In order to solve the reliable oily equilibrium problem of multi-joint compressor, a kind of mode is at least two compressors adopting parallel way to connect, and is connected to a kind of oil balancing device respectively by the air entry of every compressor and equal hydraulic fluid port.Although can realize oil mass dynamic equilibrium between all compressors, the complex structure of device, the installation site of pipeline component requires high.
Also have a kind of mode to be a kind of multi-joint compressor oil inside offering oil balanced structure, oil balance tube is in compression case external body, and one end is connected to the oil sump of compressor cavity, and the other end is connected to the exhaust high-pressure side of compressor cavity.This structure increases the perforate on a compressor housing and the perforate on a blast pipe, and welding procedure etc., add the complexity of compression mechanism fabrication technique.
Utility model content
For solving the problem, the utility model provides a kind of multi-joint compressor oil balanced structure, and it is simply clean and tidy that it has outward appearance, and user installation takes up room little, easy to use and guarantee that multi-joint compressor operating is safe and reliable, the feature that persistence is long.Overcome structure and the installation pipeline of existing oil balancing device complexity, the oil outer balance pipe simultaneously solving oil inside offering oil balance causes the problem of compressor external structure complexity.
The utility model solves the technical scheme that its technical problem adopts: a kind of multi-joint compressor oil balanced structure, comprise the closure casing that is provided with air intake duct and blast pipe and be contained in and determine scroll plate and baffle plate in described closure casing, described closure casing is being determined to form exhaust chamber above scroll plate, accumulator is formed in the below of baffle plate, determining to form motor room between scroll plate and baffle plate, describedly determine the suction end of scroll plate and described air intake duct conducting, outside the exhaust outlet determining scroll plate, kuppe is housed, described kuppe and determine to form high pressure chest between scroll plate, determine the through hole that scroll plate is provided with high pressure chest and motor room described in some conductings, described closure casing is built with the oil balance tube of accumulator described in conducting and exhaust chamber.
Be further used as the improvement of technical solutions of the utility model, describedly determine scroll plate and be provided with oil guiding hole, one end of described oil balance tube is connected to determines oil guiding hole in scroll plate, and the other end is connected to accumulator by baffle plate.
The beneficial effects of the utility model: this multi-joint compressor oil balanced structure, in compressor operation, cold-producing medium is drawn in compressor means portion working chamber by air intake duct, compressedly be discharged to determine in high pressure chest that the scroll plate back side and kuppe formed from determining scroll plate exhaust end, in this high pressure chest, gas pressure is P1.Compressed Gas is discharged in motor room through each through hole at the edge determining scroll plate again, and motor gas pressure inside is P2.Exhaust gas pressure inside is P3.Due to P1 > P2 > P3, higher than the refrigeration oil of baffle plane together with Compressed Gas, enter oil balance tube by the lower end of oil balance tube, upwards enter into exhaust chamber via oil balance tube.Exhaust outlet gas pressure is P4, and due to P3 > P4, the refrigeration oil in exhaust chamber is discharged by blast pipe together with Compressed Gas.Be separated through gas and oil, refrigeration oil flows in other compressors of system parallel connection.
Simultaneously, the utility model also can decide the setting height(from bottom) of baffle plate according to the oil mass of compressor operation actual needs, the position of oil balance tube in compressor, just effectively can control the oil level of accumulator, ensures the minimum fuel that in running, each compressor needs.
It is simply clean and tidy that the utility model has outward appearance, and user installation takes up room little, easy to use and guarantee that multi-joint compressor operating is safe and reliable, the feature that persistence is long.Overcome structure and the installation pipeline of existing oil balancing device complexity, the oil outer balance pipe simultaneously solving oil inside offering oil balance causes the problem of compressor external structure complexity.
Accompanying drawing explanation
Below in conjunction with accompanying drawing, the utility model is described in further detail:
Fig. 1 is the utility model example structure schematic diagram.
Detailed description of the invention
With reference to Fig. 1, the utility model provides a kind of multi-joint compressor oil balanced structure, comprise the closure casing 9 that is provided with air intake duct 11 and blast pipe 1 and be contained in and determine scroll plate 10 and baffle plate 7 in described closure casing 9, described closure casing 9 is being determined to form exhaust chamber 2 above scroll plate 10, accumulator 6 is formed in the below of baffle plate 7, determining to form motor room 8 between scroll plate 10 and baffle plate 7, described suction end and described air intake duct 11 conducting determining scroll plate 10, outside the exhaust outlet determining scroll plate 10, kuppe 3 is housed, described kuppe 3 and determine to form high pressure chest 4 between scroll plate 10, determine the through hole that scroll plate 10 is provided with high pressure chest 4 and motor room 8 described in some conductings, described closure casing 9 is built with the oil balance tube 5 of accumulator described in conducting 6 and exhaust chamber 2.Describedly determine scroll plate 10 and be provided with oil guiding hole, one end of described oil balance tube 5 is connected to determines oil guiding hole in scroll plate 10, and the other end is connected to accumulator 6 by baffle plate 7.
In compressor operation, cold-producing medium is drawn in compressor means portion working chamber by air intake duct 11, is compressedly discharged to determines in high pressure chest 4 that scroll plate 10 back side and kuppe 3 formed from determining scroll plate 10 exhaust end, and in this high pressure chest 4, gas pressure is P1.Compressed Gas is discharged in motor room 8 through each through hole at the edge determining scroll plate 10 again, and in motor room 8, gas pressure is P2.In exhaust chamber 2, gas pressure is P3.Due to P1 > P2 > P3, higher than the refrigeration oil of baffle plate 7 plane together with Compressed Gas, enter oil balance tube 5 by the lower end of oil balance tube 5, upwards enter into exhaust chamber 2 via oil balance tube 5.Blast pipe 1 outlet gas pressure is P4, and due to P3 > P4, the refrigeration oil in exhaust chamber 2 is discharged by blast pipe 1 together with Compressed Gas.Be separated through gas and oil, refrigeration oil flows in other compressors of system parallel connection.
