Description
Technical field
A kind of pump is the utility model is related to, more particularly to a kind of closure for axial-flow pump.
Background technology
Axial-flow pump makes the pump shaft stream that liquid conveys in the axial direction to active force caused by liquid by the blade of spinning roller impeller
Impeller of pump is equipped with 2 ~ 7 blades, in tubular pump case internal rotation.Fixed guide vane is housed, to eliminate on the pump case of upper impeller
The rotary motion of liquid, clear water, slight sewage can be conveyed, medium temperature double-mechanical sealing, can prevent leak up to 40 DEG C,
Mammoth pump is because axial force is big, and using special thrust bearing, lubrication is abundant, and bearing service life length, pump pulls the plug, pump fortune
Row is steady.
When being flowed through due to the fluid in axial flow pump body with certain speed, the liquid in seal case causes because poorly sealed
Leak, liquid water outlet vertically, overflowed to bearing housing direction to a certain degree；The power transmission shaft of rotation drives at a high speed in bearing housing
Bearing rotates, and its interior lubricating oil is with axially oozing out, and the relatively broad axial-flow pump used has vertical, and pump pulls the plug, transmission
Axle is longitudinally driven, poorly sealed, leak is present or is leached the leakage problem of oil.Closure is commonly used on general axial-flow pump, by
In needing anticorrosion, machine-shaping is mostly cast using stainless steel, because the part belongs to thin wall type, the deflection of stainless steel is big,
Difficulty is added to casting, processing, simultaneously as deformation also adds difficulty to the maintenance dismounting of pump, it is extremely inconvenient, it have impact on
The normal operation of production, the quality weight of stainless steel, inaction add electric energy；Thus need consider reduce liquid or oil let out
Dew, environment is not contaminated, and maintenance time is short.
Utility model content
Problem to be solved in the utility model is that axial-flow pump closure is easier to reveal in work is run, and changes, ties up
Repair the problem of closure is especially difficult, there is provided a kind of closure for axial-flow pump, good sealing effect, and simple, maintenance is installed
Time is short, is greatly enhanced production efficiency.
In order to solve the above technical problems, the technical solution adopted in the utility model is：A kind of closure for axial-flow pump,
Including power transmission shaft, axle sleeve, seal combination and seal case are equipped with axle sleeve respectively, bearing, bearing housing are equipped with power transmission shaft
Gland and bearing housing, it is characterised in that：Closure, the bearing housing pressure are installed between the seal case and bearing housing
Lid one end is provided with bearing housing gland groove, and described closure one end is provided with closure tongue, the closure tongue setting-in
In bearing housing gland groove.
The closure is packed on power transmission shaft and can rotated along bearing housing gland groove.
Closure ○ shaped circle is set in the closure.
The closure makes shaping using superhigh molecular weight polyethylene material.
Axle sleeve ○ shaped circle is set in the axle sleeve.
The utility model has the advantages and positive effects of：
1st, the utility model is used for the closure of axial-flow pump due to being provided with tongue, bearing housing gland using closure one end
One end sets bearing housing gland groove structure, and closure one end tongue is inlaid in bearing housing gland groove, and closure is packed in
It can rotate on power transmission shaft and in bearing housing gland groove, both block oil immersion in bearing housing and gone out, while be set in closure close
○ shaped circle is covered, sealing effectiveness is more preferable, and sealing effectiveness is significantly stronger than mechanical seal, reduces production cost, reduces liquid
Leakage, is effectively protected that environment is not contaminated, and desulfurization pump and axial-flow pump application effect are good, generally applicable various different pump classes.
2nd, the utility model is used for the closure of axial-flow pump due to installing closure between seal case and bearing housing
Structure, block seal case liquid again using closure and enter bearing housing, good sealing effect, and assemble and disassemble simple, maintenance time
It is short, improve production efficiency.
3rd, the utility model is used for the closure of axial-flow pump using using superhigh molecular weight polyethylene material making shaping, weight
Amount is gently without processing.It has the wearability of superelevation, corrosion-resistant, impact resistance, and ageing resistace is strong, and it is indeformable, cost is low etc.
Advantage, while also have good non-adhesion behavior, self excellent greasy property.
