Pneumatic diaphragm pump overview
Pneumatic diaphragm pump is mainly used for mine roadway development, shaft shaft construction, mining working face trough and other types Sewage discharge around equipment, drainage, sewage discharge, sand discharge, mud discharge in underground tunnel projects, white spray application 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, ball seat, outlet pipe, slide valve, muffler, piston, Composed of air inlet pipe, water inlet section, etc.
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, and controls the valve switch to Ensure positive 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.
Common types
Editor
The pneumatic diaphragm pump is a new type of conveying machinery that uses compressed air as the power source and uses the diaphragm in the cylinder to agitate back and forth to achieve the purpose of conveying various media.
Media that can be transported Pneumatic diaphragm pumps are suitable for transporting various corrosive and particle-laden liquids, as well as high-temperature, volatile, flammable and highly toxic liquids.
Material selection
The materials used for the shell include aluminum alloy, cast iron, and stainless steel.
The materials used for the diaphragm include nitrile rubber, chloroprene rubber, fluorine rubber, and polytetrafluoroethylene.
The working principle of the pneumatic diaphragm pump
In each of the two symmetrical working chambers of the pump, an elastic diaphragm is installed. The connecting rod connects the two diaphragms into one body. The compressed air comes from the air inlet of the pump. After the joint enters the gas distribution valve, it pushes the diaphragms in the two working chambers to move, driving the two diaphragms connected by the connecting rod to move synchronously. At the same time, the gas in the other working chamber is discharged from the back of the diaphragm out of the pump. Once it reaches the end of the stroke, the gas distribution mechanism automatically introduces the compressed air into the other working chamber and pushes the diaphragm to move in the opposite direction. This forms a synchronous reciprocating motion of the two diaphragms. Each working chamber is equipped with two one-way ball valves. The reciprocating motion of the diaphragm causes a change in the volume of the working chamber, forcing the two one-way ball valves to open and close alternately, thereby continuously sucking and discharging liquid.
Purpose
It can pump all kinds of sewage.
, can suck various chemical corrosives, oil, mud, and clean grease.
, can pump various highly toxic, flammable and volatile liquids.
, can pump various strong acid, strong alkali and strong corrosive liquids.
, can pump various high-temperature liquids, and the maximum temperature can withstand ℃.
, can be used as the front-end pressure supply equipment for various solid-liquid separation equipment.
Characteristics of pneumatic diaphragm pump
No need to fill or divert water, high suction lift, high lift, outlet pressure)/.
, good flow performance, allowing the maximum particle diameter to pass through. When pumping mud and impurities, there is little wear on the pump.
The lift and flow rate can be adjusted steplessly through the opening of the air valve (the air pressure can be adjusted between one and two).
This pump has no rotating parts and no shaft seal. Relying on the reciprocating motion of a pair of diaphragms, various media are pumped. Since the moving parts of the pump are completely separated from the working medium, the transported media will not leak outward, avoiding environmental pollution and personal hazards.
, does not use power supply, can be used in flammable and explosive places, safe and reliable.
It can be immersed in the medium to pump liquid instead of a submersible pump.
When starting and stopping the pump, you only need to open and close the gas valve to operate. Even if there is no medium pumping for a long time or a sudden shutdown due to unexpected circumstances, the pump will not be damaged. Once overloaded, the pump will automatically shut down and have self-protection capabilities. When the load returns to normal, it can start running automatically again.
, simple structure and few wearing parts. The diaphragm pump has a simple structure and is easy to install and maintain. When the pump transports media, it will not come into contact with moving parts such as valves and connecting rods, which avoids corrosion and wear of the parts.
, can transport relatively loose liquids.
, No oil lubrication is used, even if it is idling, it will not have any impact on the pump. []
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. A pressure difference is generated in the working chamber 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.
