Product Specifications

Technical details and manufacturing context for Backwash Control Module

Definition
A specialized control module that automates and regulates the backwash process in industrial filtration systems. It monitors system parameters, initiates backwash cycles based on preset conditions, controls valves and pumps during the cleaning process, and ensures proper system reset after completion.
Working Principle
The module continuously monitors differential pressure, flow rates, or time intervals. When predetermined thresholds are reached, it activates the backwash sequence by opening/closing valves, reversing flow direction, and controlling pump operations according to programmed logic. It includes safety interlocks and status monitoring throughout the cycle.
Common Materials
Electronic components, Plastic housing, Copper wiring
Technical Parameters
  • Module dimensions for panel mounting (mm) Standard Spec
Components / BOM
  • Microcontroller
    Processes sensor data and executes control logic
    Material: Silicon
  • Relay Board
    Controls power to valves and pumps
    Material: PCB with copper traces
  • Interface Panel
    Provides user controls and status indicators
    Material: Polycarbonate
Engineering Reasoning
0.5-6.0 bar (7.25-87.0 psi)
8.0 bar (116.0 psi) differential pressure across solenoid valves
Design Rationale: Hydraulic hammer exceeding solenoid valve structural yield strength (316 stainless steel, 290 MPa yield)
Risk Mitigation (FMEA)
Trigger 24V DC power supply voltage drop below 18V DC for >500ms
Mode: Solenoid valve fails to actuate, causing incomplete backwash cycle
Strategy: Implement undervoltage lockout circuit with 20V DC threshold and 100ms hysteresis
Trigger Ambient temperature exceeding 85°C for >30 minutes
Mode: Microcontroller thermal shutdown at 125°C junction temperature
Strategy: Add PTC thermistor with 75°C trip point to disable output drivers
