Nova有限公司传统产品的最大压力为60巴,排量为1.5～60标准立方米/小时,转速达3000转/分,其风冷式及水冷式中、高压压缩机系列近两年有了改进。但基本结构保持不变,在原来的产品上提高可靠性,延长维修期,并通过提高转速来增大功率。原有的阀座、弹簧、阀片和升程限止器组成的簧片阀至今还是不错的。但运动件惯量较大,尤其是转速增大时更为麻烦。另一缺点是阀弹簧接触面上不免会有些摩损。改进后用自由移动不锈钢舌型阀,试验结果得到了高转速时效率高,运行安静,无须维护的优点。阀最窄
Nova Co., Ltd. The maximum pressure of the traditional products is 60 bar, displacement of 1.5 to 60 standard cubic meters / hour, the speed of 3000 rev / min, its air-cooled and water-cooled medium and high pressure compressor series has been improved over the past two years . However, the basic structure remains the same, improving the reliability of the original product, extending the maintenance period and increasing the power by increasing the speed. The original seat, spring, valve and lift limit valve composed of reed valve is still good. However, large inertia of the moving parts, especially when the speed increases more trouble. Another disadvantage is the valve spring contact surface will inevitably have some wear and tear. After the improvement, the stainless steel tongue-type valve is freely moved, and the test result shows the advantages of high efficiency, quiet operation and no maintenance at high speed. Valve is the narrowest
