Working principle of piston compressor
When the crankshaft of the piston compressor rotates, the piston will reciprocate through the transmission of the connecting rod,and the working volume formed by the inner wall of the cylinder, the cylinder head and the top surface of the piston will periodically change. When the piston of a piston compressor starts to move from the cylinder head, the working volume in the cylinder gradually increases. At this time, the gas flows along the intake pipe and pushes the intake valve to enter the cylinder until the working volume reaches the maximum. , The intake valve is closed; when the piston of the piston compressor moves in the reverse direction, the working volume in the cylinder is reduced, and the gas pressure is increased. When the pressure in the cylinder reaches and is slightly higher than the exhaust pressure, the exhaust valve opens and the gas is discharged from the cylinder , Until the piston moves to the limit position, the exhaust valve is closed. When the piston of the piston compressor moves in the reverse direction again, the above process repeats. In short, the crankshaft of a piston compressor rotates once, the piston reciprocates once, and the process of air intake, compression, and exhaust is realized in the cylinder, which completes a work cycle.
Advantages of piston compressor
1. The applicable pressure range of the piston compressor is wide, and the required pressure can be reached regardless of the flow rate;
2. The piston compressor has high thermal efficiency and low unit power consumption;
3. Strong adaptability, that is, a wide exhaust range, and is not affected by the pressure level, and can adapt to a wider
pressure range and cooling capacity requirements;
4. Piston compressors have low requirements for materials, and use common steel materials, which is easier to process and lower in cost;
5. The piston compressor is relatively mature in technology, and has accumulated rich experience in production and use;
6. The device system of the piston compressor is relatively simple.
Note: In the unloading process, the compressor pressurizes the gas from the storage tank and then presses it into the tank car through the gas-phase pipeline, and presses the liquid from the tank car to the storage tank through the gas-phase differential pressure to complete the unloading process. When the gas phase is pressurized, the temperature of the gas phase will rise. At this time, forced cooling is not necessary, because if the gas phase is compressed and then cooled, it is easy to liquefy, and it is difficult to establish the pressure difference of the gas phase, which is not conducive to the replacement of the gas phase and the liquid phase. In short, it will cause the prolongation of the unloading process. If it is necessary to recover the residual gas, the cooler can be selected to forcibly cool the gas phase during the recovery operation, so as to recover the residual gas as soon as possible.The loading process is opposite to the unloading process.

What Is the Role of Air Receivers in Gas Air Compressor Systems?
Air receivers play a crucial role in gas air compressor systems by serving as storage tanks for compressed air. Here’s a detailed explanation:
1. Storage and Stabilization:
The primary function of an air receiver is to store compressed air generated by the gas air compressor. As the compressor produces compressed air, the air receiver collects and stores it. This storage capacity helps meet fluctuating demand in compressed air usage, providing a buffer between the compressor and the system’s air consumption.
By storing compressed air, the air receiver helps stabilize the supply to the system, reducing pressure fluctuations and ensuring a consistent and reliable flow of compressed air. This is particularly important in applications where the demand for compressed air may vary or experience peaks and valleys.
2. Pressure Regulation:
Another role of the air receiver is to assist in pressure regulation within the gas air compressor system. As compressed air enters the receiver, the pressure inside increases. When the pressure reaches a predetermined upper limit, typically set by a pressure switch or regulator, the compressor stops supplying air, and the excess air is stored in the receiver.
Conversely, when the pressure in the system drops below a certain lower limit, the pressure switch or regulator signals the compressor to start, replenishing the compressed air in the receiver and maintaining the desired pressure level. This cycling of the compressor based on pressure levels helps regulate and control the overall system pressure.
3. Condensate Separation:
During the compression process, moisture or condensate can form in the compressed air due to the cooling effect. The air receiver acts as a reservoir that allows the condensate to settle at the bottom, away from the outlet. The receiver often includes a drain valve at the bottom to facilitate the removal of accumulated condensate, preventing it from reaching downstream equipment and causing potential damage or performance issues.
4. Energy Efficiency:
Air receivers contribute to energy efficiency in gas air compressor systems. They help optimize the operation of the compressor by reducing the occurrence of short-cycling, which refers to frequent on-off cycling of the compressor due to rapid pressure changes. Short-cycling can cause excessive wear on the compressor and reduce its overall efficiency.
