摘　　要：选择电阻应变片采集单螺杆低温榨油机榨膛内压力。利用材料试验机对电阻应变片进行标定,得出应变片的压力-电流关系。榨油机工作过程中,电阻应变片与高温熔体压力传感器在同一位置测得的每分钟最高压力相同,证明应变片传感器标定准确,可以用于榨膛内压力实时采集。榨油机稳定工作时,榨膛内的最大压力出现在压榨段。通过调整榨油机的压缩比、榨条间隙和出饼间隙,得出不同结构参数对榨膛压力分布的影响,为调整榨膛结构参数以达到最优压榨效果提供了参考。Resistance strain gauges were used to collect the pressure in the barrel of single screw press. The material testing machine was used to calibrate the resistance strain gauge, and the pressure-current relationship of the strain gauge was obtained through the test. During the working process of the press, the maximum pressure per minute measured by the resistance strain gauge and the high-temperature melt pressure sensor at the same position was the same, which proved that the strain gauge sensor was accurately calibrated and could be used for real-time collection of pressure in the barrel. When the press worked stably, the maximum pressure in the barrel appeared in the press section. By adjusting the compression ratio, cage bar gap and cake thickness of the press, the influence of different structural parameters on the pressure distribution in the barrel was obtained. The research provided a reference for adjusting the structural parameters of the barrel to achieve the optimal pressing effect.
