Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of air compressors, in particular to an energy-saving and consumption-reducing air compressor. Background Art
[0002] It is well known that the energy consumption of bottle blowing machines accounts for about half of the energy consumption of the production line, and the energy consumption of high-pressure air compressors accounts for more than half of the energy consumption of bottle blowing machines. The energy efficiency of high-pressure air compressors largely affects the energy efficiency indicators of the entire production line. Variable frequency high-pressure air compressors have been widely used in the industry. They generally use induction motors to drive the compressor host through belt transmission. The unloading loss is reduced through variable speed adjustment, which saves a lot of energy for users in the industry.
[0003] The existing referenceable Chinese utility model patent has a publication number of CN219081797U, which discloses a stable air compressor and relates to the field of air compressor shock absorption technology. The utility model includes a base and an air compressor body, a support plate is installed on the upper surface of the base, a buffer seat is fixedly connected to the bottom surface of the support plate, the buffer seat and the base are slidably matched, the air compressor body is installed above the support plate, a connecting plate is fixedly connected to the bottom surface of the buffer seat, a number of spring shock absorbers are installed between the connecting plate and the base, an installation groove is provided on the upper surface of the support plate, a fan is installed inside the installation groove, and a ventilation groove is provided on one side wall of the buffer seat. The utility model provides good stability to the bottom of the air compressor by arranging a buffer seat and a spring shock absorber, effectively alleviates the wear of the air compressor body caused by the vibration of the air compressor, and improves the life of the body.
[0004] Based on the search of the above patents and in combination with the equipment in the prior art, it is found that the efficiency of the induction motor will drop sharply as the speed decreases, especially when the speed is lower than 50%, the motor efficiency is often less than 90%. Therefore, most manufacturers will set the lower limit of the frequency conversion range to more than 60%. This will cause unloading losses due to the fact that the frequency conversion range of the air compressor cannot fully meet the changing needs of the system's gas consumption. At the same time, the existence of these problems such as low belt transmission efficiency and large transmission losses affects the use of the device. Utility Model Content

At the same time, due to the advantages of low belt transmission efficiency and large transmission losses, the above-mentioned technical problems are solved.

In this way, the frequency conversion range of the air compressor cannot fully meet the changing demand of the system gas consumption, resulting in unloading loss. At the same time, due to the low efficiency of the belt transmission, the transmission loss is large. BRIEF DESCRIPTION OF THE DRAWINGS
