Telescoping column pipe assembly for fuel dispensing pumping systems |
摘要 |
An adjustable length column pipe for connecting a submersible electric pump in a fuel storage tank with a distribution head that distributes the fuel to dispenser units. Two telescoping column pipes can be telescopically adjusted to the desired length and then locked together by a locking mechanism. An adapter bushing is threaded onto the end of the larger diameter pipe and has a projecting sleeve. A fitting is threaded onto the sleeve and tightened to compress a seal ring which seals the lock assembly to the pipe. Projecting fingers on the fitting are wedged against the smaller telescoping pipe by a nut which is threaded onto the fitting and has a tapered surface to provide progressive wedging action. Electrical wiring for operating the pump is contained within a telescoping conduit assembly which extends inside of the column pipes and is isolated from the fuel passageway by a seal arrangement.
