[0030] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0031] Example 1:

[0032] Please see Figure 1 The mounting mechanism for adjusting the shims of the compressor unit includes: a bracket 1, on which a connector 2 is mounted, and the connector 2 is fixed on the shaft of the compressor unit, high-pressure pump, and generator set (referring to the adjusting shaft and the reference shaft), thereby mounting the bracket 1 on the shaft of the compressor unit, high-pressure pump, and generator set; a mounting part 4 is mounted on the end of the bracket 1, and a clamp 5 is provided on the mounting part 4 for fixing the dial indicator.

[0033] Please see Figure 1 , Figure 3 and Figure 4The bracket 1 is equipped with a mounting box 6. A coiled rod 15 is rotatably mounted inside the mounting box 6. A connecting rope 10 is wound around the coiled rod 15. A fixing element 11 (which can be a magnet or a clip, etc., allowing it to connect to the mounting area) is located at the end of the connecting rope 10 away from the coiled rod 15. A cam 12 is rotatably mounted on the mounting box 6. One end of the coiled rod 15 extends to the outside of the mounting box 6 and connects to the cam 12. A groove 13 is formed on the cam 12. A limiting element 7 is provided on the mounting box 6. A slot 71 is formed on the side of the limiting element 7 facing the cam 12, and a protrusion for insertion into the groove 13 is provided in the slot 71. The fixing element 11 is fixed to the compressor unit, high-pressure pump, generator set, or other areas, preventing the fixing element 11 from moving. As the shafts of the generator set, high-pressure pump, and generator set rotate (i.e., the adjusting shaft and reference shaft rotate), the dial indicator rotates, and components such as bracket 1 and mounting box 6 also rotate. Since the fixing part 11 does not move, the connecting rope 10 is released from the outer wall of the winding rod 15, causing the winding rod 15 to rotate with the cam 12. This causes the cam 12 to enter the slot 71, and the protrusion to insert into the groove 13, thus limiting the rotation of the cam 12. Continuing to rotate the adjusting shaft and reference shaft causes the cam 12 to continue rotating, moving the protrusion out of the groove 13. During the continued rotation of the cam, the protrusion will re-insert into the groove 13, further limiting the rotation of the cam 12 and serving as a marker (when the protrusion is in the groove 13, it represents the value the dial indicator needs to measure, e.g., ...). Figure 6 As shown, the parameter values ​​corresponding to points a1, a2, a3, a4, b1, b2, b3, and b4 are defined. By limiting the cam 12, misalignment is prevented during the measurement process, ensuring the accuracy of the acquired parameters and making the measurement results more precise.

[0034] In this embodiment, as a further optimization, please refer to... Figure 3 A touch switch is provided in the slot 71, and an indicator light 14 (LED light) is provided on the cam 12. The indicator light 14 is electrically connected to the touch switch through a wire. When the protrusion enters the groove 13, the protrusion will press the touch switch, which will make the indicator light 14 light up, which serves as a prompt. By observing whether the indicator light 14 lights up, it can be determined whether the position is accurate when acquiring parameters, thus ensuring the accuracy of parameter acquisition.

[0035] In this embodiment, as a further optimization, please refer to... Figure 5The connecting rope 10 is equipped with an extension rod 16. The end of the extension rod 16 away from the connecting rope 10 is connected to the fixing member 11. The connecting rope 10 is equipped with a fixing mechanism, which is a mechanism for fixing the extension rod 16 to the connecting rope 10 (the fixing mechanism refers to a fixing strap or other mechanism that can fix the extension rod 16). By moving the extension rod 16, the position of the fixing member 11 is changed, so that the connecting rope 10 will not be released from the outer wall of the winding rod 15 during the process of connecting the fixing member 11 to the installation area, ensuring that the winding rod 15 and the cam 12 will not rotate before the test.

