Main technical data

Cylinder 
All the cylinders comprise upper plate, diaphragms, and cylinder body etc. The diaphragms are clamped between the cylinder cover and cylinder body. The cylinder cover and cylinder body each has a concave recess hollowed out in their contacting faces. The gas cylinder is formed between cylinder cover concave recess and diaphragms. Both suction valve and discharge valve are fitted on the upper plate. Among of them, the discharge valve is located on the center of the upper plate. The evenly located small oil holes are on the cylinder body to deliver the oil pressure inside the oil cylinder to the bottom of diaphragms (each diaphragm compressor’s cylinder has 3 piece diaphragm.) 

Pressure Regulating Valve 
The oil pressure of oil cylinder is regulated by the tension of the valve spring.In case the oil pressure is higher than the regulated value, turn the regulating bolt counter-clockwise to loosen the spring tension, but turn the regulating bolt clockwise to tighten the spring, when the oil pressure is lower than the regulated value. When the oil pressure meets the required value, the regulating bolt must be locked with a lock-nut. The oil pressure of the oil cylinder shall always be higher than the discharge pressure by 15~20%. But the oil and gas differential pressure shall not be lower than 0.3MPa or higher than 1.5MPa. 

Cooler
The cooler structure is the double-wall pipe type. The circular space between the outer and inner pipe is the cooling water passage and the inner pipe is the gas passage. Normally the water inlet port is at the lower side and the water outlet port is at the upper side. The flow direction of cooling water and gas is on the contrary.

Oil Pressure Measuring Device 
The measuring device of oil cylinder discharge pressure consists of shock-proof pressure gauge, check valve and unloading valve. The case of the pressure gauge is totally airproof and filled with damping liquid. The inner devices of gauge is immersed in the liquid, which makes the pressure gauge hands stable through the function of the viscosity of damping liquid. The unloading valve is fitted under the gauge to discharge the remained air in the oil pipeline and to unload the oil pressure gauge. Also the check valve connecting with oil cylinder through pipeline is fitted under the unloading valve.   

Oil pipes 
Oil pipes consist of lube oil pipe and oil pressure secure system.
The lubrication for the driving device adopts gear oil pump circulation pressure lubricating. The lube oil stored in the frame oil tank enters into the gear oil pump after being filtered and is pressed into the oil holes in the crankshaft through the gear oil pump to lubricate the crankshaft friction surface. At the same time, part of the lube oil reaches the crosshead pin and crosshead along the oil holes in the connecting rod to lubricate the friction surface. The oil pressure of gear oil pump shall be kept between 0.3~0.5Mpa, and the bearings at the 2 ends of crankshaft is splash lubricated. 
Oil pressure secure system consists of oil compensating pipe, pressure-measuring pipe and oil return pipe. The oil output from the oil compensating pump will supplement oil for compressor cylinders through the oil compensating pipe and the excess oil returns to the crankcase through the pressure-regulating valve.

What Is the Role of Air Dryers in Oil-Free Air Compressor Systems?

Air dryers play a crucial role in oil-free air compressor systems by removing moisture from the compressed air, ensuring dry and moisture-free output. Here’s a detailed explanation of the role of air dryers in oil-free air compressor systems:

1. Moisture Removal:

One of the primary functions of air dryers in oil-free air compressor systems is to remove moisture from the compressed air. During the compression process, atmospheric air is compressed, leading to an increase in temperature. As the compressed air cools down, the water vapor present in the air can condense, resulting in the formation of liquid water. Moisture in the compressed air can cause a range of issues, including corrosion, damage to pneumatic equipment, reduced efficiency in downstream processes, and contamination of products or processes. Air dryers effectively remove this moisture, ensuring that the compressed air remains dry and free from water vapor.

2. Condensation Prevention:

Air dryers also help prevent condensation from occurring within the compressed air system. By removing moisture from the compressed air, air dryers minimize the chances of condensation forming in the compressed air lines, storage tanks, and downstream equipment. Condensation can lead to the accumulation of water, which can cause blockages, corrosion, and other operational issues. Air dryers help maintain the integrity and reliability of the compressed air system by preventing condensation-related problems.

3. Protection of Equipment:

Moisture in the compressed air can be detrimental to pneumatic equipment and tools. Air dryers help protect this equipment by ensuring that the air supplied is dry and free from moisture. Dry air prevents corrosion of internal components, extends the lifespan of pneumatic tools, and helps maintain their optimal performance. By removing moisture, air dryers contribute to the overall reliability and efficiency of the oil-free air compressor system.

4. Purification of Compressed Air:

Air dryers also aid in the purification of compressed air by removing impurities and contaminants, including water vapor, oil droplets, and solid particles. While the primary purpose of air dryers is to remove moisture, they often incorporate additional filtration stages, such as coalescing filters or desiccant beds, to capture and remove other impurities. These filtration stages work in conjunction with the drying process to deliver clean, dry, and purified compressed air that meets the required air quality standards.

5. Optimal Performance:

Properly dried and moisture-free compressed air ensures optimal performance in various applications. In industries such as food and beverage, pharmaceuticals, electronics manufacturing, and painting, where air quality is critical, the use of air dryers is essential to meet specific air purity requirements.

What Is the Role of Filtration in Maintaining Air Quality in Oil-Free Compressors?

