Structure
The entire test chamber is welded with high-quality plates, which is corrosion-resistant, anti-aging, easy to clean, and non-toxic. Leakage: This test equipment mainly consists of five parts, namely: test box, constant temperature and humidity system, hydrogen sulfide generating device, stirring device and control system.
The shape of this test box is designed with left and right structures, beautiful appearance, reasonable structure, smooth and natural lines. The inner tank material of the box is made of high-quality plastic sheets, with a smooth and bright appearance, good temperature resistance and high strength. Various auxiliary accessories and facilities are also made of temperature-resistant and corrosion-resistant materials.
The box cover is made of high-quality transparent sheet material, and the opening angle is approximately the same. It can also be designed according to the customer's special circumstances. The condition of the specimen indoors can be clearly observed from the outside without affecting the test results. The box cover is designed with an optimal top angle so that condensation water generated during the test will not drip onto the sample and affect the test results. The lid and body of the box are water-sealed to prevent toxic and corrosive gases from escaping, which could affect test results and corrode other equipment in the room, as well as cause possible harm to test operators.
The concentration of hydrogen sulfide gas is controlled by the cylinder drip method. After the gas is decompressed through the relevant gas pressure reducing valve, it is introduced into the test chamber through the air pipe.
The heating design of the box is electric heating of the inner water tank. The volume of the test box occupied by water is approximately /. to ensure the humidity requirements inside the test box during the test. This device is economical and environmentally friendly, heats up quickly, and distributes temperature and humidity evenly. The sample rack is designed in accordance with national standards to have an upper and lower layer with an inclination of degrees and 3 degrees, and can also be hooked.
Function introduction
Hydrogen sulfide environment test
When doing this test, the operator must be careful to open the valve of the hydrogen sulfide cylinder. It is necessary to use a gas mask and anti-corrosion gloves during operation to avoid Hydrogen sulfide spillage causes harm to the human body!
During the test, after the hydrogen sulfide gas is decompressed, it is introduced into the test box through the air pipe. The distance between the pipe and the bottom of the box is used to control the concentration of the gas in the box through a qualified anti-corrosion flow meter and a time controller. The hydrogen sulfide gas waste treatment device generated after the test is located on the rear wall of the box. This equipment is equipped with a set of pressure reducing valves and a paraffin barrel (hydrogen sulfide gas and cylinders are prepared by the customer).
Constant temperature and humidity environment (invasive environment)
During this function, the test chamber stops supplying gas, and the water at the bottom is evaporated through electric heating, generating moist heat, which is stirred evenly by a corrosion-resistant breeze motor and introduced into the chamber. The relative humidity of the box can be controlled within a range, and the heater of the steam generator maintains the set temperature and humidity. It is intelligently controlled by the temperature controller and automatically calculated to achieve the required moist and hot effect. At the same time, turn on the stirring fan inside the test box to keep the gas and temperature and humidity in the box uniform.
Control system
The above environmental functions can be automatically realized through the control system.
The temperature and humidity controller adopts Korean true color LCD touch screen programmable controller, which can automatically operate according to the set curve. It has an R3 interface and can be connected to realize test data recording, test data and curve recording and output functions. /English human-machine interface (connected to the control computer to achieve real-time monitoring and control, the control computer has a network card and B interface) (optional)
