Drug refill bottle

PP polypropylene board, hidden attached water level gauge, the brine required for the test is prepared and filled from the reagent inlet, and the solution is transported to the internal brine tank of the laboratory through a pipeline without opening the cover

Humidification water replenishment tank

PP polypropylene board, external humidification water tank, hidden attached water level gauge, water inlet Installing a water purifier can effectively filter impurities in the water

Saturated barrel

PP pipe is used, which has the best insulation effect and corrosion resistance. The compressed air passes through the air saturation generator, and the air and distilled water are fully exchanged and filtered to make the air reach a saturated steam state, and moist and clean compressed air is obtained. By adjusting the temperature of the air saturation generator, the temperature balance is ensured, with manual and automatic water replenishment functions

Harmonizing room

The inner and outer boxes use titanium metal blending chambers, which are anti-corrosive, heat-resistant and have a long service life

Harmonizing chamber insulation material

Polyurethane hard foam insulation layer

Base

Channel steel painted with plastic PP package and movable casters

Air duct

The specially designed sealed damper device can automatically switch to salt spray or temperature and humidity test

Sample racks

1. The dividing frame is placed on the inner wall of the PVC polyethylene triangular groove box, and the angle of the test product can be adjusted arbitrarily. The fogging and fogging are completely consistent on all four sides, and a large number of test pieces can be placed.

2. A PVC plate punching sample placement platform is set at the bottom of the test box. The uniform openings on the surface of the platform quickly discharge the spray liquid, and large samples can be placed on the table for testing.

Air circulation system

Built-in air room and stainless steel circulation fan, through the damper and diffuser, the wind is blown out of the evenly distributed air duct, distributing the adjusted temperature and humidity in the adjustment room to the test space, thus achieving the purpose of evenly controlling the temperature and humidity

Control panel

Air supply

Air compression: optional

Spray pressure regulation: The spray pressure is 0.07-0.17Mpa, which can be adjusted in two stages. The first stage is to adjust the compressed air to 0.2-0.3MPa; the second stage is to adjust the spray pressure to 0.07-0.17Mpa so that the spray pressure sprayed from the nozzle is within the specified range.

Spray control

Manual spraying or automatic spraying can be performed according to the program

Demisting method

Compressed air is used to fill the room and then discharge the indoor fog to quickly defog

Circulation working method

The working mode adopts dry and wet, salt spray separate control mode. When the machine is conducting salt spray test, the dry and wet control box will automatically close. When dry and wet experiments are required, the damper is switched to the dry and wet control box, and the salt spray test is automatically stopped at the same time. Intelligent TS time signal control can control periodic spray or continuous spray to achieve automatic operation of dry, wet heat, and salt spray cycles
