Equipment Overview
Device Functions and Principles Introduction
Equipment Introduction
The recovery machine is used in conjunction with the vacuum chamber
helium testing equipment to recover the helium after the helium
testing equipment has been tested, pressurize the helium, store it
in a storage tank, and transport it through the pipeline to the
helium inlet of the helium testing equipment.
Structural Features
- Equipment overall Design idea: the design of the equipment fully
consider the advanced, rational, reliability, practicality, safety
and easy maintenance of the equipment.
- To protect the customer's clean test shop from helium
contamination, all connections of the equipment are leak tested
with helium to ensure that no helium leakage occurs throughout the
equipment.
- The system is controlled by PLC. and displays various information
on a touch screen. The screen has a main menu and membrane buttons
and allows for.
- Parameter Setting
- Production process control
- Production status monitoring
- Fault alarm and self-diagnosis
- Manual maintenance
Technical characteristics of the equipment
The specific features are as follows.
1. Helium recovery.
After the recovery system is switched on, it is always in working
condition. When the system receives the recovery signal, the
recovery pump is started and the helium is recovered and stored in
the low pressure tank through the filter and the compressor is
started for high pressure storage in the storage tank when the low
pressure tank reaches the set pressure and the helium concentration
is detected by the concentration helium detector and the recovery
is completed.
2. Automatic helium replenishment function.
When the helium concentration in the recovery system is less than
the set value, the helium is automatically replenished from an
external pure helium cylinder until the helium concentration
reaches the set value.
3. Helium concentration monitoring function.
The recovery system is equipped with helium concentration
monitoring function, when the helium concentration is lower than
the setting, it will automatically start the gas replenishment
function, and if the gas replenishment is insufficient within the
specified time, the system will automatically alarm.
4. Helium filling function.
When the helium inspection host receives the helium charge signal,
high pressure helium is injected into the workpiece from the
storage tank.
5. Filter function
1-stage or multi-stage filters are configured at the outlet of the
storage tank, evacuation pump and air compressor to achieve high
reliability filtration.
Main indicators of the equipment
| Serial number | Projects | Parameters |
| 1 | Size | 2200X2000X2500 mm |
| 2 | Helium recovery rate | ≥90% (helium recovery rate), no external air or foreign matter
mixed into the recovered helium during the recovery process |
| 3 | Crop rate | ≥99% |
| 4 | Energy consumption | 15KW |
| 5 | Helium control concentration range | When the recovered helium concentration is higher than the control
range, the helium supply to the recovery machine will not be
adjusted based on the recovered concentration; when the helium
concentration in the storage tank of the recovery machine is lower
than the helium concentration required by the helium detector, the
helium concentration can be brought up to the required
concentration by replenishing the helium. |
| 6 | Helium concentration control accuracy | ±When the helium concentration is close to the upper limit of the
set value, the helium is not replenished, and when it is close to
the lower limit of the set value, the helium is automatically
replenished to the set concentration. When the helium concentration
recovered is too low and the total amount of gas in the circulating
system continues to increase after replenishing the pure helium
according to the target value of the helium supply, the recovery
machine can automatically discharge the excess gas in the system
through the pipeline to the workshop and alarm to remind |
| 7 | Concentration monitoring | Equipped with automatic online real-time helium concentration
monitor, which can automatically control the helium filling and
provide the equipment principle to guarantee the accuracy higher
than 3%. |
| 8 | Output pressure | 0.05-0.25MPa adjustable |
| 9 | Helium recovery time | Helium recovery time: ≤ 3S |
| 10 | Noise | ≦75 db |
| 11 | Performance | 1 recycling machine with 4 helium detectors |
