D and DG series multi stage centrifugal pumps流量：6.3~450立方米每小时
The stuffing box is mainly composed of packing, water seal ring, packing cylinder, packing gland and water seal pipe. The function of stuffing box is mainly to block the gap between the pump shell and the pump shaft, so as to prevent the water flow in the pump from flowing to the outside and the outside air from entering the pump. Always adhere to the vacuum in the water pump! When the pump shaft and packing friction produce heat, it depends on the water seal pipe to hold water into the water seal ring to cool the packing! Adhere to the normal operation of the water pump. Therefore, in the process of pump operation patrol inspection, we should pay special attention to the inspection of stuffing box! Stop changing the packing after 600 hours of operation.
