How to prevent overheating of the fire pump stuffing box

Thread Content

　　Overheating of the stuffing box is a relatively common type of failure in fire pumps. Atlantic Pumping will analyze the reasons for overheating in several stuffing boxes. 　　1. The stuffing box does not have the correct packing. Insufficient packing, or improper installation or running-in, as well as overly tight packing, can all lead to overheating of the packing gland. To resolve this issue, it is necessary to check the condition of the packing, and adjust or replace it. 　　II. Wear of the packing or seal in the stuffing box allows air to enter the pump casing. To resolve this issue, it is necessary to determine whether it is the packing or the seal that is worn out, and replace the corresponding component; at the same time, it is important to check whether the lubrication is functioning properly. 　　III. Scratches on the shaft sleeve of the fire pump. To resolve this issue, it is necessary to repair, reprocess, or replace the shaft sleeve as required. 　　IV. Mechanical seal damage. To resolve this issue, the mechanical seal needs to be replaced. 　　V. The packing is too tight or the mechanical seal is not properly adjusted. To resolve this issue, the filler needs to be adjusted; if necessary, it must be replaced. 　　Single-stage fire pump http://www.eastseapump.com/
