Introduction to Chemical Storage Cabinets
After the device is powered on, the monitor is turned on. The time display starts working Hour key: The hour key is used to adjust the hour number. When the hour key is pressed, the time display starts flashing, indicating that the hour has entered the setting state. Press and hold the hour key, and the display hour setting can be adjusted from zero to twenty-four. Minute key: The minute key is used to adjust the minute number. When the minute key is pressed while the display is flashing, the time display starts flashing, indicating that the minute has entered the set state. Press and hold the minute key, and the display minute setting can be adjusted from zero to fifty-nine Function keys: Function keys can be used for three main settings. 1. It is the setting of the fan on time when an alarm is triggered. (0-59 minutes) 2. Set the running time of the fan to be turned on every day (0-59 minutes).
Specification of chemical storage cabinet
The cabinet is coated with ABS both inside and outside, and then baked at high temperatures to resist corrosion from various chemical substances; The static grounding wire prevents the cabinet from generating static sparks; Cabinet color: red, yellow, blue; Prominent markings for flammable chemicals; Having fire-resistant and explosion-proof certificates, CE certification Rohs Explosion proof equipment should have a product qualification certificate and an explosion-proof qualification certificate issued by the Explosion proof Electrical Product Quality Supervision and Inspection Center. Product accessories, fittings, and spare parts should be complete, and technical documents should be complete; Cables and insulated wires must have a certificate of conformity. Generally, the PLC of explosion-proof positive pressure cabinets is designed with a high-speed counting port, which essentially utilizes the hardware logic of the underlying microcontroller to complete these encoder counts, avoiding the problem of scanning cycles. The PLC of explosion-proof positive pressure cabinets is designed with dedicated high-speed counting instructions, which can be directly called to read the current pulse value when in use
Chemical storage cabinet type
The utilization rate of fume hoods is high in laboratory construction. To choose a suitable and reasonable installation location for fume hoods, it is necessary to select the type, material, shape, etc. of fume hoods according to the experimental content, and ventilation should be considered. When using organic compounds or other special reagents for experiments, it is necessary to fully consider their control of wind speed. Heat source: When using equipment with a heat source, if the heat exceeds 2000 kcal/h, the ventilation required to dissipate the heat should be considered to determine the power of the fan. When conducting experiments with radioactive substances or excessive acid, a dedicated fume hood should be selected, and the inlet air velocity must be set to be greater than 0.5m/s. When conducting experiments with large equipment, it is important to consider the effective internal dimensions and leave necessary space for ventilation.
