Description

Technical Field

[0001] The utility model belongs to the technical field of test equipment, and in particular relates to a wet heat test box that can be used for circumferential immersion tests. Background Art

[0002] Humidity test chambers are essential testing equipment for fields such as aviation, automotive, home appliances, and scientific research. They are used to test and determine the parameters and performance of electrical, electronic, and other products and materials after undergoing temperature changes such as high temperature, low temperature, humidity, or constant temperature testing. Currently, if organizations that already have humidity test chambers want to conduct metal stress corrosion testing, they must purchase additional immersion test equipment; otherwise, immersion testing will be impossible. When conducting immersion testing, environmental factors such as temperature, humidity, and corrosive medium concentration must be controlled to better simulate the natural atmospheric environment, thereby accurately evaluating atmospheric corrosion and stress corrosion of metals. Utility Model Content

[0003] In response to the current problems, the utility model aims to provide a wet heat test chamber that can be used for cyclic immersion tests. By modifying the wet heat test chamber, cyclic immersion tests can be carried out in the wet heat test chamber, achieving multiple uses of one machine, improving equipment utilization and reducing test costs.

[0004] In order to achieve the above purpose, the technical solution adopted by the utility model is:

[0005] A wet heat test chamber that can be used for circumferential immersion tests includes a chamber body, and its structural features are as follows: a linear guide rail, a motor, an etch tank, and a suspension arm are provided in the chamber body, and the linear guide rail is arranged vertically; one end of the suspension arm is connected to the linear guide rail via a slider, and the other end is provided with a connecting rope, the end of the connecting rope is used to suspend the sample, and a water tank is arranged below the connecting rope; the output end of the motor is connected to the slider, and the slider can move up and down along the linear guide rail under the drive of the motor, so that the sample is immersed in the etch tank or moved upward away from the etch tank.

[0006] When the wet heat test chamber of the present invention is used to conduct a cyclic immersion test, the prepared etching solution is added to the etching tank, the processed stress corrosion specimen is fixed on the connecting rope, and the connecting rope is reserved for a suitable length. The wet heat test chamber is started until the temperature and humidity in the chamber are stabilized at the conditions required for the cyclic immersion test. The motor is started, and the motor drives the slider to move up and down along the linear guide rail, so that the stress corrosion specimen moves downward into the etching solution and is immersed for a period of time. After that, the stress corrosion specimen is driven by the motor to move upward to the air environment and stay for a period of time, and then moves downward to the etching solution and is immersed. This cycle is repeated to conduct the cyclic immersion test. The wet heat test chamber of the present invention, which can be used for cyclic immersion tests, meets the standard requirements of cyclic immersion tests by modifying the wet heat test chamber, and at the same time realizes multiple uses of one machine, which can improve equipment utilization and reduce test costs.

[0007] Preferably, a water supply tank and a water pump are provided outside the housing, and a liquid level probe is provided inside the etching tank; the water supply tank and the etching tank are connected via a water supply pipe, the water pump is connected to the water supply pipe, and the liquid level probe is electrically connected to the water pump. In order to maintain a certain liquid level of the etching solution in the etching tank, the liquid level probe is provided for monitoring. When the liquid level falls below a set value, the water pump is activated to replenish liquid into the etching tank through the water supply pipe.

[0008] Specifically, the water supply pipe and the electrical connection line between the liquid level probe and the water pump are all inserted through the reserved holes on the side wall of the box. Existing damp heat test chambers have reserved holes on the side walls of the box, which can be used to lay the water supply pipe and related electrical lines.

[0009] Specifically, the linear guide rail is fixedly connected to the side wall of the box through a plurality of support beams, and the motor is arranged at the bottom of the linear guide rail.

[0010] Preferably, a controller is provided outside the box, and the motor is electrically connected to the controller. In order to facilitate the immersion test, the motor is controlled by the controller, which is easy to operate.

[0011] Specifically, the electrical connection line between the motor and the controller passes through the box body through the reserved hole on the top of the box body. The existing damp heat test box box body top has a reserved hole, which can be used to lay the relevant electrical lines.

[0012] Preferably, the motor is a stepper motor.

[0013] Compared with the prior art, the beneficial effects of the present invention are as follows: the wet heat test chamber of the present invention, which can be used for cyclic immersion tests, meets the standard requirements of cyclic immersion tests by modifying the wet heat test chamber, while achieving multiple uses of one machine, improving equipment utilization and reducing test costs.
