1. Double deck foundation installation: the pump is installed on the basis of the motor mounted on the basis of (that is, on the basis of motor). Pump axial force from the motor bearing bearing, pump operation, the total foundation under the load for the next basic force + motor based on the sum of the force.
Under the pressure of the foundation = pump shell weight + pump shell water weight - pump axial water thrust on the basis of force = motor weight + pump rotor weight + pump axial water thrust.
2. Single base installation: using this form of installation, water pump and motor to form a whole direct connected structure, the entire unit is installed in the motor on the basis of the pump shaft and the motor shaft with rigid coupling, pump running total load for motor based force.
Motor Foundation (single layer foundation) stress = pump shell body weight + pump rotor weight + motor + pump casing water weight tips: the installation base is different, the position of the drainage elbow is also different. If the use of double base installation, drainage pipe should be between the two base; if the use of a single base installation, it should be set on the basis of the need for. The water pipe should be a separate frame, not by the pump body support; pump between the water pipe and the water outlet valve should be set up diffusion tube, its length is not less than 5 times the size of the diffusion tube diameter difference, outlet valve at best can hang a balance hammer, to balance the weight of the valve.
