Introduction to the Packing Sealing and Maintenance Methods of Single Stage Centrifugal Pump
The single-stage centrifugal pump packing seal is an important part of the sealing effect, so it is necessary for users to master its maintenance methods, so that the single-stage centrifugal pump packing seal can be promptly dealt with , Will not affect the normal operation of the pump, the following is a single-stage centrifugal pump packing seal maintenance methods introduced. Single-stage centrifugal pump packing seal repair methods introduced 1, cleaning centrifugal pump stuffing box, and check the shaft surface for scratches, burrs and so on. Stuffing box should be clean, shaft surface should be smooth. 2, check the shaft runout, rotor unbalance should be within the allowable range, so as not to vibration is too large, unfavorable to the packing. 3, in the stuffing box and the shaft surface sealant or coated with a suitable lubricant. 4, the packaging of the roll of packing, first take the root and journal size the same stick, the filler wound on it, and then cut off the knife, the best knife was 45 ° bevel. 5, packing to be filled by root, not a few filling. The method is to take a filler, coated with a lubricant, both ends of each holding the filler interface, opened along the axial direction, so that the spiral, and then from the incision into the journal. Do not pull along the radial direction to avoid misalignment of the interface. 6. Take a metal bushing with the same size material or lower shaft hardness as the stuffing box, push the packing into the deep part of the box, and apply a certain pressure to the bushing with the gland to pre-compress the packing. Pre-compression of 5% to 10%, up to 20%. Rotate the shaft a second time and remove the sleeve. 7, in the same way, filling the second root, third root. Note that when the filler is 4 to 8, the interface should be staggered by 90 ° when filling; the two filler should be staggered by 180 °; and the 3 ~ 6 should be staggered by 120 ° to prevent leakage through the interface. 8, the last packing filling, the application of gland compression, but the pressure should not be too large. At the same time by hand rotation axis, the assembly pressure tends to parabolic distribution. Then relax the lid a little. 9, run the test, if not sealed, and then squeeze some of the packing; if the heat is too large, relax it. This transfer was only droplet-like leaks and fever is not so far (the temperature of the filler site can only be higher than the ambient temperature 30 ~ 40 ℃), it can be formally put into use. In summary, single-stage centrifugal pump packing seal maintenance methods, in addition to single-stage centrifugal pump packing seal in the repair or replacement of mechanical seals, without removing the motor and pump cover.
