Currently, compressors have gained widespread popularity. They provide overwhelming assistance in solving everyday industrial or domestic problems.
Any industrial enterprise uses compressors to reduce energy 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 game balls and other inflatable products. Also, the farm can be useful for spraying water or solutions on plants, cleaning clogged pipeline communications. Rotary compressor can be useful in almost any branch of human activity. The performance of the tasks depends on its reliability and quality. Therefore, it is important to choose the right compressor, as well as to find out what you should pay attention to when buying.
Compressors
A compressor is a special device for supplying pressurized air to a pneumatic tool. At present, it is widely used in any human activity, even in art.
Compressor equipment is a device that produces excess pressure air. Power and pressure force depend on the type and type of device.
Rotary compressor, rotary vane, rotor-screw, rotary-piston, rotary-air, rotary vane are especially popular. Each of them has unique characteristics and parameters.
Types of Compressors
A rotary compressor is a device with a compressing rotating element. It is subdivided into screw, rotor-lamellar, liquid-ring. The market has a wide selection, providing rotary compressors. The device and their design in almost all manufacturers are the same or very similar. The pressure in them decreases due to the rotation of the screws.
A rotary vane compressor is a structure in which pressure is reduced due to a large circular rotor. It rotates in a special round shape. Also, holes for rectangular vanes are provided in the rotor. 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 great reliability, compact size, small metal consumption. It provides a high speed of rotation of the rotors due to the absence of holes for insertion elements.
Rotary piston compressors are the first of its kind to be compressors. But this does not prevent 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, lowering its pressure in several planes. The most trivial compressors have a single piston, not able to create a lot of pressure.
Rotary vane compressor - This compressor has a direct drive. It has a number of advantages: high reliability, high performance, durability. The generated pressure of such compressors does not exceed 10 bar, has a small rotational speed, moderate power.
The rotary compressor of the air conditioner is based on a rotary compressor. In this case, low power compressors are used. They are compact and practically do not make any noise.
Compressor classification
- Rotary air compressor - this compressor compresses air with a pressure of 1.5 megapascals.
- A gas compressor is used for mixtures and gases, with the exception of hydrogen as well as oxygen.
- Circular - thanks to their device they are able to provide constant circulation in a closed room.
- Multifunctional special - at the base is used a rotary type compressor.
Advantages and comparative advantages over an electric tool
In an electric tool, in fact, there is no motor. Therefore, it consumes more energy. Compressor rotary BP-type, unlike electricians, is much safer.
A compressor is a universal device into which other tools can be connected. Also, the compressor has become more widespread, which means consumer approval.
Benefits of Rotary Compressors
Rotary compressor has several advantages:
- Simple structure consisting of a small number of parts.
- Relatively small dimensions, compactness.
- Reliability in use, basic preventive maintenance.
- Low final gas-dynamic losses due to the lack of valves.
Types of Rotary Compressors
The simplest rotary compressor is oil-free. This design does not have a lubricating structure, therefore, does not require the use of oils. This technological solution allows you to reduce the cost of lubricants and maintenance, allows you to carry out a minimum number of scheduled maintenance, as well as receive compressed air at the outlet without oil impurities and additives.
A more expensive alternative is a rotary oil compressor with direct transmission. Their design provides for a lubrication system. And the drive and compressor head are connected by one shaft, which makes the transmission direct. To solve the problem with cooling, an aluminum radiator is used.
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 withstand numerous translational-rotational movements. The change in air pressure occurs due to the oscillatory movement of the membrane.
There is also a more powerful compressor - with V-belt drive. This means that the compressor head and engine are connected by a belt. The cooling of such devices is much easier to organize, so they have a longer service life. But the only drawback is the high price.
Rotary Compressor Reviews
The first thing before buying, many people first go to the Internet pages in search of reviews about the product they are going to buy. And this is correct, since it is better to learn from the mistakes of other people, to weigh all the advantages and disadvantages, and purchase a high-quality compressor.
There are very cheap rotary compressors, the cost of which varies from 300 to 500 rubles, but such devices are enough at best for several uses. Cheap compressors quickly overheat and become unusable, do not give the desired result.
In other cases, when an original compressor was purchased, the cost of which varies from 900 to 1300 rubles, buyers in 95% of cases 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 can become indispensable in your business. The best option would be to purchase a good, high-quality compressor that will last a long time and will delight you with its performance than to purchase cheap ones that are almost disposable, losing your 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:
- The compressor must have a power wire of sufficient length, in general not less than 2 meters, since too short a wire can be inconvenient to use.
- The piston cylinder of the compressor purchased must 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 not every pressure gauge will be convenient. So, when using a compressor, the gauge will deviate greatly due to vibration, which will create impossible conditions for the correct determination of pressure. Therefore, preference is given to digital pressure gauges.
- The piston rod must be installed directly on the steel shaft without adapters and bushings made of plastic.
Conclusion
Buying a rotary compressor is an important matter, it must 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 in case of fakes. Since often simple and reliable designs of large companies are easier to fake and pass off as the original. Thirdly, choose a compressor that will suit you in terms of its parameters. Fourth, check the compressor for factory defects before paying. Fifth, refer to the reviews on this rotary compressor model online or offline, this will help to prevent mistakes made by someone else.
