如果切换电流太高，造成的温度升高和接触电弧将会劣化继电器并缩短接触寿命。
If the switched current is too high, the resulting temperature increase and contact arcing will degrade the relay and shorten the contact life.
在低氰镀液中含量太高则电流效率下降，甚至其成海绵状镀层。
In the low cyanide solution content is too high, the current efficiency drops, and even has cavernous coating.
主要是泵的转速太高、介质粘度又太高这样就会造成泵阻力很大，电机的瞬间启动电流超过额定电流，造成电机过载；
Mainly is the pump speed is too high, medium and high viscosity resistance is very big, this will cause pump motor moment of starting current more than rated current, motor overload;
