Patent number: 10208753Abstract: The speed of a cooling fan of a scroll pump is controlled such that fan-generated noise can be kept low. The scroll pump includes a pump head, a pump motor, the fan, a controller and one or more sensors. The pump head includes a plate scroll set in which a tip seal is provided to create a seal between the blade and the opposing plates of the plate scrolls of the set. The speed of the fan is cycled by the controller, and the power draw on the pump motor as a result is checked. These results are used to infer the state of the pump, i.e., to discriminate several different states of the pump from one another, including a state in which a new tip seal is being worn in, and to control the speed of the fan accordingly.Type: GrantFiled: May 24, 2013Date of Patent: February 19, 2019Assignee: Agilent Technologies, Inc.Inventors: Ronald J.
