9, Try to control ZJ/ZJP roots vacuum pump capacity and head, within the scope of the specified on the sign in order to make sure what ZJ had type roots vacuum pump running at peak efficiency, to achieve maximum energy saving effect;

10, When roots vacuum pump to stop using, first close the gate valve, pressure gauge, then stop the motor;

11, When ZJ/ZJP type roots vacuum pump in the process of operation, the bearing temperature cannot exceed environment temperature to 35 c, the highest temperature should not exceed 80 c;

12, When roots vacuum pump in the first months of work, the oil change 100 hours, every 500 hours, after oil change once;

13, Often adjust the packing gland, packing materials indoor drip situation is normal (in a drip out as appropriate);
