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.
Business owners were confused about the choice of screw air compressor products in the early stage of factory construction, because during the factory construction process, they will definitely receive sample books from various manufacturers sent by many sales staff. Screw air compressor sales staff publicity
Frequency conversion air compressor power saving? To ask whether the frequency conversion air compressor saves electricity, but also depends on the machine structure and product quality of the air compressor manufacturer. The same screw air compressor, the difference between different manufacturers is still very big. Starting from the parts used in the products, small factories pay more attention to the price, take the low price route to do the market, and earn some maintenance costs by replacing parts after sales.
View detailsCommon 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 detailsIt depends on your application scenarios, such as medical, chemical, food, electronics, and other industries that require higher gas requirements, then the "5 cubic screw air compressor price" and ordinary "5 cubic screw air compressor price" is very different. So what is the difference between a high standard "screw air compressor" and an ordinary "screw air compressor?
The application industries of water-lubricated air compressors produced by Shanghai Granklin Group: university laboratories, chromatographic analysis, medical pharmacy, dentistry, food processing, construction engineering, chemical industry, machinery, environmental protection, meteorology, hydropower, spraying, sandblasting, PET Bottle blowing, leak detection, metallurgy, water treatment, printing, shipping, textile, petrochemical, electronics, instrumentation, tobacco, nitrogen production.
Q: What is the difference between a cold dryer and a suction dryer? A: The working mode of a cold dryer is different from that of a suction dryer. The cold dryer condenses the moisture in the air by lowering the air temperature to obtain dry compressed air.
What should I pay attention to when the permanent magnet frequency conversion oil-free air compressor is turned on in summer? At this time, people are afraid of heat. We need to stay in the air-conditioned room blowing the air conditioner and drinking iced drinks. High temperature weather is not only a test for people, but also a frequent failure stage for oil-free air compressors. The most common high temperature phenomenon in summer will cause various failure problems of oil-free air compressor.
The main features of the water lubricated screw air compressor are: reasonable structure, ideal force balance; no radial and axial force during operation, only rotational force. Single-stage compression ratio is high, the shape of the structure size is small: high speed light load, easy to establish hydrodynamic lubrication.
Bearing lubrication method of oil-free and water-lubricated air compressor: 1. Oil-free and water-free air compressor mainly uses water to replace oil, realizing the four major effects of lubrication, cooling, sealing and noise reduction, providing high-quality oil-free air, no pollution and no special treatment for discharged water, which meets the requirements
Features of water-lubricated oil-free screw air compressor: completely oil-free air quality water replaces oil, realizing the four major effects of lubrication, cooling, sealing and noise reduction, providing high-quality 100 oil-free air without pollution, discharging water without special treatment, and meeting environmental protection requirements.
