BASEPLATE, В FREE STANDING B046
A freestanding baseplate should be designed to properly support a pump and driver/ This type of baseplate must be designed to provide its own rigidity, as there is no grout for additional support.
The desirable features of a freestanding baseplate are:
- No need for concrete foundation pads.
- An allowance for height adjustment can easily be included.
- Spring mounted bases provide vertical displacement under applied loads associated with thermal expansion of the piping.
- Slide bearing plates may also be provided below the stilts or springs to allow horizontal displacement associated with thermal expansion of the piping
The purpose of a baseplate is to provide a foundationunder a pump and its driver that maintains shaft alignment between the two. It must:
- Allow for initial mounting and alignment of equipment
- Survive handling during transportation to the installation site.
- Be capable of proper installation with minimum difficulty.
- Allow final alignment of the mounted equipment and allow removal and reinstallation of equipment.
- The baseplate must not be permanently deformed after the equipment is mounted at the manufacturing facility.
- A free standing baseplate must be rigid enough to maintain coupling alignment when subjected to loads from piping or motor torque.
- The rigidity shall prevent no more than 0.25-mm (0.010-in) parallel coupling misalignment
- And 0.005-mm/mm (0.005-in/in) angular misalignment when subjected to maximum motor and piping loads simultaneously.
