Embodiment Construction

[0026] Examples are given to illustrate the technical content of the present invention more clearly.

[0027] Production and processing flow chart of the present invention refers to attached figure 1 .

[0028] First of all, put the processed flat belt on the transmission drive disc lightly. After being processed into the required arc shape, it enters the special knife mold and feeds it into the reaming hole in a straight line, adjusts the three reamers, and starts spiral forming. During the process, the positions of the three reamers are constantly adjusted to make the spring hose reach the standard diameter and pitch. After ensuring that the pitch of the spring hose and the dimensions of the inner and outer diameters are stable, enter the take-up device, and refer to the attached drawing for the forming diagram of the crankshaft spring hose in the form of an arc. figure 2 , for a cross-section see the attached image 3 . Start the take-up reel, and wind the coiled spri...

Abstract

The invention relates to the field of nuclear power station neutron-flux measurement system, and specifically provides a concave hose in a driving spiral flexible shaft. The crankshaft spring hose can be used in a portable miniature fission chamber detector. The high-quality arc crankshaft spring hose is produced by steps of material selection, arc moulding, spiral moulding and wire rewinding. In addition, the produced spring hose has a qualified dimension, and hardness and tensile strength which satisfy application demands.

Description

technical field [0001] The invention relates to the field of a nuclear power plant reactor core neutron flux rate measurement system, in particular to a concave flexible shaft for driving a spiral flexible shaft. For mobile miniature fission chamber detectors. Background technique [0002] Nuclear power plant core neutron flux rate measurement system, such as a mobile miniature fission chamber as a detector, "drive spiral hose" is an important accessory for the detector, because it depends on it in high radiation, high temperature (350 ℃) environmental conditions Next, the detector is accurately sent into and out of the core to measure the neutron flux rate at each point of the reactor. Therefore, higher requirements are put forward for the material, heat treatment, hardness, strength, geometric shape, and process of the "drive spiral hose". It consists of three layers: the inner layer is a hollow hose with a concave section, the middle layer is wrapped with 20 steel wires...
