Identifying the Compressor Pump Reed Valve
The compressor pump reed valve is a crucial component responsible for maintaining proper airflow and preventing backflow in the air compressor system. Understanding its location and function is essential for effective troubleshooting and repair.
**Locating the Reed Valve:**
The reed valve is typically situated within the pump head or cylinder of the air compressor. It consists of a series of thin, flexible flaps or reeds that are mounted on a valve plate. The reed flaps are designed to open and close in response to pressure changes within the system.
**Components of the Reed Valve:**
| Component | Function |
|---|---|
| Reed Flaps | Flexible flaps that regulate airflow through the valve. |
| Valve Plate | Support structure for the reed flaps. |
| Valve Springs | Keep the reed flaps closed under low pressure. |
**Valve Function:**
As air is compressed within the pump cylinder, pressure builds up. When the pressure exceeds the force of the valve springs, the reed flaps open, allowing the compressed air to flow out of the pump and into the downstream system. When the pressure drops, the reed flaps close again, preventing backflow and ensuring proper operation of the compressor.
Removing the Compressor Pump Cover
The compressor pump cover houses the reed valves, as well as the crankshaft and connecting rod. It’s crucial to take precautions to prevent engine damage when removing the cover.
Safety Measures
- Wear appropriate personal protective equipment, such as safety glasses and gloves.
- Ensure the compressor is unplugged or disconnected from the power source.
- Allow the compressor to cool down completely before handling it.
Physical Dismantling
- Locate the compressor pump bolts, typically situated around the perimeter of the cover.
- Using a wrench or socket set, carefully loosen and remove the bolts. Avoid overtightening or stripping the threads.
- Gently pry the cover away from the compressor housing. If the cover is stuck, tap its edges lightly with a rubber mallet or soft hammer.
- Take note of the orientation of the cover and ensure it is reinstalled in the same position.
Inspection and Removal
- Once the cover is removed, inspect it for any damage or wear. Look for cracks, breaks, or bent sections.
- Locate the reed valves, which are thin, flexible plates attached to the cover or valve plate. Inspect them for cracks, tears, or warping.
- Use a small screwdriver or pliers to gently pry the reed valves away from the cover. Take care not to damage the reed valves or the valve plate.
