Portable minimally invasive sampling machine and application thereof

Abstract

The invention discloses a portable minimally invasive sampling machine and application thereof. The portable minimally invasive sampling machine comprises an air compressor, an air conveying pipe, an arc-shaped milling cutter, a pneumatic motor, a swinging mechanism, an adjusting mechanism, a fixed support and a locking chain; the whole machine is fixed on a test sample to be sampled by the fixed support and the locking chain; the distance between the arc-shaped milling cutter and the surface of the test sample is adjusted through the adjusting mechanism; and the pneumatic motor and the swinging mechanism are driven by the air compressor respectively so that the arc-shaped milling cutter is driven to carry out efficient minimally invasive sampling on the surface of the test sample. According to the technical scheme, aiming at in-service equipment at a high temperature, the tiny test sample can be cut from the in-service equipment in an efficient and minimally invasive manner, and tissues of metal materials have no damages; and the portable minimally invasive sampling machine can also be applied to material sampling of a sensitive position which is difficult to sample and analyze, such as a welding line or a heat influence region, and equipment and a pipeline without damage sampling conditions, and furthermore, the difficulty of estimating material performances of the in-service equipment is solved.

Description

technical field [0001] The invention belongs to the technical field of material engineering, and more specifically relates to a portable pneumatic grinding sampling device, which can efficiently and stably realize sampling from the surface of in-service equipment, and has the advantages of stable sampling process, small deformation, and low heat generation. Advantages such as no impact on organization. Background technique [0002] At present, with the rapid development of China's economy, the demand for energy is getting higher and higher, and the environmental pollution is also increasing. Therefore, improving energy utilization efficiency, developing new energy sources, and reducing harmful gases and greenhouse gas emissions have become economically sustainable. An important support point for development. While developing new energy sources, improving the operating parameters of industrial devices is the most effective means to improve the efficiency of existing energy u...
