Filter black plastic leak hunting device

Abstract

The invention provides a filter black plastic leak hunting device. The device comprises a frame, a first positioning device, a second positioning device, a third positioning device, a fuel tank and an oil pump. Through setting a positioning bench, a filter black plastic is supported. Through setting the first positioning device, the second positioning device and the third positioning device, the filter black plastic is positioned and fixed so that the filter black plastic keeps stable. A first outlet of the first positioning device and a second outlet of the second positioning device are connected to two side joints of the filter black plastic. Through an oil inlet of the oil pump, the fuel tank is connected and oil is filled into a first joint through a first connecting pipe. The oil enters into the filter black plastic from the first outlet, then enters into a second channel from the second outlet and finally returns to the fuel tank from a second connecting pipe. Through observing whether the filter black plastic generates an oil leakage phenomenon, whether gas tightness performance is good is determined. In the invention, detection is accurate, the structure is simple and usage is convenient.

Description

technical field [0001] The invention relates to the technical field of leak detection, in particular to a filter black plastic leak detection device. Background technique [0002] Leak detection is mainly a non-destructive testing method to check whether there is a leak in the pressure vessel under test through the detection medium (gas or liquid), and to measure the size of the leak according to the detection medium, and to quantify and locate the defect. In order to ensure the airtightness and reliability of the filter black plastic, leak detection is required after the filter black plastic is processed. At present, the leak detection of the filter black plastic needs to be clamped first. , fixed, and then feed oil into the black plastic of the filter and observe whether the black plastic of the filter leaks oil to determine whether its airtightness is good. Because the black plastic structure of the filter is relatively special, the whole process is inconvenient to clamp...

AI Technical Summary

Problems solved by technology

Due to the special black plastic structure of the filter, it is inconvenient to clamp during the whole process, the labor intensity is high, and the work efficiency is low.
