Product Description

25Nm3/h 200bar High Pressure Oil-free Helium Compressor CE Certified

Minwen high pressure industrial gas compressor belongs to oil-free reciprocating piston type construction. It is divided into three-stage, four-stage or five-stage compression according to the displacement and pressure. It is divided into air-cooled type and water-cooled type according to the cooling type.

 

An oil-free compressor is a type of gas compressor that operates without the need for lubricating oil in the compression chamber. Traditional gas compressors use oil to lubricate the moving parts and provide a better seal between the compression chamber and the piston or rotor. However, in certain applications where oil contamination is a concern, such as medical and dental facilities, food processing, electronics manufacturing, and painting, oil-free compressors are preferred.

There is no lubricating oil inside the gas compressors, grease lubricated sealing type bearing is adopted for the rotary moving components, the moving seals inside the cylinder are made of self-lubricating material so as to ensure that the compressed gas will never contact any oil.

2. Reduced Maintenance: Oil-free compressors eliminate the need for oil changes, filter replacements, and oil disposal, resulting in lower maintenance requirements and costs.

3. Environmental Friendliness: The absence of oil reduces the risk of oil leaks or spills, making oil-free compressors environmentally friendly.

4. Improved gas Quality: Oil-free compressors provide cleaner gases, free from oil aerosols or vapors, which is essential in sensitive applications like medical and dental procedures or electronics manufacturing.

 

Features

Helium gas has a density that is 86% less than air. This means that the compressor has to be built to extremely tight tolerances to effectively compress helium gas without excessive blow-by. Furthermore, helium releases large amounts of heat when compressed, which the helium compressor must be able to absorb and shed. Thereore, for helium comoressors, we use water cooling for increased cooling efficiency.

Typical helium applications include recovery and compression systems for liquid cooling used in research institutions, particle accelerators, nuclear, medicine, aerospace, and militari missile applications. Helium recovery and compression is also used in general industrial applications, commercial merchant gas filing plants, heliostat applications, and helium mining, etc.

What Is the Role of Water Separators in Water-Lubricated Compressors?

In water-lubricated compressors, water separators play a crucial role in maintaining the integrity and performance of the compressed air system. Here’s a detailed explanation of their role:

Water separators, also known as moisture separators or condensate separators, are components within the compressed air system that are specifically designed to remove water or moisture from the compressed air stream. They help ensure that the compressed air remains dry and free from excessive moisture, which can cause various issues in the system and downstream equipment.

The primary role of water separators in water-lubricated compressors is to separate and remove water that is present in the compressed air due to the compression process and condensation. Here’s how they accomplish this:

  1. Condensate Separation: During the compression of air, moisture present in the air is compressed along with the air molecules. As the compressed air cools down after the compression stage, the moisture condenses into liquid form. Water separators are designed to efficiently separate this condensate from the compressed air stream, preventing it from entering downstream equipment, pipelines, or end-use applications.
  2. Gravity and Centrifugal Separation: Water separators utilize various separation principles to separate the condensate from the compressed air. Gravity-based separators rely on the difference in density between the water droplets and the compressed air to allow the water to settle at the bottom of the separator, where it can be drained out. Centrifugal separators use centrifugal force to spin the air and water mixture, causing the water droplets to be thrown outwards and collected in a separate chamber.
  3. Coalescing and Filtration: Water separators often incorporate coalescing and filtration mechanisms to enhance their efficiency. Coalescing filters are used to capture and merge small water droplets into larger droplets, making it easier for the separator to separate them from the compressed air. Filtration elements, such as fine mesh or media, may be incorporated to remove any remaining water droplets or particulate matter that could potentially pass through the separator.
  4. Automatic Drainage: To ensure continuous and efficient operation, water separators are equipped with automatic drain valves. These valves periodically or on demand, expel the collected condensate from the separator. Automatic drainage prevents the accumulation of water in the separator, which can lead to reduced separation efficiency, increased pressure drop, and potential damage to downstream equipment.

By effectively removing water and moisture from the compressed air stream, water separators help prevent issues such as corrosion, clogging, freezing, and degradation of pneumatic equipment and processes. They contribute to maintaining the quality and reliability of the compressed air system while protecting downstream components and applications from the negative effects of moisture.

