With the rapid development of China's economy, the demand for vacuum pump in industry and other fields is growing. In the face of fierce competition in the vacuum pump market, how should users choose their products? What is the difference between large vacuum pump and micro vacuum pump. Central vacuum pump is here to answer your questions.
Characteristics of large vacuum pump
High power, high limit vacuum, but high price, large volume, heavy weight, high noise, high energy consumption, need regular maintenance, not easy to move. Some must use vacuum pump oil or lubricating oil, which will produce oil mist in work, but it will be wasted in low vacuum situation. For example, in the laboratory, only a small amount of gas needs to be sampled, analyzed, circulated, vacuum adsorbed, gas transferred, pressurized, indirectly absorbed water and drained by pump, many disadvantages of large vacuum pump have been exposed. So how to reduce these shortcomings is a very difficult job for professional staff, but it is still worth our expectation.
Characteristics of micro vacuum pump
Small size, low noise, low power consumption, easy to operate, easy to carry, maintenance free, 24-hour continuous operation, also allows the medium rich in water vapor. The most important thing is that it is dry and oil-free and does not need vacuum pump oil or lubricating oil, so it will not pollute the working medium and interfere with the analysis of medium. And the price is much cheaper.
With the wide application of small vacuum pump in various fields and the improvement of vacuum technology, the performance of small vacuum pump has also been improved. Now, with the rapid development of science and technology and the continuous improvement of production level, the performance of small vacuum pump has also been greatly improved. In some fields, small vacuum pump can replace large vacuum pump, such change is not only in vacuum pump industry It is also a good news for improving the productivity of the whole industry.
