Description

Technical Field

[0001] The present application relates to the technical field of centrifugal pumps, and more specifically, to a novel horizontal centrifugal pump. Background Art

[0002] Centrifugal pumps are available in various types, including vertical, horizontal, single-stage, multi-stage, single-suction, double-suction, and self-priming. Centrifugal pumps work by using the rotation of the impeller to cause the water to undergo centrifugal motion. Before starting the pump, the pump casing and the suction pipe must be filled with water, and then the motor is started so that the pump shaft drives the impeller and water to rotate at high speed. The water undergoes centrifugal motion and is thrown to the outer edge of the impeller, flowing into the water pressure pipeline of the pump through the flow channel of the volute pump casing.

[0003] After searching, it was found that the application number is CN202023293585.0, and the name is a new type of horizontal centrifugal pump. The application proposes an existing horizontal centrifugal pump, including a pump body, a motor and a base plate. The pump body and the motor are generally fixed to the base plate with screws. When the pump body and the motor are working, vibrations will occur, which can easily cause the screws to loosen, resulting in the pump body and the motor being not firmly fixed to the base plate. In addition, when disassembling the pump body and the motor, tools are often required to unscrew the screws from the base plate, which makes the disassembly of the pump body and the motor more troublesome. Through the arrangement of threaded tubes and springs, the pump body and the motor are installed more firmly on the base plate. At the same time, there is no need to use tools for disassembly, making it easier to disassemble the motor and the pump body from the base plate.

[0004] However, the horizontal centrifugal pump is mainly composed of a motor and an impeller compartment, and the motor and the impeller compartment are connected by a flange. During maintenance, the motor or the impeller compartment needs to be removed and then reassembled together. During reinstallation, the bolt holes of the flange need to be realigned. Due to the heavy weight of the motor, it is difficult to align the bolt holes by hand, which is not convenient for reinstallation after maintenance. At the same time, the application needs to remove the threaded pipe when dismantling the split part. The threaded pipe is long and a lot of rotation work needs to be completed. Reinstallation and disassembly are also more troublesome, and further improvements can be made.

[0005] In order to solve the above problems, the present application provides a novel horizontal centrifugal pump. Utility Model Content

[0006] The present application provides a novel horizontal centrifugal pump adopting the following technical solution:

[0007] - tached to said driving mechanism, a floating feeder mounted on 'said mechanism, means for raising and lowering the casing vertically relative to the engine, means for swinging endsat the rear of the sides of said frame, a 49.49 mm / s wait for reciprocating movement of the frame, said mechanism for swinging ends at said mechanism, a 49.49 mm / s wait for reciprocating movement of the frame, said mechanism for swinging ends at said mechanism, a 49.49 mm / s wait for reciprocating movement of the frame,

The impeller bin mounting plate squeezes the first rubber pad until the through hole moves below the blocking block. The blocking block moves outward under the action of the spring, and the impeller bin mounting plate can be clamped, so that the impeller bin main body can be fixed. The installation method of the motor main body is the same as that of the impeller bin main body. This device eliminates the trouble of bolt connection, can quickly complete the fixed installation of the motor main body and the impeller bin main body, and further improves the convenience of installation and use.

[0011] Furthermore, the two ends of the spring are fixedly connected to the inner wall of the side groove and the surface of the clamping block respectively, and the other end of the clamping block is an inclined surface.
