Affordable submersible pump BQG350/0.2 pneumatic diaphragm pump

Affordable submersible pump pneumatic diaphragm pump 1. Overview
The 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 All the functions of traditional submersible electric pumps, mud pumps, impurity pumps and flexible shaft pumps 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.
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.
The pneumatic diaphragm pump is a volumetric pump that uses compressed air as power and causes volume changes through reciprocating deformation of the diaphragm. Its working principle is similar to that of a plunger pump. Pneumatic diaphragm pumps are used according to certain principles and methods, and are used according to certain instructions and precautions in specific operating procedures. They can produce important functions and contributions and exert good use value. When operating a pneumatic diaphragm pump, pay attention to the following points to ensure that the largest particles contained in the fluid do not exceed the maximum safe particle diameter standard of the pump. Tighten the pump and all connecting pipe joints to prevent static sparks from the split pump due to vibration, impact and friction. Use antistatic hose. The reliability of the grounding system must be periodically checked and tested, and the grounding resistance must be less than ohms. Maintain good exhaust and ventilation, and keep away from flammable, explosive and heat sources. The inlet pressure should not exceed the maximum allowable operating pressure of the pump. Compressed air higher than the rated pressure of the pipeline pump may cause personal injury and property damage and damage the performance of the pump.
Static sparks may cause explosions, resulting in personal injury or death and property damage. Use wires with a large enough cross-sectional area as needed to properly and reliably ground the grounding screw on the pump. Grounding requirements comply with local regulations, legal requirements and some special requirements on site. The exhaust from the pump may contain solid matter. Do not point the exhaust port toward the work area or people to avoid personal injury. When the diaphragm fails, material transported by the sewage pump will be ejected from the exhaust muffler. Ensure that the pump pressure pipeline system can withstand the highest output pressure achieved and ensure the cleanliness and normal working conditions of the multi-stage pump drive air system. When transporting flammable and toxic fluids, connect the discharge outlet to a safe place away from the work area. Please use a pipe with a smooth inner wall of at least /diameter to connect the exhaust port and muffler.
The high pressure of the fluid may cause serious personal injury and property damage. Please do not perform any maintenance work on the pump and material pipe system when the pump is pressurized. If the rotor pump needs to be repaired, first cut off the pump. Intake air, open the bypass pressure relief mechanism to relieve pressure on the pipeline system, and slowly loosen the connected pipe joints. For example, if the pump transports harmful and toxic fluids or fire pumps, please do not send the pump directly to the manufacturer for repair. The liquid transport part uses a pump made of aluminum alloy. Please do not use it to transport liquids containing +, halogenated hydrocarbons and other halogenated hydrocarbon solvents, otherwise corrosion will occur and the pump body will burst. Ensure that all parts in contact with the conveyor body will not be corroded and damaged by the conveyed fluid. Ensure that all operators are familiar with the operation and use of the pump and understand the precautions for safe use of the pump. If necessary, provide necessary protective equipment. Use the pump correctly and do not allow it to run dry for a long time.
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.
