Description
Technical field
It is particularly a kind of for connecting rotor compressor and liquid storage cylinder the present invention relates to a kind of rotor compressor technical field
Connection method and connector.
Background technology
Rotor-type compressor is mainly made up of closed barrel with liquid storage cylinder, and closed barrel constitutes ground built with parts such as cylinders
Compressor pump component etc., connecting connection parts substantially have following four type under existing rotor-type compressor.
First type of the prior art, cylinder connecting tube welds together with closed barrel.Cylinder intubation is step
Shape pipe, cylinder intubation small end is inwardly inserted into cylinder suction hole by cylinder connecting tube.Cylinder intubation is that copper pipe is made easily change
Shape, to make cylinder intubation and cylinder suction hole coordinate tight, interference is risen into a steel pipe socket in cylinder intubation small end.Its is main
Purpose is that the characteristics of being unlikely to deform using steel pipe ensures air tight between cylinder intubation and cylinder suction hole.Liquid storage cylinder outlet bend pipe
In the big end of insertion cylinder intubation, both gaps coordinate.Its middle cylinder body connecting tube, cylinder intubation, liquid storage cylinder outlet bend pipe are copper
Pipe is made, and the effective soldering of the above three welds together along mating part inside and outside circle.This lower connecting connection parts are primarily present shortcoming
It is：Need separately to do a steel pipe socket in the process installed, and need one and rise into the operation of steel pipe socket, while with compression
The Continuous optimization of machine cost needs, and steel pipe substitutes the development trend of copper pipe and automatic welding, and compare reservoir escaping pipe
Duan Caiyong copper pipe costs are still higher, not as steel pipe economy.
Second type of the prior art, cylinder connecting tube welds together with closed barrel.Cylinder intubation is step
Shape integral tube, cylinder intubation small end is inserted in cylinder suction hole by cylinder connecting tube, liquid storage cylinder escaping pipe insertion cylinder intubation
In big end.Wherein cylinder intubation is connected ligament cooperation with cylinder, and cylinder intubation coordinates with liquid storage cylinder outlet bend pipe gap.Cylinder
Connecting tube and liquid storage cylinder outlet bend pipe are made up of copper pipe, and cylinder intubation must be made of steel pipe, tight with cylinder intake hole to ensure
Close fit, to ensure welding quality, and in the part copper facing not coordinated with cylinder suction hole, the effective soldering of the above three is along auxiliary section
The inside and outside circle for dividing welds together.This lower connecting connection parts its be primarily present and have the disadvantage：It is lasting excellent with compressor cost
Changing needs, and steel pipe substitutes the development trend of copper pipe and automatic welding, the reservoir outlet bend loss that compares using copper pipe into
This is still higher, not as steel pipe economy.
The third type of the prior art, cylinder connecting tube welds together with closed barrel, and cylinder intubation small end leads to
Cross in cylinder connecting tube insertion cylinder suction hole, in the big end of liquid storage cylinder outlet bend pipe insertion cylinder intubation.Liquid storage cylinder outlet bend pipe
Coordinate with cylinder intubation gap.Cylinder connecting tube is copper pipe with liquid storage cylinder escaping pipe, and above-mentioned three effective soldering is along mating part
Inside and outside circle welds together.Cylinder intubation small end is steel pipe, and big end is copper pipe, and whole cylinder intubation is matched somebody with somebody by steel pipe with copper pipe gap
Merge along coordinating circumference to be welded into, cylinder intubation copper tube sections coordinate with cylinder connecting tube, liquid storage cylinder outlet bend pipe gap.Under this
It is primarily present that shortcoming is relatively costly to connecting connection parts, as the Continuous optimization of compressor cost needs, steel pipe substitute copper pipe with
And the development trend of automatic welding, the reservoir outlet bend pipe that compares uses copper pipe cost still higher, not as steel pipe economy.
4th type of the prior art, cylinder connecting tube welds together with closed barrel, and cylinder intubation small end is not
Family name's taper tube, is inserted in cylinder Morse's taper suction hole by cylinder connecting tube, and liquid storage cylinder outlet bend pipe insertion cylinder intubation is big
In end, liquid storage cylinder outlet bend pipe coordinates with cylinder intubation gap.Cylinder intubation, cylinder connecting tube and liquid storage cylinder outlet bend pipe are
Copper pipe, above-mentioned three effective soldering welds together along mating part inside and outside circle.This lower connecting connection parts its be primarily present shortcoming
Relatively costly, cylinder Morse's taper suction hole, cylinder intubation small end Morse's taper tube portion difficulty of processing are larger, copper pipe cost compared with
Height, as the Continuous optimization of compressor cost needs, steel pipe substitutes the development trend of copper pipe and automatic welding, and compare gas
Cylinder intubation uses copper pipe, and reservoir outlet bend pipe is still higher using copper pipe cost, not as steel pipe economy.
Therefore, there is following technical problem in the prior art, it is necessary to rise into steel pipe socket or copper plate, Morse's taper tube portion
Difficulty of processing is larger, copper pipe is relatively costly etc. increased processing cost and operation, as the Continuous optimization of compressor cost needs,
Steel pipe substitutes the development trend of copper pipe and automatic welding, and the cylinder intubation that compares uses copper pipe, reservoir outlet bend pipe to adopt
It is still higher with copper pipe cost, not as steel pipe economy.
Disclosed above- mentioned information is used only for understanding of the enhancing to background of the present invention in the background section, it is thus possible to
Information comprising prior art known to a person of ordinary skill in the art in not constituting home.
