Abstract

An object of the utility model is to provide a tool for measuring steam turbine speed probe clearance can accurate measuring probe installation clearance in probe installation, improves the accuracy of probe measurement. Is a die with a double concave shape. The upper and lower grooves of the die respectively clamp the probe and the gear. When the probe is installed, the clearance between the probe and the gear is accurately measured, and errors caused by personnel and tools are avoided.

Description

Tool for measuring gap of rotating speed probe of steam turbine
Technical Field
The utility model belongs to the technical field of the probe installation, concretely relates to an instrument for measuring steam turbine speed probe clearance.
Background
The operating state of the rotating speed probe of the steam turbine directly influences the control and protection of the steam turbine, and the installation clearance of the rotating speed probe of the steam turbine plays a decisive role in the measuring accuracy of the rotating speed. During the operation of the unit, the measured data are deviated once due to the accurate installation clearance of the rotating speed probe. When present field installation probe, often measure the installation clearance with the clearance gauge, the clearance gauge is too soft to some clearance gauges have been deformed, probably cause the inaccurate condition of measurement when the probe installation. According to the phenomenon, a special mounting tool can be manufactured, the template with the fixed gap can be manufactured according to the gap requirement for mounting, the gap accuracy is guaranteed, and errors caused by personnel and tools are avoided.
Disclosure of Invention
An object of the utility model is to provide a tool for measuring steam turbine speed probe clearance can accurate measuring probe installation clearance in probe installation, improves the accuracy of probe measurement.
In order to achieve the above purpose, the utility model adopts the technical proposal that:
a tool for measuring the gap between the rotating speed probes of a steam turbine is a biconcave mould.
The upper and lower grooves of the die respectively clamp the probe and the gear.
The utility model discloses the beneficial effect who gains does:
when the probe is installed, the clearance between the probe and the gear is accurately measured, and errors caused by personnel and tools are avoided.
Drawings
FIG. 1 is a schematic view of a tool for measuring the gap of a turbine speed probe;
in the figure: 1. a probe; 2. the tool is used for measuring the clearance of the rotating speed probe of the steam turbine; 3. a gear.
Detailed Description
The present invention will be described in detail below with reference to the accompanying drawings and specific embodiments.
As shown in figure 1, the tool 2 for measuring the gap between the rotating speed probe of the steam turbine is a die in a biconcave type, the upper and lower grooves respectively block the probe 1 and the gear 3, and the gap between the die measuring probe 1 and the gear 3 is measured through different thicknesses.

Claims (2)
