Description
Technical field
The present invention relates to a kind of anti-injection gas blowby structure of two-spool compressor intermediate plate.
Background technology
In totally-enclosed two-spool compressor, as depicted in figs. 1 and 2, intermediate plate is provided between casing top half and lower cylinder
1, intermediate plate 1 is provided with vertical through hole connection casing top half and lower cylinder, and the vertical through hole constitutes the cold of casing top half and lower cylinder
Matchmaker's jet 11, the side of intermediate plate 1 is communicated with the coolant injection passage 12 of intermediate plate vertical through hole, and liquid or gaseous coolant are logical
Overspray passage 12 and jet 11 to casing top half and lower cylinder injection, are realized the refrigeration of compressor and are heated respectively.In the middle of this
It is identical with the position angle of jet 11 of lower cylinder for casing top half on plate 1, while to casing top half and lower cylinder injection refrigerant, in
Between the opening and closing of plate jet about 1 sprayed with intermediate plate 1 when being moved mainly by casing top half piston 2 and lower steam-cylinder piston 3
The change in location of mouth 11.When compressor crank shaft band piston 2,3 is rotated, there is certain angular range, in the angular range
It is interior, as shown in figure 1, in the case of refrigerant normal injection, due to the change of casing top half piston 2 and the lower position of steam-cylinder piston 3, in
Between the upper and lower end face of plate 1 a jet open, another jet close；As shown in figure 3, but when casing top half piston 2 is with
Steam-cylinder piston 3 moves to a certain position, the jet 11 of the upper and lower end face of intermediate plate 1 is opened simultaneously when, now elevated pressures cylinder
In refrigerant lower pressure cylinder can be flowed into by the passage of jet 11, form the gas blowby between casing top half and lower cylinder, alter
Gas causes the input power of compressor to increase extremely, has a strong impact on the performance of compressor.
The content of the invention
The technical problems to be solved by the invention are to provide a kind of anti-injection gas blowby structure of two-spool compressor intermediate plate,
This structure overcomes the defect of conventional intermediate plate jet, effectively prevent the gas blowby between compressor casing top half and lower cylinder,
The input power of compressor is reduced, compressor performance is improve.
In order to solve the above technical problems, the anti-injection gas blowby structure of two-spool compressor intermediate plate of the present invention is included located at pressure
Intermediate plate, casing top half piston and lower steam-cylinder piston between contracting machine casing top half and lower cylinder, the casing top half piston and lower cylinder
Piston is located at the middle plate top surface and bottom surface respectively, and inclined via-hole is opened up between the top surface of the intermediate plate and bottom surface, described
Casing top half piston and lower steam-cylinder piston at least one cover the inclined via-hole of the intermediate plate.
Further, the center line of above-mentioned intermediate plate inclined via-hole and the intermediate plate Axis Cross.
Because the anti-injection gas blowby structure of two-spool compressor intermediate plate of the present invention employs above-mentioned technical proposal, i.e. this knot
Structure is included located at the intermediate plate between compressor casing top half and lower cylinder, casing top half piston and lower steam-cylinder piston, the casing top half
Piston and lower steam-cylinder piston are located at the middle plate top surface and bottom surface respectively, are opened up between the top surface of the intermediate plate and bottom surface and inclined
Oblique through hole, the casing top half piston and lower steam-cylinder piston at least one cover the inclined via-hole of the intermediate plate.This structure overcomes
The defect of conventional intermediate plate jet, effectively prevent the gas blowby between compressor casing top half and lower cylinder, reduce compression
The input power of machine, improves compressor performance.

Specific embodiment
As shown in Figure 4 and Figure 5, the anti-injection gas blowby structure of two-spool compressor intermediate plate of the present invention includes being located at compressor
Intermediate plate 1, casing top half piston 2 and lower steam-cylinder piston 3 between casing top half and lower cylinder, the casing top half piston 2 and lower cylinder
Piston 3 is located at the top surface of the intermediate plate 1 and bottom surface respectively, and inclined via-hole 13 is opened up between the top surface of the intermediate plate 1 and bottom surface,
The casing top half piston 2 and lower steam-cylinder piston 3 at least one cover the inclined via-hole 13 of the intermediate plate 1.
Further, the center line of above-mentioned intermediate plate inclined via-hole 13 and the Axis Cross of the intermediate plate 1.
This structure by the optimization to intermediate plate jet, two jets up and down of inclined via-hole 13 on intermediate plate 1
131st, 132 position angles are different so that upper in any one angle, intermediate plate 1 when bent axle band piston 2,3 is rotated
Lower two jets 131,132, all without opening simultaneously, are so not in that gas blowby causes the input power of compressor to increase extremely
Big situation.There is certain position angle in two jets 131,132 centers and the axis of intermediate plate 1 up and down on intermediate plate 1
Change, in the case of normal injection, as shown in figure 4, due to upper and lower steam-cylinder piston 2, the change of 3 positions, the upper and lower end face of intermediate plate 1
Two jets, 131,132 1 unlatchings, a closing.In critical localisation, as shown in figure 5, two sprays up and down on intermediate plate 1
Loophole 131,132 is covered by casing top half piston 2 and lower steam-cylinder piston 3 simultaneously, and two jets 131,132 are closed, therefore are not deposited
In the possibility of upper and lower cylinder gas blowby, so as to overcome the defect of conventional intermediate plate gas blowby.
