MAIN PROBLEM IN A HYDRAULIC SYSTEM IS....CONTAMINATION
HYDROBLAST
Gaima recommends that a Hydroblast is conducted before the Oil Flush. Hydroblast can tremendously reduce the amount of contamination in the piping system and will also allow a shoter Oil Flush time.

The reason why we recomended a System Hydroblast on both new and vintage plants in to blast out debris from peping after new construction or removal of rust, sludge & scale that may have accumulated in piping and systemsin vintage plants.

Benefits from the Oil System Hydroblasting Procedures:

  • Removal adhered rust, scale & sludge
  • Effectively removes contamination from guarded drain lines
  • Decreases oil flushing time to archive a clean system
  • Very addective on older systems
    • FLUSHING HIGH VELOCITY

    EHC & MHC SYSTEM FLUSHING
    One of the highest categories of forced outages on electro hydraulic controlled (EHC) steam turbines over the past 10 years has been the Tuerbine Trip and Monitoring System.

    The EHC Hight Pressure fluid system is a complex network of servo valves, filter relief valves, actuators, pumps, and directional control valves that operate in phosphate ester fluid. In a majority of the cases, the fluid systemwas either directly or indirectly responsible for the forced outage. Fluid contamination was found to be the singles biggest recurring problem with the hight pressure fluid system.

    Since the fluid is the heart of the system, contamination has become a major concern in maintaining unit reliability.
    A simple check of the servo valve strainers can quickly reveal contamination in the hight perssure fluid syste. In most cases ,the contamination consists of gels and/or varnishes.

    The fluid used in the EHC system (photosphate ester) is very sensitive to acid formation. The Hydraulic PowerUnit (HPU) incorporates a series of filters (Fullers Herat or Selexsorb) tha aid in controlling the acid build up in the fluid. If the filters are not properly maintained, the acid levels can increase to a point whe gels begin to from in the fluid. The gels will eventually from and migratethrough the filter media and form hard deposits throughout the entire system. These deposits can cause serious problems with the various components of the EHC , including servo valve failures, pump and actuator wear.

    The most reliable way to remove the deposits form the system is to flush the system using a cleaning agent fluid that dissolves the deposits and flushes it black to the reservoir where it can be removed. The acids are then removed from the hydraulic system following the flush. The flush can generally fluid be completed in five (5) days or less from start to finish.

    Throughout theprocess to guarantee the correct execution an on-site independent fluid analysis representative will be talking fluid samples and analyzing the fluid throughout the flush.
