FIELD: machine engineering.
SUBSTANCE: method involves carrying out successive tests, fluid flow throttling at the outlet of the pump to a predetermined flow rate, measuring the fluid temperature changes at the pump outlet for a specified period of time and the pressure drop at the pump, the definition of values of diagnostic parameters and evaluation of the measured values of the parameters at different technical state of the pump tests. Next, further reduced the current performance of the pump. Carried throttling fluid flow at the outlet of the pump to a predetermined pressure differential value. Generate measuring flow of the pumped liquid and use the change in temperature at the pump outlet for a specified period of time, measured by throttling the liquid flow at the outlet of the pump to a predetermined pressure drop value, and the flow of the pumped liquid as additional diagnostic parameters.
EFFECT: increase of informativeness pump diagnostics and the ability to use in assessing the technical condition of the pumps in operation.
