弹簧管压力表在生产和维修过程中,往往需要进行反复调整。但压力表的机芯、弹簧管及连接杆等,都被度盘遮住,调整时必须卸去指针和表盘。这样每调整一次,就要拆装一次指针和表盘,十分麻烦和费时。特别是指针拆装次数多了,往往会使中心齿轮轴弯曲,引起示值偏差。我们在调整压力表时,使用雕空度盘,避免了上述缺点,提高了工效和调整质量。 Bourdon tube pressure gauge in the production and maintenance process, often need to be repeated adjustments. But the pressure gauge movement, spring tube and connecting rod, etc., are covered by the dial, adjust the pointer and dial must be removed. This adjustment every time, we must disassemble a pointer and dial, very troublesome and time-consuming. In particular, more frequent disassembly of the pointer, tend to make the central gear shaft bending, causing the indication deviation. When we adjust the pressure gauge, the use of carved disk, to avoid the above shortcomings, improve work efficiency and adjust the quality.
