无泄漏泵制造技术

本发明专利技术涉及一种无泄漏泵，包括垂直设置的泵体，所述泵体包括电机、与电机连接的叶轮和密封腔，所述电机包括设置在中心位置的电机轴、设置在电机轴外侧的电机转子、设置在电机转子外侧的电机定子和设置在电机定子外侧的电机外壳；所述密封腔包括：上腔和下腔，所述上腔设置在所述电机外壳内；所述下腔设置在所述电机外壳下方，围设在所述叶轮外，上腔和下腔导通连接；所述下腔下侧设置有进口，旁侧设置有出口。本发明专利技术提供的无泄漏泵采用上、下密封腔以及腔颈的结构，直接由电机轴带动叶轮旋转，从而驱动液体流动，结构简单，效率较高；并且在密封腔内充入适量气体，流体不会与电机转子接触，能够输送高（低）温、有腐蚀性和有铁磁性的流体。

Leak free pump

The invention relates to a non leakage pump comprises a pump body is vertically arranged, the pump body comprises a motor connected with the motor, the impeller and the seal cavity, wherein the motor arranged in the center position of the motor shaft, motor rotor and motor shaft is arranged in the outer stator rotor is arranged in the outside and set in the outer casing of the motor stator; the sealing cavity comprises upper and lower chambers, the upper chamber is arranged in the motor casing; the lower set at the lower part of the motor shell around is arranged on the impeller, the upper and lower chambers are connected; the lower side is provided with imports. The side outlet is arranged. No leakage of the pump by the upper and lower sealing cavity and neck cavity structure provided by the invention, directly from the shaft of the motor drives the impeller to rotate, thereby driving the liquid flow, simple structure and high efficiency; and the amount of gas filled in the sealing cavity, the fluid does not contact with the rotor of the motor, can transfer high (low) temperature, corrosive and ferromagnetic fluid.
