Abstract
The utility model relates to parts of a refrigeration compressor, in particular to a taper hole suction pipe applied to the refrigeration compressor. The taper hole suction pipe is characterized by being integrally formed by butting a straight tube section, a tapered section and a special-shaped section in sequence, wherein the special-shaped section is composed of a sudden expanding section and a straight tube section. The taper hole suction pipe solves the problems that refrigerating steam in a flat-straight type suction pipe of a traditional refrigeration compressor suffers from a large pressure loss throughout the system, and the air suction rate is low. The taper hole suction pipe is an air suction pipe mainly used for the refrigeration compressor.
Description
The (1) technical field: the utility model relates to the component of refrigeration compressor, especially a kind of taper hole sucking pipe that is applied to refrigeration compressor.
The (2) background technique: the refrigeration compressor air suction pipe sucks refrigerant vapour from vaporizer; Through muffler assembly sqouynd absorption lowering noise; Get into compresser cylinder (suction line) through the suction valve chip suction port,, discharge compressor and get into condenser along the gas exhaust piping that exhaust valve plate exhaust port, cylinder head, exhaust coil pipe, outlet pipe are formed again through compressor compresses; Get into vaporizer through throttle element throttling step-down, so constituted the suction and discharge pipeline of whole refrigeration system.Sucking pipe is as the first component of refrigerant vapour entering compressor, and its quality directly affects the overall performance of compressor.Design good sucking pipe, can reduce the pressure loss of whole compressor suction system, improve the gettering efficiency of refrigeration compressor, thereby further improve the COP of refrigeration compressor.
Traditional sucking pipe structure is as shown in Figure 1; It is docked successively by reaming section, direct tube section and sudden change extension diameter section three parts and is integrally formed; The sucking pipe of this structure; Because sucking pipe is flat type, the sucking pipe pipeline flow is little, flows into refrigerant vapor bigger along the stroke pressure loss of flat type sucking pipe.Therefore, a kind of sucking pipe that can address the above problem well of design is very to be necessary.
The (3) summary of the invention: the purpose of the utility model is exactly refrigerant vapor in the flat type sucking pipe that will solve on traditional refrigeration compressor problems such as big and gettering efficiency is low along stroke pressure loss, and a kind of taper hole sucking pipe that is applied to refrigeration compressor is provided.
The concrete scheme of the utility model is: a kind of taper hole sucking pipe that is applied to refrigeration compressor is characterized in that: it is docked successively by direct tube section, conical section and abnormity section three parts and is integrally formed, and wherein, the abnormity section is made up of sudden change extension diameter section and direct tube section.
The wall thickness t of direct tube section described in the utility model, conical section and abnormity section three parts is 0.5mm～2mm.
The cone angle of conical section described in the utility model is 4 °～20 °.
The entry end of conical section described in the utility model D outer diameter is 4mm～12mm.
In the utility model owing to be designed with conical section; The flow of refrigerant vapor that make to flow into the utility model is obviously greater than the flow of common straight cylinder type sucking pipe; The loss of total pressure of the utility model suction refrigerant vapor is less like this, and gettering efficiency is higher, has improved the COP of refrigeration compressor greatly.
The (4) description of drawings:
Fig. 1 is the main sectional view of the sucking pipe of traditional refrigeration compressor;
Fig. 2 is the main sectional view of the utility model.
Among the figure: 1-direct tube section, 2-conical section, the 3-extension diameter section that suddenlys change, 4-direct tube section.
The (5) embodiment:
Referring to Fig. 2; The utility model is docked successively and is integrally formed by direct tube section 1, conical section 2 and abnormity section (the abnormity section is made up of with direct tube section 4 sudden change extension diameter section 3) three parts; The wall thickness t of direct tube section 1, conical section 2 and abnormity section three parts is 0.5mm～2mm; The cone angle of conical section 2 is 4 °～20 °, and conical section 2 entry end D outer diameter are 4mm～12mm.During concrete the use, the direct tube section 1 of the utility model is connected with the pipeline of refrigerator refrigeration system, abnormity section is connected with lower casing.
Claims (4)
1. taper hole sucking pipe that is applied to refrigeration compressor is characterized in that: it is docked successively by direct tube section, conical section and abnormity section three parts and is integrally formed, and wherein, the abnormity section is made up of sudden change extension diameter section and direct tube section.
2. a kind of taper hole sucking pipe that is applied to refrigeration compressor according to claim 1 is characterized in that: the wall thickness t of said direct tube section, conical section and abnormity section three parts is 0.5mm～2mm.
