The washing high-pressure apparatuses
Recently the letter from the reader afflicted with purchase has come to edition. For 700 rubles it has purchased as writes, the “wonderful device” capable, according to the producer, to wash the car a water stream pressure of 0,1–0,2 atm even from a liter plastic bottle. Only be connected to the lighter — and an order.
If you were interested in such sink too, let’s not hurry. At first we will look how more serious devices intended for this purpose are arranged, having paid attention at least to such indicators as pressure, power consumption and a consumption of water. Then we will already make the decision …
This overview is devoted to high-pressure apparatuses. Personally they can be seen on any paid manual car wash. The principle of work of “washermen” is simple. In the beginning dirt is forced down a powerful stream of the water created by such device, then the machine is washed with a sponge with shampoo, and then wash away foam. After such handling the car is wiped dry — and all are happy. However, recently there was also a bit different, more perfect technology of a sink, but … about it a bit later.
We will make a reservation: to tie purpose of high-pressure apparatuses only to a car sink not absolutely correctly. The most part of buyers of household and semi-professional mini-sinks (between them there is no clear boundary) are owners of dachas and country houses who wash not only machines, but also paths, facades, pools, garden furniture — yes you never know still? And here so-called professional devices serve rather for business — targeting of “marafet” at the entities, in shops and besides for car washes.
Today the prices of the simplest high-pressure apparatuses fluctuate near a mark of 100 dollars. For this money producers will offer the most unpretentious and modest devices of a household series. Unlike professional and semi-professional sinks, they are not expected prolonged continuous use, cannot brag of stunning performance and the created pressure (which value usually bring in liters/hour and bars, respectively). Work from a network of 220 V and consume approximately from one and a half kilowatts and more. A water intake — first of all from a water supply system though many models are expected a simple hose and a bucket with water. But convenience of use of such “technology” will be minimum. The air which has accidentally got to a hose will break stability of work not to mention that will damage to the device. And one bucket of water, most likely, not to manage: it is necessary to be interrupted several times — not really conveniently. But if to lift reservoir with water on the small height (at summer residents it is usually reduced to a pathos barrel), then it is possible to have pressure of water, already sufficient for giving, and to forget about everything the inconveniences noted above.

The price dispersion on these products is very big, and involuntarily there is a question: than expensive it is better than “prostachok” and in what fundamental differences between household, professional and semi-professional devices?
We will begin with simple. It is clear, that to bring down dirt a strong pressure and a large amount of water much easier and quicker. Such characteristics as pressure and consumption of water, here main, though not unique. The emphasis only on indicators of the maximum pressure is incorrect: performance is important in not smaller degree. Moreover, sometimes specify the maximum pressure measured in case of not pressed lever of the gun or when using special nozzles, and it not the same that pressure during the work. Besides, cheap mini-sinks imply availability in a design of less durable and strong nodes.
It is worth paying attention to engine type. In expensive models it is so-called asynchronous: it is easy to distinguish it as on a characteristic sound (it less shrill and buzzing), and on sink weight (on average more than 7 kg). In cheap options — unpretentious high-speed cursors with reducers. The “trifles” increasing service life — shutdown when release the gun lever, more perfect filtering water, etc., besides, are provided in devices more seriously.
Convenience — the important factor influencing duration of a sink and its quality. Upon purchase pay attention to length of a hose of a high pressure, ease of its connection, noise level, and also to the regulator of pressure and a form of a stream, castors and even the handle for transfer (that it is easier: to carry the 15-kilogram device or to carry?). We will mention nozzles: various brushes, mud mills, etc. They can be delivered both in a set, and as additional equipment. The main thing not to lose sight of compatibility.
We will note also that among expensive devices there are also autonomous, working at gasoline, and even devices with heating of water.

Recently the increasing popularity is gained by foam cleaning, or as it is called still, contactless washing. The main advantage is emphasized in the name — contactless. The essence of process is reduced to the fact that special foam is applied directly on the contaminated car, and delete it with water. No manipulations with a sponge and shampoo are required. Also the saving of time is available. But the “real” contactless washing requires expensive device with penokomplekty and a special injector which creates abundant foam.
There is also simpler option with use of cheap high-pressure apparatuses. Almost all of them are capable to spray both shampoo, and other “chemistry”, but, unfortunately, because of a different way of mixing (with water, but not air!) abundant foam will not turn out.
Sinks of a high pressure first of all can attract the motorists having the houses and dachas. Upon purchase pay attention to a complete set nozzles or a possibility of retrofitting by them. It is worth being defined at once whether you will resort to full foam cleaning. If yes, that the cost of such device considerably increases and, besides, it is possible, it is necessary to buy in addition пенокомплект. Any washing requires water, or rather system of its giving — be ready to it.
And the last. A stream of a pressured water — not a joke. It cannot be directed to people, animals and brittle things closely. So before use attentively study the instruction.
