Abstract
The invention relates to a small single-stage water-ring vacuum pump, which includes a pump cover, a pump body, an impeller, a mechanical seal, a bearing support and a motor member. One end of the bearing support is firm-jointed with the motor by a bolt and the other end of the bearing support is firm-jointed with the pump body by a bolt. On the bearing support is mounted a bearing, which is sleeved on the mainshaft of the motor. The impeller and the mechanical seal in the pump body are direct mounted on the mainshaft of the motor.
Description
[technical field]
The present invention relates to the water ring vaccum pump technical field, particularly a kind of horizontal small size single stage single water suction ring vacuum pump.
[background technique]
Existing single stage single water suction ring vacuum pump generally is the water ring vaccum pump that pump and electric machine main shaft is linked together by coupling.This water ring vaccum pump exists many deficiencys: because pump and motor connect by coupling, its structure is not compact, and floor space is big, and is difficult to guarantee that the pump axle is concentric fully.Shortcomings such as in addition, it is unreliable to move in addition, and working life is short, and Oscillation Amplitude is big, and noise is big.
[summary of the invention]
Purpose of the present invention is exactly will solve above-mentioned deficiency and a kind of small size single stage single water suction ring vacuum pump is provided.Adopt the pump coaxial configuration, it is big to have solved existing water ring vaccum pump floor space, and the pump axle is not exclusively concentric, and is reliable, vibrates for a short time, and noise is low.
For achieving the above object, the present invention proposes a kind of small size single stage single water suction ring vacuum pump, comprise pump cover, the pump housing, impeller, mechanical seal, bearing bracket, motor component, bearing bracket 9 one ends adopt bolt to connect motor 12, bearing 11 is housed on the bearing bracket 9, bearing 11 is enclosed within on the electric machine main shaft 14, and bearing bracket 9 the other ends adopt bolt to connect the pump housing 4, and impeller 5, mechanical seal 8 directly are contained on the electric machine main shaft 14 in the pump housing.
The mode that impeller 5 and electric machine main shaft 14 adopts interference fit and add key is connected.
Described motor 12 adopts the extension shaft motor, and electric machine main shaft 14 adopts stainless steel shaft.
The bearing bracket 9 that is positioned at the pump housing 4 one sides is provided with lip type oil sealing 10 with electric machine main shaft 14 connection places.
Rubber bellows seal is adopted in described mechanical seal 8, comes localization machine block circle 7 by key.
The present invention compared with prior art except all advantages with conventional single stage single water suction ring pump, also possesses the characteristics that following conventional single stage single water suction ring pump does not possess:
1. the present invention is the coaxial installation of pump, and the floor space of unit is little, saves the pump house floor area, and pump house infrastructure investment cost is low.
2. the electric machine stand below is provided with special lower margin cushion block, need not the particular design base, and unit can directly be installed on the basis.
3. electric machine main shaft adopts stainless steel shaft, and Never-rusty guarantees that electric machine main shaft is not subjected to the corrosion of general medium.
4. impeller and electric machine main shaft interference fit, and the mode that adds key connects, less interference guarantees that impeller does not have axial float, by the key transmitting torque, strengthens the reliability of pump operation.
5. the bearing of motor component back flow side strengthens design, bears the axial force that produces in the operation process, the structure uniqueness, and unit operation is steady.
6. electric-motor-driving step bearing support is provided with lip type oil sealing, prevents that the leakage of axle envelope from causing the bearing water inlet.
[description of drawings]
Fig. 1 is a structural representation of the present invention.
Referring to Fig. 1,1 is pump cover, and 2 are the cavitation erosion guard member, and 3 is distributor, and 4 is the pump housing; 5 is impeller, and 6 is key, and 7 is machine block circle, and 8 are mechanical seal; 9 is that bearing bracket, 10 is that lip type oil sealing, 11 is that bearing, 12 is motor, and 13 is the lower margin cushion block, and 14 is electric machine main shaft, and 15 is electric machine stand.
[specific embodiment]
Referring to Fig. 1, motor of the present invention adopts Y2 type extension shaft motor, and electric machine main shaft adopts stainless steel shaft.Motor 12, bearing bracket 9 and the pump housing 4 usefulness bolt link together, adopt bolt to connect between the pump housing 4 and the pump cover 1, bearing 11 is housed on the bearing bracket 9, bearing 11 is supporting on electric machine main shaft 14, the bearing bracket 9 that is positioned at the pump housing 4 right sides is provided with lip type oil sealing 10 with electric machine main shaft 14 connection places, prevents that the leakage of axle envelope from causing the bearing water inlet; Impeller 5 direct heat in the pump housing are placed on the motor shaft and add key, be positioned on the electric machine main shaft 14 of the pump housing and also be equipped with mechanical seal 8, rubber bellows seal is adopted in mechanical seal, come localization machine block circle 7 by key, have hole of base angle on the electric machine stand 15 of motor 12 bottoms, the lower margin cushion block 13 of the below of electric machine stand 15 is connected with motor base by screw.
