How to adjust the spray volume of the salt spray test chamber?

Salt spray test chamber is mainly simulated marine climate to detect the degree of corrosion of samples of a test equipment, TEMCO environmental instruments salt spray test chamber spray method mainly uses continuous or intermittent alternating tower spray, it is composed of spray tower, nozzle and air pipe, the height of the tower tip can be freely adjusted, oriented salt mist mist particles fine, natural settlement, the amount of spray adjustable.

intake pressure regulation

Turn on the air pump, connect the air pipe, and open the intake valve on the device. At this time, the intake pressure should be displayed on the intake pressure gauge. The intake pressure can be adjusted by opening the pressure regulating valve on the oil-water separator. There is a pressure regulating valve on the upper part of the oil-water separator. Lift the round valve hand up and then rotate it left and right to adjust the intake pressure. After adjustment, the valve hand needs to be reset. The intake pressure adjustment needs to be determined according to the type of salt spray chamber and salt spray test.

Spray pressure adjustment

Generally, when leaving the factory, the salt spray pressure has been adjusted, and there is no need to adjust it again. If there is a problem with the spray pressure, please call the manufacturer for after-sales service.

The finer the salt spray particles, the larger the surface area formed, the more oxygen is absorbed, and the stronger the corrosion. More than 90% of the salt spray particles in nature have a diameter of less than 1 micron. Research results show that the amount of oxygen adsorbed on the surface of salt spray particles with a diameter of 1 micron is relatively balanced with the amount of dissolved oxygen inside the particles. No matter how small the salt spray particles are, the amount of oxygen absorbed will not increase.

Under normal circumstances, the spray volume does not need to be adjusted. Of course, it can be manually adjusted according to different test products or special requirements. How to adjust the spray volume of the salt spray tester?

1. Adjust the distance between the conical cover on the spray tower and the tower body. If the distance is upward, the spray volume will increase, and if the distance is downward, the spray volume will decrease.

2. It is also possible that there are foreign objects in the nozzle, which affects the spray volume. It can be cleaned, and if the blockage is serious, it is recommended to replace it. To choose better sodium chloride, don't choose the kind that is easy to crystallize.
