Steps for Solving the Air Extraction Phenomenon with a Planetary Reducer

During the use of planetary reducer, different Glitch may occur due to improper operation and other reasons. The specific problem we need to solve today is about the air extraction phenomenon that occurs during the use of planetary reducers. The occurrence of this phenomenon is not a major problem, so planetary gearbox users do not need to panic. If it occurs, we should solve it in a timely manner and calmly respond. The specific solution is analyzed by the Babman technical team for you:

1. For higher planetary reducers, direct exhaust to the atmosphere cannot be achieved. For example, direct exhaust to the atmosphere can cause a large pressure difference between the suction and exhaust ports of the planetary reducer, resulting in overload of the reducer. To ensure that a higher vacuum can be reached, it is necessary to ensure a clear space between the reducer rotors.

2. When using, it is necessary to have a front stage pump, which is used to suck the pressure in the system to a certain range before starting the planetary reducer. This can avoid overloading of the reducer. The front stage pump can choose vacuum pumps such as water ring vacuum pumps, rotary vane vacuum pumps, slide valve vacuum pumps, reciprocating vacuum pumps, etc. that can directly exhaust the atmosphere.

3. Due to the continuous rotation of the rotor of the precision servo planetary reducer, the sucked gas is sucked into the space between the rotor and the pump casing from the intake port, and then discharged through the exhaust port. Due to the fully closed space after suction, the gas in the pump chamber does not compress or expand. However, when the top of the rotor rotates past the edge of the exhaust port and the space is connected to the exhaust side, the gas pressure on the exhaust side is relatively high, A portion of the gas rushes back into space, causing a sudden increase in gas pressure. When the rotor continues to shift, gas is expelled from the pump.
