The specific embodiment
Below in conjunction with drawings and Examples, the utility model will be further described:
As shown in Figure 1, main burner installation accuracy testing arrangement of the present utility model, comprises main burner air-flow measuring head 19, measuring head displacement indicating device, main burner support 15 and measuring head central fine setting device.
Measuring head central fine setting device is comprised of longitudinal micromatic setting and height fine-adjustment, this longitudinal micromatic setting comprises a longitudinal adjusting rod 10, one end at longitudinal adjusting rod 10 is connected with measuring head 19, the other end is provided with the first adjusting handle 1, longitudinally on adjusting rod 10, one section of external screw thread is being set, longitudinally fine-tuning nut 20 is threaded with longitudinal adjusting rod 10; Height fine-adjustment comprises a height regulating rod 3, the upper end of height regulating rod 3 is fixedly connected with longitudinal fine-tuning nut 20, the lower end of height regulating rod 3 arranges the second adjusting handle 2, one section of external screw thread is set equally on height regulating rod 3 to be threaded with height fine adjusting function nut 30, height fine adjusting function nut 30 is fixedly connected with bearing 21 by connecting rod 4, and whole measuring head central fine setting device is fixed and is supported.Main burner support 15 can be arranged on bearing 21, also can arrange separately, by the axis at the center that crosses and vertical setting of axis of longitudinal adjusting rod 10 of main burner yarn-guide tube 14.Longitudinally fine-tuning nut 20 forms screw thread transmissions with longitudinal adjusting rod 10, and height fine adjusting function nut and height regulating rod 3 form screw thread transmissions.
Measuring head displacement indicating device comprises the longitudinal scale 9 being arranged on longitudinal adjusting rod 10 and is arranged on the altitude scale on height regulating rod, be preferably in scale cover 22 be longitudinally set on longitudinal adjusting rod, this longitudinally scale cover 22 be fixedly connected with longitudinal fine-tuning nut 20; Be preferably on height regulating rod vertical scale cover is set, this scale cover 22 is fixedly connected with height fine adjusting function nut, the scale value of the front end face being overlapped by scale or rear end face indicator scale.
