Plasma surface treatment equipment for the use of bottled compressed gas introduction:

Compressed gas is a key component of industrialization. The compressed air commonly used in industrial production includes air compression and bottled compressed gas. Air compression is called the second power plant, only secondary to power engineering, it is also a multifunctional processing process gas; Industrial grade bottled gas is generally packaged in controllable gas bottles, the standard pressure is 13-15MPa, with the advantages of saving indoor space, safety and conducive to transportation. The compressed gas will be based on the application of specific working pressure reduction and stable working pressure, so how should the pressure of the gas of the plasma cleaner be regulated?

Gas pressure control is one of the key factors to ensure the normal operation of plasma cleaning machine. Gas cylinder decompresser is a kind of equipment that changes the high pressure vapor body into the low pressure vapor body in the gas. The processing process vapor body applied by cleaning equipment is mainly the high pressure vapor body of the bottle, so as to ensure the reliability of various processing techniques and operation reliability. Generally, according to the use, the high pressure vapor body will be reduced to 0.2-0.4Mpa. In the application, it is necessary to ensure the tightness of the connection between the cylinder and the pressure reducer. The raw material belt is used as the sealing medium, and the thread of the cylinder mouth is wrapped when the reducer is installed on the cylinder. It is proposed to choose 3/8 interface to replace the original vertical connecting head, and choose the quick torsion connecting head or double jacket connecting head to ensure the tightness between the steam output pipe and the plasma cleaning machine.

If the chemical gas is argon, it is suggested to decompress with oxygen. The reason is that the output working pressure of the argon gas decompressor is generally 0.15MPa. For example, if a bottle of gas is supplied to several cleaning machines, the output working pressure cannot be met, which is very easy to cause the working pressure alarm of the machine and equipment. Pneumatic pressure regulating valve is the key component of pneumatic control, its role is to manipulate the external vapor body in the required pressure, to ensure that its working pressure and flow stable. Whether it is vacuum plasma cleaning equipment or atmospheric pressure equipment input gas need to install pressure regulating valve, in order to ensure the cleanliness of the vapor body in the application.


In order to facilitate the observation of air pressure, a barometer or a pressure regulating valve with a barometer should be installed on the pressure regulating valve. If you want to show an underpressure protection alarm, you can also select an alarm barometer or add a pressure controller.

Pipeline throttle valves are commonly used in atmospheric plasma cleaning equipment, which can be used to adjust the size of the vent to achieve pressure and flow monitoring. The use of most of the fast fast plug joint, small volume. Atmospheric pressure plasma cleaning machine commonly used processing technology vapor body is a kind of clean compressed air, can also decide which kind of gas to use according to the effect of the treatment of products, the stability of the gas working pressure is far less than the vacuum cleaning machine. In addition, you can install a monitoring system if you want to view in real time.
