Description
Technical field
The present invention relates to the clearance amount regulating systems on a kind of reciprocating compressor.
Background technology
The capacity of industrial reciprocating compressor is usually the maximum volume flow or recent device according to needed for device
Flow needed for possible dilatation selects, generally with certain surplus, due to change (inlet pressure, the temperature of entry condition
Degree etc.), the demand of technological process or gas consumption equipment change, when air consumption is less than the capacity of compressor, just need to pressure
Contracting machine carries out tolerance adjusting, so that the discharge capacity of compressor adapts to the requirement of air consumption, keeps the pressure in pipe network, clearance tolerance tune
Section system is to be known as tolerance clearance adjusting by changing the size of reciprocating compressor clearance volume to adjust the capacity of compressor.
Clearance is adjusted while compressor tolerance is changed, thermal procession, exhaust temperature to working medium in compressor power consumption, cylinder
Degree, machine vibration, main parts size stress all generate benefit.The system mainly has hydraulic oil unit（Containing control system）, perform machine
Structure, air leakage detection system composition.It is suitable for large scale industry reciprocating compressors.
Clearance amount regulating system is used in the energy-saving equipment on industrial large-sized reciprocating compressor, mainly there is control system
System, executing agency, air leakage detection system composition, energy-saving effect is notable, can reduce compressor temperature, reduces the vibration of compressor.
It is incomplete in the design process of executing agency since the structure to reciprocating compressor and operating mode understand not enough, there is peace
, there is phenomenon of rupture in full hidden danger.
1）It is easy to cause piston, rod fracture
Clearance amount regulating system actuator design is cylinder (volume cylinder), oil cylinder two parts form, and cylinder is divided into ante-chamber (nothing
Bar) volumetric void fraction chamber, back cavity (having bar) oil cylinder control chamber, oil cylinder is divided into long pressure chamber (having bar), discharge chamber (no bar), after cylinder
Chamber (having bar) control chamber is when failure or system pressure raise, cylinder piston is moved to fully closed direction, and at this moment oil cylinder piston is gone to
During the fully closed limit, oil cylinder control chamber is also working at this time, piston rod is made infinitely to stretch, piston and piston rod are seriously sheared, caused
Oil cylinder piston, rod fracture, control chamber can generate variation of joining when control, and variation of joining for a long time also easily generates
Component fatigue causes to be broken.
2）Hit cylinder
If piston, rod fracture, cylinder piston, which is directly entered in compressor, to be caused to hit cylinder.
3）Oil gas is mutually gone here and there
Since the frame mode of clearance cylinder (cavity volume) is front volume cylinder (no bar), below hydraulic control chamber, if piston
Sealing ring failure will result in oil gas and mutually go here and there, and control chamber is that high pressure oil easily enters compressor, oil gas is caused mutually to go here and there, once it is oily
Mutually string will lead to major accident to gas.
4）Oil hydraulic system problem
Since the frame mode of clearance cylinder (volume cylinder) is, before hydraulic control chamber behind cavity volume, if piston packing
Failure will result in control oil and be discharged from exhaust stack, and cylinder structure ante-chamber is that long cavity (bar), rear cylinder are discharge chambers, if close
The long cavity control oil of seal failure can enter discharge chamber, fuel tank control oil can be caused to largely reduce, leakage will seriously cause hydraulic pressure
System can not work.
The content of the invention
Its purpose of the invention is that the clearance air volume regulating device provided on a kind of reciprocating compressor, solves clearance
There is piston, rod fracture, hits cylinder, the problem of oil gas is mutually gone here and there, oil hydraulic system oil leak in tolerance in adjusting, have it is stable,
The characteristics of safe and reliable.
Realize above-mentioned purpose and the technical solution taken, the clearance air volume regulating device on a kind of reciprocating compressor, bag
Control system, executing agency, air leakage detection system are included, the executing agency includes oil cylinder, oil cylinder one end connection A control mouths, oil
For the cylinder other end through flanged joint cylinder, flange is equipped with B control mouths, is equipped with piston in oil cylinder, piston is located at in-oil cylinder one end
Equipped with left piston, the rodless cavity of left piston and oil cylinder one end is A control chambers, and the rod chamber of left piston and the oil cylinder other end is controlled for B
Chamber processed, A control chambers connection A control mouths, B control chambers connection B control mouths, one end that the piston is located in cylinder is equipped with right work
Plug, one end rod chamber in right piston and cylinder are discharge chamber, and right piston and the other end rodless cavity in cylinder are clearance chamber, institute
Left piston is stated equipped with cylinder seal, flange and piston junction are equipped with piston rod seals, piston rod be set to two-stage sealing,
Centre is equipped with oil groove, and right piston is equipped with cylinder seal circle.
Advantageous effect
The present invention has the following advantages compared with prior art.
The present invention independently separates cylinder, oil cylinder and does not set common pressure chamber, has oil cylinder AB chambers to do control chamber, cylinder (volume cylinder) is only
As volumetric void fraction, cylinder back cavity is set to discharge chamber is in line to be detected on the spot, is done in oil cylinder (rod chamber) at discharge chamber sealing
Two-stage seals, and leads directly to fuel tank equipped with oil groove among sealing, if cylinder seal Failure Control oil can only return to fuel tank, accomplishes
Oil-gas Separation has oil cylinder to do servo adjusting, and the phenomenon of joining caused by having prevented when common pressure chamber, control chamber are in control ensures
Due to fracture caused by fatigue.
Description of the drawings
The invention will be further described below in conjunction with the accompanying drawings.
Fig. 1 is the structure diagram of the system.
Specific embodiment
Clearance amount regulating system on a kind of reciprocating compressor, including control system, executing agency, gas leakage detection system
System, as shown in Figure 1, the executing agency includes oil cylinder 1,1 one end of oil cylinder connection A control mouths 2,1 other end of oil cylinder connects through flange 4
Cylinder 5 is connect, flange 4 is equipped with B control mouths 7, and piston 3 is equipped in oil cylinder 1, and one end that piston rod 3 is located in oil cylinder 1 is equipped with left work
The rodless cavity of plug 6, left piston 6 and 1 one end of oil cylinder is A control chambers 8, and left piston 6 and the rod chamber of 1 other end of oil cylinder control for B
Chamber 9, A control chambers 8 connect A control mouths 2, and B control chambers 9 connect B control mouths 7, and one end that the piston rod 3 is located in cylinder 5 is set
There is right piston 10, right piston 10 is discharge chamber 11, right piston 10 and the other end in cylinder 5 with one end rod chamber in cylinder 5
Rodless cavity is clearance chamber 12, and the left piston 6 is equipped with cylinder seal 13, and flange 4 is equipped with piston rod with 3 junction of piston rod
Sealing ring 16, right piston 10 are equipped with cylinder seal circle 15.
