Detailed description of the invention
Fig. 1 is the structural schematic diagram of air conditioning pipe system according to the present invention；
Fig. 2 is the structural schematic diagram of oiling device according to the present invention.
Specific embodiment
As shown in Figure 1, air conditioning pipe system of the invention include oiling section 1, it is oil eliminator 2, gas-liquid separator 3, true
Sky pump 4 and corresponding connecting line.In Fig. 1, A is oiling point, and B, C are respectively oil filling pipeline and oil eliminator 2 and gas-liquid
The junction of separator 3.Specifically, referring to fig. 2, oiling section 1 includes triple valve 11, solenoid valve 12, pump nozzle 13, filter
14 and corresponding connecting line.Preferably, pipeline uses copper pipe.
Specifically, in the air-conditioning duct each component positional relationship are as follows: oiling section 1 is located at oil eliminator 2 and gas-liquid point
From between device 3, the vacuum pump 4 is between the oil eliminator 2 and the gas-liquid separator 3, the gas-liquid separator 3
Between the vacuum pump 4 and the oiling section 1, the oil eliminator 2 is located at the vacuum pump 4 and the oiling section 1
Between.Oiling point is set on the oiling section, and when oiling injects the ratio of the gas-liquid separator and the oil eliminator
Corresponding to the ratio between the gas-liquid separator and the volume of the oil eliminator.
The positional relationship of all parts of the oiling section are as follows: solenoid valve 12 is located at the triple valve 11 and the gas-liquid point
From between device 3, filter 14 is between the oil eliminator 2 and the triple valve 11.
In the selection of the position of oiling point A, it is preferably chosen near solenoid valve 12.When carrying out oiling, electromagnetism is opened
Valve, oil eliminator 2, gas-liquid separator 3 are evacuated under the action of vacuum pump 4 and oil gun pressurizes in A point, total in positive/negative pressure
Under same-action, refrigeration oil is infused arrive oil eliminator 2, gas-liquid separator 3 simultaneously.
In a preferred embodiment, internal diameter D1 ∈ [4,6] mm of pipeline, preferred value D=4.8mm, the choosing of specific value
Practical structures are taken to determine according to situation；Solenoid valve 12 is for balancing height pressure pressure in system operation, it is to freezing oil stream when oiling
Certain resistance is moved, preferably its diameter D2=1.9mm；Pump nozzle preferably uses needle-valve, specification be diameter D3 ∈ [6.35,
9.53] mm, preferably 3=7.94mm；14 specification of filter is D4 ∈ [10,25] mm, preferably D4=19mm.
Position to the oiling point of pipeline is by being calculated as follows:
Pipeline the C point joined from oiling point A to gas-liquid separator 3 is known as gas-liquid separator bypass pipe, it will
The pipeline B point joined from oiling point A to oil eliminator 2 is known as oil eliminator bypass pipe, by whole gas-liquid separator
The diameter of siphunculus is D1, and the diameter of solenoid valve 12 is D2, in specific but non-limiting embodiment, D1=4.8mm, and
The diameter D2=1.9mm of solenoid valve 12, therefore will cause resistance in oiling.If making because resistance coefficient is k caused by solenoid valve
D1=k*D2mm (k ∈ (1,2), preferred value 1.5).
Obtaining the oily speed in pipe by Reynold's equation is
V=Re μ/ρ d
Wherein, V is flow velocity, and Re Reynolds number, μ is viscosity coefficient, and d is equivalent diameter, and ρ is density.
Therefore, the speed V of oil note oil inlet separator bypass pipe1With the speed V of gas-liquid separator bypass pipe2The ratio between: V1: V2
=d2: d1, and because of the flow Q=SV=(D/2) of oil2π V, and D1=1.5*D2 substitute into above formula, obtain Q1:Q2=3:2.
By factory total injected fuel quantity 4L, 5L, 5.5L conversion, oil mass is respectively 2.4L, 3L, 3.3L, oiling point in oil eliminator
Maximum oiling just fills oil eliminator, therefore the oiling is feasible.
Due to caliber D1=4.8mm, length L < 1m, therefore, when oiling because caused by copper pipe droop loss can ignore not
Meter.Gravity influences at the small change of consideration pipeline and oiling, and setting oiling point A is solenoid valve to first horizontal position of C point,
From solenoid valve distance l ∈ (0,90) mm (see Fig. 2).
Production practical operation oiling verifying is carried out to above-mentioned design, solenoid valve is opened and is then produced with machine vacuum outside vacuum pumping
It is quasi- oiling point practical operation oiling on line, before the quasi- oiling point perfusion of record, oil gas minute oil mass changes after perfusion, after analyzing solenoid valve
Oil oil accounting, obtains following table.
It is above-mentioned statistics indicate that, first, second and third wheel respectively oiling 4L, 4L, 5.5L, solenoid valve branch rood oil ratio about 40%.
Therefore the oiling is feasible.
The above, only presently preferred embodiments of the present invention not do limitation in any form to the present invention.It is any ripe
