Precautions for using AODD PUMP

Precautions for using AODD PUMP:
Pneumatic diaphragm pump is a positive displacement pump that uses compressed air as its power to change the volume through the reciprocating deformation of the diaphragm. Its working principle is similar to that of a plunger pump.
Pay attention to the following points when using a pneumatic diaphragm pump to operate:

Ensure that the largest particle contained in the fluid does not exceed the maximum safe passing particle diameter standard of the pump.
The intake pressure should not exceed the maximum allowable working pressure of the pump. Compressed air higher than the rated pressure may cause personal injury and property loss and damage the performance of the pump.
Ensure that the pump pressure piping system can withstand the highest output pressure reached, and ensure the cleanliness and normal working conditions of the driving air system.
Electrostatic sparks may cause explosions, resulting in personal injury and death accidents and property losses. If necessary, use a wire with a large enough cross-sectional area to properly and reliably ground the ground screw on the pump.
Grounding requirements comply with local laws and regulations and some special requirements on site.
Tighten the pump and all connecting pipe joints to prevent electrostatic sparks from being generated due to vibration, impact and rubbing. Use antistatic hose.
To periodically check and test the reliability of the grounding system, the grounding resistance is required to be less than 100 ohms.
Keep good exhaust and ventilation, away from flammable, explosive and heat sources.

How AODD PUMP works

The working principle of AODD PUMP:
Air diaphragm pump is a special form of positive displacement pump. It relies on the back and forth agitation of a diaphragm to change the volume of the working chamber to suck and discharge liquid.
The pneumatic diaphragm pump is mainly composed of two parts: the transmission part and the diaphragm cylinder head. The transmission part is a driving mechanism that drives the diaphragm to agitate back and forth. Its transmission forms include mechanical transmission, hydraulic transmission and pneumatic transmission, among which hydraulic transmission is widely used. The working part of the diaphragm pump is mainly composed of the crank connecting rod mechanism, the plunger, the hydraulic cylinder, the diaphragm, the pump body, the suction valve and the discharge valve, etc., among which, the driving mechanism and the reciprocating column composed of the crankshaft connecting rod, the plunger and the hydraulic cylinder The plug pump is 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 from the working fluid by a diaphragm. 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 transported 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, and does not touch the plunger and the sealing device, which makes the column Important parts such as plugs work completely in oil medium and are in good working condition.
The diaphragm must have good flexibility and good corrosion resistance, 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.

Product features of AODD PUMP plastic diaphragm pump:

Since air is used as power, the flow rate is automatically adjusted with the change of back pressure (outlet resistance), which is suitable for medium and high viscosity fluids. The working point of the centrifugal pump is set based on water. If it is used for a fluid with a higher viscosity, a reducer or frequency converter is required, which greatly increases the cost. The same is true for gear pumps.
It is reliable and low-cost to use pneumatic pumps in flammable and explosive environments, such as the transportation of fuel, gunpowder, and explosives, because: first, it is impossible to generate sparks after grounding; second, there is no heat generation during work, and the machine does not It will overheat; third, the fluid will not overheat because the diaphragm pump has the least agitation to the fluid.
In places with harsh construction sites, such as wastewater discharge from construction sites and industrial mines, due to the large amount of impurities and complex components in the sewage, the pipeline is easy to be blocked, which will cause excessive load on the electric pump, and the electric motor will be easily damaged due to heat. The pneumatic diaphragm pump can pass particles and has an adjustable flow rate. When the pipeline is blocked, it will automatically stop until it is unobstructed.
In addition, the diaphragm pump is small in size and easy to move, does not require foundation, occupies a very small ground, and is easy and economical to install. It can be used as a mobile material conveying pump.
In the treatment of hazardous and corrosive materials, the diaphragm pump can completely isolate the materials from the outside world.
Or ensure that no impurities contaminate the raw materials in some tests.
It can be used to transport fluids with relatively unstable chemical properties, such as photosensitive materials, flocculants, etc. This is because the shear force of the diaphragm pump is low and the physical impact on the material is small.

Advantages of pp aodd Pump as a new type of conveying machinery

Why is the new type of conveying mechanical pp aodd pump taken seriously

Air Operated Double Diaphragm Pump is a new type of conveying machinery, which is a novel type of pump in China. Using compressed air as the power source, all kinds of corrosive liquids, liquids with particles, high-viscosity, volatile, flammable, and highly toxic liquids can be exhausted.

The pneumatic diaphragm pump has four materials: plastic, aluminum alloy, cast iron, and stainless steel. Diaphragm pumps use nitrile butadiene rubber, neoprene, fluororubber, polytetrafluoroethylene, and polytetrahexaethylene according to different liquid media. To meet the needs of different users. It is installed in various special occasions and used to pump the medium that cannot be pumped by conventional pumps, and has achieved satisfactory results.

Pneumatic diaphragm pumps are suitable for occasions. Due to the above characteristics of pneumatic diaphragm pumps, diaphragm pumps in the world have gradually invaded the market of other pumps and occupied a part of them. For example, diaphragm pumps in the painting and ceramic industries have an absolute dominant position, while in some other industries, such as environmental protection, wastewater treatment, construction, sewage, and fine chemicals, it is expanding its market share, and other pumps are irreplaceable.