Filtration plays a crucial role in maintaining air quality in oil-free compressors. Here’s a detailed explanation of the role of filtration and its importance in ensuring clean and contaminant-free compressed air:

1. Removing Solid Particles:

One of the primary functions of filtration in oil-free compressors is to remove solid particles from the compressed air. Ambient air contains various contaminants such as dust, dirt, pollen, and other particulates. These particles can potentially damage downstream equipment, clog pneumatic components, and compromise the quality of the compressed air. Filtration systems, typically consisting of pre-filters and main filters, are used to capture and remove these solid particles, preventing them from entering the compressed air system.

2. Protecting Equipment:

Filtration helps protect the equipment and components of the compressed air system, including valves, cylinders, pneumatic tools, and instruments. Solid particles present in the compressed air can cause abrasion, wear, and damage to these components, leading to decreased performance, increased maintenance, and potential system failures. By effectively removing solid particles, filtration ensures the longevity and reliability of the equipment, reducing the need for frequent repairs and replacements.

3. Preventing Contamination:

Oil-free compressors are designed to produce clean, oil-free compressed air. However, certain contaminants can still find their way into the compressed air system. Filtration plays a vital role in preventing contamination by removing substances such as oil aerosols, water vapor, and microorganisms. These contaminants can be introduced through ambient air or can result from the compression process itself. Proper filtration ensures that the compressed air remains free from these contaminants, meeting the required air quality standards for specific applications.

4. Achieving Air Purity:

Many applications require compressed air with specific purity levels. For instance, in industries like pharmaceuticals, food and beverage, electronics, and healthcare, high-quality compressed air is essential to prevent product contamination or ensure the safety of sensitive processes. Filtration, along with other air treatment components such as dryers and separators, helps achieve the desired air purity levels by removing particulates, moisture, oil, and other impurities. This ensures that the compressed air meets the required standards and complies with industry regulations.

5. Extending Maintenance Intervals:

Efficient filtration in oil-free compressors can contribute to extended maintenance intervals. By effectively capturing and removing contaminants, filtration reduces the accumulation of debris and deposits within the compressed air system. This, in turn, reduces the frequency of maintenance tasks such as cleaning, purging, and component replacements. Extended maintenance intervals not only save time and labor but also minimize system downtime and associated costs.

6. Preserving Product Quality:

In applications where compressed air comes into direct contact with products or processes, maintaining air quality is crucial to preserve product integrity and quality. Contaminated compressed air can introduce impurities, odors, or foreign substances that may adversely affect the final product. Filtration ensures that the compressed air remains clean and free from contaminants, safeguarding the quality, purity, and consistency of the end products.

Overall, filtration plays a vital role in maintaining air quality in oil-free compressors. By removing solid particles, preventing contamination, achieving air purity, protecting equipment, extending maintenance intervals, and preserving product quality, filtration systems contribute to the reliable and efficient operation of compressed air systems in various industries and applications.

What Is an Oil-Free Air Compressor?

An oil-free air compressor, also known as an oilless air compressor, is a type of air compressor that operates without the use of lubricating oil in the compression chamber. Unlike traditional air compressors that rely on oil for lubrication and sealing, oil-free compressors employ alternative methods to achieve compression and deliver clean, oil-free compressed air. Here’s a detailed explanation of how oil-free air compressors work and their key characteristics:

Working Principle:

Oil-free air compressors utilize various techniques to compress air without the need for oil. The most common methods include:

  • Dry Compression: In this method, the compression chamber doesn’t have any oil present. Special materials, coatings, and surface treatments are used to reduce friction and wear between the moving parts, allowing for efficient compression without oil lubrication.
  • Water or Air Cooling: Oil-free compressors often employ advanced cooling mechanisms, such as water or air cooling, to dissipate the heat generated during compression. This helps to maintain the operating temperature within acceptable limits and ensures the longevity of the compressor.
  • Piston Rings and Seals: Instead of relying on oil for lubrication and sealing, oil-free compressors use specialized piston rings, seals, or other forms of dry frictionless technology. These components provide the necessary sealing and reduce internal friction, allowing for efficient compression without the need for oil.

Characteristics of Oil-Free Air Compressors:

1. Clean and Oil-Free Air: The primary advantage of oil-free air compressors is that they deliver air that is free from oil contamination. This makes them suitable for applications where oil contamination can be detrimental, such as in the medical, pharmaceutical, food and beverage, electronics, and automotive industries.

2. Low Maintenance: Oil-free compressors typically require less maintenance compared to oil-lubricated compressors. Since there is no oil to change or monitor, maintenance tasks related to oil filtration, oil changes, and oil disposal are eliminated. This can result in cost savings and reduced downtime.

3. Compact and Lightweight: Oil-free compressors are often designed to be compact and lightweight, making them portable and easy to transport. This makes them suitable for applications where mobility is required, such as construction sites, workshops, and on-site maintenance tasks.

4. No Oil Contamination Risk: With oil-free compressors, there is no risk of oil contaminating the compressed air system. This eliminates the need for additional filtration or separation equipment to remove oil from the compressed air, simplifying the overall system design.

5. Lower Initial Cost: In general, oil-free compressors tend to have a lower initial cost compared to oil-lubricated compressors. This can be advantageous for applications with budget constraints or when the specific requirements of the application align with the capabilities of oil-free compressors.

It’s important to note that oil-free air compressors may have certain limitations compared to oil-lubricated compressors. They may have lower maximum operating pressures and higher operating temperatures. Additionally, the absence of oil lubrication may result in slightly reduced efficiency and increased wear on certain components over time.

By understanding the working principle and characteristics of oil-free air compressors, users can determine whether this type of compressor is suitable for their specific application and requirements.
