Description
Technical field
The utility model relates to a kind of single screw compressors with second vapor injection function.
Background technique
Semi-enclosed single screw compressor, main motion parts are that main rotor and the star-wheel being arranged symmetrically in two sides turn
Dynamic component, belongs to positive displacement compressor.In order to improve the compressed capability of gas, gas supplementary structure can be generally added on the compressor,
To solve compressor excessive discharge temperature and the problems such as insufficient heating capacity under worst cold case;But traditional gas supplementary structure
Air compensation it is smaller, influence the effect of Gas-supplying enthalpy-increasing.
Utility model content
The purpose of this utility model is to provide a kind of single screw compressor with second vapor injection function, structure is closed
Reason, can effectively increase air compensation, to promote the effect of Gas-supplying enthalpy-increasing;Also, by being mended from the bilateral of compressor
Gas, so that the uniform force of screw rod in the process of running, is conducive to the stable operation of compressor.
To achieve the above object, the technical solution of the utility model is to design a kind of single screw rod with second vapor injection function
Compressor, including casing are equipped with the Meshing Pair an of screw rod and two planar gaterotors compositions being arranged symmetrically, institute in the casing
It states casing and is equipped with the first gas supplementing opening and the second gas supplementing opening being connected to its inner cavity, first gas supplementing opening and the second gas supplementing opening difference
Positioned at the radially opposite sides of screw rod, first gas supplementing opening is connected with the first blowdown pipe, which is equipped with towards first
First check valve of gas supplementing opening, second gas supplementing opening are connected with the second blowdown pipe, which is equipped with towards second
The second one-way valve of gas supplementing opening.
Preferably, the shape of first gas supplementing opening and the second gas supplementing opening is circle.
Preferably, the axis of the axis and the second gas supplementing opening of first gas supplementing opening coincides.
Preferably, the casing outer wall is equipped with several vertical bar shaped reinforcing ribs, and several vertical bar shaped reinforcing ribs are along casing
Circumferential setting, and single vertical bar shaped reinforcing rib is arranged along the axial direction of casing.
Advantages and beneficial effects of the utility model lie in that by the first blowdown pipe and the second blowdown pipe simultaneously in casing
Compression chamber carry out tonifying Qi and to increase air compensation promote the effect of Gas-supplying enthalpy-increasing.Also, the first gas supplementing opening and the second tonifying Qi
Mouth is located at the radially opposite sides of screw rod, and during tonifying Qi, the uniform force of screw rod is conducive to the stable operation of compressor.
In addition, can effectively improve the intensity of casing by the way that vertical bar shaped reinforcing rib is arranged on the outer wall of casing.
Detailed description of the invention
Fig. 1 is the schematic diagram of the utility model.
Specific embodiment
With reference to the accompanying drawings and examples, specific embodiment of the present utility model is further described.Implement below
Example is only used for clearly illustrating the technical solution of the utility model, and cannot be used as a limitation the protection model of limitation the utility model
It encloses.
The technical solution of the utility model specific implementation is:
As shown in Figure 1, a kind of single screw compressor with second vapor injection function, including casing 1, the interior installation of the casing 1
The Meshing Pair being made of a screw rod and two planar gaterotors being arranged symmetrically, the casing 1 are equipped with and are connected to its inner cavity
First gas supplementing opening 2 and the second gas supplementing opening 3, first gas supplementing opening 2 and the second gas supplementing opening 3 are located at the radially opposite sides of screw rod, institute
It states the first gas supplementing opening 2 and is connected with the first blowdown pipe 4, which is equipped with the first check valve towards the first gas supplementing opening 2
5, second gas supplementing opening 3 is connected with the second blowdown pipe 6, which is equipped with the second list towards the second gas supplementing opening 3
To valve 7.
The shape of above-mentioned first gas supplementing opening 2 and the second gas supplementing opening 3 is circle.
The axis of above-mentioned first gas supplementing opening 2 and the axis of the second gas supplementing opening 3 coincide.
1 outer wall of said machine casing is equipped with several vertical bar shaped reinforcing ribs, which sets along the circumferential direction of casing 1
It sets, and single vertical bar shaped reinforcing rib is along the axial direction setting of casing 1.
Advantages and beneficial effects of the utility model lie in that by the first blowdown pipe 4 and the second blowdown pipe 6 simultaneously to casing
Compression chamber in 1 carries out tonifying Qi and promotes the effect of Gas-supplying enthalpy-increasing to increase air compensation.Also, the first gas supplementing opening 2 and second
Gas supplementing opening 3 is located at the radially opposite sides of screw rod, and during tonifying Qi, the uniform force of screw rod is conducive to the stabilization of compressor
Operation.In addition, can effectively improve the intensity of casing 1 by the way that vertical bar shaped reinforcing rib is arranged on the outer wall of casing 1.
The above is only the preferred embodiment of the utility model, it is noted that for the common skill of the art
For art personnel, without deviating from the technical principle of the utility model, several improvements and modifications can also be made, these change
It also should be regarded as the protection scope of the utility model into retouching.
