1. Preparation before adjustment
Stop feeding and discharging liquid, stabilize tank liquid level; open the switch inspection cover on the side-mounted linkage assembly, prepare screwdriver and ruler.
2. High/low level calibration method
- Adjust low-level cutoff point: Inject liquid slowly until reaching required low setting height. Loosen the locking screw on the linkage arm, shift the float connecting lever up or down to trigger the contact switch action (ON/OFF switching). Fasten the screw after fixed position.
- Adjust high-level cutoff point: Continue filling liquid to target high level. Modify the upper limit stopper or toggle bracket of the linkage mechanism until the upper contact acts reliably, then lock the positioning fastener.
3. Fine-tuning stroke clearance
- Shorten linkage swing travel for narrow level differential; lengthen swing distance to enlarge the gap between high and low action points.
- Avoid excessive tightness of connecting rod to prevent float jamming caused by thermal expansion or medium scaling.
4. On-site verification test
Drain and refill liquid twice repeatedly, check contacts switch at preset high/low liquid level consistently. If action deviates, repeat minor fine-tuning on linkage position.
5. Post-adjustment work
Reinstall protective cover, restore normal tank feeding operation and track running status for short-term inspection.
Key note
For corrosive or low-temperature medium equipment, adjust at ambient temperature; no forced bending on linkage arm during calibration.
