When purchasing screw air compressors, we often pay more attention to whether the air compressors are free of oil after compressing the gas. It is not cost-effective to consider selecting some power frequency air compressors based on the principle of cost saving. We should not only consider the oil-free air compressors but also consider energy saving. Then the most suitable air compressor is water-lubricated air compressors. The air discharged by water-lubricated air compressors does not contain oil, which is the first choice for purchasing oil-free air compressors.
The water-lubricated air compressor produced by Shanghai Granklin Group is a screw-type air compressor, which is very consistent with the characteristics of stable gas supply and oil-free gas. In terms of energy saving, we can also choose water-lubricated permanent magnet variable frequency air compressor, which fully meets the needs of both oil-free and environmental protection and energy saving.
water-lubricated oil-free air compressor is one of the compressors. Its compression medium is air, and the compressor can be used to compress many things, not just air. The difference between water-lubricated oil-free air compressors and ordinary compressors, water-lubricated oil-free air compressors can be applied to some more special environments, such as food processing, textiles, chemicals, air separation, process gases, etc.
When many customers buy permanent magnet variable frequency screw air compressors, they all say that they hear that permanent magnet variable frequency screw air compressors are very energy-saving. How energy-saving is the permanent magnet variable frequency screw air compressor?
How much energy can permanent magnet variable frequency screw air compressor save than general air compressor.
Take the GW132VW water-lubricated permanent magnet frequency conversion screw machine produced by Shanghai Graclin Group as an example:
(132KW,8bar, displacement range: 6.75~22.52m & sup3;/min)
1. Frequency conversion constant pressure output of compressed air. If the outlet pressure level of compressed air is required to be 6bar, we can set the constant pressure to be 6bar, and adjust the operating frequency according to the customer's air demand to achieve the purpose of adjusting the operating power. Oil-free piston compressors need to set the pressure level to be 6 ~ 8bar, the pressure difference is at least about 2bar, and the pressure difference of 2kg requires more than 15% of electricity charge;
2. Permanent magnet frequency conversion technology can realize no unloading. Generally, ordinary compressors will have pressure fluctuation unloading. This part can be saved and generally accounts for about 13% to 15% of the total energy consumption;
3. Permanent magnet frequency conversion technology has no starting impact on the power grid, saving part of power consumption;
4, water lubrication oil-free screw machine almost no displacement attenuation can save part of the power consumption;
to sum up, it is theoretically calculated that the water-lubricated oil-free screw machine saves more than 30% of electricity compared with the oil-free piston air compressor. We calculate according to the actual electricity saving of 15%, running 24 hours a day and working 300 days a year: 15% X132X24X300 = 142560KWH
What is the difference between the power frequency screw air compressor and the permanent magnet variable frequency screw air compressor? The general screw air compressor when the power frequency of the rotor is how much is how much, the frequency of the air compressor can be adjusted according to the required air volume The number of revolutions is greatly reduced, saving energy and electricity.
In the compressed air industry, one of the most important developments is the use of oil-filled and oil-free air compressors. Each has advantages, depending on the application. Both are major markets. A key difference is that oil-free compressors are not as easy as oil-injected compressors.
The normal operation of the factory is inseparable from the stability of the equipment, and the stability of the equipment is not only related to its performance, but also inseparable from the daily cleaning and maintenance. Correct maintenance steps can not only keep the equipment in good performance but also improve the product yield, but also
What are the forms of oil-free air compressors? At present, oil-free air compressors are widely used. What are the forms of oil-free air compressors? First: Water-lubricated screw Water-lubricated oil-free air compressors use pure water. Therefore, their equipment is sealed during operation,
Choose Shanghai Granklin Group to purchase air compressors, whether it is price or service, do not lose imported screw air compressors. As for the price of an air compressor, the things involved are also in all aspects. Price is an important reference standard, but it is not the only weighing standard. We will definitely get good results under a telephone consultation.
View detailsAccording to market conditions, most manufacturing industries choose air compressors. For example, oil-free air compressors are generally used in the food industry and the pharmaceutical industry. The laser industry uses more medium pressure. Textile and chemical fiber industry uses more low pressure. For high-pressure testing of products, bottle blowing
Oil-free air compressors can be divided into two categories from the perspective of lubrication: self-lubricating oil-free air compressors and water-lubricated oil-free air compressors. These two air compressors have both advantages and disadvantages, and there is no conclusion as to who is good or bad. Oil-free water lubrication air compressors are generally screw air compressors, the main
The water-lubricated oil-free air compressor has the characteristics of energy saving, environmental protection, stability and durability. It has been widely used in many industries, and the maintenance and maintenance of oil-free air compressors are also concerned by users. The correct daily maintenance and use, can be extended.
When it comes to medicine, everyone should be familiar with it. However, most people are not very clear about the production process of drugs. Screw air compressors are often used in the production of drugs. So what role does the air compressor play in the pharmaceutical industry?
The single screw water lubricated air compressor uses pure water for lubrication and cooling, and the internal parts combination of the body is made of special material medical grade stainless steel, which will never corrode. Dry oil-free air compressor still depends on lubricating oil to cool, the body will produce oil smell.
