High-speed Water Jet Nozzle Metal Injection Molding Process MIM Parts

Water jet technology is a high-tech that is booming and has a wide range of uses. Water jet technology is also called hydraulic jet technology. It mainly uses water as a medium. After obtaining huge energy through a high-pressure generating device, it is ejected from a nozzle of a certain shape at high speed in a specific fluid motion mode. A highly concentrated stream of water.

According to its characteristics, water jets can be divided into the following types:

① Continuous water jet:

This is the most common and most common water jet. It is a water stream ejected from the nozzle at a high speed and at a constant speed. The impact of water jets on materials can achieve the purpose of industrial application. The main means to improve its working efficiency is to increase its working pressure.

② Pulsed water jet:

The continuous jet is divided into a series of discontinuous jet segments, and the jet formed in this way is a pulsed water jet. This jet gives full play to the striking ability of the jet, reduces the specific energy consumption rate, and improves work efficiency. According to the different forms of partition, pulsed water jets can be divided into: blocking pulsed water jets, excitation pulsed water jets and extrusion pulsed water jets.

1) Blocked pulse water jet is to use a jet interrupter to divide the continuous water jet into a series of discontinuous jet segments.

2) Excitation pulse water jet is a pulse jet generated by adjusting the internal structure of the continuous jet using fluid mechanics and transient flow theory to make the jet energy change periodically.

3) Extrusion impact pulse water jet is a pulse water jet obtained by using electrical energy, gunpowder explosion energy, special compound deflagration energy and gas compression energy as power sources, and transmitting energy to the working medium in a very short time through a certain device.

③ Cavitation water jet

It is generally believed that when the local absolute pressure of water at a certain point in the high-pressure flow reaches the saturated vapor pressure at the local temperature, the air dissolved in the water will be released to form many cavitations, and the collapse of the cavitation will cause huge hydraulic shock. Cavitation jet uses the huge impact force caused by the collapse of cavitation to enhance its effect.

④ Abrasive water jet

Abrasive, various additives and water are prepared into a slurry (non-Newtonian fluid) in advance, and the jet formed by the high-pressure pump through the nozzle is called an abrasive water jet. Abrasive water jet can change the original water jet's impact and deformation effect on the material into a high-frequency impact and grinding effect of abrasive particles on the material, greatly improving the working efficiency of the water jet.

In addition, according to specific application needs and research analysis, there are also high-temperature jets, swing jets, rotating jets, etc.
