Description

Technical Field

[0001] This invention relates to the field of centrifugal pump technology, specifically to an assembly device for a large corrosion-resistant and wear-resistant centrifugal pump and its usage method. Background Technology

[0002] Centrifugal pumps work by using the rotation of an impeller to cause water to move in a centrifugal motion. Before starting the pump, the pump casing and suction pipe must be filled with water. Then, the motor is started, and the pump shaft drives the impeller and water to rotate at high speed. The water undergoes centrifugal motion and is thrown towards the outer edge of the impeller, flowing into the pump's discharge pipe through the flow channel of the volute casing.

[0003] A centrifugal pump with high efficiency and energy saving function, as disclosed in Chinese Patent CN115199584B, includes a base plate on which a motor and a pump body are mounted. The motor is connected to the pump body via a connecting frame and a flange. An input pipe is connected to the input port of the pump body, and an output pipe is connected to the output port of the pump body. A drive shaft is connected to the output end of the motor. A through hole is provided on the pump body, through which the drive shaft passes and is connected to an impeller body inside the pump body. A cone block is installed on the side of the impeller body near the input pipe. By running the motor, the motor drives the impeller body inside the pump body to rotate at high speed via the drive shaft, creating a negative pressure inside the pump body. This allows liquid to be drawn from the input pipe. When the liquid in the input pipe flows rapidly into the pump body, it impacts the cone block. The inclined surface of the cone block effectively diffuses and guides the liquid in all directions, reducing the impact force of the liquid on the impeller body and avoiding excessive energy consumption.

[0004] In existing centrifugal pumps, the internal motor is connected to the flange and pump body via a pipeline for internal transport. The pipeline is continuously wrapped on the outside. Due to the long-term exposure of the pipeline to the outside, it is susceptible to corrosion, which can lead to damage to the outer pipeline and prevent the equipment from being used. This makes the outside of the pipeline prone to damage. Summary of the Invention

[0005] To address the shortcomings of existing technologies, this invention provides an assembly device and a method for using a large corrosion-resistant and wear-resistant centrifugal pump. It has the advantages of being able to wrap and protect the connecting pipes to prevent external corrosion damage and extend service life.

[0015] Preferably, the right side of the protective mechanism is tightly fitted with an electric motor, and the outer wall of the electric motor is tightly fitted with a ventilation mechanism.

[0020] Compared with the prior art, the present invention provides an assembly device and a method for using a large corrosion-resistant and wear-resistant centrifugal pump, which has the following beneficial effects:

[0021] The assembly equipment and usage method of this large corrosion-resistant and wear-resistant centrifugal pump allow for positioning and fixation using the internal placement plate and bottom-connected mounting and support mechanisms. The internal protective mechanism can be installed and fixed.

Simultaneously, internal fixing screws can be inserted into the descending and ascending cylinders and rotated to fix them, directly wrapping and securing the internal conveying pipeline for external protection. This ensures external isolation during placement. To prevent corrosion and damage to the internal conveying pipes and extend the service life of the external pipes, the support mechanism can be positioned and fixed during operation. It also provides support and fixation around the perimeter during use. There are four internal support mechanisms distributed around the perimeter for enhanced stability. During operation, the internal fasteners can be directly rotated to disassemble and install the internal support mechanisms, facilitating adjustment and installation. During installation, the internal bolts can be inserted into the protruding plates and rotated to install and remove the protruding plates. The pump is fixed to both sides for easy rotation and operation. It can be started using an internal electric actuator, which is height-adjustable to allow for different heights on the left and right sides. This allows for angle adjustment when connecting to external pipelines, improving the pump's operability. The pump is secured to the mounting mechanism using internal locking posts, enabling easy installation and disassembly. A reinforcing weld at the bottom further enhances the connection. Stability is ensured, making placement operations more stable. During operation, internal welded blocks connect and secure the surrounding structure, working in conjunction with internal stabilizing frames and extension plates for stable support and enhanced stability at the bottom. The internal motor can be started during operation, and the external ventilation mechanism provides external protection. During operation, internal fixing bolts can be directly inserted into the cover assembly for rotation, installation, and removal. Internal venting plates facilitate exhaust from the motor fan, while the external cover assembly provides end protection. Attached Figure Description
