5. Principis de funcionament

The diaphragm set TCG22EAS is integral to the proper functioning of a small engine carburetor, particularly in two-stroke engines found in brush cutters. It performs two primary functions:

• Bomba de combustible: One diaphragm acts as a fuel pump, drawing fuel from the tank to the carburetor's metering chamber. Engine vacuum and pressure pulses cause the diaphragm to flex, creating a pumping action.
• Metering Diaphragm: Another diaphragm (or part of the same one) senses the pressure difference between the carburetor's venturi and the metering chamber. This pressure difference controls a metering lever and needle valve, regulating the amount of fuel delivered to the engine based on engine speed and load.

A properly installed and functioning diaphragm set ensures consistent fuel delivery, leading to reliable starting, smooth idling, and optimal power output from your brush cutter.

6. Manteniment

Regular maintenance of your brush cutter's fuel system, including the diaphragm set, is crucial for longevity and performance.

• Qualitat del combustible: Always use fresh, clean fuel mixed according to the brush cutter manufacturer's specifications. Stale or contaminated fuel can degrade diaphragms and gaskets.
• Filtre de combustible: Regularly inspect and replace the fuel filter in the fuel tank to prevent debris from reaching the carburetor and damaging the diaphragm.
• Emmagatzematge: When storing the brush cutter for extended periods, drain the fuel tank and run the engine until it stops to clear the carburetor of fuel. This prevents fuel from gumming up and hardening the diaphragm.
• Inspecció: Periodically inspect the carburetor for any signs of fuel leaks around the diaphragm covers. If leaks are present, the diaphragm set may need replacement.
