External gear pump installation method

Elevation adjustment is accomplished with an electric washer engaging the external gear pump decrease  legs and between the base. Shaft center rib elevation deviation of ± 10mm. Internal gear meshing leveling electric pump centerline to find a good location and elevation, they start to adjust the level of external gear pump inside, first with fine age 0.05mm / m square meter level, in  external gear pump measurements performed on front and rear ends of the spigot. Adjust the level, you can add and subtract thin metal meshing between the external gear pump foot and the base unit within the electric adjustment. Level of engagement within external gear pump allowable deviation is generally 0.3-0.5mm / m. Internal gear meshing dispenser fuel pump centerline position, elevation and level of degree to find a good post, you can connect an electric bolt external gear pump and tighten the base, then use a level to check whether there are changes in its level, if no change, you can install the motor. The main job is to mount the motor to the center line of the motor shaft and the centrifugal pump is adjusted to the center line of the shaft in a straight line. Bedroom shaft multistage centrifugal manual fuel transfer pump and the motor are connected together using a variety of coupling, the installation operation of the motor is the main alignment coupling, a specific alignment method will be described in the assembly of the coupling . There must be an axial gap between the motor coupling halves, whose role is to prevent the shifting of the role of horizontal multistage centrifugal parts for pumps shaft spread to the motor shaft or motor shaft axis traverse action spread. Thus, this gap must be of a certain size, generally greater than the amount of play of the shaft and the centrifugal pump and the motor shaft. Typically this gap has specified on the drawings, as the paper is no such requirement, can be adjusted with reference to the following figures: Small centrifugal pumps for 2-4mm; medium-sized centrifugal pump for 4-5mm; large centrifugal pumps for 4-8mm.
