Description

A star-shaped scroll compressor

technical field

The utility model belongs to the field of scroll compressors, in particular to a star-shaped scroll compressor, which can be applied to the fields of machinery industry, chemical industry, medical treatment, food, energy, transportation and aerospace.

Background technique

The scroll compressor is a new type of compressor developed and applied in the 1970s in the world. Although the scroll compressor was invented as early as 1905, it was actually put into use in the 1980s. Especially in the past 10 years, it has been successfully applied to air-conditioning, refrigeration and heat pump systems abroad, and has shown superior and unique performance compared to other types of compressors, which has attracted great attention from various countries. , high reliability, low energy consumption, low noise, few parts, compact structure and other outstanding advantages have attracted the attention of many countries, and it is called a new generation of compressors. Compared with the reciprocating compressor with the same capacity, the volume is 40% smaller, the weight is 15% lighter, the number of parts is reduced by 85%, the efficiency is increased by 10%, and the range of torque variation is reduced by 90%.

How to save energy, protect the environment and improve efficiency has become an important factor in the development of compressors. Under some specific environmental requirements, oil-containing scroll compressors have been unable to meet the use requirements. With the development of the times and the advancement of science and technology, through extensive and in-depth research by scientific researchers, the oil-free scroll compressor has finally come out. Oil-free scroll compressors not only have all the advantages of oil-containing compressors, but also completely get rid of the compressor's dependence on lubricating oil. Since then, scroll compressors can be divided into oil-containing, micro-oil, and oil-free scroll compressors, and oil-free scroll compressors and oil-containing scroll compressors have incomparable characteristics:

1. The oil-free scroll compressor can provide absolutely oil-free compressed air.

2. The oil-free scroll compressor completely gets rid of the dependence on lubricating oil, which is energy-saving and environment-friendly.

How to manufacture a high-efficiency large-displacement oil-free scroll compressor has become a top priority in the development of oil-free scroll compressors. At present, most of the existing scroll compressors use a motor directly connected to a compressor head or a motor connected to a compressor head through a belt drive, or a combination of multiple such structures to form a large-displacement compressor , the above method has inevitable disadvantages:

1. The large-displacement scroll compressor is composed of multiple sets of one motor directly connected to one compressor head or one motor connected to one compressor head through belt transmission, which wastes energy and increases The noise and volume are increased, and it cannot be applied in some places with strict requirements on volume.

2. In many occasions that require large displacement and high power, due to the limitations of the above structure, it cannot be used.

3. When there is no power supply in mines, ships and road construction, and the motor cannot be used as power, the scope of use of scroll compressors is limited.

4. Each compressor head needs to be equipped with a motor, which virtually increases the manufacturing cost.

Utility model content:

In order to solve the above technical problems, the utility model provides a scroll compressor with a star structure. Two or more compressor heads are arranged on the star structure of the compressor, and the main shaft of the corresponding pulley is provided. , to achieve a motor directly connected to multiple compressor heads or a motor connected to multiple compressor heads through a belt drive.

The technical scheme of the utility model is:

A scroll compressor with a star structure, the compressor includes a compressor head, a star structure frame, a coupling, a pulley, and a main shaft, and the star structure frame is a star structure Two or more compressor head fixing seats are evenly distributed on the frame circumference, and a compressor head is fixed in each compressor head fixing seat on the frame of the star-shaped structure. The shaft extension end of the head is provided with a pulley, the main shaft is fixed at the center of the star-shaped structure frame, and one end of the main shaft is provided with a multi-groove pulley, and the pulley of the compressor head is connected with the multi-groove pulley of the main shaft through a belt. The pulley of the main shaft is a multi-groove pulley, and the pulley of each scroll compressor head is connected to the pulley of the main shaft in a staggered manner, and the other end of the main shaft is connected with the motor or the engine through a pulley or a coupling.

In the star-shaped scroll compressor described above, when there are two compressor head fixing seats, they are arranged in a two-pointed star shape; when there are three compressor head fixing seats, they are arranged in a star shape. Arranged in a triangular star shape. When there are four compressor head fixing seats, they are arranged in a four-pointed star shape. When there are more than five compressor head fixing seats, they are arranged in a polygonal star shape.

In the scroll compressor with a star structure, when the other end of the main shaft is connected to the motor or the engine via a pulley, the motor or the engine is set on the same side as the frame of the star structure, and the other end of the main shaft is connected to the motor Or when the engine is connected through a coupling, the motor or engine is arranged outside the frame of the star structure.

Said scroll compressor with a star structure, said compressor is a scroll compressor.

Advantage and effect of the present utility model:

1. Compared with the existing structural method in which multiple motors are directly connected to a compressor head or a motor is connected to a compressor head through a belt drive, the noise, volume and manufacturing cost are greatly reduced.

2. Compared with the existing large-flow scroll compressor structure, this utility model can use other power equipment except the motor as power, such as: engine, etc., which solves the need for a large amount of compression when the motor cannot be used gas problem.

3. Compared with the structure of the existing large-flow scroll compressor, the utility model only uses one motor (or engine) as the power, which reduces the production cost.

4. Realize the concentrated supply of large-flow compressed gas with a scientific structure, reduce the volume and cost of the scroll compressor, and change the situation that the scroll compressor only relies on the motor as power.
