C 512 A立式车床的主轴变速箱及工作台导轨和主轴轴承的润滑,是由油泵将油压人过滤器再由过滤器送分配阀,由分配阀送至需要润滑的部位(图1)。这套过滤分配装置是由过滤器与分配问两个部件组成,中间由管路接头联接。所以管路接头多达20余件。加之其接管型式密封性能很差,在使用 C 512 A vertical lathe spindle gearbox and table rails and spindle bearings lubrication, is the oil pump hydraulic pressure filter and then sent to the distribution valve, the distribution valve to the need to lubricate the site (Figure 1) . This filter distribution device is composed of two parts of the filter and the distribution of asked, the middle by the pipe joints. So pipe joints up to more than 20 pieces. Coupled with its take-over type sealing performance is poor, in use
