Axial flow pump fill letter installation steps

Axial flow pump fill letter installation is the need for a certain step, we explain the steps about the axial flow pump fill letter:
(1) Install the upper sleeve on the journal of the pump shaft.
If no bushings. Can be cut after the journal.
(2) Install the bottom lining. Installation to even force force. So that the pump shaft to maintain a certain degree of coaxial requirements.
(3) Install the packing. Common packing model is YS450F. The size of the specification is expressed by the length of the length. The unit is mm, the difference is generally 3.0mm, the packing size should be equal to the inner diameter of the packing chamber minus half of the outer diameter of the sleeve. As the filler for the square section, so before the installation should be cut in advance, each lap at both ends cut into 30 ° ~ 45 ° oblique interface, and in the oil soaked, by lap. Layer and layer interface to be staggered, generally staggered 120 ° ~ 180 °.
(4) Install the seal ring. To make the seal ring at the nozzle of the water seal.
(5) Install the packing gland. Axial pressure to 0.05MPa is also appropriate to use both hands to twist the pump shaft test, a little feel can be difficult. Until the test run, and then according to the stuffing box leakage, make the appropriate tightness adjustment.
