5, for installation in a pump when the mechanical seal ISW50-250A mechanical seal cavity open end portion of the contact by the sealant must be sealed to prevent leakage of the liquid from the gland. 6, in order to reduce friction on the shaft or sleeve and the seal contact area can be evenly coated with oil or grease or clean water or soap and water, but should be noted that, when elected with ethylene-propylene rubber "O" rings, not with mineral oils and lipids in contact ISW50-250I mechanical seals, clean water or silicone oil and lubrication. Stationary ring "O" ring lubricated with water, external pressure is applied to install stationary ring. 7, when the small spring mechanical seals, check the small spring are the same length and rigidity. The spring rotation to the relevant mechanical seal (ie fixed rotation to the mechanical seal) from the stationary ring to the rotating ring and the shaft see rotation, clockwise rotation of the shaft need to right-handed spring, and vice versa for left-handed. 2) ring seal is not tight as possible. In fact, detrimental tight ring seals, one increased wear ring and sleeve between the premature leakage; the second is to increase the axial adjustment ring, the resistance movement can not be properly adjusted when conditions change frequently ; three spring fatigue easily damaged; four is to deform ISW50-250B ring seals mechanical seals, affect the sealing effect. (3) stationary ring seal is not tight as possible. Stationary ring seal basically at a standstill, when the relatively tight sealing effect would have been better, but too tight is harmful. One cause static ring seal excessive deformation, affecting the sealing effect; the second is mostly static ring material with graphite mechanical seal, are generally more brittle, excessive force can easily cause fragmentation; third is to install, difficult to remove, easy to damage the stationary ring.
