Abstract
A refrigerator with a lubricating oil recharging device comprises a refrigerator body and an ice machine gas phase inlet. The refrigerator is technically characterized in that the ice machine gas phase inlet is connected with an ice machine oil return tank through a pipeline, and an inlet of the ice machine oil return tank sequentially passes through an oil pipe with a valve, a reducing socket, a rubber tube, a check valve, an oil pump and a suction pipe to be connected with an oil storage tank. The ice machine oil return tank can be filled with lubricating oil without halting an ice machine, the problems that in the prior art, the ice machine halts due to oil shortage, and refrigerant needs to be discharged for pressure relief and oil recharging are solved, and it is avoided that the ice machine halts for oil recharging due to shortage of lubricating oil. The refrigerator is ingenious in structural design, outstanding in effect, low in production and maintenance cost and convenient to operate. Halt production accidents of the ice machine are avoided. Operation is convenient, lubricating oil can be recharged at any time, and long-term operation of the refrigerator is guaranteed.
Description
Technical field
The utility model relates to technical field of chemical, the refrigeration machine with lubricating oil recharging oil device specifically using in PE device cooling system.
Background technology
Traditional PE(polyethylene) device is in actual production, and refrigeration machine (ice maker) cold-producing medium (propylene) machine oil mixes, and compressor is discharged propylene both vapor compression rear exhaust port.Lubricating oil in cold-producing medium is separated in oil eliminator, gets back to compressor through oil cooler to suitable temperature.But due to ice maker long-term operation, lubricating oil gasification is lost to oil liquid level and rolls off the production line, the chain autostop of reporting to the police (can not start).Necessary release refrigerant emission propylene, adds lubricating oil, and system vacuumizes, and again fills cold-producing medium propylene.Cause production accident, cause discharge device of air system shutdown.Cause economic loss.For this reason, need badly and existing ice maker is added to lubricating oil improve.
Summary of the invention
The purpose of this utility model is to provide a kind of refrigeration machine with lubricating oil recharging oil device.
The purpose of this utility model is achieved in that it includes refrigeration machine, ice machine gas phase entrance, it is characterized in that: ice machine gas phase entrance is connected with ice machine oil return tank by pipeline, its import of described ice machine oil return tank is successively by the oil pipe with valve, reducing pipe collar, sebific duct, check (non-return) valve, oil pump, suction line and oil storage tank are connected.
The utility model comprises: described sebific duct is high-pressure rubber pipe.
The utility model also comprises: described oil pump is high pressure hand-operated oil pump.
The advantage the utlity model has and positive technique effect are: ice maker does not need to shut down just adds lubricating oil in the tank of ice maker oil return in the past, has solved ice maker oil starvation in prior art and has stopped, refrigerant emission, the problem of release repairing; And avoid causing shutting down repairing because ice maker lacks lubricating oil.Its structural design is ingenious, remarkably productive, and production maintenance cost is low, easy to operate.Avoid ice maker to shut down production accident.Handled easily, can add lubricating oil at any time, the normal periodic duty of guarantee equipment.
The utility model also has simple and reasonable, and improvement cost is low, and method is simple to operation, safe and reliable, the advantages such as long service life.
Brief description of the drawings
Accompanying drawing 1 is structural representation of the present utility model.
In figure, sequence number illustrates: 1 is that ice machine, 2 is that ice machine gas phase entrance, 3 is that pipeline, 4 is that ice machine oil return tank, 5 is that valve, 6 is that oil pipe, 7 is that reducing pipe collar, 8 is that high-pressure rubber pipe, 9 is that check (non-return) valve, 10 is that high pressure hand-operated oil pump, 11 is that suction line, 12 is oil storage tank.
Below in conjunction with accompanying drawing and by example, the utility model is described in further detail; but following example is only the utility model example wherein; do not represent the rights protection scope that the utility model limits, rights protection scope of the present utility model is as the criterion with claim.
Detailed description of the invention
Below in conjunction with accompanying drawing 1, the utility model is described below.
As shown in Figure 1, in figure 1 is that ice machine, 2 is ice machine gas phase entrance, ice machine gas phase entrance 2 is connected with ice machine oil return tank 4 by pipeline 3, described ice machine oil return tank 4 its imports are successively by the oil pipe 6 with valve 5, reducing pipe collar 7, high-pressure rubber pipe 8, check (non-return) valve 9, high pressure hand-operated oil pump 10, suction line 11 and oil storage tank 12 are connected.
Specific works process of the present utility model is: in the time that ice machine need to be added lubricating oil, first Open valve 5, by starting lubricating oil that high pressure hand-operated oil pump 10 adds needs from oil storage tank 12, get in oil return tank 4 through suction line 11, check (non-return) valve 9, high-pressure rubber pipe 8, reducing pipe collar 7 and oil pipe 6 successively, be pressed onto ice maker gas phase entrance 2 by oil return tank 4 and pipeline 3 again, thereby add to the oil separating tank in ice machine 1.Method is simple to operation, safe and reliable.
