When the vacuum degree of vacuum pump can not reach the requested degree, we usually use a vacuum gauge for testing. In fact, there are many reasons for the vacuum failure, but because of our single detection method, the vacuum gauge can only reflect the final pumping result of the system, but it...

Traditional rocket systems must carry large amounts of fuel to generate sufficient propulsion, while electric propulsion systems use electric fields to accelerate small particles to high speeds and emit them at very high speeds from the propeller. This high discharge speed greatly reduces the amo...

Vacuum grouting is a grouting process in which a vacuum pump is used to vacuum the outside of the plaster mold, or the reinforced plaster mold is placed in a vacuum chamber for negative pressure operation. Vacuum grouting reduces the formation time of the blank by increasing the pressure differen...
