EHC & MHC Systems are a major contributor to forced outages throughout the Power Generation Industry.

MD&A’s Bearings, Seals & Hydraulics division has been troubleshooting and overhauling utility EHC and MHC components for more than 15 years.

Upon arrival, we inspect and disassemble the actuator revealing any problems or damaged components, along with draining all the fluids.

We photograph and document all components upon incoming inspection.

A unique stand for the actuators holds it in place while we depressurize the actuator with the disc springs inside.

A large inventory of Rexroth® hydraulic servos, solenoids, rebuild kits and disc springs is maintained to satisfy short-cycle turnaround requirements.

Documented functional testing of your actuator assures a seamless transition to system operations.

The first step in the testing process is to flush the actuator.

After flushing, the system is tested at the MD&A shop using the same type of hydraulic fluid that is used at the owners’ site.

The testing of all hydraulic control components repaired at MD&A greatly reduces the need for field adjustment during start-up.

MD&A provides shipping stands and containers for secure inbound and outbound transit.

MD&A offers short cycle turnaround for customers who encounter emergencies and need components repaired and returned as soon as possible.

During operation the owner observed erratic valve response and hydraulic fluid weeping from a telltale drain. The disassembly discovery revealed fractured disc springs and embrittled seals in the packing head and cylinder. The servo and poppet valves were damaged due to fluid contamination.

Shaft scoring and spring housing gaulling was also observed as a result of the above mentioned discovery.

Upon reassemble with new components, the Rexroth® actuator was functionally tested in a test stand at the MD&A shop using the exact same brand of EH fluid that is used at the owners’ site. MD&A provided shipping stands and containers for secure inbound / outbound transit.
