具体实施方式Detailed ways

为了更好地了解本发明的目的、结构及功能，下面结合附图，对本发明一种泵体组件及旋转式压缩机做进一步详细的描述。In order to better understand the purpose, structure and function of the present invention, a pump body assembly and a rotary compressor of the present invention will be described in further detail below with reference to the accompanying drawings.

如图1所示，本发明的旋转式压缩机，包括壳体1、定子2和泵体组件。壳体1内焊接有托板11，定子2和泵体组件均安装在托板11上。定子2驱动泵体组件工作，在泵体组件进行冷媒的压缩。As shown in FIG. 1 , the rotary compressor of the present invention includes a casing 1 , a stator 2 and a pump body assembly. A support plate 11 is welded in the casing 1 , and the stator 2 and the pump body assembly are mounted on the support plate 11 . The stator 2 drives the pump body assembly to work, and the refrigerant is compressed in the pump body assembly.

如图2和图3所示，泵体组件，包括相对转动的泵壳3和曲轴4。曲轴4包括偏心部41，以及设置在偏心部41两端的转轴42。偏心部41设置在泵壳3内，而两转轴42分别贯穿泵壳3。泵壳3内设置有滑片5，滑片5受驱动始终抵接在曲轴4上，从而曲轴4和滑片5将泵壳3内腔分隔为高压腔6和低压腔7。曲轴4设有与低压腔7连通的进气道43，以及与高压腔6连通的出气道44。进气道43和出气道44分别从转轴42延伸至泵壳3外，并与外界连接。As shown in Figures 2 and 3, the pump body assembly includes a relatively rotating pump casing 3 and a crankshaft 4. The crankshaft 4 includes an eccentric portion 41 and a rotating shaft 42 disposed at both ends of the eccentric portion 41 . The eccentric portion 41 is arranged in the pump casing 3 , and the two rotating shafts 42 penetrate through the pump casing 3 respectively. The pump casing 3 is provided with a sliding vane 5 , and the sliding vane 5 always abuts on the crankshaft 4 when driven, so that the crankshaft 4 and the sliding vane 5 divide the inner cavity of the pump casing 3 into a high pressure chamber 6 and a low pressure chamber 7 . The crankshaft 4 is provided with an intake port 43 communicating with the low pressure chamber 7 and an air outlet port 44 communicating with the high pressure chamber 6 . The air inlet 43 and the air outlet 44 respectively extend from the rotating shaft 42 to the outside of the pump casing 3 and are connected to the outside.

为了保证高压腔6和低压腔7的独立，泵体组件与现有技术一致，设有两个密封点。转轴42沿泵壳3内腔同轴设置，偏心部41在柱面设置有与泵壳3内壁线接触的密封母线，作为第一个密封点。而滑片5一端插入泵壳3内壁上的滑槽321内，并受弹簧81驱动沿滑槽321滑移；而滑片5另一端和曲轴4贴近，组成第二密封点。这样通过两个密封点的密封，保证了高压腔6和低压腔7的独立，从而随着滑片5沿曲轴4转动，高压腔6缩小而低压腔7变大，进而高压腔6气体压缩并从出气道44排出，而低压强气体从进气道43进气。In order to ensure the independence of the high-pressure chamber 6 and the low-pressure chamber 7, the pump body assembly is consistent with the prior art, and is provided with two sealing points. The rotating shaft 42 is arranged coaxially along the inner cavity of the pump casing 3 , and the eccentric portion 41 is provided with a sealing busbar on the cylindrical surface that is in line contact with the inner wall of the pump casing 3 as the first sealing point. One end of the sliding vane 5 is inserted into the sliding groove 321 on the inner wall of the pump casing 3, and is driven by the spring 81 to slide along the sliding groove 321; the other end of the sliding vane 5 is close to the crankshaft 4 to form a second sealing point. In this way, through the sealing of the two sealing points, the independence of the high-pressure chamber 6 and the low-pressure chamber 7 is ensured, so as the sliding vane 5 rotates along the crankshaft 4, the high-pressure chamber 6 shrinks and the low-pressure chamber 7 becomes larger, and then the gas in the high-pressure chamber 6 is compressed and compressed. The gas is discharged from the outlet port 44 , and the low-pressure gas is fed in from the intake port 43 .

