Description
Technical field
The present invention relates to single screw compressor technical field, and in particular to a kind of single screw compressor interior volume specific ratio regulation
Mechanism.
Background technology
In general single-screw compressor, including a principal screw rotor and the meshed star-wheel group being arranged symmetrically
Part, it is inhaled into screw rotor groove by compressed gas, is sealed by spider piece, with the rotation of rotor, compression stroke gradually reduces,
Discharged when reaching suitable volume from exhaust outlet.
Volume compression ratio (volume compression ratio), in the field of general compressor, refers to fluid and is pressed
The degree of contracting, that is, volume of the fluid when export mouth is flowed out, divided by maximum encapsulating volume, are that working conditions of compressor determines
In the case of, when compressor produces overcompression or under-voltage contracting, it can all cause the rising of compression horsepower, Energy Efficiency Ratio reduces.
What universal helical-lobe compressor used now is all the slide-valve gear for determining interior volume specific ratio, offers on guiding valve and is radially vented
Mouthful, guiding valve is in different positions within the compressor, and the length that screw rod is sealed is also different, so as to the quilt during rotating a circle
It is also different to be sent into the amount of compression chamber gas, how much the problem of following all be present when nonstandard design is run, overcompression be present, or
Person is under-voltage, and contracting is present, and longtime running consumption is larger.Existing slide valve assembly regulation is not convenient, flexible enough.
The content of the invention
It is an object of the invention to provide a kind of single screw compressor internal volume rate regulating mechanism, and it can be more flexibly square
Just regulation left slider and the position of right sliding block.
To achieve the above object, the present invention provides following technical scheme：
A kind of single screw compressor internal volume rate regulating mechanism, including casing, a screw rod is installed in casing and two right
Claim the Meshing Pair of the planar gaterotors composition of arrangement, the slide valve assembly for adjusting interior volume specific ratio, guiding valve group are also equipped with casing
Part includes left piston chamber, right piston chamber, outer slide and inner slide, and left piston intracavitary is provided with left piston bar, left piston bar with it is outer
Sliding block is connected, and right piston intracavitary is provided with right piston bar, and right piston bar is connected with inner slide, and outer slide slides with inner slide matches somebody with somebody
Close, left piston chamber and right piston chamber are connected with oil filling mechanism by magnetic valve respectively, and magnetic valve is used to control left piston chamber/right work
Fill in the oil pressure of intracavitary.
Preferably, inner slide is provided with chute, and the inner side of outer slide is provided with spacer pin, and spacer pin is placed in chute, spacing
Pin causes the scope of interior volume specific ratio to be between 1.6-4.0.
The present invention operation principle be：Left slider and/or right sliding block are provided with exhaust outlet, solenoid valve control left piston chamber and the right side
The motion of injection flow and then driving left piston bar and right piston bar in plunger shaft, realizes left slider and the tune of right slide position
Section, and then realize the regulation of interior volume specific ratio.
Beneficial effects of the present invention are：The regulation left slider and the position of right sliding block that it can be more flexible and convenient.

It is slidably matched with inner slide 7, left piston chamber 2 and right piston chamber 5 are connected with oil filling mechanism by magnetic valve respectively, and magnetic valve is used for
Control the oil pressure in the right piston chamber 5 of left piston chamber 2/.
Inner slide 7 is provided with chute, and the inner side of outer slide 4 is provided with spacer pin, and spacer pin is placed in chute, and spacer pin causes
The scope of interior volume specific ratio is between 1.6-4.0.
The present invention operation principle be：Solenoid valve control left piston chamber 2 and the injection flow in right piston chamber 5 and then a driving left side
The motion of piston rod 3 and right piston bar 6, realizes the regulation of left slider and right slide position, and then realizes the regulation of interior volume specific ratio.
Beneficial effects of the present invention are：The regulation left slider and the position of right sliding block that it can be more flexible and convenient.
Described above is only the preferred embodiment of the present invention, it is noted that is come for those skilled in the art
Say, without departing from the technical principles of the invention, some improvements and modifications can also be made, these improvements and modifications also should
It is considered as protection scope of the present invention.
