在用气相沉积法(MCVD)生产光纤予制棒的工艺过程中,氢氧焰喷灯(以下简称灯头)和玻璃车床车头(以下简称车头)转速的快慢与稳定,直接关系着光纤予制棒的质量。为了对灯头和车头速度有一个直观反映,便于及时发现故障,修正速度和便于做工艺试验,我们试制了一台测速仪。它能反映 0～999.99毫米/分的灯头速度和 0～999.9转/分的车头转速,
In the process of producing the optical fiber preform rod by the vapor deposition method (MCVD), the speed and stability of the rotational speeds of the oxyhydrogen flame burner (hereinafter referred to as the base) and the glass lathe head (hereinafter referred to as the front) are directly related to the optical fiber preform rod quality. In order to have an intuitive reflection of the lamp and the front speed, easy to find the fault in a timely manner, to amend the speed and ease of doing technology test, we trial a speedometer. It can reflect the lamp speed of 0 ~ 999.99mm / min and the front speed of 0 ~ 999.9rpm,
