技术介绍
微压计属于测压仪表的一种;微压计用于测量非腐蚀性气体的微小压力、真压及压力差,也可用来校准其它压力计,可供实验室和计量单位计生产单位使用;常用的微压计包括双液U形管压力计、斜管压力计(倾斜式微压计)、补偿式微压计。补偿式微压计主要用于非腐蚀性气体微小压力量值的传递校准和测试,它可测量微小气体的正压、负压和差压,可与S型皮托管或L型皮托管连接用于测量管道流速或差压,它可以作为标准器校准其他低精度的压力仪表。现有的补偿式微压计,该微压计包括机架,机架上设有可动容器和固定容器,固定容器固定在机架上,可动容器和固定容器通过软管连通,可动容器上连接有螺杆,螺杆上设有等分刻度盘,等分刻度盘上连接有螺母,通过旋转等分刻度盘可使可动容器升降,可动容器上固定连接有滑杆,机架上还设有标尺,滑杆滑动连接在标尺上,固定容器内设有水准头,固定容器顶端螺纹连接有接嘴,在可动容器和固定容器灌装有水。在测压力之前,将固定容器的液位调到与水准头顶端平齐,可动容器上滑杆位置处于零位,通过接嘴与外部被测气体连接,气体进入到固定容器内,固定容器内的液面下降,通过旋转等分刻度盘,使可动容器上升,直到固定容器内的液面重新达到与水准头顶端平齐的位置时,滑杆会在刻度盘上指示一定的示数,从而得到被测压力的数值。而在此补偿式微压计长期使用时,由于螺杆与螺母长期摩擦,并且两者的螺纹的厚度都较小,内螺纹和外螺纹相互旋转时,内螺纹和外螺纹将受到摩擦力和剪切力的作用,会使两者啮合的螺纹逐渐磨损,并可造成螺纹弯折,甚至螺纹损坏,从而可使微 ...
