[0031] Reference is made below to Figures 1 - 7 describe a reciprocating compressor 100 according to an embodiment of the present utility model.
[0032] Referring to Figure 1 and Figure 2 As shown in FIGS. and, a reciprocating compressor 100 according to an embodiment of the present utility model includes: a housing 1, a pump body 2, a first pipe body 3, and a second pipe body 4. Among them, the housing 1 is provided with an installation cavity 10. The pump body 2 includes a compression component. The compression component is disposed inside the housing 1. The compression component is provided with a compression cavity for compressing gas. The compression cavity is provided with a ventilation hole 220 communicating with the installation cavity 10. The first pipe body 3 is directly communicated with the installation cavity 10. The second pipe body 4 is directly communicated with the compression cavity. Both the first pipe body 3 and the second pipe body 4 are used for ventilation. Among them, the first pipe body 3 can also be used for oil injection.
[0033] Since the first pipe body 3 is directly communicated with the installation cavity 10, lubricating oil can be injected into the installation cavity 10 through the first pipe body 3. It should be noted that the oil injection operation is only a process in the production process of the reciprocating compressor 100. After the oil injection operation is completed, it does not affect the ventilation of the first pipe body 3.
[0034] One of the first pipe body 3 and the second pipe body 4 is configured as an intake pipe, and the other of the first pipe body 3 and the second pipe body 4 is configured as an exhaust pipe. When the reciprocating compressor 100 operates, gas enters the compression cavity through the intake pipe and is discharged from the compression cavity through the exhaust pipe after being compressed in the compression cavity.
[0035] The reciprocating compressor 100 according to an embodiment of the present utility model realizes the intake and exhaust of the compression cavity through the first pipe body 3 and the second pipe body 4, and can also perform an oil injection operation through the first pipe body 3. Only two pipes, namely the first pipe body 3 and the second pipe body 4, need to be provided on the housing 1, and there is no need to provide a process pipe in the related art, which reduces the number of pipes on the housing 1, that is, reduces the components of the reciprocating compressor 100, and also reduces the assembly process of the reciprocating compressor 100, greatly reducing the cost of the reciprocating compressor 100.
[0036] Referring to Figure 1 and Figure 2, in some specific embodiments, the first pipe body 3 is configured as an intake pipe, and the second pipe body 4 is configured as an exhaust pipe. When the reciprocating compressor 100 operates, gas enters the installation cavity 10 through the first pipe body 3, then enters the compression cavity through the ventilation hole 220, and is discharged through the second pipe body 4 after being compressed in the compression cavity. In the embodiment of the present utility model, the ventilation hole 220 is formed as an intake hole communicating with the compression cavity, and the installation cavity 10 is formed as a space for storing low-pressure gas.
[0037] In some other specific embodiments, the first pipe body 3 is configured as an exhaust pipe, and the second pipe body 4 is configured as an intake pipe. When the reciprocating compressor 100 operates, gas directly enters the compression cavity through the second pipe body 4, and after being compressed in the compression cavity, enters the installation cavity 10 through the ventilation hole 220, and is finally discharged through the first pipe body 3. In the embodiment of the present utility model, the ventilation hole 220 is formed as an exhaust hole communicating with the compression cavity, and the installation cavity 10 is formed as a space for storing high-pressure gas.
[0038] That is to say, regardless of whether the installation cavity 10 of the reciprocating compressor 100 is designed to belong to the high-pressure side or the low-pressure side, the oil injection operation can be completed through the first pipe body 3, without the need to provide a process pipe in the related art, achieving the effect of reducing the cost of the reciprocating compressor 100.
[0039] Refer to Figure 1 and Figure 2 , in some embodiments, one end of the first pipe body 3 communicating with the installation cavity 10 is arranged in a dislocation manner with the ventilation hole 220.
[0040] Through the above technical solution, the situation that lubricating oil enters the ventilation hole 220 during the oil injection operation is avoided, thereby reducing the content of lubricating oil in the flow path when the reciprocating compressor 100 operates, and ensuring the refrigerating capacity and working efficiency of the reciprocating compressor 100.
