Abstract
The utility model discloses an exterior oil way system for a centrifugal refrigerating compressor, which comprises a gear case, an oil pump, an oil filter, an oil cooler and a bearing lubricating oil way. The oil way system is characterized in that the oil way system further comprises an elevated oil tank which is located behind the oil cooler, before the bearing lubricating oil way and at the upper part of the gear case. The oil filter and the oil cooler are disposed outside the gear case; one end of the oil filter is connected with the oil pump through a first stop valve; and the other end of the oil filter is sequentially connected with the oil cooler and the elevated oil tank. The elevated oil tank of the oil way system can avoid damage of the bearing. Stop valves are respectively added in front of and behind the oil filter, so when the compressor is shut down, after the stop valves at the two sides are closed, the oil filter can be replaced without sucking out the refrigerant in the compressor, thereby not only reducing the work intensity of the operator but also reducing the operating cost of the compressor. The exterior oil filter and the oil cooler greatly reduce the structural complexity of the gear case and enable the gear case to be easier to process, thus reducing making cost.
Description
Technical field
The utility model relates to the external oil-way system of a kind of centrifugal refigerating compressor, particularly a kind of centrifugal refigerating compressor.
Background technique
Because the bearing position at pinion shaft and motor shaft place and big pinion place all need oil to be lubricated and cool off, playing the rigid support of rotary component and to take away the heat that produces because of high speed rotating, so that oil-way system just seems in unit running process is particularly important.
Common oil-way system generally is made up of the oil cooler (or oil cooler), oil circuit filtrating equipment (or oil strainer), the oily power supply device (or oil pump) that are built in the gear-box, this built-in oil cooler and oil strainer make that the structure of gear-box is quite complicated, refrigeration agent need be extracted out when also making the periodic replacement oil strainer, this situation has strengthened operator's working strength, has improved the operating cost of unit; And, when the unit accident power-off,, oil pump stops the conveying of oil owing to shutting down, and rotor but also can continue to rotate a period of time because of inertia, and at this moment, bearing very easily is damaged under unlubricated oily situation.
The model utility content
The purpose of this utility model aim to provide that a kind of simple and reasonable, bearing long service life, the safety rate height of system, oil strainer are easy to change and still can be when rotor be because of the inertia rotation after oil pump shuts down to the external oil-way system of the centrifugal refigerating compressor of bearing fuel feeding, to overcome deficiency of the prior art.
Press the external oil-way system of a kind of centrifugal refigerating compressor of this purpose design, comprise gear-box, oil pump, oil strainer, oil cooler and bearing lubricating oil circuit, it is characterized in that also comprising top petrol tank, top petrol tank is positioned at after the oil cooler, before the bearing lubricating oil circuit, and place the top of gear-box; Oil strainer and oil cooler place outside the gear-box; One end of oil strainer joins by first stop valve and oil pump, and the other end of oil strainer joins with oil cooler and top petrol tank successively, is provided with second stop valve between oil strainer and the top petrol tank.
Described second stop valve is arranged between oil strainer and the oil cooler, and perhaps, second stop valve is arranged between oil cooler and the top petrol tank.
Described oil pump places the bottom of gear-box.
The utility model is owing to be arranged on top petrol tank on the top of gear-box, so when unexpected the power failure, though oil pump shuts down, but the lubricant oil that stores in the top petrol tank flows in the bearing lubricating oil circuit because of action of gravity, thereby guaranteed in motor stops the rotation fore bearing, also to have lubricant oil that it is cooled off and lubricates, avoid damage of bearings, prolong the working life of bearing.Front and back at oil strainer have increased stop valve respectively, when unit shuts down, turn-off the stop valve of both sides and can change oil strainer, need not to extract the refrigeration agent in the unit, it had both reduced operator's working strength, had reduced the operating cost of unit again.
It is external that the utility model changes traditional built-in oil strainer and oil cooler into, is about to oil strainer and oil cooler and places outside the gear-box, greatly reduces the complexity of gear box structure, is convenient to the casting processing of gear-box, has reduced fabricating cost.It is applicable to air conditioner refrigerating and industry cooling oil circuit cooling, filtration and the anti-involuntary stoppage protection etc. of centrifugal refigerating compressor.
Description of drawings
Fig. 1 is the utility model one example structure schematic representation.
Among the figure: 1 is gear-box, and 2 is oil pump, and 3 is first stop valve, and 4 is oil strainer, and 5 is oil cooler, and 6 is second stop valve, and 7 is top petrol tank, and 8 is bearing lubricating oil circuit.
Embodiment
Below in conjunction with drawings and Examples the utility model is further described.
Referring to Fig. 1, the external oil-way system of this centrifugal refigerating compressor, comprise gear-box 1, oil pump 2, first stop valve 3, oil strainer 4, oil cooler 5, second stop valve 6, top petrol tank 7 and bearing lubricating oil circuit 8, wherein, oil strainer 4 and oil cooler 5 place outside the gear-box 1, oil pump 2 is installed in the bottom of gear-box 1, top petrol tank 7 is arranged on the top of gear-box 1, and oil pump 2, first stop valve 3, oil strainer 4, oil cooler 5, second stop valve 6, top petrol tank 7 link to each other successively with bearing lubricating oil circuit 8.
Top petrol tank 7 is positioned at after the oil cooler 5, before the bearing lubricating oil circuit 8.One end of oil strainer 4 joins with oil pump 2 by first stop valve 3, and the other end of oil strainer 4 joins with oil cooler 5 and top petrol tank 7 successively, and second stop valve 6 is provided with between oil cooler 5 and the top petrol tank 7.
