Pass in the inner chamber of bearing body, lead to the lubricant effect of bearing to decline, pollute lubricating oil, or even cause bearing damage.
It is to guarantee that bearing body is not intake at present, often after a while it is necessary to shut down centrifugal pump fuel tank or bearing body are entered
Row checks, so not only bothers very much, detection efficiency is low, and can affect normal production work.
Utility model content
For deficiencies of the prior art, the purpose of this utility model is to provide a kind of centrifugal pump bearing health check-up
Leakage device, can carry out on-line monitoring to leak, thus monitor in real time water leakage situation, and can carry out when water leakage is larger
Alarm, thus avoid water leakage to enter bearing intracoelomic cavity, to ensure the stability of bearing body running.
In order to solve above-mentioned technical problem, the technical solution adopted in the utility model is such that a kind of centrifugal pump bearing
Health check-up leakage device it is characterised in that: include support, water collector and mozzle, described support include horizontally disposed base plate and
Vertically the support bar on base plate, is provided with a link, described link and support bar are slidably connected on this support bar, and
Can fix with support bar；Described water collector is fixedly connected with link, and one end of described mozzle is connected with water collector；In collection
The outside level of hydrophone is provided with a warning line, is provided with a float switch in water collector, described float switch pass through holding wire with
Control system is connected, and when the ball float of float switch floats to warning line position, can send signal to control system.
Further, described mozzle is connected with the bottom of water collector.
Further, the described float switch of institute includes ball float, magnetic strength element and wiring gauge outfit, wherein, described ball float and magnetic
In water collector, described wiring gauge outfit is installed on the top of water collector to sensing unit, and is connected with control system by holding wire.
Further, described support bar is vertically provided with a bar hole, described link passes through the tight of bar hole by one
Fixing bolt is connected with support bar.
Compared with prior art, the utility model has the advantage that structure is simple, easy to use；By water conservancy diversion during use
The other end of pipe is connected with the water storage tank between bearing body and centrifugal pump, makes water collector pass through to form a liquid level meter, and passes through
Liquid level in float switch real-time monitoring water collector, thus realize the real time on-line monitoring to liquid level in water storage tank, when liquid level arrives
When reaching warning line position, alarm signal can be sent to control system such that it is able to prompting is processed, in time effectively to prevent
Bearing intracoelomic cavity leads to the lubricant effect of bearing to decline because of water inlet, or even causes bearing damage etc., thus ensureing bearing body work
The stability made.
Brief description
Structural representation when Fig. 1 uses for the utility model.
Fig. 2 be Fig. 1 along a a to cut-away view.
In figure: 1 support, 2 water collectors, 3 mozzles, 4 float switches, 5 warning lines, 6 centrifugal pumps, 7
Bearing body, 8 axle envelopes.
Specific embodiment
Below in conjunction with drawings and Examples, the utility model is described in further detail.
Embodiment: referring to Fig. 1, Fig. 2, a kind of bearing block of centrifugal pump leakage detection apparatus, including support 1, water collector 2 and water conservancy diversion
Pipe 3.Described support 1 includes horizontally disposed base plate and vertical support bar on base plate, is provided with one even on this support bar
Connect frame, described link and support bar are slidably connected, and can fix with support bar；When being embodied as, on described support bar vertically
It is provided with a bar hole, described link is connected with support bar by a fastening bolt passing through bar hole, makes to move down on link
Dynamic and fixation is convenient, quick.
Described water collector 2 is fixedly connected with link, and one end of described mozzle 3 is connected with water collector 2；For making water conservancy diversion
More preferably, described mozzle 3 is connected effect with the bottom of water collector 2.It is provided with a warning line 5 in the outside level of water collector 2, its
In, the distance between this warning line 5 and water collector 2 bottom axle envelope 8 lower surface and bearing body 7 and pump shaft between and water storage tank bottom
