The mechanical pump of the helium mass spectrometer leak detector has sufficient mechanical pump oil to ensure smooth connection of the molecular pump, mechanical pump, and high-altitude components inside the body, with no damage to the power line and good grounding. The helium mass spectrometer leak detector should be placed steadily and not tilted, and there should be a layer of anti-static cloth on the bottom surface of the helium mass spectrometer leak detector. As for how to pressurize the helium device in the tank, you can operate it from the following three aspects:
The external connection sequence of the pressurized helium device in the pressurized tank: Write the order of connection of the external conditions of the equipment, operation methods, specific parameters, etc.
1. Connect the pressurization tank, resistance vacuum gauge, vacuum pump, and helium cylinder as required.
2. Check if the sealing ring of the pressurized tank is damaged and if the inlet and outlet valves of the pressurized tank cannot be closed; Is there enough pump oil in the vacuum pump, and is the gas control valve knob in the closed position; Is there any leakage in the pressure reducing valve of the helium cylinder.
3. After confirming that all necessary precautions are correct, you can connect the power supply to power on.
