Description

Technical Field

[0001] This utility model relates to a series two-stage screw air compressor. Background Technology

[0002] Most existing two-stage screw compressor main units adopt a parallel structure, either horizontally or vertically, with the cooling system placed on the side.

[0003] Most existing two-stage screw compressor main units adopt a parallel structure, either horizontally or vertically, with the cooling system placed on the side. This structure requires more space and is more complex. Utility Model Content

[0004] The main technical problem to be solved by this utility model is to change the layout of the series two-stage screw air compressor so that the horizontal and vertical space of the whole machine is fully utilized, the structure is more compact, and the whole machine occupies a smaller area.

[0005] To solve the above-mentioned technical problems, this utility model provides a series two-stage screw air compressor, including: a machine frame, a two-stage compression host, a transmission group, an oil tank group, a cooling group, a welded pipe group, and a power distribution group;

[0006] The transmission group is a gear drive, and the two-stage compressor main units are connected in series through gear drive; the two-stage compressor main units and the oil tank group are arranged left and right along the width direction of the whole machine frame, and the power distribution group and the oil tank group are arranged front and back along the length direction of the whole machine frame.

[0007] The cooling unit is suspended on the top of the machine frame. The machine frame has air inlets on one side along the length direction and one side along the width direction, and an air outlet is provided on the top of the machine frame corresponding to the position of the cooling unit.

[0008] In a preferred embodiment: the two-stage compressor host and the oil drum group, and the oil drum group and the cooling group are respectively connected through the welded pipe group.

[0009] Compared with the prior art, the technical solution of this utility model has the following beneficial effects:

[0010] This utility model provides a series-connected two-stage screw air compressor, which makes full use of the horizontal and vertical space of the whole machine, making the structure more compact and the overall footprint smaller. The main unit adopts a series structure, reducing the width of the whole machine; the cooler adopts a top-mounted design, making full use of the space above the whole machine.

[0013] Figure 3 This is an external view of the air compressor in a preferred embodiment of the present invention. Detailed Implementation

[0014] To make the technical solution and features of this utility model clearer, the following detailed description of this utility model is provided in conjunction with the accompanying drawings and specific examples. It should be understood that these examples are only for illustrating this utility model and are not intended to limit the scope of this utility model. After reading this utility model, any modifications of this utility model by those skilled in the art in various equivalent forms fall within the scope defined by the appended claims.

[0015] refer to Figure 1-3 This embodiment provides a series two-stage screw air compressor, including: a frame 1, a two-stage compressor 2, a transmission group, an oil tank group 3, a cooling group 4, a welded pipe group 5, and a power distribution group 6;

[0016] The transmission assembly is a gear drive, and the two-stage compressor 2 are connected in series via gear transmission. The two-stage compressor 2 and the oil tank assembly 3 are arranged horizontally along the width direction of the overall frame 1, and the power distribution assembly 6 and the oil tank assembly 3 are arranged front-to-back along the length direction of the overall frame 1. The cooling assembly 4 is suspended from the top of the overall frame 1. The overall frame 1 has air inlets 7 on one side along the length direction and one side along the width direction, and air outlets 8 are provided on the top of the overall frame 1 corresponding to the position of the cooling assembly 4. Furthermore, the two-stage compressor 2 and the oil tank assembly 3, and the oil tank assembly 3 and the cooling assembly 4 are respectively connected by the welded pipe assembly 5.

[0017] The aforementioned series-connected two-stage screw air compressor makes full use of both horizontal and vertical space, resulting in a more compact structure and a smaller footprint. The main unit employs a series structure, reducing the overall width of the machine; the cooler uses a top-mounted design, making full use of the space above the unit.

[0018] It should be noted that this application is an improvement on the layout of the various components inside the air compressor. Therefore, the specific internal structures of the oil drum group 3, cooling group 4, welded pipe group 5 and power distribution group 6 do not need to be described in detail in this application, as the above structures are already clearly described in existing air compressors.

[0019] The above is only one specific embodiment of the present utility model, but the design concept of the present utility model is not limited thereto. Any non-substantial modifications made to the present utility model using this concept shall be deemed as an infringement of the protection scope of the present utility model.
