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.
Claims30
A sensing device for a centrifugal slurry pump having an impeller which rotates about an axis, the centrifugal slurry pump including a front side liner and a main liner housed within an outer casing of the pump, the front side liner comprising a front face and a rear face, the front face arranged to face the impeller housed within the main liner, and the rear face arranged to face the outer casing the sensing device comprising:
- a body portion arranged to pass through the outer casing, wherein the body portion includes a sensor in contact with the front side liner, wherein the sensor is biased towards contact with the front side liner, the front side liner arranged to be axially adjustable with respect to the main liner, and the sensor arranged to remain biased towards and in contact with the front side liner when the front side liner is axially adjusted with respect to the main liner of the pump.
A system for detecting wear in a centrifugal slurry pump with a front side liner and a main liner housed within an outer casing, wherein the front side liner is arranged to be axially adjustable with respect to the main liner, 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 the front side liner and which is arranged to remain biased towards and in contact with the front side liner when the front side liner is axially adjusted with respect to the main liner.
A method of detecting wear in a centrifugal slurry pump with a front side liner and a main liner housed within an outer casing, wherein the front side liner is arranged to be axially adjustable with respect to the main liner, 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 sensing device relative to the pump such that the sensor is biased towards and in contact with the front side liner;
- communicating a first thickness reading and a second thickness reading of the front side liner from the at least one sensing device to a computing device;
- determining a change in thickness of the front side liner due to wear using the computing device;
- and
- axially adjusting the front side liner relative to the main liner in accordance with the change in thickness of the front side liner.
