Principle of QB metal double diaphragm pump
>In the two symmetrical working chambers of the metal diaphragm pump, an elastic diaphragm is installed in each. The connecting rod integrates the two diaphragms into one, and the compressed air flows from the air inlet joint of the pump. Finally, the diaphragms in the two working chambers are pushed to drive the two diaphragms connected by the link to move synchronously. At the same time, the gas in the other working chamber is discharged from the back of the diaphragm and out of the pump. Once you reach the end of your trip. The air distribution mechanism automatically introduces compressed air into another working chamber and pushes the diaphragm to move in the opposite direction, thus forming a synchronous reciprocating motion of the two diaphragms. Each working chamber is equipped with two one-way ball valves. The reciprocating motion of the diaphragm causes a change in the volume of the working chamber, forcing the two one-way ball valves to open and close alternately, thereby continuously sucking in and discharging liquid.
>Advantages of QB metal double diaphragm pump
>. Because it is powered by air, the flow rate is automatically adjusted with changes in back pressure (outlet resistance), and is suitable for medium and high viscosity fluids. The working characteristics of centrifugal pumps are set based on water. If they are used for fluids with slightly higher viscosity, they need to be equipped with a reducer or frequency converter, which greatly increases the cost. The same is true for gear pumps.
. The use of pneumatic pumps is reliable and low-cost in flammable and explosive environments, such as the transportation of fuel, gunpowder, and explosives, because:
First, it is impossible to generate sparks after grounding
Second 2. No heat is generated during operation, and the machine will not overheat. Third, the fluid will not overheat because the diaphragm pump causes minimal agitation of the fluid.
. In places where the work is harsh, such as construction sites, industrial and mining wastewater discharge, due to the large number of impurities and complex composition in the sewage, the pipes are prone to blockage, which causes an overload on the electric pump and the motor heats up day by day. damage. The pneumatic diaphragm pump can pass particles and the flow rate is adjustable. When the pipeline is blocked, it will automatically stop until it becomes unblocked.
. In addition, the diaphragm pump is small and easy to move, does not require a foundation, occupies a small area, and is easy and economical to install. Can be used as a mobile material transfer pump.
. In the processing of hazardous and corrosive materials, the diaphragm pump can completely isolate the materials from the outside world.
. Or ensure that no impurities contaminate the raw materials in some experiments.
. Can be used to transport fluids with relatively unstable chemical properties, such as photosensitive materials, flocculation liquids, etc. This is due to the low shear force of diaphragm pumps.
