Maintenance and Service for Decanter Centrifuges

Decanter centrifuge

A decanter centrifuge is a machine that plays a central role in separation processes, such as dehydration and condensation, among various processes. Since the bowl and screw rotate with a slight clearance at high speed, they undergo many processes in maintenance and service, including proper disassembly, diagnosis, repair, and dynamic balance corrections.

Large Speed Reducers

Reducer

A speed reducer gradually reduces the high-speed rotation given to the input shaft via multiple gears that are different in the number of teeth and diameter, while it changes to a larger torque. This makes it necessary to have technology that can appropriately diagnose the conditions of the teeth through which force is transmitted and the conditions of the shafts and bearings that maintain rotation, whereby repairs, adjustments and assembly can be performed.

Roots Blowers

Roots blower

A roots blower is a machine that conveys air with multiple blades called impellers, which are installed on parallel shafts, and rotated in opposite directions. The original performance can be restored by the proper setting of the clearances between the blades and between the blades and the case based on the measurement of each part.
