Description
Technical field
The present invention relates to hydrogenation stations technical fields more particularly to a kind of cylinder block of hydrogenation stations high pressure hydrogen compressor to cast
Part.
Background technique
Piston compressor, has a piston to move reciprocatingly in barrel cylinder, controls on cylinder into, row
The valve of gas, when piston is reciprocating, the variation in cylinder volume just period, so as to realizing inspiration, compression and the row of gas
Out.Traditional cylinder part is fully sealed due to that can not accomplish, cylinder chamber (high-pressure side) gas can be (low to inoperative chamber
Press side) it reveals, gas leakage will cause serious harm：Cylinder temperature increases, and cylinder block inoperative chamber (low-pressure side) pressure increases, and causes
On the one hand active force power increase wastes unnecessary energy, another aspect pulling force, which increases, even pulls the components such as crosshead, increases
Add the number of vulnerable part.With large-scale compressor develop needs, research and develop one kind adapt to large-scale compressor operation, it is high-efficient,
The good Novel cylinder casting structure of high reliablity, durability becomes a urgent task.
Summary of the invention
The purpose of the present invention is to solve disadvantages existing in the prior art, and a kind of hydrogenation stations high pressure hydrogen proposed
The cylinder block casting of compressor.
To achieve the goals above, present invention employs following technical solutions：
A kind of cylinder block casting of hydrogenation stations high pressure hydrogen compressor, it is characterised in that：Including shell, driving is equipped in shell
Axis, driving axis connection crankshaft, crankshaft connect crosshead component, and crosshead component connects piston, and cylinder block is equipped in shell,
Working chamber is equipped in cylinder block, be slidably connected piston in working chamber, and inlet chamber and discharge chamber are connected on working chamber, is being worked
Intake valve is arranged in the connectivity part of chamber and inlet chamber, and the air inlet of inlet chamber is set on the housing, in working chamber and discharge chamber
Exhaust valve is arranged in connectivity part, and the exhaust outlet of discharge chamber is set on the housing, and inoperative chamber, non-work is arranged in the bottom of working chamber
Make chamber and is connected to the inlet chamber.
Preferably, it is circular cavity that the working chamber cavity, which is cross section, and working chamber is located at the axis of the cylinder block
Place.
Preferably, the inlet chamber and the discharge chamber are arranged with the axisymmetrical of the cylinder block.
The advantage of the invention is that：A kind of cylinder block casting of hydrogenation stations high pressure hydrogen compressor provided by the present invention,
Traditional two Room, one general formula is changed to two Room, two general formula by the device, allow for leaking into this way cylinder inoperative chamber gas return into
Air cavity retrieves utilization, can extend making for entire compressor to avoid a series of harm caused by cylinder block working chamber gas leakage
Use the service life.
Detailed description of the invention
Fig. 1 is a kind of theory structure signal of the cylinder block casting of hydrogenation stations high pressure hydrogen compressor provided by the present invention
Figure.
Specific embodiment
In order to make the objectives, technical solutions, and advantages of the present invention clearer, with reference to the accompanying drawings and embodiments, right
The present invention is further elaborated.It should be appreciated that the specific embodiments described herein are merely illustrative of the present invention, and
It is not used in the restriction present invention.
As shown in Figure 1, a kind of cylinder block casting of hydrogenation stations high pressure hydrogen compressor provided by the invention, including shell 1,
Drive shaft 2 is equipped in shell 1, drive shaft 2 connects crankshaft 3, crankshaft 3 connects crosshead component 4, the connection work of crosshead component 4
Plug 6.1 is equipped with cylinder block 5 in shell 1, working chamber 6 is equipped in cylinder block 5, be slidably connected the piston in working chamber 6
6.1,6 cavity of working chamber is that cross section is circular cavity, and working chamber 6 is located at the axis of the cylinder block 5.
When piston 6.1 moves reciprocatingly in working chamber 6, the variation of the volume generating period in cylinder block 5, so as to reality
Inspiration, compression and the discharge of existing gas.
Inlet chamber 7 and discharge chamber 8 are connected on working chamber 6, the inlet chamber 7 is with the discharge chamber 8 with the cylinder block 5
Axisymmetrical setting.
Intake valve 7.1 is set in the connectivity part of working chamber 6 and inlet chamber 7, the air inlet of inlet chamber 7 is located at the shell 1
On, in the connectivity part of working chamber 6 and discharge chamber 8, exhaust valve 8.1 is set, the exhaust outlet of discharge chamber 8 is located on the shell 1,
Inoperative chamber 9 is arranged in the bottom of working chamber 6, and inoperative chamber 9 is connected to the inlet chamber 7, according to the theoretical circulation of compressor stage and
What actual cycle calculated inoperative chamber 9 and the inlet chamber 7 opens port size, remaining components is supported by the prior art.
The cylinder block 5 is fully sealed due to that can not accomplish, causes the high pressure gas in cylinder working chamber 6 can be to non-work
Make leakage in chamber 9, at this moment, the gas being leaked in inoperative chamber 9 can come back in inlet chamber 7, reach re-using.
Working principle：Drive shaft 2 drives crosshead component 4 to move back and forth, and crosshead component 4 exists with piston 6.1
It moves back and forth in working chamber 6, the volume in cylinder block 5 is made to change, so as to realizing inspiration, compression and the row of gas
Out, but since cylinder block 5 can not accomplish to be fully sealed, cause the high pressure gas in working chamber 6 that can let out into inoperative chamber 9
Dew, inoperative chamber 9 are connected to the inlet chamber 4, and the gas for allowing for leaking into inoperative chamber 9 in this way returns in inlet chamber 7 again
It is utilized.
