Description

The rotary compressor pump of slide bar

Technical field

The utility model relates to a kind of compressor pump, especially with the move up and down rotary compressor pump of slide bar of eccentric rotor body rotation pressurized gas, liquid of slide bar.

Background technique

Each industrial enterprise unit or the employed compressor pump of family (for example freezer, refrigerator, air conditioner, aeration pump) adopt the back and forth reciprocating type compressor pump of operation of piston mostly at present, or adopt the rotary compressor pump of eccentric rotor operation; Though that they all are current performances is more superior, use more general compressor pump, they all have its not enough one side, are exactly that volume is bigger than normal; Complex structure; Friction factor is high, and compressing force is powerful inadequately, and electrisity consumption is big.

Summary of the invention

The purpose of the utility model is to provide a kind of volume less, simple in structure, and friction factor is little, and compressing force is more powerful, the rotary compressor pump of the slide bar that is widely used in various high pressure pump systems that power consumption is less.

The utility model is realized through following mode; Be built-in with an eccentric rotor body (4) at a following square circular cylinder body (3) that is equipped with sliding cylinder (1), slide bar (2); Eccentric rotor body (4) is made up of external core of eccentric rotor (5) and eccentric rotor body inner core (6); The inner edge of the external core of eccentric rotor is inserted bearing or copper sheathing (7), and eccentric rotor body inner core (6) will be packed in its bearing or the copper sheathing (7) flexibly rotationally, has a slide bar axis hole (8) that is inserted in slide bar (2) lower end on the eccentric rotor body (4) of the external core of eccentric rotor (5); And slide bar (2) lower end to the property moved be packed into wherein hermetically; The external core of eccentric rotor (5) is packed into and is had suction port (9) on the side cylinder body of slide bar lower end, has relief opening (10) on the opposite side cylinder body, and eccentric rotor body inner core (6) is equipped with an eccentric shaft away from its central point (11); On all the other eccentric rotor body inner cores of eccentric rotor body inner core eccentric shaft (11), have depolarized hole (12); Eccentric shaft (11) on the eccentric rotor body inner core is enclosed in the central shaft hole (13) at center in the cylinder body, and making has any to be in operation on the external core of eccentric rotor (5) outer rim can be close to the cylinder block inwall all the time, like Fig. 1.

The remarkable advantage of the utility model is that its purposes is wider, not only can make the refrigerant compression pump, but also can be used for the high flow capacity gas compression.

Another advantage of the utility model is that it is simple in structure, and friction factor is little, and volume is little, and is easy to manufacture, is convenient to popularize.

Embodiment

An existing specific embodiment with reference to description of drawings the utility model; In a following square circular cylinder body (3) that is equipped with sliding cylinder (1), slide bar (2); Be equipped with an eccentric rotor body (4); Eccentric rotor body (4) is made up of external core of eccentric rotor (5) and eccentric rotor body inner core (6), and the inner edge of the external core of eccentric rotor is inserted bearing or copper sheathing (7), and will be enclosed in eccentric rotor body inner core (6) in its bearing or the copper sheathing (7) flexibly rotationally; Have a slide bar axis hole (8) that is inserted in slide bar (2) lower end on the eccentric rotor body (4) of the external core of eccentric rotor (5); And slide bar (2) lower end will the property moved be packed into wherein hermetically, the external core of eccentric rotor (5) outer rim is packed into and is had suction port (9) on the side cylinder body (3) of slide bar lower end, has relief opening (10) on the opposite side cylinder body; Eccentric rotor body inner core (6) is equipped with an eccentric shaft away from its central point (11); On all the other eccentric rotor body inner cores of eccentric rotor body inner core eccentric shaft (11), have depolarized hole (12), the eccentric shaft (11) on the eccentric rotor body inner core will be enclosed in the central shaft hole (13) at center in the cylinder body, and making has any to be in operation on the external core of eccentric rotor (5) outer rim can be close to the cylinder block inwall all the time; Like Fig. 1, constituted a most preferred embodiment of the utility model.Space in the cylinder block is by the slide bar separated into two parts, and a side sections of slide bar communicates with suction port, as low pressure chamber; The opposite side part of slide bar communicates with relief opening, as hyperbaric chamber, and the external edge of eccentric rotor in gas that comes by suction port or the liquid entering cylinder body and the space of slide bar; When eccentric rotor body inner core rotates, drive bearing or copper sheathing and rotate simultaneously, rotate thereby also drive the external core of eccentric rotor; The moving property of slide bar is moved up and down in cylinder with in the sliding cylinder hermetically; Also make simultaneously the external core outer rim of eccentric rotor can have any to be close to the moving property sealing of inboard wall of cylinder block ground all the time and rotate, the area of low pressure chamber is increasing, and the gas or the liquid of inspiration constantly increase; And hyperbaric chamber is compressed gradually and diminishes; Discharge gas or liquid through relief opening at last, and the area of low pressure chamber enlarges constantly, constantly suck new gas or liquid again; And the external core outer rim of eccentric rotor is through pushing, compress, discharge relief opening with gas or liquid to the relief opening direction through suction port behind the relief opening, so through circulating.
