Embodiment
The technical scheme of this patent is described in more detail with reference to embodiment.
Referring to Fig. 1, a kind of single screw rod water pump, including connecting cylinder 1, screw rod 2, star gear body 4 and casing 7, the connecting cylinder 1
It is interconnected and is mutually perpendicular to casing 7, screw rod 2 is arranged in connecting cylinder 1, and the end of screw rod 2 is placed in before the side of casing 7
In bearing block 6, completion is connected with the rotation of casing 7, and the surface of screw rod 2 is provided with multiple spiral helicine screw channels 3, and the spiral shell of screw rod 2
Groove 3 is partially disposed in casing 7, and screw channel 3 is equipped with screw rod as the element volume for carrying water, casing 7 in the both sides of screw rod 2
Multiple blades are uniformly provided with 2 star gear bodies 4 being arranged symmetrically, the excircle of star gear body 4, blade is placed in screw channel 3, star gear body 4 leads to
Cross bearing of planetary gear 5 to be connected with the rotation of casing 7, casing offers water inlet and water outlet respectively at the position of correspondence screw channel 3 end
Mouthful, water inlet and delivery port are connected with screw channel 3, and operationally, liquid is entered in screw channel 3 by water inlet, in the leaf of star gear body 4
Under the lattice gear effect of piece, the volume of element volume is tapered into, and internal liquid is compressed, until screw channel 3 turns to water outlet,
Liquid is discharged.
The screw rod 2 is made of alloyed copper or stainless steel.
The star gear body 4 and blade are made into integration using peek non-metallic materials, excellent with high temperature resistant and mechanical performance
Different characteristic.
The connecting cylinder 1 is provided with shaft coupling resigning 8, for installing the shaft coupling between screw rod 2 and motor.
Bearing lubrication oilhole is offered on the front-end bearing pedestal 6.
The blade quantity ratio of the screw channel 3 and star gear body 4 is 6:11, as prime number is without common divisor so that in gear motion
Even wearing, each blade can each inswept screw channel in turn in motion.
Check valve is installed on the delivery port.
Operation principle of the present utility model is：（1）Water inlet process
Referring to Fig. 2, water is stepped into by water inlet in the screw channel 3 constantly expanded, because the area of water inlet is with respect to spiral shell
The area of groove 3 is big, and water flow velocity is relatively low, and fluid pressure losses can be ignored, therefore regard water absorption course as isobaric procedure；
（2）Compression process
Referring to Fig. 3, while separating water inlet by the blade of star gear body 4, water is in the element volume that screw channel 3 is formed
Pressure is improved by compression（Depending on the pressure of user's request）, untill when element volume and delivery port are connected, this rank
Section is compression process, and the volume of screw channel 3 is gradually decreased, and pressure and temperature constantly rises, and Gu Shui compression process is a multivariable
Thermodynamic process；
