Bearing isolator technology parameters

Bearing isolator parameters: 1. Material: copper, filled PTFE composite ring, fluorine rubber 2. Temperature: - 3 34 to 204 degrees Celsius. Surface speed: 60. 9m/s４. Axial motion, plus or minus 0. 64 mm5。 Don't concentricity & radial runout degrees: plus or minus 0. 51mm６. Pressure: the atmospheric specific please see attachment 'Guardian technology parameters' the oil seal of equipment requirements are as follows: 1. The diameter of axle diameter tolerance recommendation: + 0. 076 ( mm) 2. The inner diameter of the hole tolerance: + 0. 051 ( mm) 3. Axis of finish recommendation: not less than 1. 63µ m4. Hole finish recommendation: not less than 2. 54µ m5. The hardness of shaft and hole requirements: no. 6. Shaft and hole needs to have certain chamfer to install installation: preparations before the isolator installed equipment, all equipment must be thorough check. Disconnect power supply system, follow all safety procedures to install the separator. Check the surface of the shaft and hole, bright and clean degree of shaft should be not less than 64 & micro; 在( 1. 63µ m） 。 But also do not need too bright and clean. Finish should be not less than 100 & micro hole; 在( 2. 54µ m） 。 The edge of the shaft and hole should be appropriate, such as a bevel edge. To prevent scratches o-rings. Shaft and hole any defect cannot affect the installation of oil seal. Defect type spiral machining marks, sharp chamfering, Nick, cymbal, gap, and erosion, and so on. Remove all foreign flaws. In many case, shaft due to the wear and tear of the old oil seal leaves a groove. Should pay attention to and ensure the new isolator o-rings don't seal in the same position. If the surface of the shaft is a key or ridge, when installation, it must be covered. Here can use some installation tools, such as plastic bags, thin copper with smooth edges, or a smooth on the edge of the board. Seal check Garlock Klozure Guardian, MICRO - ISO - TEC II GARD, and Equalizer, bearing isolator is complete. Any attempt to its separation will cause the damage of the seal, and we do not guarantee. Check the o-rings outer diameter and inner diameter, o-rings are not allowed to be any damage, topped with a small amount of lubricating oil. Install with the hand will be flat on the shaft of seals, as shown in figure 14. If there is a drain seal, please send the rotation to six points location. 卫报,微 ISO - TEC II GARD, the outer diameter of the stator in a slot, the slot should be rotated to the 12 o 'clock position, make sure to drain into the appropriate position. The Equalizer isolator can be installed in any direction, also do not need the positioning, as shown in figure 15. Seal with the hand gently into hole, if it is necessary to use a tool to tap the soft surface. When the seal surface and the surface of the bearing surface or hole together at ordinary times, completely sealed. As shown in figure 16. Install follow-up examination when the seal is installed, carefully check the sealing parts, see if it has damage to the seal, make sure that the rotor can gently with the axis of rotation. Any submerged bearing isolator, and the plugging of discharge hole could lead to seal failure. Remove the old isolator disassembly and installation methods are similar, but from behind the operation, the seal if unable to gain access to the rear, it gently pry it out bit by bit from the bearing seat. To avoid damage to the shaft and bearing seat.
