Dry running protection, also known as dry-run protection or dry-running protection, is a type of protection mechanism to prevent a rotor, pump or stirrer shaft from operating without any medium added, as the bearing and shaft seal might be damaged if the motor is run while dry. [1]
Pleuger Industries was founded in 1929 by Friedrich Wilhelm Pleuger, when he invented glandless motor as a replacement to the borehole shaft and piston pumps. [12] [13] Since water was used to lubricate and cool the bearings of the wet rotor motor, the patent was regarded particularly ecologically benign and effective at the time.
When overheating, the temperature of the part rises above the operating temperature. Overheating can take place: if heat is produced in more than expected amount (such as in cases of short-circuits, or applying more voltage than rated), or; if heat dissipation is poor, so that normally produced waste heat does not drain away properly.
A motor capacitor which is a component of a hot tub circulating pump can overheat if defective. [9] This poses a fire hazard, and the U.S. Consumer Product Safety Commission (CPSC) has received more than 100 reports of incidents of overheating of the motor capacitor, with some fires started. [9]
Overheating of Li-ion cells and battery packs is an ongoing technological challenge for electrochemical energy conversion and storage, including in electric vehicles. Immersion cooling is a promising thermal management technique to address these challenges. [ 26 ]
A 0.75 HP bore-well submersible pump which had been used to pump groundwater One style of submersible pump for industrial use. Outlet pipe and electrical cable not connected. A submersible pump (or electric submersible pump (ESP) is a device which has a hermetically sealed motor close-coupled to the pump body. The whole assembly is submerged in ...
The Titan submersible was so deep, experts said, that the forces behind the "catastrophic implosion" would have been equivalent to the weight of Paris' Eiffel Tower. What is a 'catastrophic ...
A thermal fuse is used when the overheating is a result of a rare occurrence, such as failure requiring repair (which would also replace the fuse) or replacement at the end of service life. [1] One mechanism is a small meltable pellet that holds down a spring.
