Gas transfer pump and adjustment of the pump body

Measurement and adjustment of the pump include alignment, looking for elevation and leveling three areas.
(1) vertical alignment is to find the gear meshing being, the horizontal centerline. Longitudinal diesel fuel dispenser centerline of the gear meshing is based on the shaft centerline prevail; transverse centerline to gas transfer pump centerline of the outlet pipe shall prevail. Looking positive, according to the mounted device centerline (or base and wall studs centerline) to be measured and adjusted so that the longitudinal internal gear meshing, and cross the center line to gas transfer pump meet the requirements of mobile fuel dispenser drawings and is well connected with other devices. Internal gear meshing , the horizontal centerline dimensions by drawing tolerances within ± 5mm range. Is the shaft centerline elevation (2) to find the elevation of the pump prevail. Generally used to measure the water level when mechanical fuel dispenser looking for elevation. When gas transfer pump measuring, the benchmark reference point on the plant settings, measured water level of the mounted height, and then moved to the journal benchmark, measure the distance from the shaft surface mounted to, and then the pump can be calculated according to the formula shaft centerline elevation.
