when the filter element of vacuum pump appears pay attention to these signals

Vacuum pump is a kind of equipment that uses physical, chemical, or mechanical methods to extract air from containers to obtain different degrees of vacuum. With the continuous development of science and technology, the application field of vacuum pump has been widely used in many industries such as petrochemical industry, medicine and biology, new energy, plastic coating, etc.

In combination with the current economic development, natural environment and government trends, the vacuum pump filter has almost become the standard configuration of each vacuum pump in the call for “carbon neutrality”. In recent years, with the continuous growth of the gross national product, the environmental pollution emissions caused by the vacuum pump industry have not increased, but have decreased year by year. This is because, with the function of the vacuum pump filter produced by the manufacturer, the exhaust gas of the enterprise can meet the inspection standards of the National Environmental Protection Quality Inspection Bureau.

Since the vacuum pump filter is so important to the vacuum equipment, how do we know when the filter element needs to be replaced? Next, the vacuum pump manufacturer will introduce the following common signals for your reference!

1. When the pressure gauge reading of the vacuum equipment is abnormal (in the red area), there is a fault in the vacuum pump chamber, which may be that the oil mist separator has been blocked, and the filter element of the oil mist separator needs to be replaced in time.

2. Impurities such as black smoke, black fog, etc. appear at the exhaust port of vacuum pump:
a. The old oil-gas separator has been damaged and cannot work normally.
b: The filter element of the oil mist separator is blocked. The use of the oil mist separator has good oil repellency, so that the filter element can maintain low resistance for a long time, so it has a longer service life.

3. If the pressure gauge on the oil mist separator indicates too low, or the current consumption of the drive motor is less than that under normal conditions. The oil mist separator is damaged. At this time, the oil mist separator with high quality and long service life recognized by the market should be used.

Although the vacuum pump has a high price, it is a real “sick seedling”. While the precise equipment brings convenience to the enterprise, it also needs more careful and patient maintenance. The filter element of the vacuum pump is undoubtedly one of the important accessories for the vacuum pump. Ensuring the safe and stable operation of the inlet filter and exhaust filter of the vacuum pump is the key to reducing the cost of maintaining the vacuum pump for enterprises.
