How to Better Save Electricity by Air Compressor

The selection of air compressor equipment requires high-efficiency compressors. In view of the gas consumption in enterprise production, the use of gas during peak and trough periods needs to be considered. Variable working conditions can be adopted and permanent magnet frequency conversion screw air compressor can be adopted, which is beneficial to energy saving.

At present, the permanent magnet motor of the domestic permanent magnet frequency conversion screw air compressor is more than 10% energy-saving than the general motor, has the advantages of constant pressure air, does not cause waste of pressure difference, uses how much air to blow, does not need to add and unload, etc. More than 30% energy saving than ordinary air compressor. Frequency conversion production gas is especially suitable for modern production and manufacturing. Centrifuge units can also be used for units with large gas consumption, so that large flow can alleviate the problem of insufficient peak gas consumption.

Screw air compressor

the main rotor diameter is large, and the auxiliary rotor diameter is small. The teeth form a spiral and the two mesh with each other. The two ends of the main and auxiliary rotors are respectively supported and positioned by bearings. When working, the motor directly takes the main rotor through the coupling (or belt). Because the two rotors mesh with each other, the main rotor directly drives the auxiliary rotor to rotate together. The coolant is directly sprayed into the meshing part of the rotor from the nozzle at the lower part of the compressor casing, and mixed with air to take away the heat generated by compression to achieve the cooling effect. At the same time, a liquid film is formed to prevent direct contact between metal and metal between rotors and to close the gap between rotors and housings. The injected coolant can also reduce the noise generated by high-speed compression.

Since users want to save money, we should persuade them along the way of saving money. Everyone does not know whether to pay attention to overcurrent when maintaining the machine. Generally, the current difference before and after maintenance will be 5 ~ 15%(7 ~ 10% is the mainstream). This means that the electricity wasted by delaying maintenance for 500 hours is enough for one maintenance, and the longer the delay, the greater the difference in current. This is because the air compressor has been operated after a round of maintenance cycle, and a lot of dust and carbon deposits have been adsorbed on the oil surface. If the maintenance is postponed, the dust and carbon deposits on the oil surface will increase. In addition, after a round of maintenance cycle operation, the aging speed of lubricating oil will be accelerated, and the speed of carbon deposition will be geometrically doubled. In addition, if the air filter is not replaced in time after a round of maintenance cycle operation, the suction resistance will become larger and larger, which will also reduce the energy efficiency of the air compressor.
