Abstract
本实用新型公开一种测量高粘流体粘度的装置,该装置主要由高粘度流体完全湍流发生装置、转速和扭矩变频调节器、温度传感器及数据采集系统等组成。高剪切转子由电机直接带动,在高速旋转中产生高剪切力,使剪切室里的高粘度流体实现流体化,达到完全湍流。因为高粘流体的粘度是指流体在受到外力作用时抵抗流体发生变形的阻力,从能量的观点来看,高粘流体的粘度实质上是一种能量的耗散,即流体受到高剪切作用力时,由于摩擦作用而产生热量导致温度升高,并以热的方式被耗散。因此该实用新型通过数据采集系统测得高粘流体在流体剪切室内达到完全湍流后的能量耗散值,结合其它流体动力学参数则可得出高粘流体的有效粘度值。
The utility model discloses a device for measuring the viscosity of a high-viscosity fluid, which is mainly composed of a high-viscosity fluid complete turbulence generating device, a speed and torque frequency conversion regulator, a temperature sensor, and a data acquisition system. The high-shear rotor is directly driven by a motor, and generates a high shear force during high-speed rotation, so that the high-viscosity fluid in the shear chamber is fluidized and reaches complete turbulence. Because the viscosity of a high-viscosity fluid refers to the resistance of the fluid to deformation when it is subjected to an external force, from the energy point of view, the viscosity of a high-viscosity fluid is essentially a dissipation of energy, that is, when the fluid is subjected to a high shear force, heat is generated due to friction, resulting in an increase in temperature, and the temperature is dissipated in the form of heat. Therefore, the utility model measures the energy dissipation value of the high-viscosity fluid after it reaches complete turbulence in the fluid shear chamber through a data acquisition system, and the effective viscosity value of the high-viscosity fluid can be obtained by combining other fluid dynamics parameters.
