Working Principle of Leynow Piston Oil-free Air Compressor

  • The Leynow piston oil-free air compressor is a positive displacement reciprocating piston model. The motor drives the crankshaft-connecting rod mechanism, driving the piston to reciprocate inside the cylinder.

  • When the piston moves downward, the cylinder volume increases, the intake valve opens, and ambient air is drawn into the cylinder chamber;

  • When the piston moves upward, the cylinder volume is compressed, the air pressure in the cylinder increases, the exhaust valve opens, and compressed air is output from the exhaust port;

  • The suction-compression-exhaust cycle is completed repeatedly to generate positive pressure compressed air. The pump chamber relies on the self-lubrication of the piston cup seal, requiring no lubricating oil, and the output gas is free of oil mist.

  • Note: Actual output pressure and flow are affected by external factors such as pipeline, filter resistance, ambient temperature, and intake conditions.

Technical Information & Materials

Compiled technical reference materials related to vacuum pumps for selection, equipment commissioning, and troubleshooting.

Project Selection Reference Suggestions
  • Confirm core indicators: required ultimate vacuum, actual pumping volume;
  • Clarify the extracted medium: water vapor, dust, corrosive gases, etc., to determine whether filtration, condensation, or explosion-proofing is needed;
  • Confirm the usage environment: indoor/outdoor, on ships, high temperature and humidity, dust environment;
  • Usage mode: intermittent use or long-term continuous operation;
  • Standalone equipment or a complete central vacuum station.

Selection and Usage Tips:

  • For selection, prioritize confirming: required pressure, actual flow rate, power supply conditions, and installation space. Do not only look at power size;

  • When extracting air containing dust and water vapor, it is recommended to install an intake filter at the front end to protect the piston cup seal;

  • The piston oil-free compressor prioritizes intermittent working conditions; long-term 24h full-load uninterrupted continuous operation is not recommended; for high-frequency use, it is recommended to add intermittent start-stop control;

  • Output pressure and flow are affected by pipeline resistance, intake filtration, and ambient temperature;

  • The piston cup seal is a consumable wearing part and needs regular inspection and replacement according to working conditions.

Customer FAQs

Focusing on selection differences, AC/DC power supply, continuous operation, and wearing parts, supporting non-standard customization answers.

Are the hardware components of household, medical, industrial, and laboratory versions completely the same?

The basic piston structure is the same, but the motor, pressure, and flow parameters are adapted. Direct cross-scenario use is not recommended; working condition parameters need to be verified.

Are the output performances of DC and AC models the same?

For the same power level, the performance indicators are similar; the main difference is the power supply method; DC is suitable for mobile vehicle-mounted use, and AC is suitable for fixed mains power scenarios.

Can the oil-free compressor work continuously for 24 hours without stopping?

This series is mainly for intermittent working conditions; for high-frequency continuous use scenarios, it is recommended to implement start-stop intermittent control to reduce wearing part consumption.

Which parts are wearing parts?

The piston cup seal is the main consumable; the intake filter element needs regular cleaning or replacement.

Can special voltage, interfaces, and installation dimensions be customized?

You can submit working condition requirements to evaluate customization feasibility and contact the business department to obtain a solution.
