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.

The application industry of AODD pumps is quite wide. The common ones are petrochemical and pharmaceutical machinery industries. The reason why diaphragm pumps are popular is that this pump product has unique characteristics and excellent comprehensive performance, which can replace a variety of common transportation equipment, such as It can be used as submersible pumps, self-priming pumps, mud pumps, canned pumps and other equipment in many situations.
Before understanding the application industry of the diaphragm air pump, it is necessary to have an understanding of its working characteristics and advantages. The diaphragm pump is a pneumatic pump. Unlike other motor pumps, which rely on power, it uses compressed air to achieve material discharge. Therefore, the motor is light and the whole pump is light, the internal structure is also very simple and compact, and the body is small, which brings great convenience to the use and installation. Moreover, according to actual working conditions, the pump body supports materials such as cast iron, stainless steel, aluminum alloy, and engineering plastics.
In terms of working performance, the adaptability of the diaphragm pump to the medium is comparable to that of a screw pump. At the same time, it can be self-primed, submersible, and can handle fluids with particles. It will not leak during transportation, and it will not heat up even if it is idling due to an accident. , It will not damage the pump even if it is running under load. It has an automatic protection function and has fewer internal components. It will not cause performance degradation due to component wear after long-term use like other pump products. It is an ideal transportation equipment at the moment.
Such a comprehensive performance, worry-saving and labor-saving transportation equipment is very popular in the current industrial field. The application industry of diaphragm air pumps is also increasing. It can be used to transport sewage in sewage ponds or other tunnels, and can suck more viscosity. High liquids, such as adhesives and glues, can also be used to transport hazardous media, such as various highly toxic, flammable, and volatile liquids. The pump’s tolerance to the medium is as high as 150°C, and it can handle transportation projects that many pumps cannot complete.
After the above introduction, I believe that you also have an intuitive understanding of the application industry of diaphragm air pumps. In short, the scope of application of this equipment is extremely wide, and because the motor is not used, it means that the use environment is not restricted. The remote corners of the power cord can be used freely. AODD pump manufacturers and suppliers
Knowing the disassembly steps of the Air Operated Diaphragm Pumps can effectively sort out the faults and facilitate the maintenance of the stable progress of the transportation project. This is also the basic mechanical knowledge necessary for equipment operators. SAIKEN Pumps combines the previous dismantling experience of pneumatic diaphragm pumps and organizes the relevant operating steps for reference. For details, please refer to the following.
AODD pumps are well-known for their excellent comprehensive performance and wide versatility. They are stable and reliable in daily operation, and the failure rate is not high. However, long-term use and harsh working conditions will inevitably bring wear and tear, so it is necessary to know the pneumatic Perform necessary maintenance on the diaphragm pump after the disassembly steps, the relevant steps are as follows.
Mark the pump body and air chambers on the left and right sides of the pneumatic diaphragm pump before disassembling to avoid subsequent assembly errors;
Remove the fastening bolt connecting the outlet pipe and the pump body. After disassembly, you can directly see the two key components of the valve ball and the valve seat. You can check the signs of aging and wear to determine whether you need to replace new parts; Abnormal, it will cause abnormal pressure of the pump, irregular work, etc.;
Separate the intermediates of the outer pump body and the inner pump body. After disassembling the pump body, the status of the diaphragm can be checked. The integrity of the diaphragm is particularly important. If it is damaged, the medium will leak;
To check the diaphragm, you need to use tools to fix the edge of the diaphragm outer splint, separate the diaphragm device from the intermediate body, and then rotate clockwise to loosen the diaphragm device;
After removing the outer splint of the diaphragm, take out the shaft in the intermediate body, and use a tool to separate the shaft and the diaphragm device to check the wear of the splint and diaphragm of the shaft;
Use a wrench or other tools to open the valve to check the wear of the piston, oil seal, sealing ring, resistance rod and other components;
Understanding the structure and principle of the ISG vertical pipeline pump can further strengthen the understanding and understanding of the sewage pump, which plays an important role in the daily maintenance of sewage equipment and the maintenance of stable transportation conditions. In this regard, SAIKEN Pumps has made a combing and introduction on related issues, hoping to help you have a more comprehensive and detailed understanding of this.
