Oil compressors represent one of the most popular types of piston mini-stations. Their popularity is due not to high performance and wide functionality, but to the balance of various operational parameters. In particular, the combination of modern ergonomics and versatility in terms of connecting to different equipment makes a piston oil compressor in demand among automobile masters. They also use such installations in households - the affordable price and small dimensions make such acquisitions the most profitable.
Appointment of the unit
The main function that reciprocating compressors perform is to supply compressed air at certain pressure and power ratings. The most widespread use of such devices is in workshops where paint work is required. To implement such measures, the piston oil compressor is connected to a special apparatus that provides spraying of the paintwork composition. In small car services, for example, a combination with spray guns is used, and in large industries, the compressor can work together with professional installations working with abrasive substances.
Another common operation for which such equipment is used is air pumping. Again, depending on the scope, it can be a bicycle tire or an inflatable boat. In accordance with the requirements for air volume and feed force, an oil compressor is also selected in one version or another. Less common are procedures associated with the technological purging of locks, engines, and various mechanisms.
Device and principle of operation
Oil compressors can have one or two cylinders, in which the basic functional operations occur, ensuring the supply of the working mixture. Two-cylinder models are considered more productive, since they assume the simultaneous operation of two piston mechanisms. At the same time, an oil compressor in this design requires more attention in maintenance. Such measures are associated with replacing filters and cleaning the cylinders of oil impurities. Compressed air accumulates in the receiver, during which condensation develops. Excess moisture must be removed manually or automatically using a special system. Complete condensate elimination, for example, is possible provided that special dehumidifiers are used. Also, on compressor housings of this type, manufacturers include pressure regulators and manometers.
Performance data
Largely due to the balanced technical parameters, this type of compressor has become widespread. Not the main, but the basic operating parameter that can affect other characteristics is power. It varies in oil models on average from 1,500 to 2,200 watts. Power is reinforced by pressure - for small household operations 6 Bar is enough, but tasks of medium complexity require a potential of 8-10 Bar. Also, the oil compressor is equipped with a receiver, the capacity of which can be 25-200 liters. Together, the listed parameters determine the most important characteristic in terms of practical use - performance. This indicator varies from 200 to 400 l / min. However, professional models provide more than 500 l / min.
Varieties
In this category, several types of compressors are distinguished, among which belt and coaxial models deserve attention. They can be attributed to traditional oil-type models only conditionally, but they constitute quite serious competition. So, if you need to work with a pneumatic tool, then an oil coaxial compressor will be the best option. The advantages of such units include modest dimensions, the possibility of automatic lubrication and additional equipment with auxiliary equipment.
Ordinary users often have to choose between low-power household and expensive professional models. The former are convenient, but do not always meet operational requirements, while the latter provide ultra-high performance, but are inconvenient in maintenance. As an intermediate option, it is worth considering an oil belt compressor , which is characterized by durability, small size and power sufficient for average needs. True, a belt drive enhances the noise level of the unit and the vibration effect.
Manufacturer's Reviews
Users highly appreciate the work of compressors of well-known brands, including Fubag, Metabo, Patriot, etc. As operating practice shows, their reliable assembly withstands the most severe operating conditions, and ergonomic devices facilitate the operator's function. In the middle niche, lesser-known firms are represented, such as Kaeser, Remeza and Fiac. In the families of these companies you can find an affordable oil compressor, which also will not disappoint during use. According to the criteria of performance and reliability, users respond quite well to domestic products. For example, high-quality compressors are produced under the brands Energomash, Prorab and Caliber.
Conclusion
The operation of compressor stations in most cases involves auxiliary accessories. This group of devices includes adapters, couplings, hoses for supplying working fluids and other accessories. Typically, an air-oil compressor is supplied with sets of similar devices, but non-standard fittings may be required to perform highly specialized tasks. In addition, work with a pneumatic tool is strictly regulated by safety requirements. This also applies to the performance of paint operations, and especially the processes of spraying abrasive substances, during which the use of goggles and gloves is mandatory.
