bearing vibration of the pumps and the boiler ID fan
| MACHINE | TYPE AND ITEM | WHAT WAS MEASURED |
|---|---|---|
| Network pumps | SE-1250-140, items SN-1 and SN-3 — 2 units | Bearing vibration, motor noise |
| Fuel-oil pumps | 5N-8x4, No. 1, 2 and 4 — 3 units | Bearing vibration, motor noise |
| TP-35 boiler ID fan | ORGRES07-132 — 1 unit | Bearing vibration, motor noise |
Results after 350-400 hours of running time
| COMPONENT | PARAMETER | RESULT |
|---|---|---|
| Bearing assemblies of the pumps and the ID fan | Bearing vibration | Reduction of 10-30 % |
| Drive motors of the machines | Motor noise | Reduction recorded in the certificate |
The results are given in the section "The following results were achieved" of the certificate; per-machine measurements are documented in Annex 2.
Scope of work and material consumption
| ITEM | VALUE |
|---|---|
| Work period | 12 February — 18 March 2002 |
| Machines treated | 6 — 2 network pumps, 3 fuel-oil pumps, 1 boiler ID fan |
| Running time before the repeat measurement | 350-400 h as per the XADO technology procedure |

The machines were treated by specialists of GT ODO VaTT following the XADO technology.
Conclusions and recommendations of the certificate
The RUP Grodnoenergo certificate states: the positive results obtained demonstrate the effectiveness of applying XADO technology to heating-network equipment. Restoration was carried out while the equipment stayed in service — repeat measurements of the same parameters were taken after 350-400 hours of running time of the treated machines. According to the conclusions of the certificate, XADO technology makes it possible to reduce machine noise and vibration and to cut equipment repair costs. The signatories recommend including restoration of machines by XADO technology in the scheduled equipment maintenance system; the technology is recommended for further roll-out at RUP Grodnoenergo and at other enterprises operating similar equipment. The work covered six machines of the Lida Heating Networks — network and fuel-oil pumps and the TP-35 boiler ID fan.
The results relate to the SE-1250-140 network pumps, the 5N-8x4 fuel-oil pumps and the TP-35 boiler ID fan of the Lida Heating Networks; on other equipment and under different operating conditions the figures may differ. The original RUP Grodnoenergo certificate dated 18.03.2002, signed and stamped, is published in full and available for download.
