Explosion proof operating column made of cast aluminum alloy material

Explosion proof operating column made of cast aluminum alloy materialA flexible control system that can provide customers with local control units or display units with standard or special requirements. We offer three types of standard enclosures to accommodate control and display in three different situations. At the same time, you can also combine three additional ComEx shells together according to your needs. The size of the wire entry head can be M20x1.5 or M25x1.5. The material can be plastic or metal. The plastic introduction head is directly threaded and does not require tightening nuts. The metal introduction head is fixed by a metal grounding plate inside the box. One operation column can have two M20 wire entry heads. For the convenience of on-site operation, each plastic shell is equipped with a license plate.

There are two types of explosion-proof products, dI and dIIBT4. ① dI is suitable for non mining working faces in coal mines; ② DIIBT4 is used in factories and is suitable for explosive gas mixtures in IIA and IIB level T1-T4 environments. The performance of this product meets the requirements of JB/T8528-1997<Technical Conditions for Ordinary Valve Electric Devices>. The performance of the explosion-proof type meets the requirements of GB3836.1-2000<General Requirements for Explosion proof Electrical Equipment for Explosive Environments>and JB/T8529-1997<Technical Conditions for Explosion proof Control Boxes>. And it has been verified by the National Explosion proof Electrical Product Testing Center and obtained the explosion-proof certificate and mining certificate The integral electrical installation is derived from the Z ordinary type, adding many electrical and electronic components. The integral ordinary electrical part mainly consists of multifunctional modules MK1, remote control modules MK2, button box indicator lights, opening meters, contactors, etc. The multifunctional module MK1 is composed of three parts: phase recognizer XS, contactor interlock protector HB, and DC power supply DC. The remote module MK2 consists of four solid-state relays and three dip switches. The overall regulating electrical part consists of regulating modules TMK, contactors, etc. The control line is 220V, 50Hz (special order 60Hz); Remote control includes DC24V, DC36V, DC127V, 220V, etc
