Is it a problem to operate the pneumatic diaphragm pump frequently?
Thread Content
If it starts and stops once per minute, will the pump get damaged quickly?
There should be no problems, but pay attention to the lubrication of the starting motor, as well as the purity and pressure of the compressed air.
Let me be more specific. This pump is used to transfer the finished product to the filling station. While filling one more bucket and then the next, the outlet valve at the filling station was closed. According to standard design practices, a return pipeline should be installed on the side of the transfer pump so that it isn’t necessary to stop the pump, but in reality, such a design was not used. Therefore, it is necessary to consider stopping the pump during the filling interval. The filling speed is one barrel per minute on average, so the pump has to be turned on and off every minute. I’m not sure if this will damage the diaphragm pump
There won’t be any problems. Because it’s not like a pump driven by an electric motor, where frequent starting can affect electrical components and may cause the pump shaft to break. It’s just that the diaphragm is prone to damage.
There won’t be any problem! Just make sure to regularly lubricate the valve gear to keep the pistons inside it lubricated～
In practice, an approach that involves changing the tank without stopping the pump can be considered
Be sure that lubrication is fine; if there’s a problem, then why start and stop it every minute?
