Abstract

The utility model discloses a kind of vacuum pumping device, it comprises tracheae and vacuum pump, described tracheae comprises the first tracheae, the second tracheae and the 3rd tracheae, described vacuum pump comprises the first vacuum pump, the second vacuum pump and the 3rd vacuum pump, described first tracheae is connected with the first vacuum pump, second vacuum pump is connected to the first tracheae by the second tracheae, and the 3rd vacuum pump is connected with the second tracheae by the 3rd tracheae.The utility model is in parallel with the first vacuum pump and by the branch being connected to the first tracheae, effectively can increase the degree of vacuum of jar by second vacuum pump, only needs the vacuum pump utilizing existing power, does not need to buy powerful vacuum pump in addition, save cost.

Description

A kind of vacuum pumping device
Technical field
The utility model relates to a kind of vacuum pumping device.
Background technique
My department needs the jar using certain vacuum degree when producing pharmaceutical intermediate, in use, when existing vacuum pump vacuumizes jar, degree of vacuum can't reach requirement, and it is too high again to buy more high-power vacuum pump cost.
Summary of the invention
For the deficiencies in the prior art, the purpose of this utility model is to provide a kind of inexpensive and can realize the device of more condition of high vacuum degree equally.
For achieving the above object, the utility model have employed following technological scheme:
A kind of vacuum pumping device, it comprises tracheae and vacuum pump, described tracheae comprises the first tracheae, the second tracheae and the 3rd tracheae, described vacuum pump comprises the first vacuum pump, the second vacuum pump and the 3rd vacuum pump, described first tracheae is connected with the first vacuum pump, second vacuum pump is connected to the first tracheae by the second tracheae, and the 3rd vacuum pump is connected with the second tracheae by the 3rd tracheae.
Compared with prior art, the beneficial effects of the utility model main manifestations is:
The utility model is in parallel with the first vacuum pump and by the branch being connected to the first tracheae, effectively can increase the degree of vacuum of jar by second vacuum pump, only needs the vacuum pump utilizing existing power, does not need to buy powerful vacuum pump in addition, save cost.
Accompanying drawing explanation
Fig. 1 is the structural representation of the utility model one embodiment.
Embodiment
Below in conjunction with accompanying drawing and preferred embodiment, the utility model is more specifically described.
As shown in Figure 1, a kind of vacuum pumping device, it comprises tracheae and vacuum pump, described tracheae comprises the first tracheae 1, second tracheae 3 and the 3rd tracheae 5, described vacuum pump comprises the first vacuum pump 2, second vacuum pump 4 and the 3rd vacuum pump 6, described first tracheae 1 is connected with the first vacuum pump 2, and the second vacuum pump 4 is connected to the first tracheae the 1, three vacuum pump 6 by the second tracheae 3 and is connected with the second tracheae 3 by the 3rd tracheae 5.
By reference to the accompanying drawings the utility model preferred implementation is explained in detail above, but the utility model is not limited to above-mentioned mode of execution, in the ken that those of ordinary skill in the art possess, can also make a variety of changes under the prerequisite not departing from the utility model aim.
