ZM7311 Sprinkler testing rig teaching aid equipment Hydrodynamics Experiment Apparatus
- Product overview
1.1 Product introduction
Moist, loose and fragile soil is best for plant growth. For example, if a fairly dry, baseball-sized block of soil drops from waist height, a well-structured soil will decompose well into debris. The degraded soil is still large and difficult to decompose. Using the sprinkler on the sprinkler to spray a soil sieve containing soil debris is equivalent to applying a strong simulated drop of water on the debris.
The sprinkler device consists of a simple rainfall simulator, equipped with a receiving pan, four funnels, and four soil screens, and uses simulated rainfall within a predetermined rate range. This instrument allows the determination of several important soil hydrological properties: adsorption and field saturation, and permeability.
The transparent material of the simulator makes it easy to observe the water level.
There are 136 elbows installed at the bottom to slow down the water flow and simulate the dripping state.
Sieves with different apertures are convenient for observing the soil that discharges different particles.
1.3 Performance parameters
Elbow drip aperture: 1.5mm
1.4 Completable training projects
Soil dissolution and screening test
1.5 Matters needing attention (operating conditions)
(1) Before the experiment, check whether there is any blockage or debris in the simulated dripping pipe, and perform the experiment after cleaning.
(2) Before the experiment, fill the simulator with cold water so that the water level cannot easily exceed 2/3.
(3) During the experiment, the height of the liquid level should be observed more, and in a period of time, the height of the liquid level should be recorded.
