What is the difference between a fixed screw air compressor and a variable frequency screw air compressor?
Most of the variable frequency air compressors are also fixed, and the fixed screw air compressors include variable frequency air compressors and water lubricated air compressors produced by Granklin Group are also fixed.
The common one is the one-piece screw air compressor. The one-piece screw air compressor is small in size. It integrates the air compressor, the air storage tank, the cold dryer and the filter into a whole.
where the fixed screw air compressor reflects its advantages, the use of air compressor greatly facilitates our industrial production. With the progress of technology, the screw air compressor has gradually replaced the traditional piston compressor.
I don't know if you know about the fixed screw air compressor. As a popular air compressor, the advantages of the screw air compressor are also remarkable. Let's take a look at it. Product specifications are relatively easy. In a certain air volume range, the diameter and shape of the rotor can be maintained unchanged, and only the screw rotor needs to be lengthened and shortened to meet the needs of different air volumes. This feature can reduce manufacturing costs to help market competitiveness.
Now the new control mode for the use of permanent magnet motor dedicated variable frequency drive control mode, with high efficiency and always can be maintained at a very high level, any speed of constant torque operation, speed stability, speed change response speed (from 0 to rated speed acceleration time is less than 50ms, and there is no impact current), low noise advantages.
When 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.
According to the industry to choose oil-free air compressor, not only to consider the air compressor, air compression station investment, operating costs, operating costs and other comprehensive technical and economic indicators, but also to consider whether the air compressor in line with environmental protection, stable and reliable, excellent production quality of the original
For the screw air compressor should be how to select, you first need to know the work flow of the screw air compressor, and then determine how to select. Generally speaking, there are three steps:(1) first determine the working pressure;(2) then set the corresponding volume flow;(3) finally, the power supply capacity. Selection of working pressure (exhaust pressure):
Frequency conversion air compressor is made for energy saving. General production includes permanent magnet frequency conversion and ordinary frequency conversion. In the world of variable frequency air compressors, the most energy-saving is the permanent magnet variable frequency air compressor. Energy saving is only relatively speaking, its ultimate goal is to save money
Oil-free air compressor has the characteristics of energy saving, environmental protection, stable and easy to use. In the maintenance of consumables and other above can save a lot of money for the enterprise, choose Shanghai granklin group of water lubricated air compressor is the right decision.
View detailsNo matter what to buy, we are more valued brand, but so many brands of air compressor, how to pick out good quality in so many brands of air compressor, oil free air compressor at a reasonable price. The average person has three choices.
In an increasingly competitive industry, customers are often misled by lower air compressor prices and buy an air compressor with low price but poor quality. Here is a brief introduction to the relevant knowledge about the price of air compressor.
View detailsAs a manufacturer of water-lubricated air compressors, granklin group has always tried its best to meet the needs of users. in the three series of power frequency air compressors, frequency conversion air compressors and permanent magnet frequency conversion air compressors, why do water-lubricated air compressors seldom make power frequency series? This is to start with the stratification of screw air compressors. The largest use of screw air compressors is the oil screw air compressor that needs to be filled with lubricating oil. However, because the gas contains oil, it cannot be used in some industries that require higher gas.
View details1. The compressed air produced by oil-free air compressor is oil-free. With the improvement of users' requirements for the quality of compressed air source, oil-free air compressor is more and more widely used in some industries with high requirements for the quality of compressed air source. Although in
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.
