Embodiment

[0021] see figure 1 , the present invention provides a technical solution: the specific process steps of the method for testing nitrogen gas spring leakage are as follows:

[0022] Step 1: Prepare a container and add a certain amount of solution inside the container;

[0023] Step 2: Set a liftable fixture inside the container;

[0024] Step 3: Install and fix the nitrogen gas spring at the mouth of the container through a clamp;

[0025] Step 4: Move the nitrogen gas spring to the inside of the solution through the lifting fixture and squeeze the nitrogen gas spring;

[0026] Step 5: Observe whether there are bubbles in the solution. If there are bubbles, it means that the nitrogen spring is leaking. If there are no bubbles, it means that the nitrogen spring is not leaking;

[0027] The fixture is convenient to quickly lift up and down the inner wall of the container;

[0028] The length of the container is 0.8-1.2m, the width is 0.5-0.6m, and the height is 0.7-0.8m;

Abstract

The invention belongs to the technical field of nitrogen springs, and particularly relates to a method for testing gas leakage of a nitrogen spring, which comprises the following steps of: 1, preparing a container, and adding a certain amount of solution into the container; 2, arranging a clamp capable of ascending and descending in the container; 3, mounting and fixing a nitrogen spring at the opening of the container through a clamp; 4, moving the nitrogen spring into the solution through a lifting clamp, and extracting the nitrogen spring; and 5, observing whether bubbles are generated in the solution, if so, indicating that the nitrogen spring leaks gas, and if not, indicating that the nitrogen spring does not leak gas, so that whether the nitrogen spring leaks gas can be directly andquickly observed, the operation is convenient, and the detection precision is relatively accurate.

Description

technical field [0001] The invention relates to the technical field of nitrogen gas springs, in particular to a method for testing gas leakage of nitrogen gas springs. Background technique [0002] Nitrogen gas spring is a new type of elastic component with high-pressure nitrogen as the working medium. It has small size, large elasticity, long stroke, stable operation, precise manufacturing, long service life, gentle elastic curve, and no need for preloading, etc. It has Things that are difficult for conventional elastic components such as metal springs, rubber and air cushions. [0003] After the nitrogen gas spring is produced, its air tightness needs to be tested to ensure the quality, but the air tightness of the nitrogen gas spring cannot be directly observed by the naked eye, so it involves a method for testing the gas leak of the nitrogen gas spring. Contents of the invention [0004] The purpose of the present invention is to provide a method for testing nitrogen ...
