At present, the compressors have gained wide popularity. They provide overwhelming assistance in solving everyday industrial or domestic tasks.
Any industrial enterprise uses compressors to reduce costs and energy costs. In everyday life there are also many tasks, the solution of which simplifies the compressor.
Types of tasks
For example, it can help in swapping gamingballs and other inflatable products. Also, the farm can be useful for spraying water or solutions on plants, cleaning up clogged pipeline communications. Compressor rotary can be useful in almost any field of human activity. From its reliability and quality depends on the performance of the tasks. Therefore, it is important to choose the right compressor, and also to find out what is the first thing to pay attention to when buying.
Compressors
The compressor is a special device for supplying air under pressure to a pneumatic tool. At the present time it is widely used in any human activity, even in art.
Compressor equipment is a device that generates air with excess pressure. Power and pressure depend on the type and type of device.
Особое распространение получили роторный compressor, rotor-blade, rotor-screw, rotary-piston, rotor-air, rotary-plate. Each of them has unique characteristics and parameters.
Types of compressors
Compressor rotary is a devicewith a compressive rotating element. It is subdivided into screw, rotary-plate, liquid-ring. The market is distinguished by a wide choice, providing rotary compressors. The device and their design are practically the same for all manufacturers or very similar. The pressure in them is reduced by the rotation of the screws.
The rotary-vane compressor isThe design in which the pressure is lowered due to the large rotor of the mold circumference. It rotates in a special round shape. Also in the rotor there are holes for rectangular blades. The design uses the principle of centrifugal force, rotating, the blades are pressed against the walls of the rotor.
The rotary screw compressor has a leading anddriven screw rotors. The main advantages of this compressor are high reliability, compact dimensions, small metal consumption. It provides a high speed of rotation of the rotors due to the absence of holes for the insert elements.
Rotary-piston compressors were the first inits kind of compressors. But this does not prevent and to this day be very popular in industrial enterprises. This design is very similar to the design of an internal combustion engine. The rotating element drives the piston, thereby compressing the air, reducing its pressure by several planes. The most trivial compressors have a single piston that is not capable of generating a lot of pressure.
Rotary-plate compressor - this compressor has a direct drive.It has a number of advantages: high reliability, high productivity, durability. The developed pressure of such compressors does not exceed 10 bar, has a small rotational speed, moderate power.
The rotary compressor of the air conditioner is built on the basis of a rotary compressor. In this case, compressors of small capacities are used. They are compact and practically do not make any noise.
Classification of compressors
- Compressor rotary air - this compressor compresses air with a pressure of 1.5 megapascals.
- The gas compressor is used for mixtures and gases, with the exception of hydrogen, and also oxygen.
- Circular - thanks to their device they are able to provide constant circulation in a confined space.
- Multifunctional special - the compressor rotor type is used.
Advantages and comparative advantages over an electric tool
In the electric tool, in fact, there is no motor. Therefore consumes more energy. Compressor rotary VR-type, in contrast to electricians, an order of magnitude safer.
The compressor is a versatile device in which you can connect other instruments. Also, the compressor has become more widespread, which means the approval of consumers.
Advantages of rotary compressors
The rotary compressor has several advantages:
- A simple design consisting of a small number of parts.
- Relatively small size, compactness.
- Reliability in use, basic preventive maintenance.
- Low final gas-dynamic losses due to the absence of valves.
Types of rotary compressors
Наиболее простой компрессор роторный – oil-free. This design does not have a lubricating structure, therefore it does not require the use of oils. This technological solution allows to reduce the cost of lubricants and maintenance, allows you to conduct a minimum number of scheduled services, as well as to receive compressed air without oil impurities and additives.
A more expensive alternative is the compressor.rotary oil with the presence of direct transmission. Their design provides a system for lubrication. And the drive and compressor head are connected by one shaft, which makes the transmission straight. An aluminum radiator is used to solve the cooling problem.
Similar to a piston diaphragm compressor.It differs from the piston in the presence of a membrane working surface. This membrane is made of durable and reliable materials that can withstand numerous translational-rotational movements. The change in air pressure occurs due to the oscillatory motion of the membrane.
There is also a more powerful compressor - withV-belt transmission. This means that the compressor head and the engine are connected with a belt. Cooling of such devices is much easier to organize, so they have a longer operating life. But the only downside is the high price.
Reviews of rotary compressors
First thing before buying, many people firstgo to the web pages in search of reviews about the product that they are going to buy. And this is correct, since it is better to learn from the mistakes of other people, weigh all the advantages and disadvantages and purchase a high-quality compressor.
Бывают очень дешевые роторные компрессоры, the cost of which varies from 300 to 500 rubles., but such devices suffice, at best, for several uses. Cheap compressors quickly overheat and become unsuitable, do not give the desired result.
In other cases, when purchased the originala compressor, the cost of which varies from 900 to 1,300 rubles, in 95% of cases, buyers were satisfied with the purchase. Such devices almost do not heat up, do not fail, give an excellent result when used.
Do not save on things that might becomeindispensable in your case. The best option would be to get a good, high-quality compressor that will last for a long time and will delight with its efficiency than acquire cheap ones that are almost disposable, losing nerves and precious time.
Based on a large number of reviews, you can make a list of parts that you should pay attention to when choosing and buying. These include:
- A compressor should have a supply wire of sufficient length, generally not less than 2 meters, since too short a wire can be inconvenient to use.
- The piston cylinder of a purchased compressor should not be made of aluminum alloys. The best choice would be stainless steel or high-alloy steel.
- Almost every compressor is equipped with a pressure gauge, but notAny gauge will be convenient. So, when using the compressor, the dial gauge will strongly deviate due to vibrations, which will create impossible conditions for the correct determination of pressure. Therefore, preference is given to digital pressure gauges.
- Piston rod must be installed directly on the steel shaft without adapters and plastic sleeves.
Conclusion
Buying a rotary compressor is importantHe needs to be taken seriously. The first thing to consider when buying a model from large and well-known manufacturers, as this will reduce the likelihood of poor quality products. Secondly, check the selected device for a fake case. Since often simple and reliable designs of large companies are easier to fake and pass off as original. Thirdly, choose a compressor that will suit you in its parameters. Fourth, check the compressor for the presence of a factory defect before paying. Fifthly, refer to the reviews for this model of rotary compressor online or offline, this will help to guard against errors already committed by someone.
