Abstract
Embodiments include an apparatus and techniques for operating an electromagnetic cartridge seal. Embodiments include operating a cartridge seal in one of a plurality of modes, and receiving a signal at a force applying mechanism of the cartridge seal, the force applying mechanism being coupled to a primary sealing component of the cartridge seal. Embodiments also include controlling the force applying mechanism based at least in part on the received signal.
Claims16
A method for operating an electromagnetic cartridge seal, the method comprises:
- operating a cartridge seal in one of a plurality of modes, wherein the plurality of modes includes a dry mode and a wet mode, wherein the cartridge seal is filled with a fluid when operating in the wet mode, wherein the cartridge seal does not have fluid present when operating in the dry mode;
- receiving a signal at a force applying mechanism of the cartridge seal, the force applying mechanism being coupled to a primary sealing component of the cartridge seal, wherein the force applying mechanism is an electromagnet;
- switching between the plurality of modes;
- and
- controlling the force applying mechanism based at least in part on the received signal, wherein the force applying mechanism makes contact with the primary sealing component when operating the cartridge seal in the wet mode.
A system for operating an electromagnetic cartridge seal, the system comprises:
- a rotor;
- a primary sealing component coupled to the rotor, wherein the primary sealing component rotates with the rotor;
- and
- a force applying mechanism coupled to the primary sealing component and a housing of the electromagnetic cartridge seal, wherein the force applying mechanism is an electromagnet;
- wherein the cartridge seal is configured to switch between the plurality of modes, wherein the plurality of modes includes a dry mode and a wet mode, wherein the cartridge seal is filled with a fluid when operating in the wet mode, wherein the cartridge seal does not have fluid present when operating in the dry mode, wherein the force applying mechanism makes contact with the primary sealing component when operating the cartridge seal in the wet mode.
