With the rapid development of the shipbuilding and ship repairing industries, in order to improve the efficiency of blasting machine blasting equipment
and reduce the time wasted due to downtime and adding sand, two-cylinder single-gun and multi-gun blasting machines were born. Can continuously add sand, no need to stop adding sand, continuous operation can greatly improve efficiency, since 2001 has been widely used.
From the development history, the first sand blasting machines are basically jet type (negative pressure type), that is, the negative pressure of air jet can be used to draw the abrasive into the mixing cavity and spray it to the workpiece. Low, sand blasting efficiency is extremely low, not suitable for large-area, high-efficiency cleaning occasions, so it has gradually been replaced by direct-pressure sandblasting machines. Now the models used by various manufacturers are basically direct-pressure sandblasting machines.
The biggest features of the accessory
models are smooth blasting, strong blasting force, high energy utilization and high blasting efficiency. In addition, the impact of sandblasting equipment on the efficiency of cleaning also includes the rationality of structural design, the continuity of work, the convenience of use, and the sensitivity and speed of reflection.
Factors that affect the efficiency of blast cleaning include abrasive conditions, operator proficiency, and nozzle material. I will not discuss them one by one here. From the above analysis, it can be seen that the impact of blast cleaning efficiency is very intuitive in terms of a single independent factor, but due to the constraints of environmental conditions, various factors are difficult to achieve the optimal The effect, such as the diameter of the nozzle, should be as large as possible, but from the perspective of safety, the human body is prone to fatigue for a long time. In principle, the nozzle diameter of the manual operation must not be greater than 12㎜;
In addition, when the air supply of the air compressor is 6m3 / min, if the nozzle with a bore of 12㎜ is selected (at this time, the nozzle with a 10㎜ should be selected), the efficiency of cleaning the blasting machine accessories
will not increase, but will increase. Decreases accordingly. Therefore, in order to maximize the efficiency of blast cleaning, it is necessary to comprehensively analyze and deploy according to the environmental conditions in which it is located, so as to achieve the best results.
