Abstract
A temperature probe is added on the bearing at the feed end (non-driving end) of a centrifugal sludge dehydration machine to enhance the bearing temperature protection; and the quantitative supplement lubrication time of the lubricating grease of the bearing is determined according to the bearing temperature. By adopting the technology of the invention, the consumption of the lubricating grease can be saved, the workload for artificially supplementing the lubricating grease can be reduced, the work efficiency of the centrifugal sludge dehydration machine can be increased and the waste of resources can be reduced.
Description
Technical fieldThe present invention relates to the sludge dewatering treatment field, specifically relate to the treatment process of sludge dewatering in a kind of PTA device.
Background technologyIn the prior art, centrifugal sludge dewatering equipment in the running, need regularly to replenish the bearing lubrication grease, require per 4 hours supplemental lubrication fat 4 grams in the original equipment, not only need to consume a large amount of lubricating grease, and can not long-term operation equipment, supplemental lubrication fat need constantly stop, not only bothersome effort, and influence working efficiency, cause waste to artificial and resource.
Summary of the inventionIn order to solve the problem that above-mentioned prior art exists, the present invention adopts at centrifugal sludge dewatering equipment feed end (anti-drive end) bearing increases temp probe, increases the bearing temperature protection, determines the bearing lubrication grease quantitative supplemental lubrication time according to bearing temperature.Adopt technology of the present invention, saved the consumption of lubricating grease, reduced the workload of artificial supplementation lubricating grease, improved the working efficiency of centrifugal sludge dewatering equipment, reduced the waste of resource.
In order to solve the problems of the technologies described above, the present invention is achieved through the following technical solutions:
Increase temp probe at centrifugal sludge dewatering equipment feed end (anti-drive end) bearing, increase the bearing temperature protection, determine the bearing lubrication grease quantitative supplemental lubrication time according to bearing temperature.
Can monitor the operating temperature of bearing behind the centrifugal sludge dewatering equipment increase temp probe at any time, be that operation and maintenance personnel clearly judge this bearing running status, original equipment requires per 4 hours supplemental lubrication fat 4 grams, adjust supplemental lubrication fat mode after increasing temp probe, when bearing temperature is per 8 hours supplemental lubrication fat 4 grams below 50 degree, bearing temperature is normal operating condition at 50～65 degree, bearing temperature 65 degree are above to need monitoring to move, the above friendship maintenance of equipment personnel maintenance that needs to stop of bearing temperature 90 degree; Adjust to significantly reduce after the lubricating grease arbitrary way and mend the fat frequency and prolong bearing work-ing life, the long life of former benefit fat mode bearing is 2 months, can use after the change 4～6 months; Former per 4 hours supplemental lubrication fat 4 grams, adjust mend after the fat mode replenished in about 48 hours 4 can, can save a large amount of lubricating grease.
Increase in the temp probe synoptic diagram at the centrifugal sludge dewatering equipment feed end of Fig. 1 bearing, the major parts of structure of the present invention comprises temp probe, fitting nut, bearing outer ring, bearing inner race, feed end bearing support, fastening screw keyhole, main shaft; Temp probe inserts feed end bearing support inside, by being threaded, and fixes with fitting nut, prevents that temp probe is shifted because of vibration equipment, prevents that thermometric error is bigger; The outside surface of temp probe and bearing outer ring need leave certain interval (gap length needs to select for use the form fixed according to probe), and temp probe and the bearing outside surface gap domestic demand high temperature resistant lubricating grease of annotating makes bearing temperature can better reach temp probe; Bearing is completely fixed on the feed end bearing support, and axial float is located with bearing gland, and bearing inner race is fixed on the rotating spindle, and axial float is fixed with fitting nut; The feed end bearing support is also locked on equipment supporter by the fastening screw keyhole with bolting.Two kinds of temp probe selectable electronic that the present invention adopts or thermal expansions.
The remarkable beneficial effect that the present invention has is: adopt technology of the present invention, saved the consumption of lubricating grease, reduced the workload of artificial supplementation lubricating grease, improved the working efficiency of centrifugal sludge dewatering equipment, reduced the waste of resource.
