Product Description
The damage caused by natural rainwater to products and materials causes an inestimable economic impact every year loss. The damage caused mainly includes corrosion, fading, deformation, strength reduction, swelling, mold, etc. Electrical products in particular are prone to 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.
This set of waterproof testing equipment can be used to assess and determine whether the shells and seals of electrical and electronic products can ensure good working performance of the equipment and components after or during the water test. The equipment can completely simulate the external rain environment and fully reproduce the impact of the external rain environment on the product.
This equipment can provide corresponding environmental simulation and accelerated testing for scientific research, product development and quality control.
Reference standard
Made according to standard B - enclosure protection level, and the requirements for equipment in B. It can carry out swing tube rain test with swing amplitude of &r;~&;&r; (theoretical value). The artificial simulated rain test of this 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.

Structural design and configuration
The rain test equipment consists of a box/swing tube and a transmission/working rotary table/electrical control part.
.This set of rain test equipment is made of high-quality stainless steel materials. The equipment consists of a box body, a swing tube, a swing tube transmission mechanism, a working rotating table, and an electrical control part. The swing tube brackets, boxes, etc. are all made of stainless steel hairline plates. The swing tube does not shake when swinging. The equipment's rotating table sample holder, flange, connector and other accessories are all made of stainless steel, and the rotating table surface is made of hard plate or aluminum plate.
.This equipment is designed to install a set of swing tubes with a radius of mm. The nozzle is a detachable special nozzle. The nozzle hole can be replaced and the direction of the water spray can be adjusted. The water droplets ejected have a uniform flow rate; the transmission device of the swing tube is reasonably designed and made with precision. The swing angle and frequency are driven by an advanced stepper motor accelerator and reducer. The swing angle and frequency can be directly adjusted on the The instrument setting is controlled by the controller and the operation is simple, avoiding the inaccuracy and cumbersome manual adjustment by feeling of similar equipment in the past.
.The swing tube and bracket are connected by flange, which is very convenient to install and disassemble. The swing tube is made of an industrial stainless steel pipe with an inner diameter of 2. It can swing back and forth while spraying water controlled at a certain flow rate and pressure through the nozzle on the swing tube to conduct water tests on the test samples.
. The swing of the swing tube is completed by an advanced stepper motor. The rotation frequency and angle and the rotation speed of the turntable are automatically controlled by a programmable liquid crystal controller. After setting the swing speed and angle of the swing tube, press the set value to turn it on. Operation is simple. The sample rack turntable rotates horizontally. The entire equipment is reasonably designed and durable. On the premise that the equipment meets national standards and has stable performance in all aspects, it is more practical and easy to control, avoiding the inaccuracy and cumbersome manual adjustment of similar equipment in the past.
.The equipment is equipped with a set of water storage tanks of considerable capacity to supply the swing pipe water spray required for the test, which is resistant to pressure and corrosion. The water tank is covered to prevent dust and debris from entering. Equipped with water quality filter, water inlet float valve and drain valve.
.Rotary workbench: The top of the rotary workbench is made of hard plate to facilitate the installation of test specimens. The turntable is equipped with test specimen fixing bolts. The reducer is used to drive and adjust the speed to the rated speed.
.Electric control cabinet: Above it is the control panel control screen, and the button switches are placed here for easy operation and the working status is clear at a glance. Below is the high-power distribution cabinet where various executive components are installed. Reasonable arrangement, clear direction and easy maintenance. AC contactors and relays are all French Schneider brand-grade products. Other components such as push button switches are from well-known brands.
.Observation window: In order to facilitate the observation of test conditions, the chamber door adopts a tempered glass door to observe the test status at any time.
.Waterway filter: All sprayed water must be filtered before returning to the water storage tank to prevent impurities from entering the water storage tank. All test water uses local clean tap water sources. Before the water in the water storage tank enters the drip tray, a filtering device is added to ensure that the drip holes are not easily blocked.
.Water pump: A stainless steel multi-stage centrifugal pump is used to meet the test water needs and pressure requirements.
.Flowmeter: The glass rotor flowmeter can be used to control the flow of water in real time.
.Pressure gauge: The current water source pressure is displayed by a pressure gauge that displays the actual pressure.
