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.

Pneumatic diaphragm pump and screw pump

The difference between pneumatic diaphragm pump and screw pump:
Air Operated Diaphragm Pump is a kind of conveying mechanical equipment that is very commonly used now, and it is recognized and trusted by the industry. People often confuse pneumatic diaphragm pumps with screw pumps, so what are the differences between pneumatic diaphragm pumps and screw pumps, and how to choose them. People will confuse the two because they have the same characteristics, but in fact the two are also very different. The pneumatic diaphragm pump is powered by compressed air to complete the work. There is no need to use electricity in this process, and it also reduces accidents caused by electric shock. Therefore, the safety of the pneumatic diaphragm pump will be better, it can be effectively explosion-proof and anti-static, and its anti-corrosion performance is also good, and it can resist the corrosion of chemical substances to a certain extent. The working principle of a screw pump is similar to that of a gear pump, but the screw replaces the gear in structure, but the working power it needs is electricity. It is precisely because the motor is needed to complete the work, so in the process of work, a certain amount of heat will be generated due to friction. The flow rate of the pneumatic diaphragm pump can be adjusted. The adjustment place is at the material outlet, and a throttle valve is installed to adjust the flow rate. The flow rate of the screw pump is relatively stable, so its vibration will be relatively small and the noise will be relatively low. In addition, the operation process of the pneumatic diaphragm pump is relatively simple, it does not have a complicated control system, and there are no materials such as cables and fuses. But on the contrary, the operation of the pneumatic diaphragm pump will be more complicated, and the requirements from processing to assembly are very high. As for how to choose, it actually depends on the actual needs of the industry. It is important to choose according to your own actual needs and choose the one that suits the industry. The above is the introduction about the difference between pneumatic diaphragm pump and screw pump. Different two kinds of mechanical equipment will definitely have many differences, but their functions are the same. I believe that after people understand the difference, they will know how to choose the right equipment. The key point is to choose according to their actual situation, so that they can better meet their needs.
The material that the screw pump is suitable for is lighter than that of the pneumatic diaphragm pump and has a relatively low shear force.
1. Comparison between screw pump and diaphragm pump Screw pump has a strong ability to transport abrasive fluids. Pneumatic diaphragm pumps are another option, both of which have the advantage of less floor space. However, the diaphragm pump generates significant vibration and spreads through the pipeline, causing the pipeline and infrastructure to vibrate. Vibration damping devices are almost often installed together with diaphragm pumps. Their failure, jams, and inaccurate positioning will cause problems in the entire system. However, the screw pump is vibration-free, running smoothly and quietly. Second, the advantages of screw pump The size of the particles delivered by the screw pump is only affected by the flow area, and the flow area is easily determined according to the open end of the pump. For a given required flow rate, large pumps run at low speeds and can handle larger solids, with little wear due to low operating speeds. Many factors affect the wear rate. As an approximate empirical formula, the service life of the screw pump is set to the third power of the speed. A key part of the screw pump is the stator rubber bushing. Most rubbers cannot be used at high temperatures, so most screw pumps operate at temperatures below 180°F. The elastomer commonly used for screw pump bushings is rubber, such as nitrile rubber or natural EPDM. Tetrafluoroethylene has also been used, although it is used less frequently, it is generally used at temperatures close to 300°F.
The screw pump cannot transport corrosive chemicals. Like sulfuric acid, alkaline substances and similar substances, it is easy to use other types of pumps, such as pneumatic diaphragm pumps when the viscosity is relatively high.

In “direct drive” pumps, the impeller of the pump is attached to the shaft of the motor and this design depends on the Mechanical shaft seal.
In a magnetic drive pump, the wet end and motor are two separate parts, connected by a motor bracket. At the end of the motor shaft, a drive magnet is attached, and as the drive magnet rotates around the rear housing, the impeller, which is fixed upon another magnet, spins in synchronization. It is the attraction of the drive magnet and the impeller magnet which allows the full torque of the motor to be passed onto the pump. As the shaft of the motor does not extend into the pump there is no need for a shaft seal. Thus without a shaft seal, the danger of leakage commonly associated with a shaft seal is eliminated. Furthermore, the maintenance cost is reduced because no time or money is spent on maintaining the shaft seal.

Deep Well Pump Features

China saiken Pump Industry Deep Well Pump Features:
1. Large flow, full head, full voltage, suitable for agricultural and industrial use;
2. Oil-immersed motor, with a diving depth of 120 meters;
3. The use environment of the water pump, clean water at room temperature;
4. Engineering plastic impeller, suspension design;
5. The ceramic sand-resistant structure is wear-resistant.

