Explosion proof bidirectional pull rope switch BSFLS Explosion proof bidirectional pull rope switch BSFLS Explosion proof bidirectional pull rope switch BSFLS Features: 1. The shell is made of high-strength aluminum alloy one-time die cast, and the surface is cleaned by high-speed shot blasting and high-pressure electrostatic spraying. The shell structure is compact and reasonable, with good strength, excellent explosion-proof performance, strong adhesion of surface plastic powder, good anti-corrosion performance, clean and beautiful appearance; 2. It is a sensing element for the automatic zone control of the conveyor; 3. It has the advantages of high strength, light weight, good sealing, and long service life; 4. Steel pipe or cable wiring. The shell of BXYLS and BSFLS explosion-proof bidirectional pull rope switches is made of high-strength aluminum alloy through one-time die casting, which has strong anti extrusion pressure and is not easy to deform. It can resist the impact of falling rocks, coal blocks and other objects during underground work without being damaged. The explosion-proof surface set on the switch shell can effectively isolate the impact of an explosion inside the shell on the underground working environment outside the shell. When an emergency occurs with the belt conveyor running underground in a coal mine, the explosion-proof pull rope switch can be activated to immediately stop and alarm, prevent the accident from expanding, and ensure personal safety at the work site. This switch is easy to install and use, and operates reliably. Working principle: When an emergency occurs on the belt conveyor site, the steel wire rope tied to the switch can be pulled, and the steel wire rope drives the swing arm to rotate, causing the travel switch inside the switch to act and generating a stop signal. Prevent the escalation of accidents. The BSFLS and BXYLS explosion-proof bidirectional rope switches are manually and automatically reset. After troubleshooting, the reset pin can be pulled to reset.
