Helium Leak Detector Maintenance Guide

Maintenance should cover vacuum pumps, seals, gas path, reference leaks, fixtures, and operation records to reduce background problems and downtime.

Key Points

Daily maintenance should cover vacuum system, gas-path cleanliness, fixture sealing, and reference leak response.
High background, slow response, or poor repeatability should be checked quickly.
High-frequency production lines should keep inspection forms, spare parts, and maintenance records.

Customer Concern

When a leak testing system becomes unstable, the cause may not be the detector itself. Gas supply, fixtures, seals, helium background, or operating habits may also affect the result.

Selection Framework

Daily checkGas supply, vacuum status, background value, fixture sealing, alarm records

Periodic maintenanceVacuum pump, filters, seals, gas fittings, reference leak

TroubleshootingHigh background, slow response, false alarms, lower repeatability

Record controlMaintenance time, symptoms, action taken, retest result

Build daily inspection habits

Check vacuum status, background value, gas pressure, fixture sealing, and reference leak response before startup, changeover, and batch production. A fixed checklist helps reduce missed items.

Watch wearing parts and cleanliness

Seals, filters, gas fittings, and fixture contact surfaces may wear or become contaminated over time. Cleaning, replacement, and retesting help keep detection consistent.

Do not only adjust parameters

If background rises, response slows, or false alarms increase, do not only adjust thresholds. Check helium background, vacuum status, gas-path contamination, fixture sealing, and parameter settings step by step.

What to prepare for service support

When contacting service support, provide equipment model, fault screenshot, recent maintenance record, part information, and retest result. DROIDE SHANGHAI can support maintenance advice, spare parts discussion, and technical support.

FAQ

How often should maintenance be done?

The interval depends on use frequency, site environment, and equipment status. High-frequency lines should use a fixed checklist.

What can cause high background?

Possible causes include helium in the environment, gas-path contamination, vacuum condition, fixture sealing, or parameter settings.

What is the role of a reference leak?

A reference leak helps check equipment response and whether the system is operating within a normal range.

Need a testing solution discussion?

DROIDE SHANGHAI can support model selection, parameter review, fixture planning, vacuum system configuration, and on-site delivery discussion.
