This helps to select the nozzles. The 110 refers to the fan angle (110°) and the 04 refers to the flow rate. Each nozzle brand has a slightly different convention, but no matter how the information is presented, it must be somewhere on the nozzle. The first two numbers are the spray pattern, i.e.The second two numbers are the size of the hole, so an xx40 tip is a hole size of 4.0.
You can check this chart to see what hole size affects your psi. You usually try to match the hole size to your machine's gallons per minute. The nozzles you use in your pressure washer come in two different sizes. It has a measurement in one direction and a measurement in the other direction.
The first is the one that measures the size of a fan-shaped sprayer, that is, a 0-degree pin-tip sprayer, a 15-degree fan sprayer, a 25-degree fan sprayer, a 40-degree fan sprayer, etc. This is the size you're familiar with and the first 3 numbers on the nozzle represent these measurements. The second measurement is better described as the width of those aerosols. The last 3 numbers of the nozzle indicate this measurement; for example, 040, 045, 050 are all the measurements of the nozzle in this way.
This nozzle measurement matches your machine's PSI and GPM and is adjusted accordingly. Therefore, every time you ask us for nozzles, we look for the type of machine you have in our records or we ask you what the PSI and GPM of your machine are. There are usually four or five numbers stamped on a mouthpiece. The first two digits usually identify the angle or degree of the spray pattern.
The last one or two digits of a nozzle indicate the size of the hole (opening) through which the fluid must pass. If the number ends in 35, that indicates that the nozzle size is 3.5, for example. It is necessary to overlap the flat fan nozzles because the outer edges of the spray patterns have conical or small volumes. The most uniform pattern is achieved when this overlap is 50 to 60 percent of the space between the nozzles (Figure.
Table 1 lists the suggested nozzle heights for the different spray angles. Check for spray overlap by spraying clean water onto a flat surface (concrete) and observing drying patterns. Because of their ability to produce a very uniform pattern when properly superimposed, flat fan-shaped nozzles are often the best choice for widespread herbicide application. The pump itself could also be damaged if too much pressure builds up repeatedly due to the use of the wrong nozzle, putting pressure on the motor and causing it to fail prematurely.
At these pressures, this type of nozzle produces medium to thick droplets that are not as susceptible to drift as the finer droplets produced at pressures of 40 psi or more. Pre-orifice nozzles with drift reduction produce a standard flat fan pattern and, at the same time, effectively reduce the outlet pressure in the nozzle. At pressures of 40 to 80 psi, these nozzles produce small droplets that easily penetrate plant tops and cover the underside of leaves more effectively than any other type of mouthpiece. A spray nozzle table provides all the information needed to determine the performance of a nozzle under different operating pressures.
A spray nozzle that produces a burst that is too powerful could remove paint from surfaces, damage the mortar, or cause fluids to settle on the coating or tiles, which could damage water.
