The rain spray test chamber is made of high quality stainless steel short hair pattern board, and the working part is made of high quality 304 stainless steel plate. Test box is composed of main body part, transmission mechanism and electrical parts.
1.The rain test box is driven by mechanical transmission to achieve the test purpose. The turntable transmission mechanism drives the worm through the motor to drive the worm wheel to reach the specified speed. Swing lever is an electric drive reducer that drives the rack drive gear to drive the swing rod. Rotary rod drives the reducer through the motor, and the deceleration surface directly drives the rotary rod to operate. The rain test chamber adopts the electromechanical combination method, and designs the test equipment for simulating the natural rain environment according to the national standard and European and Japanese standards.
2.The amount of water sprayed and the water spray pressure can be adjusted by the size of the switch ball valve.
3.Swing tube angle and the swing tube frequency are respectively achieved by changing the position of the connecting rod on the eccentric wheel and by changing the motor speed.
4.The speed of the table of the test piece is reduced by the worm gear reducer and the inverter changes the motor speed. A bushing device is arranged on the rotating shaft of the table, which can be adjusted up and down in the axial direction to meet the needs of different test piece dimensions.
5. The test time is set and displayed by the time accumulator.
