IE C010TECHNICAL REPORT OF 20 DECEMBER 2000
CHIRANA turbine handpiece and compressor: play gone, faster air charging
The compressor began reaching operating pressure faster, handpiece bearing play disappeared. 16.7 % — compressor output: receiver charging to 4 kgf/cm², 35 → 30 s (2000).

Key result
| 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.
