Description

Technical Field

[0001] The utility model relates to the technical field of centrifugal pump seats, in particular to a test seat of a high-stability horizontal centrifugal pump. Background Art

[0002] As the name implies, a horizontal centrifugal pump is one in which the main shaft of the pump is roughly parallel to the horizontal direction of the ground. It is mainly composed of a pump body, an impeller, a blade disc, a shaft, etc. It is a common centrifugal pump, widely used in agricultural irrigation, urban water supply and drainage, industrial production, etc. The working principle of a horizontal centrifugal pump is very simple. When the motor drives the pump shaft to rotate, the liquid enters the pump body through the inlet pipe, is sucked in by the impeller and accelerates the rotation, and then passes through the flow channel of the impeller to transfer the energy with gradually increasing momentum, and finally is discharged from the outlet pipe. The working principle of a centrifugal pump is similar to that of a centrifuge. Under the action of centrifugal force, the liquid is pushed outward by the centrifugal force, thereby realizing the transportation of the liquid.

[0003] Before a centrifugal pump leaves the factory, it is usually necessary to conduct an acceptance inspection to ensure that its performance meets the requirements and can operate normally. During the acceptance inspection, in order to facilitate the installation of centrifugal pumps of different models and sizes, the centrifugal pump is generally fixed on a test stand. The existing patent number CN220228393U proposes a mounting bracket for a centrifugal pump, including a mounting bracket body, the inner side wall of the mounting bracket body is provided with two first slide grooves, and the inner side walls of the two first slide grooves are slidably connected together with two movable mounting plates. However, the above-mentioned centrifugal pump stand only takes into account the difference in the position of the mounting holes of different horizontal centrifugal pump bases, and does not take into account the differences in the mounting hole diameters of different horizontal centrifugal pump bases and the sizes of the equipped fasteners, resulting in a limited range of centrifugal pump models suitable for installation of the above-mentioned stand. For this reason, a test stand for a high-stability horizontal centrifugal pump is proposed. Utility Model Content
