Friction welding drive apparatus for repair of pipes and valves

摘要

In some implementations, an injection system that injects sealant into a pipe, pressure component or valve while containing the pipe, pressure component or valve repair that significantly reduces or eliminates release of hazardous material from inside the pipe, pressure component valve or injection system and thus significantly reduces emission of the hazardous material from inside the pipe, pressure component or valve into the environment and protecting the repair technicians.

主权项

1. A multi-motor friction welding drive system comprising:
a first pneumatic motor; a second pneumatic motor operably and serially coupled to the first pneumatic motor; a first hose being connected to the first pneumatic motor; a second hose being connected to the second pneumatic motor; a first controller and compressed air source being connected to the first hose; a second controller and compressed air source being connected to the second hose; an actuator being connected axially to the second pneumatic motor, wherein the actuator further comprises:
a compressed spring,a piston operably coupled to the compressed spring,a thrust bearing operably coupled to the piston,a drive shaft that passes through the compressed spring, the piston and the thrust bearing; a chuck being connected axially to the actuator; and a boss being mounted axially to the chuck, wherein the compressed spring is operable to apply a pressure to the thrust bearing which then applies a second pressure to the drive shaft, which in turn applies a third pressure to the chuck and the boss, the thrust bearing allows the drive shaft to rotate under the second pressure from compressed spring while allowing an axial force to be applied to the chuck and a fourth pressure on the boss is transferred to a valve during friction welding, as the boss is driven into the valve during the friction welding, the piston and the compressed spring absorb a spatial difference.
