What is Piston Air Compressor

 

A piston/reciprocating compressor is a positive-displacement air compressor using a crankshaft powered by a piston and cylinders. It raises pressure through the mechanical action of a series of pistons. This gets the job done, but it also causes a lot of friction. The process of compressing air decreases its volume while increasing its density without turning it into liquid. Early reciprocating compressors were temperamental and often difficult to keep fully lubricated. Over time, compressor manufacturers have gradually adjusted the size, design, and material composition of the pistons. They have also experimented with new ways to maintain optimal lubrication.

What are the advantages of Piston Air Compressor?
 

Reciprocating Compressor Technology is Low Price
Piston technology compressors are the oldest types of compressor. They are also the simplest, using very basic physics principles to function. For these reasons, revolutionary changes and improvements in this field are unlikely. But that also means the technology is well understood by all its manufacturers, at least in its most common industrial usage. With little to no research and development cost, as well as simple and well-understood technology, the cost of production is lower. That means a wider range of manufacturers are willing to take on the product or license it under their own label. As such, the buyer benefits from a competitive market which makes for a lower cost of purchase.

 

Maintenance Technicians are Easier to Find
The age and simplicity of the technology, as well as the research plateau, impacts maintenance in the same way it affects production. For its most common industrial usage, there is no continuous learning process to stay on top of changes in piston compressors. Once a technician understands the basic principles, their skills can only improve. This means piston compressor maintenance is easier to master because the technology is accessible to any technician. You have access to a larger pool of technicians experienced in this technology. Most of the time, the competitive nature of this pool of resources also means a lower cost of maintenance.Piston compressor spare parts are readily available

 

Technician with Compressor Spare Parts
The availability of spare parts goes hand in hand with the maintenance of your piston compressor. Simple technology results in a high availability of spare parts and maintenance kits. This is especially relevant in light of the many compressors produced under private labels by the same manufacturer.
For the everyday hobbyist compressor spares, the buying alternatives are as varied as there are ways to buy the compressor itself. You can speak with authorised dealers, you can visit your nearest DIY shop, or go for e-commerce sites. Whichever you choose, chances are high that you will find all the spare parts your compressor needs. Or you will find suitable alternatives with the help of the online community.

Working Principle of Piston Air Compressor

 

1. Compression Process

When the piston is in the lowest position (called the inner dead centre or bottom dead centre), the cylinder is filled with low-pressure refrigerant vapour inhaled from the evaporator, and the suction process ends.Driven by the crankshaft and connecting rod, the piston starts to move upward. At this time, the suction valve is closed, the working volume of the cylinder is gradually reduced, the gas in the cylinder is compressed, and the temperature and pressure are gradually increased. The process of gas rising from the low pressure of suction to the exhaust pressure in the cylinder is called compression process.
Compression process is generally regarded as an isentropic process.

2. Exhaust Process

The piston continues to move upward when the pressure of the gas in the cylinder rises slightly above the pressure of the gas in the exhaust chamber.When the exhaust valve is opened, the high-pressure steam in the cylinder is discharged out of the cylinder under constant pressure until the piston reaches the top position (called the outer dead center or top dead center), and the exhaust process ends.

3. Expansion Process

When the piston moves in the cylinder, the upper end of the piston does not coincide with the top of the cylinder completely, but there is a certain space to ensure the safety and reliability of its operation. This space is called the residual space volume.Due to the residual space volume, when the piston moves to the top dead center, the exhaust is terminated, and a small part of the high pressure gas in the cylinder can not be discharged. When the piston moves in the reverse direction, only when the high-pressure gas expands to a pressure slightly lower than the suction pressure, the suction valve will open and the low-pressure gaseous refrigerant can enter the cylinder.

4. Suction Process

As the piston moves downward, the expansion process of high pressure gas in the residual space volume ends, the suction process begins. The low-pressure gas is sucked into the cylinder until the piston moves to the bottom dead centre.By far the compressor has completed a working cycle composed of compression, exhaust, expansion and suction.After that, the piston moves downward again, repeating the above four processes, and so on. This is the ideal working process and principle of piston compressor.

