Performance of AODD PUMP

The AODD PUMP is a double-suction diaphragm pump chamber. Of course, there are also single-chamber pneumatic diaphragm pumps, but the flow and head are definitely not as large as the double-suction diaphragm pump. The Air Operated Double Diaphragm Pump has a long service life. If the internal membrane is used If the quality of the film is good, the service life of the pneumatic diaphragm pump can reach more than 10 years. The advantage of this pump will not stop and never jam. It can transport not only flowing liquid media, but also difficult-to-flow media, and even dust , It has the comprehensive advantages of self-priming pump, submersible pump, mud pump, canned motor pump, etc. It can be described as a powerful diaphragm pump. It is mainly driven by compressed air and driven by general air compressors. Both liquids and liquids with particles can be pumped clean. Because it does not have a motor, it can be used safely in flammable and explosive situations. It can also be used to immerse the pump in a liquid medium. It will not damage the pump when idling. Since there are no rotating parts and shaft seals, it is a leak-proof pump.

1. No need to irrigate and divert water, suction lift up to 7m, head up to 70m, outlet pressure ≤ 0.8Mpa

2. The flow is spacious and the passing performance is good, allowing large particles up to 9.4mm in diameter. When pumping mud and impurities, there is little wear on the pump:

3. The head and flow can be adjusted by the air source pressure (the air source pressure is between 0.1-0.8Mpa);

4. Working environment range: 5-65℃; conveying medium range (-20℃-150℃);

5. The pump has no rotating parts and no shaft seal. The diaphragm completely separates the pumped medium from the moving parts and working medium of the pump, and the conveyed medium will not leak outward. Therefore, when pumping toxic, volatile and corrosive media, it will not cause environmental pollution and endanger personal safety;

6. No need for electricity, safe and reliable to use in flammable and explosive places;

7. Can be submerged in the medium to work;

8. It is convenient to use, reliable in operation, and only needs to open and close the gas valve for starting and stopping. Even if there is no medium for a long time due to unexpected conditions or sudden shutdown, the pump will not be damaged. Once overloaded, the pump will automatically stop, with self-protection performance, when the load returns to normal, it can automatically start operation.

9. Simple structure with few wearing parts. The pump structure is simple, easy to install and maintain. The medium delivered by the pump will not come into contact with moving parts such as the pump air valve, connecting rod, etc., and the performance of other types of pumps will not gradually decrease due to the wear of rotors, pistons, gears, blades and other parts;

10. It can transport more viscous liquids (viscosity below 10,000 centipoise);

11. The pump does not need lubricating oil, even if it is idling, it has no effect on the pump. This is a major feature of the pump.

How to choose Air Operated Double Diaphragm Pump in different occasions?

Air Operated Double Diaphragm Pump is a new type of pump. It has a wide range of uses. It is used in all areas of life. It has no motor itself, so it is very safe. It can be used in various flammable and explosive occasions. It can be used for diaphragm pump. Conveying of materials.
Diaphragm pumps are also made of different materials for different purposes, such as cast iron, aluminum alloy, engineering plastics, stainless steel, and a better design, lining with fluoroplastics… etc., which can meet different requirements. For the process requirements of the manufacturers, let’s interpret the application of different materials for you to explain how the Chiyi pneumatic diaphragm pump is just like choosing the material in different situations! Cast iron material, not acid and alkali resistant, suitable for sewage, filter press, etc., as long as it is not corrosive, it can be used. Aluminum alloy material is characterized by light weight, easy operation, and convenient mobility. Chiyi aluminum alloy diaphragm pump with PTFE diaphragm can be used in rubber factories, resin factories, glue and paint factories, paint factories, and printing factories. Pneumatic diaphragm pump for conveying! Chiyi stainless steel pneumatic diaphragm pump can be used in food factories. It can transport jam, chocolate sauce, peanut butter, any flowable and can have a certain viscosity, but as long as the viscosity is within a certain range, it can be carried out with a pool pneumatic diaphragm pump. For conveying, the better material can be 304 stainless steel and 316 stainless steel!

