Technical field
The utility model belongs to pressurized-water reactor nuclear power plant, Steam Turbine in Fire Power Plant etc. and measures the relevant specific purpose tool of absolute altitude.
Background technology
Unit is installed and the maintenance period at steam turbine, all will measure the absolute altitude of bearing shell, to guarantee unit safety stable operation.
The utility model for the steam turbine that uses of unit for HN650-6.41 type, provided by Harbin Turbine, be characterized in separator in the middle of single shaft, four cylinder six steam discharges, band, reaction condensing turbine.Steam-turbine unit is divided into high pressure cylinder, low pressure I～III cylinder.Rotor is connected by shaft coupling, and rotor-support-foundation system is bearing on bearing.
The absolute altitude of steam turbine, refers to the central point of steam turbine bearing and the distance of bearing top.The large young pathbreaker of absolute altitude directly affects the centering situation of unit herein, and acts on bearing, and the vibration of rotating shaft of steam turbine is played a decisive role.At steam turbine, repeatedly in service work, the bearing dynamical height of steam turbine all exceeds standard, and has exceeded 0.005mm, and the work of measuring absolute altitude has repeatability.The factor of General Influence steam turbine absolute altitude is a lot, mainly contains shaft coupling centering situation, coupling bolt moment and tight situation, bearing shell is installed defective etc.Therefore, it is most important that level measurement seems, also there is no to measure specially at present the instrument of absolute altitude, is difficult to increase work efficiency, and ensures measurement quality.
Summary of the invention
The purpose of this utility model is to make the special specific purpose tool of measuring turbine bearing pad absolute altitude, is better more convenient for follow-up installation and maintenance activity.
A kind of turbine bearing pad level measurement specific purpose tool, wherein, comprising: sounding rod, measurement piece, bridge gauge support, fastening bolt;
Bridge gauge support is semi-circular bracket, and bottom is installed on the bearing housing cylinder body of the tested turbine shaft of carrying; Semicircular center, top has the through hole of vertical direction, moves up and down the measurement of carrying out absolute altitude for sounding rod;
Sounding rod, by the middle through hole of bridge gauge support, is measured piece and is arranged at sounding rod below, measures piece below and has the contact locating surface contacting with axle journal;
Bridge gauge support is arranged on the bearing housing cylinder body of carrying measured bearing.
A kind of turbine bearing pad level measurement specific purpose tool as above, wherein, bridge gauge support bottom has level contact locating surface, contact locating surface compression with the upper level of the bearing housing cylinder body that carries tested bearing shell, fastening bolt by two ends, bridge gauge support bottom and described cylinder bolt hole are carried out fastening, carry out the fixing and location of bridge gauge support.
By using this cover specific purpose tool, can farthest avoid people because of error, and installation and simple to operate, DATA REASONING is accurate, can increase work efficiency.

Embodiment
Below in conjunction with drawings and Examples, the utility model is described further.
As shown in Figure 1, this cover turbine bearing pad level measurement specific purpose tool is mainly made up of sounding rod 1, measurement piece 2, bridge gauge support 3, fastening bolt 4 (not shown).
Measure components: sounding rod 1, by the middle through hole of bridge gauge support 2, is measured piece 2 and is arranged at sounding rod 1 below, can adjust up and down and measure piece 2 positions to axle journal place, measures piece 2 and contacts with axle journal; So, carry out mark for sounding rod 1 and the overlapping position of bridge gauge support 2 belows, top, then just can measure the distance of axle journal to bridge gauge support 2.
Bridge gauge holder part: bridge gauge support 3 bottoms have level contact locating surface, can directly contact locating surface compression with the upper level of the bearing housing cylinder body that carries tested bearing shell, and the fastening bolt 4 by bridge gauge support 3 two ends, bottom carries out fastening with cylinder bolt hole, bolt is matched by bolt hole and described cylinder bolt hole, carry out the fixing and location of bridge gauge support 3.
The material of this cover turbine bearing pad level measurement specific purpose tool is Q235A cast steel, is welded by two block plates, and the median surface of crane span structure, the surface level depth of parallelism at two ends require as 5mm/m, and interstitial hole is directly holed, the direct bore hole in the hole at two ends forms.
By adjusting the height of sounding rod, can directly react the absolute altitude of shaft.
Described turbine bearing pad level measurement specific purpose tool using method is as follows:
1) turbine bearing pad level measurement specific purpose tool is taken to on-the-spot;
2) by the axle journal of axle to be measured and around parts clean out, and smear steam turbine oil;
3) turbine bearing pad level measurement specific purpose tool is arranged on bearing box of steam turbine cylinder body by bolt;
4) sounding rod 1 is penetrated from the middle through hole of turbine bearing pad level measurement specific purpose tool;
5) slowly that the measurement piece 2 of sounding rod 1 below is close until contact to axle journal top;
6) repeatedly measure the distance in the bridge gauge support 2 central upper portion holes of axle journal and turbine bearing pad level measurement specific purpose tool, and average, as bearing shell elevation data.
Above embodiment of the present utility model is explained in detail, above-mentioned embodiment is only optimum embodiment of the present utility model, but the utility model is not limited to above-described embodiment, in the ken possessing those of ordinary skill in the art, can also under the prerequisite that does not depart from the utility model aim, make a variety of changes.
