An organic heat carrier boiler is a new type of thermal energy equipment that uses thermal oil as the circulating medium for heating, and it is now widely used in industries such as textiles, dyeing and printing, and building materials. Thermal oil can be divided into synthetic oil and mineral oil, and under almost atmospheric pressure conditions, it can achieve high operating temperatures. This can significantly reduce the operating pressure and safety requirements of high-temperature heating systems, thereby enhancing the reliability of the system and equipment. Can different types of thermal oil be mixed?

Some businesses replace or add a portion of thermal oil after one or two years of boiler operation, but the newly added oil differs significantly from the original in terms of brand and performance, greatly shortening the lifespan of the thermal oil. Thermal oil cannot be mixed; if not replaced promptly, carbon deposits from the oil will accumulate at the bottom of the boiler drum, causing overheating and bulging, or adhere to the tube walls, leading to overheating and pipe bursts, posing serious safety hazards.

During the process of using lubricants, it's crucial to be familiar with identifying methods for transforming lubricants. Some bulk oil products can go bad due to improper storage. Therefore, this adds an extra layer of safety for peace of mind when using lubricants.

One, Oil Flow Observation Method: Take two measuring cups. Place one empty on the table and fill the other with the lubricating oil to be inspected. Hold the full cup high above the table, about 30-40 cm, and tilt it so that the lubricating oil slowly drips into the empty cup. Observe the flow pattern. High-quality lubricating oil will have a thin, even, and continuous flow; if the flow rate is inconsistent, with occasional large drops, it indicates that the lubricant has deteriorated.

Step 2: Method of Hand Rubbing: Rub the lubricant between the thumb and forefinger, repeatedly grinding it. If the lubricant contains too much impurities, it indicates that the lubricant lacks good lubrication, has excessive wear particles, and excessive friction. If there is a noticeable sandpaper-like friction between the fingers, it should no longer be used, and new lubricant should be replaced.

III. Illumination Method: On days with clear weather, hold the lubricant at a 45-degree angle to the horizontal surface using a screwdriver. Observe the oil droplets against the sunlight. Under illumination, a clear absence of metal shavings indicates good quality; if there are excessive shavings, a replacement is recommended.

Four: Oil Drop Stain Method: Take a clean red filter test paper. After the lubricant has leaked, drop a few drops of oil onto it. If there is black powder on the surface and it feels gritty when touched, it indicates that there are many impurities in the lubricant. Good lubricant has no powder, feels dry and smooth to the touch, and leaves a yellow stain.
