In order to ensure safe and stable operation of the submersible motor, we will add pre-fill fluid to the submersible motor, then what is the role of submersible motor pre-filling?
Submersible motor pre-fill fluid has three roles: cooling, antifreeze, lubrication.
In order to prevent the submerged motor due to overheating and burn, in the submersible motor to add pre-fill fluid can play a cooling role in the winter weather cold submersible motor internal pre-filled liquid has played the role of antifreeze, so the submersible motor will not Because it is too cold and can not be normal operation; there also a role of the internal pre-filling fluid addition is to ensure lubrication, to prevent wear and tear.
