Reasonable maintenance of gear pumps during operation can ensure their long-term, stable, and efficient operation. Several important maintenance tasks should be performed during the operation of gear pumps. The following is a detailed explanation provided by Yutong Pump Industry. 1. Startup: (1) Check the sealing of all pipeline flanges and joints before starting. (2) Rotate the coupling to ensure there are no friction or collision sounds. (3) For the first startup, inject the conveying liquid into the pump. (4) Before starting, fully open the valves in the suction and discharge pipelines. Starting with closed valves is strictly prohibited. (5) Verify the motor rotation direction before starting the motor. 2.

　　Proper maintenance of gear pumps during operation is essential for their long-term, stable, and efficient performance. Several important maintenance tasks should be performed during gear pump operation; Yutong Pump Industry will provide a detailed explanation below.

　　1. Startup:

　　(1) Before starting, check the sealing of all pipeline flanges and joints.

　　(2) Manually rotate the coupling to ensure there are no friction or collision sounds.

　　(3) For the first startup, the pump should be filled with the liquid to be conveyed.

　　(4) Before starting, fully open the valves in the suction and discharge pipelines. Starting with closed valves is strictly prohibited.

　　(5) Verify the motor rotation direction before starting the motor.

　　2. Shutdown:
