Waterjet Nozzle 8.0x1.02x101.6 mm 307651-042 OM-A

About waterjet nozzles

Waterjet nozzles are mainly installed on waterjet cutting machines, which can cut metal, ceramics, stone, glass and other materials. We have a complete research and development, production, after-sales and domestic and foreign sales centers to ensure that every waterjet nozzles produced has undergone professional quality inspection procedures, and we are committed to becoming your reliable choice.

Our waterjet nozzle have the following characteristics

1. Excellent wear resistance

Our waterjet nozzles use high-quality cemented carbide bar production line, with the highest density and hardness of binder-free carbonization and powder-free, strong resistance to abrasion and corrosive wear so that waterjet nozzles have excellent wear resistance and ensure waterjet machine Service life.

2. Higher accuracy

The product line of waterjet nozzles is produced using centerless grinding, wire cutting, laser etching and electric pulse machines to ensure the accuracy and smoothness of waterjet nozzles.

Our waterjet nozzles are suitable for all modern cutting head systems. Excellent wear resistance and higher accuracy also mean higher dimensional accuracy and the ability to perform the longer uninterrupted cutting. These processes ensure a more cost-effective Cutting work.

As a waterjet nozzles manufacturer and supplier, we provide OEM and ODM services, so you can sell waterjet nozzles under your brand.

The installation of waterjet nozzles and waterjet orifices

How to install the waterjet nozzles and waterjet orifices after we get them?Let's explain the considerations and operation methods in detail.

1, First of all, it is necessary to ensure that the working surface of the orifice seat and the jacket of the waterjet mixing tube is clean and without dust.

2, Install the orifice to test the straight line of the water column, and then install the waterjet mixing tube;

3, Test with low pressure water without sand , until the ejected water column is in a straight line without scattering, proving that the waterjet nozzle and the waterjet orifice are absolutely concentric then add sand and pressing for normal cutting.If the jet of water does not appear in a straight line,then need to re-install, twist, or replace the orifies.

4, After every 10-20 hours of using the waterjet nozzles, please rotate it to 120 degrees.

The above operation can ensure the service life of waterjet focusing tube to a large extent.The installation method of waterjet focusing tube an waterjet orifices is not so difficult. If the waterjet spare parts are damaged, you can buy from us and replace them by ourselves. This will reduce unnecessary on-site costs for you . To know know waterjet cutting spare parts? Pls CONTACT US right now! Foshan HaiRan Waterjet Spare Parts Team will offer you the professinal waterjet cutting spare parts service.

Related Knowledge Of Waterjet Nozzle/Mixing Tube/Focusing Tube

Waterjet Nozzle/Mixing Tube/Focusing Tube , refers to the high pressure waterjet cutting machine outlet used as abrasive and water mixing. Because of the harsh environment of the internal jet flow, the abrasion of the waterjet mixing tube is very great after the abrasive is accelerated, so it is necessary to use very wear-resistant materials for manufacturing.Waterjet focusing tube is the key of abrasive jet.For a long time, the high pressure abrasive jet nozzle has been perplexed by the water jet field in China. Up to now, the service life of the waterjet mixing tube for cutting and the pre-mixed abrasive jet nozzle has not been satisfied. Water jet focusing tube is a very important accessory of waterjet cutting, it determines the function of water jet cutting. 

1. Installation steps of sand mixing pipe

In order to ensure the normal use of the sand mixing pipe, please install it in strict accordance with the following steps

1. Ensure that the gemstone nozzle seat and the working surface of the sand mixing pipe jacket are clean and free of sand;

2. Install the orifice to test the straight line of the water column, and then install the sand mixing pipe;

3. Debug with low-pressure sand-free water until the sprayed water column is in a straight line without scattering, which proves that the sand mixing tube and the gemstone nozzle are absolutely concentric before adding sand and pressurizing the normal cutting;

4. After using the sand mixer for 10-20 hours, please rotate the sand tube 120 degrees.

The above steps can ensure the service life of the sand pipe to a greater extent.

2. Factors affecting the life of waterjet abrasive nozzle

1. The optimal  proportion of the inner diameter of nozzle and orifice, the best proportion is 1:3.

For example: the inner diameter of the waterjet nozzle is 1.0mm, then the inner diameter of the ruby orifice should be 0.33mm. This ratio has been tested a lot, the cutting is the most powerful, and the mixing tube wall wear is the least; (Note: If the pressure and flow cannot reach If so, take a smaller orifice)

2. The particle size and quality of the sand, too coarse and impurity sand will accelerate the wear of the focusing mixing pipe;

3. Dirty, hard, and insufficiently filtered water can easily destroy the ruby orifice under ultra-high pressure, and the sprayed water will scatter and quickly damage the inner wall of the abrasive nozzle;

4. The main influencing factor is the concentricity of the orifice and the sand mixing tube.

Even a slight difference in the concentricity will cause the sand and water to deflect and then hit the inner wall of the water jet nozzle, and cause rapid wearing, as well as it leads to poor cutting and slow speed.

Note: Please check whether the inner wall of the cutting nozzle is smooth before use. If it is not smooth, please contact us immediately for replacement;

Normally the performance of the nozzle is affected by the below factors:

1. Poor water quality causes abnormal damage to orifice, thus damaging the cutting mixing tube;

2. The design of the water jet orifice or the combination of the orifice seat is not good, and the water arrow is not normal;

3. The orifice seat has been worn out, causing turbulence, and the water arrows are not concentrated;

4. The design and working accuracy of the cutting head are poor, and the cutting orifice still has displacement before and after each installation, causing the center of the water arrow to be incorrect;

5. The sand-water mixing space is poorly designed, causing turbulence;

6. The design of the cutting head is poor, and the force when the gem seat is fixed is different, which causes the direction of the water arrow to shift and damage the sand pipe;

7. The steel and crafts used for the cutting head or gem seat are not up to standard, which makes the accuracy change rapidly and causes the water arrow to drift.
