How to improve the self-priming ability of corrosion-resistant self-priming pumps-Saiken Pump Industry

When we bought a self-priming pump, one thing we valued is its self-priming ability. Seiken Pump will introduce how to improve the self-priming ability of the self-priming pump.

How to improve the self-priming ability of corrosion-resistant self-priming pump

Install a bottom valve at the entrance of the corrosion-resistant self-priming pump: the bottom valve is actually a check valve, which can make the water flow only from the pool into the suction pipe without backflow, so there will always be water in the pump body. The self-priming force will not be affected.
The corrosion-resistant self-priming pump reduces the bends, drop height and horizontal distance of the inlet pipe.
Install a vacuum pump on the suction pipe of the water pump. Before the water pump is started, the vacuum pump is started first, so that the water suction pipe of the water pump is filled with water first to ensure that the water pump starts automatically and quickly. This type of water absorption requires a complete automatic control system to ensure normal operation.
The gas-liquid separation acceleration device can be installed to accelerate the gas-liquid separation, that is, the self-priming time can be shortened. The simplest gas-liquid separation acceleration device is to add a baffle in the gas-liquid separation chamber.

AODD PUMP application advantages

AODD PUMP application advantages:
The aerodynamic double diaphragm pump is a new type of conveying machinery that can convey various corrosive liquids, liquids with particles, high viscosity, volatile, flammable, and highly toxic liquids. The diaphragm pump has four materials: plastic AODD PUMP, aluminum alloy AODD PUMP, cast iron AODD PUMP, stainless steel AODD PUMP.
Diaphragm pumps use nitrile rubber, chloroprene rubber, fluorine rubber, 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.
Diaphragm pumps have an absolute dominant position in the painting and ceramic industries. The advantages of pneumatic diaphragm pumps are:

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.
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.
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 raw materials in some tests.
In addition, the diaphragm pump is small in size, easy to move, does not require a foundation, occupies a very small area, and is easy and economic to install. It can be used as a mobile material transfer pump.

Today we will talk about AODD PUMP

Today we will talk about AODD PUMP:
The installation method of the diaphragm in the Air operated double diaphragm pump, which does not affect the volume change requirements of the pump, and makes full use of the excellent pressure resistance of the diaphragm. It is carried out on the geometrical size of the diaphragm. It does not need to increase the cost and workload, and it does not need to increase the cost and workload. It can greatly improve the service life of the diaphragm, ensure the normalization of production and improve the quality of product production. It can be applied to the installation of diaphragms in various diaphragm pumps.
The diaphragm pump equipment system consists of one or more double-sided pumps, such as a pneumatic double diaphragm pump. The manifold on the pump is separated, so that each side of the pump pumps one component of the multi-component material, and an accumulator is connected to the outputs on both sides, so that the out-of-phase output of the pump becomes the same phase. Diaphragm isolation valves can be used on each side of the pump to prevent the mixed material from flowing back. If a mixing ratio other than 1:1 is required, more than one such pump can be used together to achieve a variety of mixing ratios.
The diaphragm failure monitoring system is used to detect the leakage of the diaphragm of the diaphragm pump. The system includes a pump that has a working chamber with working fluid inside; a pumping chamber for pumping materials into and out of the pump; and a diaphragm to isolate the working chamber from the pumping chamber. A first optical fiber is connected with the working chamber to transmit an optical signal through the working fluid. A second optical fiber is connected to the working chamber to receive the optical signal transmitted by the first optical fiber. An electrical signal establishment device that establishes the first electrical signal when the optical signal is transmitted from the first optical fiber, passes through the uncontaminated working fluid and reaches the second optical fiber. This electrical signal establishing device establishes a second electrical signal when the optical signal is transmitted from the first optical fiber, passes through the contaminated working fluid and reaches the second optical fiber. When the second electrical signal is established, according to this, the leakage of contaminated material through the diaphragm into the working chamber can be detected.

Let’s take a look at AODD PUMP

Let’s take a look at AODD PUMP：
A diaphragm is installed in each of the two symmetrical working chambers of AODD PUMP, which are connected by a central link. Compressed air enters the valve from the air inlet of the AODD PUMP, and the compressed air is introduced into one of the chambers through the air distribution mechanism to push the diaphragm in the chamber to move, while the gas in the other chamber 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, compressed air enters the valve to move the diaphragm 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.

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.
