油泵误差验证方法

This standard is primarily concerned with "normal test status" under Basic: head, flow, torque and rotational speed (or axle) measurements."Normal test status" refers to a test procedure, these clearly remain constant in order to reduce the uncertainty of intentionally changing circuit resistance or speed. In order to obtain the characteristic curve of the pump, according to the results by a number of different experimental conditions were making head, shaft power and efficiency with the flow curve. For each test condition, the error is subject to change. But need to take repeated readings are only the error limit is annoy me those points that are important or when a reading appears to be trend is not the same as reading obtained under other conditions.Test method for normal pump above. Such conditions of each test in the case of several areas of uncertainty calculation.
本标准主要是根据基本的"正常测试状态"： 头、 流量、 扭矩和旋转速度 （或轴） 的测量."正常测试状态"是指一套测试程序，这些显然保持不变，减少故意更改电路电阻或速度的不确定性。为了获得泵，结果显示，由若干不同的实验条件的特性曲线正在头、 轴功率和效率与流量曲线。对于每个测试条件，该错误会有变化。但需要采取重复的读数是唯一的错误限制是烦扰我那些点重要或当读似乎是的趋势并不相同，读其他条件下取得的。上述的正常泵的试验方法。这种条件的每个测试的不确定度计算的几个地区。
