Description

Welch Belt Drive vacuum pump model 1399B-10 giving you an ultimate vacuum of 0.001 Torr (1 micron) and a volumetric flow rate of 1.2 CFM. These belt driven rotary vane vacuum pumps are ruggedized and built to perform and last in demanding environments and applications. NOTE: NO Motor Present, you must purchase your own drive motor.

The Belt Driven Rotary Vane Pump has a high oil capacity which also yields a high contamination tolerance. Furthermore, the lower operational RPM, which is about 3 times less than a direct drive rotary vane pump, will result in a longer service life due to lower operational temperature (about 10 degrees less) and less wear and tear.

The trade-off are that these types of pumps are heavier than its direct drive rotary vane counterparts, require more oil, and have more moving parts such as wheel and pulley.

Force Decay Leak Testing Systems
Force Decay Leak Testing Systems are instruments that detect and quantify leaks in a test specimen through measuring the drop in force an inflated specimen applied onto a pressure transducer. The specimen is placed into a vacuum chamber, a vacuum is pulled, and the test sample inflates. As the test sample inflates, it applied a specific force onto the force transducer. This force is measured and recorded over time. If a leak exists, the specimen will deflate and lose pressure, as a result, the force it applies onto the force transducer will decrease. This in turn will enable for detection and quantification of a leak in the specimen.
Altitude Simulation Controller Instruments
An Altitude simulation Controller is type of vacuum controller that simulates a certain altitude because altitude can be derived from vacuum levels. An altitude simulation controller will enable you to hold your vacuum level at a certain altitude equivalent of testing, run an altitude vs time profile, or rate of change of altitude vs. time. Further options include a vacuum pump relay that will control when the vacuum pump turns on and a vacuum valve.
Our Work: Electronic Component Testing of Satellites at High Altitudes
Electronic Components of Satellites behave differently in outer space as compared to how these behave at sea level. How do you know that your satellite will survive outer space? How do you confirm that your circuit boards will function properly at higher altitudes? There is only one way to find out, and that is to test and validate your design.
Related Articles: Force Decay Leak Testing
Force Decay Leak Testing is a very popular quantitative leak testing method used to quality test package and product integrity due to its ability to detect small leaks which cannot be seen through visual inspection. In this method, the test specimen is internally inflated by either internal pressurization or vacuum force. The inflated test specimen will, in turn, apply a force on a pressure transducer. Finally, the change in force applied by the inflated specimen over a specified time is observed.
