Water jet nozzle design. Figure 3 orifice selection chart general pump selection guidelines. It s the amount of water and the pressure that is demanding the horsepower wirtanen agrees stating that if you were to use the same orifice nozzle combination the same amount of abrasive and the same volume of water 90 000 psi will still outperform 60 000 psi every time. For free gas atomization fig. 4 3 in this atomizer the liquid metal issues in the form of a stream from a.

The next step in determining which pump is appropriate for your application is to determine the types of material you will be cutting and how many cutting heads you want to be able to run at one time. Engineers design nozzles with different spray distribution patterns. Depending on the tilt of the pipe end the water jet rises vertically or forms a parabola. They are classified as free fall confined or closed nozzles fig.

The solid water jet nozzle was the first cone nozzle to appear in history and at first was the simple pipe end that we mentioned in the first article of this blog through which water was discharged at a certain pressure fig. Smith s design was further refined by leslie tirrell of the hydroblast corporation in 1937 resulting in a nozzle design that created a mix of high pressure water and abrasive for the purpose of wet blasting. Many gas atomizer designs are known. A large number of tests show that the diameter of the abrasive jet nozzle should be slightly larger than that of the water jet.

4 25 a the key process variables are similar to those of water atomization fig. The impact force is the force generated by the jet of water deflected by the impact surface and its strength is often expressed in kg cm2 or lb inch2. Nozzles h2o jet manufactures the advantage water jet pumps and waterjet parts and aftermarket water cutting parts compatible with the flow water jet pump. 4 25 and internal mixing the closed nozzle designs are also called close coupled nozzle designs.

The diameter of the abrasive jet nozzle is related to the diameter of the water jet nozzle and the distance between the abrasive jet nozzle and the water jet nozzle. A water jet cutter also known as a water jet or waterjet. A gas jet fluid jet or hydro jet is a nozzle intended to eject gas or fluid in a coherent stream into a surrounding medium. D d.
