Because of their simplicity, air operated double diaphragm pumps (AODD Pumps)are great for transfer applications. To achieve maximum performance, it is important to properly install and operate your pump. These six easy fixes will help you troubleshoot and fix common problems when your AODD is not working properly during installation and operation.
1.To Check The Air Inlet Size And Pressure.
A small airline is the most common error with AODD pumps. To operate at its best, the pump requires compressed air. An airline that is too small will deprive it of the fuel it needs. Larger AODD pumps (one-inch and more) require more compressed and longer air lines than their smaller counterparts. For the correct size air line for your pump, refer to the manufacturer's instructions and operation manual. It is a good rule of thumb to match the size of the air line hose to the size of the inlet port on AODD pumps. Explore the latest AODD Pumps at Antlia Engineering Works. They are the AODD Pump Suppliers Globally.
Your pump's performance can also be optimized by adjusting the inlet pressure. Diaphragm pumps work in a 1:1 ratio. The pump's inlet pressure is directly proportional to the pump's outlet pressure. 100 psi is the target outlet pressure for a 50 gpm 1 inch pump. The pump's inlet pressure must also be greater than or equal to 100psi.
The outlet fluid pressure is affected by fluid viscosity, system back pressure, and fluid viscosity. Too little back pressure can cause the pump to run slower and the ball checks may not be as quick. If the fluid pressure exceeds the air pressure, the pump may stall. An air regulator is required to regulate the incoming pressure to ensure that an AODD pump performs at its best. An air regulator and the correct size air line will resolve most of the problems associated with AODD pump installation.
2.Check for Muffler Icing and Restrictions
Mufflers can be installed on AODD pumps and are recommended because they can produce high decibel levels at full speed. To operate the pump's air motor, compressed air is needed. Rapid temperature changes are caused by the compressed air entering the valve. It is then channeled through the pump's center section and exhausts through the muffler. The muffler exhaust temperature is below freezing and can lead to icing issues. This is more prevalent in environments with high humidity. Looking for AODD Pump Manufacturers In India.
Visit Antlia Engineering works, they manufacture all types of AODD Pumps.
If your pump is acting erratically, your inlet air contains high levels of moisture, or you can see the front of your muffler, these are indicators that your pump has icing issues. These solutions can help you eliminate icing issues and improve your pump's efficiency.
Pump the air pressure down
To operate at a lower speed (i.e.,. lower air pressure)
An exhaust port tube allows you to exhaust the air to remote locations
To collect condensation, add an air filter and a water catcher to your system.
To raise exhaust air temperature above freezing, install an air heater
To adjust the pressure dew point temperature, use an air compressor dryer
3.Checking Sealing Surfaces for Leaking
Leakage issues can occur with all types of pumps. These tips will ensure that your fluids remain in the pump and not the ground.
Follow the bolting pattern's illustration and torque the pump to the manufacturer's specifications.
When servicing your AODD pump, replace all PTFE o rings. Although PTFE can be used in many applications, it is not capable of returning to its original form after being compressed.
You can reduce the risk of leakage by properly torquing your pump according to the manufacturer's specifications and ensuring that sealing o-rings are replaced during service.
4. Ensure proper tubing and piping sizes
The flow rate of fluid required will determine the diameters of the pump's inlet and outlet ports. The size of the outlet and inlet hoses must be equal. This is a major concern because of the potential for cavitation, as well as the higher repair frequency and increased maintenance costs.
A pump that is 1 inch tall has a 1/2-inch inlet hose attached. The pump will not be capable of operating at its maximum capacity without cavitation. As the fluid viscosity increases, this risk is greater. To avoid cavitation, a pump of 1 inch should have an outlet and inlet hose of 1 inch. This will prevent costly and frequent repairs.
AODD pumps should have flexible inlet and outlet connections. This is preferable to hard plumbed installations. As the pump speed increases, vibration increases. Vibration increases with pump speed. This increases the possibility of hard-plumbed connections being loosened, which can lead to leakage.
5. PRIME - LOWER THE PUMP
AODD pumps are a popular choice for applications that require self-priming. The AODD pumps draw fluid by creating a low-pressure zone within the fluid bowls. This is less than the atmospheric pressure (14.7 psi). If the air pressure is too high, the pump will not changeover quickly enough to allow the fluid to flow into it.
This is solved by using the air regulator to reduce the air pressure entering an air valve and slow down the pump. The pump speed can be reduced to ensure that the fluid supplied has sufficient time to reach the pump. After this, the pump can operate at a faster speed by increasing the air pressure.
6. CLEAR ALL FLUID LINE RESERVATIONS
Clearing any fluid line restrictions is the final step in ensuring optimal pump performance. Limitations can lead to increased maintenance, pressure loss and potential cavitation. This issue can be fixed by removing the following:
Valves that are partially or fully closed
Line kinks or clogs
Too many hoses or too long a distance
These six steps will resolve most of the problems associated with AODD pumps. This will allow you to produce more and not spend time trying to fix it. If you need more help troubleshooting and repairing your AODD pump contact one of our experts.
