Description
Technical Field
The utility model relates to a mechanical lubrication technical field especially relates to a lubricating grease low oil level detection device.
Background
According to the conventional low oil level detection structure principle, a microswitch in the liquid level detection box is triggered by pressure generated by the depth of an oil level. When lubricating grease is more in the oil drum, the pressure that the degree of depth of liquid level detection box department produced can press the micro-gap switch in the liquid level detection box, make micro-gap switch be in the closed condition always, the electric cabinet detects there is the grease, but lubricating grease consumes totally in the oil drum, when the oil level is not enough, the pressure that the liquid level detection box received disappears, micro-gap switch can bounce, the circuit is opened, the electric cabinet detects the low signal of oil level, the operation of electric cabinet meeting automatic disconnection lubricating pump afterwards, avoid lubricating pump in the oil drum do not have the long-time idle running under the condition of lubricating grease.
By adopting the detection principle, the lubricating grease is high in consistency and easy to adhere to the liquid level detection box, so that a microswitch in the liquid level detection box cannot be normally bounced, the false alarm fault of a low liquid level system is caused, and the lubricating grease cannot be timely supplemented.
SUMMERY OF THE UTILITY MODEL
The utility model aims at not enough among the above-mentioned background art, provide a lubricating grease low oil level detection device to solve among the prior art lubricating grease low oil level and detect coarse technical problem.
In order to achieve the above purpose, the utility model adopts the following technical scheme:
a lubricating grease low oil level detection device comprises a filter block and a dry oil distributor, wherein the filter block comprises a shell and a filter element in threaded connection with the shell, the shell is provided with an oil inlet and an oil outlet, and the oil inlet is communicated with the filter element; the oil outlet is connected with the dry oil distributor through an oil pipe, and one end of one of the pistons in the dry oil distributor is provided with a Hall switch.
Compared with the prior art, the utility model discloses following beneficial effect has:
the utility model provides a lubricating grease low oil level detection device, it is according to the principle of single line progressive distributor, when lubricating grease has normally been beaten oil to the lubricating pump, and when lubricating grease passed through the distributor, the piston of distributor inner chamber can reciprocating motion, installs hall switch at the side of piston in the distributor, whether the piston in detecting the distributor through hall switch is in the motion state judges whether lubricating grease has in the oil drum; when there is not lubricating grease in the lubricating pump oil drum, the distributor just can not have lubricating grease to pass through, and the piston also can not move, and the electric cabinet will detect and does not have lubricating grease in the lubricating pump, and the suggestion hangs down the oil level and reports to the police, and this detection principle compares with the monitoring point principle among the prior art, and the degree of accuracy is higher, and the error is littleer.

FIG. 2 is a perspective view of a filter block in a preferred embodiment of the invention;
fig. 3 is a schematic diagram of the explosion structure of the present invention.
Detailed Description
The technical solution of the present invention will be further explained with reference to the accompanying drawings and embodiments.
As shown in fig. 1-3, as a preferred embodiment, the utility model provides a lubricating grease low oil level detection device, which comprises a filter block 10 and a dry oil distributor 20, wherein the filter block 10 comprises a housing 11 and a filter element 12 screwed on the housing 11, the housing 11 is provided with an oil inlet 13 and an oil outlet 14, and the oil inlet 13 is communicated with the filter element 12; the oil outlet 14 is connected with the dry oil distributor 20 through an oil pipe, and at least one end of each piston in the dry oil distributor 20 is provided with a Hall switch; the dry oil distributor 20 is a single-line progressive distributor; the oil inlet 13 and the oil outlet 14 are threaded interfaces; the dry oil distributor 20 is detachably connected to the top of the filter block 10.
The detection principle of the scheme is as follows: according to the principle of the single-line progressive distributor, when lubricating grease is normally pumped by a lubricating pump, when the lubricating grease passes through the distributor, the piston in the inner cavity of the distributor can reciprocate, a Hall switch is arranged at the side end of one piston in the distributor, and whether the piston in the distributor is in a motion state is detected through the Hall switch to judge whether the lubricating grease exists in an oil drum. When lubricating grease is not in the oil barrel of the lubricating pump, the distributor cannot allow the lubricating grease to pass through, the piston cannot move, the electric cabinet can detect that the lubricating grease is not in the lubricating pump, and the low oil level alarm is prompted.
Preferably, the bottom of the filter block 10 is detachably connected to the bottom plate 30 through a bolt, the bottom plate 30 is provided with a mounting hole 31, and the filter block can be conveniently and quickly fixed and mounted on other components in the system through the bottom plate 30 and the mounting hole 31.
A conventional liquid level detection device and a low liquid level detection device are respectively arranged on two DRB-120P lubricating pumps with the same model for testing:
through above experimental data, it has multiple trouble to discover that conventional low liquid level detection device exists:
typical failure 1: and a lot of lubricating grease in the oil drum can give an alarm at a low liquid level.
Reason analysis: lubricating grease is not conventional liquid medium, and the consistency is higher, has certain stickness moreover, can drag the film of low liquid level detection box when the liquid level has the subsidence, makes the micro-gap switch who detects in the detection box bounce, causes low liquid level wrong report, and the lubricant pump can't be opened.
Typical failure 2: the oil drum is not provided with lubricating grease, but has low liquid level without alarm.
Reason analysis: because the consistency of the lubricating grease is high, sometimes the lubricating grease is agglomerated and adhered to the surface of the film of the low-oil-level box, so that the microswitch cannot be normally bounced; after lubricating grease in the oil drum is consumed, the electric control box does not obtain a low liquid level signal, so that the lubricating pump runs in an idle mode all the time, and the service life of the lubricating pump is shortened.
The low oil level detection device disclosed by the invention is verified through multiple tests that the lubricating grease in the oil drum can automatically stop running under the condition of no lubricating grease, and the phenomenon of misinformation of the low oil level is avoided.
Finally, although the present invention has been described in detail with reference to the preferred embodiments, it should be understood by those skilled in the art that the present invention can be modified or replaced by other means without departing from the spirit and scope of the present invention, which should be construed as limited only by the appended claims.
