Description
Technical field
It the utility model is related to compressor field, and in particular to a kind of device of energy simple adjustment cylinder clearance volume.
Background technology
Because the working time of reciprocating compressor and working strength are all special big, in the work of long-time high intensity
Under, fraction of loosening can be all more or less produced between piston rod and piston or piston rod and crosshead, at this moment cylinder and piston
If without clearance volume between, piston and cylinder will produce cylinder accident of hitting, it is serious will fatal crass, and if without remaining
Piston can drain the gas in cylinder in each stroke if gap volume, and at this moment the valve of cylinder inlet and outlet is being opened
When it is all special acutely not steady enough, the damage to valve is bigger.And the gas processed during compressor operating is not
The gas of 100% drying, the vapor in gas liquefies during compression, if since liquid has Incoercibility gas
There is no that if clearance volume liquid hit phenomenon will be produced in cylinder, huge impact is produced to compressor, slightly abnormal punching in short-term
Hitting may be less problematic, but often for a long time and heavier liquid hammer, can make the deformation of compressor, rupture, even broken and direct
Damage compressor.
But the systematic error in actual production, installed the actual clearance volume of later compressor often and originally
There is any discrepancy for the clearance volume of design.When actual clearance volume and design clearance volume come in and go out especially big, it is necessary to reinstall
Piston because the quality of piston especially big installation when it is especially inconvenient.General clearance regulative mode is in the world now
Increase a small cylinder that piston is housed in the cylinder head position of compressor operating cylinder, the piston in small cylinder can pass through peace
Handle or motor outside small cylinder, manually or automatically regulating piston position change the clearance volume of working cylinder.
Utility model content
The technical problem to be solved by the utility model is to provide it is a kind of can simple adjustment cylinder clearance volume device,
The clearance volume in cylinder can effectively be adjusted and reinstalled again without removing whole piston, or pull down the cylinder of working cylinder
Lid is adjusted to install one small cylinder and piston additional, and small cylinder and piston cannot ensure the air-tightness of working cylinder.
Technical problem to be solved in the utility model is realized using following technical solution：
A kind of device of energy simple adjustment cylinder clearance volume, including cylinder, piston only and outer-hexagonal bolt, the gas
Cylinder includes cylinder head and cylinder body, and the piston only is located in cylinder, and the skirt section of piston only is lived equipped with piston pin connection
Stopper rod, piston only head cover end face are equipped with two screw holes.
Two screw holes set on the piston only head cover end face include the first screw hole and the second screw hole, the first screw hole and
Two screw holes are linked to be the center of circle that straight line passes through head cover end face, and symmetrical with the center of circle.
The first screw hole and the internal thread of the second screw hole set on the piston only head cover end face is fine thread.It is described
The cylinder head and cylinder body of cylinder are flanged joint.Head cover of the piston only at the end of the instroke of piston motion
Gap between end face and cylinder channel is clearance volume.
Preferably, can be on the top of piston only when two outer-hexagonal bolts can not meet that clearance volume is adjusted
Lid end face sets two screw holes again, and four screw holes of setting are using the head cover end face center of circle of piston only as basic point annular array
Ensure the mechanical strength of piston only work, four screw holes are the peak that is set on a piston only.
Preferably, in order to preferably protect cylinder, the head cover end face of piston only is arranged to a burnishing surface, cap end
The screw hole set on face changes interior hexagonal double-ended bolt into as counterbore, by outer-hexagonal bolt.
The operation principle of the utility model：Determine that the operating mode of compressor is applicable in model according to the design data of compressor first
Enclose, the clearance volume of standard is then calculated according to the size of job requirement and cylinder piston, it is gentle according to the operating mode scope of application
The size of the cylinder piston determines the total size of compressor redundant gap volume, finally according to the scope of clearance volume and standard clearance volume
Difference range drills through piston correspondingly sized sum number purpose screw hole, and outer-hexagonal bolt is screwed into screw hole by allen wrench,
Exposed outer-hexagonal bolt volume is incorporated in the clearance volume of requirement and recalculates clearance volume, is then held according to new clearance
Product is installed.After installation and debugging finish, adjusted again come the depth of external hex bolts according to the actual conditions of test run
Section, allows its clearance volume to meet production requirement.
The beneficial effects of the utility model are：Accomplish that clearance volume is controllable in the case where not changing working cylinder shape,
The appearance and size of increase compressor is avoided, increases device on original part to control to adjust clearance volume, and is increased without small
Cylinder and piston, allow working space not to be in communication with the outside, and protect the air-tightness of equipment, also can be good in compound compressor
Adapt to.The utility model has the advantages of design science, rational in infrastructure.
