Shut - off valve procedure analysis and simulation of 100mm self - force automatic control valve 自力式自動灌裝閥關閥過程動力學分析與仿真
Development and application of the differential pressure control valve of self - force type in the circulating compressor 自力式差壓控制閥的研制及在循環(huán)壓縮機上的應用
Due to the existence of unbalance self - force in high - speed rotating mechanical device , the vibration accompanying with running machine usually causes noise , which reduces the machine performance or damage the machine 高速旋轉機械由于自身不平衡力的存在,在工作時使機器產(chǎn)生振動,這個振動會產(chǎn)生噪聲,并降低機器性能,甚至損壞機器設備。
