Helium Recovery System

Helium Recovery System

Product Introduction:

Helium recovery system is to recover and reuse the used helium, which can reduce production costs, save energy and improve economic benefits.

    Calibration Certificate(cost additional)
  • Model Number :

    HCTE0055
  • Price :

    Negotiable
  • Delivery Time :

    90 days
  • Payment Terms :

    L/C, T/T

Operation Flow:

Operator places the workpiece on the conveyor line, attaches the quick-connect fitting, and starts the line. (Workpiece sealing fittings and male quick-connect fittings are provided by Haier.)

High-pressure air pre-test: Injects 5MPa of compressed air into the workpiece to detect major leaks. Monitors pressure variation within a set time interval to determine leak status. Qualified workpieces proceed to the next step; unqualified ones trigger an alarm.

Vacuum evacuation: Applies vacuum to qualified workpieces from the major leak test. Upon successful evacuation, automatically fills with helium. Unsuccessful evacuation triggers an alarm.

Helium filling: Fills evacuated workpieces with 0.8-1.2MPa of helium (adjustable above 70% concentration). Qualified workpieces proceed; unqualified ones trigger an alarm.

Leak detection: Places helium-filled workpieces in a leak detection chamber and uses a helium mass spectrometer with a suction probe to identify potential leaks.

Helium recovery: Recovers helium from the workpiece using a vacuum method at the recovery station for reuse. If the internal pressure is below the set limit, an alarm is triggered.

Data recording: The system records the number of defects and helium refills for each type of issue.

 

Product Features:

High-pressure Nitrogen Leak Detection: Primarily consisting of pressure sensors, solenoid valves, and piping, it monitors pressure changes to achieve major leak detection.

Evacuation System: Composed mainly of vacuum pumps, vacuum gauges, solenoid valves, and piping, it can evacuate air from the workpiece to ensure helium purity.

Helium Filling System: Primarily consisting of pressure sensors, solenoid valves, and piping, it can fill helium into the workpiece at a set pressure.

Recovery System: Integrated with compressors, sensors, solenoid valves, piping, vacuum pumps, helium concentration meters, and gas storage tanks, it can recover and store helium. When the concentration falls below a set value, it alarms and automatically replenishes helium. Additionally, it is equipped with a pressure gauge to monitor recovery pressure.

Electrical Control: Utilizing touch screen controls, it enables the setting of operational parameters (such as leak detection time and pressure), work status monitoring (providing real-time feedback on equipment status), fault alarming, and manual maintenance functions.
