Description

Pump installation structure

Technical field

The invention belongs to the installation structure of the water pump, and relates to the improvement of the assembly structure of the pump body and the mounting seat, and particularly relates to a water pump installation structure capable of adjusting the orientation of the water outlet of the pump body to be conveniently connected with the pipeline.

Background technique

Water pumps for use in aquariums, garden ponds or aquaculture ponds are conveniently installed and used, usually with mounts for mounting the pump on the bottom of the tank or on the mounting bracket.

In the prior art, the mounting seat can be directly integrated with the pump casing, or can be fixed by the screw and the pump casing, and can be adjusted after being assembled together, so that the position and direction between the water outlet of the pump casing and the mounting seat can be adjusted. It is also relatively fixed. Once the position or orientation of the water outlet needs to be adjusted, only the direction of the mounting surface of the mount can be changed.

Usually, the bottom surface of the mount is mounted on the bottom wall of the pool. Since the water outlets of most pumps are arranged in a direction perpendicular to the bottom surface of the mount, the water outlets of most pumps are oriented perpendicular to the bottom wall of the pool.

The use of a pipe connection pump in the pool to direct the water out of the pool will often lead to the lateral direction of the water outlet to the sides of the pump, and the existing outlet orientation cannot be adjusted during use, which will cause trouble for the installation of the pipeline. It is easy to bend the pipe during the process and/or need to use elbows or hoses to change the direction of the water, which not only increases the loss of water flow, but also increases equipment costs and/or operating costs.
