Abstract
An eductor for conveying materials includes a body defining a first end and a second end and having a first inlet proximate the first end and a body outlet proximate the second end, the body defining a second inlet positioned between the first inlet and the body outlet, and the body defining an interior area. The eductor includes one or more inserts disposed within the body. The insert or inserts are manufactured from an abrasion resistant material.
Claims22
An eductor for conveying materials comprising:
- a body comprising a pressure boundary, the body defining a first end and a second end and having a first inlet proximate the first end and a body outlet proximate the second end, the body defining a second inlet positioned between the first inlet and the body outlet, and the body defining a first interior area which extends between first inlet, the second inlet and the body outlet;
- and
- at least on insert disposed with in the body, said at least one insert being formed of an abrasion resistant material.
A method of refurbishing a worn eductor comprising:
- removing at least one of a mixing chamber insert, a motive fluid nozzle, a feeder conduit insert, a venturi outlet insert and a venturi inlet insert from the eductor;
- and
- installing at least one of a removable abrasion resistant mixing chamber insert, motive fluid nozzle, feeder conduit insert, venturi outlet insert and venturi inlet insert into the eductor.
An eductor for conveying materials comprising:
- a body comprising a pressure boundary, the body defining a first end and a second end and having a first inlet proximate the first end and a body outlet proximate the second end, the body defining a second inlet positioned between the first inlet and the body outlet, and the body defining a first interior area which extends between first inlet, the second inlet and the body outlet;
- a mixing chamber insert positioned in the interior area, proximate the first inlet and extending downstream thereof, the mixing chamber insert defining a second interior area that is in communication with the first inlet, the second inlet and the body outlet, the mixing chamber insert manufactured from an abrasion resistant material;
- a motive fluid nozzle positioned in the first inlet and extended at least partially into the mixing chamber insert, the motive fluid nozzle manufactured from an abrasion resistant material;
- a feeder conduit insert positioned in the second inlet, the feeder conduit insert defining a third interior area that is in communication with the second interior area, feeder conduit insert manufactured from an abrasion resistant material;
- a venturi outlet insert positioned in the body outlet, venturi outlet insert manufactured from an abrasion resistant material;
- and
- a venturi inlet insert positioned in the first interior area and having one end positioned proximate the mixing chamber insert, venturi inlet insert manufactured from an abrasion resistant material.
