Abstract
The invention belongs to the field of general machinery, and relates to an intelligent automatic control screw refrigerating compressor, which is improvement in the structural design of a compressor. The intelligent automatic control screw refrigerating compressor is characterized in that: a screw compressor is connected with a motor by a shaft coupling; an intake valve and an air intake filter are arranged at an intake port of the screw compressor; an exhaust valve is arranged at an exhaust opening of the screw compressor; a safety valve is arranged on the screw compressor; an oil filter and an oil separator are arranged between an oil pump and a water/oil cooler; and an oil pressure adjustment valve is arranged between an inlet and an outlet of the oil pump. The intelligent automatic control screw refrigerating compressor of the invention is designed for shortcomings and problems in the prior art, and solves the problems of oil pump overload, main frame overload, low oil pressure difference, high exhaust pressure, high oil temperature, great intake pressure difference and the like so as to ensure the good running state of the compressor unit.
Description
Technical field
The invention belongs to the universal machine field, is to the improvement of compressor arrangement design, relates to a kind of intelligent automatic control screw refrigerating compressor.
Background technology
At present, the compressor of domestic production, its structure is that toggle adopts sealed bearing to realize, be that connecting rod is connected employing both-end sealed bearing with bent axle, connecting rod is connected the employing needle bearing with piston, add the sealing form, this structure has been used many decades at home and abroad, is still using at present.Along with environmental protection requirement compressor of the prior art can't satisfy the demands.Have that bearing is fragile, service life is low; Problems such as dismounting inconvenience, maintenance difficult bring great loss for user and production.
Summary of the invention
The present invention has overcome the defective of above-mentioned existence, and purpose is to be problem such as solve oil pump overload, main frame overload, the oil pressure difference is low, row pressure is high, oily temperature height and air-breathing pressure reduction are big, and a kind of intelligent automatic control screw refrigerating compressor is provided.
Intelligent automatic control screw refrigerating compressor content Description of the present invention:
Intelligent automatic control screw refrigerating compressor of the present invention, by: console, safety valve, water-cooled/oil cooler, air bleeding valve, oil strainer, motor, shaft coupling, intake valve, air-breathing filter, connecting rod compressor, oil pump, oil eliminator and oil pressure adjusting valve are formed, it is characterized in that: be connected by shaft coupling between helical-lobe compressor and the motor, at the air entry place of helical-lobe compressor intake valve and air-breathing filter are set, air bleeding valve are set in the exhaust ports of helical-lobe compressor.
Safety valve is set on helical-lobe compressor.
Oil strainer and oil eliminator are set between oil pump and the water-cooled/oil cooler.
Between the import and export of oil pump, oil pressure adjusting valve is set.
Intelligent automatic control screw refrigerating compressor of the present invention; problem at the deficiencies in the prior art and existence designs; problem such as solved oil pump overload, main frame overload, the oil pressure difference is low, row pressure is high, oily temperature height and air-breathing pressure reduction are big; played control and defencive function, thereby the running status that guarantees compressor bank is good.

Fig. 2 is the intelligent automatic control screw refrigerating compressor side view
Among the figure: the 1st, console, the 2nd, safety valve, the 3rd, water-cooled/oil cooler, the 4th, row's device valve, the 5th, oil strainer, the 6th, motor, the 7th, shaft coupling, the 8th, intake valve, the 9th, air-breathing filter, the 10th, helical-lobe compressor, the 11st, oil pump, the 12nd, oil separation, the 13rd, oil pressure adjusting valve.
The specific embodiment
Intelligent automatic control screw refrigerating compressor of the present invention is achieved in that below in conjunction with accompanying drawing and specifies.See Fig. 1, Fig. 2, intelligent automatic control screw refrigerating compressor by: console 1, safety valve 2, water-cooled/oil cooler 3, air bleeding valve 4, oil strainer 5, motor 6, shaft coupling 7, intake valve 8, air-breathing filter 9, connecting rod compressor 10, oil pump 11, oil eliminator 12 and oil pressure adjusting valve 13 are formed, be connected by shaft coupling 7 between helical-lobe compressor 10 and the motor 6, at the air entry place of helical-lobe compressor 10 intake valve 8 and air-breathing filter 9 are set, air bleeding valve 4 are set in the exhaust ports of helical-lobe compressor 10.
Safety valve 2 is set on helical-lobe compressor 10.
Oil pressure adjusting valve 13 is set between the import and export of oil pump 11.
After the cooling machine oil cooling in water-cooled/oil cooler 3, enter unit, form circulation through oil strainer 5.More than connect by pipe flange, pipe joint valve etc. between each parts.
The electric control part of intelligent automatic control screw refrigerating compressor is divided into electrical control cubicles 1, its operating process is for connecting power supply, send various instructions by 1 pair of intelligent automatic control screw refrigerating compressor of switch board, at first directly start oil pump 11, actuating motor 6 then, motor 6 at first starts for the Y type, after controlling in good time by the time relay, motor 6 becomes the operation of △ type, after operation is normal, carry out operate as normal, energy adjustment is uploaded, is unloaded electromagnetic valve switch by control and realizes.
Temperature controller, pressure differential pressure controller and indicator lamp are housed on the console 1, and switch board is equipped with automatic control, electrical component and the command display to each control and protection position.These components and parts are formed complete display control program together, finish the control to intelligent automatic control screw refrigerating compressor jointly.Simultaneously, 1 pair of oil pump of switch board 11 overload, main frame overload, the oil pressure difference is low, row pressure is high, oily temperature height, air-breathing pressure reduction mostly play control and defencive function, thereby the running status that guarantees compressor is good.
