compressor output: receiver charging to 4 kgf/cm², 35 → 30 s
| EQUIPMENT | CONDITION BEFORE TREATMENT | WHAT WAS MEASURED |
|---|---|---|
| CHIRANA turbine handpiece No. 9257 | Play in the bearings, bur runout during operation | Bearing play, bur runout during operation |
| CHIRANA compressor, made in Czechia | Oil passed through the piston group into the receiver; charging to 4 kgf/cm² — 35 s | Receiver charging time, oil ingress into the receiver |
CHIRANA compressor — before and after treatment
| PARAMETER | BEFORE TREATMENT | AFTER TREATMENT |
|---|---|---|
| Receiver charging time to working pressure 4 kgf/cm² | 35 s | 30 s |
| Oil ingress into the receiver through the piston group | Oil entered the receiver | Significantly reduced |
Both time measurements were taken at the same receiver working pressure — 4 kgf/cm².
CHIRANA turbine handpiece No. 9257
| PARAMETER | BEFORE TREATMENT | AFTER TREATMENT |
|---|---|---|
| Play in the handpiece bearings | Present | Gone |
| Bur runout during operation | Present | Stopped |
The handpiece was restored without disassembling the unit and without replacing the repair group.
Cost of restoring the units
| UNIT | STANDARD ROUTE | WITH XADO TECHNOLOGY |
|---|---|---|
| CHIRANA turbine handpiece No. 9257 | Replacement of the repair group made in Russia, Kazan — 96.00 UAH | 40.00 UAH |
| CHIRANA compressor | Repair of the piston group with the equipment taken out of service | 80.00 UAH |
December 2000 prices as calculated by the organisation that performed the treatment; labour costs and equipment downtime are not included.
Conclusion of the report
Before treatment, the bearings of CHIRANA turbine handpiece No. 9257 had play and the bur ran out during operation; the compressor let oil through the piston group into the receiver and reached the working pressure of 4 kgf/cm² in 35 s. After treatment with XADO technology the play disappeared, the runout stopped, oil ingress into the receiver decreased significantly, and the receiver reaches the same pressure in 30 s. The worn units returned to service on site: replacement of the handpiece repair group was not required. Verbatim conclusion of the report: "Repair using the 'XADO' technology is carried out in normal operating mode and requires no special equipment, premises or spare parts".
The results refer to CHIRANA turbine handpiece No. 9257 and the CHIRANA compressor of the Vitadent dental office, Kremenchuk; on other equipment and under other operating conditions the figures may differ.
