Specific embodiment
The embodiments of the present invention is described further with reference to the accompanying drawing.
The specific embodiment of the centrifugal pump of the utility model: centrifugal pump includes grease-box, is installed on grease-box useful
In the liquid level observing device of height of liquid level in observation grease-box.As shown in Fig. 2, liquid level observing device includes that transparent liquid level is seen
Test tube 3, liquid level observing pipe 3 is vertically arranged, and liquid level observing pipe 3 has the lubricant oil cavity 31 for accommodating lubricating oil.Liquid level
The interface being connected to grease-box is equipped on the side wall of sighting tube 3 in lower part, interface is equipped with double end threaded joint 4.Bipitch silk
Buckle joint 4 includes the thread segment 41 in both ends and the spanner lever piece 42 between two thread segments 41, in two thread segments 41
One of them be threadedly coupled with liquid level observing pipe 3, another is threadedly coupled with grease-box.Spanner lever piece 42 is convenient for worker
Double end threaded joint 4 is screwed by spanner.3 upper end tube nozzle of liquid level observing pipe, which is constituted, to be entered for hairbrush to clean liquid level sighting tube 3
The access hole of inner wall is equipped with dust cap 5 at access hole.It is equipped with internal screw thread at access hole, there is boss 51, boss on dust cap 5
51 are equipped with the external screw thread with screw-internal thread fit at access hole.It can be avoided dust etc in environment by the way that dust cap 5 is arranged
Substance enters in liquid level observing pipe 3 and being attached on 3 inner wall of liquid level observing pipe causes to influence to observe, and avoids influencing quality of lubricating oil
Amount.It is additionally provided on liquid level observing pipe 3 for being connected to the extraneous pressure compensation opening 6 with lubricant oil cavity 31.
Liquid level observing pipe and dust cap are process by transparent plastic.Double end threaded joint is cylinder, by metal material
Matter is process, and in use process, oil liquid may shake, and double end threaded joint is located at position near grease-box outside
There are stress concentration phenomenons at place, it is therefore desirable to guarantee that double end threaded joint has certain structural strength, there can be no fractures, double
Captacula buckle joint can satisfy intensity requirement using metal material, avoid the occurrence of fracture.Specifically using steel in the present embodiment.
It is of course also possible to use other metals such as iron, copper.
When field application, first double end threaded joint is connected on grease-box, is then again connected to liquid level observing pipe
On double end threaded joint, dust cap is finally tightened to liquid level observing pipe top.It is of course also possible to which dust cap is first tightened to liquid
On the sighting tube of position, then it will be integrally connected on double end threaded joint both as one again.Lubricating oil in grease-box is logical
Cross double end threaded joint enter liquid level observing pipe lubricant oil it is intracavitary, oil level height can be understood by liquid level observing pipe in time
Low and then grasp centrifugal pump lubrication circumstances.When liquid level observing inside pipe wall, which is attached with lube contamination, does not see liquid level, it is only necessary to
Dust cap is opened, can easily be cleaned out liquid level observing inside pipe wall with tools such as hairbrush, without termination of pumping and emptying lubrication
