With the continuous development of the times, vacuum pumps are used more and more in all walks of life, and once the vacuum pump is running, it rarely stops, so some problems may arise. The most common one is the vacuum pump. Smoke comes out of the exhaust port. What happens when smoke comes out of the exhaust port of a vacuum pump? How to solve it?

1. Use a poor quality vacuum pump oil mist filter (exhaust filter element/exhaust filter). The function of the vacuum pump's oil mist filter (exhaust filter element/exhaust filter) is to filter the oil mist particles in the gas exhausted by the vacuum pump through multiple layers of high-quality vacuum pump filter cotton, and finally filter the oil mist particles in the gas exhausted by the vacuum pump. It is adsorbed on the oil mist filter, accumulates continuously, and then gathers into vacuum pump oil droplets and drips back to the oil tank of the vacuum pump, and finally flows back into the vacuum pump through the oil return pipe. Faced with this situation, you can replace the oil mist separator (exhaust filter element/exhaust filter) with better quality

2. The exhaust filter is not installed correctly. There are two types of vacuum pump exhaust filters, one with a screw and the other without a screw. The installation of the exhaust filter with a screw is generally done by aligning the screw hole reserved on the vacuum pump oil tank and screwing it on. Then you need to use the vacuum pump filter element shrapnel to lock the exhaust filter element. At the same time, pay attention to aligning the vacuum pump. exhaust port. For those without nuts, you need to align it with the exhaust port of the vacuum pump, lock the carbon filter element, and align it with the exhaust port of the vacuum pump.

3. There is foreign matter in the one-way oil return valve or float valve. The function of the one-way oil return valve and the float valve is to return the vacuum pump oil stored in the oil tank where the vacuum pump exhaust filter element is located to the vacuum pump cavity. If there is foreign matter in the one-way oil return valve or the float valve, it will block the return flow of the vacuum pump oil, causing Problems such as white mist and oil injection from the vacuum pump. Faced with such a problem, you need to check whether there is any foreign matter in the one-way oil return valve or float valve, and if so, remove it in time.

4. The quality of vacuum pump oil. The quality of vacuum pump oil can also cause the problem of smoke from the vacuum pump. For this reason, if you want the vacuum pump to operate normally, you still need to choose good quality vacuum pump oil.