It is important to note that proper sizing, installation, and maintenance of water separators are essential to ensure their optimal performance. Regular inspection and maintenance of the separators, including draining the collected condensate, replacing filtration elements, and checking for any leaks or malfunctions, are necessary to ensure the efficient operation of water-lubricated compressors and the overall compressed air system.

How Does Water-Lubrication Affect the Lifespan of Air Compressor Components?

Water-lubrication can have both positive and negative effects on the lifespan of air compressor components. Here’s a detailed explanation of how water-lubrication can impact the lifespan of air compressor components:

Positive Effects:

  • Lubrication: Water-lubrication provides effective lubrication to the moving parts of the air compressor, reducing friction and wear. Proper lubrication helps minimize the stress on components such as pistons, cylinders, and bearings, which can contribute to extended component lifespan.
  • Cooling: Water-lubricated systems offer efficient cooling properties. The circulation of water through water jackets or cooling channels helps dissipate heat generated during compression. Effective cooling can prevent excessive temperature rise, reducing the risk of thermal damage and prolonging the lifespan of compressor components.
  • Contaminant Control: Water-lubrication can aid in controlling contaminants within the compressor system. Water acts as a medium to trap and remove particulate matter or debris generated during compressor operation. This helps protect components from potential damage and contributes to their longevity.

Negative Effects:

  • Corrosion: Water-lubrication introduces moisture into the compressor system, which can increase the risk of corrosion. Corrosion can degrade the integrity of components, leading to reduced lifespan and potential failures. Proper corrosion prevention measures, such as using corrosion-resistant materials or implementing water treatment processes, are essential to mitigate this negative effect.
  • Contamination: Although water-lubrication can help control contaminants, it can also introduce impurities and contaminants if the water supply or treatment is not adequately managed. Contaminants such as sediment, minerals, or microbial growth can negatively impact component lifespan by causing blockages, wear, or chemical degradation. Regular maintenance and proper filtration systems are crucial to minimize contamination-related issues.
  • System Complexity: Water-lubricated systems can be more complex than oil-lubricated systems, requiring additional components such as water pumps, filters, and separators. The complexity of the system can introduce more points of failure or maintenance requirements, which, if not addressed properly, can affect the overall lifespan of the compressor components.

Proper maintenance, monitoring, and adherence to manufacturer guidelines are essential to maximize the positive effects and mitigate the negative effects of water-lubrication on air compressor components. Regular inspection, cleaning, lubrication, and water treatment can help ensure optimal operation and prolong the lifespan of the compressor components.

Advantages of Using Water as a Lubricant in Air Compressors

Water can be used as a lubricant in air compressors, offering several advantages over traditional lubricants such as oils or synthetic lubricants. Here are some of the advantages:

  1. Cost-effective: Water is a readily available and inexpensive resource, making it a cost-effective lubricant option for air compressors. Compared to oils or synthetic lubricants, water is significantly cheaper, which can result in cost savings for businesses and industries that heavily rely on air compressors.
  2. Environmentally friendly: Water is a non-toxic and environmentally friendly lubricant. It does not contain harmful chemicals or pollutants that can contribute to air or water pollution. Using water as a lubricant in air compressors reduces the risk of contamination and minimizes the environmental impact associated with traditional lubricants.
  3. Improved heat dissipation: Water has excellent heat transfer properties. It can absorb and dissipate heat more efficiently compared to oils or synthetic lubricants. Air compressors generate heat during operation, and using water as a lubricant helps to dissipate this heat effectively, preventing overheating and prolonging the lifespan of the compressor.
  4. Reduced fire hazard: Compared to oils or synthetic lubricants, water has a significantly higher flash point, which means it is less likely to ignite or contribute to fire hazards. This fire-resistant property of water makes it a safer lubricant choice, especially in environments where fire safety is a concern.
  5. Lower maintenance requirements: Water does not leave behind sticky residues or deposits, as some oils or synthetic lubricants might. This characteristic reduces the maintenance requirements of air compressors. It simplifies the cleaning process and reduces the frequency of lubricant changes, resulting in reduced downtime and maintenance costs.

Overall, using water as a lubricant in air compressors can offer significant advantages in terms of cost-effectiveness, environmental friendliness, heat dissipation, fire safety, and maintenance requirements.
