LX-010 Rain Test Chamber Full Component Testing

Natural rainwater damages products and materials, causing incalculable economic losses every year. The damage caused mainly includes corrosion, fading, deformation, strength reduction, swelling, mold, etc. In particular, electrical products can easily cause fires due to short circuits caused by rain. Therefore, conducting shell protection water testing for specific products or materials is an essential and critical procedure.
Box-type rain test equipment is standard equipment and needs to be installed in a special laboratory to conduct artificial simulated rain tests on products. The water inlet and waterproof facilities in the laboratory must be installed in place. The equipment can be used to assess and determine whether the shells and seals of electrical, electronic products, various electrical appliances and various lighting fixtures can ensure good working performance of the equipment and components after the water test or during the test. The equipment can completely simulate the external rain environment and fully reproduce the impact of the external rain environment on the product.
The artificial simulated rain test of the equipment does not include rainfall with strong wind speed, and does not take into account the large amount of water inflow caused by the temperature difference between the temperature of the test sample and the temperature of the rainwater.
The equipment can provide corresponding environmental simulation and accelerated testing for scientific research, product development and quality control.
2. Equipment usage and overall requirements
The rain test chamber mainly provides a water mist test environment, meets the test standards for protection levels, and is used for reliability identification of samples such as electrical, electronics and lighting fixtures. The equipment meets B standard and test requirements specified in B. standard.

4. Test chamber structure
& Selection of this set of box-type rain test equipment Made of high quality stainless steel material. The equipment consists of a box body, a swing tube bracket, a swing tube transmission mechanism, a working rotating table, and an electrical control part. The box body and control box body are made of stainless steel hairline board. The inside of the swing tube column is welded with channel steel to ensure that the equipment does not shake when the swing tube swings. The rotating table sample holder, flange, connector and other accessories are all made of stainless steel.
&The equipment is designed to install a set of oscillating tubes with a diameter of mm. The oscillating tubes are bent from stainless steel pipes and can swing back and forth. At the same time, water controlled at a certain flow rate and pressure is sprayed through the nozzles on the oscillating tubes. For the test Samples are subjected to water testing. The transmission device for swing tube swing is reasonably designed, precisely manufactured and easy to maintain. The swing of the pendulum tube is completed by an advanced stepper motor, and the rotation frequency and angle as well as the rotation speed of the turntable are automatically controlled by a programmable liquid crystal controller, making the operation simple. The sample rack turntable adopts a liftable device and rotates horizontally. The entire equipment is reasonably designed and durable. On the premise that the equipment complies with national standards and has stable performance in all aspects, it is more practical and easy to control.
&The equipment is equipped with a set of water storage equipment to supply the swing pipe and coil water spray required for the test. The water suction motor presses the water in the water tank into the pipe, and by adjusting the pressure relief water valve, the specified flow and pressure are maintained from the nozzle of the swing pipe. If the test water can be partially recycled, the water sprayed from the nozzle can be returned to the water storage tank for reuse after being filtered. If the test water cannot be recycled, the laboratory must consider drainage so that the test water can be discharged quickly without water accumulation.
5. Control system
& This box-type rain shower equipment uses a programmable liquid crystal controller to control the swing angle, swing frequency, rotation speed of the turntable, and time cycle setting, effectively ensuring that the test is carried out according to the The standard operation control system is equipped with Schneider executive components
& Independent control systems for the swing tube and turntable
& Time settings control several independent systems respectively
&Imported executive components
&No fuse protection switch
&Overload, leakage, fully sheathed terminal blocks, with automatic shutdown and other protections
