High vacuum diffusion pump oil: the secret of extending the life of diffusion pump
In modern industry, high vacuum diffusion pumps are favored for their efficient pumping capacity and wide range of applications. However, how to ensure the long-term stable operation of the diffusion pump and extend its service life has been the focus of engineers and technicians. Among them, the choice and use of diffusion pump oil undoubtedly plays a crucial role.
First, we need to understand the importance of high vacuum diffusion pump oil. Diffusion pump oil is not only the core working medium of diffusion pump, but also the key to maintain high vacuum and stable performance. The high quality diffusion pump oil can ensure that the inside of the pump body is clean and smooth, reducing friction and wear, thereby reducing the failure rate and maintenance costs of the pump.
So, how to choose the right diffusion pump oil? The answer is simple: use the pump oil recommended by the manufacturer. This is because the design and manufacture of diffusion pumps are based on specific oil products, and the use of non-original oil products may cause the performance of the pump to decline, and even cause serious failures. The original pump oil has undergone strict quality control and testing to ensure the best match with the diffusion pump and long-term stable operation.
Next, we talk about the use of diffusion pump oil secrets. First, ensure that the cooling water of the diffusion pump is unimpeded before heating and during operation. This is because the diffusion pump will produce a lot of heat when working, if the cooling water is not smooth, it will cause the pump temperature to be too high, thus affecting the performance and life of the pump oil. At the same time, after stopping the heating, it must be ensured that the pump oil has been completely cooled before the cooling water can be turned off to prevent damage to the pump oil due to temperature changes.
Secondly, it is important to maintain the vacuum inside the diffusion pump. When the diffusion pump stops working, it should be ensured that the vacuum in the pump is maintained to avoid the oxidation of the pump oil caused by contact with the atmosphere. This is because oxidation will reduce the performance of the pump oil and shorten its service life. In addition, the pumped gas should be kept dry, corrosion-free, and dust-free to reduce damage to the pump oil and pump body.
In the use of diffusion pump oil, we also need to pay close attention to the oil level and the color of the oil. The oil level should be kept within an appropriate range to avoid too high or too low affecting the performance of the pump. At the same time, the color of the oil should be colorless or highly transparent reddish-brown, when the color of the oil becomes dark and black, the new pump oil should be replaced in time.
In addition, regular cleaning of the diffusion pump is also an important measure to extend its life. If a large amount of dust or particulate matter is produced during the process, these substances will form deposits in the pump oil, affecting the performance of the pump. Therefore, during each oil change, the inside of the diffusion pump should be thoroughly cleaned to remove sediment and ensure that the pump body is clean and smooth.
Finally, we would like to emphasize the importance of temperature protection switches. Many diffusion pumps are equipped with temperature protection switches, when the pump body temperature is abnormal, it can send a signal in time and cut off the power supply to the heater. Therefore, when designing the control system, it is necessary to connect the temperature protection switch to the system and interlock with the power supply of the diffusion pump heater to ensure the safe operation of the diffusion pump.
In summary, choosing the right diffusion pump oil, keeping the cooling water smooth, maintaining the vacuum state in the pump, paying attention to the oil level and the color of the oil, regularly cleaning the diffusion pump, and correctly using the temperature protection switch are all measures to extend the life of the high vacuum diffusion pump. As long as we master these secrets and put them into practice, we can ensure the long-term stable operation and efficient performance of the diffusion pump.
