Product description
The basic function of protector is to guarantee the seal of motor drive shaft so as to prevent well liquid invading motor inner chamber; balance the pressure of motor inner chamber and well annulus; bear axial force of the pump. There are 2 to 4 settlement chambers for most commonly used settlement protector. Capsule protectors can not only isolate well liquid directly by preventing well liquid into the motor to maintain the electrical motor oil clean, but also accommodates the expansion and contraction of the motor oil. The multistage mechanical seal between the protector and the electrical motor can prevent well liquid seeping into motor along the direction of axis.
