Description
Technical field:
The present invention relates to art of refrigeration units, be specifically related to a kind of refrigeration system and get device express developed.
Background technology:
In art of refrigeration units, except the cryogenic refrigeration equipment of commercial and civilian purposes, also have a lot of refrigeration systems be for industrial needs matching used.For example the vacuum field just needs supporting use deep freeze refrigeration plant Polycold (below subzero 100 degree); In these equipment; The compressor oil that refrigeration valve or capillary can be entered into low-temperature space with cold-producing medium stops up, thereby influences refrigeration, seriously influences production efficiency.Up to the present, equipment producer also neither one completely solution solve this problem.At present, in refrigeration plant,, treat that temperature in the insulation of equipment material rises to after the room temperature refrigeration valve of opening of short time and alleviates in case when this problem occurring, can only be through shutting down.Because what the low temperature of equipment partly adopted is that polyurethane foam insulation material heat insulation effect is very good, so so usually intensification needs one to two day, the middle high-temperature region that the back of heating up leans on gravity compressor oil to be fallen back to equipment.And the remission effect of doing does not so ensure yet.Therefore, after equipment breaks down, shut down two days later and just might recover, but final effect does not ensure.This technical problem is unacceptable for the enterprise of serialization large-scale production.
Summary of the invention:
The purpose of this invention is to provide refrigeration system and get device express developed; It is applicable to dissimilar and refrigeration plant model; Can be widely used in the refrigeration system of various models; Satisfy its quick oil of alleviating and block up phenomenon and the inner needs that heat up that keep in repair of refrigeration plant heat-insulation layer, reduce in large-scale production process and block up the downtime of causing, thereby effectively enhance productivity because of refrigeration system oil.
In order to solve the existing problem of background technology; The present invention adopts following technical scheme: it comprises diffusion chamber, oilless (oil free) compressor, coil pipe, coil pipe protection switch, high pressure gauge, magnetic valve, system maintenance mouth, compressor low-pressure end, vavuum pump; Diffusion chamber is connected with oilless (oil free) compressor; Oilless (oil free) compressor is connected with an end of coil pipe, and the other end of coil pipe is connected with an end of magnetic valve, and the other end of magnetic valve is connected with the system maintenance mouth; The coil pipe protection switch is connected between oilless (oil free) compressor and the coil pipe; High pressure gauge is connected between coil pipe protection switch and the oilless (oil free) compressor, and the compressor low-pressure end is connected between oilless (oil free) compressor and the coil pipe, and vavuum pump is connected between oilless (oil free) compressor and the compressor low-pressure end.
Be provided with low-pressure meter between described diffusion chamber and the oilless (oil free) compressor.
The below of described coil pipe is provided with constant temperature heating device.
Be provided with pressure switch between described coil pipe and the magnetic valve.
The present invention has following beneficial effect: be applicable to dissimilar and refrigeration plant model; Can be widely used in the refrigeration system of various models; Satisfy its oily needs that block up phenomenon and the inner maintenance intensification of refrigeration plant heat-insulation layer of alleviation fast; Minimizing is blocked up the downtime of causing because refrigeration system is oily in large-scale production process, thereby effectively enhances productivity.
Description of drawings:
Fig. 1 is a structural representation of the present invention.
The specific embodiment:
Referring to Fig. 1; This specific embodiment adopts following technical scheme: it comprises diffusion chamber 1, oilless (oil free) compressor 3, coil pipe 4, coil pipe protection switch 5, high pressure gauge 6, magnetic valve 8, system maintenance mouth 9, compressor low-pressure end 11, vavuum pump 12; Diffusion chamber 1 is connected with oilless (oil free) compressor 3; Oilless (oil free) compressor 3 is connected with an end of coil pipe 4, and the other end of coil pipe 4 is connected with an end of magnetic valve 8, and the other end of magnetic valve 8 is connected with system maintenance mouth 9; Coil pipe protection switch 5 is connected between oilless (oil free) compressor 3 and the coil pipe 4; High pressure gauge 6 is connected between coil pipe protection switch 5 and the oilless (oil free) compressor 3, and compressor low-pressure end 11 is connected between oilless (oil free) compressor 3 and the coil pipe 4, and vavuum pump 12 is connected between oilless (oil free) compressor 3 and the compressor low-pressure end 11.
Be provided with low-pressure meter 2 between described diffusion chamber 1 and the oilless (oil free) compressor 3.
The below of described coil pipe 4 is provided with constant temperature heating device 7.
Be provided with pressure switch 10 between described coil pipe 4 and the magnetic valve 8.
This specific embodiment is utilized the cold-producing medium of the middle high-temperature region of refrigeration plant, breaks through cold direction by a compressor and circulates, and through increased pressure, heated at constant temperature is strengthened the effect of recycled back simultaneously.In the recycled back process; Because the cold-producing medium in the general refrigeration plant and the selection of compressor oil; It all is " optimum " collocation of making according to the chemical characteristic of cold-producing medium and compressor oil by the manufacturer of refrigeration plant; Compressor oil wherein all has the characteristic that viscosity can reduce under the situation of middle high temperature.Therefore the middle high-temperature region cold-producing medium of circulation can heat up the compressor oil that is blocked in capillary or magnetic valve in the other direction; Its viscosity is reduced; Rise to when being higher than the compressor oil freezing point temperature in the temperature of block part; The obstruction material viscosity at " oil is stifled " position reduces, and finally brings back to middle high-temperature region through cold-producing medium.Thereby in very short time (actual test data is about 5 minutes), significantly eliminate " oil is stifled " phenomenon, resume production.
This specific embodiment is applicable to dissimilar and refrigeration plant model; Can be widely used in the refrigeration system of various models; Satisfy its oily needs that block up phenomenon and the inner maintenance intensification of refrigeration plant heat-insulation layer of alleviation fast; Minimizing is blocked up the downtime of causing because refrigeration system is oily in large-scale production process, thereby effectively enhances productivity.
