Pressure gauge debugging technique

General pressure gauge assembly set-up the general pressure gauges and other common sense; Full amount & throughout; 、“ Small amount of whole & throughout; 、“ All large amount & throughout; In general, an Angle of 270 degrees on the dial scale. Within the scope of the pressure gauge measurement, it's on the corner of the pointer on the dial is 270 degrees, 270 degrees it is called the gauge & other Full amount & throughout; 。 Within the scope of the pressure gauge measurement pointer on the dial of the Angle is less than 270 degrees, it is called a & other; Small amount of whole & throughout; 。 Within the scope of the pressure gauge measurement pointer on the dial of the Angle is greater than 270 degrees, it is called a & other; All large amount & throughout; 。 How to adjust the pressure gauge pressure gauge of the full amount after the movement of axial position alignment, shall, first of all, to adjust the full amount of seismic pressure gauge, pressure gauge, as well as the adjustment technology for the full amount is: in the case of without pressure, will be a pointer to the left, a horizontal pin set ( OA) , the pressure within the table, make the pressure to achieve the instrument measurement limit ( From the standard pressure gauge reads) , whose hands clockwise rotation, if to vertical position ( 办公自动化的 ） , namely the pointer running 270 degrees all of this instrument is appropriate. If the pointer is not A’ All points, a little; If more than OA’ Point, explain the whole quantity. If the pressure gauge complete quantity is small, loosen the tooth bottom screw, connecting rod to the left ( On) Dial, then the full amount. If the pressure gauge complete quantity is big, loosen the tooth bottom screw, connecting rod to ( Below) Strike, the full amount.
