Oil Filtration Plant

Oil Filtration Plant
OIL FILTRATION PLANTS CAN BE SUCCESSFULLY MODIFIED & AUTOMATED FOR VARIABLE FLOW RATE.
A brief description is given for your reference.
INLET & OUTLET PUMPS :
The pump will be driven by suitable sized AC drive to control the flow rate. By using these settings we can control the flow rate from i.e. If Plant is 6000 LPH then it will vary from 1000 LPH to 6000 LPH.
HEATER TANK :
It is also necessary to select proper heat output for variable flow rates. This will avoid localized heating of oil for small flow rates.
This section will incorporate PLC which will control the heaters.
PLC will be used for control of heater groups, once certain flow rate has been selected, heaters will be configured automatically to suit that flow rate.
This control panel will be designed for reliable & trouble free operation.
By using the above system the major benefit is to have a single machine instead of different models for different capacities.
In this case, flow rate can be kept variable from 1000 LPH to 6000 LPH. Power saving of 30% can be achievable by using this system as compared with traditional oil filter system designs.
OPERATIONAL & PROCESS AUTOMATION
Press'START'to start the oil filtration process.
All airing valves, oil inlet & outlet valve will close.
The rotary vacuum pump will start to achieve coarse vacuum.
After achieving coarse vacuum level, which the'Vacuum Switch'will sense.
After achieve the desired level of fine vacuum in the plant, oil inlet valve & intermediate valve will open and the oil inflow will start due to vacuum inside the plant. The flow switch provided in the suction line of the plant will sense the oil flow & that signal will start the oil inlet pump. In case, the incoming oil flow is not there, HMI on the control panel will display'LOSS OF OIL', with annunciation. One pressure release valve, provided across the inlet pump will control the excessive pressure rise in the plant.
As oil is filled in the degassing chamber, the high level float switch will operate & that will put'OFF'the inlet pump & start the outlet pump. The starting signal to the outlet pump will open the outlet valve. As the oil level in the degassing chamber comes down, the high level float switch will start the inlet pump, again. Thus the oil circulation through the filtration plant will start.
After the continuous oil flow through the plant, the heaters will be'ON'.
Temperature of oil will be controlled by TIC (Temperature Indicating Controller) & one safety thermostat will control the accidental temperature rise.
Thus the hot oil circulation through filters & degassing chamber will start resulting in the effective separation of solid impurities as well as dissolved moisture & gases from the oil.
During the filtration process, the necessary interlocks provided will avoid malfunctioning of the plant, like
1. High level float switch will stop the inlet pump, to avoid flooding of the degassing chamber.
2. Unless the inlet pump is'ON'the heaters will not be energized.
3. Low level float switch will stop the outlet pump to avoid dry running of the pump
During the filtration process, the moisture meter, installed in the inlet line, will display the moisture content in PPM, continuously, on it's indicator, on the control panel.
Once the desired PPM(moisture)content is achieved, the moisture meter installed in the inlet line, will shut down the plant, automatically.
This plant will also run with Manual Interference means with Manual Operation.

Transformer Oil Filtration Plant

Transformer Oil Filtration Plant

Our oil filtration plants are used to remove impurities from transformer and switchgear oil such as moisture, dirt, air and other gases. This is a `low temperature and high vacuum` principle based equipment as per the International Standards 6034 (1989) and its latest revision. We manufacture plants of variable capacities of 1200 to 25, 000 lph which can be customized to special capacities if required by the clients. This plant takes the impure oil into the system through the inlet ball valve and then pumps it through by a positive displacement pump. A filter prior to this removes solid particles up to 1mm size and magnetic particles. After heating the oil up to 60c it passes through the cartridge filters, where particles up to 5 microns are filtered. A specially designed vacuum chamber removes moisture, air and all the gases with the help of vacuum. The oil falls by way of gravity over the media inside forming a thin film of oil, exposing a larger surface area. The dissolved moisture and gases are evacuated and the oil is ready.
