Description

Technical Field

[0001] The utility model relates to the technical field of coupling of submersible sewage pumps, in particular to a coupling device using an I-shaped rubber ring. Background Art

[0002] Submersible sewage pump is a submersible sewage pump, which is particularly suitable for conveying liquids containing hard solids, fibers, and particularly dirty, sticky, and slippery liquids. After the coupling device of the submersible sewage pump is installed in place, the flange fitting surfaces of the coupling frame and the coupling base are hard-to-hard inclined contact surfaces. In this way, during the operation of the pump, it is inevitable that a part of the conveyed liquid will leak from the flange fitting surface.

[0003] When implementing this technical solution, there are at least the following defects: 1. The coupling bevels of the coupling frame and the coupling base are also hard-to-hard matching, and the two sets of hard-to-hard combinations will also cause a certain degree of bumping during the installation of the pump, which may cause damage; 2. The hard-to-hard matching of the coupling frame and the coupling base during the installation process also requires the coupling bevel and the flange fitting surface to have high surface quality and processing accuracy to ensure the sealing effect. Therefore, we propose a coupling device using an I-shaped rubber ring. Utility Model Content

Secondly, the I-shaped rubber ring is used as a seal, so the processing area and processing accuracy of the coupling bevel and the flange fitting surface can be reduced, further reducing the working hours and processing and manufacturing costs.

[0007] Optionally, an I-shaped rubber ring body is embedded on one side of the coupling frame, and the I-shaped rubber ring body is arranged on the inner edge of the coupling frame.

[0008] By adopting the above technical solution and setting the I-shaped rubber ring body, the loss of water pump flow can be reduced, and the suction effect of the submersible sewage pump body can be further guaranteed.

[0009] Optionally, a coupling slope is provided on an upper end of one side of the coupling base, and an upper port edge of the coupling frame is in contact with the coupling slope.

[0010] By adopting the above technical solution, it is convenient to arrange the coupling bevel, and to facilitate the coordinated installation of the coupling bevel and the coupling frame.

[0011] Optionally, two guide rods are provided, and the guide rods are symmetrically arranged, and the guide rods are adapted to the upper end of the coupling frame.

[0012] By adopting the above technical solution, the cooperation between the guide rod and the coupling frame is facilitated, thereby facilitating the installation and connection between the submersible sewage pump body and the coupling base.

[0013] Optionally, one side of the flange contact surface is matched with one side edge of the coupling frame.

[0014] By adopting the above technical solution, it is easy to ensure the fit between the coupling frame and the coupling base.
