Embodiment 1

[0021] Such as figure 1 Shown is a hydraulic generator air gap measurement tool, the measuring tool is composed of a main ruler, a vernier ruler, a locking screw, and a pair of measuring claws, the main ruler and the vernier ruler are connected by a locking screw, and the measuring claws are respectively It is integrally arranged on the head side of the main ruler and the vernier ruler and is symmetrical to each other. The measuring range of the main ruler is 0-50mm, which is used to measure the hydroelectric generator set with an air gap within the range of 8-50mm; the main ruler is clearly marked The scale range and reading of the scale, the length of the measuring claw is greater than or equal to 300mm, the effective measurement depth is guaranteed to be 300mm, and the accuracy of the vernier is 0.02mm. Such as Figure 5 As shown, the end 1-1 of the main ruler of the measuring tool is a slope and a protrusion is provided for limiting and checking the size. The design of th...

Embodiment 2

[0025] Such as image 3 Shown is a hydraulic generator air gap digital display measuring tool, the measuring tool is composed of a main ruler, a vernier ruler, a locking screw, a pair of measuring claws, a capacitance displacement sensor, and a liquid crystal display screen. The main ruler and the vernier ruler They are connected by locking screws. The measuring claws are integrally arranged on the head side of the main ruler and the vernier ruler and are symmetrical to each other. The measuring range of the main ruler is 0-50mm, which is used to measure the air gap within the range of 8-50mm. Hydrogenerator unit; the main ruler is marked with a clear scale range and reading, the length of the measuring claw is greater than or equal to 300mm, to ensure that its effective measurement depth is 300mm, and the accuracy of the vernier is 0.02mm. Such as Figure 5 As shown, the end 1-1 of the main ruler of the measuring tool is a slope and a protrusion is provided for limiting and ...

Abstract

The invention relates to a measurement tool for an air gap of a water turbine generator set and a measurement method of the tool. The measurement tool comprises a main scale, a vernier scale, a locking screw and a pair of measurement claws. The measurement claws are integrally arranged on the main scale and at one side of the head portion of the vernier scale respectively and symmetric to each other, the locking screw is used for fixing the vernier scale, the measurement range of the measurement tool is within 0-50 mm, the length of the measurement claws is larger than or equal to 300 mm, andit is guaranteed that the effective measurement depth of the measurement tool is 300 mm. The measurement tool is suitable for measuring the water turbine generator set with the air gap of 8-50 mm, andthe problem is effectively solved that the effective measurement length of an existing measurement tool is insufficient, the space of the measurement part is limited, and due to mutual interference,measurement cannot be achieved.

Description

technical field [0001] The invention relates to a measuring tool, in particular to a gap measuring tool for a water turbine generator set and a measuring method thereof, which are mainly suitable for measuring a water turbine generator set whose air gap is within the range of 8-50 mm. Background technique [0002] In the prior art, the air gap measurement method of the hydroelectric generating set is to measure with a wooden wedge ruler and a vernier caliper. Cover the inclined surface of the wooden wedge with colored chalk, insert the inclined surface against the middle of the stator core, press it with a certain force when it cannot be inserted, and then pull it out, and use a vernier caliper to measure the scratches between the inclined surface of the wooden wedge and the stator core The thickness of the vernier caliper is the air gap there. [0003] Since the pressing force exerted by the wooden wedge is difficult to achieve the same size at each measuring point, and it...
