. . Overview
Diaphragm pumps are mainly used for mine tunnel development, shaft shaft construction, sewage discharge around mining working face tanks and various equipment, drainage, sewage discharge, sand discharge, mud discharge in underground cave chamber projects, and mine tunnel whitening applications. wait. The diaphragm pump produced by our company adopts, absorbs and improves the most advanced diaphragm pump production technology and technology in the world. This product is specially designed for coal mines and has all the features of traditional submersible electric pumps, mud pumps, impurity pumps and flexible shaft pumps. Function, 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.
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.

Working principle of diaphragm pump
Mining diaphragm pump uses the pressure difference in the air chamber to alternately generate electricity in the liquid chamber. Suction liquid pressure and positive liquid pressure, controlling the valve switch can ensure the 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 Diaphragm Pump
The mining 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, causing the working chamber to produce Pressure difference 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.

Applicable occasions
Since the pneumatic diaphragm pump has the above characteristics, the diaphragm pump has been used in the world since its birth Since then, it has gradually invaded the market of other pumps and occupied part of it. For example, diaphragm pumps have occupied an absolutely dominant position in the spray painting and ceramic industries.
Internal system
Diaphragm pump equipment system consists of one or more double-sided pumps, such as a pneumatic double-diaphragm pump. The manifolds on the pump are split so that each side of the pump pumps one component of the multi-component material, and an accumulator is connected to the output on both sides so that the out-of-phase output of the pump becomes in-phase. Diaphragm isolation valves are optionally available on each side of the pump outlet to prevent backflow of mixed material. If other mixing ratios are required, more than one of these pumps can be used together to achieve multiple mixing ratios.
Diaphragm failure monitoring system is used to detect leakage of the diaphragm pump diaphragm. The system includes a pump having a working chamber containing a working fluid, a pumping chamber for pumping material into and out of the pump and a diaphragm for isolating the working chamber from the pumping chamber. A first optical fiber is connected to the working chamber for transmitting an optical signal through the working fluid. A second optical fiber is connected to the working chamber for receiving optical signals transmitted from the first optical fiber. An electrical signal establishing device establishes the first electrical signal when the optical signal is transmitted from the first optical fiber and passes through the uncontaminated working fluid to the second optical fiber. This electrical signal establishing device establishes a second electrical signal when the optical signal is transmitted from the first optical fiber and passes through the contaminated working fluid to the second optical fiber. When the second electrical signal is established, leakage of contaminated material through the diaphragm into the working chamber can be detected.
The installation method of the diaphragm in the diaphragm pump is based on the geometric dimensions of the diaphragm without affecting the volume change requirements of the pump and making full use of the excellent pressure resistance of the diaphragm. It does not require any additional cost and work. quantity, and greatly improves the service life of the diaphragm, ensures normalization of production and improves product production quality. It can be applied to the installation of diaphragms in various diaphragm pumps.
Production, sales and technical service of diaphragm pumps. Jining Dongda Mechanical and Electrical Co., Ltd. now has ten series and more than 40 varieties of products. The main products are diaphragm pumps, mining diaphragm pumps,
