Description
Technical field
The utility model belongs to oil return operating device technical field, is related to a kind of flooded evaporator oil return apparatus, utilizes
The ejector action principle of injector, the oil return operation of the vaporizer side for freon flooded screw water cooler.
Background technique
Screw water cooling machine set mostly uses greatly freon refrigerant, since freon dissolves each other to a certain extent with lubricating oil, i.e.,
Just the centrifugation for passing through oil eliminator still has a small amount of lubricating oil in the form of oil mist particles with compressor air-discharging, enters
It accumulates in full liquid evaporator and constantly, it is final in freon refrigerant ullage since lubrication oil density is less than freon
Form lube layer.
If the lubricating oil in evaporator cannot be effectively recycled in compressor, heat transfer efficiency, extreme feelings can be seriously affected
Even running gear is caused to lack lubrication under condition, influences compressor normal operation.
The problem of oil return for how solving flooded evaporator is to guarantee the reliable key technology of water cooler overall operation.
Utility model content
To solve the above problems, the utility model provides a kind of flooded evaporator oil return apparatus, injector is mainly utilized
Ejector action principle, injector upper entrance connect compressor refrigerant exhaust, lower part outlet introduce compressor refrigerant air-breathing,
Middle part trunnion position access evaporator takes oil drop.
The technical solution of the utility model includes:
A kind of flooded evaporator oil return apparatus, mainly by oil return injector 1, liquid-sighting glass 2, shut-off valve 3, connecting tube 4, put
Oily device 5 and fuel outlet valve 6 form；
The oil return injector 1, upper part entrance connect compressor refrigerant exhaust, and lower part outlet connects compressor refrigerant
Air-breathing, middle part trunnion position are connected by connecting tube 4 with the top for device 5 of draining the oil；Between oil return injector 1 and device 5 of draining the oil
Connecting tube 4 is equipped with shut-off valve 3, and shut-off valve 3 is for adjusting oil return rate and truncation drainback passage；
Liquid-sighting glass 2 is installed, for observing liquid condition in the connecting tube 4 between the oil return injector 1 and shut-off valve 3
Variation, when carrying out oil return operation, is observed by the form on liquid-sighting glass 2；
The device 5 of draining the oil, plays lubricating oil surge tank, and the tank body for device 5 of draining the oil passes through about more parallelly distribute ons
Connecting tube 4 respectively oil drop is taken to be connected on flooded evaporator shell, take oil drop along the vertical of flooded evaporator shell
Direction arrangement is equipped with fuel outlet valve 6 positioned at 4 end of connecting tube taken at oil drop.
The liquid-sighting glass 2 is connect with connecting tube 4 by fine weldering mode, remaining each component passes through flared fitting mode
Connection.
The material of the connecting tube 4 is copper.
The utility model has the beneficial effects that the device of the utility model is easy, reliable performance.
Detailed description of the invention
Fig. 1 is a kind of connection schematic diagram of flooded evaporator oil return apparatus.
In figure: 1 oil return injector；2 liquid-sighting glass；3 shut-off valves；4 connecting tubes；5 drain the oil device；6 fuel outlet valves；A, b, c take oil drop.
Specific embodiment
Below in conjunction with attached drawing and technical solution, specific embodiment of the present utility model is further illustrated.
As shown in Figure 1, a kind of flooded evaporator oil return apparatus, mainly by oil return injector 1, liquid-sighting glass 2, shut-off valve 3,
Connecting tube 4, drain the oil device 5 and the composition of fuel outlet valve 6.
In addition to liquid-sighting glass 2 is connect with connecting tube 4 by fine weldering mode, pass through flared fitting mode between remaining each component
Connection.
1 upper entrance of oil return injector connects compressor refrigerant exhaust, and lower part outlet connects compressor refrigerant air-breathing, middle part
Trunnion position access evaporator respectively takes oil drop.
Liquid-sighting glass 2 has the function of to observe liquid condition variation, when carrying out oil return operation, can be seen by upper form
It examines.
Shut-off valve 3 has the function of to adjust oil return rate and drainback passage is truncated.
Device 5 of draining the oil has the function of lubricating oil surge tank.
Vertical Square sets up a, b, c on flooded evaporator shell, and 3 take oil drop, is between each taking oil drop vertical
50mm, horizontal space 75mm.Setting principle are as follows: middle oil-taking point is flushed with refrigerant level control line.Each take at oil drop
It is respectively provided with independently operable fuel outlet valve 6.
Oil return operation before, successively open oil return injector 1 forward and backward shut-off valve (be located at compressor air suction filter,
Gas exhaust piping), shut-off valve 3 selects choosing and suitably taking oil drop (a, b, c), open and put accordingly according to the practical oil reservoir position of evaporator
Oil valve 6 carries out oil return operation.Changed according to liquid in liquid-sighting glass 2, close fuel outlet valve 6 in due course, terminates oil return operation.
