From a thermodynamic point of view, the driving force for the precipitation of gold and silver from the CN-containing solution can be quantitatively expressed by the reduction potential. which is
Therefore, strong oxidants are required. Its oxidizing ability depends not only on the redox potential but also on the pH and ion concentration and temperature. It is easier to understand how their behavior and relationship in the redox system are represented by the oxidation-reduction potential E-pH diagram. Fig. 1 is an E-pH diagram of Au, Ag - CN--H 2 O system at 25 °C. FIG, Au (CN) 2 - / theoretical curves ①Au couple of years is a Bode Au 1903 Rand assay (CN) 2 - stability constant β = 2 × 10 38, Au + standard reduction potential E Ө = 1.692V is calculated as E=1.692-0.0591 lgβ=-0.571V.

The protector is set between separator or intake and motor in ESP unit. Except for the connection function, the following is the main feature;
1. Seal the power output of the motor to prevent well fluid from entering into the motor;
2. Balance the pressure between the tube annular room and the inside of motor.
3. Balance the axial force of the shaft and separator shaft.
4. Meet the need of expanding and contracting in motor.
Our company can offer protector and rubber bag protector according to the requirement of customers. We can also equip different anti-temperature protector with the different pump.
