Abstract
The 'no clearance' high efficiency design scheme for crankshaft driven piston reciprocating compressor is developed on the basis of traditional crankshaft driven piston reciprocating compressor structure. The 'no clearance' high efficiency design scheme features that during exhaust, the piston push the exhaust valve sheet out of the cylinder and into the high pressure area, so that the piston, the exhaust valve sheet and the sucking valve block form one 'no clearance' spatial state. The present invention creates condition for raising the work compression ratio or exhaust efficiency greatly and updates the crankshaft driven piston reciprocating compression technology.
Description
Technical field:
The present invention relates to the piston type compressed machine technology of crank-driven type.
Background technique:
The overwhelming majority in the compressor kind of coming out is the conventional piston compressor by crank-driven at present, it has: make simple, long service life, wait the comprehensive characteristics that other kind compressor can't be by comparison to material is less demanding, this has been a unfailing main cause since its comes out.
Yet its deficiency shows: its working efficiency, promptly work compression ratio or exhaust efficiency are difficult to improve all the time.And bundle is disturbed the main cause that it is difficult to improve before taking a step and is exactly: " volume " efficient that structurally is difficult to improve it, promptly structurally reduce the design efficiency of its " clearance ", and " the no clearance " mentioned in the title of the present invention design can't be imagined especially.
Summary of the invention:
The present invention's purpose:, make the technology of traditional crank-driven type piston reciprocating compressor of market share maximum occur with brand-new looks just in order to solve the problem of above-mentioned this " no clearance " design.
To achieve these goals, intend adopting following technology:
Structurally have: by the reciprocating bent axle of connecting rod driven plunger, it is characterized in that: its piston can head on exhaust valve plate and go out cylinder when exhaust moves, and having formed between piston, exhaust valve plate and the Aspirating valves piece three of this moment does not have " the no clearance " of geometric space state.
Above-mentioned exhaust valve plate is the tip position that is positioned at cylinder by suppressing of spring, and above-mentioned Aspirating valves piece is the open and close at the top outer control suction port of piston.
The present invention's characteristics compared with the prior art:
Because piston of the present invention can head on exhaust valve plate and goes out cylinder, this is just for realizing that " no clearance " of the present invention design created condition, goes forward side by side and has created condition for the work compression ratio or the exhaust efficiency that increase substantially compressor.
Description of drawings:
Fig. 1 has illustrated the embodiment of the present invention in the driving high-power piston compressor of horizontal crankshaft.
Fig. 2 has illustrated the relative position of piston-advance (exhaust) when operation piston, valve and cylinder of Fig. 1 type.
Fig. 3 has illustrated the piston of Fig. 1 type to retreat the relative position of (air-breathing) when operation piston, valve and cylinder.
H: zone of high pressure; W: low pressure area; P: the suction port of piston head; D: AC motor; 1: cylinder cap; 2: spring; 3: exhaust valve plate; 4: taper Aspirating valves piece; 5: piston; 6: cylinder; 7: bent axle; 8: connecting rod; 9: body; 10: set screw.
Embodiment:
Fig. 1 emphasis illustrated crank-driven type compressor " no clearance " design structure in general.
By shown in Figure 2, the piston of WKG working compression exhaust merit (5) wherein, after the pressurized gas that will be compressed into were all clamp-oned zone of high pressure (H), it continued to head on exhaust valve plate (3) itself and goes out cylinder (6), and entered zone of high pressure (H).At this moment, in fact no matter theoretically the geometric space (" clearance ") between piston wherein (5), taper Aspirating valves piece (4) and the exhaust valve plate (3), still said, can both allow it accomplish to be " zero ".Piston (5) is gone out the stroke of cylinder (6), can be controlled at about 1/10th of its effective suction stroke length usually.
By shown in Figure 3, when piston (5) fully during setback cylinder (6), can allow its simultaneously under anticyclonic driving by exhaust valve plate (3) nature of spring (2) location, cylinder (6) top seal is lived.This is, piston wherein (5) converts the working state of doing the air-breathing merit of following current naturally to, because action of pressure, gas in the low pressure area (W), the suction port (P) by piston head and back down the taper Aspirating valves piece (4) of sealing them originally just, enter the suction stroke section in the cylinder (6), along with piston (5) is done the process of air-breathing merit, the space in the suction stroke section is added full the most at last.
Claims (3)
1. " no clearance " efficient design scheme of a crank-driven type piston reciprocating compressor has: by the reciprocating bent axle of connecting rod (8) driven plunger (5) (7),
It is characterized in that:
Can head on exhaust valve plate (3) during piston (5) exhaust operation and go out cylinder (6), form " no clearance " state that does not have geometric space between piston (5), exhaust valve plate (3) and Aspirating valves piece (4) three of this moment.
2. " no clearance " efficient design scheme of a crank-driven type piston reciprocating type formula compressor as claimed in claim 1,
It is characterized in that:
Described exhaust valve plate (3) is the tip position that is positioned at cylinder (6) that suppresses by spring (2).
3. " no clearance " efficient design scheme of a crank-driven type piston reciprocating type formula compressor as claimed in claim 1,
It is characterized in that:
Described Aspirating valves piece (4) is the open and close at the top outer control suction port (P) of piston (5).
