The specific embodiment
Embodiment one (liquid-level switch control oil extraction):
The utility model in actual implementation process, structure as shown in Figure 3, circuit is as shown in Figure 4.Described oil return valve is magnetic valve or motor-driven valve.Described liquid level sensor or liquid-level switch can be Floating Ball Liquid Level sensor or ultrasonic liquid level sensor or float-ball type liquid level control switch.Remove on the preceding described cylindrical shell 3 and set up first oil return valve 9, and outside liquid level sensor or the liquid-level switch, set up one second oil return valve 15 again, the inlet of described first oil return valve 9 links to each other with oil storage zone, cylindrical shell bottom, and outlet links to each other with oil return pipe 13; The inlet of described second oil return valve 15 links to each other with the outlet of ball-cock assembly 8, and outlet links to each other with the one section oil return pipe 16 that increases newly.Cylindrical shell 3 is provided with first oil return valve 9 and second oil return valve 15 is magnetic valve D1, D2, and liquid level sensor 14 is band upper limit A, lower limit B and following lower limit C and spacing adjustable liquid-level switch.This switch output signal is by the Push And Release of two oil return valves of auxiliary reclay KA1, KA2 control, the inlet of described first oil return valve 9 links to each other with oil storage zone, cylindrical shell bottom, outlet links to each other with oil return pipe, the inlet of described second oil return valve 15 links to each other with the outlet of ball-cock assembly 8, and outlet links to each other with the one section oil return pipe that increases newly.When the floating ball rod device of ball-cock assembly 8 is stuck, ball float 6 can not rise, when ball-cock assembly 8 can not be opened, pasta in the cylindrical shell 3 can slowly rise, and when oil level rose to the high position, its upper limit was connected, first magnetic valve begins oil extraction, oil is imported oil return pipe, thereby oil is flowed into the compression crankshaft case, and auxiliary reclay KA2 closes and also self-locking, when oil is discharged to down in limited time, the liquid-level switch lower limit is opened, and stops oil extraction, and auxiliary reclay KA2 opens and resets.If former ball-cock assembly can't be closed, when oil level drop to following in limited time, KA1 gets electric, closes first and second magnetic valves by force.For the ease of observing, can on cylindrical shell, establish liquid-sighting glass 12, observe the height of liquid level by liquid-sighting glass 12, be convenient in time judge whether pasta is normal.Liquid-sighting glass 12 can be provided with the oil level scale, is convenient to judge more clearly whether pasta is normal.
QF1 is breaker (C65N-D10/2P) among the figure, and D1 is first magnetic valve 6, and D2 is second magnetic valve 12 that installs additional behind its former oil exit pipe.KA1, KA2 are auxiliary reclay.
Yet available circuit shown in Figure 5 during simple application does not have downscale protection down, other course of work and aforementioned identical.
Or with shown in Figure 6, with the time relay K T1 control oil extraction time, other course of work and aforementioned identical.
Also can on oil return pipe, set up a hand-operated valve in addition, but when float-controlled valve this magnetic valve of manual-lock can not close the time that is stuck.Avoid high pressure-temperature gas to enter compressor crankcase, cause overheat of compressor.
Embodiment two (time control oil extraction):
As shown in Figure 2, the utility model compression refrigerating system oil eliminator, comprise cylindrical shell 3, cylindrical shell 3 is provided with gases at high pressure import 1 and gases at high pressure outlet 2, oil return pipe 13, ball-cock assembly 8, have additional one first oil return valve 9 on the cylindrical shell 3, liquid level sensor or liquid-level switch, the output signal of liquid level sensor or liquid-level switch is controlled opening and closing of oil return valve.The inlet of described first oil return valve 9 links to each other with oil storage zone, cylindrical shell bottom, and outlet links to each other with oil return pipe 13.Structure chart is seen Fig. 2, and circuit diagram is seen Fig. 7.According to the rise rule of pasta in the cylindrical shell, promptly how long compressor operating needs oil extraction once, and the unlatching of timing controlled first magnetic valve imports the compression crankshaft case with oil.Discontinuous operation time of device KT3 accumulative total compressor for a long time, when arriving setting-up time oil extraction once, the oil extraction time is by time relay KT2 control, and adjustable.The oil extraction time arrives, and resets for a long time that device enters next circulation oil extraction program, and with the oil level in the control oil eliminator, E is the compressor operating contact.
The utility model can also have other embodiment, replaces magnetic valve as available motor-driven valve, and the technical scheme that the mode of equal replacement of all employings or equivalent transformation forms all drops in the protection domain of the present utility model.
