Except for a few related people, most people don't understand many of the reasons, even if we have a large number of customers, they can't understand a lot of knowledge about the product. Sharing the relevant knowledge of submersible sand pumps on a regular basis hopes to be helpful for those who are interested in this industry. Below is the knowledge of electric drive of submersible sand pumps.
Underwater constant-speed AC power transmission devices for submersible sand pumps are practical. They are as productive as liquid-filled motors and closed box air-cooled motors. For liquid-filled submersible sand pump motors, the cooling oil or cooling water is in the motor. Circulation. If necessary, it can also be cooled by a heat exchanger. For closed box motors, air cooling is usually used. Wind is installed on the protruding part of the engine shaft. Air is circulated in the fins in the box, so that The ineffective heat in the submersible sand pump is dissipated into the surrounding water through the casing of the tank.
