10 Bar Piston Air Compressor

The piston air compressor is a type of reciprocating air compressor that compresses air to a certain pressure through the reciprocating motion of the piston in the cylinder.

Product Advantages
1. All-copper motor, high speed, fast air intake
2. Original pump head, enlarged exhaust chamber, and lamination process for high strength and excellent heat dissipation
3. Waterproof and explosion-proof, safe body; tight welding for leak-proof safety
4. Noise filter for low-noise operation; absorbs suction noise and filters dust
5. High-quality fan for efficient heat dissipation; enlarged blades for excellent heat dissipation

Scope of Application
Wind-powered tools, rock drills, pneumatic picks, pneumatic wrenches, pneumatic sandblasting, vehicle braking, ventilation in underground passages, metal smelting, food, pharmaceutical industries, using compressed air to stir slurry, pneumatic systems for large marine diesel engines, etc.

Questions and Answers

1. What preparations should be made before starting a piston air compressor?
① Check the lubricant oil level: The oil gauge should be between the minimum and maximum marks. If insufficient, add the appropriate type of lubricant (do not mix different brands/models).
② Confirm the power supply voltage: Match the rated voltage of the air compressor (e.g., if it is 380V three-phase, check that the wiring is correct to avoid phase loss).
③ Check the intake valve: Ensure it is open to avoid starting under pressure.
④ Check the exhaust pipe: Ensure there are no blockages or leaks, and that accessories such as the pressure gauge and safety valve are in good condition.

2. Why is the pressure not rising during operation?

Common four types of problems, troubleshoot in order of priority:

Intake problems: clogged air filter (remove and clean or replace the filter element), intake valve not fully open (check the valve block for sticking);

Seal problems: worn/broken piston rings (causing cylinder air leakage), loose pipe joints (use soapy water to detect leaks);

Exhaust problems: safety valve malfunction (premature pressure relief), worn exhaust valve disc (seal failure);

Motor problems: insufficient motor speed (low voltage or motor failure), belt slippage (adjust belt tension).

3. What should I do if the noise suddenly increases during operation?
First, identify the source of the noise and then address it specifically:
Mechanical friction noise: This could be caused by a lack of oil in the bearings (add grease) or wear between the piston and cylinder wall (check clearance and replace parts if necessary);
Knocking noise: This could be caused by a loose connecting rod bearing (tighten bolts) or a broken valve disc (disassemble the valve housing for inspection);
Vibration noise: This could be caused by loose bolts securing the machine (tighten the anchor bolts) or an unbalanced pulley (correct or replace).
Note: If the noise is abnormal, it is recommended to shut down the machine for inspection to prevent further malfunctions.
