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 pressure switch will energize the pump if hydraulic pressure falls below a preset level and de-energize the pump when pressure returns to normal. A duty cycle of 3 minutes on and a cooling period of 20 minutes off is required to avoid overheating the pump motor.
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.
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.
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 ...
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]
Submersible pumps are mounted on two vertical guide rails and seal onto a permanently fixed "duckfoot", which forms both a mount and also a vertical bend for the discharge pipe. For maintenance or replacement, submersible pumps are raised by a chain off of the duckfoot and up the two guide rails to the maintenance (normally ground) level.
A drawback to the bellows thermostat was that it was also sensitive to pressure changes, thus could sometimes be forced shut again by pressure, leading to overheating. [6] The later wax pellet type has a negligible change in its external volume, thus is insensitive to pressure changes. [6] It is otherwise identical in operation to the earlier type.
