Abstract
The utility model discloses an oil supply system of a parallel screw machine, which belongs to the field of the refrigeration device. The oil supply system comprises oil content connected with the exhaust pipe of a compressor, the oil content is connected with a one-way valve through a stop valve I and a filter, the one-way valve is connected with an oil cooler through a stop valve III, the output pipeline of the filter is connected with a stop valve IV, the stop valve IV is connected with a stop valve VI through a scroll compressor, the stop valve VI is connected with the output pipeline of the one-way valve through an oil reservoir, and the scroll compressor is connected with the exhaust pipe of the compressor through a stop valve V. Since the scroll compressor and the oil reservoir are used to replace the oil pump, the utility model solves the problem of oil leakage. Moreover, the whole oil supply system has the advantages of stable operation and good performance.
Description
Technical field
The utility model belongs to the refrigeration plant field, is specifically related to a kind of oil supply system.
Background technique
As shown in Figure 1, the helical-lobe compressor oil supply system comprises oil separator 1 in the prior art, oil separator 1, stop valve I 2, filter 3, one-way valve 4, stop valve III 10, oil cooler 8 and water pump 9 are connected successively, and stop valve III 5 connects the compressor oil-supplying pipeline; Pressure difference valve 6 in parallel and oil pump 7 on the one-way valve 4.When the pressure reduction of the high pressure of unit and low pressure was not also set up, the oil of oil content 1 the inside was supplied with compressor then by stop valve I 2, filter 3, oil pump 7, stop valve III 10, oil cooler 8, stop valve II 5; Set up when setting pressure reduction when the high pressure of unit and low pressure, the oil of oil content 1 the inside is supplied with compressor then by stop valve I 2, filter 3, one-way valve 4, stop valve III 10, oil cooler 8, stop valve II 5.Used oil pump 7 in the working procedure, yet existing problem is that oil pump 7 leakage phenomenon are serious, the refrigeration system valve member is too much, complex structure, job insecurity.
The model utility content
To be solved in the utility model is the problem that the oil pump leakage of oil causes the oil supply system job insecurity, and a kind of oil supply system of oil-proof, simple in structure, working stability is provided.
The technical solution of the utility model realizes with following method:
A kind of oil supply system, comprise the oil content that links to each other with compressor exhaust pipe, oil content connects one-way valve by stop valve I, filter, one-way valve connects oil cooler by stop valve III, the output pipe of filter connects stop valve IV, stop valve IV connects stop valve VI by scroll compressor, and stop valve VI connects the output pipe of one-way valve by oil conservator; Scroll compressor connects compressor exhaust pipe by stop valve V.
Described oil cooler is the water-cooling type oil cooler, and the water-cooling type oil cooler connects water pump.
Described oil cooler is the Wind-cooling type oil cooler.
In the utility model, replace oil pump, do not have the leakage of oil problem, whole oil supply system working stability, functional with scroll machine and oil conservator.
Description of drawings
Fig. 1 is an oil supply system schematic representation in the prior art;
Fig. 2 is the utility model embodiment 1 a schematic representation;
Fig. 3 is the utility model embodiment 2 a schematic representation.
Embodiment
As shown in Figure 2, the utility model comprises the oil content 1 that links to each other with compressor exhaust pipe, and oil content 1 connects one-way valve 4 by stop valve I 2, filter 3, and one-way valve 4 connects water-cooling type oil cooler 8 by stop valve III 10, and oil cooler 8 connects water pump 9; The output pipe of filter 3 connects stop valve IV 15, and stop valve IV 15 connects stop valve VI 11 by scroll compressor 14, and stop valve VI 11 connects the output pipe of one-way valve 4 by oil conservator 12; Scroll compressor 14 connects compressor exhaust pipe by stop valve V 13.
The utility model working procedure is as follows: when the pressure reduction of the high pressure of compressor and low pressure is not also set up, the oil of oil content 1 the inside by stop valve I 2, filter 3, stop valve IV 15, scroll compressor 14, stop valve VI 11, oil conservator 12, stop valve II 10, oil cooler 8 to the compressor oiler.In this process, force fuel feeding by scroll compressor 14, scroll compressor 14 sucks lower amount of refrigerant by stop valve V 13 from the compressor air-discharging pipeline, has guaranteed the normal pump oil of scroll compressor.After the high low pressure pressure reduction of compressor was set up, the oil of oil content 1 the inside arrived the compressor oiler by stop valve I 2, filter 3, one-way valve 4, stop valve III10, oil cooler 8.
Described oil cooler is a Wind-cooling type oil cooler 16, and other structure is with embodiment 1.
