轮船装卸系统、堆取料输送机
智能跑偏开关是用于检测带式输送机运行过程中输送带跑偏程度并进行报警以及自动触发紧急停机的一种保护装置。使用跑偏开关可防止昂贵的输送带受损害以防止进一步的工矿事故和人生伤害。两级跑偏开关在安全运行输送系统里是不可缺少的保护装置,其广泛应用于钢铁厂、火力发电厂、水泥厂、化工厂、港口等。
Electrical parameters:
Voltage: 24V-48V-220V-380V-480V,
Current general: 1A, 2A, 3A, 4A, , 6A, 7A, 8A, 9A, 10a.15a.
The first level switch signal is used for alarm. If the signal is connected with the running adjustment device, it can realize the automatic adjustment of the running deviation in the no-stop condition.
The secondary switch signal is used for the shutdown, and the signal is connected to the control circuit, which can realize the automatic shutdown of the severe running deviation.
When the fault is removed, the roller can be reset automatically when the roller is running normally.
In order to adapt to the outdoor use for a long time, under the condition of this product adopts integral seal, galvanized purification processing internal metal parts, exterior parts except the hull for multilayer bright chrome plating, shell of aluminum/stainless steel, the surface adopts electrostatic spraying technology processing, suitable for use in harsh environments.
Working principle of deviation switch.
When running belt running deviation occur, edge tape drive extrusion rod rotation and tilt, if stick at the Angle of tilt Angle is greater than the level of action, switch signal a set of switches, such as the vertical rod continues to tilt Angle is greater than the secondary action is another set of switch output. The two sets of switch signals can be used for alarm or stop, and the belt machine can reset automatically after the machine is reset.
Adopt the import travel switch, the contact capacity is big, the action is sensitive, the service life is long.
Good sealing, dustproof, shock proof, anti-corrosion and other advantages.
Protection grade :IP67, can work in bad environment for a long time.
Technical indicators ambient temperature: - 30 ℃ - + 50 ℃; Relative humidity: no more than 85%.
Level 1 action point to 12 ° (15 °); Secondary action Angle of 30 °, 35 °); The limit Angle is 70 °
Number of contacts and capacity: 2 groups are normally open; 2 groups are normally closed; 5 a/AC 380 v
Protection grade: IP67.
Reset mode: automatic reset.
