FAQ of the waterjet cutting nozzle/nozzle/mixing tube:

How should we choose the right waterjet mixing tube/nozzle/focusing tube? The inner hole of the waterjet nozzle is generally 1.02 mm. The material of the nozzle must have high hardness and high wear resistance, and it is generally a composite tungsten carbide material.

When choosing a water jet mixing tube, you need to pay attention to the following points: ·According to the thickness and hardness of the cutting material, choose the appropriate mixing tube diameter and length, generally speaking, the smaller the diameter, the longer the length, the faster the cutting speed, but the worse the durability. ·

According to the brand and model of the cutting machine, select the matching water jet mixing tube specification and interface to avoid unstable installation or water leakage. ·

According to the frequency of use and the environment of the cutting machine, replace the mixing tube regularly, check whether there are cracks or wear inside the mixing tube, so as to prevent the cutting quality from being affected or potential safety hazards caused.

Choose quality-assured water jet cutting nozzle products produced by regular manufacturers, and avoid using inferior or counterfeit mixing tubes, which may cause loss or harm

What is the reason for the backwater of the waterjet mixing tube/waterjet cutting nozzle/focusing tube, and how to solve this problem?

Water jet mixing tube backwater refers to the phenomenon that water flows back to the waterjet cutting nozzle from the outlet direction of the mixing tube during the water jet cutting process. This phenomenon will affect the cutting effect and life of the water jet, and even damage other related accessories of the water jet. .

The reasons for waterjet cutting nozzle backwater may be as follows:

The mixing tube is blocked, it may be because the pomegranate sand is not pure enough, there are large particles or impurities in it, or because the mixing tube is aging, cracks or deformation appear.

The water switch fails, it may be because the seal of the water switch is damaged, or the solenoid valve of the water switch is faulty, so the water switch cannot be closed in time.

Water pressure is unstable, which may be due to the decline in the performance of the high-pressure pump, or the pressure fluctuation of the water source, resulting in insufficient or excessive water pressure. ·The mixing tube does not match the nozzle, which may be because the size, shape or material of the mixing tube and the orifice are inconsistent, or because the mixing tube and the orifice are not installed correctly, resulting in poor water flow.

If you want to solve the waterjet cutting nozzle backwater problem, you can refer to the following suggestions: ·

Regularly check and replace mixing tubes, choose good quality, suitable specifications, and no impurities pomegranate abrasive, and avoid using expired or damp pomegranate abrasives.

Regularly check and maintain the water switch, replace damaged seals or solenoid valves, and ensure that the water switch can work normally. ·Regularly check and adjust the water pressure, choose the appropriate high-pressure pump and water source, and avoid the water pressure being too low or too high. ·

Regularly check and adjust the matching degree of the water jet nozzle and the orifice, choose the nozzle and orifice of the same model, and install and fix them according to the correct method.

What is the reason for the frequent breakage of the waterjet mixing tube/nozzle/focusing tube? Is there any solution?

The reasons for the frequent breakage of the waterjet cutting nozzle may be as follows: ·

The quality of the focusing tube is not good. It may be because the material, process or specification of the focusing tube is not up to standard, resulting in insufficient strength, hardness or wear resistance of the focusing tube, and it is easy to be broken by high-pressure water flow and abrasive erosion.

Improper use of the focusing tube may be due to incorrect installation, adjustment or maintenance of the focusing tube, resulting in improper position, angle or tightness of the focusing tube, resulting in deformation, loosening or wear of the focusing tube.

The focusing tube has been used for a long time, it may be because the service life of the focusing tube has reached or exceeded the design standard, resulting in a decline in the performance of the focusing tube, which cannot withstand the impact of high-pressure water flow and abrasives.

If you want to avoid the problem of broken waterjet cutting nozzle, you can refer to the following suggestions: ·

Choose focusing tubes with good quality, suitable specifications and no defects, preferably original or imported focusing tubes, and avoid using inferior or counterfeit focusing tubes.

Install, adjust and maintain the focusing tube according to the correct method and steps to ensure the matching and stability of the focusing tube and the nozzle, and regularly check and replace the focusing tube. ·Choose the appropriate water pressure and abrasive according to the cutting material and thickness, avoid too high or too low water pressure, and avoid using too large or too hard abrasive.

Record and control the use time and frequency of focusing tubes, replace new focusing tubes in time according to the life standards of focusing tubes, and avoid using expired or damaged focusing tubes.

What is the reason why the water jet nozzle/mixing tube/focusing tube is always blocked?

The reasons why the waterjet cutting сопло is always blocked may be as follows: ·The sand particles are too large, exceeding the inner diameter of the nozzle, so that the sand cannot pass through the water jet nozzle smoothly, but accumulates in the nozzle and becomes blocked.

