How long should a vacuum pump last?

With the development of the times, many kinds of vacuum pumps have been developed, and their pumping speed ranges from a few liters per second to hundreds of thousands or millions of liters per second. Modern enterprises also have higher and higher requirements for vacuum pumps, which makes the market system of vacuum pumps more and more complete. In this article, we will make a brief inventory of the basic information about vacuum pumps, such as the working hours and working characteristics of vacuum pumps.

How long can the vacuum pump work?

Vacuum pumps can run for long periods of time, usually for several hours of continuous operation without problems. We have designed the vacuum pump with long time operation in mind. At the same time, the operating cost of the vacuum pump is not high, because its structure is simple, manufacturing precision requirements are not high, easy to process. It is worth noting that when the vacuum pump runs for a long time, it is necessary to pay attention to the cleanliness of the pump oil, for example, the pump oil contains water or has debris to change the oil in time to avoid equipment failure.

How to choose a vacuum pump?

Choosing a vacuum pump is not a simple job, we need to consider the working characteristics of the vacuum pump, the use scenario and the type, first of all, to choose the working point of the vacuum pump correctly, because each pump has a certain range of working pressure. At the same time, judge the requirements of vacuum equipment for oil pollution. If the equipment strictly requires oil-free, you should choose various oil-free pumps. In addition, the vacuum pump should be able to discharge the whole amount of gas produced in the process of vacuum equipment under its working pressure.

In a word, the function of a single stage vacuum pump is to remove gas molecules from the vacuum chamber and reduce the gas pressure inside the chamber to achieve the required vacuum level. Therefore, the above factors are carefully considered in order to achieve the process index, work efficiency and equipment working life requirements of different products.

Is there a downside to vacuum pumps?

·Low vacuum level

Although the vacuum pump has the advantages of compact structure, high efficiency and durability. But there are still some disadvantages when using vacuum pump, take water ring pump as an example. Its vacuum degree is low, not only because of the structural limitation, but more importantly, it is limited by the saturated vapor pressure of working fluid. With water as working fluid, the ultimate pressure can only reach 2000~4000 Pa. With oil as working fluid, it can reach 130 Pa.

·Restriction of use

There are certain restrictions on the use of vacuum pumps, for example, they cannot pump media with granularity and are insoluble in water. However, vacuum pumps are generally uniform in suction, smooth and reliable, simple to operate and easy to maintain, which can help you achieve good efficiency in food, textile, pharmaceutical, chemical and other fields.
