Abstract
The utility model discloses a kind of self lubricating bearing means of centrifugal pump, comprise bearing support (7), bearing cap (2), rotating shaft (6), top bearing shell (3), lower bearing (9), disc (5) are housed in this rotating shaft, the inner wall surface of described top bearing shell (3), lower bearing (9) all has Babbitt Metal layer (10), on the Babbitt Metal layer (10) of this top bearing shell or lower bearing, is provided with groove (8).Lubricant oil in the groove of the utility model top bearing shell or lower bearing, by the direct drive of rotating shaft, can meet the self-lubricating function of bearing shell parts moment immediately.Thereby the tile kilning phenomenon of bearing shell moment while effectively having avoided centrifugal pump start; solved centrifugal pump frequent startup-shutdown affect bearing shell working life and moment tile kilning and the irregular operation situation that causes; improve the bearing means greasy property of centrifugal pump, and can make again bearing shell parts there is better abrasionproof anti-corrosion performance.
Description
Technical field
The utility model relates to a kind of centrifugal pump, specifically relates to a kind of bearing means of horizontal multi-stage centrifugal pump.
Background technique
At present; because horizontal multi-stage centrifugal pump is in stopping process; disc in its bearing means quits work; make in the gap between bearing shell parts (comprising top bearing shell and lower bearing etc.) and rotating shaft in non lubricant oil state; in the time that centrifugal pump one is started shooting; because disc moment has little time to bearing shell fuel feeding, thereby can make bearing shell produce the tile kilning phenomenon of moment.As frequent in centrifugal pump startup-shutdown, will certainly affect the working life of bearing shell, thereby affect the stable operation of pump assembly.
Summary of the invention
The purpose of this utility model is to overcome above-mentioned deficiency, and prevents the self lubricating bearing means of the centrifugal pump of bearing shell moment tile kilning when a kind of simple in structure, centrifugal pump start is provided.
The utility model object realizes by following technical solution: the self lubricating bearing means of centrifugal pump, comprise bearing support, bearing cap, rotating shaft, top bearing shell, lower bearing, disc are housed in this rotating shaft, the inner wall surface of described top bearing shell, lower bearing all has Babbitt Metal layer, on the Babbitt Metal layer of this top bearing shell or lower bearing, is provided with groove.
Adopt after the utility model structure, lubricant oil when start in the groove of top bearing shell or lower bearing, by the direct drive of rotating shaft, can meet the self-lubricating function of bearing shell parts moment immediately.Then along with disc normal fuel injection; thereby the tile kilning phenomenon of bearing shell moment while effectively having avoided centrifugal pump start; solved centrifugal pump frequent startup-shutdown affect bearing shell working life and moment tile kilning and the irregular operation situation that causes, improved the bearing means greasy property of centrifugal pump.
Brief description of the drawings
Below in conjunction with accompanying drawing and mode of execution, the utility model is described in further detail.
Fig. 1 is the structural representation of the self lubricating bearing means of centrifugal pump of the present invention.
Fig. 2 is the structural representation of the bearing shell parts (comprising top bearing shell and lower bearing) in Fig. 1.
Embodiment
With reference to Fig. 1, Fig. 2 is known, the self lubricating bearing means of the utility model centrifugal pump, comprise bearing support 7, bearing cap 2, rotating shaft 6 (and labyrinth ring 1), in this rotating shaft 6, top bearing shell 3 is housed, lower bearing 9 (and bearing shell gland 4), disc 5, described top bearing shell 3, the inner wall surface of lower bearing 9 all has Babbitt Metal layer 10 (coating), on the Babbitt Metal layer 10 of this top bearing shell 3 or lower bearing 9, being provided with groove 8 (is arranged on lower bearing 9 as shown in Figure 2, described groove 8 is " V " font or " U " font or other approximate shapes, can be three, be conducive to oil storage).
Wherein, described top bearing shell 3 and lower bearing 9 be closing and being placed on bearing support 7, and be connected with rotating shaft 6 and to use bearing shell gland 4 to push down fixing, then cover bearing cap 2.After centrifugal pump is shut down, in these three " V " fonts or " U " font groove 8, still filling with lubricant oil, in the time that centrifugal pump is started shooting for the second time, lubricant oil in groove 8 on top bearing shell 3 or lower bearing 9 is by the direct drive of rotating shaft, bearing shell parts be can meet immediately and (top bearing shell 3 and lower bearing 9 comprised, can be referred to as bearing shell) lubrication of moment, thereby while having realized centrifugal pump start, prevent the object of bearing shell parts moment tile kilning, and because top bearing shell and lower bearing inner wall surface are provided with Babbitt Metal layer, can make again bearing shell parts there is better abrasionproof anti-corrosion performance.
Claims (2)
1. the self lubricating bearing means of centrifugal pump, comprise bearing support (7), bearing cap (2), rotating shaft (6), top bearing shell (3), lower bearing (9), disc (5) are housed in this rotating shaft (6), it is characterized in that: the inner wall surface of described top bearing shell (3), lower bearing (9) all has Babbitt Metal layer (10), on the Babbitt Metal layer (10) of this top bearing shell (3) or lower bearing (9), be provided with groove (8).
2. the self lubricating bearing means of centrifugal pump as claimed in claim 1, is characterized in that: described groove (8) is " V " font or " U " font.
