Importance of shaft sleeve in water ring vacuum pump

Water ring vacuum pump, especially large water ring vacuum pump, its value is tens of thousands of less value, more value of hundreds of thousands, and as the only friction seal rope assembly, design and installation, the shaft sleeve plays the following role:

1, keep the shaft without wear, the shaft sleeve is generally made of wear resistant alloy, which is characterized by wear resistance, high hardness, smooth surface, no rust, so protect shaft wear

Two, because of the characteristics of the shaft sleeve, to ensure that the sealing rope wear less, extend the life of the sealing rope

Three, to ensure that a longer period of downtime, not due to rust and cause the rotor stuck, unable to move

Four, convenient maintenance, reduce maintenance costs

And at present many manufacturer use cast iron to pledge to make axle sleeve character to reduce cost, lose the original idea of axle sleeve completely, have no effect at all