The presence of an air receiver allows the compressor to operate in longer and more efficient cycles. The compressor runs until the receiver reaches the upper pressure limit, ensuring a more stable and energy-efficient operation.
5. Air Quality Improvement:
Depending on the design, air receivers can also aid in improving air quality in the compressed air system. They provide a space for the compressed air to cool down, allowing moisture and some contaminants to condense and separate from the air. This can be further enhanced with the use of additional filtration and drying equipment installed downstream of the receiver.
In summary, air receivers play a vital role in gas air compressor systems by providing storage capacity, stabilizing compressed air supply, regulating system pressure, separating condensate, improving energy efficiency, and contributing to air quality control. They are an integral component in ensuring the reliable and efficient operation of compressed air systems across various industries and applications.

Choosing an Air Compressor
Considering a new Air Compressor? Here are some tips to make the decision easier. Learn the pros and cons of each type, including the differences between oil-injected and oil-free models, single stage and positive displacement. In addition, learn more about the different technologies that are available for your air compressor. It is important to choose an appropriate unit for the type of work you do. Here are some of the best compressors available today.
Positive displacement
There are several different types of air compressors, but most are positive displacement air compressors. They use a rotary or reciprocating component to compress air. The reciprocating component compresses air by reducing the volume of the chamber. Positive displacement compressors are used in bicycle pumps, chemical plants, and refrigerators. Positive displacement air compressors use multiple inlet ports. Despite the various types, the principle of operation remains the same.
Another type of positive displacement air compressor is a reciprocating piston. The piston inside a cylinder moves up and down, causing the compressed air to fill the upper part of the cylinder. These air compressors are used in a variety of different applications, including blowing bottles and gas pipelines. These air compressors can be water-cooled, lubricated, or non-lubricated. Different types have different capacities and air pressures.
A positive displacement flowmeter uses a rotating chamber that divides continuous fluid into discrete portions. The number of times the chamber is filled and discharged can be used to estimate the flow rate. The rotation speed of the measuring chamber is directly proportional to the flow rate. The drawbacks of this type of positive displacement flowmeter are that it is prone to jamming. If the fluid contains particles, it may be too thick for the meter to determine flow rate.
A negative displacement air compressor was invented in 1860 and is the oldest type of compressor. It uses two lobes positioned in a circular cavity. One rotor is connected to an engine, while the other pushes the other one to spin in the opposite direction. Negative displacement compressors are low-maintenance, but they do require more precision. They are often used in nuclear power plants because they use the kinetic energy of the rotating elements to produce pressure.
Oil-injected
Oil-flooded or oil-injected air compressors use liquid to seal and lubricate moving parts and reduce noise. Oil-flooded air compressors are effective for a variety of pneumatic tools and accessories. Some models have a thermostat that controls the amount of oil used during operation. Other types of oil-flooded air compressors are piston-type models. Here is an overview of the basic differences between these two air compressors.
An oil-injected air compressor is more expensive than a comparable oil-free air compressor, but its advantages far outweigh its disadvantages. An oil-free compressor is quieter, requires less maintenance, and has a lower price tag. It also offers a greater degree of air purity. A number of other advantages may also make this type of air compressor the better choice for many industrial settings. If you need a high-pressure compressor in a tight space, consider the benefits of an oil-free system.
Oil-injected air compressors require more maintenance than oil-free models. Both types of air compressors offer similar capacity and ISO 8573-1 Class 0 and 1-2 purity, but the oil-injected systems require more air-treatment components. They require an activated carbon filter and coalescing filter. Oil-injected air compressors will likely remain the standard for industrial air compressors for many years. And since their performance and efficiency are comparable, it may be worthwhile to invest in some point-of-use air treatment.
Both types of air compressors have their benefits. However, choosing between oil-free and oil-injected air compressors is not as straightforward as you might think. Whichever type you choose, make sure it will meet your needs. The benefits of an oil-injected air compressor outweigh their disadvantages. In general, oil-injected air compressors are more durable and can last longer than oil-free models. The only downside is their higher price.
