Description

Technical Field

[0001] This utility model relates to the field of test chamber technology, specifically a composite salt spray damp heat test chamber. Background Technology

[0002] A composite salt spray and humidity test chamber is a device used to test the corrosion resistance of materials or products. It combines the simulation of salt spray and humid heat environments to test the durability and reliability of materials under extreme conditions. By controlling temperature, humidity, and salt spray concentration, the chamber simulates harsh conditions in real-world use, helping manufacturers evaluate and improve the corrosion resistance of their products and ensure their long-term stability and safety.

[0003] A novel salt spray damp heat test chamber, disclosed in CN216449402U, includes a chamber body. A water tank is fixedly installed on one side of the top of the chamber body. A water pump is fixedly installed on the top of the water tank. A water pump is fixedly connected to the pump's suction end and a water pipe, one end of which extends through the water tank into its interior. An outlet pipe is fixedly connected to the pump's outlet end. An atomizing nozzle is fixedly installed on the inner top wall of the chamber body, and one end of the outlet pipe is connected to the inlet of the atomizing nozzle. This invention utilizes a filter box, filter plate, and water pump to circulate the filtered salt water back into the water tank, enabling salt water recycling and reducing loss and waste. A platform attached to the top of a crossbar facilitates easy removal and cleaning. A sieve box collects rust particles washed off the surface of the experimental materials, facilitating the measurement of corrosion.

[0004] Existing composite salt spray damp heat test chambers mostly spray salt water directly onto the workpiece when testing the corrosion resistance of materials or products. This does not result in the salt water being sprayed evenly onto the workpiece, leading to poor corrosion resistance test results. Therefore, we propose a composite salt spray damp heat test chamber. Utility Model Content

[0005] The purpose of this invention is to provide a composite salt spray damp heat test chamber to solve the problem mentioned in the background art that the salt water cannot be sprayed evenly onto the workpiece, resulting in poor corrosion resistance test results.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] A composite salt spray damp heat test chamber includes a test chamber body. The inner cavity top wall of the test chamber body is equipped with a heating device and a humidification device. A sealing door is movably connected to the front end face of the test chamber body, and a transparent porthole is provided on the sealing door. A salt water tank is provided on the top of the test chamber body. An infusion tray is installed on the right inner wall of the test chamber body, and the infusion tray is connected to the salt water tank through a liquid supply unit. Multiple sets of interconnected atomizing nozzles are connected to the outer wall of the infusion tray.

[0008] An L-shaped plate is installed on the left outer wall of the test chamber. A servo motor is connected to the inner wall of the L-shaped plate, and the output end of the servo motor is connected to a drive gear. The inner side of the drive gear is rotatably connected to the left outer wall of the test chamber through a bearing. A driven gear is meshed with the side wall of the drive gear, and a rotating shaft is installed in the middle of the inner side of the driven gear. The rotating shaft passes through the left side wall of the test chamber, and a clamping component is provided at the bottom of the rotating shaft. A collection box is provided on the bottom wall of the inner cavity of the test chamber.

[0009] Furthermore: the clamping component includes a U-shaped frame, a handwheel on the U-shaped frame, and a double-acting screw connected to the bottom end of the handwheel. The bottom end of the double-acting screw is rotatably connected to the inner wall of the U-shaped frame through a bearing. Two sets of threaded blocks are threadedly connected to the double-acting screw. A vertical rod is provided on the inner wall of the U-shaped frame and inside the double-acting screw. Two sets of sliders are slidably connected to the vertical rod. The outer wall of the slider is connected to the threaded block, and a clamping plate is installed on the outer wall of the threaded block.

[0010] Furthermore: the liquid supply unit includes a delivery pump, which is located on the top wall of the test chamber. The inlet of the delivery pump is connected to a connecting pipe, the bottom end of which is connected to the inner cavity of the saline tank. The outlet of the delivery pump is equipped with a delivery pipe, the bottom end of which is connected to the delivery tray.

[0011] Furthermore: the brine tank is equipped with a connecting liquid inlet pipe, and the liquid inlet pipe is threaded with a cap.

[0012] Furthermore, anti-slip pads are installed on the inner sides of both sets of clamping plates.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] This invention utilizes the rotation of the handwheel on the clamping component to drive the rotation of the bidirectional lead screw. Two sets of threaded blocks, threaded to the bidirectional lead screw, are limited by the sliding of the vertical rod and the slider, allowing adjustment of the distance between adjacent clamping plates. This enables the fixing of workpieces of different sizes. The servo motor drives the rotation of the drive gear. Since the drive gear meshes with the driven gear, it in turn drives the clamping component at the bottom of the rotating shaft on the inner side of the driven gear to rotate, thus causing the workpiece clamped on the clamping component to rotate. The delivery pump transports the brine from the brine tank to the delivery tray and multiple atomizing nozzles, allowing the brine to be evenly sprayed onto the workpiece, improving the testing results.
