Large vacuum pump and small vacuum pump

With the rapid development of China’s economy, the demand for vacuum pumps in industry and other fields is also growing. Faced with the fierce competition in the vacuum pump market, how should users choose the products they need? What is the difference between large vacuum pumps and small vacuum pumps?

Simply speaking, large vacuum pumps have high power, high limit vacuum (absolute pressure is very small) (the smaller absolute pressure, the higher the limit vacuum degree), and some can even achieve 10 negative power Pa, which is very close to the theoretical vacuum. The pumping rate is high, usually using “L/S (L / sec)” as the unit. There is a wide range of applications in industry.

But the price is high, the volume is large, the weight is large, the noise is high, the energy consumption is high, needs the regular maintenance, is not easy to move and so on. Some large vacuum pumps must use vacuum pump oil or lubricating oil. Oil mist will occur in their work. The above shortcomings are particularly obvious in some cases. For example, although large vacuum pumps have high vacuum, they are wasted in low vacuum situations. For example, in laboratories, only a small amount of gas needs to be sampled and sampled by pumps. In volume analysis, gas circulation, vacuum adsorption, gas transfer, pressurization, indirect water absorption, drainage and so on, the use of large vacuum pumps exposes its many shortcomings. At this time, with a small vacuum pump, the rough vacuum (low vacuum) can be satisfied, and compact size, low noise, low power consumption, easy to operate, easy to carry, maintenance-free, 24-hour continuous operation, but also allows the medium rich in water vapor. Most importantly, because it is dry, oil-free, no need for vacuum pump oil, so it will not pollute the working medium, will not interfere with the analysis of the medium and so on.

Small vacuum pumps are compact, low noise, low power consumption, easy to operate, easy to carry, maintenance-free, 24-hour continuous operation, and allow medium rich in water vapor. Most importantly, because it is dry and oil-free, it does not need vacuum pump oil or lubricating oil, so it will not pollute the working medium, will not interfere with the analysis of the medium and so on.

With the wide application of small vacuum pumps in various fields and the improvement of vacuum technology, the performance of small vacuum pumps has been constantly improved. For example, the limit vacuum of a small vacuum pump with high negative pressure can even be reached, i.e. negative pressure is about – 0.09 Mpa; the maximum pumping rate can be as high as 28L/Min; and it can also be used for both pumping and pumping. Small vacuum pump, negative pressure (-50KPa), maximum output positive pressure (relative atmospheric pressure) 100KPa (about 1 kg).

Therefore, with the rapid development of science and technology and the continuous improvement of production level, the performance of small vacuum pumps has been greatly improved. In some cases, small vacuum pumps can replace large vacuum pumps. This change is not only the progress of the vacuum pump industry, but also a good news for improving the productivity of the whole industry.
