Abstract
The utility model discloses a kind of refrigerator car refrigeration unit oil-returning structure, including compressor, condenser, evaporator, gs-oil separator, return line, the gs-oil separator is outer throttle type gs-oil separator, the return line is oil return capillary, one end of this oil return capillary is connected with the outlet of outer throttle type gs-oil separator, and the other end connects with the oil return opening of compressor or the pouring orifice of compressor.The utility model has the advantages of compressor does not produce locking damage and oil return efficiency high compared with the prior art.
Description
Technical field
A kind of Refrigeration Technique is the utility model is related to, particularly a kind of refrigerator car refrigeration unit oil-returning structure.
Background technology
The oil-returning structure of existing refrigerating machine of refrigerated truck group is set using interior throttle type oil eliminator and return line structure, oil return opening
In the return line of evaporator outlet or compressor air suction pipeline front end, following defects be present in this oil-returning structure：Compression
The compressed machine inhaling hose arrangement of sump recirculating oil quantity and effect length are larger, are less than -7 DEG C in the temperature inside the box, compressor rotary speed
During more than 2000 revs/min, freezing oil viscosity increase, oil return effect drastically deteriorates, and causes compressor abrasion to produce abnormal sound or even embrace
Dead damage；Blocking is wherein not easy to judge, a whole set of can only changed；Oil return ratio is relatively low.
The content of the invention
The purpose of this utility model is to provide a kind of compressor and does not produce locking damage and a kind of refrigeration of oil return efficiency high
Vehicular refrigeration unit oil-returning structure.
The technical solution of the utility model is, including compressor, condenser, evaporator, gs-oil separator, return line,
It is characterized in that：The gs-oil separator is outer throttle type gs-oil separator, and the return line is oil return capillary, this oil return
One end of capillary is connected with the outlet of outer throttle type gs-oil separator, the note of the oil return opening or compressor of the other end and compressor
Hydraulic fluid port connects.
The utility model has the advantages of compressor does not produce locking damage and oil return efficiency high compared with the prior art.
Brief description of the drawings
Fig. 1 is the oil-returning structure schematic diagram of existing refrigerating machine of refrigerated truck group；Fig. 2 is structure principle chart of the present utility model.
Embodiment
In order to solve the defects of prior art is present, the utility model uses technical scheme as shown in Figure 2, and this practicality is newly
Type uses outer throttle type gs-oil separator 2, and return line uses oil return capillary 7, to compressor 1, exhaust hose 3, condenser
4th, water influent pipeline 5, defroster duct 6, inhaling hose 8, oil return opening 9, evaporator 10 do not change.
Operation principle of the present utility model, the compressor and freeze oil of system is entered with compressor air-discharging, through outer throttle type oil
The oil that gas separating device is separated injects oil return opening 9 by oil return capillary 7 and returned in oiling compressor groove, or by capillary
Returned into oiling compressor mouth 11 in oiling compressor groove.It is cold that above-mentioned oil-returning structure can come out Oil-gas Separation in system
Frozen oil, it can effectively return to compressor oil groove, it is ensured that compressor normal operation under worst cold case；Compressor oil groove recirculating oil quantity not by
The influence of compressor air suction flexible pipe arrangement；Blocking can be identified the presence or absence of by low pressure oil gas, even if blocking, only need to change
Oil return capillary, changed without whole system；Avoid compressor oil return it is not smooth and cause abrasion even locking damage
It is bad.
