As bombas pneumáticas de diafragma são extremamente confiáveis e robustas, conseguindo atender a uma ampla gama de aplicações dentro da Indústria. Contudo, assim como qualquer equipamento, ela também pode apresentar alguns problemas.
Para te ajudar, separamos alguns dos principais incidentes que podem prejudicar o funcionamento da sua bomba e como resolvê-los.
Correct air intake size
For the pump to be able to deliver all its functionality, it is necessary that the compressed air input is compatible with the performance of that pump. The pump manual provides essential information to ensure the pump performs as expected, including proper air line size.
Presence of ice restrictions on the muffler
Because of its high-speed operation, the pneumatic diaphragm pump may make loud noises in its environment. For this reason, manufacturers recommend installing a silencer add-on.
The speed that compressed air reaches when entering the air valve and passing through the silencer can cause the temperature to drop considerably. For this reason, it is important to periodically check the muffler outlet for the presence of ice. This ice formation can damage the pump, causing it to malfunction. To avoid this problem, you can follow some guidelines:
Reduce pump air pressure;
Use a larger pump for lower speeds;
Use an exhaust pipe to eliminate air in a remote location;
Use an air line heater to ensure a higher temperature;
Use a surge protector and trap to remove condensation.
Easy Troubleshooting Tips for Air Diaphragm Pumps – Part
If a leak is detected in your pneumatic diaphragm pump, it is necessary to verify that the torque used is that recommended by the pump manufacturer. It is natural for certain materials to expand and relax over time, and it is necessary to inspect the seal in order to implement improvements.
Check that the piping is suitable
Just as the air outlet must be compatible with the size of the pump, it is also necessary to check that the piping is adequately sized. These components must be compatible with the size of the pump and the type of fluid being pumped. It is also important to use more flexible piping to prevent leaks as pump vibration increases.
Reduce pump speed
One of the main advantages of the pneumatic diaphragm pump is its self-priming capability. If the air pressure received by the pump is too high, the pump will not be able to draw fluid efficiently. Reducing pump speed helps to reduce inlet pressure and promote superior performance from your pump.
remove the blocks
Some blockages present in your pump's fluid line can affect its performance and impair its operation. Inspecting certain items will help identify possible restrictions and ensure more efficient processes. For that, look for:
clogs in the line;
Excess hose;
Closed valves.
