Water lubricated single screw air compressor is an oil-free air compressor series, which uses water as the lubricating medium, which fundamentally solves the problem of environmental pollution caused by lubricating oil. Compared with other oil-free air compressors, it has the advantages of simple and compact structure; low speed, low vibration and noise; low exhaust temperature, high thermal efficiency; stable and reliable performance, and low specific power. It is the development trend of new oil-free machines.
1. The air compressor without oil and water lubrication is lubricated with water, so is the water content of the discharged air larger than that of other air compressors?
The oil-free water-lubricated air compressor is an isothermal compression method of about 45 degrees, and the condition for producing gaseous water is heated to above 65 degrees, so there is no vapor water. And qualified water-lubricated oil-free screw compressor products, the discharged compressed air is free of liquid water, the water content of water-lubricated oil-free machine is determined by the water vapor separation system, and the water lubrication mentioned above is free of gaseous water, and liquid water can be completely separated by centrifugal cyclone through the separation system. The water content in Ofko oil-free water lubrication air compressor is 15% lower than that of ambient air and lower than that of screw oil injection. Each Ovko oil-free machine will be tested by a professional dew point meter, and the water content will be qualified and up to the standard to be delivered.
2. Does the cabin look like a natural "bacterial ship" without oil and water lubrication? Is the discharged air high in bacteria?
Water can only breed bacteria if it stays in a sealed space for more than 72 hours. The water in the machine without oil and water lubrication is always circulating, and a part of the water is automatically discharged every 200 hours to make up a part of the water. After the cleaning of the water in the air bacteria and dust impurities are a large number of cleaning and through the lubrication of water adsorption and water removal, and the filter in the compressor can filter part of the bacteria, the discharge of compressed air will only contain very few bacteria. Secondly, the water in the cabin will react only when it comes into contact with air. The intake valve and pressure valve are all sealed. The water inside the machine cannot contact with the air at all and has no conditions that may breed bacteria. Finally, the air in daily life contains trace bacteria. No matter what kind of compressor (dry type, scroll, water lubrication, etc.) is used, the air of dry compression equipment has no sterilization effect after passing through the compression chamber for a short time. If the air requirement is extremely high, it is recommended to add a sterilization filter after treatment.
3. The water consumption of the air compressor without oil and water lubrication is large. Do you need to replenish water into the machine all the time, and the machine needs to drain water outside all the time? Trouble and waste a lot of water?
The water-lubricated oil-free screw machine does not need to replenish water all the time, just like the washing machine at home turns on the faucet, and only when the water is replaced will the water be replenished. There is a water level sensor inside the machine can automatically drain and replenish water, and automatically drain a part of the water every 200 hours to replenish a part of the water. For example, a 110KW water lubrication, lubrication water volume is 130 liters, according to 8000 hours a year, need to change water 6000 liters, that is, 6 tons of water, even if double throw is 12 tons, per ton of water 5 yuan only need 60 yuan water charges per year is enough, very save water and money.
4. Is it good to use water as lubricant for lubrication, and does the machine have a long service life?
The role of water in the machine is to cool, seal, and lubricate. Secondly, the main engine and system of water-lubricated oil-free screw compressor generally use SUS304 and other food and medical grade materials. The main engine has been independently developed and produced. It has been tested by the market and has strong stability. In terms of air quality, pure oil-free energy saving is highly reliable, which proves its advanced technical quality.
Water lubricated oil-free screw air compressor is also called water jet screw air compressor, that is, screw air compressor, there are also single screw air compressor, which means that the rotor chamber sucks in air at the same time, but also sucks in water (plays the role of lubricating the rotor and sealing)
Need to purchase a water-lubricated air compressor, provided that the oil-free compressor brand which is better? Choose the water-lubricated oil-free air compressor produced by Shanghai Granklin Group.
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 detailsThe simplest point is to see whether it contains a frequency converter, and the second is to see whether the motor changes its speed according to the actual working conditions during operation. There are many factors to look. Speed directly affects the oil pressure and high and low pressure. I can see whether there is frequency conversion in current or not. Literally understood, the speed of the variable frequency air compressor is almost the same as the fixed frequency under the working state. When the air compressor is not in the pumping state, the motor frequency will automatically drop and the input power will be reduced to achieve the effect of energy saving.
Principle of screw air compressor 1. Suction process: The screw-type intake side suction port must be designed so that the compression chamber can fully inhale, and the screw compressor does not have an intake and exhaust valve group. The opening and closing of a regulating valve is adjusted, when the rotor
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 air compressors and water lubricated air compressors.
Contemporary screw air compressor not only uses the traditional screw, its structure, technology, but also uses a variety of materials, design and manufacture of a wide range of equipment models, the use of advanced technology developed products, so that a certain amount of screw and other materials can meet the user labor, production
As a common equipment in the industrial field, the noise level of the permanent magnet screw air compressor is one of the focuses of the user's attention. Generally speaking, the noise level of permanent magnet screw air compressor is between 65 decibels and 85 decibels, which is suitable for most industrial applications. Specifically.
When you need "oil-free air compressor" to provide "oil-free air" for the production of enterprises, will fall into a difficult problem of choice, so many types and brands of "oil-free air compressor", pick the eye. We can look at the difference between "power frequency air compressor" and "frequency conversion air compressor" to decide how to choose and purchase. If you need "water lubricated air compressor" or "oil free air compressor" may wish to contact us "Shanghai granklin group".
