Core high speed refrigerating centrifuge Core sample capillary pressure testing centrifuge

Core high speed refrigerating centrifuge, used to determine capillary pressure and wettability of core samples and related core properties.

Soil pF curve detection is determined by the relationship among soil suction, bulk density and weight water content, so as to obtain high-precision soil moisture characteristic curve pF.

Soil water characteristic curve is usually measured by pressure membrane (chamber) and centrifuge. Compared with other methods, centrifuge method is simple and time-saving, and can measure a wide range of suction. It is widely used in soil moisture dynamic simulation, meteorology, climatology, soil geography, hydrology, 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.
