    摘要: A system and method for rapid pressurization of a motor compartment and cooling system during a shutdown, a surge, and/or other situations in which the suction pressure significantly varies. A motor/compressor arrangement includes a seal gas system fluidly communicating with the motor compartment via a motor pressurization line, with the outlet of the compressor, and with a shaft seal. A motor pressurization valve is coupled to the motor pressurization line and a controller is configured to open the motor pressurization valve at start-up of the motor-compressor to supply seal gas to the motor compartment and to pressurize the motor compartment when a difference between the seal gas supply pressure and the suction pressure is indicative of the seal gas supply pressure being insufficient.

    摘要: The invention provides a stator-side member which is arranged in a vacuum pump and which, without the provision of a heat insulation material, prevents the deposition of products at the lower side of a threaded groove pump unit, with this lower side being an area of high pressure where the deposition of products (deposits) occurs easily, and also provides a vacuum pump equipped with this stator-side member. A threaded groove spacer configured to have a coefficient of thermal conductivity lower than a predetermined value is arranged in a vacuum pump equipped with a threaded groove pump unit. (1) The threaded groove spacer is manufactured from a material having a coefficient of thermal conductivity lower than that of a member which opposes or comes into contact with the threaded groove spacer. Specifically, this material has a coefficient of thermal conductivity lower than that of aluminum or aluminum alloy, and is preferably any one of stainless steel, fiber-reinforced plastic, polyetherimide, and polyetheretherketone. (2) The threaded groove spacer is constituted by at least two or more parts.