The dust content in the sand is too much. After being exposed to water and damp, the sand is easy to consolidate into agglomerates and block the water jet nozzle

The quality of the sand is not good, containing impurities or moisture, which affects the fluidity and cutting effect of the sand. ·The installation of the nozzle is not correct, resulting in the bending of the nozzle is too large or too small, which affects the conveying speed and direction of the sand

If you want to solve the problem of waterjet cutting nozzle clogging, you can refer to the following suggestions:

Choose good-quality, fine-grained, dry and pure pomegranate sand, and avoid using sand that contains impurities or moisture

Regularly clean and replace the sand box and sand tube to remove dust and impurities, keep the sand box and mixing tube dry and clean.

Install and adjust the mixing tube according to the correct method and steps to ensure the matching and stability of the mixing tube and the nozzle, and avoid excessive or small bending of the sand tube.

If the mixing tube is found to be clogged, special water pipe tools or equipment can be used to break and remove the dirt in the pipe and restore the normal operation of the water jet

How long is the life of the waterjet cutting nozzle?

The life of the waterjet cutting nozzle is affected by many factors. Generally speaking, there are the following aspects: ·The material and quality of cutting nozzles are generally made of composite tungsten carbide materials with high hardness and high wear resistance, which can effectively resist the erosion of high-speed water flow and abrasives ·The size and quality of the sand, generally fine, dry and pure pomegranate sand, can effectively reduce the wear and blockage of the sand pipe.

The ratio of the inner diameter of the orifice nozzle to the inner diameter of the mixing tube is generally 1:3. For example, the inner diameter of the mixing tube is 1.0mm, and the inner diameter of the orifice nozzle should be 0.3mm, which can ensure the straightness of the water column and the cutting effect.

The concentricity of the orifice nozzle and the mixing tube generally ensures that the water column passes through the inner hole of the mixing tube smoothly, so as to avoid the sideways deviation of the water column and impact on one side of the inner wall of the mixing tube, resulting in uneven wear.

The cleanliness and hardness of the water quality generally ensure that the water quality is fully filtered to avoid impurities or hard objects that may cause damage to the orifice nozzle or mixing tube. According to different factors, the life of the water jet sand tube will also vary, generally between 100-300 hours. In order to prolong the life of the water jet mixing tube, the sand box and sand tube can be cleaned and replaced regularly to remove the dust and Impurities; after every 10-20 hours of use, rotate the sand tube 120 degrees; use professional tools and methods to install and adjust the orifice nozzle and mixing tube to ensure concentricity and stability.

How many waterjet cutting nozzle do I need to consume in a year if I buy a waterjet cutting machine, and how much do I need to stock up?

The number of mixing tubes that the abrasive waterjet cutting machine needs to consume in a year mainly depends on the service life and frequency of use of the mixing tubes. The service life of the mixing tube is affected by many factors, such as the material, quality, specification, size, installation, adjustment, maintenance, and replacement of the mixing tube. Generally speaking, the life of the waterjet mixing tube is between 100-300 hours, but it may be shortened or extended for various reasons.

Therefore, in order to accurately estimate the number of waterjet cutting nozzle that need to be consumed in a year, the following issues need to be considered:

How many hours does the waterjet cutting machine work per day? How many meters does the waterjet cutting machine cut per hour? ·What type and brand of waterjet cutting nozzle is used for the waterjet cutting machine? What type and quality of water and sand are used in the waterjet cutting machine? Does the waterjet cutting machine regularly check and adjust the concentricity of the orifice nozzle and waterjet cutting nozzle? Whether the waterjet cutting machine is regularly cleaned and replaced with sand box and sand tube? Does the waterjet cutting machine rotate the waterjet cutting nozzle regularly to evenly distribute wear? If the above questions have clear answers, then the number of waterjet cutting nozzle that need to be consumed in a year can be estimated according to the following formula: N = T / L Among them, N is the number of mixing tubes that need to be consumed in a year, T is the total working time (hours) in a year, and L is the average service life of waterjet cutting nozzles (hours). For example, if the waterjet cutting machine works 8 hours a day, cutting 10 meters per hour, using the waterjet cutting nozzle, the water and sand are of high quality, the concentricity of the orifice nozzle and the waterjet cutting nozzle is good, and the sand box and sand box are cleaned and replaced regularly. Waterjet cutting nozzle, rotate the sand tube regularly, then it can be assumed that the average service life of the mixing tube is 200 hours, then the number of mixing tubes that need to be consumed in a year is: N = 365 x 8 / 200 N = 14.6 That is, about 15 mixing tubes are needed.
