Cause Analysis and Preventive Measures of Water Leakage in Mechanical Seals of Water Pumps
Leakage Phenomenon and Reasons Analysis
Installation is too loose
Measures to Prevent Water Leakage in Mechanical Seals
Measures to Prevent Leakage in Installation
We should improve the quality consciousness of installation works and strictly implement the institutionalization and standardization of installation and maintenance. Taking the tightness of the sealing ring as an example, the looseness of the rotating ring seal ring will affect the sealing effect, but the tightness may also aggravate the wear between the rotating ring and the bush, and cause fatigue and deformation of the rotating ring; while the static ring is relatively tighter, but too tightness will also lead to deformation or brittle cracking, so it must be measured and adjusted in accordance with the installation instructions to ensure that its compression meets the requirements.
Prevention and Treatment of Leakage in Use of Mechanical Seals
Daily inspection and use of pipeline system of mechanical seals is the guarantee of normal operation of mechanical seals. Therefore, the responsibility of equipment management should be implemented to people, and strict maintenance system should be formulated and implemented. Check all valves related to the operation of mechanical seals to ensure the integrity of safety monitoring instruments; check the smooth flow of cooling water of mechanical seal self-circulating water, culvert of pump, mechanical seal water pipeline, heat exchanger and mechanical seal water, no abnormal temperature changes, find out the problems and find out the causes in time, and solve them pertinently.
