Artificial contamination immersion experiment sample contaminating machine

Abstract

The invention discloses an artificial contamination immersion experiment sample contaminating machine. The artificial contamination immersion experiment sample contaminating machine comprises a contaminating machine host, wherein a detachable contaminating liquid tank is formed in the contaminating machine host; a net bag is arranged in the contaminating liquid tank; a pump is arranged on one sideof the contaminating machine host; a backup contaminating liquid column is arranged on the pump; a rotary faucet is movably arranged on the contaminating liquid column; a lifter is arranged on one side, opposite to the pump, of the contaminating machine host; the lifter is connected with the net bag through a guide rod; a sample processing table is arranged on the other side of the contaminatingmachine host; the contaminating machine host is further provided with a stirring device and a control device; and the pump, the lifter, the sample processing table and the stirring device are all connected with the control device. The artificial contamination immersion experiment sample contaminating machine is simple and convenient to operate, sample contaminating is carried out through the constant-speed lifting net bag, and the contaminating liquid can be added into the device at any time, so that the problems of poor sample uniformity and consistency, difficulty in stirring, sample difference and inaccurate experimental result caused by the loss of contaminating liquid are effectively solved.

Description

technical field [0001] The invention belongs to the technical field of decontamination machines, and in particular relates to a decontamination machine for artificial dipping experimental samples. Background technique [0002] In scientific research experiments, it is often necessary to explore the influence of specific substances such as dirt or paint on the sample material when it is covered on the surface of the sample material. For example, in the test of the electrical properties of high-voltage insulating materials, it is often necessary to artificially pollute and fully wet the surface of the insulating material sample, and apply a high voltage to the test sample to test the electrical properties of the material after contamination. In the national standard DLT859-2004 "Artificial Pollution Test of Composite Insulators Used in High-Voltage AC Systems", the dipping method (dipping method) is recommended as a basic method for sample contamination. The specific operating...