5. Refrigeration Process of Piston Compressors

The refrigeration process is carried out in the closed circulation system composed of ammonia compressor, cooler, regulating valve and evaporator.After the ammonia liquid pressure was reduced through the regulating valve, it enters the evaporator, absorbs the heat of the cooling medium and evaporates, so as to reduce the medium temperature and achieve the purpose of refrigeration.

 

 
How Should I Choose a Piston or Screw Compressor?
 
01/

Initial Cost Vs Operating Costs

Budgeting for a compressor shouldn't only include how much you pay for your compressor upfront; you also need to consider how much you'll pay for your compressor in the long run (i.e. your overall operating costs). As much as 70-75% of a compressor's lifetime operating costs are spent on energy usage, so keep that in mind when selecting a compressor technology. Pistons have a lower initial cost than screws, but screws cost much less to operate over time.

02/

Energy Efficiency

If both a piston and a screw were running the same amount of hours, the screw compressor will be much more efficient and have lower operating costs than the piston over the lifetime of the compressor. When selecting a technology, ask yourself: Is the initial or lifetime cost more important to you and your business?
Duty Cycle. Because piston compressors are limited in their duty cycles, they're ideal for applications with low duty cycle requirements and low daily running hours. Screw compressors, however, have long duty cycles. In fact, screws are engineered to run 100%, all day, every day!

03/

Service Intervals

There are more moving parts in a piston compressor than in a screw, which results in increased machine wear and tear. Screw compressors don't have as much wear; hence, they have reduced maintenance needs. But keep in mind that it's important to keep any type of compressor on a consistent maintenance schedule! This will help ensure machine efficiency and optimal system performance.

04/

Noise Levels

Piston compressors are loud – especially in comparison to screw technology. If you're looking for a lower-noise machine or a low noise level is required, you may want to consider a screw compressor.

 

 
How to Changing Your Pump Oil for air compressor

 

Air compressor spring cleaning
Keep your compressor running smoothly and efficiently with a new batch of oil, completely removing and replacing the oil in your unit. Here are some tips on how to do that:
● Turn your air compressor off and unplug it, or otherwise remove it from the power source.
● Consult the owner's manual for recommended fluid type and required amount.
● Let it rest for quite a while — the pump head and surrounding metal can become extremely hot during use.
● Check that the surface you're working on is flat and level.
● Remove your fill cap and/or plug.
● Place a container underneath the oil drain cap, and make sure it's large enough to hold more oil than your unit holds.
● Remove the oil drain cap — if you have to twist, it'll be counter-clockwise — and let the oil drain out of your unit.
● Replace the oil drain cap and tighten it as securely as you can. We recommend you use plumbers' tape to help create a proper seal.
● Fill your crankcase with the right amount of oil, which is usually denoted on the unit. Typically, you won't want to exceed the halfway point of the sight glass, because oil expands with heat and you're working with cool, dense oil right now.
● This can also be a good time to check and change your separator element. This element prevents excessive oil from getting into the system, and it should be replaced roughly every 1,000 work hours.

 

 
What is a Reciprocating or Piston Compressor Used for?

 

Piston compressors are suitable for small compressed air requirements. One-stage compressors produce pressures up to about 8 bar, while several stage versions produce up to 15 bar.
Operation should be intermittent. An air-cooled piston compressor's load level should not exceed 60-70%. After 2 minutes of compression, the compressor must rest for at least 1.5 minutes. We recommend keeping the total compression time per day to approximately 4 hours.
Piston or reciprocating compressors are mostly used in these types of industrial settings:
●Gas processing
●Chemical industries
●Oil plants and refineries
●Refrigeration technology
However, due to the wide variety of reciprocating compressors, they are used in almost every work setting. Although they have more maintenance requirements, they are very energy-efficient.
Although piston compressors are available in lots of different configurations in smaller industries, they are most commonly used in:
●Auto repair shops
●DIY-settings
●Workshops

Frequently Asked Questions

 

Q: What is piston compressor in AC?

