Abstract
A sensing device for a centrifugal slurry pump having an impeller which rotates about an axis, the centrifugal slurry pump including a side liner and a main liner housed within an outer casing of the pump, the sensing device comprising; a body portion arranged to pass through the outer casing, wherein the body portion includes a sensor biased towards contact with either the side liner or the main liner of the pump.
Claims33
A sensing device for a centrifugal slurry pump having an impeller which rotates about an axis, the centrifugal slurry pump including a side liner and a main liner housed within an outer casing of the pump, the sensing device comprising;
- a body portion arranged to pass through the outer casing, wherein the body portion includes a sensor in contact with either the side liner or the main liner of the pump wherein the sensor is biased towards contact with either the side liner or the main liner of the pump.

A system for detecting wear in a centrifugal slurry pump with a side liner and a main liner housed within an outer casing, said system comprising at least one sensing device arranged to pass through the outer casing, wherein the at least one sensing device includes a sensor biased towards contact with either the side liner or the main liner of the pump.
(canceled)
A method of detecting wear in in a centrifugal slurry pump with a side liner and a main liner housed within an outer casing, the method comprising the steps of:
- arranging at least one sensing device to pass through a surface of the outer casing, the at least one sensing device including a sensor;
- arranging the at least one the sensing device relative to the pump such that the sensor is biased towards and in contact with the side liner or the main liner;
- communicating a first thickness reading and a second thickness reading of either the side liner or the main liner from the at least one sensing device to a computing device;
- and
- determining a change in thickness of the side liner due to wear using the computing device.
A sensing device for an unlined centrifugal slurry pump having an impeller which rotates about an axis, the centrifugal slurry pump including an outer casing of the pump, the outer casing including an inner surface and an outer surface, the sensing device comprising;
- a body portion arranged to engage with a bracket connected to the outer surface, wherein the body portion includes a sensor biased towards and in contact with the outer surface of the pump.
