As a giant in the field of vacuum technology, Ulvac's HELIOT series (700/710/900) helium mass spectrometer leak detector has established itself as a core detection equipment across critical industries such as new energy, semiconductors, and precision manufacturing. This is largely due to its ultra-high pumping speed, intuitive flat-panel operating interface, and robust adaptability to complex working conditions. The sophisticated internal Q-pole quadrupole mass spectrometry analysis tube and intricate gas path design demand an exceptionally high level of professionalism in maintenance and repair.

To address common pain points faced by enterprises, such as calibration failures, decreased sensitivity, and controller malfunctions, and to prevent irreversible damage to equipment performance often caused by non-professional repairs, we are proud to officially launch our specialized professional maintenance service for Ulvac's exclusive helium mass spectrometer leak detectors. This service offers targeted solutions and comprehensive, full-process guarantees to ensure your production operations remain efficient and uninterrupted.

Core Service Advantage: Targeting Pain Points, Professional Adaptation

1. Precise Coverage Across the Entire Series, Targeted Fault Resolution

   Our service specifically focuses on core HELIOT models, including the 700 and 900 series, developing standardized solutions for typical faults. We precisely handle issues like calibration failures ("Sensitivity Low" alarms), persistently high background values, difficult start-ups, and unresponsive touchscreens. We delve deep to resolve unique problems such as ion source carbon deposition, blockages in standard leak holes, aging solenoid valve seals, and controller communication failures. This specialized approach ensures we avoid the "treating symptoms without addressing the root cause" pitfalls common with generic maintenance.

2. Original Factory Level Repair of Core Components, Performance Restored to Factory Standards

   Leveraging our profound understanding of Ulvac equipment architecture, we provide chip-level repair services. This includes chemical cleaning and filament component replacement for ion sources, calibration and replacement of standard leak holes, updating O-ring seals for solenoid valves, and repairing touchscreens for flat-panel controllers. All core replacement parts adhere to original factory specifications, guaranteeing that the equipment's sensitivity, pumping speed, and detection stability are fully restored to their original factory performance levels after maintenance. For more details on original factory level repair, visit our website.

3. Full Lifecycle Services, Covering Repair / Maintenance / Relocation

   Beyond fault repair, we offer customized preventive maintenance services designed to meet original factory standards. This includes ion source maintenance every 6-12 months, mechanical pump oil and filter replacement every 3-6 months, seal replacement every 12 months, and molecular pump spot checks every 12-24 months. For equipment relocation needs, we provide a comprehensive service that covers oil discharge locking, shockproof packaging, static debugging, and full-scale calibration. This meticulous process prevents potential molecular pump damage or quadrupole displacement during transit.

4. Efficient Response + Resource Support to Reduce Downtime Losses

   We offer 24-hour emergency response, providing flexible service modes including on-site repair for large production line equipment and delivery repair for portable models. A detailed testing report is issued within 24 hours of receiving your equipment. We also provide a complimentary "Ulvac Leak Detector Fault Code Quick Check Manual" to help enterprises rapidly troubleshoot simple faults. Furthermore, we maintain a ready stock of HELIOT series original parts, significantly reducing repair turnaround times and minimizing costly downtime.

Successful Case: HELIOT 900 Calibration Fault Repair for New Energy Battery Factory, 24-Hour Production Line Restoration

Customer Background

A leading domestic new energy battery enterprise experienced a critical issue with their Ulvac HELIOT 900 helium mass spectrometer leak detector, a core testing device on their cell packaging production line. The automatic calibration suddenly failed, displaying a persistent "Sensitivity Low" prompt, and the helium background value soared to 3.2E-7 mbar·L/s. This rendered the equipment incapable of meeting the precision requirements for cell sealing detection, forcing three production lines to halt, incurring a potential loss exceeding 25,000 yuan per hour.

Fault Diagnosis and Maintenance Process

• Emergency Response: Within two hours of receiving the report, a specialized engineer was dispatched to the site. Utilizing dedicated diagnostic tools, the root cause was identified: the ion source had severe carbon deposition due to prolonged detection of oil-contaminated workpieces, leading to a decrease in emission current. Concurrently, the internal standard leak hole was blocked by micro-dust.
• Deep Repair: The equipment was carefully transported to our dust-free maintenance workshop. The ion source underwent thorough disassembly and chemical cleaning, followed by the replacement of its filament components with original specification parts. The blocked standard leak hole was professionally cleared and recalibrated, and aging O-ring seals for the air intakes were replaced.
• Accurate Calibration: Following the repair, a comprehensive, full-scale performance test and calibration were conducted. The equipment parameters were meticulously compared against original factory standards, confirming that all indicators, including vacuum pumping speed, response time, and detection accuracy, met or exceeded requirements.

Repair Effectiveness

• The equipment malfunction was completely eliminated, with calibration passing successfully on the first attempt. The helium background value stabilized below 6.8E-9 mbar·L/s, fully satisfying the stringent requirements for cell sealing detection.
• From the initial fault report to the full restoration of the production line, only 24 hours elapsed, cumulatively reducing the enterprise's potential losses by over 600,000 yuan.
• We subsequently developed a customized plan for quarterly spot checks and annual deep maintenance for the client. The equipment has since operated stably without any faults for eight consecutive months, and the consistency of testing data has improved by 30%.
