Gear pump mechanical seal leakage of the main reasons
Gear pump mechanical seal leaks the main reason Gear pump mechanical seal a wide range of different models, but the main points of leakage are the following: (l) sleeve and shaft seal; (2) between the moving ring and sleeve seal ; (3) moving, static seal between the ring; (4) on the stationary ring and the ring seat between the seal; (5) seal the seal between the cover and the gear pump body. Generally speaking, it is easy to find out and solve the leakage between the shaft of the sleeve and the seal between the cover and the gear pump. However, careful observation is required. Especially when the working medium is liquefied gas or high pressure, toxic and harmful gas, the relative Difficulties. The rest of the leakage intuitively difficult to distinguish and judge, to be long-term management, maintenance practice, based on the leakage symptoms observed, analyzed and judged in order to draw the correct conclusion. Gear pump mechanical seal leak analysis and determine the reasons: 1. Static test leaks. Mechanical seal installation and commissioning is good, the general should be static test, observe the amount of leakage. If the leakage is small, mostly ring or static ring seal problems; leakage is large, then that dynamic and static friction ring there is a problem. In the initial observation of the leakage, to determine the leakage site, based on manual observation disk, if the leakage was no significant changes in the static and dynamic ring seal problems; such as the disk when there is a significant change in leakage can be concluded that the move, Static friction ring there is a problem; such as the leakage of media along the axial injection, the dynamic ring seal there are many problems, leakage to the surrounding medium jet or water leakage from the hole, the more static ring failure. In addition, the leak channel can exist at the same time, but generally there are major and minor differences, as long as careful observation, familiar with the structure, we must be able to correctly judge. 2. Leakage during commissioning. Gear pump mechanical seal after static test, the centrifugal force generated by high-speed rotation of the operation, will inhibit the media leakage. Therefore, the test run when the mechanical seal leakage excludes the seal between the shaft and the end cover, basically due to dynamic and static friction ring caused by damage. The main factors that cause the failure of the friction seal are: (1) the operation, due to time, cavitation, pressure and other anomalies, causing a large axial force, the dynamic and static contact surface separation; (2) Mechanical seal when the amount of compression is too large, leading to serious friction end face wear, abrasions; (3) ring seal is too tight, the spring can not adjust the axial displacement of the moving ring; (4) (5) There is granular material in the working medium, into the friction pair in operation, flaw detection dynamic and static ring seal face; (6) design selection is wrong, the seal Low end pressure or sealing materials such as larger shrinkage. These phenomena often appear in the trial operation, and sometimes can be eliminated by adjusting the static ring seat, etc., but most need to re-disassemble, replace the seal. 3. Suddenly leak during normal operation. Stainless steel gear pump suddenly leaks in operation due to a few normal wear or life has been reached, and most are due to larger changes in operating conditions or improper maintenance. (1) evacuating, cavitating or holding pressure for a long time, resulting in seal failure; (2) the actual output of the gear pump is too small, a large number of medium gear pump cycle, heat accumulation, causing gasification of the medium, resulting in seal failure; 3) the return flow is too large, resulting in inhalation tube side of the container (tower, kettle, tank, pool) at the bottom of sediment damage, damage to the seal; (4) for a long time outage, restart without manual turning, friction pair Due to the adhesion and tear the sealing surface; (5) medium corrosive, polymeric, colloidal substances increased; (6) dramatic changes in ambient temperature; (7) frequent changes in conditions or adjustments; (8) Stop and so on. Centrifugal gear pump in normal operation, a sudden leak, if not found in time, often lead to a larger accident or loss, we must pay attention to and take effective measures.
