实用新型名称:一种单螺杆泵 授权公告号 CN 2177823Y 本实用新型为一种单螺杆泵,它由以刚性材料制成的,具有双头螺旋槽圆截面内腔的定子衬套(1)与以刚性材料制成的,具有单螺旋头圆截面的空芯转子螺杆(2)啮合构成。转子螺杆在定子衬套内啮合运动便形成密闭腔的轴向运动,以此可以输送各类流体介质。同现存技术相比,本实用新型自吸能力强,容积效率高,节能明显,振动噪声小,能够以很短的啮合长度获得很高的压力输出。能输送各类高、低温、强腐蚀、强溶剂性流体介质。
Utility model name: a single screw pump authorized notice number CN 2177823Y The utility model is a single screw pump, which is made of a rigid material, having a double helix groove circular cross section of the inner cavity of the stator liner (1) and The hollow-core rotor screw (2) made of a rigid material and having a single-screw head circular cross-section is meshed. Rotor screw in the stator sleeve meshing motion will form a sealed chamber of the axial movement, which can transport all types of fluid medium. Compared with the existing technology, the utility model has the advantages of self-absorption capability, high volumetric efficiency, obvious energy-saving, low vibration and noise, and high pressure output with a short meshing length. Can transport all kinds of high, low temperature, strong corrosion, strong solvent fluid medium.
