Description
Technical field
The utility model is related to technical field of bearings, more particularly to a kind of vertical with holdback for pump motor is pushed away
Power sliding bearing.
Background technology
Pump is trandfer fluid or makes the machinery of fluid pressurized.It sends the mechanical energy of prime mover or other external energies to
Liquid, increases liquid energy.Pump is mainly used to the liquid such as conveying water, oil, acid ＆ alkali liquid, emulsion, suspended emulsion and liquid metal,
Also liquid, gas mixture and the liquid containing suspended solids can be conveyed.Pump generally can be divided into positive displacement pump, dynamical type by operation principle
Pump and the class of other types pump three.In addition to classifying by operation principle, can also be classified and be named by other method.Such as, by driving method
Electrodynamic pump and turbine pump etc. can be divided into；Can be divided into single-stage pump and multistage pump by structure；By purposes can be divided into boiler feed pump and based on
Amount pump etc.；Can be divided into water pump, oil pump and slush pump etc. by the property of conveying liquid.According to axle construction is whether there is, straight line pump can be divided, and
Conventional pump.Water pump can only convey the logistics with fluid as medium, it is impossible to conveying solid substance.
Pump plays lifting, conveying and the work of drug metering of sewage as the power-equipment in water treatment procedure,
Its importance is self-evident, is once gone 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 axle is made to move axially.Two friction surfaces are complete
Hydrodynamic thrust bearing and hydrostatic pressure thrust bearing are divided into by the thrust bearing that fluid film separates, it is adaptable to middling speed fortune high
OK.The thrust bearing that two friction surfaces can not be separated by fluid film completely works under boundary lubrication, is only applicable to low cruise.
Motor typically all uses common integral vertical type thrust slide bearing (as shown in Figure 1), vertical thrust slide bearing
It is a thrust collar 41 for rotation by a guide shaft bearing 43, a set of guide tile 42 and a set of thrust bearing shoe valve 44 are constituted.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 the minute surface of thrust collar 41
On shape thrust bearing shoe valve 44.Thrust collar 41 adds locking key device with motor shaft from interference fits.
In water resources projects, there are some special requirements for hydroelectric machine shafting.Hydroelectric machine shafting needs single direction rotation, but
There is water when being termination of pumping in pump line, because losing the power of pump, water can produce the backflow of backflow phenomenon, water shafting can be caused anti-
Turn, existing solution is that check-valves is set in pipeline, and water valve is closed while termination of pumping.Check-valves price in pipeline is held high
Expensive, the especially check-valves of mammoth pump, its price is essentially identical with the price of motor body.
