Description
Technical Field
The utility model relates to a vacuum pump technical field especially relates to a water ring vacuum pump's connection structure.
Background
at present, a connection structure of a 2BEP series water ring vacuum pump is generally connected by six pull rods, and due to the fact that the connection structure is simple in process, looseness of a connection position of a whole single pump is easily caused when the connection structure is used, particularly, the phenomena of vacuum pressure attenuation and water leakage of a vacuum pump body frequently occur in the process of pumping work of the vacuum pump, and the operation of a whole unit is influenced.
This problem has not been solved well.
SUMMERY OF THE UTILITY MODEL
in order to overcome the above-mentioned not enough of prior art, the utility model provides a water ring vacuum pump's connection structure solves current vacuum pump connection not hard up, the problem of pump body gas leakage.
The invention is realized by the following technical scheme:
the utility model provides a connection structure of water ring vacuum pump, includes the pump body, the both sides of the pump body respectively are equipped with a pump cover, the pump cover top is equipped with the pump cover flange near distributor plate one side, the pump body both ends outside is equipped with the pump body flange, it is fixed through a plurality of bolted connection between pump body flange and the pump cover flange, the distributor plate is located between pump body flange and the pump cover flange.
Furthermore, the pump body flange is provided with a limiting bayonet at one side close to the distributing plate, and the limiting bayonet is matched with the protruding part on the distributing plate.
Furthermore, the pump body flange and the pump cover flange are correspondingly provided with flange holes, and the two corresponding flange holes are fixedly connected through bolts.
Furthermore, the distance between two symmetrical flange holes on the pump body flange is larger than the outer diameter of the distribution plate.
Compared with the prior art, the beneficial effects of the utility model reside in that:
The utility model provides a connection structure of water ring vacuum pump on current 2BE1 model vacuum pump connection structure's basis, improves the structure of pump cover, the pump body and break plate, adopts flange joint to replace traditional pull rod to BE connected between the pump cover and the pump body, increases vacuum pump monomer sealing performance, solves the problem of pump body gas leakage, stabilizes the normal operating of whole unit.
Drawings

Detailed Description
The following examples are presented to illustrate certain embodiments of the invention and should not be construed as limiting the scope of the invention. The present disclosure may be modified from materials, methods, and reaction conditions at the same time, and all such modifications are intended to be within the spirit and scope of the present disclosure.
As shown in fig. 1, the existing 2BEP series water ring vacuum pump connection structure includes a pump body 1, pump covers 2 and distribution plates 3, a pull rod 8 is disposed between the two pump covers 2, the pull rod 8 penetrates through the distribution plates 3, and both ends of the pull rod 8 are locked on the pump covers 2 through nuts.
As shown in fig. 2-3, the connection structure of a water ring vacuum pump of this application, including the pump body 1, the both sides of the pump body 1 respectively are equipped with a pump cover 2, 2 tops of pump cover are equipped with pump cover flange 5 near 3 one sides of break plate, 1 both ends outside of the pump body is equipped with pump body flange 4, it is fixed to connect through a plurality of bolts 6 between pump body flange 4 and the pump cover flange 5, break plate 3 is located between pump body flange 4 and the pump cover flange 5.
The pump body flange 4 is provided with a limiting bayonet 7 at one side close to the distributing plate 3, and the limiting bayonet 7 is matched with a convex part on the distributing plate 3 for installation, so that the distributing plate 3 can be quickly installed, and the alignment is more convenient.
Correspond on pump body flange 4 and the pump cover flange 5 and be equipped with the flange hole, connect fixedly through bolt 6 between two corresponding flange holes, the hole pitch between two symmetrical flange holes on pump body flange 4 is greater than the external diameter of break plate 3, and bolt 6 only passes pump body flange 4 and pump cover flange 5, compares in current pull rod connection vacuum pump, and pull rod 8 need pass the pull rod through-hole on the break plate 3, and this application design processing is simpler.
To sum up, adopt flange joint to replace traditional pull rod to be connected between the pump cover of this application and the pump body, not only easy dismounting increases vacuum pump monomer sealing performance moreover, solves the problem of pump body gas leakage and water leakage, stabilizes the normal operating of whole unit.
The above only is the embodiment of the present invention, not limiting the patent scope of the present invention, all the equivalent structures or equivalent processes that are used in the specification and the attached drawings or directly or indirectly applied to other related technical fields are included in the patent protection scope of the present invention.
