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.

Choose an Air Compressor for Your Business

There are several factors to consider when choosing an air compressor for your business. One factor to consider is the type of compressor you are looking for, which may include single-stage, low noise, and positive displacement. Hope this article helps you make the right decision. After all, your business success will depend on this device! Let’s take a closer look at these factors. Also, consider what compressor manufacturers say about their products.

Positive displacement

Positive displacement air compressors compress air by drawing in a volume from an inlet and extruding it out of a chamber. This increases the pressure at which the gas can be pumped at rates that cannot be pumped through the outlet at lower pressures at higher mass flow rates. These types of compressors are available in single-acting and double-acting configurations. They are classified by the number of cylinders.
There are 2 different types of air compressors: reciprocating air compressors and screw compressors. Both are roll machines. Positive displacement air compressors use pistons and cylinders to compress air. The resulting air pressure builds up within the compressor housing, increasing the potential energy of the compressed air. Screw air compressors are the most popular positive displacement air compressors, which can be either single-stage screw-blade air compressors or multi-stage screw-blade oil-immersed screw air compressors.
Positive displacement flowmeters use a rotating measuring chamber to divide the fluid into discrete quantities. The number of times the chamber was refilled and emptied was used to estimate the total flow. However, positive displacement flow meters are prone to leaks, reducing the accuracy of the estimates. If a leak occurs, it can cause false readings and damage the compressor. However, leaks in positive displacement air compressors can reduce pressure.
The most common types of positive displacement air compressors are screw, reciprocating, and vane. Rotary positive displacement air compressors are also available as well as many other air compressors. Positive displacement air compressors are most commonly used in large manufacturing facilities. If you are considering an air compressor for commercial or industrial applications, it is imperative to understand how the components of the unit work. Please read the information below to learn more before deciding which application is best for you.
Positive displacement air compressors use a piston to force air into a chamber, compressing the air in the process. The piston moves in the opposite direction, thereby reducing the volume of the chamber. When the amount of air in the chamber reaches its maximum value, the valve opens, allowing it to escape at higher pressure. Positive displacement air compressors are generally less efficient than centrifugal compressors. However, they are still an excellent choice for a variety of applications.

Single-stage

The discharge pressure of the single-stage air compressor is used to control the operation of the compressor. Properly designed load/unload controls allow the air compressor to operate at its most efficient point while minimizing stress on the main engine bearings. Single-stage air compressors can approach variable speed efficiency with appropriate storage capacity. However, improper storage can cause premature bearing wear on the main unit. If this is the case, a single-stage air compressor may not be ideal.
A single-stage air compressor has only 1 cylinder, which means 1 stroke is required to move air from 1 cylinder to another. Pressure is measured in cubic feet per minute or CFM. Tank size is also important as a large single-stage air compressor may be required to operate multiple air tools. Single-stage air compressors can be used in a variety of applications and can last for years.
For the most common uses, single-stage air compressors are the most practical option. These devices work with most hand tools, from hammers to grinders. Single-stage air compressors are lightweight and easy to move. However, two-stage air compressors provide more CFM, making them a better choice for industrial or commercial use. However, two-stage compressors are not suitable for private use. Therefore, if your main purpose is DIY and craft projects, it is better to choose a single-stage air compressor.
Compared with two-stage air compressors, single-stage screw air compressors are cheaper. They come from a variety of manufacturers and range in power from 3 to 600 horsepower. Single-stage air compressors are a cost-effective solution for a variety of air compressor needs. They offer flexibility and multiple control methods, making them an excellent choice for many different applications. Therefore, when choosing an air compressor for your business, choose the 1 with the most suitable functions.
Single-stage air compressors are the most affordable and easy-to-use air compressors for small to medium jobs. They also have higher compression ratios. The compression ratio is the ratio of absolute discharge pressure to absolute inlet pressure. When calculating the ratio, it takes into account atmospheric pressure and gauge pressure. The compression ratio pushes the surface area of ​​the rotor, which increases the thrust load.
Single-stage air compressors are smaller and easier to transport than two-stage units. Single-stage air compressors have 1 air intake, and two-stage air compressors have 2 air intakes. The difference between single-stage and two-stage air compressors largely depends on the number of times the air is compressed. A single-stage air compressor compresses the air once, while a dual-stage air compressor compresses the same amount of air twice.

low noise

Low noise air compressors are ideal for a variety of applications. While no air compressor is completely silent, some models are much quieter than others. For the Hitachi EC28M portable compressor, the noise level is 59 decibels. The compressor features steel rollers that protect the internal components and give it a sleek, modern look. It also has a one-gallon fuel tank and a half-horsepower drive.
Noise from air compressors can be distracting and reduce productivity. It is important to choose low-noise air compressors to keep employees healthy and happy at work. While noise is an unfortunate aspect of working on the shop floor, reducing it can improve productivity. By reducing distracting noise, employees can focus on their work and communicate more effectively. That means higher quality work and happier clients. If you’re looking for a low-noise air compressor, be sure to read the tips below.
Low noise air compressors are an excellent choice for businesses of all sizes. These powerful tools can run multiple tools simultaneously. The 2 water tanks are made of rust-resistant aluminum and are stackable. This air compressor is heavier and can handle large jobs with ease. It costs more than other air compressors, but it can handle a lot of work efficiently. CZPT Air Tools air compressors come with a one-year warranty and are highly recommended by contractors.
Noiseless air compressors are generally more expensive than comparable products, but they are worth the extra cost. Noiseless compressors are a good option for businesses that need to avoid disturbing nearby people. For example, you might want to consider a low-noise air compressor for a dental office, which cannot tolerate noise. Fortunately, this problem can be solved by relocating the compressor to a location that is more isolated from your workspace.
One brand of low-noise air compressors offers 2 models. The CZPT Air Tools 2010A features a large cast aluminum can, regulating pressure gauge, and 2 universal quick-connects. It produces 68 decibels of noise when it works. It has a large 8-gallon fuel tank capacity and has wheels and handles for easy transport. Its powerful engine produces a low noise level of 68 decibels.
Another popular low noise air compressor is the Makita MAC210Q Quiet Series. This model is capable of producing up to 71.5 decibels of sound, which is the amount of air it produces at 90PSI. The MAC210Q features a durable oil-free pump and weighs just 36 pounds with a handle and wheels. These compressors are easy to move and ideal for indoor work.
