Rain Erosion Test Chamber / Splash Erosion Test Chamber/ water droplet erosion Manufacturers Bangalore India

n the start of runoff. Splash Erosion results in the first stage of erosion process, it results in the bombardment of the soil surface by raindrops, it Is the primary cause of soil detachment and soil disintegration and resettled sediment blocks soil pores resulting in surface crusting and lower infiltration. Rainfall can cause erosion both when the rain hits the surface of the Earth, called splash erosion, and when raindrops accumulate and flow like small streams. Rivers - Rivers can create a significant amount of erosion over time. They break up particles along the river bottom and carry them downstream. The rain erosion test chamber consists mainly of an eight foot diameter, double arm blade designed to produce high tip velocities with zero lift and low drag coefficient. Duplicate test specimens are mounted at the leading edge tip sections of the double rotating arm. The specimens can be rotated at variable velocities between 100 and 650 MPH. The double arm blade is mounted horizontally on a vertical drive shaft (Figure 1). The simulated rainfall is produced by four curved manifold quadrants. Each manifold has 24 equally-spaced capillaries. De-ionized water is delivered to the four manifold quadrants simultaneously from a constant volume water storage tank. Temperature controlled water then fills the capillaries to produce raindrops. Drop size and drop rate are controlled by the water temperature, capillary orifice diameter, and head pressure of the water storage tank. Raindrops from the simulation apparatus impact the test specimens throughout their entire annular path. Drop size and drop rate are approximately 1.8 to 2.2 mm and 6 to 7 drops per second, respectively. At Kelviron technologies we manufacture rain erosion test chambers according to client’s needs. We perform rain erosion tests using a rotating arm that exposes the test objects to the desired amount of water at the desired speed (typically 160 m/s at the blade tip) and for the desired intervals. Depending on the method applied, it is also possible to run tests at different temperatures and using droplets of different sizes. Each test run features three test objects in the form of GFR profiles to which the customer has fitted the LEP solution. Rain is not the only factor that causes erosion of blade leading edges and systems for protecting these edges. In most cases, UV radiation, salt mist, sand and other airborne particles will also contribute to the detrimental effects. These factors can cause leading edge protection solutions to erode earlier and faster than expected. This should therefore also be included in the overall assessment of the performance of the leading edge in connection with a rain erosion test. The Rain Erosion Tester from R&D Test Systems helps improve the longevity of wind turbine blades by testing erosion on the leading edges of the blades. It is based on a 3-bladed helicopter principle with test specimens shaped like the leading edges of a standard wind turbine blade. This test setup ensures conditions very similar to real-life harsh weather in an accelerated way.
