AI Technical Summary
Due to the insufficient length of the center timing meter rack of different models of circulating slurry pumps and the difference in size of the pumps leads to a large number of false shafts, which affects maintenance efficiency and accuracy.
Design a circulating slurry pump center alignment tool that includes a false shaft, a dial meter or a dial meter and a round bottom plate. The length of the false shaft is the average distance of the backrest wheel of the pump, and the fixed hole is distributed on the bottom plate and the pump wheel hole is paired. Improve accuracy.
It improves maintenance efficiency and the accuracy of center alignment, providing guarantees for the safe and environmentally friendly operation of the equipment.

Abstract
Description
Technical Field
[0001] The invention relates to a power plant, in particular to a circulating slurry pump wheel center alignment tool. Background Art
[0002] For different types of circulating slurry pumps that all use intermediate shafts and double diaphragm elastic couplings, the table frame is not long enough when centering, and the size of the backrest wheels of the two types of pumps and the distance between the backrest wheels during infrastructure installation are different. In order to accurately center, multiple dummy shafts of different sizes need to be processed. Too many dummy shafts not only take up space, but also easily cause confusion, affecting maintenance efficiency. Summary of the invention
[0003] The invention provides a circulating slurry pump wheel center alignment tool, aiming to solve the above problem.
[0004] The technical solution of the present invention: A circulating slurry pump wheel center alignment tool, the alignment tool includes a dummy shaft and at least one dial indicator or micrometer, each dial indicator or micrometer is installed at the front end of the dummy shaft; the alignment tool also includes a base plate, the base plate is distributed with a plurality of groups of fixing holes, each group has at least three fixing holes, which are distributed on a circle and match the fixing holes on the back wheel of a circulating slurry pump of a certain size specification, the circle is concentric, the dummy shaft is located at the center of the circle, and the end is fixed to the base plate.
[0005] As a refinement of the above technical solution, when the number of the dial indicators or micrometers is ≥2, each dial indicator or micrometer is symmetrical about the center of the false axis.
[0006] As a refinement of the above technical solution, the bottom plate is a circular bottom plate, and its center is the center of the circle.
[0007] As a refinement of the above technical solution, the dial indicator or micrometer adopts a fixed meter frame, and the fixed meter frame is fixedly connected to the dummy shaft.
[0008] In a refinement of the above technical solution, the length of the dummy shaft is the average distance between the back wheels of the circulating slurry pump.
[0009] In a refinement of the above technical solution, each group of fixed holes is radially staggered.
[0010] The invention has the advantages of reasonable design and ingenious conception, which improves the maintenance efficiency and the accuracy of center alignment, thus providing a certain guarantee for the safe and environmentally friendly operation of the equipment.

[0011] Figure 1 This is the front view of the circulating slurry pump wheel center alignment tool (the dial indicator is omitted).
[0012] Figure 2 This is a top view of the circulating slurry pump wheel center alignment tool (the dial indicator is omitted).
[0013] In the figure, there is a circular bottom plate 1, a fixing hole 1-1, a false shaft 2, and a fixed table frame 3. DETAILED DESCRIPTION
[0014] like Figure 1-2 As shown, a circulating slurry pump wheel center alignment tool, the alignment tool comprises a circular bottom plate 1, a dummy shaft 2, and two dial indicators. The circular bottom plate 1 is provided with three groups of fixing holes 1-1, each group of four fixing holes 1-1, which are distributed on a circle and match the fixing holes on the back wheel of a circulating slurry pump of a certain size. The circle is concentric, and its center is the center of the circular bottom plate 1. The dummy shaft 2 is located at the center of the circle and the end is fixed on the circular bottom plate 1. The two dial indicators are respectively mounted on the front end of the dummy shaft 2 through a fixed meter frame 3, and the two dial indicators are symmetrical about the center of the dummy shaft 2; the length of the dummy shaft 2 is the average distance between the back wheels of the circulating slurry pump; and each group of fixing holes 1-1 is radially staggered.
