The compressor oil piston

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 the piston oil compressor in demand among automotive masters. Use such facilities in the domestic economy - affordable price and small dimensions make such purchases the most profitable.

Purpose 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 in workshops where paintwork is required. To implement such measures, the piston oil compressor is connected to a special apparatus that provides spraying of paint and varnish composition. In small car-care centers, for example, a combination with spray guns is used, and in large plants it is also possible to work together with professional installations that work with abrasive substances.

Another common operation for which such equipment is used is air pumping. Again, depending on the field of application, it can be a bicycle tire, and an inflatable boat. In accordance with the requirements for the volume of air and the power of the feed, an oil compressor is selected in this or that modification. Less common procedures associated with the technological blowing of locks, engines and various mechanisms.

The device and the principle of operation

Oil compressors can have one or two cylinders, in which the main functional operations that provide the supply of the working mixture take place. Two-cylinder models are considered to be more productive, since they presuppose 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 the replacement of filters and cleaning of the cylinders of oil impurities. The compressed air accumulates in the receiver , during which the condensate is released. Surpluses of formed moisture must be removed manually or automatically by means of a special system. Complete liquidation of the condensate, for example, is possible with the use of special dehumidifiers. Also on the cases of compressors of this type manufacturers provide pressure regulators and pressure gauges.

Performance Characteristics

In many respects due to balanced technical parameters, this type of compressors has become widespread. Not the main, but the basic operating parameter, which can affect other characteristics, is power. It varies among oil models on average from 1500 to 2200 watts. The power is reinforced with pressure - 6 bars are enough for small household operations, but the tasks of an average level of complexity require a capacity of 8-10 bar. Also, the oil compressor is supplied with a receiver, the capacity of which can be 25-200 liters. Together, these parameters determine the most important performance characteristic in terms of practical use. This figure 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 attention deserves the belt and coaxial models. To conventional oil-type models, they can be attributed only conditionally, but they constitute quite a serious competition. So, if you want to work with a pneumatic tool, then the 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.

Before ordinary users, there is often a choice between low-power household and expensive professional models. The first is convenient, but does not always meet the performance requirements, while the latter provide ultra-high performance, but inconvenient in content. As an intermediate option is to consider a belt oil compressor , which is distinguished by its durability, small dimensions and sufficient for medium-sized capacity. True, belt drive increases the noise level of the unit and the vibrating effect.

Reviews of manufacturers

Users appreciate the work of compressors of famous brands, including Fubag, Metabo, Patriot, etc. As practice shows, their reliable assembly withstands the most stringent working conditions, and ergonomic devices facilitate the operator's function. In the middle niche there are less well-known companies such as Kaeser, Remeza and Fiac. In the families of these companies, you can find an affordable compressor oil, which also does not disappoint in the process of use. In terms of performance and reliability, users respond well to domestic products. For example, high-quality compressors are produced under the brands "Energomash", "Foreman" and "Caliber".

Conclusion

The process of operation of compressor stations in most cases involves and auxiliary accessories. This group of devices includes adapters, couplings, hoses for supplying working media and other additions. Usually 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, working with a pneumatic tool is tightly regulated by safety requirements. This applies to the execution of paint operations, and especially the processes of spraying abrasive substances, during which it is mandatory to use protective glasses and gloves.
