Adaptor and vacuum pump

Provided are a vacuum pump and an adapter used in the vacuum pump that are capable of responding to various changes in specifications at low cost. A turbo-molecular pump includes a base, a stator blade that is provided above the base in an axial direction of a rotor, a rotor... Edwards Japan Limited

Abatement device

Provided is an abatement device that reduces an amount of drainage of circulating water. The abatement device lowers an average drainage flow of circulating water to a low flow, when a ratio of a concentration of silicon dioxide within the circulating water and a concentration of hydrogen fluoride within the... Edwards Japan Limited

Vacuum pump

Provided is a vacuum pump having a stator disc having a divided structure, in which gaps or misalignments that occur between connection surfaces at which the divided structure is connected are reduced. In a turbo-molecular pump according to this embodiment, a mating relationship between a stator disc and a stator... Edwards Japan Limited

Vacuum pump control device and vacuum pump

An object of the present invention is to improve, using a simple configuration, heat dissipation of a regenerative resistor that is disposed in a vacuum pump control device (controller) connected to a vacuum pump. The regenerative resistor disposed in the vacuum pump control device is stored in an aluminum die-cast... Edwards Japan Limited

Vacuum pump and abnormality cause estimating vacuum pump

Provided are a vacuum pump and a method for the vacuum pump in which, when contact between a rotating body and a stator is sensed, the cause of the contact can be analyzed. Contact determination is made using a threshold for rotating body contact determination for a displacement signal and... Edwards Japan Limited

Dry pump and exhaust gas treatment method

An object of the present invention is to provide a dry pump and an exhaust gas treatment method which can improve an effect of inhibiting a reaction product from adhering to the inside of a gas outlet port of the dry pump, a gas exhaust pipe, or the like and... Edwards Japan Limited

Outlet port part and vacuum pump

An outlet port part has a heat insulating portion for preventing heat obtained from a heater disposed in the outlet port part from being transmitted toward a base side, and for transmitting the heat efficiently to the back (the vacuum pump side) of the outlet port. The heat insulating portion... Edwards Japan Limited

Vacuum pump

To provide a vacuum pump capable of heating only a flow channel extending from the vicinity of an exit of a thread groove exhaust flow channel toward an outlet port and prevents the accumulation of a product that is caused by a decrease in the temperature of process gas near...
