13, the biggest allow vapor entrance intensity of pressure
The biggest allowing unit of vapor entrance intensity of pressure is Pa. It is to point to fall in normal ambient conditions, the highest entrance intensity of pressure that the vapor that divide can take when the pump that enrage a town is working continuously. 2, working principle
Take the system to 10-2Pa to diffuse by rotational vavuum pump first pump oil is heated to boil, the point of bubble of ball of side arm bent housing that sheds to bring element of the gas inside the system pump ceaselessly from ejective oily vapour with high speed builds up, the working range that treats aeriform density to achieve mechanical vavuum pump and be taken out, obtain high vacuum gradually thereby.
