Energy saver system for air compressor

Abstract

The invention relates to an energy saver system for an air compressor, which comprises a PLC (programmable logic controller), an air compressor and a pipe network system matched with the air compressor. In the air compressor, a compressor is connected with a motor; oil and gas are separated by an oil-gas separator connected with the compressor, and then gas is supplied to the pipe network system by a radiator; and the air compressor is driven by the PLC. The energy saver system for the air compressor also comprises a soft starter and a thermostat, wherein the thermostat is arranged on an oil return pipeline, so that when motor oil is reflowed into the compressor, the temperature of the air compressor is kept wet. The soft starter is arranged on the air compressor to realize the fast start of the soft starter. The pipe network system comprises a gas cylinder, a drier and an air filter. The gas cylinder and the drier are arranged in the user side of the pipe network system, and are connected with the air filter. The gas supply end of the pipe network system is connected with the air compressor so that the pressure difference before and after air is compressed can be raised and fallen within 0.5bar. With the adoption of the energy saver system for the air compressor, the resistance to the pipe network is effectively reduced, the running load of the air compressor is lowered, the air compressor can start or stop rapidly, the impact to the power grid is mitigated, and the service life of the air compressor is prolonged.

Description

technical field [0001] The invention relates to an air compressor energy-saving device system, which improves the shortcomings of screw air compressors with zero unloading work, inability to start and stop quickly, and long running time of the heat engine, reduces the impact on the power grid, reduces harmonics, protects the air compressor and protects the Extend the life of the unit. technical background [0002] With the continuous development of automation, more and more companies in various regions of the world are using air compressors and increasing the capacity of air compressors. Due to the obvious energy efficiency of the screw micro-oil air compressor, it has been used by the majority of users, but the current energy consumption of the air compressor generally accounts for 15% to 35% of the electricity consumption of the enterprise, and the operating cost is high. There are also many companies that have purchased frequency converters for energy-saving transformati...
