Description
Technical field
This utility model relates to a kind of oil free screw compressor.
Background technology
Helical impeller compressor is mainly to be made up of three parts: cylindrical cylinder, with spiral
The rotary-piston of groove and variable-pitch auger blade.The external diameter of rotary-piston less than cylinder bore diameter, it
Eccentrically mounted with cylinder 1, its offset should ensure that outer surface of piston and cylinder inner wall face are in bottom
Tangent, the outrigger shaft at piston two ends be bearing on bearing and around its center line rotate, then with
Crescent-shaped space is formed between cylinder.The external diameter etc. of the variable-pitch auger blade being made up of elastomeric material
In cylinder bore diameter, the Changing Pattern of blade pitch and the Changing Pattern one of helicla flute pitch on piston
Causing, after it loads in helicla flute, its periphery contacts with cylinder inner wall face, therefore by crescent moon
Several spiral type crescent moon spaces closed are encroached on in shape space, here it is helical-blade compressor
Working chamber, also known as element volume.
Compressor is regarded as the heart of refrigeration system, can show the special name of compressor characteristics
Word is referred to as vapor pump.The responsibility that compressor reality is undertaken is an up pressure, by pressure of inspiration(Pi) shape
State brings up to discharge pressure state.Compression ratio is a kind of technology representation of pressure differential, and it contains
Justice is the high-pressure side absolute pressure absolute pressure divided by low-pressure side.The calculating of compression ratio must use
Absolute pressure value.In order to avoid making compression ratio value of calculation that negative value to occur, calculate during pressure ratio necessary
Use absolute pressure rather than meter pressure.Use absolute pressure value just can make compression ratio value of calculation
For on the occasion of, the most meaningful.The compressor used in refrigeration and air conditioner industry has 5 big types:
Reciprocating, screw, swinging, vortex and centrifugal, the most reciprocating be small-sized and in
Type business-use refrigrating system is applied most a kind of compressors.Screw compressor is mainly used in greatly
Type commercialization and industrial system.
Current existing compressor arrangement is complicated, and volume is relatively big, and compression effectiveness is general, and noise is relatively
Greatly.
Utility model content
The technical problems to be solved in the utility model is to provide a kind of compact conformation, and volume is little, pressure
Contracting effective, operation stability is high, the oil free screw compressor that noise is little.
For solving the problems referred to above, this utility model adopts the following technical scheme that
A kind of oil free screw compressor, including casing, rotary-piston, main shaft and helical blade,
Being provided with cylinder in described casing, described rotary-piston is located in cylinder, and described main shaft is arranged on
In the middle part of rotary-piston, described helical blade is arranged on outside rotary-piston, depends on outside described cylinder
Secondary rotor and the motor stator of being provided with, described rotor is connected with spindle drive, described
Motor stator is fixing with casing to be connected, and described casing is respectively arranged with air inlet pipe and exhaustor,
Described cylinder two ends are provided with bearing block, and described bearing block is fixing with casing to be connected, described rotation
Piston is rotationally connected with bearing block.
As preferably, described cylinder two ends are respectively arranged with air intake duct and exhaust duct, keep air
Circulate smooth and easy.
As preferably, described air intake duct connects with air inlet pipe, maintains the circulation of air smooth and easy.
As preferably, described exhaust duct connects with exhaustor, maintains the circulation of air smooth and easy.
As preferably, described air inlet pipe and exhaustor are fixing with casing respectively to be connected, and keeps structure
Reliable and stable.
As preferably, the described rounded setting of casing surrounding.
As preferably, in described casing, it is also equipped with radiating tube, keeps good heat dissipation effect.
The beneficial effects of the utility model are: rotor and the motor stator of setting are located at casing
In, keeping compact conformation, volume is little；The helical blade arranged is arranged on outside rotary-piston and protects
Holding compression effectiveness good, noise is little；It is high that the bearing block arranged remains on stability；Arrange dissipates
Heat pipe keeps good heat dissipation effect.
