[0002] In the production of refractory materials, it is necessary to measure the apparent pore density of refractory materials in batches. When using the apparent pore measuring instrument for testing, it is necessary to use a matching vacuum pump to extract air from the vacuum box where the product to be tested is placed. Due to the high humidity in the air, the vacuum box is equipped with a moisture absorption function. However, in actual use, it is found that after long-term use, the equipped vacuum pump has a decreased moisture absorption function, and moisture is absorbed into the vacuum pump, causing the vacuum oil to emulsify quickly, resulting in waste of vacuum oil and inaccurate test results. Due to the large production volume of products, vacuum is used frequently and frequently, and other functions of the vacuum pump can meet the needs of use. Replacing a new vacuum pump is expensive, resulting in unnecessary waste. Utility Model Content
