Uses and Working Conditions 1.1 Applications BLZ51 series explosion-proof operation columns (hereinafter referred to as operation columns) are applicable to Zones 1 and 2 of Class IIA, IIB, or IIC, Group T6 explosive gas atmospheres, as AC 50Hz, voltage 220/380V various types of electrical equipment power supply and current, voltage display.
1.2 Working conditions The altitude does not exceed 2000m;
The ambient air temperature is not higher than +40°C and not lower than -20°C;
Relative humidity of air does not exceed 90% (+20°C);
There are no significant shaking and violent impact vibrations.
2, structure and characteristics 2.1 model meaning
2 main technical parameters
2.3 Structure Overview The operation column is designed and manufactured in accordance with the requirements of GB3836.1~3-2000, and has passed the inspection and inspection by the state-specified inspection authority and issued the explosion-proof certificate. The outer shell of the operating column is cast aluminum alloy die-casting, with plastic sprayed on the surface, high strength, beautiful appearance and reliable performance.
Built-in transfer switches, ammeters, voltmeters, indicators, buttons, etc. are all Ex components. A universal switch can be used instead of a button, with one hole instead of a hole. A variety of features and specifications for user selection.
Operation column cable or steel pipe wiring can be, and can be tailor-made according to user requirements.
3, the outline diagram. example:
4. Installation and maintenance 4.1 Check whether the technical parameters listed on the nameplate are in accordance with the actual conditions before installation.
4.2 The pre-stage power supply must be cut off before maintenance;
4.3 Into and out of the cable through the rubber seal, and for the washer and compression nut compression, to ensure that the seal and the cable can not be loose;
4.4 During the maintenance and dismantling, please pay attention to the explosion-proof surface must not bump, scratch, and apply 204-1 anti-rust oil;
4.5 The operating column should be checked regularly during use to ensure its good operation;
4.6 Non-professionals must not open the lid;
4.7 The internal and external grounding must be good and reliable.
