure, impeller side is close to plate, become pumping window at the negative pressuren zone window, window at zone of positive pressure becomes exhaust window, has just finished the work that vacuumizes of pump drainage gas like this in the one-level pump.Working solution is water or oil, enters extraction pump from the housing of bleeding (2), through take out, exhaust intermediate (6), (7), enter exhaust pump again, discharge with gas from exhaust port (14).Exhaust port (14) locates that the gas-liquid part flow arrangement is arranged in addition, and the working solution of discharge is entered in the vacuum pump by the extraction pump housing behind cold filtration again.
Compared with the prior art the utility model has the following advantages: 1, simple in structure, dependable performance, precision height, good seal performance; 2, have that height is taken out, deflation rate, high power, low noise; 3, pump housing shaft place does not have leakage, gas leak phenomenon, has improved further product quality.

Claims (2)

1, a kind of two-stage liquid-ring vacuum pump is by main shaft (1), take out, exhaust casing (2), (3), take out, exhaust impeller (4), (5), take out, exhaust intermediate (6), (7), take out, the saturating plate of exhaust (8), (9), packing (11) is formed, and it is characterized in that taking out, exhaust casing (2), (3) connect as one with packing (11) block set, take out, the saturating plate of exhaust (8), (9) with take out, exhaust casing (2), (3) split combination, intermediate of bleeding (6) and exhaust intermediate (7) split combination.
2, two-stage liquid-ring vacuum pump according to claim 1, it is characterized in that describedly taking out, exhaust casing (2), (3) outside be equipped with take out, exhaust port (13), (14).
