Rotary thread applied to industrial pump

Abstract

The invention discloses a rotary thread applied to an industrial pump, which comprises a stator assembly, a spiral sleeve, a stator triangular thread arranged in the spiral sleeve and a stator arc-shaped surface arranged on the bottom surface of the stator triangular thread, the rotor assembly comprises a screw rod sleeved with the screw sleeve, a rotor triangular thread arranged on the outer side face of the screw rod and a rotor arc-shaped face arranged on the bottom face of the rotor triangular thread. The stator structure and the rotor structure are matched with each other, the threads are triangular, a certain gap exists between the internal threads and the external threads, and the internal threads and the external threads do not need to be meshed, so that meshing and spiral gaps do not need to be accurately controlled, and the abrasion degree is greatly reduced; the conveying reliability of the industrial pump is greatly improved, the service life of the industrial pump is greatly prolonged, and the stability and reliability of the production process are guaranteed.

Description

technical field [0001] The invention relates to the technical field of rotating threads, in particular to a rotating thread applied to an industrial pump. Background technique [0002] The rotating helix of the screw pump is a twist-shaped helix. Two or more side-by-side screw rods or inner and outer helices are mutually engaged. The requirements for the processing accuracy and helix clearance of the helix are relatively strict, and the structural design of such mutual engagement is more wear-resistant. It is easy to fail in practical applications, which greatly increases the cost of equipment use and maintenance. For this reason, we propose a rotary thread for industrial pumps. SUMMARY OF THE INVENTION [0003] Therefore, the purpose of the present invention is to provide a rotary thread applied to an industrial pump, through the mutual cooperation of the stator structure and the rotor structure, the thread adopts a triangle, and there is a certain gap between the inner a...

[0002] The rotary screw of the screw pump is a twist-shaped screw. Two or more side-by-side screw rods or inner and outer helices are interlocking. The requirements for the machining accuracy and screw clearance of the helix are relatively strict, and the structural design of such interlocking structure is relatively wear-resistant. Large, it is easy to fail in practical applications, which greatly increases the cost of equipment maintenance. For this reason, we propose a rotary screw thread for industrial pumps
