Detailed Description
The present invention will now be described in further detail with reference to the accompanying drawings. These drawings are simplified schematic views illustrating only the basic structure of the present invention in a schematic manner, and thus show only the constitution related to the present invention.
Fig. 1 is a schematic structural view of the present invention.
As shown in the attached figure 1, the circulating water cooling type roots pump comprises a roots pump body 1, wherein a cooling water flow passage is arranged in the shell wall of the shell of the roots pump body 1, a cooling water inlet 2 and a cooling water outlet 3 are arranged on the shell of the roots pump body 1, the cooling water inlet 2 and the cooling water outlet 3 are both communicated with the cooling water flow passage, and a vacuumizing port 4 is arranged on the shell of the roots pump body 1.
The vacuum-pumping port 4 is provided with a flange 5. The flange passes through bolted connection to be fixed in pipeline one end, and the pipeline other end is connected on the vacuum pump, and the vacuum pump can give roots pump evacuation.
The housing of the Roots pump body 1 is provided with a plurality of lifting rings 6.
The bottom of the shell of the Roots pump body 1 is provided with a plurality of support legs 7, and the support legs 7 are provided with bolt holes.
The vertical section of the cooling water flow passage is in the shape of two rings which are symmetrical with each other. Through the cooling water flow passage with the shape, a full-wrapping water cooling structure can be formed. The cooling water pump enters cooling water into the cooling water flow channel through the cooling water inlet 2 and then flows out through the cooling water outlet 3 to form a cooling water circulation system. Therefore, the cooling area can be increased to the maximum extent, and the cooling efficiency is improved. And the installation of a cooling water coil is eliminated, thereby simplifying the structure.
In light of the foregoing description of the preferred embodiment of the present invention, many modifications and variations can be made by the worker in the light of the above teachings without departing from the spirit of the utility model. The technical scope of the present invention is not limited to the content of the specification, and must be determined according to the scope of the claims.
