What a great feeling it is to be in the zone when throwing tungsten darts. You just know that every throw is going to be spectacular. Unfortunately, being in the dartboard zone doesn’t happen all that often for most amateur tungsten dart players. Here are a few tips to help you get in the zone more often:
Positive visualization. Close your eyes and visualize the tungsten dart going exactly where you’re aiming. Remember the last time you threw a great round of tungsten darts. Close your eyes and picture your tungsten dart landing in the perfect spot. Channel the positive energy through your arm to your fingers and to the eventual release of the tungsten dart. Open your eyes, take a moment to concentrate on your physical target and throw your darts with confidence.
Stretch and warm up properly. We all forget to stretch, but it goes a long way to ensure a great round of tungsten darts. Get your physical body ready to throw by stretching your finger joints, forearms, biceps, triceps and back. If you are stiff at the start of a match there's a good chance you will start slow and it could affect your confidence at the dart line.
Have a calm state of mind. Concentrate on slowing down your heart rate. Before a match, minimize any activity that makes you anxious. Get to the match early and try to relax. Take a walk around the block. Concentrate on slowing down your breathing throughout the night. There have been many studies that link a breakdown in motor reflexes with nervous, quick breathing.
Don't over-think it. Have confidence in your game and throw your tungsten darts. The zone will come, but you can’t force it. So get over the thought that you have to be perfect every time you throw. Play as if each dart is a new dart and keep a positive attitude. Just believe in your game and let them rip.

Tungsten carbide pulsed jet-flow is uncertain, which enhances the prompt impact of nozzle axis. Most of rocks are fragile and compressed energy will be stored in rock formations. When the cycle is unloading, the compressed energy inside the rocks is releasing on surface to swell, which pushing the rock crumbs out. However, when the tensile stress inside is exceeding the limit of rock, it will be broken. In addition, there are two characteristics of tungsten carbide pulsed nozzle using in drilling. One is the cycle of impact is discontinuous and uneven, another is lateral overflow with three patterns of purification (speed, kinetic energy, shear stress) moves the debris. Therefore, tungsten carbide pulsed nozzle has to be applied in many oil and gas fields, under the same conditions and relatively conventional continuous jet nozzle can be increased by 20% -40% penetration rate, drill footage increased by 15% -25%.

Tungsten carbide hollow atomizing nozzle is the most extreme requirement in atomizing quality (especially applied in aviation and combustion engine). Due to its average smaller size, it can deal with a part, which surface is larger and has a huge influence on substance movements. Consequently, tungsten carbide hollow atomizing nozzle is widely used in industry stove kiln, cooling, metal part surface treatment, air humidification, dustproof and coating. Its support spraying angle common sizes are 30°, 45°, 60°, 90°, 120°, 160°, and types are thread connection, ferrule connection, quick-release connection and welding connection, etc.

When drilling, owing to the drilling machine and rock crushing separating the cuttings often pressed at the bottom by huge pressure differential, which also known as "cuttings hold effect." And this effect is easy to form large clumps of plastic so as to form a layer of "cushion" between the drill bits and inside rocks. Therefore, the drilling speed is decreasing and the abrasion of drilling bit is accelerating. The most significant part of drilling is hydraulic power and the spray drilling takes full advantage of this for cleaning and rock breaking. The related statistics show that tungsten carbide pulsed nozzle prompt energy is 1.5 times bigger than normal nozzle, and effective distance is improved so that the pressure is distributing more reasonable, and the efficiency is enhanced.
