Click to open the original
Mining The 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 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.

Pneumatic diaphragm pump composition
br/>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, air inlet pipe, water inlet section, etc.
/> 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, 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.
The abstract mainly explains the composition and classification of diaphragm pumps, as well as the selection principles and methods of the type of regulating room, actuator, mode of action, flow characteristics, etc., and analyzes the methods and principles of regulating valve selection.
Keywords control valve, diaphragm pump classification selection analysis
The role of the diaphragm pump in process control is to receive the control signal from the regulator or computer, change the flow rate of the adjusted medium, and maintain the adjusted parameters at the required within the scope to achieve automation of the production process. If the automatic adjustment system is compared with the manual adjustment process, the detection unit is the human eye, the adjustment control unit is the human brain, and the execution unit diaphragm pump is the human hand and foot. To realize the regulation and control of certain parameters of the process, such as temperature, pressure, flow, liquid level, etc., a diaphragm pump is indispensable. Therefore, the correct selection of diaphragm pumps is of great significance in process automation. Pneumatic diaphragm pump manufacturer specializes in production, big brand Dongda Electromechanical

Invention and classification
Diaphragm pump, also known as control pump, is the main type of actuator. It accepts the control signal output from the regulating control unit and uses power operation to change the fluid flow. Diaphragm pumps generally consist of an actuator and a valve. According to the power used by its actuator, diaphragm pumps can be divided into three types: pneumatic, electric and hydraulic, namely pneumatic diaphragm pumps using compressed air as the power source, electric diaphragm pumps using electricity as the power source, and liquid medium pumps. (Such as oil, etc.) pressure-powered hydraulic diaphragm pump.
Selection of type

.Selection of valve body type of diaphragm pump The selection of valve body is the most important step in the selection of diaphragm pump. There are many types of diaphragm pump valve bodies.
The shape and structure of the valve core is mainly considered based on factors such as the selected flow characteristics and unbalanced force.
Abrasion resistance When the fluid medium is a suspension containing a high concentration of abrasive particles.
Corrosion resistance Since the medium is corrosive, try to choose a valve with a simple structure if it can meet the adjustment function.
Temperature and pressure of the medium When the temperature and pressure of the medium are high and change greatly, a valve whose material of the valve core and valve seat is less affected by temperature and pressure changes should be selected.
. Selection of diaphragm pump actuator
Consideration of output force
Regardless of the type of actuator, its output force is the effective force used to overcome the load (mainly refers to unbalanced force and Unbalanced moment plus friction, sealing force, gravity and other related forces).

Overview of pneumatic diaphragm pump
br/> 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. Pneumatic diaphragm pumps are mainly used for mine tunnel development, shaft shaft construction, sewage discharge around mining working face tanks and various equipment, drainage, sewage sand discharge, mud discharge in underground cave chamber projects, mine tunnel whitening applications, 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.