How to use Air Operated Double Diaphragm Pump more handy

Air Operated Double Diaphragm Pump is mainly composed of transmission part and diaphragm cylinder head. The transmission part is a driving mechanism that drives the diaphragm back to agitate. Its transmission forms include mechanical transmission, hydraulic transmission and pneumatic transmission. Among them, hydraulic transmission is widely used.

The working part of the AODD PUMP is mainly composed of a crank connecting rod mechanism, a plunger, a hydraulic cylinder, a diaphragm, a pump body, a suction valve and a discharge valve, etc., among which a drive mechanism and a reciprocating plunger are composed of a crankshaft connecting rod, a plunger and a hydraulic cylinder The pumps are very similar. When the diaphragm pump is working, the crank connecting rod mechanism is driven by the electric motor to drive the plunger to reciprocate. The movement of the plunger is transmitted to the diaphragm through the working fluid (usually oil) in the cylinder, causing the diaphragm to move back and forth.

The cylinder head of the pneumatic diaphragm pump is mainly separated by a diaphragm to separate the conveyed liquid from the working liquid. When the diaphragm moves to one side of the transmission mechanism, the pump cylinder works under negative pressure and sucks in the liquid. When the diaphragm moves to the other side , The liquid is discharged. The liquid to be delivered is separated from the working fluid by the diaphragm in the pump cylinder, and only contacts the pump cylinder, suction valve, discharge valve and the inner side of the diaphragm, without contacting the plunger and sealing device, which makes the cylinder Important parts such as plugs work completely in oil medium and are in good working condition.

Each of the two symmetrical working chambers of the pump is equipped with a diaphragm, which is connected by a central link. Compressed air enters the air distribution valve from the air inlet of the pump, and the compressed air is introduced into one cavity through the air distribution mechanism to push the diaphragm in the cavity to move, while the gas in the other cavity is discharged. Once the end of the stroke is reached, the air distribution mechanism automatically introduces compressed air into another working chamber, pushing the diaphragm to move in the opposite direction, so that the two diaphragms reciprocate continuously and synchronously. In the figure, the compressed air enters the valve to make the diaphragm move to the right. The suction of the chamber causes the medium to flow in from the inlet, pushing the ball valve into the chamber, and the ball valve is blocked by suction; the medium in the chamber is squeezed. Push open the ball valve to flow out from the outlet, and at the same time lock the ball valve to prevent flow, so that the medium is continuously sucked in from the inlet and discharged from the outlet.

The diaphragm must have good flexibility and good corrosion resistance (interpretation: refers to decay, disappearance, erosion, etc.) performance, usually made of polytetrafluoroethylene, rubber and other materials. The pot bottom-shaped parts with meshes on both sides of the diaphragm are installed to prevent the diaphragm from locally deforming too much, and are generally called diaphragm restrictors. The pneumatic diaphragm pump has good sealing performance and can easily achieve leak-free operation. It can be used to transport acid, alkali, salt and other corrosive liquids and high viscosity liquids.

Regardless of the type of pneumatic diaphragm pump actuator, its output force is the effective force used to overcome the load (mainly refers to the unbalanced force and unbalanced moment plus friction, sealing force, gravity and other related forces). Therefore, in order to make the diaphragm pump work normally, the equipped actuator must be able to produce enough output force to overcome various resistances, to ensure a high degree of sealing and the opening of the valve (function: control component).

For double-acting pneumatic, hydraulic and electric actuators, there is generally no return spring. The magnitude of the force has nothing to do with its running direction. Therefore, the key to selecting an actuator (explanation: an important part of a metaphor) is to understand the output force and the motor’s rotational torque. For single-acting pneumatic actuators, the output force is related to the opening of the valve (action: control component), and the force appearing on the diaphragm pump will also affect the motion characteristics, so it is required to establish a force balance across the opening range of the diaphragm pump.
