'O' HEAD DESIGN

摘要

A discharge head features a motor mounting plate configured for mounting on a motor; a base plate configured for mounting on a pump assembly; an elbow transition mounted on the base plate configured for providing discharge from the pump assembly; a seal housing pipe coupled to the elbow transition configured for receiving a mechanical seal or packing arrangement; supporting pipes arranged between the motor mounting plate and the base plate; and ribs arranged between the supporting pipes and the seal housing pipe configured to prevent substantially lateral and torsional movement, including movement due to reacting hydraulic forces at a pump nozzle and inertia from a driver. The discharge head according to the present invention makes it quicker and easier to couple together the shaft of a pump and the shaft of a motor in such VTSH pumps when compared to the techniques known in the art.
