Overview of pneumatic diaphragm pumps
Pneumatic diaphragm pumps are mainly used for mine roadway development, shaft shaft construction, and mining working face troughs. And sewage discharge around various types of equipment, drainage, sewage sand discharge, mud discharge in underground cave chamber projects, white spray applications in mine tunnels, etc. The pneumatic diaphragm pump produced by our company adopts, absorbs and improves the most advanced pneumatic diaphragm pump production process and technology in the world. This product is specially designed for coal mines and has traditional submersible electric pumps, mud pumps, impurity pumps and flexible shaft pumps. All functions are a revolution in traditional mining water pumps. The key is to completely solve the safety issues of traditional water pumps. The product can provide high conveying speeds at low air pressures and is compatible with a wide range of materials. This water pump has an anti-stall design and a modular pneumatic motor/fluid part.
Pneumatic diaphragm pumps are used to discharge clean water underground in coal mines, or sewage containing solid particle impurities (volume concentration less than %). They can also be used in non-coal mines and other occasions with similar transmission media.
Structure of pneumatic diaphragm pump
Pneumatic diaphragm pump is composed of water outlet manifold, pump cover, pump body, water inlet manifold, diaphragm, ball, working principle of ball pneumatic diaphragm pump
Mining pneumatic The diaphragm pump uses the pressure difference in the air chamber to alternately generate suction liquid pressure and positive liquid pressure in the liquid chamber. Controlling the valve switch can ensure the forward flow of liquid. After ventilation, the pump starts running and works continuously to ensure that the required pressure remains constant. The pump will increase and maintain the delivery pipe pressure, and when the maximum delivery pipe pressure is reached (or the distribution valve is closed), it will stop working and when needed time, resume pumping.
Technical features of pneumatic diaphragm pump
The pneumatic diaphragm pump for mining uses air flow to push the valve core to reciprocate, so that the pressure air enters the left and right air chambers alternately, causing it to push the diaphragm to reciprocate and make the working chamber A pressure difference is generated inside to achieve the purpose of water absorption and drainage. It is small in size, light in weight, and does not require a foundation. It can be used as a mobile pump without lubrication. The main valve has no special requirements for the air source and can be started by self-priming.
Selection of caliber
) Determination of calculated flow rate. The existing production capacity, equipment load and medium conditions determine the calculation of flow rate and
) the determination of the pressure difference before and after the valve. Based on the selected valve flow characteristics and system characteristics (resistance coefficient), determine the calculated pressure difference.
) calculation. Select appropriate calculation formulas and charts according to the medium being adjusted, and obtain and
) for selection. Based on the selected product standard series and the closest one to it, the opening of the diaphragm pump is calculated. Generally, it is required that the opening degree is ≯% when the maximum flow rate is calculated, and the opening degree is ≮% when the minimum flow rate is calculated.
) Calculation of the actual adjustable ratio of the diaphragm pump. It is generally required that the actual adjustable ratio ≮.
) Determination of valve seat diameter and nominal diameter. After verifying that it is suitable, press OK.
Conclusion
The selection of diaphragm pump is a very detailed work, which requires not only solid professional theoretical knowledge, but also rich practical experience. Good selection not only helps to adjust the parameters of the control loop, so that the adjusted parameters can be better controlled, but also greatly increases the service life of the diaphragm pump. The selection of diaphragm pumps must be adapted to local conditions and is not static. It must be constantly summarized and innovated in the process of practice. Especially with the application of mechatronics technology, computers and digital information technology, the structure and function of diaphragm pumps have become better and more comprehensive. It provides great convenience for selecting diaphragm pumps.
