Helium recovery system

Wayeal Helium Recovery System

The helium recovery system mainly consists of high-pressure tanks, low-pressure tanks, compressors, vacuum pumps, valves, pressure sensors, and stainless steel pipelines.

It can perform gross leak detection, helium filling, helium recovery, and other processes on workpieces within the set time.

System composition

Main modules and pipelines

The system is built around tanks, pumping, compression, valves, sensing, and stainless steel pipeline connections.

  • High-pressure tanks
  • Low-pressure tanks
  • Compressors
  • Vacuum pumps
  • Valves
  • Pressure sensors
  • Stainless steel pipelines

Monitoring and replenishment

Pressure, concentration, and automatic helium supply

The system is equipped with helium pressure and concentration monitoring functions, as well as an automatic helium replenishment function.

When the system detects that helium concentration or pressure is lower than the set value, it automatically opens the valve to supplement high-purity helium.

  • Gross leak detection
  • Helium filling
  • Helium recovery
  • Helium pressure monitoring
  • Helium concentration monitoring
  • Automatic helium replenishment

II System Working Principle

Wayeal Helium Recovery System working principle diagram
  1. 1

    V7

    Evacuate the workpiece

    Open valve V7 to evacuate the workpiece under test. After evacuation, close V7.

  2. 2

    V1

    Fill with helium

    Open valve V1 to fill the workpiece with helium. When the specified pressure is reached, close V1.

  3. 3

    V2

    Transfer high-pressure helium

    After leak detection is completed, open V2 so the high-pressure helium inside the workpiece automatically flows into the low-pressure tank, then close V2.

  4. 4

    V3

    Recover remaining helium

    Open V3; the mechanical pump extracts the remaining helium from the workpiece and sends it to the recovery tank.

  5. 5

    V4 + V5

    Compress into the high-pressure tank

    When pressure in the recovery tank rises to the preset value, open V4 and V5 so the compressor compresses helium into the high-pressure tank.

  6. 6

    V6

    Replenish pure helium

    Because 100% recovery is not possible, open V6 to supplement pure helium when pressure or concentration in the high-pressure tank is lower than the specified value.

Important note

Actual efficiency of 98%

Actual efficiency of 98% will be dependent on the product evacuation level prior to helium charge, final helium charge pressure, part pressure level at the completion of recovery, cycle time, and product volume.
