BQG100/0.4 pneumatic diaphragm pump specifications and dimensions-produced by pneumatic diaphragm pump manufacturers

Specifications and dimensions of pneumatic diaphragm pumps. Produced by pneumatic diaphragm pump manufacturers
. , shaft shaft construction, sewage discharge around mining working face troughs and various types of equipment, drainage, sewage sand discharge, mud discharge in underground cave chamber projects, whitewashing 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.
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
Common faults of diaphragm pumps Causes and treatment methods
, Causes and treatment methods of insufficient flow rate of diaphragm pump
, Inspection and repair of leakage in the feed and discharge valves or replacement of the feed valve
, Replacement of the diaphragm if the diaphragm is damaged
/>, the rotation speed is too slow, the adjustment fails, repair the control device, and adjust the rotation speed.
, Diaphragm pump pressure is insufficient or increased failure causes and treatment methods
, Pneumatic diaphragm pump pressure regulating valve is improperly adjusted to adjust the pressure valve to the required pressure
, Pressure regulating valve failure, maintenance and pressure adjustment wide
Maintenance of pressure gauge or replacement of pressure gauge.
, Causes and treatment methods of diaphragm pump pressure drop failure
, Insufficient oil supply in the oil supply valve, repair the oil valve
, Insufficient feed or leakage of the feed valve, repair the feed situation and feed valve
br/>. Oil leakage from the plunger seal. Repair the sealing part.
. The oil level in the oil storage tank is too low. Fill in new oil.
, Causes and treatment methods of diaphragm pump oil leakage failure
, Gaskets and sealing rings are damaged or too loose. Adjust or replace the gaskets and sealing rings.