[0041] Refer to Figure 1 and Figure 2 , in some further embodiments, the pump body 2 further includes a silencer 22, the silencer 22 is arranged on the compression component, and the ventilation hole 220 is located in the silencer 22.
[0042] In the embodiment of the present utility model, by providing the silencer 22, the noise generated when gas enters or exits the compression cavity is reduced, and the noise generated when the reciprocating compressor 100 operates is reduced.
[0043] In some specific embodiments, the first pipe body 3 is configured as an intake pipe, the second pipe body 4 is configured as an exhaust pipe, the silencer 22 is arranged on the compression component, the ventilation hole 220 is located in the silencer 22, and the silencer 22 is configured as an intake silencer 22.
[0044] In the embodiment of the present utility model, when the reciprocating compressor 100 operates, gas enters the installation cavity 10 through the first pipe body 3, then enters the compression cavity through the intake muffler 22, and is discharged through the second pipe body 4 after being compressed in the compression cavity.
[0045] Through the muffler 22, the noise when the gas enters the compression cavity from the installation cavity 10 is reduced, and the noise generated during the operation of the reciprocating compressor 100 is decreased.
[0046] Referring to Figure 1 and Figure 2 In some further embodiments, the extending direction of one end of the first pipe body 3 close to the installation cavity 10 is the first direction. On the vertical plane of the first direction, the minimum distance between the opening of the end of the first pipe body 3 communicating with the installation cavity 10 and the ventilation hole 220 is D, where D ≥ 1 mm.
[0047] By the above technical solution, the minimum distance between the opening of the end of the first pipe body 3 communicating with the installation cavity 10 and the ventilation hole 220 is defined, thereby further reducing the situation of lubricating oil entering the ventilation hole 220 and ensuring the refrigerating capacity and working efficiency of the reciprocating compressor 100.
[0048] In some specific embodiments, the extending direction of one end of the first pipe body 3 close to the installation cavity 10 is the first direction. On the vertical plane of the first direction, the minimum distance between the opening of the end of the first pipe body 3 communicating with the installation cavity 10 and the ventilation hole 220 is D, where D = 1 mm. In other embodiments, the minimum distance D between the opening of the end of the first pipe body 3 communicating with the installation cavity 10 and the ventilation hole 220 can also be other dimensions such as 3 mm, 4 mm, 5 mm, 10 mm, etc.
[0049] In some embodiments, a bending portion is provided at one end of the first pipe body 3 far from the housing 1.
[0050] By the bending portion, the orientation of the opening of one end of the first pipe body 3 far from the housing 1 is changed, which facilitates the connection of the first pipe body 3 with other structures and improves the installation convenience of the reciprocating compressor 100.
[0051] In some embodiments, a bending portion is provided at one end of the second pipe body 4 far from the housing 1.
[0052] By the bending portion, the orientation of the opening of one end of the second pipe body 4 far from the housing 1 is changed, which facilitates the connection of the second pipe body 4 with other structures and improves the installation convenience of the reciprocating compressor 100.
[0053] In some specific embodiments, a bent portion is provided at one end of the first pipe body 3 away from the housing 1, and a bent portion is also provided at one end of the second pipe body 4 away from the housing 1, and the bent portions of the first pipe body 3 and the second pipe body 4 face the same direction.
[0054] Through the above technical solution, when the staff installs the reciprocating compressor 100, the connection between the first pipe body 3 and other pipes, and the connection between the second pipe body 4 and other pipes can be completed in one direction, effectively improving the convenience of installing the reciprocating compressor 100.

[0056] In the embodiment of the present utility model, the housing 1 is formed by connecting two parts, namely the first part 11 and the second part 12, which reduces the mold opening cost of the housing 1. And when there is damage in the housing 1, only the first part 11 or the second part 12 with the damaged part needs to be replaced, without replacing the whole housing 1, which reduces the maintenance cost of the housing 1.
[0057] It should be noted that the first part 11 and the second part 12 can be connected by means of flange connection, welding or other methods, as long as an installation cavity 10 is formed between the first part 11 and the second part 12.
