The G-type single-screw pump belongs to a rotor-type positive displacement pump, which relies on the screw and the bushing to mesh with each other to generate a volume change in the suction chamber and the discharge chamber to transport the liquid. The G-type single-screw pump is an internal meshing hermetic screw pump. The main working components are composed of a bushing (stator) having a double-headed spiral cavity and a single-headed screw (rotor) meshing therewith in the stator cavity. The following problems are often encountered when using a G-type single screw pump: 1. The pump body vibrates or produces noise Cause: The pump is not installed securely or the pump is installed too high; the motor ball bearing is damaged; the pump shaft is bent or not concentric with the motor shaft, and is not parallel. Treatment method: install the pump or reduce the installation height of the pump; replace the motor ball bearing; correct the curved water pump spindle or adjust the relative position of the pump and the motor. 2. The drive shaft or motor bearing is overheated Cause: Lack of lubricating oil or broken bearings. Treatment: Fill with oil or replace the bearing. 3. The pump does not produce water Cause: The pump body and the suction pipe are not filled with water; the moving water level is lower than the water pump water pipe; the water pipe is broken. The sealing surface between the screw and the housing is a spatial curved surface. There is a non-sealed area such as ab or de on this curved surface, and a plurality of triangular notches abc, def are formed with the groove portion of the screw. These triangular indentations form a passage for the liquid, allowing the active screw groove A to communicate with the grooves B, C on the driven screw. The grooves B and C are wound along their own spirals to the back, and communicate with the grooves D and E on the back, respectively. Since the grooves D, E and the groove F (which belong to the other head spiral) are joined to each other, there is also a triangular notch a'b'c' similar to the front surface, so D, F, and E will also communicate. In this way, the groove ABCDEA also constitutes a "∞"-shaped sealed space (if a single-head thread is used, the groove will be screwed in the axial direction, and the suction and discharge ports will pass through, failing to form a seal). It is not difficult to imagine that on such a screw, a plurality of independent "∞"-shaped sealed spaces will be formed, each of which occupies an axial length exactly equal to the lead t of the tired rod. Therefore, in order to separate the screw suction and discharge ports, the length of the threaded section of the screw is at least greater than one lead.
