Shandong BQG320/0.3 pneumatic diaphragm pump first Dongda Electromechanical

Shandong pneumatic diaphragm pump is the first Dongda Electromechanical... And technology, this product is specially designed for coal mines. It has all the functions of traditional submersible electric pumps, mud pumps, impurity pumps and flexible shaft pumps. It is 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.
2. Main Features
The pneumatic diaphragm pump uses air flow to push the valve core to reciprocate, causing the pressure air to enter the left and right air chambers alternately, causing it to push the diaphragm to reciprocate and generate pressure in the working chamber. Poor, 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.
3. Working Principle
The 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 the 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.

Hidden danger troubleshooting
1. The pump is running but the flow rate is too low
Check the pump body for cavitation and adjust the compressed air inlet pressure. Reduce the operating speed of the pump to adjust liquids with higher viscosity and concentration.
Check whether the valve ball is stuck. If the liquid being transported does not match the material of the valve ball. The valve ball will expand. Please replace the valve ball and valve seat with suitable materials.
Please check whether the inlet pipe is blocked.
2. The pneumatic pneumatic diaphragm pump cannot start or moves slowly
Check whether the filtering, pressure regulating and lubrication devices and the air inlet filter are blocked.
. Check whether the air valve is stuck by impurities. Please remove the air valve and clean it, and check whether the piston in the air valve has any scratches. If the piston surface is bright but not black, it means the piston and ring are worn and need to be replaced. Traces of injury. Please replace it with a new one
. Check the spindle and the ring for signs of scratches, wear and flattening. If damaged, please replace it.
3. Liquid leaks from the discharge port of the air chamber
Please check whether the diaphragm is broken.
Check whether the diaphragm is installed and locked correctly.
4. The outlet liquid contains a large number of bubbles
Please check whether the diaphragm is broken.
Check the pump body and pipeline for leaks.
Regular maintenance
After the pump has been running for a long time, it will be unable to absorb water. At this time, certain maintenance is required for the pump that has been running for a long time, especially for the highly corrosive wastewater residues in industrial wastewater. .
Prepare a maintenance kit. Usually air pump manufacturers provide maintenance kits, the main ones commonly used are seals and silencers.
. According to actual usage conditions, regularly maintain the air pump and clean up some leftover waste residue to ensure sealing.
. Each pneumatic pump suction inlet has a filter and is cleaned regularly.