Regarding the structure and principle of the vertical sewage pump, the vertical ISG pump is mainly composed of motor, bearing, motor seat, mechanical seal, impeller, pump body, seal ring, base and other structural components. Among them, the impeller mainly uses a single-channel or double-channel form, with a scientific and reasonable volute chamber, which has a good flow effect, and can always maintain a vibration-free bass operation during operation. At present, the vertical sewage pump has two structural forms: the motor and the pump are coaxial, and the coupling is used to change the connection. Each structural form has two base connection forms.
In terms of working principle, the working principle of vertical sewage pump and centrifugal pump is different from that of physics, and the same is to use centrifugal force to throw sewage out. Before the sewage pump is activated, both the pump body and the water inlet pipe need to be filled with the liquid medium to be transported. After the vacuum state is formed, the impeller rotates quickly, and the liquid rotates rapidly with the blades, so that the liquid quickly moves from the impeller under the action of centrifugal force. At the same time, the central part of the impeller constitutes a vacuum area, and the liquid is squeezed into the water inlet pipe under the action of water pressure, and the cycle is repeated to realize the rapid discharge of the liquid.
After knowing the structure and principle of the vertical sewage pump, equipment users need to pay attention to that although the vertical sewage pump has many advantages, its performance is very reliable, and it can be directly submerged, but it should be paid more attention to when using it. Improper operation, especially do not idling, be sure to fill the medium before starting to avoid idling causing cavitation. Vertical pipeline pump manufacturers and suppliers
Can the ISG pipeline pump pass water when it is not energized? In normal operation, the pipeline pump uses the centrifugal force generated by the rotation of the impeller to throw the water out. The pipeline pump does not operate when the power is not turned on. If the water wants to flow through, it will encounter greater resistance. If you want to flow through the water when it is stopped, Unless there is enough pressure, the flow rate will be greatly reduced even if the water can pass.
Regarding the question of whether the pipeline pump can pass water when it is not energized, simply speaking, when the pipeline pump is not working, the internal impeller does not rotate, which will produce high resistance to the passage of liquid and cannot effectively transport the liquid. Even if the pressure is sufficient, the discharge amount of liquid will be lower than the discharge efficiency during normal operation. It is also worth noting that if there is fluid in the pump cavity without power for a long time, it will cause wear and tear on the pipeline pump. If the environment is harsh, it may cause scale and rust in the pump cavity. It is recommended to lower the pump when it is not used for a long time. Keep the effusion after draining.
After understanding whether the pipeline pump can pass water when it is not energized, the equipment operator should avoid long-term power failure and excessive water use, so as not to damage the performance and service life of the equipment. You can refer to the following maintenance suggestions for pipeline pumps.
Before starting the pipeline pump, it is necessary to inject enough liquid into the inlet pipeline, and it cannot run for a long time under the cavitation state;
Pipeline pumps will inevitably have mechanical wear after long-term use. Generally, it is recommended to check the pump once a year and replace the old or damaged parts that are not applicable in time;
Maintain the maintenance of the mechanical seal, ensure that the seal is lubricated and clean, and strictly prohibit the mechanical seal from working under dry grinding conditions;
The mechanical seal of the pipeline pump has a leakage of about three drops per minute during operation. If it exceeds, it needs to be inspected.
To sum up, it is a related introduction to whether the pipeline pump can pass water when it is not energized. It also helps you understand the related maintenance methods. It is recommended to use the pipeline pump correctly to reduce improper operation and avoid premature loss of performance of the pipeline pump. . If you are interested in knowing more pump information, continue to pay attention to the SAIKEN pump industry.
