Description

Technical Field

[0001] The utility model relates to the technical field of air compressors, in particular to a high-efficiency double-head air compressor. Background Art

[0002] An air compressor is the main body in an air source device, which is a device that converts the mechanical energy of a prime mover (usually an electric motor) into gas pressure energy. It is mainly used to compress air and provide the required high-pressure gas for other equipment. Therefore, it has a wide range of applications in many industrial and manufacturing fields, such as painting spraying and drilling operations in the automobile manufacturing process.

[0003] A double-head air compressor is a special air compressor, which is characterized in that two compressor heads are equipped on one body. Each compressor head has a compression chamber and a cylinder. Therefore, the double-head compressor has two compression chambers and two cylinders. This design enables the double-head compressor to complete work more efficiently. The working principle of the double-head compressor is that when the piston of the first compressor moves downward, the gas is inhaled into the cylinder. Once the piston reaches the lower limit, it starts to move upward, compresses the gas and discharges it into the shared air cylinder. Then, the second compressor starts to move downward, inhales the gas into the second cylinder, compresses the gas again and discharges it into the shared air cylinder. As the two compressors continuously cycle, high-pressure compressed air is finally sent out through the air outlet.

[0004] An air filter element is usually arranged at the air inlet of a common double-head air compressor to prevent impurities in the air from entering the interior of the air compressor. A filter screen is usually arranged outside the air filter element to block larger impurities such as mosquitoes in the air. However, the filter screen is easily blocked, resulting in a reduction in the air intake volume and a decrease in the working efficiency of the double-head air compressor. In view of this, this application proposes a high-efficiency double-head air compressor. Content of the Utility Model

[0010] Furthermore, an internally threaded pipe is fixedly mounted on the top of the mounting plate, the mounting top cover is threadedly mounted inside the internally threaded pipe, and filter holes are formed in the surface of the mounting top cover.

[0011] Furthermore, a turntable is fixedly mounted at the top end of the rotating shaft located above the mounting top cover, and a handle is rotatably mounted on the top of the turntable.

[0017] The high-efficiency double-headed air compressor solves the problem that the filter screen outside the air filter element is easily blocked, resulting in a reduction in the intake air volume and a decrease in the working efficiency of the double-headed air compressor. This is achieved by setting a filter base at the top of the noise reduction housing, an installation top cover at the top of the filter base, and a filter screen cleaning component inside the installation top cover.
