Technical details and manufacturing context for Resin Storage and Metering System

Definition
A critical component within the Modular Transformer Core Assembly and Impregnation System responsible for the safe storage, conditioning, and accurate volumetric or gravimetric dispensing of impregnation resin onto transformer cores prior to curing.
Working Principle
The system typically consists of sealed storage tanks to prevent resin contamination or premature curing. Resin is transferred via pumps through heated lines to maintain viscosity. A metering unit (e.g., positive displacement pump, flow meter, or weigh scale) precisely controls the amount of resin dispensed based on pre-set parameters for the specific transformer core being processed.
Common Materials
Stainless Steel (for tanks and wetted parts), Food-grade plastics (for seals/gaskets), Heating elements
Technical Parameters
  • Storage tank capacity (L) Per Request
Components / BOM
  • Resin Storage Tank
    Holds the bulk supply of impregnation resin, often equipped with agitation and temperature control.
    Material: Stainless Steel
  • Metering Pump/Valve
    Precisely controls the volume or weight of resin dispensed per cycle.
    Material: Stainless Steel, Ceramic
  • Heated Transfer Lines
    Insulated and heated pipes or hoses that transport resin from the tank to the dispensing point, preventing cooling and viscosity increase.
    Material: Stainless Steel, PTFE lining
  • Control Unit
    Electronic system (PLC/HMI) that sets, monitors, and controls dispensing parameters like volume, flow rate, and temperature.
    Material: Electronics, Plastic/Steel Enclosure

Cause: Abrasive particles in resin, improper calibration, or mechanical wear in pump components (seals, pistons, valves)
Maintenance Indicators
  • Visible resin leakage or drips at pump seals, fittings, or tank connections
  • Audible knocking or irregular cycling sounds from metering pumps indicating cavitation or mechanical issues
Engineering Tips
  • Implement strict temperature and humidity control in storage areas, and use nitrogen blanketing in tanks to prevent resin oxidation and moisture absorption
  • Install inline filters before metering pumps, perform regular calibration checks, and use predictive maintenance (vibration analysis, ultrasonic testing) on pump components
