What is the difference between power frequency screw air compressor and permanent magnet variable frequency screw air compressor?
In general screw air compressors, the number of revolutions of the rotor with power frequency is as much as it is. The frequency conversion air compressor can adjust the number of revolutions according to the required air volume. The empty load rate is greatly reduced, saving energy and electricity.
The permanent magnet has no motor bearing, its power transmission is simpler and the loss is lower, so it saves about ~ 7% energy than the ordinary frequency converter. Price permanent magnet frequency conversion> frequency conversion> power frequency.
1) Life is different.
From the perspective of the service life of the machine, the permanent magnet variable frequency screw air compressor is better. Due to the use of inverter drive, therefore, the air compressor in the start, the use of "soft start", for the motor has a certain protective effect, reduce the possibility of burning the motor.
2. The parts are different.
From the perspective of parts, the permanent magnet variable frequency air compressor adopts high-efficiency rare earth permanent magnet motor and frequency converter. These two components are of great help to the energy saving of air compressor.
3, maintenance costs are different.
From the perspective of maintenance cost, the permanent magnet motor does not need bearings, does not need to add grease, eliminates the point of failure and reduces maintenance costs.

maintenance
1, daily check the oil level, exhaust temperature and exhaust pressure, check whether there is abnormal sound;
2. Open the drain valve of the separator to discharge condensate before starting up every week, check whether there is leakage everywhere, check the safety valve, and check the belt wear (visual inspection);
3. Regularly check the intake control valve, minimum pressure valve, electric control box connection terminal, safety valve and cooling fan;
4, regular cleaning, cleaning the cooler, test the reliability of the safety valve;
5. Regularly replace the oil filter element, oil separator element, air intake filter element and lubricating oil.

The water lubricated air compressor produced by Shanghai granklin group is widely used in metallurgy, machinery manufacturing, mining, electric power, textile, petrochemical, textile and other industries. Our cases cover all provinces and cities in China. Oil-free screw air compressor
View detailsWhen used as a process source gas, compressed air is in direct contact with materials and food. When used as a power source, although not in direct contact with food and raw materials, but most of them are used in clean areas. Therefore, compressed air for food must use clean compressed air.
What are the advantages of a long-tested market-tested "water-lubricated air compressor"? It is necessary to explain in detail that water-lubricated air compressor, products such as "air compressor head" use water instead of traditional lubricating oil to lubricate the air compressor head.
Water lubricated single screw air compressor is an oil-free air compressor series, which uses water as the lubricating medium, which fundamentally solves the problem of environmental pollution caused by lubricating oil. Compared with other oil-free air compressors, it has a simple and compact structure; low speed, vibration and noise
Domestic oil-free air compressor manufacturers, choose "Shanghai Granklin Group", a group company specializing in the production of "water-lubricated air compressors. Years of "oil-free air compressor" production, has accumulated rich experience and profound technology, in the country has a wealth of cases. There are pharmaceutical factory, food factory, electronics factory, process gas factory (such as argon), laboratory preparation, marine air compressor, bottle blowing, beverage, wine, hospital and so on.
Oil-free air compressor rubber ring can wipe the oil? This question granklin group's Shen for you to answer, oil-free air compressor is naturally not allowed to appear in the presence of lubricating oil in the accessories. Why can't oil-free air compressors have oil?
Common types of oil-free compressor are: oil-free scroll air compressor, dry oil-free air compressor, water lubrication oil-free air compressor. Different oil-free screw air compressor models, exhaust pressure, power and exhaust volume parameters are different. The medical water-lubricated air compressor produced by Shanghai Granklin Group is 100% oil-free.
View detailsGranklin water lubricated oil-free air compressor, through water lubrication, air compressor head operation process, do not need lubricating oil. Compressed air does not contain oil, in order to meet the modern, large-scale safety production.
Shenzhen air compressor factory direct sales, Shenzhen what factory in the air compressor machine at low temperature and at room temperature, the service life of the oil filter is not the same, low temperature models will greatly slow down the carbonization of filter paper, prolong the invalid use of filter paper time; In addition, poor filter paper is invalid.
The water-lubricated air compressor produced by Shanghai Granklin Group is simpler and more labor-saving than the traditional oil-injected screw air compressor. The gas production of single screw air compressor is lower than that of twin screw air compressor in energy consumption. Basic maintenance In order to enable the air compressor to operate normally and reliably and ensure the service life of the unit, a detailed maintenance plan must be formulated, and the fixed person operation, regular maintenance, and regular inspection and maintenance must be carried out to keep the air compressor unit clean, oil-free and free.
