Housing construction of neutral salt spray test chamber

1.
Sprayer equipment: vertical sprayer, hidden laminated glass nozzle, sprayer is correctly guided by the tower tube and then dispersed by cone, uniform dispersion and diffuse to all laboratories; 2.
Adjustment of the size of the sprayer: increase the amount of the conical disperser on the spray tower to increase, and reduce the amount of the sprayer less; 3.
Dust collector: the fine mist sprayed by the nozzle is settled by the free fall method, and one or more tube cups with an area of 80cm2 are embedded to collect corrosion resistance, solidify into water and flow from the hose to the measurement verification cylinder outside the shell; 4.
Heated stainless steel sink: The stainless steel sink is attached to the bottom of the laboratory to hold water and heat up to maintain the stability of the laboratory temperature; 5.
Storage shelf: made of plastic steel profile, single load does not exceed 2kg, such as decentralized placement can bear the net weight within 10kg, there are two rows of round holes on both sides of the storage shelf, is placed in the vertical surface of 15 degrees, 30 angles
。 External structure 1, environmental test chamber cover: house-shaped diamond-shaped 110-degree see-through cover, which can clearly observe the experimental situation in the room; 2.
Block stainless steel sink: use water to seal the box cover to prevent corrosion resistance and leakage; 3.
Measurement verification cylinder: collect the amount of sprayer for each experiment, and 50ml each time is the ruler; 4.
Saturated state gas barrel: placed at the bottom end of the control cabinet, made of SUS#304 stainless steel plate, which has the effect of over-consideration, heating and humidifier, so that the purified indoor air exceeds the saturated state temperature and ambient humidity to the nozzle sprayer, and the saturator has a fully automatic hydration and moisturizing effect; 5.
Pressure reducing valve: manually adjust the working pressure of the air inlet and the working pressure
of the sprayer.
The working pressure of the air inlet is operated at 0.
3mPa; the working pressure of the sprayer is operated at 0.
07-0.
17mPa
.
(The working pressure has been adjusted before the original factory, and the customer does not need to adjust it under normal circumstances); 6.
Air pressure gauge: The working pressure displayed by the needle of the air pressure gauge is the working pressure when the gas barrel is transferred to the nozzle sprayer in the saturated state; 7.
Replenishment water tank: fully automatic or manual filling of tap water in saturated state barrels; 8.
Fogging pipe: PVC hard plastic hose with a diameter of 50, the working pressure caused by the sprayer is spilled out during the work of the salt spray test chamber, and the unnecessary water on the body of the box is also overflowed
.
Neutral salt spray test chamber materials for machinery and equipment materials usually use PVC
and PP.
PVC is used
as a neutral salt spray test (NSS test) and salt spray test (SS test).
PP board
is used for acetate fog test (ASS test) and copper accelerated vinegar instinctive reaction test (CASS test).
PP board is more resistant to heat and high strength erosion than PVC board
