1. Selection of zero nozzles
 
Zero nozzles are mainly used for cleaning with small surface areas, deep holes or grooves. The water emitted from the zero nozzle is linear, and the pressure is relatively concentrated. When matching, its aperture, material and thread interface are complete in accordance with the company's equipment configuration list.

 
2. Fan nozzle selection
 
The fan-shaped nozzle produces a flat and average jet directly from the shape of the nozzle, and its jet density is better. The Angle of diffusion can also vary over a large range at present. We use fan nozzles: 15 degrees, 25 degrees, 45 degrees and so on. Mainly used for washing, spraying, cooling and exterior cleaning. The selection is based on the detailed technical parameters of the equipment, according to the company's equipment configuration list.

 
3. Selection of pipe cleaning nozzle
 
Usually, the outside diameter of the cleaning nozzle is less than the inside diameter of the pipe, but not less than 20 mm. The pipe with a large diameter can not choose to clean the nozzle, then it is necessary to choose the water mine to stop the operation! The number of nozzle holes and radiation Angle can be determined according to the working condition.

According to practical experience, it does not make much sense to choose a nozzle with a hole after the first hole. Select a post-porous nozzle. When using a steel gun, the cleaning nozzle can not be selected after the opening of the nozzle, to select the front porous nozzle. When there is heavy oil dirt in the cleaning pipeline, it is necessary to consider the choice of rotary pipe cleaning nozzle.
