Key Points for Selecting a Vacuum Pump

Key Points for Selecting a Vacuum Pump

1. The ultimate pressure of the vacuum pump should meet the working pressure of the process. Typically, the ultimate pressure of the pump is chosen to be about an order of magnitude lower than the process requirements; 2. Each type of pump has a certain working pressure range; ...

Vacuum is not "empty"! Scientists may have discovered a fourth mode of heat transfer.

Vacuum is not "empty"! Scientists may have discovered a fourth mode of heat transfer.

We all know that there are three main modes of heat transfer in real life: convection, conduction, and radiation. In a vacuum, however, due to the absence of a medium, heat cannot be transferred.

When selecting and installing a vacuum gauge, the following considerations should be noted:

When selecting and installing a vacuum gauge, the following considerations should be noted:

1. Due to the potential pressure gradient in the vacuum chamber, it is important to choose the installation location appropriately. 2. The surface and sealing materials exhibit outgassing phenomena. Therefore, the pressure indicated by the vacuum gauge may be higher than the pressure in the vacuum chamber. The connecting flange should be as short as possible, and the number of seals should be minimized.

When selecting and installing a vacuum gauge, the following considerations should be noted:

Common Methods for Cleaning Vacuum Materials and Vacuum Systems

Common Methods for Cleaning Vacuum Materials and Vacuum Systems

In vacuum applications, vacuum systems and vacuum materials inevitably become contaminated by various factors such as dust, oxides, and grease. When these contaminants affect the operation of the vacuum system or the cleanliness of the vacuum materials, it becomes necessary to clean the vacuum system and vacuum materials. Here, we will discuss the common methods used for cleaning vacuum materials and vacuum systems.
