Description

TECHNICAL FIELD

[0001] The utility model relates to a kind of radial tile adjusting tools of shaft seal pump. BACKGROUND

[0002] Radial tile is the reactor shaft seal main pump nuclear first component, under the normal operation state of main pump, the water temperature in pump shell is as high as 290 degrees Celsius, pressure rises to 15Mpa, lower pump shaft, impeller and impeller cover in pump shell do not displace under high temperature and high pressure, mainly motor shaft system and pump component shaft system center degree requirement precision is high, circumferential runout value is small, wherein radial tile is the important bearing component of motor shaft system limitation.Radial tile is 5 in total, if the position pitch circle of each radial tile is different, it will affect the center degree of motor shaft system, thereby affecting the running track of the axis of entire motor and pump system, causing the vibration of main pump.To ensure the running track of the axis of motor-pump system, in the process of adjusting radial tile, the position pitch circle of each radial tile must be made same. SUMMARY

[0003] The utility model aims at providing a kind of radial tile adjusting tools of shaft seal pump, ensure the same position pitch circle in the process of adjusting radial tile, by installing measuring device on the tool inner cavity, ensure that radial tile is controllable in the process data.

[0004] The utility model technical scheme is as follows: a kind of radial tile adjusting tools of shaft seal pump, radial tile adjusting tool (2) is thin-walled cylindrical ladder shape, upper end diameter is large, lower end diameter is small, radial tile adjusting tool (2) lower plane is tightly attached on the bottom plate (4) of upper bearing chamber (5), the clearance between the upper end of radial tile adjusting tool (2) and cover ring (6) is equipped with same thickness plug gauge (7) to be fixed, by wedge block (10), connecting sleeve (11), fixed distance block (12), screw (13), washer (14), bearing (15), loctite glue (16), screw (17) and screw (18) form radial tile (3) support, adjusting bolt (8) and the nut (9) of equipped with each other move adjusting wedge block (10) axial movement, wedge block (10) is tapered surface, wedge block (10) drives connecting sleeve (11) to push radial tile (3) and moves in radial direction, the inner surface of radial tile (3) is in contact with the table head of mechanical dial gauge (1), mechanical dial gauge (1) reading produces change, and then adjust the position of radial tile (3).

[0005] The working principle of the utility model is as follows:

[0006] First, according to the outer diameter of motor shaft sleeve, the outer diameter of radial tile adjusting tool is processed, by tightly attaching radial tile on the surface of tool outer diameter, the reading of mechanical dial gauge is zeroed, to determine the deviation value after adjustment.Using this radial tile adjusting tool, the gap between radial tile inner diameter and motor shaft sleeve outer diameter can be controlled by mechanical dial gauge value.

[0007] The utility model discloses the beneficial effect is:

[0008] Utilize the fixed mode of cover ring and radial tile adjustment tool, can according to the mechanical dial reading on radial tile adjustment tool, adjust the clearance of radial tile and motor shaft sleeve.The utility model design drives the axial movement of wedge by the adjustment of bolt and nut, since wedge is conical surface, drives the radial movement of radial tile by connecting sleeve, satisfies the clearance adjustment of each set of radial tile relative to motor shaft sleeve, and can control the value well.The utility model can accurately adjust the radial clearance of radial tile relative to motor shaft sleeve and quantization.The utility model has obtained the application in the installation of multiple products, and the practical effect is good, reaches the expected effect of nuclear main pump installation.
