Description

Technical Field

[0001] The present application relates to the field of centrifugal pump seats, and in particular to a special seat for centrifugal pumps and a centrifugal pump. Background Art

[0002] The centrifugal pump is designed based on the principle of centrifugal force. The high-speed rotating impeller blades drive the water to rotate and throw the water out, thereby achieving the purpose of transportation. Centrifugal pumps include vertical and horizontal types.

[0003] The base of the horizontal centrifugal pump is in a frame-shaped configuration, which is used to install the centrifugal pump motor, transmission and centrifugal body. Specifically, the above components are installed on the frame-shaped base through a screw and nut structure. Therefore, during maintenance, a single component can be removed for maintenance. However, the existing frame-shaped base is an integrated setting, so it needs to be transported as a whole during transportation, and the base cannot be disassembled for transportation, which increases the difficulty of transportation to a certain extent. For this reason, we propose a special base for centrifugal pumps and a centrifugal pump. Utility Model Content

The first support is screwed to one end of the two angle steels, and the second support is screwed to the other end of the two angle steels. The support seat assembly is fixedly mounted on the connecting plate.

[0007] In a specific embodiment, the first support and the second support are both U-shaped and matched with the shape of the angle steel, so that the two ends of the angle steel are respectively inserted into the side walls of the first support and the second support.

[0008] In a specific embodiment, a plurality of first connecting holes are respectively opened on the side walls at both ends of the angle steel, and a second connecting hole is respectively opened on the side walls of the first support and the second support, and two of the second connecting holes are respectively arranged corresponding to two of the first connecting holes, and both are connected with locking parts.

[0009] In a specific embodiment, the locking member includes a screw rod arranged through the first connecting hole and the second connecting hole, and a nut is threadedly connected to the screw rod to fix the angle steel with the first support and the second support.

[0010] In a specific embodiment, the support seat assembly includes a T-shaped steel fixedly mounted on the top of the connecting plate, a third mounting hole connected to the transmission is opened on the T-shaped steel, and a plurality of first ribs are connected to the connecting plate.

[0011] In a specific implementation manner, a plurality of second ribs are fixedly installed in the angle steel, the first support and the second support respectively.

[0012] In a second aspect, the present application further provides a centrifugal pump, comprising

[0013] The above-mentioned special seat for the centrifugal pump.
