降低片状气阀瓣片刚度,即减小气阀开启所需的压差Δp,可以减小压缩机所需的功率。理论上此时的制冷量也增大。但减小吸气阀瓣片刚度,则可能因气阀关闭滞后而导致制冷剂的泄漏。为了确定在XKB-5型压缩机上降低片状气阀刚度对改善有效指标的可能性,进行了试验。在试验中瓣片宽度由批量生产时的8毫米减至5毫米。列出了有效指标的计算方法。试验表明,在吸气阀和排气阀均
Reducing the stiffness of the flap valve flap, ie reducing the pressure differential Δp required for opening the valve, can reduce the compressor’s required power. In theory, the cooling capacity also increased. However, reducing the stiffness of the suction valve flap may result in refrigerant leakage due to the valve closing hysteresis. In order to determine the possibility of reducing the rigidity of the sheet valve on the XKB-5 compressor to improve the effectiveness of the index, tests were carried out. In the experiment the flap width was reduced from 8 mm at the time of mass production to 5 mm. Lists the calculation of effective indicators. Experiments have shown that the intake valve and the exhaust valve are both
