Compressor rotary: description and reviews

At present, the compressors have gained wide popularity. They provide overwhelming help 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 pumping gaming balls 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 implementation of the tasks. Therefore, it is important to choose the right compressor, as well as 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. The power and pressure force depend on the type and type of the device.

The rotor compressor, rotor-blade, rotary-screw, rotary-piston, rotor-air, rotor-plate type were especially popular. Each of them has unique characteristics and parameters.

Types of compressors

Compressor rotary is a device with a compressive rotating element. It is subdivided into screw, rotary-plate, liquid-ring. The market has a wide choice, providing rotary compressors. The device and its design are practically the same for all manufacturers or are very similar. The pressure in them is reduced by the rotation of the screws.

The rotary-vane compressor is a 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 and driven 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 have become the first of its kind 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, low-power compressors are used. They are compact and practically do not make any noise.

Classification of compressors

1. Compressor rotary air - this compressor compresses air with a pressure of 1.5 megapascals.
2. The gas compressor is used for mixtures and gases, with the exception of hydrogen, and also oxygen.
3. Circular - thanks to their device they are able to provide constant circulation in a confined space.
4. 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.

Compressor - a universal device, in which you can connect other tools. Also, the compressor has become more widespread, which means consumer approval.

Advantages of rotary compressors

The rotary compressor has several advantages:

• A simple design consisting of a small number of parts.
• Relatively small size, compact.
• Reliability in use, simple preventive maintenance.
• Low final gas-dynamic losses due to the absence of valves.

Types of rotary compressors

The simplest rotary compressor is 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 costs for lubricants and maintenance, allows you to conduct a minimum number of planned services, and also to get compressed air without oil impurities and additives at the outlet.

A more expensive alternative is a rotary oil compressor with the presence of direct transmission. Their design provides a system for lubrication. And the drive and the head of the compressor are connected by one shaft, which makes the transmission straight. To solve the problem with cooling, an aluminum radiator is used.

It is similar to the piston compressor membrane. It differs from the piston by the presence of a membrane working surface. This membrane is made of strong and reliable materials, which withstand many forward-rotational movements. The change in air pressure occurs due to the vibrational motion of the membrane.

There is also a more powerful compressor - with V-belt transmission. This means that the head of the compressor and the motor are connected by a belt. Cooling of such devices is much easier to organize, so they have a longer operating life. But the only drawback is the high price.

Reviews of rotary compressors

The first thing before buying many people first go to the Internet pages in search of feedback on the product that they are going to buy. And this is correct, because it is better to learn from the mistakes of other people, weigh all the advantages and disadvantages and purchase a quality compressor.

There are very cheap rotary compressors, the cost of which varies from 300 to 500 rubles. But such devices are sufficient at best for a few uses. Cheap compressors quickly overheat and become unusable, do not produce the desired result.

In other cases, when an original compressor was purchased, the price of which varies from 900 to 1300 rubles, buyers in 95% of cases were satisfied with the purchase. Such devices are almost not heated, do not fail, produce an excellent result when used.

Do not save on things that can become irreplaceable in your business. The best option is to get a good, high-quality compressor that will last a long time and will please with its efficiency, rather than buying cheap ones, which are almost one-time, losing nerves and precious time.

Based on a large number of reviews, you can make a list of details that you should pay attention to when choosing and buying. These include:

1. The compressor should have a power wire of sufficient length, generally not less than 2 meters, as too short a wire can cause inconvenience when used.
2. The reciprocating cylinder of the compressor to be purchased should not be made of aluminum alloys. The best choice is stainless steel or high-alloy steel.
3. Almost every compressor is equipped with a pressure gauge, but not every manometer will be convenient. So, when using a compressor, the pointer manometer will be strongly deflected due to vibrations, which will create impossible conditions for correct determination of pressure. Therefore, digital gauges are preferred.
4. The piston rod must be installed directly on the steel shaft without adapters and plastic sleeves.

Conclusion

Buying a rotary compressor is an important matter, it must be treated with all seriousness. 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 forgery. Since often simple and reliable designs of large companies are easier to counterfeit and give out for the original. Third, pick up a compressor that will suit you in its parameters. Fourth, check before paying for the compressor for factory marriages. Fifthly, refer to the reviews for this rotary compressor model online or offline, this will help to warn against errors already committed by someone.
