Application

This rain test equipment is a non-standard equipment. The artificial simulated rain test box is used for the external lighting and signal devices and the protection of automotive lamp housings. It is an indispensable testing equipment in aerospace, automobile and motorcycle, electrical and electronics, home appliances, scientific research and other fields.

Working Principle

1.Water spray working principle:

The water pump draws water from the water tank in the test box. The water tank → pump → ball valve → filter → pressure regulating valve → flow meter → swing tube (water pressure gauge) in the box → nozzle → test sample → water tank

2.Swing tube transmission works:

Transmission motor → reducer → turntable → connecting rod → rack → gear → connecting shaft → swing tube. The angle of the swing tube can be adjusted by the turntable on the reducer.

Electrical control

1. The sample turntable is controlled by a digital speed regulator (also controlled by a frequency converter, otherwise agreed), and the speed of the turntable is adjusted by directly rotating the speed regulation button.

2. The swing tube is controlled by the controller, and any parameter within the range can be freely set. In addition, the continuous work and gap work of the swing tube can be freely switched, and the time of gap work and continuous work can be set.

3. You can set the total test time according to your needs. This equipment also has time accumulation function. (That is, after each time the device is powered on, the time totalizer continues to last time when the device is powered on, and the totalizer can be cleared)

Note: The above time control is controlled by the respective time relay. The maximum setting time is 99 hours. The unit of time is hour, minute and second. (Except the time relay of the total time, the maximum value of the time relay of the total time is 999 hours, and the unit of time is hour).
