Description

迴轉式壓縮機改良Rotary compressor improvement

本創作係以有關迴轉式壓縮機之改良，旨在提供一種可確實隔離高低壓之迴轉式壓縮機。This creation is based on the improvement of rotary compressors and aims to provide a rotary compressor that can effectively isolate high and low pressure.

按，一般用以壓縮冷媒並使其於迴路內循環之電動壓縮機，基本上係藉由直流馬達帶動所聯結的壓縮機制動作，進而達到將冷媒進行壓縮與循環的動作效果；其依照內部壓縮機制之不同，目前常見有包括：迴轉式壓縮機(rotary compressor)、渦捲式壓縮機(scroll compressor)及螺旋式壓縮機(screw compressor)等機型。According to the electric compressor, which is generally used for compressing the refrigerant and circulating it in the circuit, basically the action of the compression mechanism connected by the DC motor is actuated, thereby achieving the effect of compressing and circulating the refrigerant; The mechanism is different, including rotary compressors, scroll compressors, and screw compressors.

其中，渦捲式壓縮機因加工性相對不易故有成本較高之問題，雖然迴轉式壓縮機與螺旋式壓縮機都是經由改變壓縮腔的容積來完成壓縮過程，但由於迴轉式壓縮機採用了更為簡潔的壓縮方式，巧妙地避免了螺旋式壓縮機無法根除的軸向受力偏移、餘隙容積和種種內部洩漏等問題，使得設備的可靠性和效率同時得到大幅度提升，因此獲得相對較高的市場佔有率。Among them, the scroll compressor has a relatively high cost due to relatively low processability. Although both the rotary compressor and the screw compressor complete the compression process by changing the volume of the compression chamber, the rotary compressor is used. The simpler compression method cleverly avoids the problems of axial force displacement, clearance volume and various internal leakage that cannot be eradicated by the screw compressor, so that the reliability and efficiency of the equipment are greatly improved at the same time. Get a relatively high market share.

原則上，迴轉式壓縮機係以一偏心軸置於馬達轉子中心，如第1圖所示，迴轉式壓縮機10係在殼體11的內部，安裝馬達(包含轉子121及定子122)、偏心軸13以及汽缸14，當偏心軸13隨著馬達轉子121的旋轉而於汽缸14內迴轉時，即與汽缸壁形成一系列體積不同的等壓壓縮腔(包含第一腔室15和第二腔室16)，進而達到逐轉壓縮冷媒之目的。In principle, the rotary compressor is placed at the center of the motor rotor with an eccentric shaft. As shown in Fig. 1, the rotary compressor 10 is mounted inside the casing 11, and is equipped with a motor (including the rotor 121 and the stator 122), and is eccentric. The shaft 13 and the cylinder 14 form a series of equal volume compression chambers (including the first chamber 15 and the second chamber) when the eccentric shaft 13 rotates within the cylinder 14 with the rotation of the motor rotor 121, that is, with the cylinder wall. Room 16), in order to achieve the purpose of compression-by-rotation of the refrigerant.

惟，上述習知迴轉式壓縮機中，該汽缸14與殼體11間僅利用焊接方式固定，而該第一腔室15與第二腔室16間並無密封元件做為區隔；且當迴轉式壓縮機之殼體傾倒時，該第二腔室內之冷凍油會流至該第一腔室，且當迴轉式壓縮機之殼體回復正常使用位置時，流至該第一腔室之冷凍由無法快速迴流至第二腔室，會影響整體壓縮機之實際運作效能，尤其會降低壓縮機之效率。再者，汽缸14與殼體11間利用焊接方式固定時，為了熔化汽缸14及殼體11於焊接點處的金屬，焊接常要超過1000℃。焊接時過高的溫度常引起汽缸14的熱變型，對於汽缸14的內壁微米級的精度影響甚大，進而產生汽缸漏或卡死等問題，尤其是用於體積較小之迴轉式壓縮機，上述熱變型之問題完全無法避免。However, in the above conventional rotary compressor, the cylinder 14 and the housing 11 are fixed only by welding, and there is no sealing element between the first chamber 15 and the second chamber 16 as a partition; When the casing of the rotary compressor is dumped, the refrigeration oil in the second chamber flows to the first chamber, and when the casing of the rotary compressor returns to the normal use position, it flows to the first chamber. The freezing cannot be quickly returned to the second chamber, which will affect the actual operating efficiency of the overall compressor, especially the efficiency of the compressor. Further, when the cylinder 14 and the casing 11 are fixed by welding, in order to melt the metal of the cylinder 14 and the casing 11 at the welding point, the welding often exceeds 1000 °C. Excessive temperature during welding often causes thermal deformation of the cylinder 14, which has a great influence on the accuracy of the micro-scale of the inner wall of the cylinder 14, thereby causing problems such as cylinder leakage or jamming, especially for a small-sized rotary compressor. The problem of the above thermal variants is completely unavoidable.
