Abstract
The utility model relates to a turbine guide bearing for an LDTN condensate pump, which comprises a turbine guide bearing, and is characterized in that the inner wall hole of the turbine guide bearing is provided with a front and a rear groups of slots which store lubricating liquid in mutual dislocation, the two groups of slots for storing lubricating liquid are straight slots, each group of straight slots comprise a plurality of straight slots, and the straight slots are parallel to the axial direction of the inner hole wall. The two groups of slots for storing lubricating liquid are spiral slots, and each group of spiral slot comprises a spiral slot. The turbine guide bearing for LDTN condensate pump has the advantages that the lubricating effect is increased, the gaps of the turbine guide bearing is reduced, and the length of the turbine guide bearing is lengthened properly.
Description
Technical field
The utility model relates to a kind of LDTN condensate pump water pilot bearing.
Background technique
Existing water pilot bearing design straight trough or spiral chute are seen Fig. 1, Fig. 2, straight trough or spiral chute lubricate.But its shortcoming is 1, before and after water pilot bearing during no pressure difference, and lubrication effect is bad; 2, water pilot bearing gap hour, easily interlock.When the gap was big, vibration was big; 3, Design of length is limited, and it is bad to lead; 4, water pilot bearing is easy to wear, and the life-span is short, and maintenance cost is big.Therefore need be improved the structure of existing water pilot bearing, to address the above problem.
Summary of the invention:
The purpose of this utility model is that water pilot bearing is provided with straight trough or the existing the problems referred to above of spiral chute in the solution prior art, is provided a kind of water pilot bearing working life of improving, reduce maintenance cost, reduce the vibration of pump, improve the LDTN condensate pump water pilot bearing of water pump operation reliability.The utility model designs a kind of LDTN condensate pump water pilot bearing, comprises water pilot bearing, it is characterized in that: the groove of the storage Lubricants of two groups of mutual dislocation before and after offering on the inner hole wall of water pilot bearing.The groove of two groups of storage Lubricantss is a straight trough, and every group of straight trough has some straight troughs, and straight trough is parallel to the axial of inner hole wall.The groove of two groups of storage Lubricantss is a spiral chute, and every group of spiral chute is one.The utility model has the advantages that and improved lubrication effect, reduced the water pilot bearing gap, the length of the water pilot bearing that suitably extended.
Description of drawings:
Fig. 1, Fig. 2 are the prior art constructions generalized section,
Fig. 3, Fig. 4 are structural profile schematic representation of the present utility model (Fig. 3 is a straight trough, and Fig. 4 is a spiral chute),
Below in conjunction with accompanying drawing and construction embodiment the utility model is made detailed operation instruction.
Embodiment:
Comprise water pilot bearing 1 among the figure, it is characterized in that: the groove of the storage Lubricants of two groups of mutual dislocation before and after on the inner hole wall of water pilot bearing, offering.The groove of two groups of storage Lubricantss is a straight trough 2, and every group of straight trough has some straight troughs, and straight trough is parallel to the axial of inner hole wall.The groove of two groups of storage Lubricantss is a spiral chute 3, and every group of spiral chute is one.
Owing to adopted the groove of the storage Lubricants of two groups of mutual dislocation, set up many places circular groove storage Lubricants, make the water pilot bearing lubrication effect better; Reduce the water pilot bearing gap, increase water pilot bearing length, make the water pilot bearing guiding better, the vibration of pump reduces, and has improved the operational reliability of pump.
Claims (3)
