Pneumatic Model – Insufficient Pressure / Weak Downstroke
2026-08-06 12:30
| Step | Operation | Criterion |
|---|---|---|
| Step 1: Check Compressor | Read the output pressure gauge on the compressor | Below 0.4MPa → insufficient pressure, increase compressor output to above 0.6MPa |
| Step 2: Check Air Hoses | Apply soapy water to all joints and look for bubbles | Bubbles appear → air leak, tighten joints or replace hoses |
| Step 3: Check Pressure Regulator | Check the regulator setting on the machine | Below 0.4MPa → adjust to 0.5-0.6MPa |
| Step 4: Check Cylinder | Listen for abnormal noise or air leakage during cylinder operation | Hissing sound → cylinder seal ring is worn, contact manufacturer for seal replacement |
One-Sentence Summary: It's always one of three things – weak compressor, leaking air hoses, or improper regulator adjustment.
Prevention: Check air hose joints with soapy water weekly. Drain the compressor regularly (moisture in compressed air will corrode the pneumatic system).
