Mobile Transformer Oil Purification Plants CMM 4

Oil Purification Plant CMM 4 (СММ6)

Oil Purification Plant CMM 4

Cmm equipment can Purification Plants

  • Removes Water from 100 ppm down to 10 ppm and from 50 ppm to 5 ppm in a single pass (ASTM method D-1533)
  • Reduces Gas content from fully saturated with air (10 to 12% by volume) to less than 0.1% (ASTM D-2945)
  • Removes Particulate Matter to 5 microns as standard or down to 0.3 micron (optional)
  • Improves dielectric strength up to 75 kV

The GlobeCore Oil Purification Plant CMM 4 m3/h  is designed for removal of solid particles and free and dissolved water from transformer oil, lubricating oil, turbine oil and compressor oil.

The GlobeCore CMM 4 Oil Purification Plant  is able to process oil on a “tank to tank” basis or directly on energized or de-energized transformers.  Trolley or trailer mounted, semi-automated, fully automated (PLC controlled) and explosion proof versions of this unit are available.  Optional equipment includes moisture probes, flow meter with totalizer, and 0.3 micron fine oil filter.

GLOBECORE OIL PURIFICATION PLANTS CMM 4; COMPONENT DESCRIPTION:

Vacuum Chamber

6_11

1-Oil Inlet ; 2-Vacuum Pump Connection; 3-Coalescer; 4-Oil Outlet; 5-Level Sensor; 6-Sight Glass

Vacuum Chamber Vessels and all internal parts are made of carbon steel and feature Coalescers, Sight Glass, Oil Level Controller, Foam Sensor and Vacuum Gauge.  The Vacuum Chamber’s rigid design makes it suitable for stationary and  cmm mobile installation.  Appropriate flexible connections are provided to the outlet and inlet pumps to minimize negative effect of vibration during plant operation and transportation.
Coalescers – The unit has four (4) built-in coalescers and are provided for the maximum  exposure of oil to the effect of vacuum.  Due to the reduced pressure, dissolved water and gases are vaporized through the secondary chamber and filtered into the atmosphere.
Secondary Chamber (Oil Trap) – serves as safety feature to ensure that no oil is pulled into the vacuum pump.
Vacuum Gauge – is provided to monitor Vacuum level in the Vacuum Chamber.
Oil Level Controller – consists of three capacitive probes provided to maintain required level of oil in the Vacuum Chamber.
Foam Sensor – rarely, under certain conditions oil foaming may develop.  When the Optical Sensor, installed in the Vacuum Chamber, detects a high level of foam it will actuate a Solenoid Operated Valve to reduce vacuum and foam level.
Vacuum ports – vacuum connection is provided to pull vacuum on transformer.

gorelkaOil Heater
36 kW Oil Heater has two  stage heating facility with 18 kW of power each. A low watt density heating elements (1.2 W/cm2) are used to prevent heat degradation of oil. The heater is controlled be electronic temperature controller.

 

motor_sInlet and Outlet Oil Pumps
“Calpeda” Centrifugal pumps with power consumption of 4 kW and capacity of 12m3/h are utilized to draw oil in and out of the vacuum system. All electric motors are protected by overloads.

pultInstrumentation and Controls
Manometers – are installed to monitor the state of Coarse and Fine Filters.
Temperature controller – takes an input from a temperature sensor and is connected to a control element of the heater.

filters1Filters
A Mesh Strainer is provided to remove large particles that could cause damage to the Inlet Pump.  A Coarse Filter for particles larger than 5 microns is installed at the entry port to the Vacuum Chamber.  Oil then receives its final treatment by passing through the Fine Filter designed to remove 99.9% of particles larger than 2 microns or with an optional 1 micron capability.

AutonicsMeasuring and control parameters are pre-set by the manufacturer.
Power and Heating Indicators and Switches, Inlet and Outlet Oil Pumps Switches– are located on the control panel.
Emergency Stop Button – is provided for safe shut down of the plant in case of emergency.

Alarms and Interlocks
GlobeCore CMM plants feature the following safety devises that ensure simple and reliable operation and will safely shut down the system in case of any alarm situation:

High Level Alarm – will alert plant’s operator by activating sound and light alarms and shut down the system safely should high level of oil persist.
Low Level Alarm – interlocked with the inlet pump low level alarm will safely shut down the plant in case of insufficient oil level.
Flow Sensor – only activates the Heater when oil flow is detected.
Foam Sensor – prevents excessive foaming
Overloads – all motors are protected by overload shutdown devices.
Alarms – sound and light alarm with silence button will alert plant’s operator of any emergency situations.

fullers-earth-cartridges-normalOPTIONAL EQUIPMENT
GlobeCore Fuller’s Earth Сartridges (ZP-260)
GlobeCore Fuller’s Earth systems are specially engineered to remove soluble contaminants such as acids, waxes, gums, resins, carbon residues and colloidal particles from transformer oil.  They are designed for oil polishing after purification. For large quantities of oil GlobeCore’s regeneration system is recommended.
Eplus e probeMoisture Probe
The transmitter provides on-line transformer oil measurement of both the moisture content and the temperature. The unit comes complete with a display showing the level of moisture in a “ppm” readout.
