喷砂设备可用作对金属的锈蚀层、热处理件表面的残盐和氧化层、轧制件表面的氧化层、锻造件表面的氧化层、焊接件表面的氧化层、铸件表面的型砂及氧化层、旧机件表面等进行处理。喷砂设备还可以改变工件表面粗糙度,可以产生亚光或漫反射的工件表面,以达到光饰加工的目的。所以喷砂设备被广泛应用于铸造机械行业中。
如何选择喷砂设备?要从以下几个方面考虑:
1.一般而言,喷砂设备的效果主要由零件材料及喷砂磨料决定。根据零件材料的不同,喷砂磨料范围可从效果强烈的金属磨料到效果柔和的树脂磨料,同时干喷砂与液体喷砂亦是重点考虑的因素。
2.生产效率确定喷砂设备种类。根据加工能力选择自动化喷砂生产线、半自动化喷砂设备、压入式喷砂机、吸入式喷砂机。
3.工件尺寸确定喷砂设备规格。根据工件尺寸选择机舱大小,以便有足够的空间完成处理工作。
4.压缩空气要求。根据喷砂设备规格确定空压机容量,并留20%余量,以保护空压机使用寿命。

Sandblasting equipment available corrosion layer, heat treatment of surface residual salt and oxide layer, the oxide layer on the surface of the rolling, forging, welding pieces of the oxide layer on the surface of the oxide layer on the surface of the casting surface, sand and the oxide layer, the old mechanical surface treatment. Sandblasting equipment can also change the surface roughness of the workpiece, can produce matte or diffuse to the surface of a workpiece, so as to achieve the purpose of finishing processing. So the sandblasting equipment is widely used in foundry machinery industry.
How to choose the sandblasting equipment? Should from the following several aspects to consider:
1 in general, sandblasting equipment effect parts from the main materials and blasting abrasive decision. According to parts of different materials, abrasive blasting can range from the effects of the strong metal abrasive to the effect of soft resin abrasive, and dry sandblasting and liquid sandblasting is also focused on the factors considered.
2 determine the efficiency of production of sandblasting equipment types. According to choose automated sandblasting processing capacity production line, semi-automatic sandblasting equipment, pressure-in sand blasting machine, suction type blasting machine.
3 workpiece size determine sandblasting equipment specifications. According to the workpiece size choose the cabin size, so that there is enough space to complete processing.
4 compressed air requirement. According to the blasting equipment specifications to determine the air compressor capacity, and left20% margin, in order to protect the service life of the air compressor.
