The gap of spindle nose and sliding bearing sleeve is 0.10～0.15mm, the thickness of sliding bearing sleeve is 2～4mm, the plain bearing housing end has the Φ 5mm Cooling Holes that leads to spindle nose, and cooling, the lubricated medium that flows through by Pump Suction Nozzle of sliding bearing is realized through this Cooling Holes.
Rolling bearing in bearing housing is provided with two row, be provided with oil groove between two bearings and be injected with lubricant oil, oil groove positions is equipped with respectively the inside and outside spacer of bearing, and the circumference uniform distribution of bearing outer separator is provided with the aperture of 6 Φ 6, and when being convenient to pump work, two bearings is lubricated and cooling.
Be respectively arranged with bearing isolator on bearing housing and bearing cap, bearing isolator is arranged in the two ends of two row rolling bearings and rolling bearing is sealed in bearing housing, guaranteed that the thin oil in bearing housing does not leak outside, external agency does not enter in bearing housing, and sealing is reliable; Packing seal or mechanical seal are adopted in the sealing of pump cover and spindle nose.
Beneficial effect of the present invention is as follows.
1) this device is compared with traditional petrochemical process pump, structure is advanced, reliable, the generalization degree of pump is high, solved that radial load is large and the problem such as balance is bad, bearing seal is bad, the axial dimension that causes because of cantilever structure is large, volume large, the vibration large, noise is large, make whole pump operation reliable and stable, improve the working life of pump, also reducing due to volume, the minimizing of material, and reduced significantly cost.
2) because sliding bearing can bear larger radial force, impeller is arranged between sliding bearing and rolling bearing, make the impeller radial load that rolling bearing bears greatly reduce, reduced mechanical loss, improve the mechanical efficiency of pump, strengthened simultaneously the impeller support stiffness, reduced noise, improve product reliability.
3) the two end supports structure has shortened the pump shaft axial dimension, and economical with materials reduces processing and manufacturing difficulty, reduces pump group installing space, reaches the requirement of low-carbon economy.
4) because plain bearing housing is to be fixed in pump housing suction port place by 3 uniform gussets, be stabilier, improve the unsettled problem of import fluidised form, reduce simultaneously prewhirling of impeller inlet, improve hydraulic efficiency.
5) owing to adopting the double supporting structure pattern, help to control and dwindle the gap of pump housing choma and impeller port ring, reduce clearance leakage, improve the volumetric efficiency of pump.
5) pump cover is designed to jacket structuredly, when fed sheet of a media is high temperature, can carry out cooling to it; When fed sheet of a media is low temperature, can be incubated it, with protection machine envelope, the prolongation machine envelope life-span.
6) bearing housing and bearing cap are provided with bearing isolator, seal more reliable.
7) sealing of pump can adopt packing seal and two kinds of patterns of mechanical seal to satisfy the demand of different user.
