Description
Technical field
The present invention relates to hydrogenation stations technical field more particularly to a kind of pressure tune for hydrogenation stations high pressure hydrogen compressor
Displacements of cylinders.
Background technique
The size of each stage pressure influences the stress condition of piston in compressor, is finally reflected in piston rod in the course of work
In can bear, adjust each stage pressure seek to reduce piston force.Meanwhile the ratio size of each stage pressure influence again it is compressed
Delivery temperature.After the completion of compressor design manufacture, occur actual pressures at different levels in commissioning process and design pressure have it is certain
Deviation.Existing pressure adjusts cylinder and has the disadvantages that：It needs repeatedly to be adjusted when adjusting cylinder pressure, Fang Keda
To ideal atmospheric pressure value, and pressure adjusts cylinder to be connected to the mode on cylinder unreliable.
Summary of the invention
The purpose of the present invention is to solve disadvantages existing in the prior art, and the one kind proposed is used for hydrogenation stations high pressure
The pressure of hydrogen gas compressor adjusts cylinder.
To achieve the goals above, present invention employs following technical solutions：
A kind of pressure adjusting cylinder for hydrogenation stations high pressure hydrogen compressor, it is characterised in that：Including level-one cylinder, in level-one
One secondary cylinder of side mating connection of cylinder, in the opposite side mating connection three-stage cylinder of level-one cylinder, in secondary cylinder
One adjusting cylinder of cylinder body side mating connection, is arranged a flange, flange is fixed by bolt and cylinder body on adjusting cylinder
Cooperation, adjusts cylinder and is connected to by adjustment hole with secondary cylinder, and a regulating piston bar is arranged in cylinder adjusting, lives adjusting
Screw thread is arranged in one end of stopper rod, is socketed a tight split nut, tight split nut and adjusting in one end of regulating piston bar setting screw thread
Cylinder corresponding matching.
Preferably, the regulating piston bar is T font structure, and scale is arranged in the side of the regulating piston bar.
Preferably, one end of regulating piston bar is provided with one group of O-ring, O-ring and the adjusting cylinder inner wall slide
Cooperation.
Preferably, a gasket is set between flange and cylinder body.
The advantage of the invention is that：The present invention and traditional gasket thickness by between adjusting air valve gasket thickness, cylinder
Degree adjusts pressure method and compares, and adjustable pressure limit is big；Compared with existing pressure adjusts cylinder, institute can be directly set
The pressure needed, and the connection type of this adjusting cylinder is relatively reliable.
Detailed description of the invention
Fig. 1 is basic structure schematic diagram of the invention.
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 pressure for hydrogenation stations high pressure hydrogen compressor provided by the invention adjusts cylinder, it is special
Sign is：Including level-one cylinder 1, in one secondary cylinder 2 of the side of level-one cylinder 1 mating connection, in the another of level-one cylinder 1
Side mating connection three-stage cylinder 3, in 4 side of cylinder body of secondary cylinder 2 mating connection, one adjusting cylinder 5.
One flange 8 is set on adjusting cylinder 5, and it is logical to adjust cylinder 5 by bolt 12 and 4 secure fit of cylinder body for flange 8
Toning knothole 6 is connected to secondary cylinder 2, a regulating piston bar 7 is arranged in cylinder 5 adjusting, the regulating piston bar 7 is T
Font structure is provided with one group of O-ring 11 at the T-type end of regulating piston bar 7, and O-ring 11 and 5 inner wall of adjusting cylinder slide
Cooperation is arranged screw thread in the bar portion of regulating piston bar 7, a tight split nut 9 is socketed on the bar portion screw thread of regulating piston bar 7,
Tight split nut 9 and adjusting 5 corresponding matching of cylinder, tight split nut 9 is to secured adjusted piston rod 7.
One gasket 10 is set between flange 8 and cylinder body 4, plays sealing function, is arranged in the side of regulating piston bar 7
Tight split nut 9 need to be only threaded to the scale when needing to be arranged a pressure value of cylinder by scale.
The working principle of the invention：Regulating piston bar 7 can be moved adjusting in cylinder 5, when regulating piston bar 7 is far from cylinder
When body 4, the total measurement (volume) of split-compressor cylinder is increased, but effective swept volume of secondary cylinder 2 is constant, when secondary cylinder 2
When air-breathing, the clearance volume gas for participating in expansion is more, and the gas sucked in is just few, is equivalent to and reduces secondary cylinder 2
Diameter, effective swept volume of secondary cylinder 2 reduce, effective swept volume of level-one cylinder 1 divided by secondary cylinder 2 effective work
Make the resulting pressure ratio of volume to become larger, it is corresponding in the case where the admission pressure of level-one cylinder 1 is constant, level-one cylinder 1
Pressure at expulsion becomes larger, conversely, the pressure ratio between level-one cylinder 1, secondary cylinder 2 becomes smaller when regulating piston bar is close to cylinder body 4,
It is corresponding in the case where the admission pressure of level-one cylinder 1 is constant, the pressure at expulsion of level-one cylinder 1 also becomes smaller, by above
The pressure at expulsion of level-one cylinder 1 can be controlled in reasonable range by adjusting.
