我厂常见的滤油器结构形式如图所示。滤油器由铜网和钢件骨架联接在一起构成组合件。在液压系统中,它起过滤作用,受工作介质的冲击和浸蚀。由于工作温度一般较低(不超过100℃),所以大部分滤油器都采用钎焊结构,采用易熔钎料的烙铁钎焊。钎焊工艺如下: 一、钎焊前的准备 1.钢件骨架应进行表面镀锌或发蓝处理,以防锈蚀。 Our common structure of the oil filter as shown. Filter by the copper mesh and steel skeleton together to form the assembly. In the hydraulic system, it acts as a filter, by the impact of working medium and erosion. As the working temperature is generally low (not more than 100 ℃), so most of the oil filter are brazed structure, the use of fusible brazing soldering iron. Brazing process is as follows: First, the preparation before brazing 1. Steel skeleton should be galvanized or blue surface treatment to prevent corrosion.