结合图4所示，为了保证泵体组件的效率，进气道43的出气端和出气道44的进气端并排设置在密封母线的两侧。这样将进气道43的出气端和出气道44的进气端设置在低压腔7和高压腔6的两端，保证缸体冷媒最大程度的压缩。而为了便于加工，进气道43的出气端和出气道44的进气端均设置在偏心部41的端面上。4, in order to ensure the efficiency of the pump body assembly, the air outlet end of the air inlet 43 and the air inlet end of the air outlet 44 are arranged side by side on both sides of the sealing busbar. In this way, the air outlet end of the air intake passage 43 and the air inlet end of the air outlet passage 44 are arranged at both ends of the low pressure chamber 7 and the high pressure chamber 6 to ensure the maximum compression of the cylinder refrigerant. In order to facilitate processing, both the air outlet end of the air inlet passage 43 and the air inlet end of the air outlet passage 44 are arranged on the end face of the eccentric portion 41 .

为了得到所需的压力，出气道44设有调节阀8，当出气道44压力达到设定压力值，调节阀8打开，出气道44排出高压冷媒。调节阀8包括弹簧81和阀芯82，阀芯82受作为弹性件的弹簧81驱动堵住出气道44，当出气道44内冷媒对阀芯82的推力大于弹簧81的拉力，阀芯82退位，出气道44连通。In order to obtain the required pressure, the air outlet 44 is provided with a regulating valve 8. When the pressure of the air outlet 44 reaches the set pressure value, the regulating valve 8 is opened, and the air outlet 44 discharges high-pressure refrigerant. The regulating valve 8 includes a spring 81 and a valve core 82. The valve core 82 is driven by the spring 81 as an elastic member to block the air outlet 44. When the pushing force of the refrigerant in the air outlet 44 to the valve core 82 is greater than the pulling force of the spring 81, the valve core 82 retreats. , the air outlet 44 is connected.

为了便于和外界管路连接，曲轴4固定在托板11上，而泵壳3沿转轴42转动。托板11上开有固定孔111，曲轴4下端的转轴42和固定孔111过盈配合，从而安装固定泵体组件。托板11在固定孔111内还设有气路112，进气道43设置在下端的转轴42内，随转轴42的插接，气路112和进气道43连通。而相应的，出气道44设置在上端的转轴42中。这样，由于曲轴4是固定不动的，便于了上下的管路安装。In order to facilitate connection with external pipelines, the crankshaft 4 is fixed on the support plate 11 , and the pump casing 3 rotates along the rotating shaft 42 . The support plate 11 is provided with a fixing hole 111 , and the rotating shaft 42 at the lower end of the crankshaft 4 is in an interference fit with the fixing hole 111 , so as to install and fix the pump body assembly. The support plate 11 is also provided with an air passage 112 in the fixing hole 111 , and the air passage 43 is arranged in the lower end of the rotating shaft 42 . Correspondingly, the air outlet 44 is arranged in the rotating shaft 42 at the upper end. In this way, since the crankshaft 4 is fixed, it is convenient to install the upper and lower pipelines.

为了便于制作泵壳3，泵壳3包括内缸32，供滑片5滑动的滑槽321贯穿滑内缸32侧壁。内缸32两端分别通过螺钉连接有盖板33，盖板33开有套设在转轴42外的定位孔。内缸32外套设固定在转子31内。转子31为磁钢片叠压形成，转子31开具有磁钢槽，磁钢槽内放磁钢，从而通过磁钢切割磁感线，定子驱动转子31并带动内缸32和滑片5转动。In order to facilitate the manufacture of the pump casing 3 , the pump casing 3 includes an inner cylinder 32 , and the sliding groove 321 for sliding the sliding vane 5 runs through the side wall of the sliding inner cylinder 32 . Two ends of the inner cylinder 32 are respectively connected with a cover plate 33 by screws, and the cover plate 33 is provided with a positioning hole sleeved outside the rotating shaft 42 . The inner cylinder 32 is externally arranged and fixed in the rotor 31 . The rotor 31 is formed by lamination of magnetic steel sheets. The rotor 31 has a magnetic steel slot, and the magnetic steel is placed in the magnetic steel slot, so that the magnetic field lines are cut by the magnetic steel. The stator drives the rotor 31 and drives the inner cylinder 32 and the sliding vane 5 to rotate.

这样将泵体组件内置于转子31中，组成全新结构，进一步节约压缩机空间。In this way, the pump body assembly is built into the rotor 31 to form a new structure, which further saves the space of the compressor.
