The water jet nozzle is one of the most commonly used fittings. The good sand mixer can work for a long time and save the cost for the customers, and the inferior sand mixing pipe will appear all kinds of problems after a period of time, and the sand tube is replaced lightly, the situation is serious and it can not be broken or cut. In what way is the sand tube good and bad?
1, the best steel material
It is better to use the tungsten steel with very high hardness as the material. Tungsten steel is a very high hardness metal material. It has very high compression, corrosion resistance, wear resistance and so on. It is the best sand pipe material at present. Some sand pipes are other materials, such as stainless steel, etc., the hardness and the tungsten steel have no small gap, the wear-resistant nature can not keep up, the use of short time is easy to problem.
2. Judging from quality
According to the different forging technology of tungsten steel, inside density and pure degree is not the same, generally the higher the better composition of tungsten steel. Tungsten steel has a characteristic, it is relatively heavier than other metal materials, so it can judge the composition of sand pipe material by weight, and the quality of the same volume product is better, the better.
3. See the water mouth
See if the location of the nozzle is positive, offset or not round as far as the outlet is round as far as possible.
