[0001] The present application relates to an air compressor, and more particularly to an integrated cooling base for a turbine compressor. Background Art

[0002] The multi-stage turbine compressor is a type of air compressor and is widely used in the industrial field. Since the multi-stage turbine compressor is used to compress air, a large amount of heat is released during the air compression process. Therefore, adding cooling between the stages of the multi-stage turbine compressor helps to improve the overall efficiency of the turbine and reduce power consumption.

This installation method requires a large space to install the equipment, and the cost of purchasing the cooler and the intermediate connecting pipes will also increase accordingly. Therefore, a cooler integrated base is designed and developed. Summary of the Utility Model

[0023] Next, the technical solutions in the embodiments of the present application will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present application. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present application.

[0024] It should be noted that when a component is referred to as being "connected" to another component, it can be directly connected to the other component or there may also be an intermediate component. When a component is considered to be "disposed on" another component, it can be directly disposed on the other component or there may be an intermediate component at the same time.

[0025] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by those of ordinary skill in the technical field to which this application belongs. The terms used in the specification of this application herein are only for the purpose of describing specific embodiments and are not intended to limit this application. The term "and / or" used herein includes any and all combinations of one or more of the related listed items.

[0026] Reference Figures 1 to 3 , in an embodiment of the present application, an integrated cooling turbine compressor base is disclosed. This base is used for the integration of the compressor 1, the heat exchanger 4, the speed increaser 2, and the oil station 3. One end of this base is provided with a cavity for installing the heat exchanger 4, and the other end is integrated with the oil station 3 to form an integral structure. The compressor 1 and the speed increaser 2 are fixed above this base, and corresponding to the end where the heat exchanger 4 is located, for directly connecting the compressor 1 and the heat exchanger 4 to improve the heat exchange efficiency. A cooling oil circuit is formed by connecting the oil station 3 and the speed increaser 2 through a pipeline.

[0027] Among them, the base has opposite front and rear ends.

[0028] The cavity for accommodating the heat exchanger 4 is provided at the front end of the base. For the convenience of cleaning and maintaining the heat exchanger 4, the heat exchanger 4 is detachably connected in the cavity.

[0029] Furthermore, as Figure 2As shown, the heat exchanger 4 adopts a heat exchange tube device, including a first heat exchange tube 41, a second heat exchange tube 42, and a third heat exchange tube 43. Correspondingly, the cavity includes a first heat exchange cavity, a second heat exchange cavity, and a third heat exchange cavity for heat dissipation. The first heat exchange tube 41, the second heat exchange tube 42, and the third heat exchange tube 43 are respectively located in the first heat exchange cavity, the second heat exchange cavity, and the third heat exchange cavity.

[0030] Correspondingly, the compressor 1 includes a first volute 11, a second volute 12, and a third volute 13 respectively built with impellers for pressurizing air.

[0031] The compressor 1 has an intake port 14 and an outlet port 15 opposite to each other. The first volute 11, the first heat exchange cavity, the second volute 12, the second heat exchange cavity, the third volute 13, and the third heat exchange cavity are connected in sequence. The inlet of the first volute 11 serves as the intake port 14, and the outlet of the third heat exchange cavity serves as the outlet port 15.

[0032] In some embodiments, the cooling oil circuit includes a main cooling oil circuit and an auxiliary cooling oil circuit.

[0033] Among them, the first end of the auxiliary cooling oil circuit is connected to the oil station 3, and the second end is connected to the speed increaser 2. From the first end to the second end, an oil auxiliary oil pump 72, a cooler 6, and a fine filter 5 are connected in sequence. The auxiliary cooling oil circuit is used to supply lubricating oil into the speed increaser.

[0034] The first end of the main cooling oil circuit is connected to the oil station 3, and the second end is connected to the speed increaser 2. From the first end to the second end, a main oil pump 71, an oil cooler 6, and a fine filter 5 are connected in sequence. The main cooling oil circuit is used to supply lubricating oil into the speed increaser instead of the auxiliary cooling oil circuit when the oil pressure exceeds the set value.

[0035] Furthermore, an oil heater 31 is provided at the rear end of the oil station 3 for heating the lubricating oil in the oil station 3 in a cold environment, avoiding the lubricating oil from being too viscous due to too low temperature and improving the fluidity of the lubricating oil.

[0036] Furthermore, an oil drain ball valve 32 is provided at the rear end of the oil station 3 for replacing the lubricating oil.

[0037] Furthermore, an oil mist processor 33 is also provided at the rear end of the oil station 3 for discharging the vaporized lubricating oil to avoid excessive pressure in the oil station 3. To enable the vaporized lubricating oil to be smoothly discharged through the oil mist processor 33, the oil mist processor 33 is connected to the upper end of the oil station 3.

[0038] It should be noted that when the turbo compressor operates, an electric motor is also required as an external power source, which drives the compressor 1 to work through transmission by the speed increaser 2. Therefore, an installation space for the electric motor is reserved on the base, and this installation space is located above the oil station 3 so that the drive shaft of the electric motor can be directly connected to the speed increaser 2.

[0039] Furthermore, at least one set of meshing speed increasing gear sets is arranged in the speed increasing gearbox 2. The working principle of the speed increasing gear set is as follows: it includes a large gear and a small gear. The large gear drives the small gear to rotate, and the angular velocity of the rotating shaft of the large gear is amplified to the angular velocity of the rotating shaft of the small gear at a certain ratio to obtain a speed increasing effect.

[0040] Among them, a coupling 21 is arranged on the rotating shaft of the large gear. The coupling 21 is located on the side close to the oil station 3. The rotating shaft of the large gear is connected to the driving shaft of the motor through the coupling 21, and the rotating shaft of the small gear starts the compressor 1 to work.

[0041] The technical features of the above-described embodiments can be combined arbitrarily. For the sake of brevity of description, not all possible combinations of the technical features in the above-described embodiments are described. However, as long as there is no contradiction in the combination of these technical features, it should be considered as the scope described in this specification. When the technical features in different embodiments are shown in the same drawing, it can be regarded that the drawing also discloses the combination examples of the respective embodiments involved.

[0042] The above-described embodiments only represent several implementation manners of the present application. The description is relatively specific and detailed, but it should not be construed as a limitation on the scope of the patent application. It should be noted that for those of ordinary skill in the art, without departing from the concept of the present application, several modifications and improvements can still be made, and these all belong to the protection scope of the present application.
