Huazheng Manufacture HZSF-15-50 SF6 Gas Recovery Device

This SF6 gas recovery device features an oil compressor imported from Italy. The compressor is specifically designed for SF6 gas recovery, with a displacement capacity of 6.5 m³/h and a maximum output pressure of 4.5 MPa (though the device pressure is controlled at 3.8 MPa). As a high-pressure compressor, it offers low power consumption, which significantly reduces the volume and weight of the SF6 recovery device.

Operating Instructions

Operating Instructions

1.Power Connection and Startup

Insert the standard power cord into a power socket that meets the requirements. Turn on the power switch, and the cooling fan of the compressor will start to run.

Note: This operation must be performed at all times. Even after work is completed, the main power supply should remain connected for at least 1 minute to ensure sufficient heat dissipation.

2.Adjusting Suction Pressure

Ensure the external pipeline connections are correct. Adjust the suction pressure reducing valve of the compressor to ensure that the pressure at the suction port is below 0.5 MPa. This adjustment allows the compressor to start normally and enter the working state.

3.Starting and Stopping the Recovery Device

Press the green start button to activate the recovery device. To stop the device, press the red stop button.

4.Overpressure Protection

If the outlet pressure exceeds 3.8 MPa before shutting down, the internal protection mechanism of the compressor will automatically stop the compressor to prevent damage.

Important Instructions

1.Particle Content in Recovered Gas

To protect the compressor from particle pollution and wear, please install a particle filter (with a pore size less than 5 µm) on the inlet pipeline.

2.Mixed Gas Content in Recovered Gas

Do not use this SF6-specific compressor for any other gases. Before using the equipment, remove all gases inside using the vacuum method, reducing the pressure to 0.5 mbar.

3.Power Supply and Wiring

Ensure the correct use of power supply and wiring. If the compressor is used continuously for extended periods or operates under high pressure for long durations, the overheat (overcurrent) protection switch will automatically cut off the compressor’s control power. To restore operation, manual reset is required. Therefore, position the compressor so that the overheating protection switch is easily accessible for manual resetting.

4.Safety and Maintenance

Do not disassemble pressure equipment unless you are a professional. Avoid installing the equipment in locations where it may be struck or damaged. No modifications are allowed.

Note: Only our professional engineers or individuals trained by us are authorized to perform maintenance and repairs.
