Description
Technical field
The present invention relates to pumps, and in particular to a kind of parts of bearings suitable for high temperature Pulp pump.
Background technique
The Pulp pump for conveying solid-liquid two-phase fluid, due to running environment complexity, operating condition is often very harsh, with
The promotion of smelting process technology in recent years, later by processing, directly uses slag by directly roasting to ore in smelting engineering
Stock pump conveys the ore pulp of high temperature by Pulp pump, and Pulp pump at runtime, often occurs because of bearing body temperature change
Bearing lubrication is bad, raceway, ball, the abrasion of retainer, it is difficult to which normal operation causes device to stop transport.
Summary of the invention:
In view of the deficiencies of the prior art, the present invention provides a kind of parts of bearings suitable for high temperature Pulp pump, so that knot
Structure stabilization and high temperature resistant operating condition.
In order to achieve the above object, the present invention is achieved by the following technical programs:
A kind of parts of bearings suitable for high temperature Pulp pump, including bearing body, bearing body is interior to be equipped with bearing and axis, feature
Be: the bearing body is fixed on pallet body, and adjustment screw is equipped in the pallet body, passes through bolt below the bearing body
It is connected in adjustment screw；Lower part is equipped with the oil storage room of rectangular-shape in the bearing body, and heat exchange is equipped in the bearing body
Device, the external cooling circulating water of heat exchanger.
Preferably, the heat exchanger is fixed in bearing housing by the cooling lid and connector for having cooling coil, is led to
It crosses external recirculated water and takes away the intracorporal heat of bearing housing.
Preferably, the bearing body exterior design has cooling fin, increases bearing heat-sinking capability.
Preferably, the bearing body both ends are equipped with bearing gland, and bearing gland is designed as labyrinth seal, passes through multiple teeth
Slot, resistance of the Lai Zengjia lubricating oil in leakage flow.
Preferably, the bearing gland is equipped with dust pan, and impurity, particle etc. can be effectively prevented into bearing housing.
Preferably, the axis, which rises, is equipped with disc, can be from bearing housing to bearing fuel feeding.
Conventional lower is that cylinder is changed to cuboid by bearing body oil storage room, and the calculating and scene by science are actual
Runtime verification, which increases radiating mode, and bearing body exterior design cooling fin by increasing oil reserve, into one
Step increases radiating mode, so that Pulp pump when pumping medium T≤160 DEG C, can efficiently control the temperature of bearing, make axis
Temperature is held not higher than 55 DEG C.The relative position of slurry pump impeller can be effectively reconciled after the bearing body installation by regulating device.
The service life that impurity, particle etc. enter bearing housing influence bearing can be effectively prevented in the dust pan.The bearing gland is set
It is calculated as labyrinth seal, by multiple tooth sockets, resistance of the Lai Zengjia lubricating oil in leakage flow, pressure difference is complete when leakage path both ends
Portion's loss, can be realized zero leakage.The disc can effectively promote the lubricity of bearing from bearing housing to bearing fuel feeding
Can, the oil ga(u)ge can observe oil level, so as to timely repairing.The heat exchanger can external cooling circulating water, can according to conveying be situated between
The temperature of matter selectively uses, and when external recirculated water, exchange capability of heat can be effectively promoted, in time by bearing because of medium high temperature
Conduction and load it is excessive and generate heat take away in time, it is ensured that the normal operation of bearing.
By the above means, effective solution bearing heating, bearing service life is short, the short easy oil leakage of oil sealing service life
The problems such as, keep reasonable whole pump configuration, stable, bearing long service life, axle envelope reliable, greatly reduce whole pump vibration and
Noise.
