When buying air compressor, except for acquisition costs, how to save the high electricity costs? How to prolong the life of the compressor? How stable gas supply pressure? And how to reduce ambient noise and pollution? Is also an issue of concern to the user, and how In the initial purchase of the correct choice of compressor plays a key factor. First, you must understand the selection of air compressors the following: 1. The use of compressed air 2, the minimum working pressure and 3, tip and off-peak gas demand required amount of compressed air per minute. If using a pressure difference between the highest and lowest reaches 3bar, it must be considered "high voltage shunt" compressor manufacturer direct, and then tip the burden of change from peak to choose different models of air compressors, such as "baseload" using centrifugal or screw-type (single> 75CMM) (single <60CMM): "Change of load," using high-pressure air machine to cope with the large storage barrels. 4, depending on the air quality with the selection and configuration of different forms and levels of precision filter dryer and, over a good quality waste energy, the impact of insufficient quality manufacturing process, must be carefully considered. 5, air machine control technology advances, "multi-unit chain", "Frequency shift" and "remote monitoring" and other technology, can effectively inhibit the BOV and centrifugal load spiral waste (save electricity 25-40%), reduce backup machine capacity and investments (15-30%), stable gas supply pressure (positive and negative 0.1bar). 6, the operation efficiency is not only a nominal amount of wind-powered and compare the catalog, focusing on the actual "performance curve" and "air volume per horsepower." 7, consider the size of the installation of floor space, ventilation, noise isolation, waste heat, waste recycling and so lead sound energy use. In addition, "centralized" than "distributed" has lower installation, maintenance and control costs, but also can reduce the peripherals. When we carry out maintenance of the screw compressor, and sometimes it needs to be open, then do not pay attention this time if it is likely to cause damage to their parts, accessories or even lost. So under normal circumstances demolition work is to be performed by experienced technicians, and strictly observe the following points: 1. Remove the radial bearings, mechanical seals or floating ring seal, the rotor should be slightly raised, in order to avoid strain matched parts. 2. Remove the radial bearing, floating ring seal, after the coupling hub, should be installed and floating ring seal bearing journal site, loaded shaft coupling hub cone section bandaged to protect. 3. After the demolition of the radial bearing, non-transfer or shifting of the rotor disk, to prevent seal damage. 4. Remove the bearing, sealing parts and hanging at each rotor must be careful, non-beat and collision parts in order to prevent damage. 5. aperture stop with the sealing surface is prohibited hammer or pry with iron bars (if desired beat or poking, you must pad with a soft metal), with the machined surface to avoid damage. 6. To smooth lifting, attention inside and outside in all directions, up and down, left and right, front and rear, which are accessible. 7. hanging and placing parts to be reasonable compressor manufacturer, bundled have protective measures, safe and stable place to be, when they are not allowed to use any of the impeller rotor support. 8. lifting cylinder must understand, partitions, and other parts of the rotor position and lifting equipment weight, rigging choice should not be less than the diameter of the 10-fold safety factor, rigging and equipment edges, surface contact of the application process skids or soft material good pad. 9. lifting cylinder head should be kept subdivision surface level, or the four corners of the cylinder surface distance between the equal split air compressor manufacturer, wholesale, and not with the guide rod with jam screw air compressor manufacturer, lifting process, should carefully observe all relevant parts of the lower decks, etc. not to follow on from the rotor.
