Description
Technical field
The present invention relates to technical field of bearings more particularly to a kind of vertical thrust with holdback for pump motor are sliding
Dynamic bearing.
Background technique
Pump is trandfer fluid or the machinery for making fluid pressurized.It sends the mechanical energy of prime mover or other external energies to
Liquid increases liquid energy.Pump is mainly used to convey the liquid such as water, oil, acid & alkali liquid, emulsion, suspended emulsion and liquid metal,
Also liquid, gas mixture and the liquid containing suspended solids be can transport.Pump can be usually divided into positive displacement pump, dynamical type by working principle
Pump and other types pump three classes.In addition to by working principle classification, also it can be classified and be named by other methods.Such as, by driving method
Electrodynamic pump and turbine pump etc. can be divided into；Single-stage pump and multistage pump can be divided by structure；By purposes can be divided into boiler feed pump and based on
Amount pump etc.；Water pump, oil pump and slush pump etc. can be divided by the property of conveying liquid.According to whether there is or not axle construction, straight line can be divided to pump, and
Conventional pump.Water pump can only convey the logistics using fluid as medium, be unable to conveying solid substance.
Pump plays the promotion, conveying and the work of drug metering of sewage as the power-equipment in water treatment procedure,
Its importance is self-evident, once goes wrong in the pumping unit of some key links, can all pull one hair and move the whole body.
Thrust slide bearing is subject to axial thrust and limits the sliding bearing that axis work moves axially.Two friction surfaces are complete
The thrust bearing separated by fluid film is divided into hydrodynamic thrust bearing and hydrostatic pressure thrust bearing, is suitable for high middling speed and transports
Row.Two friction surfaces cannot be worked under boundary lubrication by the thrust bearing that fluid film separates completely, be only applicable to low speed operation.
Motor generally all uses common integral vertical type thrust slide bearing (as shown in Figure 1), vertical thrust slide bearing
It is by a guide bearing seat 43, the thrust collar 41 of a rotation, a set of guide tile 42 and a set of thrust bearing shoe valve 44 form.Necked part
Radial load be loaded on the guide shoe 42 of arc by thrust collar 41, and axial thrust load is loaded into circle by 41 mirror surface of thrust collar
On shape thrust bearing shoe valve 44.Thrust collar 41 and motor shaft select transition fit to add locking key device.
In water resources projects, there are some special requirements for hydroelectric machine shafting.Hydroelectric machine shafting needs single direction rotation, but
There are also water in pump line when being termination of pumping, because losing the power of pump, water can generate backflow phenomenon, and it is anti-that the reflux of water will lead to shafting
Turn, existing solution is that check-valves is arranged in pipeline, and termination of pumping while closes water valve.Check-valves price in pipeline is high
Expensive, the price of the especially check-valves of mammoth pump, price and motor body is essentially identical.
Summary of the invention
