Inner cleaning and airtightness detecting device for oil filling pipe, and method thereof

Abstract

The invention relates to an inner cleaning and airtightness detecting device for an oil filling pipe, and a method thereof. The method comprises the following steps: (1) fixing, namely respectively fixing the upper end and the lower end of the oil filling pipe with an upper clamping seat and a lower clamping seat; (2) cleaning, namely making a high-pressure jet head to an appropriate position for extending into the upper port of the oil filling pipe, then starting a high-pressure water pump for cleaning the inner part of the oil filling pipe, and after cleaning is finished, making the high-pressure jet head rise to an original position; (3) plugging, namely making a slide carriage frontwards move to an appropriate position so that an upper plugging head is aligned with the upper port of the oil filling pipe, then making the upper plugging head fall to an appropriate position for plugging the upper port of the oil filling pipe, and simultaneously making a lower plugging head perform oblique upward movement for plugging the lower port of the oil filling pipe; (4) inflating, namely starting an air pump and performing inflation on the inner part of the oil filling pipe through the lower plugging head; and (5) immersing, namely rotating a rotating board for 180 DEG so that the upper end of the oil filling pipe is arranged at the lower part, then making a sliding board fall for immersing the upper end of the oil filling pipe into a water tank. The inner cleaning and airtightness detecting device for the oil filling pipe and the method have advantages of novel design, compact structure, low production cost and high detecting efficiency.

Description

technical field [0001] The invention relates to an air tightness detection device and method for cleaning the inside of a filling pipe. Background technique [0002] The filling pipe is welded by multiple sections of metal pipes with different thicknesses. In order to prevent oil leakage from the filling pipe, an air tightness test must be carried out, and the inside of the filling pipe must be cleaned before the air tightness test. At present, the cleaning process and the air tightness testing process of the filling pipe are two independent processes, which are carried out on different machines and are carried out by two production personnel. The production line is too long, the equipment investment is high, and the labor cost is high. , Low production efficiency and other shortcomings. Contents of the invention [0003] In view of the deficiencies of the prior art, the technical problem to be solved by the present invention is to provide a novel design, compact structur...
