dust blasting and sandblasting the inner tube to create

 for high-speed fluid jet energy dissipation receptacle
Abstract of a fluid jet cutting system includes an axially lower end of a high density at the workpiece porous structure, and having a jet adjacent to the entrance of the workpiece receiver.molybdenum plating disposable suspensoid mounted in high-density porous structure, said colloidal suspension of at least a majority of the diameter ratio of the diameter of the hole. Porous structure located near the collection means to collect and remove from the porous structure of the material is discharged.
409 800 570 003 having a plurality of suction spray jet nozzle exit bicker
The present invention discloses a jet nozzle having a plurality of suction nozzles shoot. Two or more jet nozzles distributed in lead pipe sand sand around the ports. Due to improved lead pipe sand sand sand around the ports get energy conditions, making sand gas jet work ability strengthened. For the fire-suction blasting, dust blasting and sandblasting the inner tube to create the conditions to improve efficiency.
409800950004 transparent for sandblasting abrasive sand powder mixing tank
The invention is used for sandblasting abrasive, especially production of small diameter blind hole transparent Residual Stress Measurement sand powder mixing tank. Known similar devices, weighing about 18 kg, with separate sand powder injection mechanism, by injection of sand, Pressure and flow control, for different nozzles use the task of the present invention are: manufacture of a transparent sand powder mixing tank. abrasives.For undriven injection mechanism and adjust the meter parts, the use of reliable, transparent and intuitive, weighing about 1.5 kg, energy manufactured at low cost. Moreover, the tank inlet and the nozzle control valve to adapt to different needs replacement.
409 801 060 005 for polishing the surface of a gas turbine blade and apparatus
The invention relates to a method for polishing a gas turbine blade (20) a surface (24) of the method and apparatus. According to the invention, the corrosion of a metal layer (32) by means of a jet of dry ice (14) to the polishing, thereby avoiding the surface (24) is contaminated with impurities and obtain cost advantages.
409801520006 supersonic strong wear sandblasting
Abstract supersonic strong wear sandblasting machine is mainly used in processing industry sandblasted surface of the workpiece as a common tool. $ Used sandblasting wear (3-5), and a working efficiency is not high scrap, the utility model is the use of an annular Laval nozzle at a total pressure of air form a fixed number M of supersonic ejector airflow. Since the body of sandblasting, sand gas diversion, sandblasting subject only to become a non-contacting gas wear parts, and replaced by a sonic supersonic ejector ejector, air ejector enhanced ability to achieve increased leaf spray the life span and improving ejection efficiency.
