A scroll compressor (also called the spiral compressor, scroll pump, and scroll vacuum pump) is a device for compressing air or refrigerant. It is used in air conditioning equipment, as an automobile supercharger (where it is known as a scroll-type supercharger) and as a vacuum pump.  Much residential central heat pump and air conditioning systems and a few automotive air conditioning systems employ a scroll compressor instead of the more traditional rotary, reciprocating, and wobble-plate compressors.

Product features

1) Silent mute and energy saving

The suction and exhaust are stable and keep high frequency so that the airflow pulsation is very small. The centrifugal fan for centrifugal air is used and the air duct is optimized to reduce the operation noise. The specific power is far lower than the traditional compressor, saving energy and environmental protection.

2) Clean and oil-free

During the operation of the equipment, there is no need to add lubricating oil, and the gas produced does not contain any oil, and at the same time, the occurrence of overheating life reduction caused by emulsification of oil compressor at low temperature is avoided.

3) Easy maintenance and low cost

The equipment has few parts, small volume, lightweight, no wearing parts, long service life, and very simple maintenance. Compared with the compressor with oil, there is no need to add lubricating oil, no oil mist filter, and the replacement cycle of main pipeline filter and the post-treatment filter element is greatly extended, which reduces the cost of pipeline cleaning and equipment maintenance, and there is no drainage treatment cost of oily wastewater.


Working principle

The moving disk rotates according to the sequence of figure 1-2-3-4-5. The moving and static disks mesh to form a number of crescent-shaped closed compression chambers. The gas is gradually compressed by the crescent-shaped compression chamber and then discharged from the exhaust port in the center of the static disk.

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.
air-compressor

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 2 lobes positioned in a circular cavity. One rotor is connected to an engine, while the other pushes the other 1 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 2 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.
air-compressor

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 1 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 2 valves – 1 for inlet and 1 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 1 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.
air-compressor

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 1 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 1 is an excellent choice.
