Understanding how do double diaphragm pumps work will help us ensure we use them well in all kinds of situations. Here at Shanghai Chongfu, we would like every one of our customers to have all the information they need to use our pumps safely and expertly.
In order to properly operate double diaphragm pumps, we need to understand how they operate. When the pump was activated, it pumped air into one of the cells. This air causes a part — called the diaphragm — to move, which creates suction. This creates a vacuum to draw fluid into the pump. The movement of the other diaphragm causes the liquid to be expelled from the outlet. This allows us to regulate the how quickly and how much liquid is pump by adjusting the air pressure and flow.
The major components of the double diaphragm pump are the air inlet/outlet valves, the diaphragms, and the liquid chambers. Valve that regulates the air entering the pump. The air outlet valve releases excess air pressure. The diaphragms are made of flexible material and act to reciprocatingly move back and forth, causing a suction to be created which sucks the liquid into the pump and then driving the liquid through the pump. The liquid chambers contain and direct the liquid through the pump.
If you begin having issues with your double diaphragm pump, diagnosing and fixing them early on can save you the trouble of downtime and the expense of costly repairs. If the pump is not initializing, look for blockages or leaks in the air inlet valve and the air outlet valve. If the pump isn’t working as it should, try various air pressures and air flow for the answer that fits. If it's making weird noises or vibrating, inspect the diaphragms for wear or damage.
When using a double diaphragm pump, it is important to do so safely since the pump can still cause harm, such as wearing gloves or goggles while using the pump. Respect the manufacturer's instruction for correct usage. Be sure to shut off the pump and release the pressure prior to any maintenance or repair. It’s also crucial to monitor the pump periodically for any signs of wear or damage, and mend any issues that you spot right away.
