Preparatory work and installation sequence for gear pumps, screw pumps, and centrifugal pumps

Thread Content

Preparatory work before installing gear pumps, screw pumps, and centrifugal pumps: 1) Inspect the pump and motor to ensure that they have not been damaged during transportation and handling. 2) Prepare the necessary tools and lifting equipment, and check the foundation of the machine according to the specifications. Installation sequence for gear pumps, screw pumps, and centrifugal pumps: 1) When the complete pump set arrives at the site, the motor is already installed; it is not necessary to remove the pump and motor when leveling the base. 2) Place the base on the foundation, preparing it for leveling before filling it with concrete. 　　3) Use a level to check the levelness of the base by referring to the plane of the pump’s discharge outlet; once it is leveled, install the foot bolts and fill them with concrete. 　　4) Place the steel ruler on the coupling (measure from top, bottom, front, and back) to check whether the axis lines of the pump and the motor coincide. 　　5) Once the concrete surrounding the anchor bolts has fully cured, tighten the nuts of the anchor bolts. Finally, check the levelness of the entire unit; if there is any unevenness, it can be leveled using wedges. 　　6) Install the inlet and outlet pipelines; when connecting the pipelines to the pump, care should be taken to ensure that the weight and pressure of the pipelines do not exert stress on the pump, thereby preventing it from deforming. 　　7) Clean the environment and maintain hygiene.
