Description
[technical field]
The utility model relates to the water ring vaccum pump technical field, particularly a kind of horizontal 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]
The purpose of this utility model is exactly will solve above-mentioned deficiency and a kind of horizontal 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 utility model proposes a kind of horizontal 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 utility model 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 utility model 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.
