Overview of pneumatic diaphragm pump
Pneumatic diaphragm pump is mainly used It is used in mine roadway development, shaft shaft construction, sewage discharge around mining working face troughs and various equipment, drainage, sewage sand discharge, mud discharge in underground cave chamber projects, mine roadway spray whitening applications, 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.
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.

Troubleshooting
Editor
Diaphragm pump troubleshooting guide When encountering one or more of the following situations, this information can be used as a guide, Help you develop repair measures.
As shown below, there are several abnormal operating conditions described in this guide) Fast circulation/low flow) No circulation/slow circulation/irregular circulation) Leakage) Noise) Component breakage
In the pump During the application process, these situations may be encountered. Each situation can be divided into several possible causes. This guide lists the causes of malfunctions and provides corresponding correct repair measures. The meanings of all specific terms in the guide are listed below.
The copper or stainless steel valve housing of the air valve is fixed on the center body of the pump by four bolts.
The piston aluminum cylinder is enclosed in the air valve and controls the air flow.
Cavitation Due to the reduction or lack of fluid supply at the pump inlet, the pump discharge volume is lower than the rated volume. In fact, the liquid chamber is filled with fluid before discharge.
The vertical distance (in feet) between the static pressure relief head from the center line of the pump to the free delivery point. Inlet pressure The inlet is measured in pounds and includes the specific gravity and flow rate of the fluid.
Specific gravity is the ratio of flow rate to water weight. The specific gravity of water is
The vertical distance from the static suction lift supply liquid level to the center line of the pump. The pump should be above the liquid level.
Vapor Pressure The vapor in all liquids produces pressure on its free surface. In any pump operating system, the operating pressure cannot be lower than the vapor pressure, otherwise the vapor formed will partially or completely cut off the flow to the pump. Viscosity Due to the existence of internal friction in the fluid, the property of viscosity causes the fluid to generate flow resistance.
Water hammer effect
Water hammer occurs when there is a sudden power outage or when the valve is closed too quickly. Due to the inertia of the pressure water flow, a water flow shock wave is generated, just like a hammer striking, so it is called water hammer. The force generated by the back and forth shock waves of water flow can sometimes be so great that it can damage valves and water pumps. The water hammer effect means that inside the water pipe, the inner wall of the pipe is smooth and the water flows freely. When the open valve is suddenly closed, the water flow will generate a pressure on the valve and pipe wall, mainly the valve. Because the pipe wall is smooth, the subsequent water flow quickly reaches the maximum under the action of inertia and produces destructive effects. This is the water hammer effect in hydraulics, that is, positive water hammer. This factor must be considered in the construction of water conservancy pipelines. On the contrary, when a closed valve is suddenly opened, it will also produce water hammer, which is called negative water hammer. It also has a certain destructive power, but it is not as big as the former. .
