FIELD: oil industry. SUBSTANCE: vibration of pumping set caused by assemblage of elements included into it is measured simultaneously in process of its operation. Trends are plotted with the aid of computer monitoring by vibration in individual frequency bands. By them values of vibration parameters and rate of their change are determined simultaneously. Fast, slow and alternating trends are isolated. Parameters and trends are used as diagnostic indicators. System is taught to computer monitoring in advance by entering into it threshold values and combinations of indicators. Complex evaluation of condition of pumping set and of its elements is conducted by table dependence. EFFECT: enhanced authenticity of method. 14 dwg
