Maintenance, repair and service of pumps. Laser alignment and analysis of pump vibration
Maintenance and service of pumps should always raise the efficiency factor, reduce power consumption and increase the pressure and the volume of the pumped liquid per minute or per hour.
In accordance with the concept “Reliability technologies” the repair frequency of pumps is stated according to the plan of the Scheduled Maintenance or Maintenance Based on the Actual Condition and the repair size of pumps should be specified in the pump data sheet due to their operating time. Pump repair might be mid-life, routine or capital. Warranty repairs must be carried out by representatives of pump manufacturer using laser alignment systems or low-cost systems BALTECH SA-4100 series and calibration shims BALTECH-23458N series. After the warranty repair of pumps is done, manufacturer representatives must issue an additional warranty card prolonging the pump life for at least 6 months.
Before pump repair it is always necessary to perform final check (vibration analysis) by the experts of the technical service of the company BALTECH or on its own with the analyzer BALTECH VP-3470 for pump diagnostics and the software BALTECH-Expert. After vibration analysis and check of the technical condition of a pump according to a report or a diagnostic card the necessary amount of maintenance and repair of pumps as well as the depth and the development stage of defects will be clear. Based on the development stage of defects and the critical condition of pumps you should perform step-by-step quality repair including: disassembly and replacement of units, seals, bearings, dynamic balancing of impellers and alignment with the shims BALTECH-23458N. Final check of pumps can be performed with the vibration meters BALTECH VP-3410 or the thermal imaging cameras BALTECH TR-01800 Zorro. During pump repair installation and replacement of rolling element bearings should be always conducted with the induction heaters BALTECH HI-1612 series.
The pump repairs must be performed in compliance with safety requirements, and the experts performing these works should be certified in the training center BALTECH.
