It break the limit of generally no allowance for single pump operation in Hungary,and is a pioneer in the similar air cooling units both here and broad.

Research on Enveloping Boring Method for Inner Spiral Surface of Single Screw Pump Stator;

Design and application of GD135-3 type supper-short single screw pump;

Running faulty and type selection process are introduced for the slurry pump in phosphoric acid tank area, summarization is made for type selection of slurry pump, as well as for application effect after its reformation; by means of reformation for coupling of single screw pump imported, running rate is increased by 1% , phosphoric gain rate is increased by 3%.

Startup torque dynamic model of single progressive cavity pump in surface-driven pumping system;

The stator of the general single progressive cavity pump is studied in this paper,using finite element analyzing software,at 5 MPa uniformity pressure of the stator,which concluded the stress,the strain and inner-figure deformation of the progressive cavity pump stator,the stator rubber and the stator steel thimble.

The rules of the single progressive cavity pump pressure modeling and transfering were studied based on the theory analysis.