A: A piston compresses the air by moving up and down inside a cylinder. The vacuum effect created by this motion sucks in the refrigerant gas. A reciprocating AC can suffer failures related to piston wear-out, but the potential to use up to eight cylinders makes it highly efficient.

Q: Which compressor uses a piston?

A: A reciprocating air compressor uses positive displacement to function. That means that they generate compressed air through a system of valves and pistons, much like the combustion engine in your car.

Q: What is the working principal of piston compressor?

A: Reciprocating (or piston) compressors compress air by using cylinders, pistons and cranks. These elements are powered by an electric or combustion engine. The air is moved into the cylinder and then compressed by the pistons. The compression can have one or more stages until the right operational pressure is reached.

Q: Are piston compressors good?

A: Because piston compressors are limited in their duty cycles, they're ideal for applications with low duty cycle requirements and low daily running hours. Screw compressors, however, have long duty cycles. In fact, screws are engineered to run 100%, all day, every day!

Q: What is the efficiency of piston compressor?

A: A system of valves allows air in and out of these piston chambers. These compressors offer a wide range of efficiency levels, with high-speed models ranging from 70% to 85% and low-speed models topping 90%. Their most common use is in building automation systems.

Q: What is the speed of piston compressor?

A: The optimum piston speed usually falls in 3–4.5 m/s range. Large- and medium-size machines typically operate at around 300–350 rpm, while small compressors (say, <250 kW) may run at up to 600 rpm.

Q: What is the main use of compressor?

A: All air compressors perform the same basic function — they increase the pressure and reduce the volume of a gas, like air.

Q: How does a piston compress air?

A: When the cylinder volume is occupied completely by air, it is said to be 'charged'. Once the cylinder is fully charged, the piston begins moving towards the suction and discharge valves; this is referred to as the 'discharge stroke' or 'compression stroke'. As the piston moves, it compresses the air.

Q: What is the principle of law of air compressors?

A: Boyle's law states that if the temperature is constant (isotherm), then the product of the pressure and volume are constant. Charles's law says that at constant pressure (isobar), the volume of a gas changes in direct proportion to the change in temperature.

Q: Which compressor has highest efficiency?

A: A rotary screw compressor is most efficient when running in a 100 percent loaded condition. (Loaded, means the compressor is producing air; while unloaded means the compressor remains idle.) A compressor will continuously load when its air production capacity matches the air requirement.

Q: What is the difference between screw and piston compressor?

A: Screw air compressors use two meshing helical screws, while piston air compressors use pistons driven by a crankshaft. Another difference is the moving parts as the screw compressor has two moving parts which are not in contact while the piston compressor has a lot of moving parts.

Q: What is the formula for piston speed?

A: There's a simpler formula, but more on the math later. A piston's velocity constantly changes as it moves from top dead center (TDC) to bottom dead center (BDC) and back to TDC during one revolution of the crankshaft.

Q: What is the pressure ratio of piston compressor?

A: Usually single-stage turbocharging can deliver a compressor pressure ratio around 3.5–4.5, depending on its wheel material and design. Compressor speed is limited by the allowable centrifugal force exerted upon the compressor wheel.

Q: What is the speed of piston compressor?

A: The optimum piston speed usually falls in 3–4.5 m/s range. Large- and medium-size machines typically operate at around 300–350 rpm, while small compressors (say, <250 kW) may run at up to 600 rpm.

Q: What is normal piston compressor?

A: Essentially, a piston compressor contains a valve system and two valve discs. When the piston moves down, it draws air into the cylinder. One of the valve discs folds downward, allowing the air to pass. When the piston moves upward, the large disc also folds upwards and closes.

Q: Are piston compressors good?

A: Because piston compressors are limited in their duty cycles, they're ideal for applications with low duty cycle requirements and low daily running hours.
