Vacuum coating small and large vacuum pump
Small vacuum pump, small size, low noise, low power consumption, easy to operate, easy to carry, maintenance-free, continuous operation for 24 hours, and also allows the medium to be rich in water vapor.The most important thing is that because it is dry and oil-free, vacuum pump oil is not needed, so it will not pollute the working medium, and will not interfere with the analysis of the medium.

Features of large vacuum pumps:
Simply put: high power, high ultimate vacuum (absolute pressure is very small) (the smaller the absolute pressure, the higher the ultimate vacuum), and some can even do 10 negative square Pa, very close to the theoretical vacuum. The pumping rate is large, usually in units of "L/S (liters per second)". There are a wide range of applications in the industry.

Disadvantages: high price, large size, heavy weight, high noise, high energy consumption, need regular maintenance, not easy to move. Some large vacuum pump oil must be used, the work will produce oil mist, pollution of the working medium ...... these shortcomings in some games together is particularly evident, such as a large vacuum pump, although high vacuum, low vacuum but instead of wasting occasions, like In the laboratory, when a small amount of gas is required for gas sampling, gas analysis, gas circulation, vacuum adsorption, gas transfer, pressurization, indirect water absorption, drainage, etc., a large vacuum pump exposes many of its disadvantages. At this time, a small vacuum pump is used, and the rough vacuum (lower vacuum) can be satisfied, and the volume is small, the noise is low, the power consumption is small, the operation is easy, the port is easy to carry, the maintenance is free, the battery can be continuously operated for 24 hours, and the medium is rich in water vapor. . The most important thing is that because it is dry and oil-free, vacuum pump oil is not needed, so it will not pollute the working medium, and will not interfere with the analysis of the medium. And the price is relatively cheaper.

Small and large vacuum pump
Now, with the wide application of small vacuum pumps in various fields and the improvement of vacuum technology, the performance of small vacuum pumps is also increasing. For example, there is a high vacuum and small vacuum pump. The ultimate vacuum of Chengcheng Electromechanical can even be achieved, that is, negative pressure. About -0.09Mpa; pumping rate up to: 28L / Min; there is a small vacuum pump that can simultaneously pump and pump air, negative pressure (-50KPa), maximum output positive pressure (relative atmospheric pressure) 100KPa (about 1 kg ).
