摘要
双圆弧斜齿齿轮泵消除了困油现象,具有压力脉动小、噪声小的特点,适用于对静音性能有较高要求的场合。分析其工作原理,设计了试验工装与试验系统,对多种工况下的压力脉动进行了测试,并对结果进行了时域和频域分析,得到了抑制干扰后的压力波动曲线。结果表明,试验方法具有较高的准确性和统一性;该型泵压力脉动较小,去除干扰后脉动率可达1.5%,具有优良的静音性能。
Double-circular-arc helical gear pumps eliminate oil trapped phenomenon,having small pressure pulsation and small noise,and are very important for applications requiring silent performances.The operation principle is analyzed.The pressure pulsation test rigs and a test system are designed to test various operating conditions,with ISO 10767-2 Simplified Method for Pumps referred.The data is analyzed in time domain and frequency domain,and the pressure pulsation curves after suppressing disturbance are obtained.The results show that the testing method is accurate and uniform,and the pressure pulsation of this type of pump is small,with only 1.5%pulsation rate after suppressing disturbances.
