Technical field
The present invention relates to Pulp pump field of sealing technology, more particularly to a kind of slurry pump packing structure and are based on packing seal knot
The improved method of structure.
Background technique
Pulp pump is the core equipment of grain slag system, and the sealing means of centrifugal type slurry pump have packing seal and machinery close
Envelope.Due to grain slag be coking wastewater, dirt is more, and mechanical seal is unable to satisfy duty requirements, the slurry in grain slag region
Pump the soft packing seal (being commonly called as packing) for being all.
There are a large amount of leakage problems of packing in grain slag Pulp pump.Since water temperature is high and with pressure, the water of leakage can penetrate into pump
Bearing housing pollutes lubricating oil, pump bearing is caused to damage, while environment is also polluted in leakage.Repeatedly replacement packing can not all solve axis
Leakage problem is sealed, pump manufacturer and packing supply commercial city are sent people over here on-the-spot guidance replacement operation during packing replacing, and each
Class material packing was all tried out, and a large amount of leakage problems of packing can not be all solved.
By analysing in depth to the investigation of live phenomenon with reason, it is more that coking wastewater contains all kinds of chemical substances, infiltration and
Corrosive power is stronger, when penetrating through packing, will form one layer of dirt between packing and axle sleeve, and lasting leakage can allow this layer of dirt
Object increases thickening, and packing is caused largely to leak, and to solve packing leakage problem, with emphasis on asking for solution coking water penetration packing
Topic.
