For medicine, food, semiconductor, chemical industry, fermentation and other industries, oil-free and clean compressed air must be the first choice. Oil-free oil-free screw air compressor, water-lubricated oil-free screw air compressor, oil-free scroll air compressor and oil-free centrifugal air compressor are common oil-free. Today, compare two types of oil-free screw air compressors-dry oil-free and water lubrication.
First:
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.
Second:
the pure water of the water-lubricated air compressor system has been circulating in the system. The system will automatically change the water at a set time to ensure the quality of the water, and the operating temperature of the body is not higher than 50 degrees, so the water is not affected inside the body. And scale problems.
The operating temperature of the dry-type oil-free machine is very high, which exceeds 200 degrees, which directly affects the life of the cooling oil and the bearing.
Third:
the single-screw water-lubricated oil-free machine adopts imported special bearings, so there is no problem with direct water lubrication, high efficiency, low head noise, and few bearing combinations.
Twin-screw air compressors generally use FAG or SKF bearings, which are low-temperature bearings with short service life and high noise, and there are many combinations of double head bearings.
Fourth:
single screw water lubricated air compressor is directly sprayed with pure water in the body. Due to the high specific calorific value of water, the compression chamber is almost in the ideal state of isothermal compression and the compression process with the lowest energy consumption.
Dry-type oil-free cooling oil is about 100 degrees, the temperature of the compression chamber exceeds 200 degrees, and the temperature difference is relatively large, so the energy consumption is relatively high.
Fifth:
single-screw water-lubricated oil-free machine, the body and the motor are directly connected, the speed is low below 3000 rpm, there is no speed-increasing gear, the bearing life is long, and the maintenance cost is low.
The dry-type oil-free machine body needs to add a speed-increasing gear to the middle of the motor, because the speed is higher than 18000 revolutions, the speed-increasing gear needs to be increased, the bearing life is short, and the maintenance cost is high.
Sixth:
the water-lubricated air compressor uses water to cool the lubrication seal, the air quality is guaranteed, and the speed is about 3000 rpm. The temperature is about 55 degrees, and the maintenance cost is low.
The dry twin-screw air compressor uses oil to cool the bearings. The air quality cannot be completely clean and environmentally friendly. The two-stage compression speed reaches about 18000 rpm, which consumes labor and the temperature reaches about 200 degrees. It is unsafe and has high maintenance costs.
In the process of air compressor maintenance, one of the most common faults is the overload of the motor of the air compressor.
When we choose an oil-free water-lubricated air compressor, in addition to conventional parameters such as displacement and power, we generally pay attention to its cooling method. Generally, there are two main cooling methods for an oil-free water-lubricated air compressor: water-cooled and Air-cooled, then these two cooling methods
As we all know, the screw air compressor adopts a pre-set configuration, only a single power connection and compressed air connection, and built-in cooling system, which can greatly simplify the installation work. Its advantage lies in the use of high-capacity compression components, its rotor outer circle speed is low, to achieve a high
What brand of air compressor should you choose for purchasing special air compressor for electroplating? The oil-free screw compressor produced by Shanghai Granklin Group provides pure compressed gas, which can avoid the breeding of bacteria and bacteriophage in the gas. In the electroplating industry, there are some problems in the production process, such as the surface of the coating, burning, cracks and so on. People use stirring to solve such problems, and the stirring needs the support of compressed air.
View detailsWhen the pharmaceutical industry chooses air compressors, it is necessary to consider the air quality. High-quality compressed air brings about the quality and efficiency of the products. Granklin air compressor adhering to the oil-free air, accelerate the domestic air compressor to a more high-end industry and technology to continuously improve the quality of oil-free air.
In terms of energy consumption, frequency conversion air compressor is better than ordinary power frequency air compressor, so under the condition, we must choose the granklin frequency conversion air compressor of energy saving and environmental protection. Frequency conversion air compressor procurement must be based on the user needs of the air pressure and air flow, select the appropriate structure type of frequency conversion air compressor. The variable frequency air compressor has good mechanical properties (low vibration, low noise), good adaptability and stable operation.
10 kilograms of oil free screw air compressor how much does it cost? contact our company's sales staff, shanghai granklin group to provide you with 10 kilograms of oil free screw air compressor price. Air compressor, as the name implies, the so-called air compressor, refers to the air from a low
Air compressor in the mechanical processing industry is very important, can be very efficient to promote the mechanical processing capacity, today to talk about how to choose air compressor in this industry. CNC machine tool is an important tool of modern manufacturing industry, is a kind of high-tech mechatronics
The price of "oil-free air compressor" is the standard that we care about very much when we buy "screw air compressor". No one's money is blown by strong winds. Of course, according to different power and exhaust volume, the price of "oil-free air compressor" will inevitably vary greatly. This problem should be specific in the actual parameters, and colleagues should also consider it comprehensively. The choice of "oil-free air compressor price", which is cheaper without considering other factors, may fall into traps and troubles. Different from other brands.
The main maintenance method of screw air compressor is to replace the three filters and one oil. The main methods are: 1. Air filter element. It needs to be replaced after 1500 hours of work; 2. Lubricating oil filter element. Daily use about 2000 hours need to be replaced; 3, oil and gas
