Nitrogen machine in the purchase of air compressor, in addition to the purchase cost, how to save the high cost of electricity? How to prolong the life of air compressor? How to smooth supply pressure? And how to reduce environmental noise and pollution? Users are also concerned about the problem, how to choose the right key factors in the early purchase of air compressor. When selecting air compressor, we must know the following points:
1, the use of compressed air
2. Minimum working pressure and the amount of compressed air required per minute;
3, the tip and off peak demand. If the pressure difference between the highest and lowest with 3bar, we must consider the high and low voltage shunt, then according to the load change from the peak of the tip, to choose different models of air compressor, such as base load centrifugal or spiral; load changes with high pressure air and large storage barrels to match;
4, according to the different quality of the gas with the selection and configuration of different forms and grades of the dryer and precision filters, too good quality waste of energy, the quality of the impact of production, must be carefully considered;
5, air compressor control technology change rapidly, "Multi Chain" and "variable speed" and "remote control" technology, can effectively inhibit the no-load waste BOV and spiral centrifugal the (save electricity 25-40%), reduce the standby capacity and investment (15-30%), stable pressure (minus 0.1bar);
6 horsepower and air volume and efficiency not only is marked on the nameplate, the focus is the actual performance curve and per horsepower wind;
7, to consider the installation room space size, ventilation, noise, waste heat and waste water recycling and other effects of the use of energy. In addition, the centralized distribution than the lower installation, maintenance and control costs, but also can reduce peripheral equipment;
8, as for cooling with air cooled and water cooled air-cooled two, without additional investment in cooling tower and water, but must have good ventilation; cooling operation temperature is not affected by the environment, there is bad press in life, but there are shortcomings and obstruction of the icy burst;
9, power supply planning, voltage demand and voltage stability of the voltage drop must be required, the centrifuge is usually high voltage, can not move, the start of the power grid will cause impact, should maintain regular operation;
10, the maintenance of the computer room to have the appropriate maintenance space and the necessary lifting facilities and access, engineering personnel and maintenance should also carry out different maintenance professional training.
