How to see the selection parameters of the diaphragm air pump

How do you look at the selection parameters of diaphragm air pumps? Any pump equipment selection needs to be selected based on the performance parameters of the model. Diaphragm pumps are no exception. They are also based on the flow, head, suction, working pressure, etc. required by the transportation project. Parameters can be selected according to actual needs. For details, please refer to the following content brought by SAIKEN Pump Industry.

At present, the diaphragm pump model and specifications are relatively abundant. When selecting the model, the user mainly focuses on the parameters such as flow, pressure, and suction. At the same time, according to the different working conditions and environment, decide which pump body material to choose. Currently, cast iron and aluminum are supported. The pump body is made of alloy, stainless steel, plastic, rubber lining and other materials. In addition, depending on the composition of the transportation medium, it is necessary to consider which material the diaphragm is used. Zhongcheng Pump provides diaphragms made of nitrile rubber, neoprene, fluorine rubber, polytetrafluoroethylene, food rubber and other materials.

In fact, users don’t have to worry about how to look at the selection parameters of the diaphragm air pump at all. They only need to inform SAIKEN pumps of their transportation needs to get professional and detailed selection guidance. SAIKEN can provide complete and mature after-sales technical services. , So that users have no worries.

After the above introduction, you must also have a certain understanding of how to look at the selection parameters of diaphragm air pumps. If you want to know other pump information, you can refer to other related content in the station.

AODD PUMP features

AODD PUMP features:

Compressed air is the power.
It is a positive displacement pump whose volume changes caused by the reciprocating deformation of the diaphragm. Its working principle is similar to that of a plunger pump. Due to the characteristics of the working principle of the diaphragm pump, the diaphragm pump has the following characteristics:
(1) The pump will not overheat: compressed air is used for power, and it is a process of expansion and heat absorption when exhausting. The temperature of the pneumatic pump is reduced when it is working, and no harmful gas is discharged.
(2) No electric sparks: The pneumatic diaphragm pump does not use electricity as power, and prevents static sparks after being grounded
(3) Liquids containing particles can be passed: because the volumetric work and the inlet is a ball valve, it is not easy to be blocked.
(4) The shearing force to the material is extremely low: how to suck in and out when working, so the agitation to the material is minimal, suitable for the transportation of unstable materials
(5) The flow can be adjusted, and a throttle valve can be installed at the material outlet to adjust the flow.

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.

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.

Briefly introduce the AODD PUMP

The air-operated double diaphragm pump is also known as the control pump. It is the main type of actuator. By receiving the control signal output by the adjustment control unit, it uses power operation to change the fluid flow. The role of the AODD PUMP in the control process is to accept the control signal of the regulator or computer, change the flow of the adjusted medium, and maintain the adjusted parameters within the required range, so as to achieve the automation of the production process. If the automatic adjustment system is compared with the manual adjustment process, the detection unit is the human eye and the adjustment control unit is the human brain, then the executive unit—the diaphragm pump is the human hand and foot. To realize the adjustment and control of a certain parameter such as temperature, pressure, flow, and liquid level in the process, it is inseparable from the diaphragm pump.
There are five commonly used materials for pneumatic diaphragm pumps: plastic, aluminum alloy, cast iron, stainless steel, and Teflon. There are four kinds of materials for electric diaphragm pumps: plastic, aluminum alloy, cast iron, and stainless steel. According to different liquid media, the diaphragm of the diaphragm pump adopts nitrile rubber, neoprene rubber, fluorine rubber, polytetrafluoroethylene, polyhexaethylene, etc., to be placed in various special occasions to pump various media to meet the needs.
