China's pendulum pipe rain test equipment is leading the way in the country

The damage of natural rainwater to products and materials causes incalculable economic losses every year. 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. Waterproof testing equipment can be used to assess and determine whether electrical and electronic product casings and seals can ensure good working performance of 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.
The equipment can provide corresponding environmental simulation and accelerated testing for scientific research, product development and quality control.
Reference standards
This product meets the requirements of the "Basic Environmental Testing Procedures for Electrical and Electronic Products: Water Test Methods" in strict accordance with the corresponding national standards and other relevant standards such as the protection level, , etc. of low-voltage electrical appliances. Design and manufacture of technical parameters. Water tests specified in corresponding standards can be carried out.
Introduction to structural design
The swing tube rain test equipment is made of high-quality materials and processed using the most advanced CNC processing equipment in the country. The equipment consists of four parts: swing tube bracket, swing tube transmission, working rotating table, and electrical control. The bracket, turntable protective cover and console are made of stainless steel hairline plates. The inside of the oscillating tube column is welded with channel steel to ensure that it does not shake when the oscillating tube swings. The edging material of the column is made of stainless steel plates to prevent it from rusting during water tests. The sample holder, flange, connector and other accessories of the equipment All are made of stainless steel.
The swing pipe of the equipment is made of bent stainless steel pipe and can swing back and forth. At the same time, water controlled at a certain flow rate and pressure is sprayed through the nozzle on the swing pipe to conduct water tests on the test samples. The transmission device of the swing tube is reasonably designed, precisely manufactured and easy to maintain. The rotation frequency is automatically controlled by the frequency converter and the angle can be adjusted easily. The sample rack turntable adopts a manual lifting device designed to carry a kilogram load and can rotate horizontally. The rotation speed is automatically controlled by a frequency converter and can be adjusted. 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 needs to be equipped with a water storage tank to supply the swing pipe water spray required for the test. The water suction motor presses the water in the pool into the pipe and sprays it out from the nozzle of the swing pipe by adjusting the pressure relief water valve to maintain the specified flow and pressure. The water used in the test is recycled. When the open swing pipe is exposed to rain, drainage must be considered so that the test water can be discharged quickly without accumulation of water.

Laboratory facility layout
The laboratory should have sufficient The space with lighting, power supply, water supply and drainage facilities to accommodate the entire set of equipment is complete.
The laboratory floor should be paved with non-slip and anti-seepage materials. A wide and deep drainage ditch should be left around the floor to facilitate the discharge of waste water during the test. The waste water can be smoothly discharged outside through the drainage ditch to ensure that there will be no accumulation on the laboratory floor. Water production affects the test.
The laboratory should be equipped with a water storage tank that is sufficient for test water. The location of the water storage tank should be reasonably arranged to ensure the convenience of water inlet and outlet and test water, and to ensure that it does not affect the test. The water storage tank can be designed with a height, width and depth using masonry structure and ceramic tile veneers inside and outside to ensure that water does not seep in and water can be easily discharged.
The walls of the laboratory should be made of impermeable ceramic tiles with a veneer height of at least 100 meters. A waterproof and leakage-proof power supply device should be installed at a suitable location on the wall. The power supply used by the equipment is three-phase and five-wire.
The space occupied is depth, width and height.
