Abstract
The present application relates to a plunger pump, and the technical field of high-pressure media transport equipment. The plunger pump comprises a fixed component, a motion component and a fault diagnosis module, the motion component is provided on the fixed component, and the motion component is movable relative to the fixed component. The fault diagnosis module comprises a temperature sensing component and a processing unit, the fixed component is provided with one or more temperature detection holes, the temperature sensing component is at least partially located in the one or more temperature detection holes, and the temperature sensing component is contactable to lubricating oil flowing through the motion component; the processing unit is connected to the temperature sensing component, and the processing unit performs monitoring and fault diagnosis on the plunger pump based on a temperature value sensed by the temperature sensing component.
