Here, the sealing surface for signs of wear still need to add the following ISW65-200 mechanical seal, check the wear marks that can help analyze failures. (1), and wear wider: Indicates the pump was a serious misalignment. The reason is: a, bearing damage; b, shaft vibration or axial deformation; c, shaft bending; d, pump cavitation vibration; e, uncoupled pair; f, severely deformed tube; g, seal stationary ring tilt. (2), wear scar narrowing: wear scar than the minimum width of the two narrower ISW65-160A sealing surface of the mechanical seal, which shows the sealing overpressure, pressure or temperature of the sealing surface deformation. (3), no wear marks: Description sealing surface is not bonded. Check the springs and other compensation mechanism is slipping or impeded. (4), the sealing surface no wear marks, but there are bright spots. Sealing surface will be a bright spot without warping wear scar. High pressure mechanical seals, gland bolts screwed good or not good clip, or pumps can form a rough surface highlights. When using two bolts of the gland, the stiffness is not enough, the deformation is another cause of highlights. When this symptom description: A car on the seal may leak 15, by the spring drive mechanical seal, spring rotation should be a reasonable choice, usually from the motor to the impeller end of the shaft is clockwise, the spring should be selected right-handed , otherwise it is left-handed spring. 16, when the ring is installed, for a single end mechanical seal shall ensure that the working height or compression. Under normal circumstances, according to the record size of the original mechanical seals during disassembly and according to the degree of wear can make appropriate adjustments. When tightening the screws, be sure to use the end of the depth gauge to detect the sealing surface shall not exceed the beating 0.025mm. For the double-end mechanical seal, only the anti-rotation screw into the anti-rotation slot can (be careful to check whether their move around freely). However, according to Morgan Stanley to be appropriate to increase the extent of damage the sealing surface of the pad to adjust the amount of compression adjustment (which can add and subtract in the stationary ring gasket can also subtract gasket between the lid and the back cover). 17, must be injected into the liquid before the operation, and then turn a few laps to make sure that the sealing surface in lubrication. For the double-end mechanical seal needs to join the cool water, ISW65-160IA mechanical seal _ _ pipeline pump mechanical seal is provided by Anguo Shi Yuan Pumps Limited. Anguo Shi Yuan Pump Co., Ltd. (www.shiyuanbeng.com) strong, credible, in Baoding centrifugal pumps and other industry has accumulated a large number of loyal customers.
