Overview of the pneumatic diaphragm pump
Pneumatic diaphragm pumps are mainly used for mine roadway development, shaft shaft construction, sewage discharge around mining working face tanks and various equipment, drainage, sewage discharge, sand discharge, mud discharge in underground cave chamber projects, and mine tunnel whitening applications. wait. 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.
Working principle of pneumatic diaphragm pump
Mining pneumatic 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.

Jining Dongda Mechanical and Electrical Co., Ltd. now has ten series and more than 40 varieties of products. The main products are pneumatic diaphragm pumps and mining diaphragm pumps
Notes on use
Pneumatic diaphragm pumps are powered by compressed air and cause volume changes through reciprocating deformation of the diaphragm. Its working principle is similar to that of a plunger pump. .
Pay attention to the following points when operating a pneumatic diaphragm pump
Ensure that the largest particles contained in the fluid do not exceed the maximum safe passing particle diameter standard of the pump.
. The inlet pressure should not exceed the maximum allowable operating 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 pipeline system can withstand the highest output pressure achieved and ensure the cleanliness and normal working conditions of the drive air system.
Static sparks may cause explosions, resulting in personal casualties and property losses. Use wires with a large enough cross-sectional area as needed to properly and reliably ground the grounding screw on the pump.
The grounding requirements comply with local regulations, legal requirements and some special requirements on site.
Tighten the pump and the connecting pipe joints to prevent static sparks caused by vibration, impact and friction. Use antistatic hose.
It is necessary to periodically check and test the reliability of the grounding system, and the grounding resistance is required to be less than ohms.
, maintain good exhaust and ventilation, and stay away from flammable, explosive and heat sources.
Application Advantages
Editor
The 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 . Diaphragm pumps are available in four materials: plastic, aluminum alloy, cast iron, and stainless steel.
The diaphragm pump uses nitrile rubber, chloroprene rubber, fluorine rubber, polytetrafluoroethylene, and polytetrafluoroethylene according to different liquid media. To meet the needs of different users. It is placed in various special occasions and used to pump various media that conventional pumps cannot pump, and has achieved satisfactory results.
In the spray painting and ceramics industries, diaphragm pumps have occupied an absolute dominant position. The advantage of pneumatic diaphragm pumps is that
Since air is used as power, the flow rate automatically adjusts with changes in back pressure (outlet resistance). , suitable for medium to high viscosity fluids. The working point of the centrifugal pump is set based on water. If it is used for fluids with slightly higher viscosity, it will need to be equipped with a reducer or frequency converter, which will greatly increase the cost. The same is true for gear pumps.
Pneumatic pumps are reliable and low-cost 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 generated during operation, and the machine No overheating Third, the fluid will not overheat because the diaphragm pump causes minimal agitation of the fluid.
In places with harsh construction sites, such as construction sites, industrial and mining wastewater discharge, due to the large number of impurities and complex composition in the sewage, the pipes are prone to blockage, which causes an overload on the electric pump and the motor is prone to heat. damage. The pneumatic diaphragm pump can pass particles and the flow rate is adjustable. When the pipeline is blocked, it will automatically stop until it becomes unobstructed.
, can be used to transport fluids with relatively unstable chemical properties, such as photosensitive materials, flocculation liquid, etc. This is because diaphragm pumps have low shear forces and have little physical impact on materials.
In the processing of hazardous and corrosive materials, the diaphragm pump can completely isolate the materials from the outside world.
, or some tests to ensure that there are no impurities contaminating the raw materials.
In addition, the diaphragm pump is small and easy to move, does not require a foundation, occupies a very small area, and is easy and economical to install. Can be used as a mobile material transfer pump.
