PRODUCTS DETAILS

The rain test chamber is designed and manufactured in accordance with relevant national standards, and is widely used in aerospace, aerospace, military, naval, electrical, electronic and other industries to simulate dynamic operation of the whole machine and parts of the product in a rainy environment to evaluate the product Work quality test. In order to evaluate the performance and quality of the sample.

The structure design of the test system is advanced and reasonable, the manufacturing process is standardized, the appearance is beautiful and generous, and the maintenance is convenient. The matching of parts and components is well matched. The main functional components are all imported parts with international advanced level, which improves the safety and reliability of the product and can ensure the long-term and high-frequency use requirements of users. The ancillary conditions required for the normal operation of the equipment are already equipped, and the buyer only needs to provide the power and the working environment that meets the requirements.

The structure and working principle of the rain shower device

Working principleThis equipment uses a high-pressure water pump to sprinkle a certain pressure and a certain flow of test water on the sample through the swing rod nozzle, and rotate the test device to change the swing amplitude and frequency of the swing rod to reach the environment required by the test.

Structure of equipment:

The test box body is an integral structure, the rainwater tank, high-pressure water pump, and the rotating system of the test device are located in the lower part of the box, and the control system is located directly under the test box.

The test box is a single door, sealed with double-layer anti-aging silicone rubber.

There is an observation window on the door of the box.

The equipment is equipped with switch-controlled lighting.

Waterproof rotary joint and frequency conversion system are installed on the right side of the test box.

Equipment material

The outer shell is sprayed with cold-rolled steel plate / the inner wall of the working chamber is formed by SUS304 mirror stainless steel plate.

Special motor, centrifugal convection fan

The temperature measurement adopts imported PT-100 sensor.

Silicone rubber sealing strip, imported waterproof sealing rotary joint

Flow regulating valve and speed regulating motor.

Sample holder and sample holder rotating structure, glass observation window.
