Maintenance and precautions of asphalt low temperature extensometer

Release time: August 27, 2020 popularity: eight hundred and sixty

   Asphalt low temperature extensometer The refrigeration system adopts imported components and has a circulation system. The whole process of the test is prompted by Chinese voice. Automatically record the start time and test time of the test. It can store 30 groups of specimen data and query at any time. It can be used to determine the elongation of asphalt and the elastic recovery test of modified asphalt. The temperature is stable. The bath is equipped with internal lighting, white bottom plate and transparent tank cover. The drawing system adopts ball screw and linear guide rail, and the drawing is stable. The drawing speed is adjusted by imported variable frequency stepless speed regulation, automatic high speed homing, with brake system. 5.7-inch LCD touch screen, keyboard input, remote control input, touch input and other input methods to realize man-machine dialogue. Dual core design makes the control more accurate. The elongation is automatically displayed on the screen, and the wireless remote control is locked to calculate the average value. Real time clock, program-controlled Chinese voice time.

 Asphalt low temperature extensometer

The main features of asphalt low temperature extensometer are as follows

1. The refrigeration system adopts imported components and has a circulation system with stable temperature. The bath is equipped with internal lighting and transparent tank cover. Stainless steel base plate * rusty.

2. The drawing system adopts ball bearing and linear guide system, which is stable. The drawing speed is regulated by the imported frequency converter in stages, with automatic high-speed return and brake system.

4. Automatic display of elongation on the screen, wireless remote control locking, automatic calculation of average value, automatic recording of test start time and end time. 30 groups of specimens can be stored.

Maintenance and precautions of asphalt low temperature extensometer:

1. After each test, the water in the water tank is drained to avoid corrosion of metal materials and affect the accuracy and service life of the instrument.

2. After each test, the asphalt mold must be gently wiped with spinning yarn, coated with butter, and placed in a flat place.

3. Please note: before using the instrument, the instrument box should be well grounded to prevent dry deflection.

4. Before using the instrument, oil should be injected from the oil filling holes at both ends. If the machine has abnormal sound, it should be shut down immediately and the fault should be eliminated before starting up.

 Asphalt low temperature extensometer


Asphalt low temperature extensometer is suitable for the elongation of various types of asphalt and liquid asphalt after distillation residue and asphalt emulsion evaporation residue. It can automatically calculate and display the average ductility of three samples and display the temperature digital display. Liquid crystal display working state, with time display, speed display (adjustable speed), force graphics display and sample extension display, can be connected with the printer to print data. After expansion, the computer tube can be connected.
