Nozzles, spears, washing pistols and other high-pressure water cleaning accessories are selected taking into account the parameters of the high-pressure apparatus with which they will work. The choice of the nozzle should be carried out by a specialist in accordance with the maximum operating parameters of the high-pressure pump. The more correctly the selection of attachments is made, the more qualitative the results of washing will be. Incorrect selection of working attachments will lead to a decrease in the operating parameters of the apparatus, rapid wear of its components, or may lead to its failure. The nozzles and nozzles with the right selection will provide the most effective way to clean the surface.
Enhancement of the detergent effect can be achieved by changing the spraying angle of the jet or, for example, rotating the jet under pressure. To remove paint or rust from the surface, a sandblasting nozzle can be used, which adds quartz sand to a stream of high-pressure water.
The shape of the surface, its accessibility for washing, must be taken into account when selecting special auxiliary nozzles, nozzles and devices that ensure high-quality washing of hard-to-reach places, for example, the bottom and arches of the car, tanks, pipes, channels, tanks, where it is necessary to wash not only the external but also the inner surface . Rotating heads and nozzles with different number and direction of detergent nozzles can be used for these tasks.
An important addition is the possibility of using a detergent or disinfectant, dosed at a certain concentration through special injection devices. The novelty is an injector using compressed air and high-pressure water, which forms an active foam. Washing and disinfection of equipment and work surfaces with high foam means is increasingly used in the food industry.
High pressure coils with automatic hose inspection provide extra comfort in work, careful storage of hoses. The design of the stainless steel coil provides the possibility of their use in the food industry, significantly increasing the service life. Coils can be supplied with hoses of different length and diameter, working pressure.
