Liquid sandblasting machine is a surface treatment equipment. Its working principle is based on jet technology. It uses a mixture of water and abrasives, and then completes the jet processing through secondary acceleration of compressed gas. This article will elaborate on the working principle of liquid sandblasting machine to help readers better understand the operating mechanism of this technology.
First of all, the liquid sandblasting machine consists of abrasive pump, water-sand mixing box, stirring device, injection system, control system housing, automatic auxiliary system, etc. The abrasive pump is responsible for providing a stable water-sand flow to ensure the continuous supply of the mixed liquid; the abrasive mixing box cooperates with the stirring system to provide the abrasive pump with a medium flow of fully mixed water and sand, and through secondary acceleration of compressed gas, a uniform, stable and high-speed jet is formed; the nozzle, as a key injection component, is responsible for injecting the jet at high speed onto the processed surface; the housing has the function of shielding and guiding, so that the water and abrasive in the jet can be quickly transferred to the mixing box, so that the injection work forms a closed loop.
In the working process of the liquid sandblasting machine, the abrasive and water need to be mixed through the matching device to form a uniform mixed liquid. Then, the mixed liquid is transported to the spray gun through the action of the water pump. At this time, the compressed gas acts as an accelerating force and enters the spray gun through the air pipe. Inside the spray gun, the compressed gas accelerates the mixed liquid to form a high-speed jet. Finally, through the action of the nozzle, the high-speed jet is sprayed onto the processed surface to achieve the purpose of cleaning and processing.