The depth of the Stainless Steel deep well pump down to the static water surface generally does not exceed 70 meters.
(1) The inlet of the water pump must be below 1 meter at the dynamic water level, but the diving depth must not exceed the static water level by 70 meters, and the lower end of the motor must be at least 1 meter below the bottom of the well.
(2) The rated power is less than 15kw or equal to 15kw (25kw when the power supply is allowed).
If it is a submersible pump, the general submersible pump is marked with the maximum depth that can be put into the water, and it is enough not to exceed this data. If this data is not marked, the dive depth should be reduced as much as possible while ensuring water absorption. If it is a long shaft deep well pump, it is not subject to depth constraints, as long as the motor is not flooded.
The biggest feature of the deep well pump is the integration of the motor and the pump. It is a pump that is immersed in the groundwater well to pump and transport water. It is widely used in farmland irrigation and drainage, industrial and mining enterprises, urban water supply and drainage, and sewage treatment. Since the motor is submerged in the water together, the structure of the motor is more special than the general motor. The structure of the motor is divided into four types: dry, semi-dry, oil-filled, and wet

Installation steps of submersible deep well pump

The submersible deep well pump is a general-purpose water-lifting machine that directly connects the motor and the water pump to submerged into the water. Its working principle is that the motor drives the impeller to rotate at a high speed through the pump shaft, and works on the liquid under the action of centrifugal force to convert the mechanical energy into Liquid energy, the liquid (water) flies away from the impeller and shoots out. The speed of the injected liquid in the diffusion chamber of the pump casing gradually slows down and the pressure gradually increases, and then flows out from the discharge pipe of the pump outlet. But many people don’t know how to install it, let us all understand the installation steps together:

(1) Remove the water strainer located in the middle of the submersible deep well pump, unscrew the water filling screw plug and the water drain screw plug, fill the machine with clean neutral water, and then tighten the screw plug.

(2) Use a 500 volt megohmmeter to measure the edge resistance of the motor should not be less than 150 megohms, and use a screwdriver to pry the impeller should rotate freely without jamming.

(3) First connect the short water pipe of the submersible pump to the check valve body, install a pair of splints under the upper flange of the short water pipe, and then gently lift the pump and put it into the well so that the splint is seated On the manhole cover.

(4) Use another pair of splints to clamp the long water delivery pipe and hoist it to connect with the short water delivery pipe, then remove the first set of splints to hoist another long water delivery pipe, repeat the installation according to this, and then cover the manhole cover to fix the splint On the well cover, finally install the bent water pipe, valve, water outlet pipe, and deep well submersible pump.

(5) During the installation of the submersible deep well pump, the pipeline rubber pad should be put between the two flanges of the pipeline, the bolts should be tightened symmetrically, and the cable should be tied into the groove on the water pipe flange; The cable is used as a sling, and it is not allowed to damage the cable.

The above are the installation steps of the submersible deep well pump. Only by clearly remembering and mastering these steps can the machine play its best role.

Precautions for the use of magnetic pumps and pipeline installation requirements

Precautions for the use of magnetic pumps and pipeline installation requirements

Due to the design characteristics of the magnetic pump, maintenance is generally not required, but in order to ensure its normal operation and safe operation, process monitoring devices should be used and strict management.
First, the inlet tank liquid level protection control is necessary. The inlet tank should be equipped with a liquid level transmitter or a liquid level switch. When the liquid level in the inlet tank drops to a certain level, the operation of the pump is automatically stopped to protect the pump. A differential pressure sensor and switch should be installed to measure the differential pressure between the outlet and inlet of the pump, and automatically stop the pump when the differential pressure is lower than the set value to protect the pump.
Second, the pump body should be equipped with a temperature sensor to monitor the temperature of the magnetic stator and pump bearing, and protect the bearing and magnetic stator. In order to avoid cavitation, the magnetic pump needs a small suction head when transporting easily vaporized fluid. The vibration of the pump is extremely small, and large vibration and noise indicate a malfunction.

Third, the pump outlet should be equipped with a liquid level regulating valve to adjust the displacement of the conveying medium according to the liquid level of the inlet tank. In order to ensure normal operation, the pump should be ensured to work within the range of flow and head. Small and large working flow and head are indicated on the performance curve.
The inlet pipeline and outlet pipeline of the pump should be supported to prevent additional load from being transmitted to the pump. The pump cannot be used as a stress point in the pipeline. Ensure that the pipeline system has compensation measures for thermal expansion.
When the positive suction head is low, the inlet pipe should be as short as possible to prevent cavitation. The inlet pipeline should have an appropriate size to ensure that the fluid flow rate does not exceed 3m/s; when transporting easily vaporized fluid or liquefied gas, ensure that the flow rate does not exceed 3m/s; when transporting easily vaporized fluid or liquefied gas, ensure the flow rate Not more than 1m/s.
A regulating valve should be installed in the outlet pipeline to adjust the flow and lift of the pump. When using a longer outlet pipeline or using two pumps in parallel, it is recommended to install an additional one-way check valve. In order to realize the continuous operation of the pump, it is recommended to install a return line and install a small flow orifice to ensure sufficient lubrication and cooling of the sliding bearing during continuous operation.
The entire piping system and auxiliary piping should be carefully cleaned to prevent iron filings, welding slag or other foreign matter from entering the magnetic pump. For newly built piping systems, the inlet piping should be equipped with a filter.
