Floor Type Soil PF Curve Frozen Centrifuge HR21M Detecting
Centrifuge | Minerals In Centrifuge | Soil Analysis
At present, a domestic soil pF curve detection centrifuge is
determined by the relationship between soil suction, capacity and
weight and water content, so as to obtain a high-precision soil
water characteristic curve pF.
Soil moisture characteristic curve are usually determined by
pressure membrane (chamber) and centrifuge.The centrifugation
method is simple and time-saving than other methods, and can
determine a wide suction range. It is widely used in the field of
soil water dynamic simulation, meteorology and climatology, soil
geography, hydrology, and agricultural science and technology.
Characteristics of centrifuge were detected by soil pF curve:
1. Large torque AC frequency conversion motor, without toner
pollution and extended service life.
2. Frequency frequency drive system and intelligent control system
to ensure stable and reliable work.
3. The refrigeration system adopts the French Taikang compressor
set, with arbitrary temperature adjustable, high temperature
control accuracy and small noise.
4. Ultra-temperature, overspeed, electronic door lock, imbalance
and other protection.
5. Soil with pF curve high-speed frozen centrifuge HR21M, the
fuselage is full metal structure, stainless steel internal cavity,
strong and durable.
6. Intelligent interface, TFT real color 4.3-inch screen, touch
button dual control system, microcomputer control, synchronous
display of set parameters and operation parameters.
7. Users can set 16 running programs and modify the control
parameters of the running rotor at any time.
8. Programmable operation, 10 gear lift time for the user to set
arbitrarily.
9. Soil centrifuge can show the speed rise, drop curve, centrifugal
integral curve and temperature curve.
