Abstract
The utility model discloses a kind of three-level pendular ring pump groups, liquid rotary pump and three Double shaft-extension liquid rotary pumps are stretched including two motor for double-ended drive, two single shafts, motor for double-ended drive and single shaft, which are stretched, is arranged gear between liquid rotary pump, Double shaft-extension liquid rotary pump, gear shift transmission mechanism is set between two Double shaft-extension liquid rotary pumps, and motor for double-ended drive, gear, single shaft, which are stretched, to be connected between liquid rotary pump and Double shaft-extension liquid rotary pump by bindiny mechanism.The utility model stretches liquid rotary pump using two motor for double-ended drive, two single shafts and three Double shaft-extension liquid rotary pumps form two groups of thtee-stage shiplock pendular ring pump configurations, so that the intensity that liquid rotary pump vacuumizes improves, so that lobe pump is not easy to make overload after opening, prolonged use will not enable Roots's pump seizure damage, in addition it can make one group of liquid rotary pump that problem occur, another group can work on, so as to avoid problem occurs in production process.
Description
Technical field
The utility model belongs to pendular ring pump technical field, and in particular to a kind of three-level pendular ring pump group.
Background technique
Liquid rotary pump is a kind of thick vacuum pumping pump for using liquid as working media, through the prime and Qi Lian frequently as lobe pump
It closes and uses, but since the intensity of single-stage liquid rotary pump vacuumized is inadequate, cause vacuum degree inadequate, open lobe pump at this time and be easy
The overload of lobe pump is caused, Roots's pump seizure can be made to damage for a long time, furthermore once generation problem cannot for one group of liquid rotary pump
Continuous work, leads to that problem occurs in production process, therefore a kind of multistage and to be capable of the pendular ring pump group of continuous work be desirable
's.
Utility model content
In view of the deficienciess of the prior art, the utility model provides a kind of three-level pendular ring pump group.
The utility model is achieved through the following technical solutions: a kind of three-level pendular ring pump group, including two Double shaft-extension electricity
Machine, two single shafts stretch liquid rotary pump and three Double shaft-extension liquid rotary pumps, and the motor for double-ended drive and the single shaft stretch liquid rotary pump, described pair
Axis, which is stretched, is arranged gear between liquid rotary pump, gear shift transmission mechanism is arranged between two Double shaft-extension liquid rotary pumps, described
Motor for double-ended drive, the gear, the single shaft, which are stretched, to be connected between liquid rotary pump and the Double shaft-extension liquid rotary pump by bindiny mechanism
It connects.
Preferably, it is to be arranged in series that a single shaft, which stretches liquid rotary pump and two Double shaft-extension liquid rotary pumps,.
Preferably, the bindiny mechanism is shaft coupling.
Preferably, the gear is belt pulley set.
Compared with prior art, the utility model has the beneficial effects that the utility model uses two motor for double-ended drive, two
Platform single shaft stretches liquid rotary pump and three Double shaft-extension liquid rotary pumps form two groups of thtee-stage shiplock pendular ring pump configurations, and three-level pendular ring pump configuration makes
The intensity that liquid rotary pump vacuumizes improves, so that lobe pump is not easy to make overload after opening, prolonged use will not enable sieve
The damage of thatch pump seizure, once two groups of series connection pendular ring pump configurations can make one group of liquid rotary pump generation problem, another group can continue
Work, so as to avoid problem occurs in production process.
Detailed description of the invention
Fig. 1 is the overall structure diagram of the utility model.
In attached drawing: 1. motor for double-ended drive；2. single shaft stretches liquid rotary pump；3. Double shaft-extension liquid rotary pump；4. gear；5. the machine of connection
Structure；6. gear shift transmission mechanism.
Specific embodiment
Such as a kind of three-level pendular ring pump group shown in FIG. 1 in Figure of description, including two motor for double-ended drive, 1, two single shaft
Liquid rotary pump 2 and three Double shaft-extension liquid rotary pumps 3 are stretched, motor for double-ended drive 1 and single shaft are stretched to be arranged between liquid rotary pump 2, Double shaft-extension liquid rotary pump 3
Gear 4, is arranged gear shift transmission mechanism 6 between two Double shaft-extension liquid rotary pumps 3, motor for double-ended drive 1, gear 4, single
Axis, which is stretched, to be connected between liquid rotary pump 2 and Double shaft-extension liquid rotary pump 3 by bindiny mechanism 5.
A kind of three-level pendular ring pump group in the implementation case, a single shaft stretch liquid rotary pump 2 and two Double shaft-extension liquid rotary pumps 3 for string
Connection setting.
A kind of three-level pendular ring pump group in the implementation case, bindiny mechanism 5 are shaft coupling.
A kind of three-level pendular ring pump group in the implementation case, gear 4 are belt pulley set.
Concrete operating principle: when opening motor for double-ended drive 1, the single shaft being connect with its left end stretch liquid rotary pump 2 and with its right side
One Double shaft-extension liquid rotary pump 3 of end connection operates simultaneously, and the Double shaft-extension liquid rotary pump 3 of operating passes through gear shift transmission mechanism simultaneously
6 drive another Double shaft-extension liquid rotary pump 3 running connecting with its right end, and the gear 4 between liquid rotary pump and motor is arranged in
The revolving speed of adjustable liquid rotary pump is connected between liquid rotary pump, gear 4 and motor by shaft coupling, when one group of three-level pendular ring
Pump group can disconnect shaft coupling when breaking down, and use another group of three-level pendular ring pump group.
In conclusion the preferred embodiment of only the utility model, is not used to limit the utility model implementation
Range, all equivalent changes according to carried out by shape described in the utility model claims range, construction, feature and spirit with repair
Decorations, should be included in the scope of the claims of the utility model.