[0036] In this embodiment, as a further optimization, please refer to... Figure 1 and Figure 2 The fixture 5 is equipped with a first lens 8 and a second lens 9; the image on the dial of the dial indicator is projected onto the first lens 8 and the second lens 9, making it convenient to read the parameters on the dial indicator; and the first lens 8 and the second lens 9 are movably mounted on the fixture 5, so that the angles of the first lens 8 and the second lens 9 can be adjusted.

[0037] In this embodiment, as a further optimization, please refer to... Figure 1 The bracket 1 includes a support rod 101 and a movable rod 102. The end of the support rod 101 is provided with a mounting hole, and the movable rod 102 is slidably inserted into the mounting hole. The support rod 101 is provided with a bolt, and the fastening end of the bolt is in contact with the outer wall of the movable rod 102 to fix the movable rod 102. By loosening the bolt and moving the movable rod 102, the length of the bracket 1 can be adjusted according to the requirements.

[0038] In this embodiment, as a further optimization, please refer to... Figure 1 The connector 2 includes two sets of mounting blocks; the two sets of mounting blocks are interlocked with each other, and the bracket 1 is screwed with a screw 3 connected to one set of mounting blocks; by rotating the screw 3, the distance between the connector 2 and the bracket 1 can be adjusted to ensure that the connector 2 can be installed on the shaft of the compressor unit, high-pressure pump, or generator set.

[0039] The calculation method for adjusting the shims of a compressor unit using a single gauge, and the installation mechanism for adjusting the shims using a single gauge, specifically includes the following steps:

[0040] S1: Install the connecting parts 2 of the two brackets 1 on the adjusting shaft and the reference shaft respectively, and then fix the two dial indicators for measurement on the two mounting parts 4 respectively;

[0041] S2: Install the fastener 11 in the fixed area, rotate the adjusting shaft and the reference shaft, and rotate the bracket 1 and the mounting box 6 together to release the connecting rope 10 from the outer wall of the winding rod 15, drive the winding rod 15 to rotate the cam 12, so that the protrusion is inserted into the groove 13, read the value on the dial indicator, and then continue to rotate the adjusting shaft and the reference shaft to repeatedly insert the protrusion into the groove 13 and read the value on the dial indicator.

[0042] S3: Next, input the obtained values ​​into the calculation formula to calculate the required shim thickness, and then adjust the shim to the correct position according to the calculated values.

[0043] S4: After adjusting the shims, rotate the adjusting shaft and the reference shaft, and use a dial indicator to re-measure the centering.

[0044] Please see Figure 5 and Figure 6 During the single-table calibration process, S, L 前 L 后 The deviation values ​​measured by the dial gauge are all known values; what we need to find is H. 前 With H 后 Assuming that both target values ​​A and B are zero, the following is true. Figure 7 As shown:

[0045] X = (a3 - a1 + b3 - b1) / 2

[0046] After obtaining the value of X, Y, Z, and H can be obtained using the principle of similar triangles. 前 value.

[0047] X = (a3 - a1 + b3 - b1) / 2

[0048] Therefore, the following conclusions can be drawn:

[0049]

[0050] Similarly, we can conclude that:

[0051]

[0052] Therefore H 前 +(b3-b1) / 2=Y(Y has been calculated above, )

[0053]

[0054] Similarly, we can conclude that:

[0055]

[0056] The calculation yields the result; if H前 If H > 0, the calculation result will be directly added to the shim. 前 <0, subtract the calculated result from the thickness of the shim, H 后 The same applies, but in H 前 and H 后 Simultaneously calculate and adjust the shims accordingly, and then re-measure the centering (rotate the reference axis and the adjustment axis, and test with a dial indicator).

[0057] Among them, H 前 For adjusting the front anchor bolts of the shaft; H 后 For adjusting the rear anchor bolts of the shaft; L 前 To adjust the distance from the shaft end face to the center of the front anchor bolt; L 后 To adjust the distance from the shaft end face to the center of the rear anchor bolt; S is the distance between the two shafts, which is the set value; a and b are dial indicators used when taking bidirectional measurements.

[0058] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
