椭圆齿轮流量计是一种特殊的油马达,是根据其转速来确定流量的。因此是一种体积计量的仪器,与各种速度式流量计相比,油的粘度变化对计量精度影响较小,在一般液压系统中能达到较高的计量精度(出厂标准0.5％),应用较广。我校新建的100KW综合式液压试验台即采用了LC—40流量计为主油路的流量计量,使用效果良好。 LC—40流量计(上海产)为累积式表盘显示,对液压试验既不方便又不准确,影响使用。为此,我们对仪表进行了改装,利用现有设备便可达到数字显示目的,如图1所示。在芯轴1上穿一根小轴2,其左端与椭圆齿轮固定,右端装一圆盘3,用以显示椭圆齿轮的转速,
Oval gear flow meter is a special oil motor, is based on its speed to determine the flow. Therefore, it is a kind of volumetric measuring instrument. Compared with various velocity flow meters, the change of viscosity of oil has little effect on the measuring precision. It can achieve higher measuring accuracy (0.5% of the factory standard) in the general hydraulic system. Wider. Our new 100KW integrated hydraulic test rig that uses the LC-40 flow meter as the main oil flow measurement, the use of good results. LC-40 flow meter (Shanghai production) for the cumulative dial display, the hydraulic test is not convenient and not accurate, affecting the use. To this end, we have modified the instrument, the use of existing equipment can achieve the purpose of digital display, as shown in Figure 1. A small shaft 2 is worn on the mandrel 1, the left end of the mandrel 1 is fixed with an oval gear, the right end is provided with a disk 3 for displaying the rotation speed of the oval gear,
