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.
