Abstract
The utility model relates to a split intelligent lubricating and cooling system for a bearing, and in particular relates to a lubricating and cooling system for a large-scale under-deck excavating pump bearing box. The split intelligent lubricating and cooling system comprises a gear pump, and is characterized in that the gear pump is communicated with an inlet of a cooler through a one-way valve and a double-screen oil filter in sequence, and an outlet of the cooler is communicated with an inlet of a lubricating passage of the excavating pump bearing box through a first temperature sensor, a pressure sensor, a flow transmitter and a throttling valve in sequence; and an outlet of the lubricating passage of the excavating pump bearing box is communicated with an oil tank through an oil return pipe, and a second temperature sensor is arranged on the oil return pipe. The split intelligent lubricating and cooling system adopts a double-oil-pump oil supply system, when one oil pump is damaged, the other oil pump is switched on automatically to perform continuous operation; and the oil pumps, the oil filter, the cooler, a part of sensors, valve members and the like are integrated in a wall hanging unit, and the oil tank is manufactured into a structural oil tank, so that the floor area is reduced and the split intelligent lubricating and cooling system is convenient to dismount and maintain.
Description
Technical field
The utility model relates to a kind of split type bearing intelligent lubricating and cooling system, especially for the lubricating and cooling system of dredging pump bearing housing in the large-scale cabin.
Background technique
Dredging pump is the maximum dredging pump in present Asia in the large-scale cabin; The bearing unit of the main shaft of big machinery all need be lubricated with lubricant oil like this; Existing lubrication system generally all is to lean on oil pump that the lubricant oil in the fuel tank is pressed into circulation loop; And get into the dredging pump bearing housing it is lubricated, the also lubricated oil of huge heat that dredging pump bearing fast rotational produces is taken away, and therefore lubricant oil can reach than higher temperature oil is degenerated; Therefore need to get into cooler and cool off, flow into the return tube that leads to the slurry pump bearing housing after the cooling again and reuse.
In the existing technology, this cyclic process only is furnished with throttle valve adjustment flow and satisfies fuel feeding, and does not all have device to monitor for the height of oil in the oily temperature of the pressure of the lubricated required assurance of cooling procedure, flow rate of lubricating oil, filler opening, oil outlet and the fuel tank.
The model utility content
The utility model technical issues that need to address provide a kind of split type bearing intelligent lubricating and cooling system, make in the large-scale cabin dredging pump lubricating and cooling system form and performance more perfect.
For solving the problems of the technologies described above, the technological scheme that the utility model adopted is:
The utility model comprises gear pump; Gear pump is communicated with the import of cooler successively through one-way valve, two net oil purifier, the outlet of cooler is communicated with the lubricated road import of dredging pump bearing housing successively through temperature transducer one, pressure transducer, flow transmitter and throttle valve;
The lubricated road outlet of dredging pump bearing housing is communicated with fuel tank through return tube, and temperature transducer two is set on the return tube;
Between said one-way valve and the two net oil purifier relief valve one is set, between cooler and the temperature transducer one relief valve two is set.
The further improvement of the utility model is:
Said gear pump parallel connection is provided with two.
Said fuel tank is an enclosed construction, and air-strainer is installed at the top, and fuel outlet is established in the bottom, and the fuel tank inner chamber is provided with level meter, and intracavity bottom is provided with heating pipe.
Said fuel tank is the structure fuel tank, promptly directly reserves as fuel tank in the appropriate location of cabin, connects through flexible pipe again, has so promptly reduced floor space and has been convenient to open and inspect maintenance again.
Element such as said gear pump, one-way valve, two net oil purifier, cooler, temperature transducer one, pressure transducer, flow transmitter and throttle valve and connecting pipe thereof integrate and form integrated lubrication unit.
Because the technological progress of having adopted technique scheme, the utility model to obtain is:
1, the utility model adopts two oil pump feed systems, after a table oil pump damages, can automatically switch to another table oil pump and carry out non-stop run.
2, the sensing device that is provided with in the circulation loop can reflect current operational situation in good time, when appearance is unusual, reports to the police at once.
3, because the specific (special) requirements of dredger itself is to reduce floor space as far as possible; Split type bearing intelligent lubricating and cooling system comprises that oil pump, oil purifier, cooler, operative sensor and valve member etc. are integrated in the wall hanging unit; And fuel tank is made the structure fuel tank; Promptly directly reserve as fuel tank, connect through flexible pipe again, so promptly reduced floor space and be convenient to open and inspect maintenance again in the appropriate location of cabin.
