1, 630 tons of new energy vehicle cover hydraulic pump and hydraulic motor and other mechanical connection to ensure concentric, or use flexible connection;
2, should be as far as possible to make the pump and motor output shaft by or less radial load, can not bear the radial force of the pump and motor shall not be pulley, gear and other transmission parts directly installed on the output shaft;
3. The leaking oil pipes of the pump and motor of the hydraulic press for 630 tons of new energy vehicles shall be unblocked, and generally no back pressure shall be connected. The oil drain pipe of the motor shall be led back to the oil tank separately. If it is connected with the oil return pipe, the pressure shall not exceed one atmospheric pressure;
4. The 630-ton new energy vehicle cover hydraulic motor should be filled with clean working fluid before starting for the first time to ensure the lubrication of the friction pair;
5. The motor with phase fine adjustment mechanism shall not be arbitrarily moved after adjustment. The motor with floating flow distribution mechanism shall be connected with hoses at its oil inlet and oil return ports to ensure 630 ton hydraulic pressFloatability of the distribution mechanism;
6. Pumps and motors with long downtime should not be started with full load and should be used normally after being idle for a period of time.
