The reliability and stability that can be improved compressor are arranged in sample.
Compressor in above-described embodiment can be also used for technical field of refrigeration equipment, i.e., another party according to the present invention
Face provides a kind of refrigeration equipment.The refrigeration equipment includes compressor, and compressor is the compressor in above-described embodiment.Wherein,
The refrigeration equipment is refrigerator.
Specifically, using the slide valve assembly of the structure, it is convenient for the independent machine-shaping of slide valve assembly, compressor assembly will be optimized
Assembly technology.When compressor Smaller load run when, bypassed by slide valve partial shrinkage gas indoor to piston, into
And realize that the continuous transfiguration of compressor is adjusted, and is finally reached the purpose of efficient operation.Wherein, sliding of the slide valve in mounting hole
Journey needs reciprocating motion and one side position of spring to slide valve to carry out a fixing limit, and the selection of limit method determines compression
Thermomechanical components assemble difficulty and craftsmanship, will further enhance the craftsmanship of slide valve using the limit method of the sliding valve structure
With the lean effect for improving compressor.
According in one embodiment of the application, limit point carries out position restriction to the spring of slide valve side, and subtracts
Lack limit of the limit plunger part to slide valve assembly, generates the beneficial effect of optimization design of part composition.
In addition, proposing the alternate embodiments of straight-through structure component (tube-in-tube structure), design of part is formed and is led directly to
It is suitable to limit plug construction package.It, can be to being installed in cylinder block but since slide valve assembly can be integrally machined molding by other factory
Hole machined required precision reduces.Therefore reach the beneficial effect of optimization compressor assembly assembly technology.
The purpose of technical solution provided by the present application is the transfiguration regulation technology in order to realize reciprocating-piston compressor, and excellent
Change the composed structure of slide valve assembly.Bleed hole on the structure of mounting hole and pump housing cover assembly in cylinder block, that is, rack
Structure (exhaust bypass road).Wherein the structure of mounting hole of cylinder block belongs to the through-hole structure for being parallel to cylinder, relative to cylinder
That is the minimum distance (wall thickness) of piston chamber need to guarantee the reliability of pump body structure, and general minimum thickness is greater than or equal to 2mm.
There are by-pass prot vertical connection, connection of first by-pass prot between mounting hole and cylinder holes between cylinder and mounting hole
Section, Connectivity Section of second by-pass prot between mounting hole and air-breathing cavity, wherein the first by-pass prot and the second by-pass prot are coaxial.
If spring original state is in compression or former long status, slide valve one end is spring, and the other end must be with exhaust high pressure
There is that side cavity of spring to be connected to air-breathing low pressure chamber for chamber connection, slide valve.Slide valve is the moving component in mounting hole.When
When slide valve initial position is located on the left of by-pass prot, spring need to be located at right positions.Wherein the side of spring is sliding valve structure, another
Side is spring limiting structure.
When the mounting hole of cylinder block, own as sliding valve movement contact channel when, wanted with the cooperation precision of slide valve
Ask higher, when cylinder block mounting hole be left and right straight-through structure when, spring retainer side need individual limit plunger part into
Row spring retainer, wherein limit plunger part can be rubber plug or metal closures, and the assembly method with mounting hole can be screw-type or glue
Connect formula.Further, when cylinder block mounting hole is non-straight-through structure, non-put-through channel can be formed from limit method (such as
Structure shown in Fig. 3), limit plunger part is simplified to the limit method of slide valve assembly.
Further, due to the mounting hole of cylinder block, own as sliding valve movement contact channel when, with slide valve
Cooperate required precision higher, processing is also corresponding more difficult.Therefore the alternate embodiments (such as Fig. 4 structure) proposed, slide valve, bullet
Spring, sleeve constitute integrated slide valve assembly structure.It is used directly for installation in cylinder block, will be reduced to being installed in cylinder block
The difficulty of processing in hole.Its assembly process process also will be enhanced.
Reciprocating-piston compressor mainly realizes energy adjustment by startup-shutdown mode at present, but due to each start process
It requires to re-establish pressure difference, and the process for re-establishing pressure difference more consumes energy.Therefore the application devises a kind of with change
The compressor for holding structure adjusts its transfiguration in underload, to reduce on-off frequency, reaches more energy-efficient effect.
The compressor has the function that capacity regulating is carried out with load variations.Its specific implementation is to utilize suction and discharge
Pressure difference constitutes dynamic equilibrium with elastic force suffered by slide valve assembly, is moved back and forth in mounting hole with this spool control valve (negative in height
Close by-pass prot when lotus, when underload opens by-pass prot), and then realize that the varying capacity under different load is adjusted.
For Fig. 1, slide valve is in the position for blocking the first by-pass prot and the second by-pass prot communicating passage completely, i.e., at this time
In full load condition.Its slide valve right end is spring, and the active force between spring force and pressure difference constitutes the relationship of relative equilibrium.Its
The right end of spring is limit plug structure, and effect is to fix the position on the left of spring.
For Fig. 3, in the processing of cylinder block mounting hole, using non-interconnected processing method.Its own ladder is constituted
The structure limited on the left of spring, relative to shown in Fig. 1, structure reduces limit plunger part.Ladder is limited for it, is still had
Inner aperture needs to be connected to the air-breathing cavity of (in shell) on the outside of cylinder block, the reason is that guarantee slide valve right side always with suction
The connection of gas cavity.
For shown in Fig. 5 and Fig. 6, cylinder block is straight-through structure, but can not do the requirement of internal accuracy, phase is processed
To easy.Its slide valve and mounting hole have been separately formed slide valve assembly structure, and wherein mounting hole is processed by 45# steel or casting aluminium material,
Difficulty of processing will be simplified.Its slide valve assembly is assembled then at cylinder block, and then realizes the function that transfiguration is adjusted.
Wherein, through type cylinder holder structure can directly constitute the group for realizing transfiguration function with limit plunger, slide valve, spring cooperation
Part.Through type cylinder holder structure also can constitute required function component with slide valve assembly assembly in Fig. 4.Non- through type cylinder block knot
Structure can directly constitute the component for realizing transfiguration function with slide valve, spring.
