Description
Technical field
The present invention relates to Compressor Technology field, more particularly to a kind of compressor exhaust pipe and with this blast pipe
Compressor.
Background technology
The design feature of rotary compressor, which is determined, can carry a part of lubricating oil in discharged high-pressure refrigerant, such as
The lubricating oil too high levels that fruit carries, can not only reduce the reliability of compressor, and can influence the performance of air-conditioning system, institute
So that the oil extraction rate of rotary compressor is the important technology index of compressor.In addition, R290 as a kind of environment friendly refrigerating fluid into
To compare potential Substitute Working Medium, but dissolubility is preferable in conventional compressor lubricant oil due to it, so in order to ensure
The performance of compressor must reduce injection flow.Significantly more efficient oil separating structure is needed inside rotary compressor.
The content of the invention
For above-mentioned problem, technical purpose of the invention is to provide a kind of compressor exhaust pipe, of the invention
Another object is a kind of compressor with this compressor exhaust pipe of offer.
The present invention is achieved through the following technical solutions：
The compressor exhaust pipe of the present invention, including：Blast pipe and the diversion component being installed in blast pipe, the diversion division
Part includes some first spiral stream guidance portions and the second spiral stream guidance portion, and the first spiral stream guidance portion and the second spiral stream guidance portion are mutual
Separately install, the first spiral stream guidance portion is oppositely oriented with the second spiral stream guidance portion.
The axial length in the compressor exhaust pipe of the present invention, the first spiral stream guidance portion and the second spiral stream guidance portion is half
The integral multiple of individual pitch.
The axial length in the compressor exhaust pipe of the present invention, the first spiral stream guidance portion and the second spiral stream guidance portion is half
Individual pitch.
The compressor exhaust pipe of the present invention, the exhaust bottom of the tube is provided with uniform outage, and the outage is located at and led
The lower section of stream unit.
A kind of compressor, with above-mentioned compressor blast pipe, the also motor including cylinder and in cylinder, the cylinder
Top be provided with upper outer cover, the blast pipe through upper outer cover will inside and outside compressor connect, the blast pipe is by being welded and fixed
In on upper outer cover.
The beneficial effects of the invention are as follows:
By being provided with the diversion component assembled by left-hand screw diversion division and right-hand screw diversion division in blast pipe,
Helical flow path of the fluid by diversion component formation inflection so that fluid formation two-way, in flow process, density is larger
Oil droplet collided in diversion component and blast pipe wall due to the effect of inertia, so that oil droplet be separated from refrigerant gas,
And discharged oil droplet by the outage on blast pipe, and the effect in flow process by helical blade so that in air-flow
Oil droplet due to density it is larger, under the influence of centrifugal force, with larger radial velocity so that oil droplet radially flows
Dynamic, oil droplet is attached to exhaust inside pipe wall, so that oil droplet be separated, and this blast pipe and compressor with this blast pipe can
The efficiency for excluding oil droplet is greatly improved, multiple impacts effect improves the effect of Oil-gas Separation, greatly reduces the oil extraction of compressor
Rate；The compact conformation of blast pipe, small volume does not influence the topology layout of compressor.

Embodiment
The present invention is described in detail below in conjunction with the accompanying drawings.
Compressor exhaust pipe as shown in Figure 1, including：Blast pipe 1 and the diversion component 2 being installed in blast pipe 1, such as scheme
2~4, the diversion component 2 includes spiral stream guidance portion 202 of some first spiral stream guidance portions 201 and second, and first spiral is led
Spiral stream guidance portion 202 of stream portion 201 and second is apart from one another by installation, the rotation direction phase in the first spiral stream guidance portion and the second spiral stream guidance portion
Instead.
The axial length in spiral stream guidance portion 202 of the first spiral stream guidance portion 201 and second is the integral multiple of half pitch,
Best, the axial length in spiral stream guidance portion 202 of the first spiral stream guidance portion 201 and second is half pitch, to be formed more
Many water conservancy diversion inflection areas, so as to improve the efficiency of separation oil.Blast pipe at diversion component 2 is installed to be horizontally disposed with, the bottom of blast pipe 1
Portion is provided with uniform outage 3, and the outage 3 is located at the lower section of diversion component 2.As shown in figure 5, air-flow enters blast pipe
After in 1, in the presence of diversion component, streamline 4 and streamline 5 are formed, air-flow is flowed after half cycle respectively along streamline 4 and streamline 5, passed through
The effect of diversion component 2 and blast pipe 1 is crossed, larger oil droplet is hit due to the effect of inertia and is attached to diversion component and row
The wall of tracheae, air-flow flows half cycle along streamline 4 and streamline 5 again, and oil droplet hits and is attached to diversion component and blast pipe again
Wall, circulate successively, the fluid in air-flow separated, while oil droplet is constantly attached on wall, effect of the oil droplet in gravity
It is lower to be flowed down along wall, so as to which the fluid in blast pipe is discharged by outage.
A kind of compressor with above-mentioned compressor blast pipe, including cylinder 8 and the motor 9 in cylinder 8, the cylinder
