The pneumatic diaphragm pump for mining uses the pressure difference in the air chamber to The suction liquid pressure and positive liquid pressure are alternately generated in the liquid chamber, and the valve switch is controlled to 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. Pneumatic diaphragm pump manufacturer, one of the three major brands, Dongda Electromechanical produces pneumatic diaphragm pump manufacturers with the cheapest price
Pneumatic diaphragm pump The woman in red stands majestically on the Suzaku Bridge in Chang'an City with a big knife on her back. This is the time of marriage. A place where the sedan chair must pass.
In "Dream Journey", marriage can be luxurious or simple. When Weiwei and Zhen Shui got married, they were very simple, so they went to Yue Lao to have it notarized. At that time, everyone was poor, and they got married for a mission. Pneumatic diaphragm pumps don’t have to worry too much about form. The scene where Zhen Shui and Xiao Yu Yaoyao got married today was undoubtedly a super luxurious pneumatic diaphragm pump.

Overview of pneumatic diaphragm pumps
Pneumatic diaphragm pumps are mainly used for mine tunnel development, shaft shaft construction, sewage discharge around mining working face tanks and various types of equipment, and underground cave chamber projects. Drainage, sewage discharge, sand discharge, mud discharge, mine tunnel whitening application, 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. The pneumatic diaphragm pump manufacturer has the cheapest production price
The structure of the pneumatic diaphragm pump
The pneumatic diaphragm pump is composed of a water outlet manifold, a pump cover, a pump body, a water inlet manifold, a diaphragm, a ball, a ball seat, and an outlet pipe. , slide valve, muffler, piston, air intake pipe, water inlet section, etc.

When the diaphragm pump is running, the lubricating oil pressure should not be lower than the pressure interlock value (), and the lubrication The pressure difference of the oil outlet filter should not be too large, and 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, which will cause the pressure to drop too quickly and cause an interlock trip.
Through the above process improvements and proficiency in operating key points, the diaphragm pump always has a stable process environment when operating. It operates a pneumatic diaphragm pump manufacturer and one of the three major brands, Dongda Electromechanical Production
Over the past few years, the vehicle has only tripped due to electrical reasons, achieving long-term, safe and efficient operation.

The diaphragm pump is driven by a variable frequency motor. If the shutdown load is too large or the Too small, large short-term load fluctuations, long-term operation under low load, etc. all have an impact on the inverter. In order to avoid the above situations, it is rigidly stipulated that the starting and stopping loads are controlled at around %, and the instrument is set to increase the load. Load shedding must be completed within a period of time, effectively achieving the maintenance of the frequency converter from a technical perspective.
Force 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 mist ized.
The company always focuses on the guiding ideology of the National Coal Mine Safety Supervision Bureau on coal mine safety, takes coal mine safety as its own responsibility, and creates safe
