With 40 years of rich experience in the production of petroleum instruments and equipment, specializing in the production of petroleum, petrochemical, highway transportation, geology and other scientific research and production of instruments and equipment.
Key words:
Asphalt instrument, petroleum instrument, cleaning equipment
Classification:
Case description
LYY-10A-3CL asphalt force ductility tester
The instrument conforms to GB/T4508, JTG E20/T0605 T0662, ASTM D113 standard requirements. It is mainly used to determine the elongation of asphalt at different temperatures, and can also be used to determine the elongation of coal tar pitch.
Performance characteristics:
The use of industrial control computer integrated machine control, touch operation, automatic control of the experimental process.
The sink is provided with an interlayer, which circulates along the sink wall to ensure the accuracy of temperature control. Achieve internal and external double circulation.
The refrigeration system is made separately from the inside of the frame, and the thermostatic water tank is made separately from the water tank. There is no vibration during work. Double circulation pump is used for water reflux to make the water temperature in the water tank more uniform. The refrigeration system adopts imported compressor, which has fast refrigeration and reliable performance.
The sink is made of stainless steel, the screw rod is external, and the linear slide rail is used for positioning, without jitter and smooth transmission.
The stretching speed is stepless speed regulation with imported frequency conversion speed regulator. At the same time, the stretching length is displayed on the industrial control screen respectively, which can be observed clearly and can be locked remotely.
Equipped with 3 sets of belt force measuring device, can carry out three force measuring parallel experiments.
LED lights in the test water tank shall be illuminated to clearly observe the test process.
With USB network cable interface, data transmission can be realized.
With a micro printer, experimental data a key print.
With network cable interface, data transmission.
Main technical parameters:
