The circuit breaker above the terminal as the power line is usually called the power supply terminal, the lower terminal is usually used as the load connection is called the load terminal. So can the power connected to the load side, and the load connected to the power side? No. Because in our country, the most widely used in the field of electric shock protection is the electronic leakage circuit breaker. Since the tripping coil of the electronic leakage circuit breaker is charged instantaneously only when the operation signal is obtained, when the tripping circuit of the leakage circuit breaker is tripped, Power off immediately. If the leakage circuit breaker on the line and under the line connected reverse, resulting in leakage circuit breaker action, the voltage is still added to the trip coil, it will burn the coil, so that the entire leakage circuit breaker loss of leakage protection.

1.Before installation, carefully check whether the model and specifications of the sealing kit match the hydraulic cylinder, and whether there is any damage or deformation.
2.Before installing the sealing kit, the interior of the hydraulic cylinder should be cleaned thoroughly and checked for foreign objects, sand particles, and other impurities to avoid affecting the sealing effect.
3.When installing the sealing kit, special tools should be used to avoid using hard metal tools or manual tools to avoid damaging the sealing kit.
4.When installing sealing kits, attention should be paid to the direction and position to ensure that each sealing kit is installed correctly to avoid leakage or poor sealing.
5.When installing the sealing kit, attention should be paid to applying lubricating oil or lubricant to make it easier to install and improve the sealing effect.
6.After installing the sealing kit, pressure testing and running should be carried out to ensure the sealing effect and the normal operation of the hydraulic system.
