活塞式压力计主要用于压力量值传递及高准确度的测试。压力计是安装在压力校验器上的,校验器可以产生压力,也可以起连通压力作用,首先调整水平位置,将被测压力引入校验器作用在活塞压力计的有效面积上,使活塞杆上升。活塞承重盘平面垂直活塞杆中心线,并按顺时针方向(30-60)转/分角速度旋转,减少活塞杆与活塞筒之间的摩擦力,然后读取被检压力表的指示值。压力计在使用中,长期使用不清洁的油污,使压力表弹簧管内壁附有油污腐蚀
Piston pressure gauge is mainly used for pressure transmission and high accuracy of the test. Pressure gauge is installed in the pressure checker, the checker can produce pressure, but also can play the role of connected pressure, the first adjustment of the horizontal position, the measured pressure is introduced into the checker acting on the effective area of the piston pressure gauge so that Piston rod rises. Piston bearing plate plane perpendicular to the centerline of the piston rod and clockwise (30-60) rev / angular rate of rotation, reduce the friction between the piston rod and the piston cylinder, and then read the pressure gauge was seized instructions. Pressure gauge in use, the long-term use of unclean oil, the pressure gauge spring tube with oil corrosion
