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
Permanent magnet variable frequency air compressor has always been sought after by industrial enterprises with the characteristics of high efficiency, energy saving and environmental protection, and its energy saving effect is also very considerable. In recent years, more and more air compressors with high energy consumption have been replaced by permanent magnet variable frequency air compressors on the market.
What are the common shortcomings of the screw air compressor?(1) When the screw air compressor is shut down, the air inlet is sprayed outward. When the air compressor suddenly stops and does not open the exhaust valve in time to discharge exhaust gas, the air inlet sprays cooling oil outward. At this time, first check whether the intake valve has defects and cannot be closed normally. Second, check whether the oil cut-off solenoid valve has defects. Assuming it is normal, further check whether the check valve on the main exhaust pipe can be closed in time or completely. If there are defects, it should be removed.
In some special production industries, there are relatively high requirements for the gas discharged from the screw air compressor, especially the textile enterprises and the food industry, which basically require the oil content of the compressed air to be particularly low, and basically do the oil-free compressed air. So when the screw air compressor exhaust with oil failure occurs, how do we solve this problem? Oil and gas separation core appears damaged in the operation of the screw air compressor, oil separation core appears damaged such as damage, perforation phenomenon, then it loses the role of oil and gas separation.

When selecting screw air compressors, we all want to choose brand and good quality machines, so which air compressor is a good product
If you need a water-lubricated oil-free air compressor, please contact us "Shanghai granklin Group" at 13918023456. We have produced oil-free screw air compressor between 5.5KW-250KW power. You are welcome to consult at any time.
Shanghai Granklin Group produces and sells water-lubricated air compressors. The whole machine is made of stainless steel without lubricating oil and uses water as a lubricant. Introduction to the dry oil-free air compressor: The crankcase of the fully oil-free compressor is of a dry structure. The large connecting rod, small holes, and the front and rear main bearings of the crankshaft generally use double-port sealed grease ball bearings.
Types of oil-free air compressors are divided according to whether the compressed air contains oil or not, corresponding to oil-free air compressors or micro-oil air compressors. Oil-free air compressors are distinguished according to different compression forms or different host structures. Several common oil-free air compressors are: oil-free
