Description
Technical field
It the utility model is related to single screw compressor technical field, and in particular to a kind of single screw compressor interior volume specific ratio
Adjusting mechanism.
Background technology
General single-screw compressor, including a principal screw rotor and the meshed star-wheel group being arranged symmetrically
Part, is inhaled into screw rotor groove by compressed gas, is sealed by spider piece, and 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 that the quilt during rotating a circle
Be sent into compression chamber gas amount it is also different, when nonstandard design is run how much all there are it is following the problem of, there are overcompression, or
Person is under-voltage, and contracting exists, and longtime running consumption is larger.Existing slide valve assembly adjusts not convenient, flexible enough.
Utility model content
The purpose of this utility model is to provide a kind of single screw compressor internal volume rate regulating mechanism, it can be cleverer
The convenient position for adjusting left slider and right sliding block living.
To achieve the above object, the utility model provides following technical solution：
A kind of single screw compressor internal volume rate regulating mechanism, including casing, are provided with a screw rod and two in casing
The Meshing Pair of a planar gaterotors composition being arranged symmetrically, the slide valve assembly for adjusting interior volume specific ratio is also equipped with casing, sliding
Valve module 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
It is connected with outer slide, right piston intracavitary is provided with right piston bar, and right piston bar is connected with inner slide, and outer slide is slided with inner slide
Coordinate, left piston chamber and right piston chamber are connected with oil filling mechanism by solenoid valve respectively, and solenoid valve is used to control left piston chamber/right side
Oil pressure in plunger shaft.
Preferably, inner slide is equipped with sliding slot, and the inner side of outer slide is equipped with spacer pin, and spacer pin is placed in sliding slot, spacing
Pin is so that the scope of interior volume specific ratio is between 1.6-4.0.
The operation principle of the utility model is：Left slider and/or right sliding block are equipped with exhaust outlet, solenoid valve control left piston chamber
With the injection flow of right piston intracavitary and then the movement of left piston bar and right piston bar is driven, realizes left slider and right slide position
Adjust, and then realize the adjusting of interior volume specific ratio.
The beneficial effects of the utility model are：The adjusting left slider and the position of right sliding block that it can be more flexible and convenient.

Block 4 is slidably matched with inner slide 7, and left piston chamber 2 and right piston chamber 5 are connected with oil filling mechanism, solenoid valve by solenoid valve respectively
For controlling the oil pressure in 2/ right piston chamber 5 of left piston chamber.
Inner slide 7 is equipped with sliding slot, and the inner side of outer slide 4 is equipped with spacer pin, and spacer pin is placed in sliding slot, and spacer pin causes
The scope of interior volume specific ratio is between 1.6-4.0.
The operation principle of the utility model is：Solenoid valve control left piston chamber 2 and the injection flow in right piston chamber 5 and then drive
The movement of dynamic left piston bar 3 and right piston bar 6, realizes the adjusting of left slider and right slide position, and then realize interior volume specific ratio
Adjust.
The beneficial effects of the utility model are：The adjusting left slider and the position of right sliding block that it can be more flexible and convenient.
The above is only the preferred embodiment of the utility model, it is noted that for the common skill of the art
For art personnel, on the premise of the utility model technical principle is not departed from, some improvements and modifications can also be made, these change
The scope of protection of the utility model is also should be regarded as into retouching.
