Description

Technical Field

[0001] The invention belongs to the technical field of centrifugal pump manufacturing, and in particular relates to an assembly method of a high-temperature resistant process centrifugal pump. Background Art

[0002] A centrifugal pump is a pump that transports liquid based on the centrifugal force generated by the rotation of the impeller. The centrifugal pump has a certain applicable range for the fluid temperature. When the temperature of the transported fluid is too high, a special high-temperature centrifugal pump is required to operate.

[0003] As the main component of the centrifugal pump, the high temperature resistance of the pump body plays a vital role in the entire centrifugal pump. By making the pump body of high temperature resistant chromium steel material, the high temperature resistance of the centrifugal pump can be improved.

[0004] In the prior art, a centrifugal pump comprises a motor, an impeller, a bracket, a pump body and other components. Due to the large mass of the centrifugal pump, the mass of each component is also relatively large. During the manual calibration and installation process, collisions are easily caused, resulting in damage to the components. In addition, the operation is difficult, the installation accuracy is low, and the installation efficiency is low. Summary of the Invention

[0005] The purpose of the present invention is to solve the above-mentioned technical problems existing in the prior art and provide a method for assembling a high-temperature resistant process centrifugal pump. First, before assembly, the auxiliary mounting table is cleaned and reset. The motor is positioned and installed on the auxiliary mounting table through a limit block. The limit piece and the clamping piece are controlled to limit the motor on the limit block, thereby fixing the motor on the auxiliary mounting table. The setting of the limit block, the limit piece and the clamping piece plays a role in positioning and fixing the assembly of the motor, ensuring the accuracy and stability of subsequent component installation. A slide groove is opened on the auxiliary mounting table, and a sliding groove is set in the slide groove. Seat one and sliding seat two, the clamping adjustment component is fixed on sliding seat one, and the assembly component is fixed on sliding seat two, the clamping adjustment component fixes the bracket on sliding seat one, and the assembly component fixes the pump body on sliding seat two. Since the position of the motor is fixed, the position of the bracket and the pump body is adjusted by the clamping adjustment component and the assembly component to achieve the alignment of the installation position of the bracket with the motor axis, and the center of the circle of the pump body and the bracket connection position. Then, the bracket is installed on the motor through sliding seat one, and then the impeller is installed on the bracket. The rotating shaft of the impeller is connected to the motor shaft, and then the pump body and the bracket are fixedly connected through sliding seat two. The impeller is installed in the pump body, thereby completing the assembly. The assembly is carried out after the installation position is aligned, which greatly improves the installation accuracy. At the same time, the sliding adjustment of the sliding seat one and the sliding seat two facilitates the assembly of the centrifugal pump, avoids collisions between the various components, and is simple and convenient to operate. Then, the limiter, the clamping member, the clamping adjustment component and the assembly component are loosened, and at the same time, the disassembly device pushes the base one by one to the top surface of the auxiliary installation table, and the fixedly connected motor, bracket and pump body are welded and fixed to the hoisting support base to complete the assembly of the centrifugal pump.

[0006] In order to solve the above technical problems, the present invention adopts the following technical solutions:

The limit blocks are clamped in the slots, and the limit members are provided with a limit frame. The bottom of the limit frame is provided with a rotating seat. The rotating seat and the limit block are rotatably connected via a rotating shaft 1. The end of the rotating shaft 1 is screwed into a limit nut 1, and the limit nut 1 is tightened on the rotating seat. A slot matching the limit block is provided on the base. When the motor needs to be fixed on the auxiliary mounting platform, the slot is clamped on the limit block, and then the limit nut 1 is loosened, allowing the limit frame to rotate through the rotating seat, so that the limit frame is tightly attached to one end of the base, thereby limiting one end of the motor.

The lifting frame is used to adjust the height of the support frame, and the support frame is used to support and fix the pump body. The sliding block can drive the lifting frame to slide along the sliding groove, thereby controlling the sliding of the pump body along the groove, thereby adjusting the position of the pump body so that the center of the circle at the connection point between the pump body and the support is aligned.
