Water Jet focusing tube profile
Water Jet focusing tube, also called sand pipe, abrasive nozzle, water nozzle, water cutter, water cutter sand pipe, water jet nozzle, mainly used for metal cutting, ceramic cutting, stone cutting, glass cutting and other material cutting. Water Jet focusing tube refers to the nozzle used for mixing abrasive and water at the outlet of high pressure abrasive water jet machining machine. Water cutting principle is to use high pressure technology to pressure the ordinary tap water to 250~400Mpa pressure, and then through the inner hole diameter of 0.15~0.35mm gem nozzle jet formation speed of about 800~1000m/s high-speed jet, commonly known as the water arrow, the water arrow has a high energy, can be used to cut soft base materials. If the right amount of abrasive is added to the water arrow, it can be used to cut almost all soft and hard materials. Adjust the pressure and flow of water jet, you can use it to clean all kinds of objects, such as glue removal, paint removal, rust removal, we can also use high pressure technology for autoclaving, food preservation and many other beneficial to human work.
Characteristics of sand pipe:
The sand tube is perforated by electric spark and finely ground by slow wire, which has good abrasion resistance and precision machining accuracy.
Water Jet focusing tube material description
Water Jet focusing tube is scoured by high-speed abrasive particles, because of the adverse internal jet conditions and environment, the abrasive is accelerated to wear very large inside the sand tube, so it is necessary to use very wear-resistant materials to manufacture, its material selection is very important. Generally speaking, sand tube material must have high hardness, high wear resistance, both are short of one cannot. It is generally made of composite tungsten carbide materials. Generally, WC as the main wear phase exists in the form of particles, CO only as a binder and cobalt content is less than 0.6%, density 15.45g/cm3~15.6g/cm3, flexure 2000MPa~2400 MPa. Vickers hardness is higher than 2700HV. Small thermal expansion coefficient, high hardness and density, strong oxidation resistance, greatly beyond other similar products,
Shape and characteristics of Water Jet focusing tube:
Water Jet focusing tube structure is very simple, basically consists of two sections: cone inlet and cylindrical outlet. Its size is slightly different for different uses.
Water Jet focusing tube use range:
Widely used in various types of machines, WHP, FLOW, JET, KMT, OMAX, WS.
Precautions for the use of Water Jet focusing tube:
If the nozzle is not aligned with the sand pipe, it will cause premature wear of the sand pipe. In order to prolong the service life of the sand pipe, the water should be aligned with the sand pipe before use to ensure that the water flow is in the central position. Rotation of sand tube 120 degrees also increases centripetal wear.
The use of Water Jet focusing tube should pay attention to the following three problems:
1) Whether the gem (diamond) nozzle and Water Jet focusing tube are aligned.
2) Check the new gem (diamond) nozzle for notches.
3) Wear and tear appears in the sand mixing chamber.
If the jet is not aligned, it will directly impact the inner wall of the sand pipe, resulting in a decrease in cutting speed and a sharp shortening of the service life of the sand pipe. The normal sand tube wear shows a continuous and continuous wavy wear pattern from the inlet to the outlet.
Excellent abrasion resistance of sand tube:
Hardness HV10 acuity 2860 hv
Strength is 1000 mpa
In general, the use time of Water Jet focusing tube water cutting (slightly different according to the specific working condition) :
400 mpa - 100-120 hours
280 ~ 300 mpa - 150-200 hours
About 200Mpa ----- over 300 hours
The service life of Water Jet focusing tube depends on the material of the product itself, and is closely related to the pressure of water knife equipment, the use of abrasive, abrasive material, hardness and so on.
Our sand pipe advantages:
1.100% raw material, provides titanium tantalum coating for increased wear resistance.
2. The outer diameter specifications are φ 6.35, φ 7.14, φ 7.6, φ 9.45.
3. Unbonded tungsten carbide special material, long service life, hardness up to 96.5HRA, good wear resistance. Quality stability is fully guaranteed, this kind of products are rare domestic manufacturers of reliable quality.
4. We can produce the size as required.
