Circular gear pump structure characteristics
Circular arc gear pump is considered to be the most advanced pump Consecutive contact with the gear, that is, double arc plus sinusoidal compound into tooth shape, can be completely eliminated involute gear pump. Won the national major scientific and technological achievements project, and won the third prize of progress of science and technology by the State Education Commission. Circular arc gear pump in the meshing between the two teeth for a little continuous contact, will not produce trapped oil phenomenon, completely solve the involute gear pump due to oil pump vibration, noise, bearing load increases and so on. Therefore, circular gear pump with efficiency, low noise, and has a good energy saving effect. This series of gear pump gear, shaft, pump body, pump cover, bearing sleeve, shaft seal and other components. Gear with double arc sinusoidal tooth shape manufacturing. Compared with the involute gear, the most outstanding advantage is that there is no relative sliding of the tooth profile during gear meshing. Therefore, the tooth surface has no wear, smooth operation, no liquid trap phenomenon, low noise, long service life and high efficiency. Circular arc gear pump to get rid of the shackles of the traditional design, making the gear pump in the design, production and use into a new field Circular arc gear pump with safety valve as overload protection, safety valve full back pressure of the pump rated discharge pressure 1.5 times. Can also be allowed to discharge pressure within the scope of the actual need to be adjusted. But note that the safety valve can not be a long-term work of the valve, if necessary, can be installed separately in the pipeline. Circular gear pump shaft seal is designed in two forms, one for the mechanical seal, one is the packing seal, according to the specific use and user requirements identified.
