Definitions

  • the present invention relates to a vacuum pumping system.
  • the present invention concerns a vacuum pumping system of the kind comprising one or more vacuum pumping devices and a corresponding electronic control unit for controlling and monitoring the operation of said devices.
  • Vacuum pumping systems are known for instance from US 5,733,104 .
  • said pumping systems In case of high vacuum, i.e. in case of pressures in the range 10-4 to 10-8 mbars, said pumping systems generally comprise a turbomolecular vacuum pump associated with a backing pump or fore pump, for instance of mechanical type, allowing the turbomolecular pump to evacuate gas at atmospheric pressure.
  • turbomolecular pump An example of turbomolecular pump is disclosed in US 5,238,362 in the name of the present Applicant.
  • Both the turbomolecular pump and the fore pump need a local electronic control unit for controlling and monitoring the operation of the pump and of the accessory devices, if any, mounted on board or associated with the pumping device, such as for instance valves, pressure detectors, cooling systems etc.
  • said remote unit and the local electronic control unit of said pump are generally equipped with serial interfaces and they can be connected together by cables, permanently or only occasionally, when necessary.
  • EP 1,041,471 discloses a device for the remote control of a vacuum pump, in particular a turbomolecular pump equipped with magnetic suspensions, comprising a local control unit mounted on board the pump and a remote control unit, said units being arranged to communicate with each other thanks to a connection by means of an RS232 serial cable.
  • the remote control unit comprises a multiple interface capable of simultaneously communicating with the interfaces of all local control units in order to monitor and control the corresponding vacuum pumps.
  • a pumping system of the above type is disclosed for instance in US 5,971,711 , disclosing a system consisting of multiple pumps of different kinds (turbomolecular, mechanical, cryogenic...pumps), each having its own local control unit, connected through an RS232 serial cable with a corresponding communication gate of a single remote control unit.
  • US 5,696,495 discloses a system for controlling and regulating a construction installation having a plurality of components, said components being coupled through cables to a single control unit, which in turn communicates with a remote routing station through a communication network.
  • serial cables can be accidentally disconnected or damaged, with a consequent interruption of the communication between the remote control unit and the corresponding local control unit.
  • the vacuum pumps forming said system can thus be located in the most suitable positions and at greater mutual distances, without any limitation related to the use of wired connections.
  • a mobile and portable remote unit could be provided, instead of a fixed station as in the prior art.
  • the pumping system according to the invention can be advantageously built starting from conventional control units, since it will be sufficient to connect said control units (both the local units and the remote one) with corresponding wireless interface modules.
  • said vacuum pumping system 1 includes a high-vacuum pumping device 11 and a backing or fore pumping device 31.
  • Said pumping devices 11 and 31 are mutually connected through a vacuum line (not shown), so that the gas flow sucked from a chamber under high vacuum conditions by said high-vacuum pumping device 11 can be evacuated at atmospheric pressure through said backing pumping device 31.
  • Pumping device 11 is preferably equipped with a high vacuum pump 13, for instance a turbomolecular pump, and further comprises a local electronic control unit 15 for monitoring and controlling the operation parameters of said high vacuum pump 13, by driving the electric motor of said pump and other electromechanical devices that will be described hereinafter.
  • a high vacuum pump 13 for instance a turbomolecular pump
  • a local electronic control unit 15 for monitoring and controlling the operation parameters of said high vacuum pump 13, by driving the electric motor of said pump and other electromechanical devices that will be described hereinafter.
  • pumping device 31 is equipped with a fore pump 33, preferably a mechanical pump, for instance an oil pump, and includes a local electronic control unit 35
  • Said local electronic control units 15, 35 are preferably powered through the mains voltage, by means of corresponding power supply cables 17, 37.
  • Pumping device 11 is further equipped with a set of secondary apparatuses, which also can be controlled by said local control unit 15.
  • said apparatuses may comprise a pressure detector 19 for monitoring the residual pressure inside said pump, a cooling fan 21, a vent valve 23 controlling the admission of a gas for slowing down the pump during the stopping phase, a purge valve 25, controlling the admission of a dilution gas before discharging the pumped gas to the outside environment, when said pumped gas is a corrosive or harmful gas.
  • local control unit 35 can control the secondary apparatuses pumping device 31 is equipped with.
  • fore pump 33 is an oil mechanical pump
  • said apparatuses may comprise a pressure detector 39 for monitoring the residual pressure inside said pump, an oil detector 41 for monitoring the level and the temperature of the oil bath, a foreline valve 43 located in the vacuum line connecting high-vacuum pumping device 11 with backing pumping device 31.
  • Pumping system 1 further includes a single remote control station 51 including a remote control unit 53, usually equipped with or connected to an electronic processor, for central management and control of pumping system 1.
  • both said remote control unit 53 and said local control units 15, 35 of pumping devices 11, 31 must be equipped with interfaces for two-way communication of data and commands for controlling the pumping system operation.
  • each local control unit 15, 35 is equipped with a wireless communication module 27, 47 allowing said local control units 15, 35 to dialogue with a corresponding communication module 55, also of wireless type, connected with remote control unit 53.
  • Wireless communication module 55 of remote control unit 53 is chosen so that it can dialogue with wireless communication modules 27, 47 of each local control unit 15, 35.
  • Module 55 can be for instance a multi-channel communication module, communicating on each channel with the communication module of a different local control unit. That solution allows, among othet things, avoiding potentially disturbing crosstalk between the communication signals of contiguous pumping devices or of different pumping systems, equipped each with its control station and located close to one another.
  • the local control units of a plurality of pumps can be managed by means of a single remote control station 51, both when said pumps are connected together by a vacuum line and when they are mutually independent and are used for degassing different environments.
  • control station 51 and pumping devices 11, 31 controlled by the station can be eliminated, so that the only wired connections in pumping system 1 consist in power supply cables 17, 37, 57 of said pumping system and said control station, for connection to the mains.
  • control station 51 if it is not connected to the mains but is powered otherwise, for instance by means of batteries, can be built as a portable device instead of being a fixed station.
  • pumping system 1 does not require use of special control units, but it can be built by connecting conventional control units 15, 35, 53 with corresponding wireless communication modules 27, 47, 55, for instance through serial connections 29, 49, 59.
