The intelligent hot and wet tensile strength tester is mainly used
to determine the hot and wet tensile strength of the sand, the
normal temperature wet tensile strength and the quality of the raw
materials such as bentonite. It is the main detection method for
judging the sand resistance of the sand. It is equipped with a
microcomputer intelligent control linear stepping motor loading
system, an intelligent temperature control automatic lifting system
and an intelligent measuring system. LCD Chinese display,
high-precision load cell and micro-Chinese printer. It can automate
the process of testing, counting, displaying, storing and printing.
It is a high-precision measuring instrument in modern scientific
research, teaching and production

Special introduction to Intelligent hot and wet tensile strength
First, the working principle of intelligent hot and wet tensile
The hot-humid tensile strength tester is designed to simulate the
moisture migration mechanism of the sand type when heated. The
hot-humid tensile strength is the tensile strength at which the
high-water layer is formed after the sample is heated. The
schematic diagram is shown in Figure 1. During the test, the
prepared sample is placed on the main sample rail together with the
sample cylinder. After automatic heating (320 ° C, about 20-30 s)
at the bottom of the sample, a dry sand layer (about 4 mm) and a
water condensation zone of a certain thickness are formed on the
heated surface of the sample. It then automatically loads the
displayed force process curve, measures its tensile strength,
displays the measurement results, stores and prints the report.
Second, the main technical indicators of intelligent hot and wet
tensile strength tester
1. Measurement range: 0-25000Pa

Third, the main features of the intelligent heat and wet pull
1. The system circuit design is reasonable, the anti-interference
ability is strong, the Chinese menu liquid crystal display, the
data is stable, the analysis result is accurate and reliable.
2. The analysis process dynamically displays various real-time data
and force value curves. Designed with storage, query printing and
3. Compact heating plate automatic lifting system can automatically
measure and display the temperature of the heating plate, and use
the computer technology and automatic temperature compensation
technology to automatically control the heating plate system.
4. Adopt high-precision linear stepping motor and use microcomputer
technology to realize automatic loading and automatic unloading.
The loading speed and length can be accurate to micrometer.
5. High-precision tensile pressure sensor can be used for digital
collection and processing at normal temperature and high
temperature, and the data is stable and reliable.
6. System menu Chinese display and prompt password protection
function, through the password can reset the system's various
functions and parameters.
7. Can automatically store various data. The query print function
has a Chinese table menu, which can be selected for printing, and
automatically calculates and prints average values for two or
more sets of data.
Fourth, the basic structure of intelligent hot wet tensile strength
DP-ZSL intelligent hot and wet pull tester consists of five parts:
automatic lifting and heating plate, linear motor automatic loading
system, sample clamping mechanism, microcomputer automatic
test-control-display system and micro-printer.
