Pneumatic diaphragm pump is the perfect combination of composite technology, overview of the development of pump technology, many are the result of using composite technology. Pneumatic diaphragm pump is the perfect combination of composite technology (1) Centrifugal impeller and vortex impeller, a centrifugal vortex self-priming pump. (2) jet nozzle and centrifugal pump combined to become a centrifugal jet self-priming pump. (3) The combination of pump impeller and turbine runner, to become a water pump. (4) centrifugal pump and piston diaphragm pump combine to form a strong self-priming pump. (5) The inducer and the centrifugal wheel combine to improve the cavitation resistance of the pump. (6) Double suction impeller and single suction impeller combine to solve the cavitation and axial force balance. (7) the length of the blades combined use to solve the plug impeller import and export proliferation issues. (8) The combination of pneumatic pump and positive displacement pump pneumatic diaphragm pump. (9) Short vanes to the back of the long vane, to prevent the axial vortex and outlet flow separation. (10) Downloading of low-lift impeller lifting liquid, the upper body high-lift impeller pressurized long-axis liquid pump (double-wheel liquid pump), to solve long axis liquid pump manufacturing difficulties, unreliable operation (). (11) The mechanical seal static and dynamic ring installed in the last impeller seal ring at the end, as axial force balance device, the use of impeller pressure balance before and after the balance of axial force, as can solve the dynamic and static ring Wear problems, economic benefits are significant. (12) The principle of the balance disc is moved to the impeller rear cover, due to the formation of radial, axial two gaps, the balance can be the same as the disc automatically balance the axial force. When the axial force is large, the impeller moves toward the inlet, the axial clearance increases, the pressure behind the impeller decreases, and the impeller moves backward. vice versa. (13) paste packing seal is a graphite, fiber, tetrafluoroethylene, silicone and other components of the paste, in the course of use, injection gun can be injected (supplement). It is said that in some cases, the effect is good. Although not yet available for use on all pumps, this is a valuable idea that promises to be a breakthrough in sealing technology. (14) Slurry pump impellers with twisted blades may reduce wear due to compliance with flow conditions and increase efficiency. There are numerous successful examples of using composite technologies. To make good use of living composite technologies, it requires a wide range of knowledge and dares to innovate.
