Overview of pneumatic diaphragm pump
Pneumatic diaphragm pumps are mainly used for mine roadway development, shaft shaft construction, mining working face troughs and various Sewage discharge around equipment, drainage, sewage sand discharge, mud discharge in underground cavern 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.
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.
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.

Starting and stopping load operation
The diaphragm pump is driven by a variable frequency motor. If the starting and stopping load is too large or too small, Large short-term load fluctuations, long-term operation at low load, etc. all have an impact on the inverter. In order to avoid the above situations as much as possible, it is rigidly stipulated that the starting and stopping loads are controlled at around %, and settings are made in the instrument so that the load increases and decreases. It must be completed within a period of time, effectively achieving the maintenance of the frequency converter from a technical perspective.
Pressure system operation
The instrument air and lubricating oil pressure of the diaphragm pump are interlocked with the main motor. The oil filling and oil drain valves of the propelling fluid are air-closed valves, and a certain air pressure must be maintained at all times. The minimum operating pressure of the two valves is not less than . , so the instrument air pressure is generally maintained above . Even after the pump is stopped, the instrument air is not stopped to avoid insufficient or excessive liquid in the liquid chamber. The air supplied to the valve is filtered, Oil atomized.
When the diaphragm pump is running, the lubricating oil pressure should not be lower than the pressure interlock value (), and the pressure difference of the lubricating oil outlet filter should not be too large. The steel ball in the lubricating oil flow sight glass should be at the upper limit position. When adjusting this flow rate, the adjustment range should not be too large to avoid excessive instantaneous flow and rapid pressure drop causing interlocking tripping.
Through the above process improvements and proficiency in operating key points, the diaphragm pump always has a stable process environment during operation. In more than a year of operation, there was only one trip due to electrical reasons, achieving long-term and safe operation. Run efficiently.
