Summary of the invention
The utility model mainly is to solve the technical problem that existing in prior technology noise height, wearing and tearing cause vibration etc. greatly, easily, and the compressor block that a kind of noise is low, wearing and tearing are little, operate steadily is provided.
Above-mentioned technical problem of the present utility model is mainly solved by following technical proposals: a kind of new type compressor body, body comprises the crankshaft hole that is arranged on the middle part, a side that it is characterized in that described body is provided with the exhaust die cavity, the junction surface of body and compressor valve board is provided with a secondary exhaust die cavity, by the secondary exhaust port passage that links to each other, secondary exhaust die cavity is corresponding with noise reduction inlet hole and noise reduction air outlet hole on the compressor valve board between described exhaust die cavity and the secondary exhaust die cavity.Gas flows in cylinder, produces impact owing to the reason of pressure can form turbulent flow in compressor with the casing wall collision, the noise that the exhaust die cavity can reduce to impact is set, and makes the flow direction of air-flow by the secondary exhaust port in order.Because the noise reduction air outlet hole is greater than the noise reduction inlet hole, so the noise reduction inlet hole plays the effect of air inlet restriction, make the kinetic energy of the air-flow by secondary exhaust noise silencing hole reduce, played the effect that reduces noise, reduced the loss power of compressor simultaneously.
As preferably, described crankshaft hole upper-end surface is provided with the annular groove that be used for mounting plane bearing concentric with this crankshaft hole.Annular groove is used to put special plane bearing, reduces the friction factor of bent axle and body, reduces compressor power input, the coefficient of enhancing product performance.
As preferably, the both sides of described annular groove are respectively equipped with spacing hole, and the part of this spacing hole is in the bottom of annular groove; Part is in the outside of annular groove.The plane bearing of being located in this annular groove is provided with two spacing preiections corresponding with this spacing hole, has prevented the lateral movement of plane bearing.Because the existence of this spacing hole, lubricant oil can enter in the plane bearing more smoothly.
As preferably, the aperture of the noise reduction air outlet hole on the described compressor valve board be noise reduction inlet hole aperture 2-4 doubly.The aperture ratio of noise reduction air outlet hole and noise reduction inlet hole is excessive, and is then slow excessively by the air-flow in secondary exhaust noise silencing hole, influences compressor horsepower, if the aperture ratio of noise reduction air outlet hole and noise reduction inlet hole is too small, then erasure effect reduces.The a large amount of experiment of this organization plan structure is reached a conclusion, and it is best that the aperture of noise reduction air outlet hole is that the 2-4 in noise reduction inlet hole aperture doubly advances effect.
The beneficial effect that brings of the present utility model is, solved the technical problem that existing in prior technology noise height, wearing and tearing cause vibration etc. greatly, easily, the compressor block that realized that a kind of noise is low, wearing and tearing are little, operates steadily.