Oil-free
When choosing an air compressor for your company, you’ll need to determine what it is going to be used for. For example, if you’re planning on using it to power multiple workers, you should consider getting an oil-free compressor. An oil-free compressor, on the other hand, is quieter and can power several workers at a time. If you’re a contractor, the most important consideration will be the type of jobs you’ll be doing. Higher air pressure means greater demand for air flow, and more pressure can damage the equipment.
Oil-free compressed air is certified 100% free of contaminants. Technically, oil-free air is not completely free of foreign matter, but it is extremely low within the limits of practical air quality. A technically oil-free air compressor might have a total oil level of 0.003 mg/m3. If you’re in need of a technically oil-free air compressor, you must install an air treatment equipment after your current compressor.
If you’re in the manufacturing industry, a good oil-free air compressor will save you money and reduce your environmental impact. Many of these tools require air compressors to work, and this equipment will ensure that they don’t get contaminated. To buy the best oil-free compressor, you should learn a bit about the different terms used by compressor repair companies. ACFM, for example, is the amount of air that can be compressed in one minute at rated conditions.
When you’re using an oil-free air compressor, you should know that the overall life of the device will be much shorter. Compared to an oil-flooded rotary screw air compressor, an oil-free compressor typically has a lifespan of 50 thousand hours. But it’s important to understand that this type of compressor can still cause damage to piping and processes. Therefore, you should choose an oil-free compressor when you need to clean air for your business.
Single-stage
A single-stage air compressor, also known as a piston air compressor, compresses air only once before storing it in a cylinder. This stored air has enough energy to power a variety of pneumatic tools, such as screwdrivers, chisels, and wrenches. These units are also ideally suited for low-flow applications and are widely used in gas stations, auto shops, and various manufacturing plants.
A single-stage air compressor uses two valves – one for inlet and one for outlet – to transfer compressed air. Both valves are actuated by springs. The inlet valve has a slight curvature to provide protection from damage. The compressor’s outlet valve opens when the pressure in the cylinder is higher than the pressure in the storage tank. The piston moves very quickly inside the cylinder, exerting a high amount of force throughout the compression process. This high piston speed is a common cause of compressor wear and tear.
A single-stage air compressor is ideal for smaller tradesmen and small construction crews. Its lightweight and compact design make it easier to transport and store. While it may be tempting to buy the first cheap air compressor you see, it’s important to balance the price against performance to choose the right air compressor for your needs. The best single-stage air compressor is one that provides excellent performance and durability. Its two-stage counterpart is designed for larger construction teams and large applications.
The main difference between a single-stage and a two-stage air compressor lies in their capacity. A single-stage air compressor compresses air only once and delivers it into the storage tank, while a two-stage compressor compresses it twice, creating double the pressure. Because of this, single-stage air compressors are cheaper and versatile than their counterparts, which means that they can be used for multiple purposes.
Low-noise
A low-noise air compressor is a type of industrial compressor that is less noisy than regular air compressors. These are generally smaller machines designed for smaller factories and workshops with a few to several employees. They are designed to handle mid-weight volumes of compressed air per day. This type of compressor is especially useful for smaller manufacturing businesses that need to produce compressed air for medical applications. Small breweries can also benefit from the low-noise capabilities of these compressors.
Low-noise air compressors come in various sizes and features. For smaller jobs, you can purchase a one-gallon model that is lightweight and portable. For larger jobs, you can purchase one with a larger tank that can provide more pressure for longer jobs. However, a larger tank will make the compressor heavier and harder to transport. To avoid this, make sure to check the size of the tank and how much power it can handle.
Considering a low-noise air compressor for your business? If so, you’ve come to the right place. There are a variety of affordable and dependable low-noise options to choose from. A CAT 10020C, for example, is designed to provide high-volume air to many outlets at once. A CAT 10020C comes with a 10-gallon tank, wheels, and a carrying handle.
Noise levels can also affect the productivity of employees. When employees work with air compressors in close proximity to each other, they may develop tinnitus. If employees are free from tinnitus because of the loud noise, they are likely to work more efficiently. Moreover, it will be easier for them to focus and communicate efficiently. If you need a compressor, a low-noise one is an excellent choice.
