Record of Performance

Introduction to some of our record of performance for maintenance and service

Maintenance and Service for Decanter Centrifuges

Record of Performance:Maintenance and service for decanter centrifuges

Maintenance and service for decanter centrifuges

We provide maintenance and service for decanter centrifuges used in steelworks. We repair fitting parts by plating and thermal spray, hard-facing of flights, dynamic balance corrections, and test runs. We also perform welding repairs for casings in some cases.

Record of Performance:Rewinding and hard-facing of flights

Rewinding and hard-facing of flights

We can also repair screws. Repairs are performed by rewinding or hard-facing worn flights. After repair, the outer diameter is machine-polished to predetermined dimensions.

Record of Performance:Dynamic balance corrections

Dynamic balance corrections

This process is indispensable to the maintenance and service for decanter centrifuges. Safe and stable operations are realized by vibration suppression during operations through dynamic balance corrections.

Record of Performance:Maintenance and service for differential gear units

Maintenance and service for differential gear units

The differential gear units mounted on decanter centrifuges include gear devices with planetary gears, cyclo speed reducers with cycloid discs and hydraulic motor speed reducers with a hydraulic mechanism. It is important to grasp the conditions of each tooth surface, fitting dimensions, journal clearances, etc.

Record of Performance:On-site installation of decanter centrifuges

On-site installation of decanter centrifuges

We can also provide on-site installations of decanter centrifuges and test runs at customer request.

Maintenance and Service for Speed Reducers

Record of Performance:Maintenance and service for overseas-made speed reducers

Maintenance and service for overseas-made speed reducers

We provide maintenance and service for speed reducers for parts which cannot be procured from overseas manufacturers. We perform fabrications of spiral bevel gears, investigations of parts, and modifications for the purpose of complying with standard products of oil seals, etc.

Record of Performance:Fabrication of gears

Fabrication of gears

Even in a case where a gear is damaged and requires fabrication, the same gear can be fabricated by reverse engineering from a sound part. We offer a record of performance in fabricating φ700 spiral bevels and pinion gears.

Record of Performance:Tooth contact checks

Tooth contact checks

For parts that use gears, including speed reducers, we check and adjust tooth contacts to confirm that the teeth are in proper contact with each other.

Record of Performance:Test runs of speed reducers

Test runs of speed reducers

We collect data for several hours by test runs after maintenance and service to confirm that speed reducers operate normally.
