Thermostatic water bath test device for measuring cement density and test method thereof

Abstract

The invention discloses a thermostatic water bath test device for measuring cement density and a test method thereof. The thermostatic water bath test device comprises a thermostatic water bath base and a Lee's bottle, wherein the height of the thermostatic water bath base is greater than the height of the Lee's bottle, the thermostatic water bath base is provided with a fixing support capable ofmaintaining the Lee's bottle in the vertical direction therein, a side wall of the thermostatic water bath base is provided with a transparent observation area, and the transparent observation area isprovided with a reading telescope used for reading the scale of the Lee's bottle. The thermostatic water bath test device of the invention has the beneficial effects of simple structure and easy operation, capacity for effectively avoiding the influence of manual operation and environment temperature, capacity for improving test accuracy, and achieving good practical effect and promotion value.

Description

technical field [0001] The invention relates to the technical field of cement density detection equipment, in particular to a constant temperature water tank test device and a test method for measuring cement density. Background technique [0002] At present, when carrying out cement density experiments in the laboratory, the traditional constant temperature water tank needs to soak the Lee's pycnometer filled with kerosene in the constant temperature water tank, keep it at 20°C ± 1°C for at least 30 minutes, and then take the reading. The volume change is relatively sensitive. The traditional constant temperature water tank is greatly affected by human operation and ambient temperature during the cement density test, the test accuracy is not high, and the operating level of the test personnel is relatively strict. The application number is 201720698844.7, and the patent name is "A Test Device for Measuring Cement Density", which discloses a test device for measuring cement ...

AI Technical Summary

Problems solved by technology

The disadvantages of this patent are as follows: 1. The Lee's bottle cannot be guaranteed to be placed vertically in the constant temperature water tank, resulting in defects in the reading of the Lee's bottle; 2. The Lee's bottle is not immersed in the constant temperature water tank as a whole, causing the temperature to have an impact on the test accuracy; 3. The liquid level sensor has an influence on the height of the liquid level in the Lee's bottle, and the higher the liquid level, the greater the immersion volume of the liquid level sensor, and the greater the impact, resulting in an incorrect reading of the liquid level in the Lee's bottle
