摘要:
A vacuum unit (11), a vacuum cleaning system (1) and a method for controlling a vacuum unit (11) is presented. The vacuum unit (11) comprises a compressor suction pump (30), an air valve (36) arranged at the inlet (40) of the compressor suction pump (30), at least one temperature sensor (32, 33) for sensing the temperature of air flowing through the compressor suction pump (30). A control unit (34) is configured to selectively open the air valve (36) in response to the temperature, wherein surrounding air is admitted into the inlet. The vacuum cleaning system (1) comprises the vacuum unit (11), a filtering system (12), and a pipe system (13) provided with a suction nozzle (14). The method includes creating (102) a first air stream, transferring dust and particles by means of the first air stream through the pipe system, measuring (104) the temperature of the air at the vacuum unit (11), and selectively opening (106) the air valve (36) in response to the temperature, so as to cool the first air stream.

A vacuum pump is provided, which suppresses occurrence of a gas product in an exhaust side outlet of a thread groove and maintains pump performance over a long period. The vacuum pump includes inflow suppressing walls formed by widening greater an exhaust side end portion of ridge portions, extended along a gas exhaust direction on an outer circumferential surface of an inner circumference side stator, forward in a rotor rotating direction than an intake side end portion, the inflow suppressing walls suppressing retention of gas in exhaust side outlets of thread grooves engraved among the ridge portions.

Die Erfindung betrifft eine Anordnung mit einer Vakuumpumpe (1) und ein Flutverfahren. Um das Fluten an den Prozess anzupassen, wird vorgeschlagen, einen Flutparameter (8) aus einer Menge von Flutparametern auszuwählen. Die Anordnung umfasst vorschlagsgemäß einen Flutparameterspeicher (7) und ein Flutparameterwählmittel (6).
摘要:
The present invention provides a stator disk including a connection hole for improving exhaust efficiency in a vacuum pump including a Seigbahn type molecular pump portion, and a vacuum pump including the stator disk. The vacuum pump according to an embodiment of the present invention includes a Seigbahn type molecular pump portion and includes, in a stator disk disposed therein, a connection hole that connects an upper space (an inlet port side region, an upstream side region) with a lower space (an outlet port side region, a downstream side region) in the axial direction of the stator disk.
