What is the dry running protector of screw pump? What's the principle and function? Thank you
When the temperature reaches a certain value, the signal is transmitted to the electric control box through a dry running protector, and the electric control box is used to stop the screw pump so as to protect the screw pump.
Principles are generally temperature sensing, such as: when the screw pump by air, the stator and rotor will be heated due to friction,
The utility model relates to a screw pump dry running protector, which is used for protecting the stator and the rotor of the screw pump from being transported by air
