As a high-precision detector equipment, helium mass spectrometer is widely used in air tightness testing and leak detector. Its excellent sensitivity enables it to accurately detect tiny gas leaks. However, during long-term use, the equipment may fail, affecting the accuracy of the test results. Understanding the common faults of helium mass spectrometers and their troubleshooting methods is essential to ensure the normal operation and detector accuracy of the equipment.
First of all, the failure of the helium mass Leak spectrometer system to start is one of the common faults. The reason may be unstable power connection, circuit failure or switch damage. When solving this problem, first check whether the power connection is stable and make sure that the socket and power cord are not damaged. If there is no problem with the power supply, you need to check whether the power switch is working properly. If there is any damage, it should be replaced in time. In addition, the fuse inside the instrument may be blown, and it is also necessary to check and replace the fuse.
Secondly, abnormal signal strength is also a common fault. Abnormal signal strength is usually caused by probe or sensor failure, or the gas leakage source is small, making the signal difficult to detect. At this time, you first need to check whether the connection between the probe and the instrument is loose and whether the connector is stable. If there is no problem, it may be that the internal sensor is damaged, and a professional is required to repair or replace the sensor. If the signal is too weak, the operator can also enhance the signal detector capability by adjusting the sensitivity or gain setting of the instrument.
In addition, it is also a common problem that helium leaks cannot be detected. This problem is generally caused by insufficient helium flow, unclear leak points, or improper placement of the probe. When solving this problem, first check the pressure of the helium cylinder to ensure that the helium supply is sufficient. If the cylinder is empty, it needs to be replaced in time. At the same time, the position of the probe should be readjusted to make it closer to the leak source to ensure that the detector distance between the probe and the leak point is appropriate. In addition, the operator should also ensure that the test area is completely sealed to prevent external air from affecting the test results.
Finally, a failure in the vacuum system may also affect the normal operation of the helium mass spectrometer. A failure of the vacuum pump or a loose pipe connection may cause the equipment to fail to operate normally. At this time, it is necessary to check whether the vacuum pump is operating normally and check the tightness of the pipe to ensure that there is no leakage. If there is a problem, the pump oil needs to be replaced or the pipe repaired.
By regularly checking the key components of the equipment, such as the power supply, probe, gas supply and vacuum system, operators can effectively eliminate common faults and ensure the continuous and stable operation of the equipment. Mastering these troubleshooting skills will provide important guarantees for daily maintenance and troubleshooting.
